TECHNICAL FIELD

This invention generally relates to centrifugal systems used to separate and/or isolate substances based on their density, size, viscosity, or shape for use in a variety of applications. More specifically, the invention relates to portable centrifugal systems used to separate blood into its blood components, including platelet poor plasma (PPP), platelet rich plasma (PRP) and red blood cells (RBC), as well as other different types of tissues, such as stem cells and its stem cell derivatives.

BACKGROUND INFORMATION

Currently systems used to separate blood to produce or separate into specific blood components, such as platelet poor plasma (PPP), platelet rich plasma (PRP) and red blood cells (RBC) commonly involve a centrifuge. Traditional blood separation centrifuges are based on three basic rotor designs: 1) the swinging bucket centrifuge; 2) the fixed angle centrifuge; and 3) the vertical tube centrifuge, where blood is injected into test tubes and spun within a chamber to induce a stacked or “cake-tier” separations.

Problems exist with current commercially available or traditional centrifuges. First, the conventional centrifuges are difficult to sterilize with the electrical components, in particular circuitry and power components and prevent them from being used in-situ in sterile environments requiring pre-processing or post-processing of a patient's blood. Secondly, cell damage may occur due to excessive steps with handling of the blood. Thirdly, extraction of blood components after centrifugation becomes exceedingly difficult and requires skilled personnel. The centrifugation process positions the blood components within the test tube in a stacked or layered configuration and requires specialized tools to properly extract the blood components without cross-contamination. Finally, the separation of the blood components usually results in at least 3 specific stacked layers of PPP, PRP, and RBCs, and if optimization of the concentrations of these blood components are desired, it requires multiple centrifugation cycles and excessive time to acquire the ideal concentration of each blood component.

SUMMARY OF THE INVENTION

Thus, a need exists for a blood separation system and process that (1) can be used in a sterile and/or non-sterile environment; (2) minimizes the number of handling and processing steps; (3) greatly simplifies the extraction of the blood components; and (4) allows automatic separation of different concentrations of PRP, tissue and/or stem cells with a single centrifugation cycle and/or reduced centrifuge cycles.

In some instances, the approximating language may correspond to the precision of an instrument for measuring the value.

Terminology used herein is for the purpose of describing particular examples only and is not intended to be limiting. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, references to “one embodiment” are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Moreover, unless explicitly stated to the contrary, the terms “comprising” (and any form of “comprise,” such as “comprises” and “comprising”), “have” (and any form of “have,” such as “has” and “having”), “include” (and any form of “include,” such as “includes” and “including”), and “contain” (and any form of “contain,” such as “contains” and “containing”) are used as open-ended linking verbs. As a result, any embodiments that “comprises,” “has,” “includes” or “contains” one or more step or element possesses such one or more step or element, but is not limited to possessing only such one or more step or element. As used herein, the terms “may” and “may be” indicate a possibility of an occurrence within a set of circumstances; a possession of a specified property, characteristic or function; and/or qualify another verb by expressing one or more of an ability, capability, or possibility associated with the qualified verb. Accordingly, usage of “may” and “may be” indicates that a modified term is apparently appropriate, capable, or suitable for an indicated capacity, function, or usage, while taking into account that in some circumstances the modified term may sometimes not be appropriate, capable, or suitable. For example, in some circumstances, an event or capacity can be expected, while in other circumstances the event or capacity cannot occur—this distinction is captured by the terms “may” and “may be.”

As used herein, the term “portion” is not limited to a single continuous body of material unless otherwise noted. A “portion” may include multiple sub-portions that may be the same or differing materials, and/or may include coatings, adhesives, and the like, and may be a separate and distinct component or may be an integral section, segment, or fragment of a larger component. As used herein, the term “coupled” is not limited to a direct coupling of two separate and distinct components. Two “coupled portions” may include indirectly coupled portions or directly coupled portions.

The systems, methods, and apparatus described are directed to a cordless and/or portable centrifugal device for use in a sterile and/or a non-sterile environment. The cordless and/or portable centrifugal device overcomes many of the disadvantages of the conventional centrifugal machines. The portable centrifuge (1) can be used in a sterile and/or non-sterile environment; (2) minimizes the number of handling and processing steps; (3) eliminates the need for test tubes and thus eliminates spills or breakage within the portable centrifuge; (4) greatly simplifies the extraction of the blood components; and (5) reduces or eliminates the need to balance the portable centrifuge with a “dummy” test tube(s); (6) allows automatic separation of different concentrations of PRP with a single centrifugation cycle; (7) fewer moving parts and fewer mechanical failures.

The portable centrifuge leverages the centrifugation principles to simplify extraction. The portable centrifuge is a device that is used to separate components of a mixture according to density, shape, viscosity, and/or particle size by depositing the separate components into their respective channels (see FIG. 104A-104B) rather than stacked-tiered layers or vertical layers via conventional rotor centrifuges. The portable centrifuge spins the mixture or whole blood in rotation using a fixed speed (RPM) around a fixed axis (spins it in a circle), which the whole blood or mixture is subjected to centrifugal forces. These centrifugal forces apply a force perpendicular to the axis of rotation (outward or horizontally) and/or parallel to the centrifugal force onto the mixture or whole blood causing the dense particles to migrate away from the axis of rotation (e.g. or move outward in the radial direction) and the lighter particles to move toward the axis of rotation. Once the components are deposited into each of the respective channels, each of the channels aligns with an extraction hole for easy visualization and extraction of the separated particles of a mixture or separated blood components of whole blood. Thus, eliminating the need for highly skilled personnel to extract the different components.

The portable centrifuge can exhibit a wide range of centrifugal forces or G-forces than compared to traditional rotor centrifuges. The portable centrifuge system exhibits a G-force or centrifugal force that comprises substantially zero and/or zero gravitational forces (or G forces) at the axis of rotation 698 and/or proximate to the axis of rotation 698. Accordingly, the G-forces progressively increases linearly in the radial direction from the smallest radius 695 (e.g. potentially smallest ring) towards the largest radius or largest ring on the sequester wheel, radius 1 690, radius 2 692, and/or radius 3 695 within the sequester wheel. The portable centrifuge may comprise G-forces from 0 to 10,000 Gs. This is highly contrasted by the traditional rotor centrifuges, which the traditional rotor centrifuges will never reach substantially zero or zero G-forces at and/or proximate to the axis of rotation 698. Each of the traditional centrifuges have substantially greater G-force due its minimum radius 687 and maximum radius 689 based on its design, which may be 2000 Gs and greater.

The portable centrifuge may desirably reduce or eliminate mechanical failures. The portable centrifuge does not include swinging parts (e.g., swinging bucket), nor does it require balancing prior to centrifugation. This is highly contrasted by conventional or traditional centrifuges. Conventional rotor centrifuges require the mixture or whole blood be placed into test tubes (see FIG. 103) and if there are an unequal amount of test tubes, the conventional centrifuge must be balanced to achieve uniformity of G-forces. G-forces may change dramatically by any slight differences in the uneven distribution of weight within the conventional rotor centrifuges. Furthermore, the conventional centrifuges, like the swinging bucket centrifuge, exhibit high metal stress due to the swinging of the bucket to a 90-degree angle when centripetal force is applied and can exhibit frequent mechanical failures. Accordingly, the length of time to stop the centrifugation process is delayed or slow to reduce the risk of contaminating or mixing the separated gradient layers.

In one exemplary embodiment, the portable centrifuge may minimize the number of handling and processing steps compared to conventional centrifugation techniques. The portable centrifuge provides for reduced handling and transferring of blood because the steps may be performed in a single location, thus reducing potential cross-contamination to extracted blood components and ensuring chain of title or chain of custody of the patient's blood. The portable centrifuge may comprise the steps of withdrawing the blood from a patient; injecting blood into portable centrifuge; activating centrifuge; and extracting blood components from the portable centrifuge; and injecting the extracted blood components into the patient. This contrasts with conventional techniques. Some conventional techniques involve a blood draw in a non-sterile separate location, which the blood is stored in a treated or non-treated test tube. The test tube is sent to a different lab for centrifugation cycle to separate the patient's blood into its separate components and then the specific components must be extracted and stored in second container for use or injection (e.g. syringe). The extracted components are then injected into the patient subcutaneously in a non-sterile environment potentially using visual guidance (e.g. ultrasound or fluoroscopy imaging). This conventional process is a time-consuming process.

In another embodiment, the portable centrifuge may comprise immediate separation of different concentrations of PRP's with a single centrifugation cycle. The PRP can be used “as-is” or it can be further separated into concentration 1 PRP and/or concentration 2 PRP. The PRP may be separated further into leukocyte-rich PRP (LR-PRP), defined as having a neutrophil concentration above baseline, and leukocyte-poor (LP-PRP) preparations, defined as having a leukocyte (neutrophil) concentration below baseline. In one embodiment, the PRP may comprise PRP concentration 1 and PRP concentration 2, the concentration 1 and/or 2 may comprise PRP, LP-PRP, LR-PRP, and/or any combination thereof. Such separation of the different concentrations of the PRP allows physicians to have specific recommendations for each separate concentration (PRP, LR-PRP and/or LP-PRP) for each musculoskeletal indication. Accordingly, the portable centrifuge may comprise a first blood component, a second blood component, and a third blood component. Alternatively, the portable centrifuge may comprise a first blood, component, a second blood component, a third blood component, and a fourth blood component, and/or any combination thereof. The portable centrifuge may comprise a first blood, component, a second blood component, a third blood component, a fourth blood component, a fifth blood component and/or any combination thereof. The blood components may include PPP, PRP, LR PRP, LP-PRP, RBC, and/or any combination thereof.

Applications

In another exemplary embodiment, the portable centrifuge may be used as an in-situ preparation for PPP and/or PRP therapies for musculoskeletal injuries and/or inflammation. Platelet-rich plasma (PRP) is a preparation of autologous human plasma with an increased platelet concentration produced by centrifuging a larger volume of a patient's own blood. Platelets contain a plethora of growth factors and mediators in their alpha granules (TGF-β1, PDGF, bFGF, VEGF, EGF, IGF-1), which are concentrated through the centrifugation process to release supraphysiologic amounts of these growth factors and cytokines to an injury site and augment the natural healing process. Platelet-rich plasma (PRP) therapy requires an injection of a concentration of a patient's own “active” platelets (e.g., the platelets may be activated with the addition of calcium chromide or thrombin) into injured or diseased body tissue to accelerate the healing of injured or inflamed tendons, ligaments, muscles, and joints. Then, the PRP releases the growth factors that stimulate and increase the number of reparative cells that a patient's body produces. PRP therapy can reduce the need for the administration of anti-inflammatories or stronger medications like opioids. In addition, the side effects of PRP injections are very limited because the injections are created from the patient's own blood, and the patient's body will not reject or react negatively to them.

In another embodiment, the portable centrifuge may be used as an in-situ preparation for convalescent plasma therapy that treats a disease condition where the pathogenesis is linked or associated to a specific toxic biologic substance and/or an infectious disease. Convalescent plasma therapy or plasmapheresis is the removal, and the return or exchange of blood components that contain antibodies into the patient for treatment of infectious diseases (e.g. COVID-19) and/or other toxic biologic substances. It can be used as a current or reactive treatment modality and/or used prophylactically to prevent infection. The portable centrifuge may allow for autologous plasma therapy, plasma exchange (PE, PLEX or PEX) or plasma exchange therapy (PET), and/or by donation. The portable centrifuge may further allow for single use, discontinuous flow centrifugation, continuous flow centrifugation, and plasma filtration. Discontinuous flow centrifugation requires a venous catheter line, and removal of 300 ml of blood at a time and centrifuged to separate plasma from blood cells. Continuous flow centrifugation may require two venous lines and requires slightly less blood volume out of the body at any one time, as it is able to continuously spin out plasma. Plasma filtration may require two venous lines and the plasma is filtered using standard hemodialysis equipment. This continuous process requires that less than 100 ml of blood be outside the body at one time. Single-use process comprises an injection of autologous or non-autologous (e.g. donation) blood to be centrifuged, which the centrifuged blood components, namely plasma, will be extracted and administered directly to the patient.

In another embodiment, the portable centrifuge may be used for treatment of various ocular or ophthalmological disorders, including, but not limited to dry eye syndrome, persistent epithelial defects (PEDs), neurotropic ulcerations, limbal deficiency and/or corneal dystrophies. The use of blood derivatives or blood components is highly desirable as a therapeutic approach to stimulate and accelerate tissue healing within the eye. The coagulated or anticoagulated blood may be centrifuged to separate into its constituent blood components, including plasma or serum (30% to 55%) and formed elements (70% to 45%) (e.g., formed elements includes RBCs, platelets and WBCs). Plasma and/or serum may be further filtered using a standard filtration media and administered using a variety of eye dispensing mechanisms. The eye dispensing mechanisms may comprise a pipette, a syringe, an eye dropper, and eye dropper with integral filter, a mechanical dispenser, and/or any dispensing mechanisms known in the art. The serum or plasma eye drops may be used as a reactive treatment modality and/or be used prophylactically. The serum or plasma eye drops may comprise autologous or non-autologous blood components.

In another embodiment, the portable centrifuge may be used for rapid and accurate assessment of blood hemostasis via microfluidic technology in conjunction with centrifugation (e.g., separation of blood into its blood constituent components). Rapid, quantitative and accurate hemostasis monitoring is critical in many clinical settings (for example, surgery, trauma, sepsis, anticoagulation and anti-platelet therapies) to anticipate, avoid and direct the management of serious disorders due to bleeding or thrombosis. An increasing number of patients are diagnosed with COVID-19 require precise and personalized anticoagulation dose monitoring on as close to real-time basis as possible to maintain homeostasis in-vivo to prevent any serious health effects from COVID-19 coagulopathies. Therefore, the lack of managing anticoagulation dosage precisely and continuously is a common cause of catastrophic hemorrhage and mortality in patients. Moreover, the requirement for monitoring homeostasis reliably at the bedside using low blood volumes is even more critical in pediatric patients with acute coagulopathy (acquired or congenital), as they are more vulnerable than adults. As a result, the portable centrifuge may comprise a simple microfluidic device for real-time monitoring of hemostasis and platelet function that permits rapid determination of a clotting time for native whole blood as it is perfused through a network of channels. The network of channels may be configured in such a way to potentially mimic local physiologically relevant changes in hemodynamics flow conditions experienced in living stenosed arterioles.

In another embodiment, the portable centrifuge may be used for isolation of different types of stem cells from embryonic and/or adult tissues for use in stem cell therapies (e.g., regenerative medicine) and research. Stem cells are characterized as cells endowed with continuous self-renewal ability and pluri- or multipotentiality and could consequently give rise to a large panel of cell types. Isolation of a large volume of stem cells with purity and viability must be completed to be useful for treatment purposes, thus leading to the development of stem cell separation technologies. The portable centrifuge may offer isolation of embryonic or adult stem cells via density gradient and/or differential centrifugation techniques without the complexity of steps of standard techniques, thereby minimizing sample variability, meeting the purity and viability standards and delivering more efficient on-site isolation.

More specifically, the height of the rings (e.g. the first ring 114, the second ring 115, and the third ring 116) may be, approximately 8 mm. Each of the heights may be the same or they may be different.

With continued reference to FIGS. 29-35, the first channel 141 and the second channel 142 may each have as an example, an approximate volume of 2.5 ml.

The spokes 117 are engaged with the sequester wheel tabs 112 holding the sequester wheel 105 in position against the spring 109 and maintaining compression. The centrifuge cover 104 may be, for example, placed onto the baseplate 106 and sealed to create a liquid impermeable connection. Polymer barriers may be used to, for example, seal openings in the baseplate 106 (e.g. the plurality of tabs 112 and the toggle hole 127) and openings in the centrifuge cover (e.g. the plurality of extraction holes 121 and the at least one insertion hole 122) to create a sealed, liquid impermeable container.

With reference to FIGS. 18-23, the internal chamber of the centrifuge container 130 may have, for example, a height of approximately 10.5 mm to 13.5 mm and an internal diameter, for example, of approximately 60 mm to 70 mm. More specifically, the dimensions may, for example, be sized to accommodate 30 ml of fluid in addition to the internal components (e.g. the spring 109, the toggle 111, the plurality of tabs 112, and the sequester wheel 105) resulting in an internal chamber of approximately, 12.5 mm between the baseplate topside 132 and the centrifuge cover bottom side 135 and having a diameter of approximately 68 mm (e.g. total volume of approximately 45 ml). For the centrifuge container 104, separation may be, for example, performed on approximately 27 ml to 30 ml of blood, and more specifically, 30 ml. The clearance between the top of the rings (e.g. the first ring 114, the second ring 115, and the third ring 116) and the bottom surface 135 of the centrifuge cover 104 may be, for example, approximately 1 mm to 3 mm, and more specifically, approximately 1 mm. The sequester wheel 105 may be, for example, positioned within the centrifuge container 130 resulting in a third channel 143 between the third ring 116 and the sidewall 137. The spacing of the plurality of extraction holes 121 align with a hole above each of the third channel 143, the second channel 142, the first channel 141, and the inner section 144.

With reference to FIGS. 1, 2, 7, 8, 14-17, and 28-31, the centrifuge motor base connector 120 of the centrifuge container 130 is connected to the motor armature 161, with a clearance between centrifuge baseplate 106 and the base cover, ranging from 1 mm to 5 mm, and more specifically, approximately 2 mm. The protective cover 103 is placed over the centrifuge container 130 and onto the base cover 102, such that the activation tab 108 is inserted through activation slot 107 and an activation slider slot 156 of the activation switch 160. The protective cover 103 may be sized to, for example, cover the centrifuge container and allowing the centrifuge container 130 to rotate without making contact with the inner surface of sidewall 140 or the bottom side 139. There may be, for example, a clearance of approximately 1 mm to 5 mm, and more specifically, approximately 3 mm between the bottom side 139 of the cover 103 and the top side 136 of the centrifuge container 130. There is a clearance of approximately 1 mm to 5 mm, and more specifically, approximately 3 mm between the sidewall 137 and the sidewall 140. The activation switch 160 has the activation slider slot 156 within the activation slider or sliding switch 157, a conductive member or magnetic member 158 connected to the activation slider 157, and a plurality of circuit members 159.

Referring to FIGS. 1-43 and 87, the centrifuge may be sealed and sterilized prior to use and introduction to a sterilized environment, such as, for example, a surgical operating room. A method of using centrifuge 100 may include, removing the protective cover 170 and introducing blood into the centrifuge container 171 through the insertion hole 122 using a sharp object, such as, for example, a syringe (not shown). The introduced blood may, for example, flow from the inner section 144 and through the spokes 117 and the channels 124 to accommodate the full volume of blood.

Still referring to FIGS. 1, 2, 7, 8, 14-17, 28-31, and 87, the method may also include replacing the protective cover 172, and turning or twisting the protective cover to activate the centrifuge 173. Turning the protective cover may, for example, cause the activation tab 108 to move the activation slider 157, connecting the conductive member 158 with the plurality of circuit members 159 and completing a circuit to activate the rotational mechanism 110. The centrifuge container 130 may be, for example, rotated under the protective cover 103 by the motor 154 at, for example, approximately 10,000 rpm to 25,000 rpm, and more specifically at 20,000 rpm. The blood may separate into constituent components 174. The blood may, for example, separate into constituent columns and/or channels, with the RBC in a column approximately towards the sidewall 137 and above the third channel 143, the PRP in a column approximately above the first channel 141 and the second channel 142, and PPP remaining approximately within the inner section 144. There PRP column may be, for example, in a gradient of concentration between the PPP and RBC columns. The plurality of spokes 117 and the plurality sequester wheel channels 124 may also, for example, allow for blood to flow through and around during centrifugation, aiding to lessen a fluid path and shear on the cells. By constraining the volume of blood (e.g. 30 ml) introduced into a centrifuge container having a slightly greater volume (e.g. approximately 45 ml), thick columns of PPP, PRP, and RBC may be created and visible during centrifugation. A timer within the circuit board 151 may send a signal to activate the toggle switch 175. The timer within the circuit board 151 may be, for example, triggered upon rotational mechanism 110 activation. Upon reaching a threshold time, the circuit board 151 may, for example, trigger the solenoid 153, extending the solenoid armature 163 to make contact with the toggle switch 111. The toggle switch may activate the sequester wheel 176. The toggle switch 111 may, for example, pivot within the toggle supports 119, pushing or rotating against the canted member 148, pushing or rotating the sequester wheel 130, and freeing the sequester wheel 105 from the plurality of tabs 112. The sequester wheel may then capture the PRP 177. The compressed spring 109 may, for example, project the freed sequester wheel 105 in an approximately perpendicular direction to the baseplate 106. The projection may be, for example, with sufficient force for the top of the sequester wheel 105 to strike the centrifuge cover bottom side 135. However, the toggle switch 111 may, for example, be positioned through the baseplate 106 and the sequester wheel 105 to inhibit the sequester wheel 105 from rotating independently from the baseplate 106 after release from the plurality of tabs 112. The projected sequester wheel 105 may, for example, capture the PRP within the channels (e.g. the first channel 141 and the second channel 142). The timer on the circuit board 151 may send a stop signal to the electrical motor 178 and the centrifuge container may stop rotating 179. At a second threshold time, the circuit board 151 may, for example, open the circuit, and the centrifuge container 130 rotation slows until stopping. The RBC column may, for example, approximately fall into or remains within the third channel 143, with the PRP column falling within the second and first channels 142, 141, and the PPP column falling into within the inner section 144. The PRP may, for example, have a gradient of PRP concentrations between the first and second channels 141, 142. Within the first channel 141 and the second channel 142, the volume of PRP accumulation may be, for example, from approximately 3 ml to 5 ml, based on 30 ml of blood. The protective cover may be removed 180 and the blood constituent components may be removed 181. After the protective cover 103 is removed, the separated blood elements may, for example, be withdrawn from the plurality of extractions holes 121. The blood constituent components may be, for example, withdrawn by inserting a syringe needle (not shown) through one of the pluralities of extraction holes 121 aligned with the desired blood component. Removing PRP may include, inserting a syringe needle through one of the plurality of extraction holes 121 that are aligned with the first channel 141 or second channel 142, and then pulling the plunger to withdraw the constituent component into the syringe (not shown). Removing PPP may include, for example, inserting a syringe into insertion hole 122. While a syringe has been described for use in extracting blood from centrifuge 100, one having ordinary skill in the art would understand that other tools that may be used.

In other aspects of the centrifuge 100, the number of channels in a sequester wheel 105 may range from a single channel to five channels, with an inner ring and an outer ring having approximately the same dimensions to the first ring 114 and the third ring 116. In other aspects of the centrifuge 100, the centrifuge container 130 may be sized to, for example, hold ml of fluid and internal components (e.g. the spring 109 and the sequester wheel 105), with the internal diameter of the centrifuge container 130 remaining approximately 60 mm to 70 mm, but having a height to accommodate the greater volume. In still other aspects of the centrifuge 100 for holding 60 ml of fluid, the height of the sequester wheel 105 may range from, approximately 21 mm to 25 mm. In other aspects of the centrifuge 100, rotation of the centrifuge container 130 may be slowed by the presence of a brake button on the protective container 103 to frictionally slow the centrifuge container 130. In still other aspects, the solenoid armature 163 may remain extended and contacting the toggle switch 111, aiding with braking the centrifuge container 130.

Referring now to FIGS. 45-73, an alternate embodiment for centrifuge 300 is shown. The centrifuge 300 has a protective cover or third member 302, a base frame, first member, or base ring 303, a base frame cover 304, and a cap assembly 310. The centrifuge 300 has a conical frustrum shape, with the base ring 303, the base frame cover 304, and the protective cover 302 having a large diameter at the bottom of the centrifuge 300, and the protective cover 302 narrowing towards the region at the top of the centrifuge 300 where a cap 301 of the cap assembly 310 is engaged as shown in FIGS. 45-51. The base frame cover 304 is connected to and above the base ring 303. The protective cover 302, is engaged with and above the base frame cover 304. The cap 301 is engaged at the top of the protective cover 302 and at the top of centrifuge 300.

With continuing reference to FIGS. 45-51 and 65-68, the cap assembly 310 is shown with the cap 301, a cap arm 305, an activation handle 306, an activation tab 307, and a cap connector 324. The cap assembly 310 may be, for example, constructed from a rigid plastic polymer material. The protective cover 302 has a protective cover opening or first opening 309, that is approximately circular, at a top end and extending at an approximately 45° to 50° angle to a protective cover base opening or second opening 327. The angle of the protective cover 302 may be, for example, more specifically be approximately 45°. The second opening may be, for example, approximately circular. The circumference of the first opening 309 may be, for example, smaller than the circumference of the second opening 327, with the openings being sufficiently large to cover the inner components of the centrifuge 300. The protective cover 302 has a first connector 326 along the circumference of the first opening 309 and a second connector 328 along the circumference of the second opening 327. The cap 301 may be, for example, circular with a diameter of approximately 75 mm. The cap 301 may, for example, engage with the protective cover 302, such that the cap connector 324 engages with the first connector 326 within the first opening 309. The cap arm 305 extends away from cap 301 at, for example, approximately 45° to 50° and more specifically at approximately 45°, extending towards the first connector 326. The cap arm 305 may, for example, have a length of approximately 70 mm to 80 mm, or more specifically, approximately 75 mm. The cap arm 305 may, for example, extend away from cap 301 and have an articulated section 325 distal to cap 301. The articulated section 325 may, for example, be at an angle to the rest of cap arm 305. The activation tab 307, extends from the second end of the articulated section 325 at an angle, and may be, for example, approximately perpendicular to the articulated section 325. The activation tab 307, may for example, have an approximately triangular shape.

Referring to FIGS. 52-56 and 69-71, the protective cover 302 may be, for example, removable from the centrifuge 300. The first connector 326 is configured (e.g. shaped and dimensioned) to engage with the base frame cover 304 when placed onto the centrifuge 300. Below the protective cover 302, centrifuge 300 has a rotating test-tube holder, test-tube armature, second member, or rotor 312, engaged with the motor 154. The rotor 312 may be, for example, conical frustrum shaped, having a circular top surface 319 with, for example, a diameter of approximately 113 mm. A circumferential sidewall 335 extends away from the top surface 319 at, for example, an approximate angle of 45° to 50° to a circular rotor bottom or ring 336, and more specifically, at approximately 45°. The rotor bottom 336 has an opening that extends to the top surface 319, with the rotor bottom 336 having a diameter of, for example, approximately 212 mm. The height of the rotor 312 may be, for example, approximately 65 mm.

Still referring to FIGS. 52-56 and 69-71, the rotor 312 holds a plurality of test-tubes 350, with each test-tube sized to, for example, 10 ml to 30 ml of fluid, and more specifically hold ml of fluid. The test-tube may have, for example, a stoppered or a sealed opening. The top surface 319 has a plurality of test-tube slots 320, having openings at the top surface 319 and extending along an inner wall 316 of the rotor 312. The test-tube slots 320 have side walls extending from the inner wall 316, forming a channel with a curved bottom support 313, for engagement with a test-tube of the plurality of test-tubes 350, and providing approximately 0.5 mm of clearance between test-tube slot side walls and the test-tubes 350. Two test-tubes 350 are shown, however aspects of centrifuge 300 may, for example, hold up to and including eight test-tubes 350.

Continuing to refer to FIGS. 52-56 and 69-71, the underside of the rotor 312, may have, for example a plurality of buttresses or member 318 positioned as diametrically opposed pairs extending from the inner wall 316 toward a motor engagement support 317, axially aligned with the approximate center of top surface 319 and the approximate center of the bottom opening 327.

With reference to FIGS. 56-58 and 72-73, the base frame cover 304 has a top side 332, a bottom ring 329, an outer rim 331, and a plurality of protrusions 321. The base frame cover 304 may be, for example, also conical frustrum shaped, having a hole 323 extending from the top side 332 to an inner circumference of the bottom ring 329. The plurality of protrusions 321 extend from a bottom side of the bottom ring 329 for engagement with a plurality of connection holes 322, extending from an upper surface to a bottom surface of the base ring 303.

With reference to FIGS. 58-62, the base ring 303 is shown with a rotational mechanism or a centrifuge motor or centrifuge drive 330 and an activation armature 308 extending from the base ring 303 to the base plate 101 of the centrifuge motor 330. An activation armature slot 314 may be a channel following, for example, an arc of the base ring 303. A first end 333 of the activation armature 308 slot is movable within the armature slot 314, for example, along the arc of the base ring 303. A second end 334 of the activation armature 308 passes through an activation slot 315 through the baseplate 101 and connecting to the rotational mechanism 330.

Referring to FIGS. 1, 2, 64A, 59, and 64B, the rotational mechanism 330 is shown with the electric motor 154, the circuit board 151, the control relay 152, the at least one battery 155, and the activation switch 160 connected to form an open circuit. The rotational mechanism 330 is connected to the baseplate 101 and is covered by the base cover 102 such that the armature 161 of the electric motor 154 extends through the housing opening 118. The rotational mechanism 110 has been explained above in detail and the rotational mechanism 330 will not be described further for brevity sake, except to note that the rotational mechanism 110 has the solenoid 153 whereas rotational mechanism 330 does not. All other internal components are the same.

As shown in FIGS. 57-58, the base frame cover 304 may be, for example, connected to the base ring 303 with the plurality of protrusions 321 engaged with the connection holes 322. The base frame cover 304 may be, for example, further engaged with the rotational mechanism housing or base cover 102 with the housing opening 118 aligned with the hole 323. The activation armature slot 314 may be, for example, covered by the base frame cover 304, forming, for example, a transverse slot covered with a top and a bottom and with the activation armature 308 remaining laterally movable within the slot 314 along the arc of the base ring 303.

With reference FIGS. 60, 63-64B, the second end 334 of the activation armature 308 may be, for example, connected to the activation switch 160 through the activation slot 315. The activation armature 308 further has a cap-arm engagement slot 311 on the first end 333, with the cap-arm engagement slot 311 shown as a triangular slot, extending from the first end 333 towards the second end 334. Moving the first end 333 of the activation armature 308 along the activation armature slot 314, moves the armature second end 334 along the activation slot 316, thus moving the sliding switch 157 along the activation slider slot, to activate the rotational mechanism 330.

With reference to FIGS. 56, 58, 70, and 71, the base frame cover 304 may be, for example, engaged with the base ring 303 and with the centrifuge cover 104, with the housing opening 118 aligned with the hole 323. The motor engagement support 317 of the rotor 312 may be, for example, connected to the armature 161 of the motor 154, such that the armature 161 is axially aligned with the motor engagement support 317. The rotor 312 connected to the armature 161 is configured (e.g. sized and dimensioned) and positioned above the base frame cover 304 with a clearance of approximately 1 mm to 3 mm. More specifically, there may be, for example, a clearance of approximately 3 mm. The motor armature 161, the base motor connector 120, the baseplate 106, the axle 126, and the sequester wheel hub 147 are all connected for coaxial alignment and rotation about the common axis 365. The common axis 165 may be, for example, the rotational axis of the armature 161.

Referring to FIGS. 52-54, the protective cover 302 may be, for example, positioned onto the base frame cover 304 such that the outer rim 331 and the second connector 328 are engaged. The protective cover 302, covers the rotor 312 however, the test-tubes 350 may extend out through the cover opening. The protective cover 302 is configured (e.g. sized and dimensioned) such that rotor 312 may be, for example, rotatable under the protective cover 302, there being a clearance of, for example, approximately 1 mm to 3 mm, and more specifically, a clearance of approximately 3 mm. Thus, rotor 312 may be, for example, rotatable by the electric motor 154, having clearance from both the base frame cover 304 and the protective cover 302.

With reference to FIGS. 45, 46, and 49, the cap assembly 310, may be, placed onto the protective cover 302 with the cap connector 324 engaged with the protective cover top rim 326. The cap 301 covers the cover opening 309 with a clearance provided between the test-tubes and the cap, ranging from 1 mm to 3 mm. The cap arm 305 extends along the cap 301 from approximately the cover opening 309 towards the protective cover bottom rim 328. The articulated section 325 is shown extending past the protective cover bottom rim 328 and towards the base ring 303, such that activation tab 307 is engaged with the cap-arm engagement slot 311. The cap arm slot 311 and the activation tab 307 are shown having a triangular shape, however other shapes and configurations may be used. The activation handle 306 extends from the cap arm 305 such that it may be, for example, grasped, pressed, pulled, or pushed to activate the centrifuge 300.

With reference to FIGS. 45-79 and 90, the centrifuge 300 may be sealed and sterilized, with the test-tubes 350 also being sterilized and included with the centrifuge 300. The test-tubes 350 may further have, for example, a thixotropic separation gel and an anti-coagulant included within, to aid in blood separation during and after centrifugation. The method for centrifugation includes removing the cap assembly 370. Blood may be introduced into the test-tubes 371. With test-tubes 350 already inserted into the test-tube slots 320 of rotor 312, blood may be, for example, introduced into the test-tubes 350 using a syringe (not shown). The cap assembly 310 may then be replaced 372. The cap 301 may, for example, cover the cover opening 308, with the cap connector 324 being engaged with the protective cover top rim 326, and the activation tab 307 inserted into the cap-arm engagement slot 311. The activation handle 306 may be pressed 373. For example, pressing or grasping and moving the activation handle rotate the cap assembly 310, with the cap 301 rotating within and along the circumference of protective cover top rim 326, the cap arm 305 rotating along the outer surface of the protective cover 302, and the activation tab 307, engaged with cap-arm engagement slot 311, rotating along the arc of the activation arm slot 314. As the activation tab 307 and the cap-arm engagement slot 311 are engaged, the activation armature first end 333 may be, for example, slid along the activation arm slot 314 and the activation armature second end 334, through the activation slot 315, moves the sliding switch 157 along the activation slider slot 156. When the conductive member 158 on the sliding switch 157 makes contact with the circuit members 159, the circuit may be, for example, closed and the motor 154 is activated. The blood may interact with the thixotropic separation gel and the anti-coagulant 374 and the blood may separate into constituent components 375. The separation gel may create a barrier for the RBCs, while the anti-coagulant may inhibit PRP and PPP from coagulating. The timer sends a signal to the motor 376. The motor 154 may, for example, continue rotating the rotor 312 until a timer on circuit board 151 opens the circuit, suspending power to the motor 154. The rotor 312 may continue to rotate until stopped 377. The cap assembly 310 may be removed 378. Removing the cap assembly 310 provides access to the test-tubes 350 and the blood, separated into RBC, PRP, and PPP. The blood constituent components may be removed from the test-tubes 379. Blood may be removing using a sharp object like, for example, a syringe.

With reference to FIGS. 74-86, yet another alternate embodiment of centrifuge 400 is shown. The centrifuge 400 has the rotational mechanism 330 on the baseplate 101 which is enclosed within base cover 102.

The protective cover has, for example, an approximately circular top side 409 that extends to the bottom side 410 and with a circumferential sidewall 411 extending away from the top side 409 and/or bottom side 410 to a cover rim 449. The cover rim 449 has an opening extending to the bottom side 410. The activation tab 408 extends from the cover rim 449 of the sidewall as a freestanding member. The protective cover 403 is configured (e.g. shaped and dimensioned) to cover the centrifuge container 430, while providing clearance between an interior surface of the protective cover 403 and the centrifuge container 430, and with the activation tab 408 inserted into the activation slot 107. The brake 401 may, for example, be a button of a flexible plastic material or from a plastic living hinge, and having a first and second position. The brake 401, when pressed, extends from the first position to the second position to make contact with the centrifuge container 430. The brake 401, may, for example, return to the first position when no longer depressed. In another aspect, the brake 401 may remain extended in the second position even after no longer being depressed.

With reference to FIGS. 76-86, the centrifuge container 430 has a centrifuge cover 404 and tiered separation wheel or sequester device 405. The centrifuge cover 404 may be, for example, a disc with a top side 436 and a bottom side 435, with a centrifuge cover sidewall 437 extending away from the disc to a first end or centrifuge cover connector 423 forming a ring or tube that is open at the first end 423. The centrifuge container 430 may have, for example, a height of approximately 29 mm to 35 mm, and more specifically 32 mm, from the first end 423 to the bottom side 435. Several holes exist, extending from the top surface 436 to the bottom surface 435, including a plurality of extraction holes 407 and at least one insertion hole 402. The plurality of extraction holes 407 may have an extraction barrier 443 occluding the plurality of extraction holes 407. Two of extraction barrier 443 are used to cover the two sets of the plurality of extraction holes 407, as shown in FIG. 86. Another barrier (not shown) may also be placed to occlude insertion hole 402. The extraction barrier 443 may be, for example, circular or ovular, fabricated from a plastic polymer material, and penetrable using a sharp object like, for example, a syringe.

The first end comprising a tapered end or a drafted end, the tapered end or drafted end being a 0.5% to 3% tapering, and/or a 0.5% to 1.5% tapering. Desirably, the tapering produces a draft angle between 0.5 degrees to 5 degrees to facilitate easy release of molds during manufacturing, and also helps facilitation of the blood product during centrifugation to climb or scale the walls easily and deposit in the plurality of channels and/or cavity.

With continued reference to FIGS. 77-86, on a second side 445, the sequester device 405 has a base ring 414 and a motor connector or armature hub 422, extending from the underside of the inner container 420. The armature hub 422 may, for example, form an axis passing through the concentric center of the base ring 414, the first ring 416, the second ring 417, the third ring 418, and the fourth ring 419. There may be, for example, a channel between the base ring 414 and the underside of the inner container 420. The first ring 416, may be, for example, 24 mm to 28 mm, extending from the base ring to the top of the first ring 416, and more specifically 25 mm. The first ring 416 may have, for example, a diameter of 58 mm to 61 mm, and more specifically 61 mm. The second ring 417 may, for example, have a diameter of approximately 50 mm to 53 mm, and more specifically a diameter of 53 mm. The third ring 418 may, for example, have a diameter of approximately 43 mm to 46 mm, and more specifically a diameter of 46 mm.

With continued reference to FIGS. 77-86, the sequester device 405 has a slope, for example, of approximately between 5° and 45°, and more specifically a slope of approximately 20°. The height difference between each tier of the first ring 416, the second ring 417, the third ring 418, and the fourth ring 419, may be, for example, from 1.5 mm to 2 mm. The inner container 420 may have a height of, for example, approximately 20 mm from the bottom to the top of the fourth ring 419. The third ring 418 may be, for example, 2 mm above the fourth ring 419, and may have, for example, an approximate depth of 6 mm to the first channel 440 bottom. The second ring 417 may be, for example 2 mm above the third ring 418 and may have, for example, an approximate depth of 6 mm to the second channel 441 bottom. The first ring 416 may be, for example 2 mm above the second ring 418 and may have, for example, an approximate channel depth of 6 mm to the third channel 442 bottom.

The plurality of rings 416, 417, 418, 419 and/or the at least one concentric ring 419 comprises a shape. The shape includes a circle. The shape can further include regular polygons, such as a triangle, a square, a pentagon, a hexagon, a septagon, an octagon and/or any other combination thereof. Alternatively, other shapes may include symmetrical polygons. The shape of the plurality of rings 416, 417, 418, 419 may be the same or it may be different. The shape of each of the plurality of rings 416, 417, 418, 419 may be the same or it may be different.

With reference to FIGS. 74-78, the centrifuge cover 404 is connected with the sequester device 405 with outer rim 415 and the cover connector 423 engaged and/or sealed, creating a liquid impermeable connection, and forming the centrifuge container 430. The centrifuge cover may be, for example, cylindrical and have an axis between the center of sequester device 405 and a center of the centrifuge cover 404. A fourth channel 412 is created between the inner side of the sidewall 437 and the outer wall of the first ring 416, with the base ring 414 providing a channel bottom. The fourth channel 412 may have, for example, a volume of 10 ml to 11 ml and more specifically, a volume of 11 ml. Each of the first channel 440, the second channel 441, the third channel 442, and the fourth channel 412 may be aligned with one of the pluralities of extraction holes 407. The centrifuge container 430 may be, for example, connected to the rotational mechanism 330, with the motor armature 161 and the armature hub 422, connected having coaxial alignment and rotatable about the common axis 465. The common axis 165 may be, for example, the rotational axis of the armature 161. Clearance between the bottom of the base ring 414 and the base cover 102 may range from, 1 mm to 3 mm, and more specifically, approximately 2 mm. The protective cover 403 may be placed over centrifuge container 430, with activation tab 408 placed into activation slot 407 and into activation slider slot 156. There may be, for example, clearance between centrifuge container 430 and protective cover 403, with the clearance ranging from 1 mm to 3 mm, and more specifically, approximately 3 mm.

With reference to FIGS. 74-86 and 89, the method of use for the centrifuge 400 includes, removing the protective cover 470. Blood may then be introduced into the centrifuge container 471. Approximately, 30 ml of blood may be, for example, introduced into the centrifuge container 404 by a syringe, inserted through the insertion hole 402. The protective cover may then be replaced 472. Replacing protective cover 403 may include, inserting the activation tab 408 through activation slot 107 and into the activation slider slot 156. The protective cover may then be turned to activate the centrifuge 473. For example, as the protective cover 408 is turned, the conductive member 158 contacts the circuit members 159 and completed a circuit. A timer is triggered and the centrifuge container 430 may be, for example, rotated under the protective cover 403 by the motor 154 at, for example, approximately 10,000 rpm to 25,000 rpm, and more specifically at 20,000 rpm. The blood may separate into constituent components 475, with RBC flowing into the outer channel 476, PRP flowing into the tiered ring channels 477, and PPP may remain in the inner container 478. The blood may, for example, separates into constituent columns, with the RBC approximately in a column towards the sidewall 437 and above the fourth channel 412, the PRP approximately in a column above the first through third channels (e.g. the first channel 440, the second channel 441, and the third channel 442), and a PPP column approximately remaining within the inner container 420. A timer may send a stop signal to the motor 479 and the centrifuge container may stop rotation 480. As the timer opens the circuit and the centrifuge container 430 slows to a stop, the separated columns may, for example, fall or flow into their respective close-proximity channels, with the RBC column falling or flowing into the fourth channel 412, the PRP column falling or flowing into the first through third channels (e.g. the first channel 440, the second channel 441, and the third channel 442), and the PPP remaining in the inner container 420. The PRP may have, for example, a gradient of concentrations between the first channel 440 and the third channel 442.

With continued reference to FIGS. 74-86 and 89, the centrifuge container may stop rotation 480. The brake 401, may be, for example pressed, to make contact with the centrifuge container top side 436, using frictional contact to slow or stop the centrifuge container 430 from spinning. When the centrifuge container 430 stops, the protective cover 403 may be removed 481. The constituent components of blood may then be removed 482. The desired blood component (e.g. RBC, PRP, and PPP) may then be, for example, removed using a syringe (not shown) through one of the plurality of extraction holes 407, by piercing the extraction barrier 443, with a sharp object, such as, for example a syringe.

It is contemplated that the sequester wheel 405 of the centrifuge 400 may have, for example, one channel to five channels.

However, the raised region 611 may be any shape around the center of the top surface. Extending out from the raised region 611 is an insertion tube or port 613, having an opening or a hole 609 disposed on a top surface of the insertion tube or port 613. The insertion tube or port 613 and the raised region 611 may be, for example, approximately concentric with the top surface 615. The tube or port 613 extending from the raised region is shown as cylindrical, but may also be any shape. The hole 609 in the tube 613 may be, for example, sufficiently large and shaped to accommodate a syringe needle or cannula inserted into the hole 609, as shown in FIG. 91. A syringe 699 is shown with a cannula inserted into hole 609.

Referring to FIGS. 93-94 and 106, the external sidewall 617 extends from the top surface 615 to a bottom rim 623. The bottom rim 623 forms an opening 622 extending to a bottom side 626 of the top surface 615. The circumference of the opening 622 defines the internal sidewall 618. The bottom side 626 is opposite the top surface 615. A cavity 620 may be, for example, recessed into the bottom side 626 towards the top side 615, forming the raised region 611 extending from the top surface 615. The opening 609 extends through the bottom side 626. A seal or insertion barrier 619 may be, for example, positioned within the perimeter of the cavity 620 and separating the opening 609 from the interior of the protective cover 601. The insertion barrier 619 may be, for example, a circular or ovular membrane, fabricated from a plastic polymer material, and penetrable using a sharp object like, for example, the cannula of the syringe 699.

The protective cover 601,702 has an activation tab 608 extending from the bottom rim 623 as a freestanding member, configured (e.g. shaped and dimensioned) for insertion into the activation slot 107. The protective cover 601,702 is configured (e.g. shaped and dimensioned) to cover the centrifuge container 610 and/or the sequester wheel 405,706, while providing clearance between an interior surface of the protective cover 626 and the centrifuge container 610 and/or the sequester wheel 405,706, and with the activation tab 608 inserted into the activation slot 107. The protective cover 601,702 further has a brake 607, which is similar to brake 401 and having already been described above, for the sake of brevity, will be described to note additional embodiment elements. The brake 607 may have, for example, a brake pad 612 extending from the bottom surface 626. The brake pad may be, for example, wedge shaped and positioned between the center of the bottom surface 626 and the sidewall 617, thickening in the direction of the sidewall 617. The protective cover 601,702 may, for example, be fabricated from a clear plastic polymer material or a material through which blood separation columns and/or plurality of rings may be visible.

In another embodiment, the protective cover 601,702 may comprise at least one light or a plurality of lights (not shown). The at least one light or the plurality of lights comprises a fluorescent lamp (CFL), an incandescent bulb, a halogen bulb, a light emitting diode (LED) bulb, an ultra-violet (UV) light, and/or any combination thereof.

With a Luer Lock connector, a seal 619 may, for example, not be required. Also, during centrifugation, the syringe with the male Luer Lock connector may, for example, remain connected to the female Luer Lock connector.

The protective cover 601,702 may further comprise an insertion barrier 619. The insertion barrier is positioned between the opening 609 and the insertion opening 630. In embodiments where the insertion barrier 619 covers the cavity 620, a sealed space may, for example, exist between the protective cover 601,702 and the container cover 625,704 when the protective cover 601,702 is engaged, with the activation tab 608 inserted into the activation slot 107. The insertion tube or port 613 of protective cover 601,702 may be, for example, aligned with the insertion tube or port 629 of the container cover 625,702.

Referring to FIGS. 92, 95, 106, 110A-110B, 112A-112C and 113A-113B, the portable centrifuge 600,700,738,744 may further comprise a container cover 625,704,740,746.

The top surface 631,724 comprise a circular shape with the insertion tube or port 629 approximately concentric or centered with the top surface 631,724. The top surface 631,724 and the insertion tube or port 629 are configured (e.g. shaped and dimensioned) for the protective cover 601,702 placement over the centrifugal container 610 and/or the sequester wheel 405,706 without inhibiting rotation of the centrifuge container 610 and/or the sequester wheel 405,706. The top surface 631,724 may further comprise one or more extraction regions 606, the one or more extraction regions 606 are spaced apart. The one or more extraction regions 606 may be spaced apart symmetrically or non-symmetrically around the circumference of the top surface 631,724. For example, the top surface 631,724 has a first extraction region and a second extraction region, the first extraction region and the second extraction region are spaced apart and/or diametrically opposed. The top surface 631,724 may, for example, have an external circumferential sidewall 627,734, with the sidewall 627,734 extending away from the top surface 631,724 and connected to an outer rim 415 of the sequester device 405, 706. The centrifuge cover 625,704 connected to the sequester device 405,706 may, for example, form a cylindrical structure.

Alternatively, the one or more extraction regions 606, the first extraction region and/or the second extraction region may comprise a plurality of extraction holes 637. The plurality of extraction holes 637 and/or each of the plurality of extraction holes 637 may be spaced apart and disposed within the one or more extraction regions 606. The plurality of extraction holes 637 may be spaced apart and axially aligned. The plurality of extraction holes 637 may be spaced apart and offset. However, the activity indicator 621 may be, for example, shaped and colored to bring visual attention to the extraction region 606. During centrifugation, the centrifuge container 610 and/or the sequester wheel 405,706 spins, also spinning the activity indicator 621. The activity indicator 621 may, for example, provide a visual indication that the centrifuge is spinning and that the protective cover 601 should remain on until the centrifugation process is complete.

There may be more than two extraction regions 606. The multiple instances of extraction region 606, the extraction holes 637, and multiple instances of the activity indicator 621 may, for example, be positioned to minimize vibration and balance rotation of the centrifuge container. A plurality of extraction regions (e.g. multiple instances of extraction region 606) may be on the top surface 631 of the centrifuge cover 625 and, for example, radially approximately equally spaced and in approximately equal intervals on the top surface 631 to minimize vibration and to maintain balanced rotation of the centrifuge container 610.

The pathogen reduction agents or germicidal agents may comprise alcohols, chlorine dioxide, chlorine mixtures, formaldehyde, glutaraldehyde, hydrogen peroxide, Iodophor mixtures, peracetic acid, phenolic mixtures, quaternary ammonium mixtures, amotosalen or riboflavin, and/or any combination thereof. The pathogen reduction agents may be used alone and/or with combination of a UV light for enhanced pathogen reduction. The pathogens in whole blood or its blood components are inactivated by adding pathogen reducing agent and irradiating with UV light over a period of time, the period of time ranging from 5 to 90 minutes. This method reduces the infection levels of disease-causing agents by releasing active oxygen which damages the cell membrane of the pathogens and prevents replication of the carrier pathogens that may be found in whole blood or blood components for safer injection or transfusion. Pathogens may include viruses, bacteria, parasites, and/or white blood cells.

For example, in one embodiment, at least a portion of the container cover 625,704 and/or at least a portion of the protective cover 601,702 comprises a coating and at least one light. The coating includes germicidal agent, the germicidal agent is riboflavin. The at least one light includes a UV light, the UV light having a wavelength.

The rim 624,728 forms an opening 632,726 extending to the bottom side 633 of the top surface 631,724, with the rim 624,728 and an interior of the sidewall 628,736 surrounding the opening 632,726. The bottom surface 633,732 is opposite the top surface 631,724. The sequester device 405,706 is inserted into the opening 632,726, with rim 624,728 connected to rim 415, and forming the centrifuge container 610. The sequester device 405,706 and the centrifuge cover 625,704 may be, for example, connected so that the connection and/or coupling between rim 624,728 and rim 415 is sealed and liquid impermeable. The centrifuge cover 625,704 is disposed onto the sequester device 405,706 to create a liquid impermeable seal. Accordingly, the opening or recess 632,726 is sized and configured to match or substantially match an outer diameter of the first ring 416 of the sequester wheel 405,706, the outer diameter of the base plate 722 and/or an inner surface of the rim 415 of the sequester wheel 405,706. Alternatively, a rubber seal may be disposed between the rim 624,728 of the centrifuge cover 625,704 and the rim 415 of the base ring to create a liquid impermeable seal.

Referring to FIGS. 96 and 97, the centrifuge cover 625,704 may comprise one or more extraction regions 606, a first extraction region and/or a second extraction region. The one or more extraction regions 606, a first extraction region and/or a second extraction region comprises a seal or an extraction barrier 643, The seal or extraction barrier 643 comprises a plurality of extraction holes 637. There may be, for example, two instances of the extraction region 606, with the extraction holes 637 of the two regions being approximately opposite each other and approximately forming a diametric line. Two instances of seal 643 are shown, with each instance of extraction region 606 having the seal 643 positioned under the extraction holes 637, and positioned on the bottom surface 633 of the centrifuge cover 625,704. The seal 643 may be, for example, a circular or ovular membrane, fabricated from a plastic polymer material, and penetrable using a sharp object like, for example, a syringe (e.g. the syringe 699). The insertion opening 630 extends through the bottom surface. The insertion opening 630 may be unsealed. However, in other embodiments, the insertion opening may be sealed using a circular or ovular membrane, fabricated from a plastic polymer material, and penetrable using a sharp object like, for example, a syringe (e.g. the syringe 699).

With reference to FIGS. 98-99, 106, 107A-107B, 108A-108C, 109A-109B, the portable centrifuge 600,700 comprises a base 708, 730, the base 708,730 may comprise a rotational mechanism 650. The rotational mechanism 650 includes an activation slider 653 having an activation slot 651, and an arm 652. The activation slot 651 may be, for example, positioned under the activation slot 107 and is configured (e.g. shaped and dimensioned) to engage with the activation tab 608. The activation slot 651 is shown as at least one recess into which the activation tab 608 is insertable. By inserting activation tab 608 into activation slot 651 and rotating the protective cover 601, the activation slider 653 may be, for example, moved to make contact with the circuit member 159 and complete a circuit to activate the centrifuge.

The portable centrifuge 600,700 comprises a base 708, 730, the base 708,730 may comprise a motor 154. The motor 154 may be held in position or secured by a motor support wall 654. The support wall 654 may, for example, extend away from the baseplate 101 in an approximately perpendicular direction. The motor 154 is shown on the baseplate with the armature 161 extending out from the motor 154. The motor 154 may be, for example, positioned between two opposing sections of the support wall 654, such that the motor 154 is supported on two opposing sides.

In one embodiment, the base 708,730 of the portable centrifuge 600 may comprise at least one light or a plurality of lights 655. A light 655 may be, for example, positioned near or adjacent to the motor 154. Light 655 may be a single light source or a plurality of light sources. The light 655 may comprise a compact fluorescent lamp (CFL), an incandescent bulb, a halogen bulb, a light emitting diode (LED) bulb and/or an ultra-violet (UV) light. The light may be used as a visual indicator to inform the user of a started or completed centrifugation cycle, used to illuminate or provide a back light to the separated blood products for easier constituent selection and extraction. The UV light may also be used as a chemical free, highly effective disinfectant against harmful microorganisms. UV light includes a specific range of wavelengths within the UV-A, UV-B, or UV-C range that are categorized as germicidal—meaning they are capable of inactivating microorganisms, such as bacteria, viruses and protozoa (see FIGS. 105A-105B). In one embodiment, the wavelength comprises a range of 100 to 450 nanometers; the wavelength comprises 100 to 300 nanometers; the wavelength comprises 200 to 300 nanometers and specifically, the range may comprise 222 to 280 nanometers, the range may comprise 250 to 280 nanometers, the range may comprise 315 to 400 nanometers. Alternatively, the wavelength comprises 264 nanometers. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting. However, other light bulbs or similar light sources may be used. The light 655 may be connected to the motor support wall 654 and if there is a plurality of lights, the lights may be on opposite sides of the motor 154. In alternate embodiments, the light 655 may be positioned on a stand or a support extending out from the baseplate 101.

Accordingly, the base 708,730 may comprise a first light and a second light. The first light is different than the second light. The first and/or second light may comprise different color lights, different wavelengths, different bulb watts or different bulb sizes or diameters, different bulb types, different bulb types, different bulb intensities. For example, the first light being a violet colored LED bulb for a first visual indicator for activating the centrifugation process, the second light being a while colored LED bulb for a second visual indicator when the centrifugation cycle is complete. Another example includes a first light being an LED bulb type and the second light being a UV bulb type. Alternatively, the base 708,730 may comprise a first light, a second light and a third light. Each of the first, second and third lights are different from each other.

In another embodiment, the protective cover 601,704 and/or the container cover 625,702 may comprise at least one light 655. The at least one light 655 may be disposed onto an internal circumference sidewall 618 of the protective cover 601, 704 and/or the external sidewall 627,734 of the container cover or activation cover 103, 625, 702. The at least one light 655 may be disposed onto the top surface of the protective cover 601, 704 and/or the container cover 103, 625,702. Alternatively, the Accordingly, the protective cover 601,704 and/or the container cover 103, 625 may comprise a first light and a second light. The first light is different than the second light. The first and/or second light may comprise different color lights, different wavelengths, different bulb watts or different bulb sizes or diameters, different bulb types, different bulb types, different bulb intensities. For example, the first light being a violet colored LED bulb for a first visual indicator for activating the centrifugation process, the second light being a while colored LED bulb for a second visual indicator when the centrifugation cycle is complete. Another example includes a first light being an LED bulb type and the second light being a UV bulb type. Alternatively, the protective cover 601,704 and/or the container cover 103,625,702 may comprise a first light, a second light and a third light. Each of the first, second and third lights are different from each other.

In still further embodiments, the base 708,730 may comprise a base cover 102. The base cover 102 may have supports to secure the light 655. The light 655 may be, for example, positioned to shine light through the base cover opening 657. The armature 161 may be, for example, engaged with the armature hub 422 of the sequester device 405, and positioning the light 655 close to the motor 154 provides for light transmission into the centrifuge container 610. The centrifuge cover 625,702 and the sequester device 405,706 may, for example, be fabricated from a clear polymer plastic material or a material through which blood separation columns may be visible and through which emissions from the light 655 may be visible. The light 655 may, for example, be connected to a timer on the circuit board 151 which activates the light 655 when the centrifugation process is complete. The light 655 may display as continuously (e.g., “always on”) and/or it may be flashing, which flashing delivers quick bursts of light over a period of time.

Continuing with FIGS. 98-99, 106, 107A-107B, 108A-108C, 109A-109B, the light 655 may comprise different colors for different functions. The colors include different color frequencies provided for different centrifugation applications. For blood separation, a white light may, for example, be used to more easily see and identify the blood concentration spectrum in the various channels (e.g. the first channel 440, the second channel 441, and the third channel 442). For example, a red or blue light may be more suitable for other applications. In still other centrifugation applications lighting may be used to identify tracer materials in the blood such as, for example, a black-light (lighting devices emitting ultraviolet frequencies) used to identify a phosphorous tracer.

With reference to FIGS. 100 and 101, the activation slot 107 is an elongated opening through the base cover 102 configured (e.g. shaped and dimensioned) to admit the activation tab 608. The activation slot 107 has an arm 641 within the activation slot 107 extending from a first end 646 connected to the base cover 102, towards a free second end 647. The arm 641 has a lock 645 shown as a triangular protrusion from the arm 641. A first side 648 of the arm 641 may have, for example, a sloped section 642 followed by a ledge 644 towards arm 641, forming the lock 645. The ledge 644 may be, for example, curved or approximately perpendicular extending from the first side 648 to meet the sloped section 642. The activation tab 608 may be, for example, moved within the activation slot 107 sliding along arm 641. However, once the activation tab passes the lock 645, the activation tab 608 may continue moving in the original direction to towards the free second end 647, but be prevented from moving back past the lock 645 towards the first end 646. By moving the activation tab 608 along the first side 648 of arm 641, the arm 641 and the lock 645 are bent away from the activation tab 608 as the activation tab 608 moves along the sloped section 642. Once the activation tab 608 has passed the ledge 644, the arm 641 snaps back or unbends, positioning the lock 645 behind activation tab 608 and returning arm 641 to an approximate original position.

The portable centrifuge 600,700 may comprise a base 708,730, the base comprises a lock 654. The lock 654 may, for example, prevent the centrifuge 600 from being reactivated while the centrifuge container 610 is still spinning. The centrifugation process is timed, and reactivation may cause delays or may damage blood cells through repeated centrifugation.

With reference to FIGS. 91-99, 106, 107A-107B, 108A-108C, 109A-109B, the rotational mechanism 650 and baseplate 101 are covered by the base cover 102. The armature 161 may be approximately centered within the base cover opening 657 for engagement with the armature hub 422 of the centrifuge container 610. The centrifuge container 610 and/or the sequester wheel 405,706 may be, rotatably engaged with the armature 161, with the centrifuge container 610 and/or the sequester wheel 405,706 positioned over the motor 154 and concentric with a rotational axis of the motor armature 161. The protective cover 601,702 may be, for example, positioned over the centrifuge container 610 and/or the sequester wheel 405,706, with the activation tab 608 inserted into the activation slot 107 and into the activation slider slot 651. The insertion barrier 619 may be, for example, positioned above the insertion tube 629 and covering the opening 609 of insertion tube 613.

The portable centrifuge 600,700 may comprise a base 708,730, the base 708,730 comprises a brake 607. The brake 607 may be, for example, engaged to stop rotation of centrifuge container 610 and/or the sequester wheel 405,706 after the rotational mechanism 650 has been turned off. The brake comprises a brake pad 612. The brake pad 612 wedge shape may be, for example, configured (e.g. shaped and dimensioned) to match the conical slope of the top surface 631. Depressing the brake button 607 may, for example, push brake pad 612 against the top surface 631, frictionally slowing the centrifugal container. The brake 607 is movable from a first position to a second position, the first position comprising the brake pad 612 having no contact with the sequester device, and a second position comprising the brake pad 612 contacting or engaging the sequester device to slow the revolutions per minute (RPM) to a complete stop via friction.

With reference to FIGS. 91-99, a method of use for a portable centrifuge 600, 700 may include extracting blood from a patient using a syringe (e.g. the syringe 600), inserting the syringe cannula into the opening 609 of the insertion tube 613 and piercing the seal 619 to insert the cannula into the opening 630 of tube 629, and depressing the plunger to introduce blood into a portion of the centrifuge container 610 and/or a portion of the sequester wheel 405, 706. Furthermore, the centrifuge 600 may be in close proximity to the patient and may remain within a sterile environment. Grasping at least two finger holds 605, rotating the protective cover, moving the activation tab positioned within the activation slot past the lock 645, connecting the activation slider 653 with the circuit members 159, completing the circuit, activating a timer, activating the motor 154, and spinning the centrifuge container 610. Observing the activity indicator 621 to confirm that the centrifuge container 610 is spinning. Reaching a threshold time, the light 655 is activated and power is stopped to the motor 154. Depressing the brake 607 to frictionally slow and stop the spin of the centrifuge container 610. Observing the activity indicators 621 to determine if the centrifuge container 610 has stopped. Removing the protective cover 601. Observing the desired blood composition. Inserting a syringe cannula into a desired extraction hole 637. Pulling a syringe plunger to remove a desired blood constituent through the cannula and into the syringe. Removing the syringe.

For centrifuges 100, 400, 500, and 600, the positioning of extraction holes (e.g. 121, 407, and 637) and extraction barriers (e.g. 443 and 643) may be to, for example, minimize vibrations and help balance centrifuge container rotation. In addition, activity indicator 621 may be applied to centrifuges 100, 400, 500, and 600 around the extraction holes (e.g. 121, 407, and 637) to form an extraction region.

Referring to FIGS. 1, 2, 36, 37, and 44, another alternate embodiment of centrifuge 500 is shown. As centrifuges 100, 300, and 400 have been described in detail, above, for the sake of brevity, similar components will not be further described herein. The centrifuge 500 has the centrifuge motor or rotational mechanism 330 on the baseplate 101 and enclosed in the base cover 102. The centrifuge 500 further has the protective cover 103 and a centrifuge container 530, with the centrifuge cover 104 and a baseplate 506. The baseplate 506 may be, for example, of similar structure to the baseplate 106, however baseplate 506 has a solid top surface 536. The baseplate 506 has the base motor connector 120 and the protrusion 126 and may be, for example, circular or cylindrical.

With continued reference to FIG. 44 the centrifuge cover 104 may be, for example, placed onto the baseplate 106 and sealed creating a liquid impermeable connection. A thixotropic separation gel and an anti-coagulant may be introduced to the centrifuge container 530, for example, prior to being sealed, forming a thin layer on the baseplate top surface 536 or along the interior surface of the sidewall 137. Polymer barriers may be used to, for example, seal openings in the centrifuge cover 104 (e.g. the plurality of extraction holes 121 and the at least one insertion hole 122). In another aspect of the centrifuge 500, the centrifuge container 530 may be sealed and empty, with the separation gel and anti-coagulant added through the insertion hole 122 to the centrifuge container 530 just prior to introducing the blood sample.

Referring to FIGS. 16, 44, and 64B, centrifuge container 530 may be, for example, connected to the motor 154, with the motor armature 161, the base motor connector 120, the baseplate 506, and the protrusion 126 connected for coaxial alignment and rotation about a common axis 565. The protective cover 103 may be placed over the centrifuge container 530, with the activation tab 108 inserted through the activation slot 107 and into the activation slider slot 156. While the axle 126 is shown, there may be aspects of the centrifuge 500 that do not have the axle 126.

With reference to FIGS. 1, 2, 14, 44, 64B, and 88, a method of use for centrifuge 500 may include removing the protective cover 570 and introducing blood into the centrifuge container 571. Blood may be introduced into the centrifuge container 530 through, for example, the insertion hole 122 into the centrifuge container 530, using for example, a syringe (not shown). Replacing the protective cover 103, the activation tab 108 is inserted through the activation slot 107 and into the activation slider slot 156. The protective cover may be turned to activate the centrifuge 573 and the centrifuge container may rotate 574. The blood may interact with the thixotropic gel and the anti-coagulant 575 and may separate into constituent components 576. Turning the protective cap 103, causes the activation tab 108 to move the sliding switch 157 so that the conductive member 158 contacts the circuit members 159 and creates a closed circuit. The electric motor 154 spins the centrifuge container 530. The separation gel may, for example, interact with the RBCs, creating a barrier for RBCs, while the anti-coagulant may, for example, inhibit PRP and PPP from coagulating. A timer may send a stop signal to the motor 577 and the centrifuge container may stop rotation 578. The timer on the circuit board 151 opens the circuit after a threshold time is reached, and the rotation of the centrifuge container 530 continues, slowing to a stop. The protective cover 103 may be removed 579. The use of a separation gel and an anti-coagulant creates distinguishable separation of the blood constituents (e.g., RBC, PRP, and PPP). PRP is generally in a gradient of concentrations between a PPP constituent volume and the PRP constituent volume, allowing extraction of a desired PRP concentration. The blood constituent components may be removed 580. The RBC, PRP, and/or PPP may then, for example, be removed using the plurality of extraction holes 121 by inserting a sharp object, such as, for example, a syringe (not shown).

In other aspects of the centrifuges 300, 400, 500, the rotational mechanism 110 may be used instead of rotational mechanism 330. If rotational mechanism 110 is use with centrifuges 300, 400, and 500, the solenoid 153 and thus solenoid armature 163 may be used to provide braking by triggering and extending the solenoid armature 163 to make contact with the rotor 312 or centrifuge container 430 or 330.

The protective cover 103 for the centrifuges 100, 400, and 500 is shown as clockwise twistable in FIGS. 1 and 74, however the specific configuration of the internal components of the rotational mechanisms (e.g., 110 and 330) may be changed to provide for counter-clockwise activation. Furthermore, one skilled in the art would understand that other activation methods that close a circuit may be used in place of activation by twisting the protective cover 103.

With reference to FIGS. 75-82, the brake 401 is shown and described as part of the protective cover 403 and centrifuge 400. However, the centrifuges 100 and 500 may have, for example, the protective cover 103 with brake 401. Furthermore, protective cover 403 may be, for example, sized and dimensioned for use with centrifuges 100 and 500.

With reference to FIG. 86, the extraction barrier 443 is shown covering the plurality of extraction holes 407 of the centrifuge 400. The extraction barriers 443 are shown as being on the bottom side 435 of centrifuge cover 404. In other aspects, the extraction barriers 443 may, for example, be positioned on the top side 436 of centrifuge cover. In other aspects, centrifuge 100 and centrifuge 500 may have, for example, the extraction barrier 443 on the centrifuge cover 104, with the extraction barrier 443 on either the top side 136 or the bottom side 135. For still other aspects of centrifuges 100, 400, and 500, the extraction barrier 443 may be a single barrier covering the plurality of extraction holes 121, 407 and the insertion hole 402, 122 or the extraction barrier 443 may be a plurality of individual barriers for each of the plurality of extraction holes 121, 407 and insertion holes 402, 122.

With reference to FIGS. 1-86, the centrifuges (e.g., 100, 300, 400, 500) may be, for example sealed and sterilized prior to use, and may be delivered in a sealed container or packaging. The centrifuges (e.g., 100, 300, 400, 500) are also sized to be portable. The centrifuges (e.g., 100, 300, 400, 500) are self-powered, having an internal power supply (e.g., at least one battery 155) that does not have external cords or cables or require an external power supply (i.e. an electrical outlet or a generator). The combination of being sealed, sterilized, and portable with at least one internal battery, provides centrifuges (e.g., 100, 300, 400, 500) that may be opened in a sterile environment and made available for use in the sterile environment (e.g., a surgical operating room). This obviates the need for leaving the sterile environment to obtain blood separation. The centrifuges (e.g., 100, 300, 400, 500) may, for example, also be single use devices, disposable or recyclable after each use and minimizing blood handling or exposure. Further, the centrifuges (e.g., 100, 300, 400, 500) may be part of a sealed and sterilized kit including, for example, a syringe and/or hypodermic needle for insertion and extraction of the blood, bone marrow, or tissue.

Microfluidic Portable Centrifuge

Hemostatic disorders are both complex and costly in relation to both their treatment and subsequent management. There is an ever-increasing drive to improve the diagnosis and prevention of hemostatic disorders because traditional diagnostic methods contain various disadvantages. Various tests and devices have been developed over many decades to assess blood clotting and platelet function in-vitro, including assays for bleeding time, activated clotting time (ACT), activated partial thromboplastin time (aPTT), thromboelastography and platelet aggregometry.

While these traditional tests provide useful information regarding coagulation status or platelet function, they are limited in terms of their ability to predict thrombotic or bleeding risk in clinical settings at least in part because they fail to incorporate many of the key contributors to hemostasis control that exist in-vivo. For example, a major limitation of these assays is that they require extraction of large or exact volumes of blood by venipuncture and measure clotting behavior under static (no flow) or irrelevant flow conditions, and thus, they fail to incorporate the effects of hemodynamic forces (pressure, flow and shear stress) and related cellular interactions that are known to significantly impact whole blood thrombosis in the living vasculature. Notably, flow acceleration and deceleration (fluid shear gradients) have been shown to initiate platelet aggregation during arterial thrombosis in-vivo and clotting in extracorporeal devices usually occurs at sites of sudden flow disturbances, stagnation points and stenosed sections of tubing. However, none of the routinely used hemostasis assays incorporate these physiological conditions in their assessment of blood coagulation, as well as require expert/experienced personnel to perform the process and interpret the results.

As a result, point-of-care (POC) or similarly named nearly-patient-testing (NPT) is playing more of an important role in hemostasis diagnostic settings. A need remains to create or manufacture a detection method and apparatus for POC and/or NPT clotting time determination. The detection method and apparatus may comprise smaller and/or unmeasured whole blood samples, in the microliter scale, for rapid determination of clot-time while the whole blood is being centrifuged into its constituent components. Furthermore, such a detection method and apparatus can be used to determine the relative clotting/coagulation potential at the time of use, prophylactic actions could be taken to adjust the patients' medical treatment(s) to improve their healing potential. This can also be used as a relative research tool because doctors usually do not know how active the platelets are and if they have this knowledge, they could adjust other surgical interventions knowing how viable the platelets were at the time of use.

In one embodiment, the portable centrifuge comprises a microfluidic mechanism for POC, NPT or real-time monitoring of hemostasis that permits rapid determination of clotting time for whole blood as its perfused through at least one fluid channel (hereinafter the “microfluidic centrifuge). In another embodiment, the portable centrifuge comprises a microfluidic mechanism for POC, NPT or real-time monitoring of hemostasis that permits rapid determination of clotting time for whole blood as its perfused through at least one fluid channel (hereinafter the “microfluidic centrifuge) and/or perform centrifugation of whole blood into its constituent components. The microfluidic centrifuge may further comprise a plurality of fluid channels that mimics local physiologic relevant changes in hemodynamic flow conditions experienced in living stenosed arterioles.

Microfluidic mechanisms offer several benefits over conventional detection methods. Microfluidic mechanisms exploit the physical and chemical properties of liquids and gases at a microscale, and allow the analysis and use of less volume of samples, chemicals and reagents reducing the global fees for analysis. Many microfluidic mechanisms can be executed at the same time due to their compact size, while shortening the time of experiment. They also offer an excellent data quality and substantial parameter control which allows process automation while preserving its performance. The microfluidic chip allows the user to generate multi-step analysis requiring low level of expertise and a lot of functionalities.

In another embodiment, the microfluidic centrifuge (or portable centrifuge with microfluidic mechanism) could determine coagulation by whole blood flowing into the at least one fluid channel via capillary action or flow pressure. Upon entry of the whole blood into the at least one channel would yield a relative clotting potential based on time and differential pressure induced by the portable centrifuge. The relative clotting/coagulation potential would be measured and/or calibrated against laboratory settings to initially determine its accuracy.

With reference to FIGS. 113A-113B, another embodiment of a portable centrifuge 738,744 is shown. The portable centrifuge 738,744 comprises a protective cover (not shown), a container cover 740,746 and a sequester wheel or sequester device (not shown), and a base 742. The base 742 comprises a rotational mechanism (not shown), a base plate (not shown), and a base cover (not shown). The protective cover, the container cover, the sequester device, the base, rotational mechanism, base plate, base cover, and the protective cover has already been described in detail in the above paragraphs, and for the sake of brevity, will not be further described, unless new features are identified below. The portable centrifuge 738,744 may further comprise at least one coagulation module 760 with a microfluidic mechanism 762.

In another embodiment, the portable centrifuge 738, 744 comprises a plurality of coagulation modules 760 (for spinning balance) to determine coagulation or clot-time as shown in FIG. 113B. The plurality of coagulation modules 760 disposed onto the container cover with at least one of the blood communication ports 766a, 766b to the outer radius of the sequester wheel. Alternatively, the at least one blood communication port 766a, 766b may be proximate to the central axis 830 of the sequester wheel. Because the pressure increases from the central axis 830 of the sequester wheel to the outside radius or perimeter of the sequester wheel, the differential pressure would push, force, direct and/or drive the initial blood or fluid portion through inlet 766a and then through the micro-fluidic chamber 762 of at least one of the plurality of coagulation modules 760 resulting in a first fluid transport direction away or outwards from the central axis 830 to the outer perimeter of the sequester wheel or portable centrifuge. Instead of using capillary action in most technologies, the blood and/or fluid is pushed, directed or forced via differential pressure through the microfluidic chamber 762 resulting in a second fluid or blood transport direction inward towards the central axis 830. At some point during this flow, the blood or fluid would clot or coagulate in the microfluidic chamber 762 to provide a relative coagulation potential. The centrifugal force becomes less inwardly providing an extended blood or fluid path and increased accuracy as the blood starts to thicken. Ultimately, the first fluid transport direction is different or opposite of the second fluid transport direction. Also, clotting indicators 764a, 764b, 754c could be established for acceptable results.

Two-stage aliquoting allows the fluid to be first metered and split into sub-volumes, then forwarded to the one or more receiving chambers 800. The two-stage is desirable when independent metering is required, cross contamination is an issue, or when further fluidic processing of the individual aliquots is required. Two-stage aliquoting combines the parallel metering of one-step aliquoting with normally closed valves at the radial outer side of each metering finger. After metering, the single aliquots can pass the valve and be used for further fluidic processing. The basic principle of the aliquoting processing allows the fluid to be introduced via centrifugation of the portable centrifuge via capillary flow, centrifugal flow, and/or differential pressure flow 836 into the one or more aliquoting mechanisms 796. The one or more aliquoting mechanisms 796 are sloping or substantially sloping.

The valve may be movable from a first position to a second position, the first position comprises a “closed” position prevent fluid flow or blood flow, and the second position is the “open” position to allow fluid flow or blood flow. To pass or open the one or more valves, the forces or pressure has to exceed the counter pressure exhibited by the one or more valves. The one or more valves may be disposed at the inlet and/or the outlet. The one or more valves may be disposed between the inlet and the outlet, and/or the one or more valves may be disposed anywhere along the length of the at least microfluidic mechanism 780.

MSCs or stromal cells can be isolated from different tissues, which include adipose tissue, tendons, periodontal ligament, synovial membranes, trabecular bone, bone marrow, embryonic tissue, the nervous system, skin, periosteum, muscle, peripheral blood, and/or any combination thereof. Accordingly, MNCs can be isolated from tissues, including bone marrow, umbilical cord, peripheral blood, and/or spleen. Furthermore, SVF is a heterogenous mixture of cells isolated by enzymatic or non-enzymatic dissociation of the lipoaspirate obtained from liposuction of excess adipose tissue that contains a large population of adipose derived stem cells (ADSCs), and other types of cells (e.g., endothelial cells, erythrocytes, fibroblasts, lymphocytes, monocytes, pericytes, etc.).

In another embodiment, the portable centrifuge 896, 934 can isolate peripheral blood mononuclear cells (PBMCs) from peripheral blood and/or isolate stem cells from PBMCs. PBMCs are blood cells with round nuclei that encompass a heterogeneous cell population comprising various amounts of lymphocytes (T cells, B cells, and NK cells), dendritic cells, and monocytes. These cells are critical components of the innate and adaptive immune system which defends the body against viral, bacterial, and parasitic infection and destroys tumor cells and foreign substances. PBMCs can be isolated by density gradient centrifugation, as different components of the blood have different densities and can be separated accordingly allowing the portable centrifuge to operate at a constant rotational speed for set time based on the organelles sedimentation rate. Further processing known in the art may be used with the portable centrifuge and/or other techniques to facilitate isolation of stem cells, MSC's from the isolated MNCs.

In another embodiment, the portable centrifuge 896, 934 can isolate SVF from adipose tissue using enzymatic and/or non-enzymatic techniques and/or isolate stem cells from SVF. As described herein, SVF cells are obtained through liposuction and contain multiple cell types, including adipose-derived stem cells (ADSCs) with potential tissue regenerative activity. Upon isolation and processing, the adipose-derived SVF cells can differentiate into different tissue types, support neovascularization, replace cells and repair injured issue. Further processing known in the art may be used with the portable centrifuge and/or other techniques to facilitate isolation of stem cells, other cell types, and/or MSC's from the SVF.

In another embodiment, the portable centrifuge 896, 934 can isolate mononuclear cells (MNCs) and mesenchymal stem cells (MSCs) from bone marrow and/or stem cells from MNCs or MSCs. BM-MSC isolation procedures may use density centrifugation with a density medium to separate the mononuclear cell (MNC) fraction from the other marrow constituents (i.e., red blood cells, plasma, lipids). This MNC fraction contains an enriched population of T-cells, B-cells, monocytes, hemopoetic stem cells (HSCs), endothelial progenitor cells and MSCs. The BM-MSCs are further isolated via plating onto tissue culture flasks. BM-MSCs are an attractive therapeutic tool due to their potential to be differentiated into a variety of cell types and their immunosuppressive properties. Their application is being explored in cell transplantation, regenerative therapy, correcting genetic disorders, diseases, and tissue engineering. Further processing known in the art may be used with the portable centrifuge and/or other techniques to facilitate isolation of stem cells and/or other cell types.
