Description
- This application claims priority to U.S. Provisional Patent Application Ser. No. 62/533,323, filed Jul. 17, 2017 and entitled, which is hereby incorporated herein by reference in its entirety.
- This invention was made with government support under Contract R44DK108689, awarded by the National Institute Of Diabetes And Digestive And Kidney Diseases of the National Institutes of Health. The government has certain rights in the invention.
- The disclosed technology relates generally to preparing and/or shipping biological samples collected in any environment, and in particular, to the devices, methods, and design principles allowing the efficient preparation and shipping of bodily fluid samples.
- The disclosure relates to apparatus, systems and methods for preparing and shipping bodily fluid samples collected in any environment, including non-clinical environments. While analysis laboratories are well suited to perform diagnostic tests, the collection of bodily fluid samples remains challenging, in particular for patients that do not have easy access to a suitable laboratory.
- Devices, systems and methods to collect bodily fluids are necessary devices for the growing field of personalized medicine. As point-of-care devices continue to improve, an often overlooked area lies within the collection of samples from untrained users. Currently, biological samples are most commonly obtained via either simple-to-use methods or devices, as with generic lancing devices, or trained personnel, as with phlebotomy venipunctures. In order to transfer the bodily fluid to a container, receptacle, or an analysis device, multiple steps are required that are time consuming, error prone and/or cumbersome.
- Patients without easy access can be located in rural areas, underserved urban and sub-urban areas, low resource areas, or generally do not have time or means to visit a laboratory, creating significant barriers to accessing diagnostic services. In order to reach patients in all locations, and connect them with suitable laboratories, robust systems for bodily fluid sample acquisition, stabilization, and shipping are required.
- Thus, there is a need in the art for improved bodily fluid collection devices that can be self-applied at the convenience of the patient and utilize simple, cost-effective methods to handle bodily fluid samples, prepare and stabilize samples for transportation, and allow the robust transport to an analysis laboratory. More specifically, there is a need for simple and robust methods and devices to extract components of a blood sample, add reagents to the samples, and package the sample for safe and reliable transport. The disclosed methods and devices are simple to operate in any environment without additional equipment and/or any specific training.
- Thus, there is a need in the art for improved apparatus, systems, and methods for bodily fluid sample preparation.

- Turning to the drawings in greater detail,
FIG. 1A andFIG. 1B depict exemplary implementations of the preparation and transportation/shipping device, orcentrifuge system 10. According to the implementations ofFIG. 1A andFIG. 1B , thecentrifuge system 10 generally has ahousing 12 containing acentrifuge frame 16 supporting arotor 24, which are covered by alid 20. - In these and other implementations, the
rotor 24 has at least oneopening 26 constructed and arranged to accept a biological sample (such as in a sample tube discussed below at 36) for centrifugation and transport. As such, it is understood that simple usability has been contemplated in the design to make the device andcentrifuge system 10 as easy-to-operate as possible enabling use of thesystem 10 in the home, basic clinic, field, and/or retail settings. - It is understood that the
rotor 24 contains the biological sample(s) and spins at a defined RPM to perform separation of subcomponents of a sample. As shown in the implementations ofFIG. 2A andFIG. 2B , therotor 24 can contain configurations that allow for either manual or automatic closing of a sealed compartment to house the biological sample after the user places the sample into therotor 24. - In the implementations of
FIG. 1A andFIG. 1B , thesystem 10 has a covering 18 on the rotor (FIG. 1A at 24) that can be removed to activate thecentrifuge 16. In use according to other embodiments described in relation toFIG. 1C andFIG. 1D , the opening of thelid 20 can activate thecentrifuge 16 without the covering. It is understood that enabling the automatic activation of thecentrifuge 16 via the opening of thelid 20 and/or cover 18 would be achievable through a variety of structural configurations readily appreciated by those of skill in the art. In the implementations ofFIG. 1A andFIG. 1B , thelid 20 has atab 22. - According to these implementations, after a
sample 26 is processed and is ready to be transported and/or shipped for analysis, thetab 22 can be affixed to thedevice housing 12 with adhesive 14 to prevent thecentrifuge 16 from being re-opened. In various implementations, the adhesive 14 is single usage tape. It is understood that in other embodiments, thelid 22 can be closed with other methods or mechanisms known in the art. - The
centrifuge system 10 according to these implementations has been constructed and arranged to meet or exceed the requirements of shipping and/or transporting biological samples, in particular to achieve a compact size, low cost, disposal of elements that may be contaminated by biological samples, and include all necessary components to meet the regulations of biological sample transportation set forth in UN Recommendation 3733 and International Air Transport Association Rule 3.6.2. - Continuing with the drawings,
FIG. 1A shows an implementation of thecentrifuge system 10 with therotor 24, with the protective covering removed (shown inFIG. 1B at 18), such that therotor 24 is exposed for sample insertion. In this implementation, therotor 24 comprises anopening 26 that is constructed and arranged to accept the sample for centrifugation. -
FIG. 1C andFIG. 1D depict an implementation of thesystem 10 having adetachable lid 20. In these implementations, thelid 20 is secured within thehousing 12 when not in use, as would be understood. It is further understood that in various implementations, thehousing 12 andlid 20 are foam or other thermodynamically favorable materials such as polystyrene (EPS). - As shown in the implementation of
FIGS. 1C and 1D , thehousing 12 contains arotor 24 disposed within acavity 24A at the base of thecentrifuge frame 16. As described in relation toFIG. 1D , thecentrifuge frame 16 containsopenings PCBs 28,batteries 33, switches 19, 21 and amotor 25. In various implementations, theframe 16 is made of plastic or other light and rigid materials understood such as metals, polymers or composites. - In certain implementations, the
lid 20 may serve as the only covering, whereas in alternate implementations like that ofFIG. 1A andFIG. 1C , anadditional covering 18 may be constructed and arranged to cover thecentrifuge 16 and therotor 24. - In the implementation of
FIG. 1C , thecover 18 has acover opening 18A. In use according to these implementations, thecover opening 18A is constructed and arranged to accommodate direct passage of a biological specimen into arotor opening 26 which is in turn constructed and arranged to accept a biological specimen for centrifugation.FIG. 1C andFIG. 1D further show acounterbalance 26A disposed opposite the opening on the rotor, as would be understood by those of skill in the art. - In exemplary embodiments, the biological specimen can be in a container such as a
HemoLink tube 36 from the user. In other embodiments, therotor opening 26 is constructed and arranged to accept a tube in only one direction, ensuring correct processing of the sample. It is understood that many configurations are possible. - It is understood that these implementations of the
cover opening 18A androtor opening 26 are constructed and arranged so as to allow for the ease of use, that is, passage of the biological specimen into therotor 24 for use. It will be appreciated that thecover 18 can be constructed from any number of materials, some non-limiting examples being plastic, Tyvek® and carboard. - As the centrifuge may be re-utilized it is beneficial to discard any part that may have come in contact with biological samples. A possible embodiment is to place the electronics and re-useable parts on a frame made of metal or hard plastic. The outer parts of the centrifuge can be made of easily discardable materials, such as cardboard. These parts would mostly be used to shield the electronics from sample spills as well as improve the usability of the device by hiding undesirable elements.
- Various implementations of the
system 10 are constructed and arranged to have automated actuation and safety stop features. In these implementations, the centrifugation process must be started only when the sample has been placed in the rotor without requiring the operation of any manual switch. In one embodiment a switch that is actuated when the lid is closed that can initiate the centrifugation process as well as operate as a safety switch. In these implementations, the switch must be protected from being actuated during shipping such that the centrifuge will only operate after the user places the sample in the rotor. - Continuing with the implementation of
FIG. 1C , in this implementation a kill or lockingswitch 19 andactivation switch 21 are provided. In these implementations, the lockingswitch 19 is constructed and arranged so as to prevent the operation of the centrifuge during transportation. In exemplary implementations, the lockingswitch 19 prevents activation of the centrifuge via a stored tube or tube cap (such as that described below in relation toFIG. 2C ) in the lockingswitch 19 opening, as would be understood. In alternate implementations, the lockingpin 19 can be activated/deactivated via an aligned pin that extends into an opening activating the lockingswitch 19 or other components and approaches understood in the art. - The lid is designed to interface with the frame and actuate switches to start or stop the process. The lid must have sufficient rigidity to avoid coming in contact with the spinning rotor. In use according to these implementations, when the user removes the
tube 36 or tube cap from the lockingswitch 19 opening, the lockingswitch 19 is disabled. Subsequently, when the lid is returned to the closed position, theactivation switch 21 is able to start thecentrifuge 16, such as via a magnet disposed within thelid 20 that is constructed and arranged to activate theswitch 21 and initiate centrifugation. - In the implementations, the
switches frame 16 and in operational communication with therotor 24. That is, therotor 24 is in operational communication with amotor 25 disposed within thehousing 12, as well as with a printed circuit board (PCB) 28 via aPCB mount 29 andmotor mount 31. In various implementations, thePCB 28 is constructed and arranged to operate and control of the timing and speed of thecentrifuge rotor 24. - In various implementations, such as that of
FIG. 1D , the centrifuge can be powered by abattery 33 and/or be plugged in to a power source. - Further, the PCB (or other microcontroller) 28 of these implementations is in operational communication with the
switches first cavity 37 defined within the frame. - Continuing with the
switches system 10 can be programmed such that theactivation switch 21 initiates a timer on thePCB 28 or other control component to ensure that the sample has sufficient time to absorb reagent, clot, come to a specified temperature and/or meet some other condition or criteria understood by the skilled artisan. - That is, many different types of blood-related samples can be needed depending on the clinical analysis being performed. Typically, a centrifuge would have rotation speed controls and switches. In contrast, an aim of the
shippable centrifuge system 10 is simplicity, and as such can be pre-programmed for execution of a specified assay, such as that which would be based on a prescription. - In various implementations, the
PCB 28 or other microcontroller can be programmed to achieve a number of other objectives. For example, in order to ensure a quality sample upon reception, it is important to track the time at which the sample was acquired and the environment through which the sample was subjected. Accordingly, in certain implementations thePCB 28 or other microcontroller can be constructed and arranged to log time and temperature in order to reject samples that may have been subjected to out-of-specification conditions. - In various implementations of the
system 10, the electronic components such as thePCB 28 are constructed and arranged to allow thesystem 10 to test the power supply to ensure sufficient voltage for operation. Because the rotor speed will vary depending on the voltage, it is important to have an internal test of the power supply onboard the shippable sample preparation system or as an included part of the system. If the power supply has insufficient voltage, an advantage of the system is that the power supply can be recharged or removed and replaced. - The electronic components also allow for several safety and consistency features. For example, redundant batteries or other power sources can be provided within the
frame 16. That is a primarylarger capacity battery 33 can be provided to power therotor 24, and another smaller capacity battery disposed, for example, on thePCB 28 or elsewhere within theframe 16. This secondary battery (shown generally in the cavity at 37) can operate basic tasks with the onboard electronics/PCB 28. In certain implementations the larger capacity primary battery is a removable lithium ion battery or another battery with a larger capacity and density with a smaller footprint while the secondary battery is be a non-lithium ion battery to comply with shipping regulations. - Another safety feature within the device is to have a program or switch within the device that ensures the sample is only centrifuged at least and no more than one time. This means that if for some reason the centrifuge is interrupted mid-cycle, the centrifuge will be able to re-start to spin one time. If the device is opened after centrifugation is completed, it will not re-centrifuge the contents.
- In other embodiments, the shippable
sample preparation system 10 can contain wireless communication capabilities, such as but not limited to, NFC or Bluetooth® systems allowing for the transmission of data from the system to a user's smartphone device or a dedicated reader. In various implementations, these are disposed within theelectronics housing 37 and in operational communication with thebattery 33,PCB 28 and/or any other modules or processors and sensors necessary to perform the contemplated functions. - In certain implementations, the
system 10 is constructed and arranged to record information about the sample processing, such as the activation time, the duration of the processing, the centrifugation speed, as well as the shipping conditions through time. In various implementations, a data storage device such as memory or a drive (not shown) are provided to store data. Additional information on the success of the centrifugation, geolocalization of the sample when the system was actuated and through time can be recorded from sensors (not shown) interconnected with the PCB and/or other components, such as GPS sensors and the like. - In various implementations, recorded data can be transmitted to the user or laboratory to assess quality metrics or other statistics about the patient or sample. Reversibly, information can be transmitted to the shippable sample preparation system via wired or wireless connections, thereby allowing the storage of the list of analytes that will be measured on the sample, which can replace or complement a laboratory requisition form, as well as the sample preparation parameters, such as centrifugation time, speed, and the like. It is understood that a further suite of known electronic components can be stored within the frame and placed into operational communication with the
battery 33 and/or other electronic components so as to be constructed and arranged to effectuate the data collection and communication functions contemplated here. - As also shown in
FIG. 1D , in these implementations acavity 39 is disposed within the housing, which is constructed and arranged to hold a cooling element (FIG. 4B at 58), which is in thermodynamic communication with therotor 24 and sample. - As shown in
FIG. 2A , therotor 24 of this implementation has aremovable sample 32 constructed and arranged to fit within theopening 26. In this implementation, therotor 24 connects to the motor (as shown inFIG. 1D at 25) in the housing (inFIG. 1A at 12) via anaxle 30 disposed substantially at the center of therotor 24. - In the implementation of
FIG. 2B , therotor 24 shows an implementation of theopening 26 constructed and arranged to accept asample 32 housed in an optional additionalremovable container 34. It is understood that shipping liquid blood samples can require the use of a double-hulled container to prevent unwanted spillage. Certain implementations achieve this double-hulling by placing thesample 32 in a tube (primary container) 36 and having thesecondary container 34 be a small container holding the tube, or therotor 12 itself, or the box of the centrifuge. In various implementations, the secondary containment can be accomplished by having self-closing lids on the rotor actuated by the centrifugal forces or inertial forces that occur at the start or during centrifugation, as would be understood. - As shown in
FIG. 2C , in certain implementations, theremovable container 34 defines a lumen and contains atube 36 disposed therein, thetube 36 defining asample lumen 38. In these implementations, thecontainer 34 can be removed forsample 32 insertion, and can integrate atube cap 40 onto thelid 42 for forming a seal with the top of thetube 34. In these implementations, theremovable container 34 can contain absorptive materials and/or reagents for addition to thesample tube 36. - In implementations such as that of
FIG. 2D , therotor 24 has acontainer 34 in theopening 26. Therotor 24 also has alid 44 that automatically closes when the rotor starts to rotate, moving thetube opening 26 to a second location (shown on the right side at 46) so as to seal the tube area, as would be understood by the skilled artisan. In certain embodiments, the seal is hermetic or fluidic. Still in other embodiments, the described sealing can trigger a mechanical latch to hold the lid in a sealed position. - Turning to the implementation of
FIG. 3A , atube 36 having first 36A and second 36B elongate segments is shown. In this implementation, thesegments second segment 36B serves as a “cap” to thefirst segment 36A, as shown by reference arrow A, and such that various components may be disposed within and fluids may flow therethrough. - In exemplary embodiments, the
tube 36 comprises agel 48 and achemical reagent 50. In various implementations, thegel 48 can have thixotropic properties and become more liquid under shear, thus allowing the passage of certain bodily fluid components when the centrifugation occurs. - It is understood that in various implementations the
chemical reagent 50 can be any of several reagents such as protease or nuclease inhibitors for preventing the degradation of proteins of RNA/DNA. Thechemical reagent 50 may also contain various other known inhibitors, pHs, and/or salt concentrations that will prolong the preservation of thesample 32 as is known to an ordinary artisan. It is further understood that in use, thevarious components sample 32 can be disposed within thetube 36 so as to interact in a prescribed manner during centrifugation of thetube 36. - As shown in
FIG. 3B ,FIG. 3C andFIG. 3D , therotor 24 has been fitted with atube 36 that has asample 32, agel 48, and achemical reagent 50 that is to be selectively applied to thesample 32. The first action of the centrifuge, shown inFIG. 3C , can be to use a first speed (reference arrow B) such as a slower speed, to separate thesample 32 intoconstituent parts 54. In various implementations, thesample 32 can be separated by or into thegel 48. - Following separation, as shown in
FIG. 3D at reference arrow D, in some embodiments thecentrifuge system 10 can also incorporate a shaking or vibration to mix thesample 32. In some embodiments, thechemical reagent 50 can be added before separation of components. In some embodiments, thegel 48 is not necessary in the tube. It is understood that many implementations are possible. - In the implementations of
FIG. 4A andFIG. 4B , thecentrifuge system 10 keeps the contents at a stables temperature. In these implementations, a phase-changingmaterial 56, such as paraffin, that is constructed and arranged to keep thesample 32 at room temperature or buffer temperature spikes. - In another embodiment shown in
FIG. 4B , asmall cooling element 58 is disposed below or otherwise proximal to thecentrifuge 16 so as to actively cool thesample 32 for room temperature or refrigerated shipping. - In addition to the aforementioned temperature control techniques, in various implementations of the centrifuge system 10 a temperature logging module is integrated into the electronics of the device, thereby allowing for the tracking of temperatures throughout the operation and shipping process described herein. Samples that have been subjected to out-of-specification conditions, either due to harsh conditions or a failure of the temperature control methods can thus be rejected.
- In various implementations, the temperature history of a sample can be read wirelessly upon reception of the device and a decision to accept or reject the sample can be made based on that knowledge and the type of sample that was requested by the clinician.
-
FIG. 5A ,FIG. 5B andFIG. 5C depict another embodiment of thecentrifuge system 10. In these implementations, thecentrifuge system 10 can be housed in a package that contains sub-units 60, 62. In use, by removing theouter sleeve 64 reveals the sub-units 60, 62 as well as a high-level instruction sheet 66. In one implementation, thefirst sub-unit 60 contains the sample collection unit as well as the materials required for sample collection. - The
second sub-unit 62 contains a sample preparation and shipping unit. Once the sample is collected, it is placed in a receptacle in thesecond sub-unit 62. In these implementations, the sample preparation is actuated upon closing which can include centrifugation, time and temperature logging, refrigeration, tamper proofing, and recording to account for chain of custody. - In order to make the whole process achievable at home, the centrifuge is only one element of a larger kit. The centrifuge must be placed in a simple to understand workflow that the user can go through.
- Although the disclosure has been described with reference to preferred embodiments, persons skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the disclosed apparatus, systems and methods.
