DETAILED DESCRIPTION
[0056] The various embodiments disclosed or contemplated herein relate to preparing biological specimens, such as blood, for shipment or transport. In various implementations, the sample preparation system is embodied as a centrifuge, using a motor to create a defined centrifugal force on the sample contained within the rotor in order to separate specimen components using gravity. When used in conjunction with a tube containing particular gels or reagents known in the art, the centrifuge separates the individual components of the sample, as would be well appreciated in the art.
[0057] It is understood that the various embodiments or devices, methods, and systems disclosed herein can be incorporated into or used with any other known medical devices, systems, and methods.

[0058] Turning to the drawings in greater detail,
[0059] In these and other implementations, the rotor 24 has at least one opening 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 and centrifuge system 10 as easy-to-operate as possible enabling use of the system 10 in the home, basic clinic, field, and/or retail settings.
[0060] 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 of
[0061] In the implementations of
[0062] According to these implementations, after a sample 26 is processed and is ready to be transported and/or shipped for analysis, the tab 22 can be affixed to the device housing 12 with adhesive 14 to prevent the centrifuge 16 from being re-opened. In various implementations, the adhesive 14 is single usage tape. It is understood that in other embodiments, the lid 22 can be closed with other methods or mechanisms known in the art.
[0063] 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.
[0064] Continuing with the drawings,
[0065]
[0066] As shown in the implementation of
[0067] In certain implementations, the lid 20 may serve as the only covering, whereas in alternate implementations like that of
[0068] In the implementation of
[0069] In exemplary embodiments, the biological specimen can be in a container such as a HemoLink tube 36 from the user. In other embodiments, the rotor 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.
[0070] It is understood that these implementations of the cover opening 18A and rotor opening 26 are constructed and arranged so as to allow for the ease of use, that is, passage of the biological specimen into the rotor 24 for use. It will be appreciated that the cover 18 can be constructed from any number of materials, some non-limiting examples being plastic, Tyvek and cardboard.
[0071] 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.
[0072] 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.
[0073] Continuing with the implementation of
[0074] 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 locking switch 19 opening, the locking switch 19 is disabled. Subsequently, when the lid is returned to the closed position, the activation switch 21 is able to start the centrifuge 16, such as via a magnet disposed within the lid 20 that is constructed and arranged to activate the switch 21 and initiate centrifugation.
[0075] In the implementations, the switches 19, 21 are secured to the frame 16 and in operational communication with the rotor 24. That is, the rotor 24 is in operational communication with a motor 25 disposed within the housing 12, as well as with a printed circuit board (PCB) 28 via a PCB mount 29 and motor mount 31. In various implementations, the PCB 28 is constructed and arranged to operate and control of the timing and speed of the centrifuge rotor 24.
[0076] In various implementations, such as that of
[0077] Further, the PCB (or other microcontroller) 28 of these implementations is in operational communication with the switches 19, 21 and other electronic components such as memory, processors or other electronic devices known in the art. In exemplary implementations, they can be housed in a first cavity 37 defined within the frame.
[0078] Continuing with the switches 19, 21, in various implementations, the system 10 can be programmed such that the activation switch 21 initiates a timer on the PCB 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.
[0079] 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.
[0080] 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 the PCB 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.
[0081] In various implementations of the system 10, the electronic components such as the PCB 28 are constructed and arranged to allow the system 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.
[0082] 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 primary larger capacity battery 33 can be provided to power the rotor 24, and another smaller capacity battery disposed, for example, on the PCB 28 or elsewhere within the frame 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.
[0083] 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.
[0084] 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 the electronics housing 37 and in operational communication with the battery 33, PCB 28 and/or any other modules or processors and sensors necessary to perform the contemplated functions.
[0085] 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.
[0086] 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.
[0087] As also shown in
[0088] As shown in
[0089] In the implementation of
[0090] As shown in
[0091] In implementations such as that of
[0092] Turning to the implementation of
[0093] In exemplary embodiments, the tube 36 comprises a gel 48 and a chemical reagent 50. In various implementations, the gel 48 can have thixotropic properties and become more liquid under shear, thus allowing the passage of certain bodily fluid components when the centrifugation occurs.
[0094] 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. The chemical reagent 50 may also contain various other known inhibitors, pHs, and/or salt concentrations that will prolong the preservation of the sample 32 as is known to an ordinary artisan. It is further understood that in use, the various components 48, 50, and a sample 32 can be disposed within the tube 36 so as to interact in a prescribed manner during centrifugation of the tube 36.
[0095] As shown in
[0096] Following separation, as shown in
[0097] In the implementations of
[0098] In another embodiment shown in
[0099] 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.
[0100] 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.
[0101]
[0102] The second sub-unit 62 contains a sample preparation and shipping unit. Once the sample is collected, it is placed in a receptacle in the second 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.
[0103] 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.
[0104] 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.
