Abstract

A blood separation device that is adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the blood separation device is able to separate a plasma portion from a cellular portion. After separation, the blood separation device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The blood separation device also provides a closed sampling and transfer system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer. The blood separation device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the blood separation device to the blood testing device. The blood testing device is adapted to receive the plasma portion to analyze the blood sample and obtain test results.

First claim

What is claimed is:

1. A biological fluid separation device adapted to receive a multi-component blood sample, the biological fluid separation device comprising:
a housing having an inlet port, a flow channel, and an outlet port having a valve, the inlet port and the outlet port in fluid communication via the flow channel, wherein the valve comprises a deformable wall member defining an interior space and transitionable between an extended position and a compressed position and a barrier disposed within the interior space of the deformable wall member, the barrier is reversibly transitionable between a closed position and an open position, and the barrier is transitioned from the closed position to the open position as the deformable wall member is transitioned from the extended position to the compressed position;
a separation member disposed within the flow channel between the inlet port and the outlet port;
a first reservoir defined within the flow channel between the inlet port and the separation member; and
a second reservoir defined within the flow channel between the separation member and the outlet port, wherein the separation member is adapted to trap a first portion of the multi-component blood sample within the first reservoir and to allow a second portion of the multi-component blood sample to pass through the separation member and into the second reservoir.

2. The biological fluid separation device of claim 1 , wherein the first portion of the multi-component blood sample is a cellular portion, and the second portion of the multi-component blood sample is a plasma portion.

3. The biological fluid separation device of claim 1 , wherein the inlet port is adapted to receive the blood sample via connection to a blood collection device.

4. The biological fluid separation device of claim 1 , wherein the separation member comprises a tangential flow filter.

5. The biological fluid separation device of claim 4 , wherein the tangential flow filter utilizes a cross-flow filtration to separate the first portion from the second portion.

6. The biological fluid separation device of claim 4 , further comprising an acoustic focus element disposed within the housing.

7. The biological fluid separation device of claim 1 , wherein the outlet port is adapted for connection to a point-of-care testing device for closed transfer of at least a portion of the second portion from the second reservoir to the point-of-care testing device via the outlet port.

8. The biological fluid separation device of claim 1 , further comprising a one-way valve disposed within the flow channel.

9. The biological fluid separation device of claim 8 , further comprising a pump in fluid communication with the flow channel for advancing the multi-component blood sample received within the flow channel through the one-way valve.

10. A biological fluid separation system for separating a multi-component blood sample, the biological fluid separation and testing system comprising:
a biological fluid separation device adapted to receive the blood sample, the biological fluid separation device comprising:
a housing having an inlet port, a flow channel, and an outlet port having a valve, the inlet port and the outlet port in fluid communication via the flow channel, wherein the valve comprises a deformable wall member defining an interior space and transitionable between an extended position and a compressed position and a barrier disposed within the interior space of the deformable wall member, the barrier is reversibly transitionable between a closed position and an open position, and the barrier is transitioned from the closed position to the open position as the deformable wall member is transitioned from the extended position to the compressed position;
a separation member disposed within the flow channel between the inlet port and the outlet port;
a first reservoir defined within the flow channel between the inlet port and the separation member; and
a second reservoir defined within the flow channel between the separation member and the outlet port, wherein the separation member is adapted to trap a first portion of the multi-component blood sample within the first reservoir and allow a second portion of the multi-component blood sample to pass through the separation member and into the second reservoir; and
a blood testing device having a receiving port engageable with the outlet port of the blood separation device for closed transfer of at least a portion of the second portion from the second reservoir to the blood testing device via the outlet port.

11. The biological fluid separation system of claim 10 , wherein the first portion of the multi-component blood sample is a cellular portion, and the second portion of the multi-component blood sample is a plasma portion.

12. The biological fluid separation system of claim 10 , wherein the blood testing device comprises a point-of-care testing device.

13. The biological fluid separation system of claim 10 , wherein the separation member comprises a tangential flow filter.

14. The biological fluid separation system of claim 13 , wherein the tangential flow filter utilizes a cross-flow filtration to separate the second portion from the first portion.

15. The biological fluid separation system of claim 10 , further comprising an acoustic focus element disposed within the housing.

16. The biological fluid separation system of claim 10 , wherein the inlet port is adapted to receive the blood sample via connection to a biological fluid collection device.

17. The biological fluid separation system of claim 10 , further comprising a one-way valve disposed within the flow channel.

18. The biological fluid separation system of claim 17 , further comprising a pump in fluid communication with the flow channel for advancing the blood sample received within the flow channel through the one-way valve.
