Abstract

A blood separation and testing system for a blood sample is disclosed. The blood separation and testing system includes a blood sampling transfer device adapted to receive a blood sample, a blood separation device, and a blood testing device. The blood separation device is adapted to receive a portion of the blood sampling transfer device such that with the blood sampling transfer device received within the blood separation device and a rotational force applied to the blood sampling transfer device, a plasma portion of the blood sample is separated from a cellular portion of the blood sample. The blood testing device is adapted to receive a portion of the blood sampling transfer device to analyze the plasma portion of the blood sample and obtain test results.

First claim

What is claimed is:

1. A biological fluid separation and testing system for a multi-component blood sample, the biological fluid separation and testing system comprising:
a biological fluid sampling transfer device adapted to receive the blood sample, the biological fluid sampling transfer device comprising:
a housing having a resiliently deformable upper portion, a lower portion removably connectable to the upper portion, the lower portion having an inlet port, an outlet port, and a flow channel, the inlet port and the outlet port in fluid communication via the flow channel, the flow channel adapted to receive the blood sample via the inlet port, the upper portion transitionable between an undeformed position and a deformed position; and
a puncturing element, a portion of which is disposed within the housing and adapted for movement between a pre-actuated position wherein the puncturing element is retained within the housing and a puncturing position wherein the puncturing element extends through the inlet port of the lower portion of the housing,
wherein actuation of the upper portion from the undeformed position to the deformed position moves the puncturing element from the pre-actuated position to the puncturing position, and
wherein after the puncturing element moves to the puncturing position, the upper portion returns to the undeformed position and the puncturing element returns to the pre-actuated position; and

a blood testing device having a receiving port adapted to receive the outlet port of the lower portion of the housing of the biological fluid sampling transfer device for closed transfer of a portion of the blood sample from the biological fluid sampling transfer device to the blood testing device via the outlet port.

2. The biological fluid separation and testing system of claim 1 , wherein the blood testing device comprises a point-of-care testing device.

3. The biological fluid separation and testing system of claim 1 , wherein with the biological fluid sampling transfer device received within the receiving port of the blood testing device, actuation of the upper portion from the undeformed position to the deformed position transfers the blood sample from the biological fluid sampling transfer device to the blood testing device via the outlet port.

4. The biological fluid separation and testing system of claim 1 , wherein with the blood sample received within the flow channel, the lower portion is removable from the upper portion.

5. The biological fluid separation and testing system of claim 4 , further comprising a blood separation device, wherein with the lower portion removed from the upper portion, the lower portion is receivable within the blood separation device.

6. The biological fluid separation and testing system of claim 5 , wherein with the lower portion received within the blood separation device, the blood sample contained within the lower portion is separated.

7. The biological fluid separation and testing system of claim 1 , wherein a portion of the housing includes a sample stabilizer.
