Abstract

A biological fluid collection device that is adapted to receive a blood sample having a cellular portion and a plasma portion is disclosed. After collecting the blood sample, the biological fluid collection device is able to transfer the blood sample to a point-of-care testing device or a biological fluid separation and testing device. After transferring the blood sample, the biological fluid separation and testing device is able to separate the plasma portion from the cellular portion and analyze the blood sample and obtain test results.

Claims

1. A biological fluid separation device, comprising:

a rotatable body having a center of rotation and an outer periphery, the rotatable body having a body inlet adapted to receive a multi-component blood sample;

a separation chamber defined within the rotatable body and in fluid communication with the body inlet and having a chamber outlet spaced apart from the body inlet, the separation chamber adapted to receive both the multi-component blood sample; and

a blood component chamber defined within the rotatable body and in fluid communication with the chamber outlet, wherein when the separation chamber contains the multi-component blood sample and a rotational force is applied to the rotatable body, a blood component of the multi-component blood sample passes from the separation chamber into the blood component chamber and a second component of the multi-component blood sample is retained within the separation chamber,

wherein the blood component chamber is disposed adjacent the center of rotation and the separation chamber is disposed adjacent the outer periphery of the rotatable body.

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

3. The biological fluid separation device of claim 1, further comprising a diagnostic chamber in fluid communication with the blood component chamber.

4. The biological fluid separation device of claim 1, wherein the rotatable body is disc-shaped.

5. The biological fluid separation device of claim 1, wherein the blood component chamber receives the blood component of the multi-component blood sample upon the rotatable body being rotated by a processing instrument.

6. The biological fluid separation device of claim 1, further comprising a diagnostic chamber in fluid communication with the blood component chamber and including a detection zone readable by a processing instrument.
