Biological fluid separation device and biological fluid separation and testing system
First Claim
1. A biological fluid separation cartridge, comprising:
- a housing having a single inlet port and a flow channel defined within the housing in fluid communication with the single inlet port, the flow channel having a spiral shape;
a first collection chamber defined within the housing in fluid communication with the flow channel and including a first outlet port having a valve;
a second collection chamber defined within the housing in fluid communication with the flow channel and including a second outlet port, the second collection chamber isolated from the first collection chamber, and the second outlet port spaced apart from the first outlet port; and
an inlet channel in fluid communication with the single inlet port and the flow channel, wherein at least one of the inlet channel and the flow channel contains a sample stabilizer therein,wherein the valve comprises a deformable wall member and a septum, and wherein the septum covers the first outlet port.

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