Biological fluid sampling transfer device and biological fluid separation and testing system
First Claim
1. A 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 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, when the lower portion of the housing is removed from the upper portion of the housing, the inlet port and the flow channel in the lower portion are sealed and the puncturing element is contained within the upper portion of the housing.

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.

10. A biological fluid sampling transfer device adapted to receive a multi-component 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, 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 wherein, when the lower portion of the housing is removed from the upper portion of the housing, the inlet port and the flow channel in the lower portion are sealed and the puncturing element is contained within the upper portion of the housing. - View Dependent Claims (11, 12, 13)
