Abstract
A system for separating plasma from whole blood comprises a blood separation device and a blood separation driver. The blood separation device includes a flexible tube having a needle and shield at one end and a filter member at the other end. The needle may be used to access blood in a conventional blood collection device. The separation driver applies a peristaltic force to the flexible tube of the blood separation device, thus drawing blood from the collection device through the tube and to the filter member. The driver also includes a frame having a collar and clamp mechanism for supporting the inlet end of the flexible tube, thus allowing use of the blood driver without directly exposing it to the blood. Plasma may be collected from the filter element. The present invention also provides blood dispensing systems and methods for dispensing whole and pre-filtered blood. Such blood dispensing systems comprise a blood dispensing device and a blood dispensing driver.
