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. Plasma may be collected from the filter element.
