Abstract
Systems and methods are provided for separating blood into two or more components. A blood separation system includes a blood separation device and a fluid flow circuit configured to be mounted to the blood separation device. The blood separation device includes a centrifugal separator and a spinning membrane separator drive unit incorporated into a common case, which allows for fluid separation by two different methods. Depending on the separation procedure to be carried out, the fluid flow circuit paired with the blood separation device may include only one separation chamber configured to be mounted to the centrifugal separator or spinning membrane separator drive unit or two separation chambers, with one being mounted to the centrifugal separator and the other to the spinning membrane separator drive unit. The system may be used to separate and collect any combination of red blood cells, plasma, and platelets.
