Abstract
A blood processing device includes a pump system, a valve system, a continuous-flow centrifuge, and a controller programmed to control the operation of the pump system, the valve system, and the centrifuge to execute a blood separation procedure. The blood separation procedure executed by the controller includes pumping whole blood through a leukoreduction filter and into the centrifuge, separating the blood in the centrifuge into red blood cells and plasma, with an interface between the red blood cells and plasma located at an interface position within the centrifuge, and pumping at least a portion of the red blood cells and at least a portion of the plasma out of the centrifuge.
