Abstract
A device for separating blood into a plurality of blood components by centrifugal force includes a first chamber for receiving a blood bag filled with blood to be separated. Each separated blood component is located in a separate portion of the blood bag according to its specific weight. A second chamber receives at least one component bag to be filled with a blood component. The component bag has an inlet opening connected to an outlet opening of the blood bag by a line that has a controllable valve. A displacement body in the first chamber exerts a pressing force onto the blood bag. A control unit opens the valve until a blood component passes into the component bag as a result of the pressing force. The displacement body generates the pressing force with the aid of the centrifugal force and/or with the aid of a spring force.
