Abstract

The invention relates to a device and a method for separating whole blood into blood components. The device has a collecting container for collecting whole blood, a primary container, and one or a plurality of satellite containers downstream from the primary container. The collecting container is connected to the primary container via a branch line containing a leucocyte filter. In addition, a bypass line is provided between the collecting container and the primary container for creating a fluid connection that circumvents the leucocyte filter. The primary container is also connected, via an additive line, to an additive container containing an additive agent for storing a blood component. The method involves collecting the donor's whole blood in the collecting container and conveying it, via the bypass line, into the primary container. The whole blood located in the primary container is then separated by centrifuigation into an erythrocyte layer and a mixed layer of blood plasma and thrombocytes. The mixed layer of blood plasma and thrombocytes is then conveyed from the primary container into the first satellite container. Subsequently, the erythrocytes in the primary container are resuspended in the additive agent, then conveyed from the primary container through the leucocyte filter into the collecting chamber.
