SYSTEMS AND METHODS FOR COLLECTING BLOOD COMPONENTS.

摘要

Systems and methods for collecting cellular-rich concentrates of blood are disclosed. Blood from donor (78) is mixed with anticoagulant (90) and conveyed to a first separation device (12) for separating an anticoagulated cellular suspension from blood. The anticoagulated cellular suspension is conveyed to a second separation device (14) for removing leukocytes. Leukocyte-depleted cellular suspension is conveyed to a third separation device (16) for concentrating the leukocyte-depleted cellular suspension into a cellular-rich concentrate and a cellular-poor component and a portion of the cellular-poor component is returned to the donor (78). A controller (88) is used to control the process including monitoring the rate at which anticoagulant carried in the cellular-poor component is being infused with the returned cellular-poor component into the donor (78).
