Abstract: A continuous flow centrifuge bowl includes a rotatable outer body, and a top and bottom core that are rotatable with the outer body. The bottom core has a wall extending proximally from a bottom wall. The proximally extending wall is radially outward from at least a portion of the top core and, together with the top core, defines a primary separation region in which initial separation of the whole blood occurs. The bowl may also have a secondary separation region located between the top core and the outer body, and a rotary seal that couples an inlet port and two outlet ports to the outer body. The inlet port may be connected to an inlet tube that extends distally into a whole blood introduction region. Additionally, one of the outlet ports may be connected to an extraction tube that extends into a region below the bottom core.

Abstract: A method for collecting plasma includes determining the weight and hematocrit of a donor, and inserting a venous-access device into the donor. The method then withdraws blood from the donor through a draw line connected to a blood component separation device, and introduces anticoagulant into the withdrawn blood. The blood component separation device separates the blood into a plasma component and a second blood component, and the plasma component is collected from the blood component separation device and into a plasma collection container. The method may then calculate (1) a percentage of anticoagulant in the collected plasma component, and (2) a volume of pure plasma collected within the plasma collection container. The volume of pure plasma may be based, at least in part, on the calculated percentage of anticoagulant. The method may continue until a target volume of pure plasma is collected within the plasma collection container.

Abstract: A method for collecting plasma includes determining the weight, height, and hematocrit of a donor, and calculating a donor plasma volume and a target plasma collection volume. The target plasma collection volume is based on the donor plasma volume and a target percentage of plasma. The method then withdraws blood from the donor through a line connected to a blood component separation device, and introduces anticoagulant into the withdrawn blood. The blood component separation device separates the blood into a plasma component and a second blood component, and the plasma component is collected from the blood component separation device and into a plasma collection container. The method may then calculate the volume of pure plasma collected within the plasma collection container, and continue processing/collecting until the calculated volume of pure plasma equals the target plasma collection volume.

Abstract: A method for the re-anticoagulation of platelet rich plasma in a blood apheresis system includes priming the blood apheresis system with anticoagulant, such that a volume of anticoagulant is transferred to a PRP container. The method may then transfer the anticoagulant within the PRP container to a red blood cell container, and collect a volume of platelet rich plasma within the PRP container. The platelet rich plasma may be collected in a plurality of cycles. Between collection cycles, the method may transfer a portion of the volume of anticoagulant from the red blood cell container to the PRP container.
