    Abstract: A rotor (2a-2e) for collecting and centrifuging biological fluids in a range of volumes. The rotor includes an elastic impermeable diaphragm (31) which defines at least a portion of a variable-volume processing chamber (30), where the fluid is centrifuged. The rotor includes a rigid mounting member (28), to which the diaphragm is mounted and which is held and spun by a chuck. Preferably, this rigid mounting member includes a boundary wall (10) which together with the elastic diaphragm defines the chamber. The boundary wall may be a substantially imperforate circular wall which extends to the periphery of the processing chamber but defining one opening, preferably near the axis of rotation, permitting a conduit (13) or conduits (83, 93, 163, 165, 188) to pass therethrough so as to be in fluid communication with the processing chamber. The rotor may include a separate structure (40, 190, 244) for controlling the flow of liquid out of the chamber into the conduit. In a preferred embodiment, this outlet-control structure is a perforate, substantially rigid wall or plate (40), located within the processing chamber and mounted adjacent the rigid boundary wall. In an alternative embodiment, the outlet-control structure for controlling flow from the processing chamber to the conduit may include at least one tube or preferably a set of tubes (190), wherein each tube provides fluid communication between the chamber and the conduit. In one preferred embodiment, grooves (244) in the boundary wall may be used as the outlet-control structure.

    Abstract: The system includes a needle (72) (or other cannula-like device) for insertion into a vein of the donor and drawing whole blood therethrough, a variable-volume rotor (2a) for holding the blood after it is drawn, and a motor (50) for spinning the rotor so as to cause the blood to seperate into components, for example, plasma and red blood cells. The system also provides for a container for collecting a separated component. In a preferred embodiment two containers are used: the first container (92) for containing an anticoagulant, which is preferably added to the whole blood as it is drawn from the donor, and then for storing the plasma after it has been separated from the red blood cells, and the second container (91) for storing the separated red blood cells. The system further includes tubing (73), which may have valving (81) built into it and which may be acted on externally, so as to direct the blood components in the desired manner. The tubing connects the needle (72), the rotor (2a), and the first and second containers (92, 91). With the valving, the tubing is able to permit (i) the flow of whole blood from the needle (72) to the rotor (2a), (ii) the flow of anticoagulant from the first container (92) to the whole blood flowing from the needle to the rotor, (iii) the flow of plasma from the rotor to the first container, and (iv) the flow of red blood cells from the rotor to the second container (91). The motor (50) and the valving are preferably controlled by an electronic controller. Preferably, the system also includes a pump (61), which is also controlled by the controller, and which forces the blood components out of the rotor (2a) to the tubing. The pump is preferably able to draw the whole blood into the rotor.
