Patent ID: 6890291

Claim:
A cassette adapted for mounting on a console, wherein the console includes a first motor and pump rotors driven by a second motor, comprising: a frame; a continuous flow centrifuge supported on the frame, said continuous flow centrifuge comprising: a housing, a rotor rotably supported in the housing, adapted to be driven by the first motor when the cassette is mounted on the console, and a disk mounted to the rotor, wherein the rotor is supported in a horizontal position relative to the console when the cassette is mounted on the console, said continuous flow centrifuge having an input port adapted to receive and hold a first length of flexible tubing for delivering fluid to the disk and an output port adapted to receive and hold a second length of flexible tubing for removing fluid from the disk; and a manifold supported on the frame, said manifold comprising: a first tube receptacle, a second tube receptacle, a third tube receptacle and a fourth tube receptacle, each of the tube receptacles adapted to receive and hold a length of flexible tubing, a first pump tube segment defining a first end and a second end; a second pump tube segment defining a first end and a second end, and a first fluid pathway, a second fluid pathway, a third fluid pathway and a fourth fluid pathway, wherein the pump tube segments, the lengths of flexible tubing and the fluid pathways are adapted to contain fluid, wherein the first tube receptacle is connected to the first end of the first pump tube segment by a first fluid pathway, the second end of the first pump tube segment is connected to the second tube receptacle by a second fluid pathway, the third tube receptacle is connected to the first end of the second pump tube segment by a third fluid pathway, and the second end of the second pump tube segment is connected to the fourth tube receptacle by a fourth fluid pathway, wherein the first length of flexible tubing connects the input port of the continuous flow centrifuge to the second tube receptacle, and the second length of flexible tubing connects the output port of the continuous flow centrifuge to the third tube receptacle, and each of the pump tube segments is adapted for interface with a separate pump rotor chosen from among the pump rotors driven by the second motor when the cassette is mounted on the console, whereby fluid in each of the pump tube segments may be forced from each of the pump tube segments to a selected one of the respective fluid pathways to which the pump tube segments are connected.
