초록 ▼

A centrifugal blood processing system is disclosed having a rotor drive assembly that is rotatably mounted to a stationary base for rotation along a predetermined axis. A rotor assembly, which includes a blood processing chamber, is rotatably mounted with respect to the base for rotation about the axis. A flexible umbilical cable segment is provided for establishing fluid communication with the blood processing chamber. One end of the cable segment is fixed with respect to the base along the axis at one side of the rotor assembly while the other end of the cable segment is attached on the axis in rotationally locked engagement to the rotor assembly. Guide means are provided for causing the umbilical cable to rotate about the axis with the motor drive assembly. Means are provided for rotating the rotor assembly and the rotor drive assembly in the same direction with a speed ratio of 2:1 to prevent the umbilical cable from becoming completely twisted during rotation of the rotor.
