ABSTRACT:
The disclosure is a disposable low-mass processing channel and multilumen tube system for operation with a 2.omega. sealless centrifuge in which the centrifuge rotor rotates at 2.omega. axially to a platform rotor rotating at 1.omega. and to a fixed axial clamp on the multilumen tube.
The blood processing channel is equipped with several tube lumens for access to different blood fractions to be separated by the centrifuge action. The plastic lumen tube is supported at each end by plastic reinforcing tubes clamped at clamp ends and ending in thrust drive bearings at the free ends. The thrust drive bearings are arranged for rotation about the multilumen tube and for fixation with respect to slotted conical reinforcing tube receivers on the 1.omega. rotor.
Centrifugal force fixes the thrust bearings in place within the slotted conical reinforcing tube receivers. The low-mass central portion of the multilumen tube is unsupported; in operation it flies free in a wide bend. The multilumen tube is easily placed in position in the slots of the reinforcing tube receivers of the centrifuge rotor, by side-entry, and are subsequently held in place by the beam strength of the flexed reinforcing tubes and by centrifugal force.
