Abstract

A pump module includes a peristaltic pump having a pump rotor, a drive mechanism to rotate the rotor, and a tubing clamp adjacent to and separate from the peristaltic pump. A cover is movable between a closed position on the pump module, enclosing both the pump rotor and the tubing clamp, and an opened position spaced from the pump module, exposing both the pump rotor and the tubing clamp. The cover carries a tubing organizer, which holds tubing. The tubing organizer serves, as the cover moves toward the closed position, to orient the tubing in a desired way with the pump rotor and tubing clamp. The tubing organizer also serves, as the cover moves toward the opened position, to orient the tubing away from the pump module.

Claims

1. A peristaltic pumping apparatus comprising a peristaltic pump rotor, a drive mechanism to drive the pump rotor, a tubing clamp operable to clamp close tubing received therein, a cover to enclose both the pump rotor and the tubing clamp, and a tubing organizer carrying first, second, and third tubing lengths, the tubing organizer also enclosed by the cover and serving to orient the tubing lengths so that the first tubing length is in registry with the pump rotor, the second tubing length is in registry with the clamp, and the third tubing length is out of registry with the pump rotor and the tubing clamp.

2. A peristaltic pumping apparatus according to claim 1 wherein the cover is movable to an open position away from the pump rotor and tubing clamp, and wherein the tubing organizer and tubing lengths are removable from the pump rotor and tubing clamp as a unit when the cover is in the open position.

3. A peristaltic pumping apparatus according to claim 2, further including a liquid receiving container attached to one of the tubing lengths.

4. A blood processing system comprising a blood separation device and a peristaltic pumping apparatus according to claim 1 or 2 or 3.
