Peristaltic Pump With Easy Tube Load Feature

This design of a roller-type peristaltic pump lends itself to easier and quicker loading of the pump tubing than that afforded by previous designs.

Figs. 1 and 2 illustrate the two steps involved in loading the pump tubing and Fig. 3 is a cross-sectional view of Fig. 2 in the direction indicated by arrows A-A.

The pump disk or cup 1 has tubing slots 3 therein in which the pump tubing 5 is laid. The body 7 of the pump rotor is cutaway along a chord in such manner that a clear path extends across the rotor body from one tubing slot 3 to the other, as can be seen in Figs. 1 and 2.

To load the pump, the rotor 7 is turned, by hand or power, until the cutaway portion of the rotor body is aligned with one set of slots 3, as shown in Fig. 1. The tubing 5 is inserted under the top plate 9 of the rotor 7 and down into the slots 3.

The rotor 7 is then turned through 180 degrees and the other side of the tubing loop is inserted in the other set of slots 3, as seen in Fig. 2.

Unloading of the tubing 5 is accomplished by the reverse of the loading operation.
