A tube pump is disclosed for conveying liquid or viscous media, with a pump head on which at least two pump rollers are arranged, which rollers can be brought into engagement in succession with a tube wherein the medium to be conveyed is contained, in such a way that the medium is transported by squeezing the tube tightly. The tube pump according to this invention is distinguished in that the pump rollers can be shifted between two end positions, one of which positions (pumping position) permits the pumping operation and the other position (park position) permits a tube change without manual twisting of the pump head and without displacement of the tube bed.

Tube pump with retractable rollers

A novel pump apparatus and method, the pump including a magnetically suspended and rotated impellor inside the pump housing. A novel sensor system detects the position of the impellor and thus provides the necessary information for operation of a suspension circuit for magnetically suspending the impellor. A valve member may be included as part of the impellor to prevent reverse flow in the event of impellor failure when used as a ventricular assist device.
