Peristaltic pump
First Claim
1. Peristaltic pump, with a rotor (3) received in a housing, which is provided with at least one rotatably supported conveyor roller (33a, 33b, 33c), as well as with a tubing holder (2) for receiving of at least one flexible tubing section (43) that is squeezable by the conveyor roller (33a, 33b, 33c) for peristaltically conveying a medium, characterized in that the tubing holder (2) is provided with a tubing bed body member (25) for receiving of at least one flexible tubing section (43), whereby the inlet and/or the outlet region (35,36) of the tubing bed body member (25) is designed such that the cross sectional area of the tubing relevant for the conveying is continuously decreased and increased, respectively, by the conveyor roller (33a, 33b, 33c) rolling over the particular tube section (43).

Abstract
The invention relates to a multi-channel peristaltic pump, wherein the housing is constituted by a dimensionally stable support frame (1) and a tube retainer (2) clipped thereto by means of a snap connection. A rotor (3) is provided with three rotatable delivery rolls (33a, 33b, 33c) and is mounted on the support frame (1). The tube retainer (2) is provided with a tube bed body (25) which defines on the inside a tube bed and at the end two legs (2a, 2b). Flexible tube sections (43) are received in the tube bed and can be squeezed by the delivery rolls (33a, 33b, 33c) to peristaltically deliver a medium. The two legs (2a, 2b) are resiliently elastic so that they can be radially clipped into the support frame (1). The tube bed body (25) has a substantially omega-shaped design and is provided with a continuous inlet and outlet area that ensures a peristaltic delivery of the respective medium with only few pulsations. The inventive pump is compact in design, consists of few components and can be quickly and easily assembled.
