Abstract (en)
[origin: US2007148010A1] 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 ( 33 a, 33 b, 33 c) 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 ( 2 a, 2 b). Flexible tube sections ( 43 ) are received in the tube bed and can be squeezed by the delivery rolls ( 33 a, 33 b, 33 c) to peristaltically deliver a medium. The two legs ( 2 a, 2 b) 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.
