Abstract
Abstract The volumetric perfusion pump displaces a liquid (S) inside a flexible, deformable pipe (2) forming the pump body. This is done by fingers (3), side by side and driven by a rotating shaft parallel to the pump body. Around this is a cam (5) formed by eccentric discs pressing the fingers. The body length crushed during the first half revolution of the camshaft is greater than that during the second half. The first half length is, in fact, double that of the second half. The fingers are rectangular plates.
