Pumping mechanism, pump and method of operating a pump

Abstract

A pumping mechanism (1), in particular for a pump for administering medical fluid to patient, is provided, wherein the pumping mechanism is configured to act onto a fluid conduit (21) of a pump (2), the pumping mechanism comprising a pumping section (13) movable with respect to said fluid conduit such that a fluid flow through said fluid conduit is generated. The pumping mechanism comprises an eccentric ring (11) for reception of ac shaft of a motor of a pump and a multiplicity of connecting elements (12) each operatively coupled to the pumping section at at least one of a multiplicity of different locations of the pumping section and operatively coupled to the ring in such a way that an eccentric rotational movement of the ring is converted into a translational movement of each of the multiplicity of locations. Furthermore, a corresponding pump (2) and a mechanism of operating a pump is provided.
