Abstract

See full text

A peristaltic pump for an apparatus for extracorporeal blood treatment, especially for a dialysis machine, for conveying fluid in the apparatus is disclosed. The peristaltic pump includes a rotor driven by a drive shaft, the rotor interacting with an elastically deformable fluid line so as to form a cross-sectional constriction which is displaced along the fluid line for conveying fluid by rotation of the rotor, wherein the rotor is coupled to the drive shaft by a coupling structure so as to transmit a torque, wherein the coupling structure couples the rotor and the drive shaft with a play in the direction of rotation relative to each other.
