Peristaltic pump comprising modular casing
First Claim
1. A peristaltic pump of an apparatus for extracorporeal blood treatment for delivering fluid in the apparatus, the peristaltic pump comprising:
- a rotor driven to rotate about a rotor axis; and
a pump casing surrounding the rotor at least in part, the pump casing;
having a supporting surface which is configured to be curved around the rotor axis of the rotor,having a modular design and including at least a first supporting surface module configuring the supporting surface and at least a second casing module adapted to be coupled to the first supporting surface module and at least partly surrounding or receiving the rotor, the first supporting surface module comprising at least one standardized interface for coupling to at least one of the second casing module, a mounting module, or a casing element of the apparatus;
wherein an elastically deformable fluid line is adapted to be positioned between the rotor and the supporting surface and is deformed between the rotor and the supporting surface such that a cross-sectional constriction delivers fluid by rotation of the rotor.

Abstract
A peristaltic pump for an apparatus for extracorporeal blood treatment, especially for a dialysis machine, for delivering fluid in the apparatus is disclosed. The peristaltic pump includes a rotor driven to rotate about a rotor axis and a pump casing surrounding the rotor at least in part and including a supporting surface being configured to be curved around the rotor axis, wherein an elastically deformable fluid line is adapted to be positioned between the rotor and the supporting surface and is deformed between the rotor and the supporting surface while forming a cross-sectional constriction for fluid delivery by rotation of the rotor, the pump casing having a modular design and including a supporting surface module forming the supporting surface and a casing module adapted to be coupled to the former and surrounding the rotor at least in part.
