PROBLEM TO BE SOLVED: To provide a device for extracorporeal blood treatment which can be produced at optimum conditions in terms of assembly and costs and is resistant to wear.SOLUTION: The device includes a peristaltic pump for conveying fluid from a low-pressure side to a high-pressure side, the peristaltic pump comprising a rotor which is rotatable around a rotor axis, and a support area 21 which is formed around the rotor axis in an arcuate manner. Further the device includes an elastically deformable fluid line being able to be positioned between the rotor and the support area and being deformed between the rotor and the support area with rotation of the rotor, while forming a cross-sectional constriction, so that upon rotation of the rotor with respect to the support area, a fluid in the fluid line is conveyed from the low-pressure side to the high-pressure side. The device includes a machine housing part 100 realized as a formed sheet metal part 101, where the support area is formed in the machine housing part by plastic deformation.SELECTED DRAWING: Figure 3 |
