Tube roller pumps for a medical device for extracorporeal blood treatment are disclosed. The pumps include a pump housing having a bent bearing surface and a rotor being rotatable inside the bearing surface, wherein a tubing segment can be introduced between the bearing surface and the rotor in the form of a loop. At the pump housing a stationary first receiving portion for accommodating one end of the loop-shaped tubing segment and a rocker arm including a second receiving portion for accommodating the other end of the loop-shaped tubing segment are provided, wherein the rocker arm is rotatable about a pivoting axis so that the second receiving portion with the tubing segment can be brought into at least two different positions and that a first position represents a threading position and a second position represents an unthreading position for the tubing segment. Medical devices for extracorporeal blood treatment including such tube roller pumps are also disclosed. |
