Abstract
Tube roller pumps for blood treatment devices are disclosed. The pumps include a curved surface with a rotor rotatable therein. The rotor attaches via a shaft reception to a drive shaft of the pump. The rotor has a first locking element for axially locking the rotor on the shaft and a second locking element for rotationally coupling the shaft and the rotor. The shaft reception and the drive shaft guide the rotor to a position on the shaft, when pushed onto the shaft, and, at this position, the first element may be moved by the shaft from locked to released. The rotor, when pushed further onto the shaft, is moved to another position at which the first element is automatically moved back to locked and the second element may be brought into manual engagement with the shaft to transmit torque from the shaft to the rotor.
