Abstract
A rotation unit includes a drive shaft and rotor of a peristaltic pump. The drive shaft attaches a rotor of the blood pump, extends along a central axis, and has a head delimited by a groove. A sliding section is arranged on the head. The rotation unit includes the drive shaft and the rotor with tube rollers which is attachable to the drive shaft. The groove has a flank arranged perpendicularly to the central axis. A locking element is movable transversely to the central axis. An abutment section is biased in the direction of the central axis and in the direction of the groove bottom by a spring arranged in the rotor. The abutment section is movable away from the central axis and groove bottom by an actuating section mounted on or formed integrally with the locking element. An abutment surface is arranged perpendicularly to the central axis.
