Abstract: A hose fastening arrangement for roller pumps, especially for a heart-lung machine, which possesses a head constituted of a pump stator and pump rotor, including fastening devices for fastening of the pump piece which is inserted into the pump head of the roller pump. The hose fastening arrangement for roller pumps of the above-mentioned type is detachable from the pump head of the roller pump.

Abstract: A roller pump for heart-lung machines with a pump head, consisting of a pump stator which possesses a pump bed serving as a support for a hose piece or length, and a pump rotor which is arranged in the pump stator so as to be rotatable about its central longitudinal axis and which possesses rollers rotatably supported on a roller carrier, which during a rotation of the pump rotor travel along the hose piece which is inserted into the pump head, and including a drive unit for producing the rotational movement of the pump rotor and with a pump housing for the support of the pump head and for receiving the drive unit which is inventively configured in such a manner that the drive unit is connected with the pump head whereby the pump head is moveable relative to the pump housing.
