To enable geriatric or morbid users to be able to insert a delivery tube (11) into a pressure infusion apparatus (1) between the delivery or pumping mechanism (3, 23) and pressure or application means (2, 22, 32) a cam plate is arranged which bears with a portion of its outer periphery on the pressure means which presses against the action of a spring against the cam plate. Via rotation direction-dependent drivers (8) the cam plate is connected to the delivery mechanism (3, 23) in such a manner that for a given direction of rotation the delivery mechanism (3, 23) and the pressure means can be moved towards or away from each other.
