摘要

A hand-pump unit (1) has a suction unit and a lifting chamber (9) surrounded by a wall (9'), connected to a breast attachment piece (3) and extending along a longitudinal axis. An operating device, especially a manual device, moves the suction unit to and fro. A membrane (10) moves against the wall inside the lifting chamber and has a section crosswise to the lifting chamber.
