ABSTRACT:
A single handed breast pump comprises a pump body (1) housing a piston (7) releasably connected to a hand lever (9) itself releasably pivoted to the pump body, the latter including a funnel (2) to be laid against the nipple and an outlet (4) at which a container may be connected. The funnel connects with a variable volume chamber in the pump body, said chamber having valves (11, 24) respectively for venting and for opening communication with the container outlet, whereby on operation of the hand lever an alternating pressure can be built up and relieved at the funnel.
