摘要： A pump driver, a disposable pump cartridge for use with the pump driver and a beverage dispenser employing the pump drive are disclosed. The disposable pump cartridge comprises at least one barrel 20 having an inlet valve 24 and an outlet valve 26 associated therewith. A piston 28 movable within the barrel 20 is retained in a minimum volume position during transit by a protrusion 22 on the internal surface of the barrel 20. The piston 20 has a piston shaft 28 with a hollow end arranged, in use, to releasably engage a piston driver to drive the piston 28 from its minimum volume position to an operative position, and to reciprocate the piston 28 within the barrel 20 in its operative position to draw fluid into and pump fluid from the barrel 20 via the inlet valve 24 and outlet valve 26 respectively. Methods of engaging, disengaging and changing the disposable pump cartridge are also disclosed.

摘要： An obstetric vacuum extractor (20) comprises a cylinder (22) communicating with a cup (26), and a handle (46) connected to a piston (38) via an extensible bias element (52) to evacuate the cup. The bias element permits relative movement between the handle and the piston. The bias element limits force transmitted to the piston, and movement of the piston relative to the handle operates an indicator to confirm that low pressure has been maintained within the cup. A cup for such an extractor comprises inner (130) and outer (132) sections, at least the outer section being reconfigurable, by applying distal force to a proximal side of the cup, from a convex insertion state for insertion into a mother's birth canal into a concave engagement state for engagement with a baby's head. A boundary between the sections is shaped such that the inner section may be concave while the outer section is convex, to create an inner suction cup.
