Abstract
Pump actuator assembly for use in operating a pump for supplying intravenous liquid to a patient which comprises a housing having a sealed chamber therein with a portion thereof being covered by a flexible membrane. A plunger is mounted in the housing so that a portion thereof is disposed in the sealed chamber for movement between innermost and outermost positions. A constant quantity of liquid fills the sealed chamber. A booth encloses the portion of the plunger disposed in the fluid. A liquid-tight seal is provided between the booth and the housing to permit the plunger to be moved between the innermost and outermost positions so that the flexible membrane can be caused to move between extended and retracted positions.
