Abstract
Apparatus for the induced infusion of a liquid from a flexible liquid bag comprises a pumping bulb, elastic inflatable means coupled to the bulb for inflation thereby, and a flexible sleeve for retaining the liquid bag firmly against a first portion of the inflatable means for applying the pressure thereof to the bag to induce infusion of the liquid therefrom. The elastic inflatable means includes a second portion which serves as an accumulator for accumulating pressurized fluid pumped by the bulb and comprises an outer non-elastic sheath for limiting the accumulation of the pressurized fluid therein. In one described embodiment, the two mentioned portions of the elastic inflatable means are constituted of separate units, one being a bag-presser including an inflatable bladder against which the liquid bag is pressed by the flexible sleeve, and the other being a separate accumulator including an inflatable tube enclosed by the non-elastic sheath. In a second described embodiment, both of the mentioned portions of the elastic inflatable means are constituted of a single elastic bladder enclosed only at its mid-portion by the flexible sleeve, the end portions of the bladder projecting outwardly of the flexible sleeve and being enclosed by the non-elastic sheath so as to serve as the accumulators for accumulating the pressurized fluid.
