Abstract (en)

[origin: WO9116933A1] A disposable infusion apparatus (10) includes proximal, distal and intermediate segments of IV tubing (14) connected via couplings (20, 26). The intermediate segment (34) has a length sufficient for operative engagement with a pumping member (32) of a peristaltic pump throughout a pumping stroke thereof. The intermediate segment (34) further has a maximum Durometer of seventy-five on the Shore A scale. The pumping member (32) includes a plurality of fingers (32a) mounted in side-by-side substantially parallel relationship for individual reciprocation. Motor driven cams (36) individually reciprocate respective ones of the fingers in a predetermined timed sequence so that when the linearly disposed intermediate segment (34) is squeezed by the fingers (32a), intravenous fluid in the tubing will be pumped therethrough. The disposable apparatus (10) further includes a door (40) connected to opposite ends of the intermediate segment (34) and which is releasably loadable in a case (12) to place the intermediate segment into operative engagement with the pumping member.
