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