ABSTRACT:
An ambulatory infusion system includes a spring-pressurized reservoir to facilitate portable use of the system. The system includes a liquid-filled flexible container, and a pair of opposed platens between which the flexible container is removably positionable. Energy-storing, clip-like biasing springs act against the platens to urge them toward each other, thereby effecting pressurization of the liquid within the container. A tubing set of the system preferably includes a non-adjustable flow restrictor, which may be sized for relatively low flow rates to permit the system to be used for catheter patency maintenance.
