摘要: 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.

摘要: An ambulatory infusion and/or KVO (keep vein open) system (12, 18) has a gas-pressurized bladder arrangement (12) including a gas barrier associated therewith. The system includes a flexible bag of solution (13) inserted in a sleeve portion (36) of the bladder arrangement (12). Internal gas pressure which is developed within the bladder arrangement by a selectively initiated chemical reaction exerts a continuing pressure against the solution bag (13) to cause the solution to flow therefrom. A tubing set (18) of the system includes a flow restrictor (24) which is sized for minimal flow rates for indwelling catheter patency maintenance.

摘要: A catheter adapter of the type wherein compression applied to the catheter provides a retention force thereon and wherein notches are provided on the adapter for wrapping the catheter around the adapter in a manner such that a force applied to the catheter does not constitute a catheter separating force.
