AMBULATORY ENERGIZED CONTAINER SYSTEM

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.
