Abstract
Gas is generated at a controlled rate from a liquid and solid phase combination that generated gas upon contact, by using diffusive transport of the liquid toward the solid phase surface to prolong the rate of gas generation, with a variety of alternatives for controlling the rate of diffusive transport. This system is useful in infusion devices for delivering medications or other beneficial liquids from a retaining pouch at controlled rates over a prolonged period of time.
