Abstract
A fluid delivery device having a self-contained stored energy membrane for expelling fluids at a precisely controlled rate, which is of a compact, laminate construction. The device is of very low profile so that it can conveniently be used for the precise delivery of a small volume of pharmaceutical fluids, such as insulin, morphine and the like, into an ambulatory patient at precisely controlled rates over extended periods of time. The device includes strategically configured, multiple fluid chambers to achieve the maximum possible average percent of extension of the membrane and thereby assure adequate fluid delivery pressure.
