ABSTRACT:
An apparatus for the precise, ambulatory infusion of pharmaceutical fluids to a patient at controlled rates over extended periods of time of a character in which an elastic membrane cooperates with a thin, yieldably-deformable base to form a fluid chamber. When the base is deformed from a first configuration to a second configuration, internal stesses are formed within the membrane which causes it to tend to return toward its starting configuration and, in so doing, force fluid contained within the fluid chamber outwardly of the device through a fluid port.
