An apparatus for precisely mixing parenteral fluids with infusing agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane (209), or a membrane assemblage, which, in cooperation with a thin planar base (202), defines a fluid chamber (211) having a fluid outlet (214). In certain embodiments of the invention, a thin fluid permeable membrane (215) or membrane assemblage is disposed within the fluid chamber (211) to precisely control the rate of fluid flow through the fluid outlet (214). |
