An apparatus for delivering fluids at a precisely controlled rate which comprises a fluid dispensing component having a fluid reservoir for containing the fluids to be delivered and a reservoir fill component which can be removably interconnected with the fluid dispensing component. The dispensing component can be used for the precise infusion of pharmaceutical fluids to an ambulatory patient at controlled rates. The reservoir fill assembly is uniquely designed to accept a vial component of conventional construction which is partially received within a novel adapter subassembly that can readily be removably interconnected with the fluid dispensing component.

[ We claim:] [1.] A device for use in infusing medicinal fluid into a patient at a controlled rate comprising:(a) a fluid dispenser including:(i) a base having a lower surface provided with a dispenser connector;(ii) a stored energy means for forming, in conjunction with said base a fluid reservoir having an inlet in communication with said dispenser connector and an outlet, said stored energy means comprising at least one distendable member superimposed over said base, said member being distendable as a result of pressure imparted by the fluids to be infused to establish internal stresses, said stresses tending to move said member toward a less distended configuration;(iii) an outlet port in communication with said outlet of said fluid reservoir for dispensing fluids from the device; and(b) a reservoir fill assembly interconnectable with said base of said fluid dispenser for filling said fluid reservoir thereof, said reservoir fill assembly comprising:(i) a container subassembly including a container having a fluid chamber and displacement means movable relative to said fluid for dispensing fluid from said chamber;(ii) an adapter subassembly comprising a hollow housing having a first open end for telescopically receiving at least a part of said container of said container subassembly and a second end, said hollow housing further including an adapter connector mateably interconnectable with said dispenser connector for removably interconnecting said adapter subassembly with said base of said fluid dispenser; and(iii) an adapter sleeve slidably movable relative to said adapter subassembly and including means for engagement with said displacement means of said container subassembly to move said displacement means relative to said fluid chamber of said container.
