Fluid delivery apparatus with reservoir fill assembly
First Claim
1. A reservoir fill assembly for use in filling the fluid reservoir of a fluid dispenser for dispensing fluid to a patient, said reservoir fill assembly comprising:
- (a) a container subassembly including a container having a fluid chamber and a plunger movable relative to said fluid chamber from a first location to a second, spaced-apart location;
(b) an adapter subassembly comprising a hollow housing having a fluid outlet, an outer wall and an inner wall defining therebetween a generally annular shaped passageway for containing a fluid, said inner wall 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 connector means for connecting said adapter subassembly with the fluid dispenser; and
(c) an adapter sleeve mateable with said adapter subassembly including means for engagement with said plunger of said container subassembly to move said plunger between said first and second locations and further including a generally ring shaped member sealably received within said annular shaped passageway for urging fluid contained within said passageway outwardly thereof toward said fluid outlet of said hollow housing.

Abstract
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.

8. A reservoir fill assembly for use in filling the fluid reservoir of a fluid dispenser for dispensing fluid to a patient, said reservoir fill assembly comprising:
-
(a) a container subassembly including first and second containers each having a fluid chamber and a plunger movable relative to said fluid chamber from a first location to a second, spaced-apart location; (b) an adapter subassembly comprising a hollow housing having a fluid outlet, an outer wall and further including; (i) a first inner wall defining, in conjunction with said outer wall, a first generally annular-shaped passageway, said first inner wall having a first open end for telescopically receiving at least a portion of said first container of said container subassembly; and (ii) a second inner wall defining in conjunction with said outer wall a second generally annular shaped passageway, said second inner wall having a first open end for telescopically receiving at least a portion of said second container of said container subassembly; (c) an adapter sleeve mateable with said adapter subassembly including first means for engagement with said plunger of said first container of said container subassembly to move said plunger between said first and second locations and further including second means for engagement with said plunger of said second container of said container subassembly to move said plunger between said first and second locations. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
