1. A fluid delivery apparatus comprising(a) a fluid delivery assembly comprising:
- (i) a housing having a first chamber;
(ii) a support assembly disposed within said housing and including;
a. an elongated body having first and second communicating fluid passageways;
b. a fluid inlet means for permitting fluid flow into said first fluid passageway formed in said elongated body portion; and
(iii) stored energy means comprising an elongated tubular shaped elastomeric member circumscribing said elongated body and sealably connected proximate its ends to said elongated body, said elastomeric member having a central portion overlaying said second fluid passageway, said central portion of said elastomeric member being distendable by fluid flowing through said first and second fluid passageways from a first position in proximity with said elongated body to a second reservoir defining position where internal stresses are formed in said elastomeric member tending to return it to a less distended configuration;
(b) reservoir fill means interconnected with said fluid delivery assembly for filling said reservoir of said fluid delivery assembly, said reservoir fill means comprising;
(i) a container assembly including a container having a fluid chamber and displacement means movable relative to said fluid chamber;
(ii) an adapter assembly comprising a hollow housing having a barrel portion receivable within said first chamber of said housing of said fluid delivery assembly for connecting said adapter assembly to said fluid delivery assembly, said hollow housing having an outlet in communication with said fluid inlet means of said support assembly and a first open end for telescopically receiving at least a part of said container of said container subassembly and a second end; and
(iii) pusher means for engagement with said displacement means of said container subassembly to move said displacement means relative to said fluid chamber of said container upon telescopic movement of said container to urge fluid from said outlet of said hollow housing.

Abstract
An elastomeric bladder stored energy type medicament delivery apparatus which can be filled with a medicinal fluid using a closed-end, vial-type fill container and after being filled, can efficiently deliver the medicinal fluid to the patient at a controlled rate. The closed-end, vial-type fill means can be readily connected to and disconnected from the novel fluid delivery component of the apparatus. The fluid delivery device can also be filled by means of a secondary reservoir fill means.
