1. A fluid delivery apparatus having a fluid delivery passageway, said apparatus comprising:
- (a) an elongated housing having walls defining an internal chamber;
(b) a support assembly connected to said housing and including an elongated body disposed within said internal chamber, said body having a receiving chamber, an inlet passageway and an outlet passageway in communication with said fluid delivery passageway;
(c) an elongated tubular shaped elastomeric member connected proximate its ends to said elongated body, said elastomeric member having a central portion disposed within said internal chamber of said housing and overlaying said inlet and outlet passageways, said central portion of said elastomeric member being distendable by fluid flowing through said first fluid passageway from a first position in proximity with said support to a second position to form a fluid reservoir;
(d) fill means interconnected with said housing for filling said reservoir, said fill means comprising;
(i) a container subassembly receivable within said internal chamber of said elongated housing, said container subassembly including;
a. a container having a fluid chamber having first and second ends;
b. displacement means movable relative to said fluid chamber for dispensing fluid from said chamber; and
c. closure means for closing said second end of said fluid chamber of said container, said closure means including connector means for interconnecting said fluid chamber of said container with a source of fluid.
