1. An apparatus for use in infusing medicinal fluid into a patient at a controlled rate comprising:

  • (a) a fluid dispenser including;

    (i) a base having a receiving chamber;

    (ii) a stored energy means for forming, in conjunction with said base a fluid reservoir having an inlet in communication with said chamber 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 assembly including a container having a fluid chamber and displacement means movable within said fluid chamber;

    (ii) an adapter assembly comprising a hollow housing having an outlet in communication with said inlet of said fluid reservoir and also having a barrel portion receivable within said receiving chamber of said base of said fluid dispenser to connect said adapter assembly to said base, said container being telescopically receivable in said housing; and

    (iii) pusher means for engagement with said displacement means of said container assembly to move said displacement means within said fluid chamber to urge fluid flow toward said outlet of said adapter assembly.
