1. A dispensing device for dispensing medicaments to a patient comprising:
- (a) a supporting structure;
(b) a pre-filled unitary container formed by an aseptic blow-fill-seal process, said unitary container being carried by said supporting structure and having a tapered collapsible sidewall;
(c) stored energy means carried by said supporting structure and operably associated with said pre-filled unitary container for collapsing said collapsible sidewall thereof; and
(d) flow control means carried by said supporting structure for controlling fluid flow from said unitary container toward the patient.

Abstract
A compact, easy-to-use dispensing device that includes a uniquely configured unitary fluid container formed by a blow-fill-seal process. The container has a collapsible, tapered sidewall of progressively varying wall thickness that, upon being acted upon by an elastic member, will deliver an injectable parenteral fluid contained within the fluid reservoir to the patient at a substantially constant flow rate.

23. A dispensing device for dispensing medicaments to a patient comprising:
-
(a) a supporting structure; (b) a hermetically sealed, unitary collapsible container carried by said supporting structure, said unitary collapsible container being formed using aseptic blow-fill-seal manufacturing techniques and having a pre-filled, sealed fluid reservoir having an outlet port; (c) a spring operably associated with said collapsible container for collapsing said collapsible container; (d) an administration set, including an administration line interconnected with said outlet port of said fluid reservoir; (e) fluid flow control means carried by said supporting structure for controlling fluid flow from said sealed fluid reservoir toward the patient, said fluid flow control means comprising; (i) rate control means for controlling the rate of fluid flow from said sealed fluid reservoir toward said administration set; and (ii) operating means for controlling fluid flow between said sealed fluid reservoir and said rate control means. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
