1. A dispensing device for dispensing medicaments to a patient comprising:
- (a) a supporting structure comprising a base assembly and an outer housing interconnected with said base assembly;
(b) a carriage assembly interconnected with said supporting structure for movement between a first position and a second position, said carriage assembly comprising a carriage having a carriage base provided with a plurality of circumferentially spaced openings and a generally cylindrically shaped sidewall terminating in a radially outwardly extending flange;
(c) locking means carried by said supporting structure for locking said carriage assembly in said first position;
(d) a reservoir defining assembly formed in accordance with an aseptic blow-fill-seal manufacturing technique and including a pre-filled, collapsible reservoir carried by said carriage assembly, said collapsible reservoir containing medicaments to be dispensed to the patient and having an outlet port, said reservoir defining assembly comprising a collapsible container having an integrally formed top, bottom and collapsible side wall, said top wall having an integrally formed neck portion sealably closed by a closure wall;
(e) guide means connected to said supporting structure for guiding travel of said carriage assembly between said first position and said second position, said guide means comprising a plurality of circumferentially spaced guide members connected to said base assembly and a guide rib connected to said housing of said supporting structure, said spaced-apart guide members being slidably received within said openings provided in said carriage base;
(f) a stored energy means operably associated with said carriage assembly for moving said carriage assembly between said first and second positions, said stored energy means comprising a coil spring having a first end in engagement with said supporting structure and a second end in engagement with said radially outwardly extending flange of said carriage;
(g) an administration set, including an administration line interconnected with said outlet port of said collapsible reservoir;
(h) fluid flow control means carried by said base assembly of said supporting structure for controlling fluid flow from said collapsible reservoir toward said administration set, said flow control means comprising;
(i) rate control means carried by said supporting structure for controlling the rate of fluid flow from said collapsible reservoir toward said administration set, said rate control means comprising a rate control plate having a plurality of fluid flow channels interconnected with said outlet of said collapsible reservoir; and
(ii) operating means carried by said supporting structure for controlling fluid flow between said collapsible reservoir and said rate control means; and
(j) adding means carried by said supporting structure for adding a medicament to said fluid contained within said fluid reservoir.
