Abstract
A dispensing device for dispensing medicaments to a patient comprising a plurality of threadably interconnectable sub-assemblies. One of these sub-assemblies houses a novel collapsible fluid reservoir defining component that is carried by a carriage while another comprises a fluid delivery and control assembly that includes a novel flow control means that functions to control the flow of medicinal fluid from the fluid reservoir of the collapsible reservoir defining component toward the patient via a plurality of fluid flow control passageways. In one form of the invention the collapsible fluid reservoir is filled at time of manufacture. In another form of the invention the collapsible fluid reservoir can be filled in the field using a syringe assembly.
