Abstract

A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as antibiotics, blood clotting agents, analgesics, and like medicinal agents from collapsible containers at a uniform rate. The dispenser includes a novel stored energy source that is provided in the form of a compressible-expandable member that functions to continuously and uniformly expel fluid from the device reservoir. The apparatus further includes a novel fluid flow control assembly that precisely controls the flow of the medicament solutions from the device reservoir to the patient.
