An injectable medicament dispenser for use in controllably dispensing fluid medicaments such as insulin, antibiotics, oncolytics and the like from a prefilled container at a uniform rate. The dispenser includes a unique stored energy source in the form of a compressively deformable, polymeric elastomeric member that provides the force necessary to controllably discharge the medicament from the prefilled container which is housed within the body of the device. After having been deformed, the polymeric, elastomeric member will return to its starting configuration in a highly predictable manner.

[ I claim:] [1.] A dispensing apparatus for dispensing fluids comprising:(a) a housing;(b) a fluid reservoir disposed within said housing, said reservoir having outlet means for permitting fluid flow from said fluid reservoir;(c) stored energy means for acting upon the fluid contained within said reservoir to cause the fluid to controllably flow through said outlet means, said stored energy means comprising a compressively deformable, elastomeric polymeric member carried by said housing, said compressively deformable, elastomeric polymeric member upon being compressively deformed expands substantially axially to cause fluid flow from said reservoir; and(d) operating means carried by said housing for controllably deforming said elastomeric polymeric member.
