Abstract: A control housing assembly is disclosed. The housing assembly includes a housing and an escutcheon that manually connects to the housing by the engagement of escutcheon latches with housing catch channels. When the escutcheon is connected to the housing, the housing covers the escutcheon latches so as to obstruct the latches from being manually accessed to disengage the latches from the catch channels. The housing includes tool access slots through which a tool can be inserted to disengage a latch from a catch channel.

Abstract: A method and system of providing a needle-less injector specifically configured to the needs of a user. The method includes assembling a needle-less injector by positioning an inner housing within the outer housing such that the inner housing is axially movable within the outer housing between a ready position and a firing position. The method further includes receiving a user selection of a delivery spring weight from a plurality of available delivery spring weights. Then a delivery spring having the selected spring weight is placed within the inner housing. The completed needle-less injector having a delivery spring with the selected weigh may then be delivered to the user. In alternative injector configurations, the user may also select one or more of a skin tensioning spring weight or a hammer length along with or instead of the delivery spring weight.

Abstract: A method and system of manufacturing a needle-less injector to deliver an injection having a pre-determined injection dosage. The method and system include providing an injector housing, installing a compressible coiled delivery spring within the housing, and selecting a hammer having a length from a plurality of alternative hammers having different lengths, wherein the length of the selected hammer corresponds to the pre-determined injection dosage. The method further includes installing the selected hammer within the housing in contact with the compressible coiled delivery spring and further in contact with a syringe plunger such that upon assembly of the needle-less injector, decompression of the compressible coiled delivery spring causes the selected hammer to move laterally, thereby causing the syringe plunger to move laterally within a needle-less syringe to provide an injection having the pre-determined injection dosage corresponding to the length of the selected hammer.

Abstract: A needle-less injector device for delivering a dose of fluid intradermally, subcutaneously or intramuscularly to an animal or human. The device includes an inner housing having opposed ends. A syringe is disposed in one end of the inner housing. The syringe includes a nozzle for delivering a dose of fluid held within the syringe. A plunger is movably disposed within the syringe. A spring powered hammer is movably disposed within the inner housing. The hammer cooperates with the plunger to drive the dose of medicament from the nozzle. An injection delivery spring for powering the hammer is positioned and compressed between the other end of the inner housing and the spring powered hammer. An outer housing slideably supports the inner housing. A skin tensioning spring is mounted between the inner housing and the outer housing, the skin tensioning spring biasing the nozzle of the syringe against the animal or human.
