STORAGE STABLE FLUID INJECTION DEVICE AND ASSOCIATED PROCESS
First Claim
1. A storage stable fluid injection device comprising:
- a reaction chamber capable of retaining a predetermined quantity of a chemical reagent that generates pressure when the chemical reagent is at least one of reacted, ignited, exploded, and decomposed;
an initiator for initiating at least one of reaction, ignition, explosion, and decomposition of the chemical regent;
a fluid retention chamber capable of retaining a fluid, wherein the fluid retention chamber includes an aperture; and
means for dispensing a fluid retained within the fluid retention chamber out of the aperture, and in turn, injecting the fluid.

Abstract
A storage stable needleless fluid injection device comprising a reaction chamber capable of retaining a predetermined quantity of a chemical reagent that generates pressure when the chemical reagent is at least one of reacted, ignited, exploded, and decomposed, an initiator for initiating reaction, ignition, explosion and/or decomposition of the chemical reagent, a fluid retention chamber capable of retaining a fluid, wherein the fluid retention chamber includes an aperture, and means for dispensing a fluid retained within the fluid retention chamber out of the aperture, and in turn, into a human or animal body, or other object. The device is capable of generating pressures in excess of 500 p.s.i. with the use of only very small amounts of the chemical reagent. Such high pressures enable needless injections to deep sub-dermal locations within a body or other desired environments.

15. A process for injecting a fluid comprising the steps of:
-
initiating at least one of reaction, ignition, explosion, and decomposition of a predetermined quantity of a chemical reagent retained within a reaction chamber;
generating pressure from at least one of the reacted, ignited, exploded and decomposed chemical reagent;
displacing a member associated with a fluid retention chamber with the generated pressure, to in turn, dispense a predetermined amount of fluid out of an aperture of the fluid retention chamber; and
injecting the fluid. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
