Claim Text:
1. A needle-free injection device comprising: an injector body; an injector tube positioned within the injector body, said injector tube housing a main spring configured to be selectively compressed to place the needle-free injection device in an armed configuration and a hammer, which injector tube is configured to move laterally away from a syringe end of the injector body when pressure is applied to a nozzle end of a needle-free syringe prior to an injection; at least one handle attached with a pivot hinge to the injector body such that the handle pivots between an open and a closed position and such that the handle remains attached to the injector body during an injection; a linkage between the handle and the main spring causing the main spring to be compressed into the armed configuration when the handle is moved from the open to the closed position; and a retract button mechanically linked to the injector tube, the retract button causing the injector tube to be locked in a position toward the syringe end of the injector body, unless the retract button is activated.
