Abstract:
1. A needle free injector, comprising: a cap comprising an orifice seal covering an injection orifice of the injector; a collar section comprising a trigger blocking mechanism locked rigidly to the cap; an upper sleeve and a medication cartridge; a trigger mechanism; wherein the trigger blocking mechanism, prevents the medication cartridge from moving toward the upper sleeve, thereby preventing delivery; wherein the removal of the orifice seal is mechanically linked to the disengagement of the trigger blocking mechanism; wherein rotating the collar section and trigger blocking mechanism about a longitudinal axis of the injector removes the trigger blocking mechanism thereby placing the injector in a ready to trigger state: wherein the injector is configured such that the injector cannot be placed in the ready to trigger state prior to removal of the cap; wherein the injector is configured so that removing the orifice seal cannot trigger the delivery of the device; wherein the injector is configured such that pressing the delivery orifice against the delivery site triggers the device to deliver; wherein pressing the delivery orifice against the delivery site moves the medication cartridge toward the upper sleeve; and wherein the movement of the medication cartridge toward the upper sleeve forces an aperture in the wall of the upper sleeve into alignment with a component of the trigger mechanism.
