Abstract:
1. A multi-use, needle-free injector assembly having a proximal end and a distal end, the distal end having a distal end orifice, an injection piston located generally within an injector lumen, comprising: (a) a removable cap generally distal to the distal end orifice, wherein the distal end orifice is distal to the injector lumen, the cap further including a cap distal face and cap proximal face; (b) an injection prevention component disposed generally proximal to the cap distal face and distal to the distal end orifice; (c) wherein the injection prevention component has a first injection prevention configuration to prevent the injector assembly from administering injectate to a subject at a sufficient pressure to pierce the skin and a second injection permitting configuration to permit the injector assembly to administer injectate to a subject, and (d) wherein the injection prevention component is reversibly movable between the first injection prevention configuration when the cap is removed and the second injection permitting configuration when the cap is in place.
