    摘要： An injection device (210) is described. A housing (212) receives a syringe and includes a return spring (226) for biasing the syringe from an extended position in which its needle (218) extends from the housing (212) to a retracted position in which the it does not. A drive spring (230) acts on a first drive element (232) and a second drive element (234) acts upon the syringe to advance it from its retracted position to its extended position and discharge its contents through the needle. The first drive element (232) is capable of movement relative to the second (234) once a nominal decoupling position has been reached. A release mechanism is activated when the first drive element (234) is further advanced to a nominal release position, to release the syringe (214) from the action of the drive spring (230), whereupon the return spring (226) restores the syringe (214) to its retracted position. Decoupling of the drive elements is achieved with a particular form of releasable drive coupling using two pairs of overlying flexible arms (235, 247). A particular form of release mechanism that also uses flexible arms (233) is also envisaged.

    摘要： A needle free hypodermic injector comprising a hand manipulatable elongate housing, an impact impulse injection mechanism within the housing, a suction generating means within the housing and cooperable with the impact impulse injection mechanism, a safety interlock mechanism, at least one medicament containing ampule cooperable with the impact impulse injection mechanism and the suction generating means and having a jet orifice through which medicament is injectable through a skin surface in response to an impulse placed on the medicament by the impact impulse injection mechanism, and means to receive and hold the ampule on the injector in registration with the impact impulse injection mechanism and in communication with the suction generating means; whereby the injector is adapted to expel the medicament from the ampule in a jet stream of sufficient velocity to penetrate skin tissue held against the orifice by the suction generating means and to deposit the medicament intradermally, subcutaneously or intramuscularly based on the position and angle of the jet orifice.

    摘要： The present invention is a hand-operated injector device for injecting parenteral medications consisting of a cap, a plunger, a base, and a snap means. The cap contains a hollow central finger which upon proper hand force, moves toward a narrow plunger with an ability to slide into an annular wide plunger within an self-contained injection capsule. The movement of the cap drives the narrow plunger toward a narrow injection orifice at the bottom the capsule containing liquid medicament through which, the medicament under high pressure, forms a liquid jet through subcutaneous tissue of the patient. The injector may contain an external spring assisted holder or an internal spring assisted holder where the central finger is modified so as to be spring loaded. Finally, the spring injector may contain a cocking tab and a reusable power case. The injector device requires little training to use, reduces pain, improves injection safety and eliminates the need for a check valve.
