A cartridge assembly having a cylindrical body, with its forward end being packed down to form an annular flange, a hub fitted on the annular flange, a diaphragm seal positioned on the forward face of the annular flange and held in sealing position by the hub fitted on the annular flange, a piston slidably carried in the rearward portion of the body, a liquid medicament held in the body in the space between the diaphragm and the piston, the hub being made of transparent plastic material and having a first cylindrical portion having an internal diameter sized to fit over the annular flange of the cartridge, a second cylindrical portion extends from the first cylindrical portion and has a diameter less than the first cylindrical portion, a third cylindrical portion extends from the second cylindrical portion and has a diameter less than the second cylindrical portion, a fourth cylindrical portion extends from the third cylindrical portion and has a diameter less than the third cylindrical portion, the fourth cylindrical portion having an internal diameter sized to receive the non-patient end of the needle, the chamber formed by the second cylindrical portion constitutes the chamber for the ballooning of the diaphragm when under medicament pressure, this chamber being provided with a spike having its point directed toward the diaphragm and adapted to pierce same upon sufficient ballooning thereof.

Cartridge with universal plastic hub

An automatic injector training device comprising an automatic injector simulating assembly having a forward end arranged to be engaged with a muscle injection site of the user and an exterior periphery adapted to be manually gripped by a user. The assembly includes an outer structure and a movable structure mounted for movement with respect to the outer structure (1) from a storage position into an audible signal producing position in response to an actuating movement performed by the user while manually gripping the exterior periphery of the assembly and thereby maintaining the forward end of the assembly in engagement with the injection site and (2) from its audible signal producing position into its storage postion in response to a reset movement performed by the user. A safety is provided which is arranged (1) to prevent movement of the movable structure out of its storage position in response to a user actuation movement when the safety is in a safety position (2) to enable the movable structure to be moved from its storage position into its audible signal producing position in response to a user actuating movement when the safety means has been manually moved out of its safety position and (3) to enable the movable structure to be moved from its audible signal producing position back into its storage position in response to a user reset movement.

Audible signal autoinjector training device

A medicament discharging device and an expendable clip thereon containing a plurality of medicament cartridges. Each of the cartridges comprises a container, a dosage of medicament in the container, a hypodermic needle sealingly contained in a sterile condition in cooperating relation with the container and a movable wall means at one end of the container operable when moved through a discharging stroke to cause the sharpened end of the needle to move outwardly out of sealingly contained relation and into the muscle tissue of a patient and the medicament dosage to move outwardly of the container into the opposite end of the needle and out of the sharpened end thereof into the muscle tissue of the patient. The medicament discharging device comprises a portable manually engageable housing structure defining a medicament cartridge receiving station, a plunger mounted in the housing structure for movement through the medicament cartridge receiving station in repetitive operative cycles each of which includes a discharging stroke in one direction and a return stroke in the opposite direction, a manually actuatable mechanism for effecting movement of the plunger through an operative cycle, and a releasable connection between the housing structure and the clip for securing the same in operative relation so that successive cartridges in the clip will be presented in the medicament cartridge receiving station of the housing structure for injection in response to an operative cycle.
