Abstract
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.
