Multiple medicament cartridge clip and medicament discharging device therefor

A medicament discharging device for use with an expendable medicament cartridge containing clip in which each cartridge includes a container, a dosage of medicament in said container, a hypodermic needle having a sharpened end for penetrating the muscle tissue of a patient and an opposite end through which the dosage of medicament is fed, means for sealingly containing said needle in a sterile condition in cooperating relation with the container and movable wall means at one end of the container operable in response to a discharging stroke operable when moved through a discharging stroke to cause the sharpened end of said 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, said medicament discharging device comprising

• a portable manually engageable housing structure defining a medicament cartridge receiving station,
• a plunger mounted in said housing structure for movement through said 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,
• manually actuatable means for effecting movement of said plunger through an operative cycle, and
• means on said housing structure for detachably securing a clip of the type described in operative relation with the medicament cartridge receiving station of said housing structure such that when said manually actuatable means is manually actuated to effect movement of said plunger through an operative cycle with a medicament cartridge contained within said clip disposed within said cartridge receiving station the movable wall means thereof will be acted upon by said plunger during the discharging stroke thereof 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 combination of a medicament discharging device and an expendable clip containing a plurality of medicament cartridges, each of said cartridges comprising

• a container,
• a dosage of medicament in said container,
• a hypodermic needle having a sharpened end for penetrating the muscle tissue of a patient and an opposite end through which the dosage of medicament is fed,
• means for sealingly containing said needle in a sterile condition in cooperating relation with the container and
• movable wall means at one end of the container operable when moved through a discharging stroke to cause the sharpened end of said 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,
• said medicament discharging device comprising
• a portable manually engageable housing structure defining a medicament cartridge receiving station,
• a plunger mounted in said housing structure for movement through said 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,
• manually actuatable means for effecting movement of said plunger through an operative cycle, and
• means on said housing structure detachably securing a clip in operative relation with the medicament cartridge receiving station of said housing structure such that when said manually actuatable means is manually actuated to effect movement of said plunger through an operative cycle with a medicament cartridge contained within said clip disposed within said cartridge receiving station the movable wall means thereof will be moved through a discharging stroke by said plunger during the discharging stroke thereof 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.
