An automatic injector apparatus comprising an outer housing assembly, a hypodermic needle, first and second containers, a first liquid medicament ingredient in the first container and a second medicament ingredient in the second container, first and second pistons in the first and second containers

An automatic injector apparatus comprising an outer housing assembly, a hypodermic needle, first and second containers, a first liquid medicament ingredient in the first container and a second medicament ingredient in the second container, first and second pistons in the first and second containers respectively, a releasable stressed spring arrangement capable of being released twice, once for movement through a first piston moving stroke and second through a second piston moving stroke, a first releasing device operable in response to a first predetermined actuating procedure for accomplishing a first release of the spring arrangement so as to effect movement of the first piston through a liquid medicament ingredient moving stroke causing the liquid medicament ingredient to mix with the medicament ingredient in the second container to form liquid medicament and a second releasing device operable in response to a second actuating procedure for accomplishing a second release of the spring arrangement so as to effect movement of the second piston through an operative stroke causing the hypodermic needle to be moved into the muscle tissue of the patient and the liquid medicament to be moved through the needle into the muscle tissue of the patient.

An automatic injecting apparatus comprising an outer housing assembly including therein first and second medicament ingredient containers, a hypodermic needle disposed within said outer housing assembly for movement from a storage position in a sterile condition outwardly of said outer housing assembly into the muscle tissue of a patient for passage of liquid medicament therethrough and into the muscle tissue of the patient, a first liquid medicament ingredient in said first container, a first piston mounted in said first container in a storage position in sealingly retaining relation with respect to said liquid medicament ingredient therein for movement from said storage postion relatively through said first container in a liquid medicament ingredient moving stroke, a second medicament ingredient in said second container, a second piston mounted in said second container for movement from a liquid medicament moving position through said second container in a liquid medicament discharging stroke, spring means disposed within said outer housing assembly in a storage position in a releasable stressed condition capable of being released twice, first to move through a first piston moving stroke causing said first piston to move through its liquid medicament ingredient moving stroke and second to move through a second piston moving stroke causing said second piston to move through its liquid medicament discharging stroke, first releasing means operable in response to a first predetermined manual actuating procedure for effecting the first release of the stressed condition of said spring means, means operable when said first piston is moved through its liquid medicament ingredient moving stroke by the first release of the stressed condition of said spring means for causing the first liquid medicament ingredient discharging from said first container to flow into said second container to mix with the second medicament ingredient contained therein to form liquid medicament, and second releasing means operable in response to a second predetermined manual actuating procedure for effecting the second release of the stressed condition of said spring means so as to cause said second piston to move through its liquid medicament discharging stroke during which said hypodermic needle is moved into the muscle tissue of the patient and the liquid medicament is moved through said needle into the muscle tissue of the patient.
