A plural injecting device comprising an outer housing assembly, a plurality of cartridge sub-assemblies, and a corresponding plurality of releasable spring sub-assemblies for effecting a forward movement of the associated hypodermic needle into the user\s muscle tissue and the associated liquid medicament dosage outwardly through the needle, the sub-assemblies being mounted within the outer housing assembly so that as a result of the actuation of one of the releasable spring sub-assemblies the other releasable spring sub-assembly will be actuated so as to insure a substantially simultaneous injection of the plural dosages contained within the device. A safety arrangement in some embodiments provides for selective individual or plural dosage injection.

A plural hypodermic needle and plural spring actuated injecting device comprising outer housing means adapted to be exteriorly manually engaged by a user, actuating means carried by said outer housing means for movement into an actuating position in response to a manual movement by a user with said outer housing means exteriorly manually engaged as aforesaid, a first cylindrical liquid container within said outer housing means, a first hypodermic needle disposed within said outer housing means in a storage position in operative association with said first container, first plunger means within said outer housing means extending into said first container, first spring means operatively associated with said first plunger means within said outer housing means, first releasable means normally retaining said first spring means in a stressed condition within said outer housing means for actuation in response to the movement of said actuating means into said actuating position to effect release of the stressed condition of said first spring means so that the spring force resulting from said release acts upon said first plunger means to move (1) said first hypodermic needle from said storage position to an extended position into the user and (2) liquid within said first container outwardly through said first hypodermic needle into the user; a second cylindrical liquid container, a second hypodermic needle operatively associated with said second liquid container, second plunger means operatively associated with said second liquid container, second spring means operatively associated with said second plunger means, second releasable means normally retaining said second spring means in a stressed condition operable upon actuation to effect release of the stressed condition of said second spring means, safety means operable (1) when in a safety position with respect to both said first and second releasable means to prevent actuation thereof as aforesaid and (2) when removed from said safety position in relation to said first releasable means to permit the actuation of said first releasable means as aforesaid and from said safety position in relation to said second releasable means to permit actuation thereof, and means mounting said second container, said second hypodermic needle, said second plunger means, said second spring means and said second releasable means within said outer housing means in operative relation to one another as aforesaid so that when said safety means is removed from said safety position in relation to said second releasable means the latter will be actuated as a result of the actuation of said first releasable means so that the spring force resulting from the release of said second spring means by said second releasable means acts upon said second plunger means to move (1) said second hypodermic needle longitudinally outwardly into an extended position into the user in generally side-by-side relation to said first hypodermic needle and (2) liquid within said second container outwardly through said second hypodermic needle into said user.
