Abstract
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.
