Abstract
An injector device for a pharmaceutical cartridge. The injector device includes a body defining a space for receiving a pharmaceutical cartridge. One or more retention members are disposed on an outer surface of the body. The injector device further includes a plunger rod having a connection member constructed for connection to a piston associated with a cartridge. The plunger rod has one or more receiving members constructed to cooperatively retain the plunger rod on the body in a first position, and to release the plunger rod from the body when the plunger rod is moved to a second position. The plunger rod further includes a surface for engaging a pharmaceutical cartridge positioned within the body of said injector and for moving a pharmaceutical cartridge distally as the plunger rod is moved from its first position to its second position, thereby activating the cartridge.
