摘要：
An automatic injector (50) includes a housing (52, 236) having a guide (158), a drive control mechanism, a transmission assembly (110), a motor (106), and an energy source. The housing (52, 236) may further include a cartridge cover (72). A drive control mechanism includes a drive screw (114), a cartridge carrier (126, 202), a plunger carrier (138, 194, 226, 242), and one or more control transfer instruments (150, 204), such as a puck or cylinder. The drive screw (114) interfaces and connects with the plunger carrier (138, 194, 226, 242). The automatic injector (50) is configured to accept a variety of syringes as cartridges (54, 224) for drug delivery. The cartridges (54, 224) may be ejected from the injector (50) and safely disposed after use, making the injector a reusable automatic injector (50). The reusable automatic injector (50) may further include one or more sensors (160, 165), such as a cartridge sensor (160) and a patient sensor (165). The novel incorporation of the drive control mechanisms into the automatic injectors (50) of the present invention enables a single motor (106) and transmission assembly (110) to drive the function of multiple components, which may include the steps of: preparation and alignment of a cartridge (54, 224) for injection, removal of a safety cap or needle shield (60), needle injection, drug dose delivery, and syringe and/or needle (58) retraction. Methods of manufacture and methods of use are also disclosed.La présente invention concerne un injecteur automatique (50) qui comprend un boîtier (52, 236) ayant un guide (158), un mécanisme de commande dentraînement, un ensemble de transmission (110), un moteur (106), et une source dénergie. Le boîtier (52, 236) peut comprendre en outre un couvercle de cartouche (72). Un mécanisme de commande dentraînement comprend une vis dentraînement (114), un support de cartouche (126, 202), un support de piston (138, 194, 226, 242), et un ou plusieurs instruments de transfert de commande (150,
