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.Un inyector automático 50 que incluye un alojamiento 52, 236 que tiene una guía 158, un mecanismo de control del accionamiento, un montaje de la transmisión 110, un motor 106, y una fuente de energía. El alojamiento 52, 236 puede incluir además una cubierta del cartucho 72. Un mecanismo de control del accionamiento incluye un tornillo 114, un portador del cartucho 126, 202, un portador del émbolo 138, 194, 226, 242, y uno o más instrumentos de transferencia del control 150, 204, tal como un disco o cilindro.
