摘要：
FIELD: medicine.SUBSTANCE: invention relates to automated injectors such as automated medical injectors, and particularly to rechargeable automated injectors that may be capable of supplying one or more individual doses from a medicament cartridge or a prefilled syringe containing a medicament. The rechargeable automated injector for adrenaline injection has a housing to accommodate a syringe with a needle, a piston rod, piston rod tube, a syringe, an actuator, a piston rod actuator and a recharge mechanism. The syringe is located in the housing for movement between the first position in which the needle is positioned within the housing and a second position in which the needle protrudes outwardly from the housing. The piston rod is made to advance in the syringe to deliver at least one dose of medicament. The piston rod tube has two or more deflectable locking elements provided for engagement with the piston rod stopper for piston rod locking with the piston rod tube in the normal state. The syringe actuator is made for force application to the syringe thereby moving the syringe from the first position to the second position. The syringe actuator is also configured to advance the piston rod tube with the piston rod to the second position. The piston rod actuator is configured to apply force to the piston rod to advance the piston rod in the syringe for delivery of one dose of medicament after each of the two or more deflectable stoppers are released. The recharge mechanism is configured to retract the syringe from the second position to the first position and to recharge the syringe actuator for re-activation of the syringe actuator. The recharge mechanism is configured to release the first deflectable stopper after the first movement of the syringe from the first position to the second position, thus freeing the piston rod from the piston rod tube to supply the first drug dose, and release the other deflectable stopper after another movement of the syringe from th
