摘要：
FIELD: medical equipment.SUBSTANCE: device refers to medical equipment, namely to devices for intramuscular injection, and can be used in medical equipment. Automatic injector for standard medical syringes, consisting of a body, springs, a syringe holder, that platoon plate during the downward movement interacts, until the latch of the syringe lift is snapped under the influence of the physical strength of the human hand, move down to snap the lift lock, plunger of piston is configured to be platted in accordance with the degree of filling of the syringe, rising to the height of the piston rod of the syringe, wherein, piston pusher is configured to platoon according to the degree of filling of the syringe, rising to the height of the piston rod of the syringe, while the rack and the plunger of the piston pusher ensures the fixing of the piston pusher at different heights, wherein a syringe is inserted into the syringe holder, the syringe holder being releasable by the force of the human hand on the trigger button, wherein by means of a main spring cooperating with the syringe holder, the needle of the syringe is inserted into the desired body depth into the patients body, after which the syringe holder, the rack, the piston pusher, the plunger of the plunger of the piston is lowered to its lowest position in the casing, the plunger of the piston being able to be disengaged from the gear rack of the syringe lift bar, thereby permitting the downward movement of the rack bar and the piston pusher, which allows to squeeze injection fluid from the syringe, and after reaching the rack of the latch of the syringe lift, it is possible to release and, under the influence of the lifting spring, raise the syringe and withdraw the needle from the injection site, while the syringe holder, the pusher, syringe lift is set by the longitudinal movement of the guide body.EFFECT: after reaching the rack of the latch of the syringe lift, it is possible to release and, under the influen
