    depicted in FIG. 1), completed one injection. Further, subsequent injections can be made, and now the piston 15 is already in a different position than originally, since it has moved forward by a distance equal to the amount of substance injected at the first injection.
    In order to carry out a continuous series of consecutive injections, the electronic device 13 is introduced into operation. Then, even with constant pressing of the trigger 14, the current to the electromagnet 8 is intermittently applied and a series of injuries are performed.
    The injector shown in FIG. 2 includes: a housing within which an electromagnet 19 is interposed, interacting with the core 20; bed 21 moving along rails 22; an electric actuator 23 connected via an axis 24, gears 25 and 26, and a screw 27 with a plate 28; a syringe 29 with a piston 30; trigger 31.
    The injector works as follows.
    The trigger 31 is pressed and the current is applied to the electromagnet 19. The bed with the syringe 29 begins to move until it interacts with the stopper 32, which is electrically connected to the electric drive 23. When the stopper 32 is pressed, the circuit closes, the piston 30 moves and enter the required amount of medication. The release of the trigger 31 causes the power supply of the electric drive 23 to stop. The piston 30 and the syringe 29 itself with the bed 21 return to their original position.
    The proposed injector can be performed as a single injection, and a series of consecutive injections at any desired pace.

    Claims (3)
    [1]
    1. An injector comprising a corus, syringe and means for moving the piston, in order to carry out injections in the form of a series of consecutive injections, the syringe is mounted on a bed placed inside the body, which is mounted for reciprocating relative to the body by means of for moving a portable or stand alone drive.
    [2]
    2. The injector according to claim 1, characterized in that the means for moving the piston are made in the form of an electromagnetic actuator.
    [3]
    3. The injector according to claim 1, wherein the autonomous drive is electromagnetic, and the means for moving the piston is an electric drive.
