  • Publication number: 20230074677
    Abstract: A drug injection control device has a structure in which a rod lock screw-coupled to an outer circumferential surface of a piston rod can only make a linear motion under restricted rotation in a rod holder with the rotation of a rod guide and the sub-linear motion of the piston rod. When an injection amount of drug is preset through an injection amount setting module configured to make a rotational motion with a dose dial in a housing to set the amount of drug to be injected by storing the twisting moment in a torsion spring, a button plate is fixed and positioned in the dose dial to perform a function of supporting a button spring, and an injection button is slidably coupled through the button plate, so the injection button rotates simultaneously with the rotation of the dose dial, but allows a stable pushing operation through the button plate.
