Drug dispenser equipment

Abstract

The invention refers to a drug dispensing device comprising: an outer casing; a drug container; an actuator; a dosing mechanism; an inner casing fitted into the outer casing and functionally linked to the dosing mechanism; a push rod for the drug to flow from the container; and a drive mechanism equipped with a circular spring, fitted into the outer casing along with the inner casing and which can be engaged by means of the push rod to move the push rod depending on the set drug dose. The cylindrical part is equipped with at least one elastic element with a locking lug and is fixed to the outer casing so that the locking lug disengages from one of the radial teeth of the rotating actuator.
