Abstract

A resettable display of a device for metered administration of a fluid drug, comprising a housing, a fluid container containing the fluid and provided in or on said housing, an actuating device shiftably mounted by a length in or on said housing, which, upon actuation, shifts a piston in the fluid container in order to displace from the fluid container a fluid dose adjusted by the actuating device, a display provided in or on said housing displaying a measure for the adjusted fluid dose, and a resetting means shifted with the actuating device and thus resetting the display. The display comprises a minimum of one counter ring rotated from a zero position when adjusting the fluid dose by means of the actuating device in relation to the housing. The resetting means mechanically transfers the shift movement of the actuating device into a reverse rotary movement of the counter ring towards its zero position (FIG. 1).
