摘要：
A drug delivery device for selecting and dispensing a number of user variable doses of a medicament includes a housing having an opening, a dose selector operable to set a dose by rotation relative to the housing, a release member controlling movement of a piston in a dispensing direction, and a display comprising a units number wheel and a tens number wheel which are coupled to each other such that a continuous rotation of the units number wheel is translated into an intermittent rotary motion of the tens number wheel. The release member rotates, during dose dispensing, an angle corresponding to the dose set by the dose selector, thereby allowing a piston to move in a dispensing direction.
