Abstract
The present disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing (), a dose selector () operable to set a dose by rotation relative to the housing (), a number sleeve () arranged within the housing () such that at least a portion of the number sleeve () is visible through a first aperture () in the housing (), and a piston rod () coupled to the housing () and to a drive sleeve (). Rotation of the drive sleeve () relative to the housing () causes the piston rod () to translate relative to the housing (). The piston rod () is coupled to the housing () via a threaded interface () with at least two different pitches.
