DOSE SETTING MECHANISM AND MEDICAMENT DELIVERY DEVICE COMPRISING THE DOSE SETTING MECHANISM

摘要

A dose setting mechanism for a drug delivery device, comprising: a tubular member (10) having a longitudinal track (18) of predetermined length; A dose drum (40) coaxial with the tubular member (10) and axially and rotatably movable relative to the tubular member (10); And a stationary member (90) axially movable relative to the tubular member (10) but rotatably locked and in further axial and subordinate coupling with the dose drum (40), the stop The member 90 includes a track follower 98 that engages with the longitudinal track 18 so that the rotational movement of the dose drum 40 relative to the tubular member 10 can be adjusted to a predetermined, Resulting in maximum axial displacement of the dose drum 40 and the stop member 90 relative to the tubular member 10.
