摘要:
The present invention is generally directed to a clicker arrangement for use in a drug delivery device and a drug delivery device comprising such a clicker arrangement. The arrangement comprises a first, rotatable element (60) and a second, non-rotatable element (110). One of the first element (60) and the second element (110) comprises a clicker arm (67) and the other of the first element (60) and the second element (110) comprises a cam (117). Upon relative rotation of the first element (60) and the second element (110) the clicker arm (67) is elastically deflectable by the cam (117) and relaxable upon disengagement with the cam (117) thereby generating an audible and/or tactile feedback signal. The arrangement further comprises a third, axially movable element (40) having a ramp (47) for interaction with the clicker arm (67), wherein, when the third element (40) is in a first axial position, the ramp (47) does not interact with the clicker arm (67), which in turn prevents the clicker arm (67) from contacting the cam (117), and when the third element (40) is in a second axial position, the ramp (47) deflects the clicker arm (67) such that the clicker arm (67) contacts the cam (117).
