Abstract: There is provided an actuation counter comprising a driver feature having one or more driver elements, which driver feature is arranged for drivable movement in response to an actuation; and a count member including one or more drive receipt elements arranged thereon for receipt of drive from said one or more driver elements of the driver feature for drivable movement of the count member. The driver feature includes one or more brake elements arranged to selectively interact with the count member to prevent overrun thereof when registering a count of an actuation. The actuation is suitably arranged for use with a drug dispenser device.

Abstract: A dose counter for use with a medicament dispenser which comprises a ratchet; a first count wheel arranged to rotate about a first axis of rotation, the first count wheel including one or more ratchet drive receipt elements arranged thereon for receipt of drive from the ratchet to rotate the first count wheel about the first axis of rotation; a second count wheel arranged to rotate about the first axis of rotation, the second count wheel including a set of teeth arranged annularly thereon; and a kick wheel arranged to rotate about a second axis of rotation offset from the first axis of rotation, the kick wheel including a set of kick teeth arranged annularly thereon and in meshed relationship with the teeth of the second count wheel such that rotary motion of the kick wheel results in rotary motion of the second count wheel is described.
