Abstract

The disclosure relates to a drug delivery device including a plunger disposed within a case and an audible indicator that comprises a resilient element. The plunger is slidable from a proximal position to a distal position within the case and the resilient element is in a first configuration when the plunger is in the proximal position, such that the resilient element is deflected radially outwards to a second configuration during movement of the plunger from the proximal position towards the distal position. The resilient element moves from the second configuration towards the first configuration when the plunger moves towards or reaches the distal position, thereby generating an audible and tactile signal.
