Abstract
The present disclosure relates to an audible indicator for use with a drug delivery device comprising a resilient force member configured to reside in one of a relaxed state and a biased state. The audible indicator comprises a retainer adapted to maintain the resilient force member in the biased state. The resilient force member releases stored energy to impact a surface to generate an audible signal when the resilient force member changes from the biased state into the relaxed state.

An audible indicator for use with a drug delivery device, the audible indicator comprising:
- a resilient force member configured to reside in one of a relaxed state and a biased state, and
- a retainer adapted to abut a plunger to maintain the resilient force member in the biased state,
- wherein the resilient force member is configured to release stored energy to impact a surface to generate an audible signal when the resilient force member changes from the biased state into the relaxed state.
A drug delivery device, comprising:
- a case,
- a plunger, and
- an audible indicator comprising
- a resilient force member configured to reside in one of a relaxed state and a biased state, and
- a retainer adapted to abut the plunger to maintain the resilient force member in the biased state,
- wherein the resilient force member is configured to release stored energy to impact a surface of the case to generate an audible signal when the resilient force member changes from the biased state into the relaxed state.
A method comprising:
- containing legs of an audible indicator in a notch of a support arm extending from a plunger of an autoinj ector, the support arm arranged such that the support arm extends along a stem of the plunger, wherein the audible indicator is in a biased position,
- moving the plunger from a proximal position to a distal position, and
- emitting an audible signal by disengaging the legs of the audible indicator from the notch of the support arm such that the legs of the audible indicator flex into an unbiased position and contact a case of the autoinjector.
