Abstract
The present specification relates to a drug delivery device including a housing adapted to receive a primary container with a piston, a plunger slidably disposed in the housing and adapted to drive the piston for delivering a medicament, a drive spring pre-loaded between the housing and the plunger so as to urge the plunger in a distal direction, an audible and/or tactile indicator, and a trigger mechanism arranged between the indicator and the plunger. The trigger mechanism is configured to support the indicator in an initial state of the device and during delivery of the medicament and to couple with the plunger to activate the audible and/or tactile indicator at or near an end of delivery.
