Medicament delivery device with delivery finish signal delay

A medicament delivery device extending along a longitudinal axis and comprising:

• a housing having a distal and a proximal end, said housing being adapted to receive a medicament container;
• a drive mechanism comprising a plunger rod driver movable in said housing between biased and released positions and arranged to act on a plunger rod, which plunger rod in turn is arranged to act on the medicament container;
• a hold-release mechanism interactively connected to the drive mechanism for holding the drive mechanism in the biased position and releasing the drive mechanism from the biased position;
• and
• a delayable signal generating mechanism comprising a signal generating element interactively connected to the drive mechanism, where
• the delayable signal generating mechanism is releasably connected to the hold-release mechanism such that when the plunger rod nears or reaches the end of its operating stroke, the delayable signal generating mechanism is released from the hold-release mechanism whereby the delayable signal generating mechanism is enabled to interact with the drive mechanism for generating an audible and/or tactile and/or visual signal indicating that a medicament has been completely delivered,
• wherein said plunger rod driver is operably arranged to said plunger rod via said signal generating element.
