Claim 17:
18. A feedback mechanism for an injection device having, the feedback mechanism comprises:
an activation member having a distal end surface;
a plunger rod operatively connected to the activation member, where the plunger rod has a proximal end and is configured to move proximally relative to the activation member when the injection device is activated;
a button operatively associated with the activation member and having an inner surface; and
wherein axial displacement of the button causes activation of the feedback mechanism such that a second audible or tactile signal is generated when an injection is completed,
wherein a first audible or tactile signal is generated when the injection has started and is caused when the proximal end of the plunger rod strikes a stopper slidably positioned within a medicament container positioned within the injection device, and
wherein the second audible or tactile signal is generated when the injection is completed and is caused by the activation member moving from a first position to a second position such that the distal end surface hits the inner surface of the button.
