1. A medicament delivery device comprising:
a housing having a longitudinal axis, a proximal end and a distal end;
a plunger rod slidably positioned within the housing such that the plunger rod is axially movable and rotationally fixed relative to the housing, where the plunger rod has a cocked state and a released state;
a carrier axially and rotationally fixed within the housing, where the carrier has a central opening to accept and allow the plunger rod to move distally relative to the carrier when the plunger rod is in the released state; and
a spring having a first end and a second end, where the first end is fixed to a spool that is axially fixed to a proximal end of the plunger rod and where the second end is axially fixed relative to the housing;
wherein the plunger rod further comprises a clicker that engages a tooth axially fixed relative to the carrier when the plunger rod moves through the central opening in the released state such that an audible signal notification is provided to a user of the medicament delivery device.
