Claim 0:
1. A medicament delivery device comprising:
a distal housing;
a proximal housing connected to the distal housing;
a first driver positioned within the distal housing and configured to rotate relative to the distal housing and the proximal housing;
a plunger rod rotatably fixed to the first driver, where the plunger rod rotates during delivery of medicament from a container positioned within the proximal housing; a manually movable activation member positioned on a distally directed end surface of the distal housing, rotatable relative to the distal housing and comprising a grip member arranged on an outer surface;
a biased actuator member comprising a manual actuator extending from a distal end of the biased actuator member and extending through the manually movable activation member such that the manual actuator protrudes distally outward from a distal end of the manually movable activation member when the manually movable activation member is rotated causing the biased actuator member to move distally a predetermined distance relative to the distal housing; and
an actuator guide member rotatably fixed to the manually movable activation member;
wherein axial movement of the manual actuator relative to the distal housing in a proximal direction through the predetermined distance causes rotation of the plunger rod and a delivery of a dose of medicament from the container; and
further comprising a lock element that locks the biased actuator member in a position within the distal housing to indicate a predetermined dose of medicament has been delivered.
