Abstract: The present invention relates to a medicament delivery device for delivering a number of predetermined amounts of medicament, comprising a body having a proximal and an opposite distal end and extending along a longitudinal axis (L); a medicament container (20) arranged inside said body; a driving mechanism arranged inside said body and configured to act on said medicament container; a manually movable activation member (102) arranged on the distal end the body; a biased actuator member (64) arranged to be movable along the longitudinal axis and through the manually movable activation member (102), said biased actuator member being configured to protrude a predetermined distance from the distal end of the manually movable activation member and configured to interact with said driving mechanism when the biased actuator member is displaced said predetermined distance towards the proximal end of the body for delivering a predetermined amount of medicament; and an actuator guide member (90) arranged in the body and configured to interact with the manually movable activation member (102) and with the biased actuator member (64) such that said actuator guide member (90) can be held in a position within the body and released from said position after a predetermined amount of medicament is delivered; wherein the actuator guide member (90) comprises at least one second guide element (92) adapted to interact with blocking surfaces in at least one group of guide surfaces (76) arranged on the outer circumferential surface of the biased actuator member (64) if said biased actuator member is operated towards the proximal end of the body during displacement of the biased actuator member (64) from the distal end of the manually movable activation member or if said biased actuator member is released during displacement of the biased actuator member (64) towards the proximal end of the body.

Abstract: An actuation mechanism is presented for a medicament delivery device having a plunger rod arranged to act on a stopper of a medicament container, an actuator arranged slidable and connected to the plunger rod for acting on the stopper when said actuator is operated by displacing it in a longitudinal direction of the actuation mechanism, and an activator for activating the actuation mechanism and for setting a dose. The activator having a generally tubular activator sleeve provided with a spirally extending groove on an outer surface, the groove arranged with a length corresponding to the total amount of medicament to be delivered in a number of doses contained in said medicament container, where the groove is provided with an end wall, a stop ring arranged coaxial with said activator sleeve. The activator sleeve arranged with a follower positioned in the groove and the follower arranged to abut the end wall when the total amount has been delivered.
