The plunger rod is released from being axially locked when the activation sleeve is moved towards the second position.

Abstract: A power pack for use with a medicament delivery device is presented having a plunger rod movable along a longitudinal axis; a drive spring operably connected to said plunger rod; a plunger rod sleeve arranged with holding elements for releasably holding said plunger rod with said drive spring in a tensioned state. Signal initiating elements are arranged to said plunger rod; and signal generating elements arranged to cooperate with said signal initiating elements for providing information to a user of a medicament delivery device about the movement of said plunger rod when said plunger rod sleeve has been activated to release said holding elements.

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.

Abstract: A syringe including a barrel, a plunger moveably arranged within said barrel, and a plunger rod for driving said plunger. A first engagement member is arranged at the plunger rod, such that a longitudinal movement of the plunger rod yields a rotational movement of said first engagement member. The first engagement member includes a grooved surface. A second engagement member is arranged at the barrel to engage with said grooved surface of the first engagement member, wherein the first engagement member is arranged to move relative to the second engagement member, such that feedback is given to a user as the plunger rod is moved relative to the barrel for driving said plunger. The first engagement member is arranged at said plunger rod with a predetermined play there between.
