Abstract:
1. A medicament delivery device having an initial locked state, an intermediate priming state, and a medicament delivery state, the medicament delivery device comprising: a housing having a proximal end and a distal end; a medicament container holder arranged within the housing; a plunger rod arranged within the housing; a plunger locking device rotatable in relation to the housing and to the plunger rod and configured to hold the plunger rod in an initial locked position in the initial locked state, to release the plunger rod from the initial locked position toward a proximal end of the medicament delivery device to an intermediate priming position, to hold the plunger rod in the intermediate priming position, and to release the plunger rod from the intermediate priming position toward the proximal end of the medicament delivery device to a final delivery position; a shield sleeve slidably arranged at least in a proximal part of the housing; a first resilient member associated with the shield sleeve; a cap assembly at the proximal end of the housing and connected to the medicament container holder, the cap assembly comprising a removable outer cap; and a dose setting mechanism being locked in the initial locked state; wherein in the initial locked position, the cap locks the shield sleeve from axial movement toward the proximal end of the medicament delivery device to a second position; the shield sleeve, when moved into the second position by the first resilient member upon removal of the outer cap, is locked in the second position by the plunger locking device; movement of the shield sleeve to the second position results in release of the dose setting mechanism; and setting a dose with the dose setting mechanism releases locking of the shield sleeve in the second position, thereby enabling medicament delivery.
