Claim Text:
1. A delivery device that has an initial locked position, an intermediate priming position, and a final delivery position, the delivery device comprising: a housing having a proximal end and a distal end; 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 the initial locked position, to release the plunger rod from the initial locked position toward a proximal end of the delivery device to the 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 delivery device to the 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 removable cap at the proximal end of the housing; and a dose setting mechanism, the dose setting mechanism being locked when the delivery device is in the initial locked position; wherein in the initial locked position, the cap prevents axial movement of the shield sleeve toward the proximal end of the delivery device to a second position; removal of the cap enables the first resilient member to move the shield sleeve into the second position; movement of the shield sleeve to the second position releases the dose setting mechanism; and setting a dose with the dose setting mechanism enables the shield sleeve to move from the second position, thereby enabling the delivery device to reach the delivery position.
