Abstract
An injection device for expelling a dose of drug from a held cartridge () is described. A needle shield () is axially movable relative to a base () between a proximal collapsed position and a distal extended position. A needle shield lock comprises a deflectable lock element () operable to prevent the needle shield () from being moved towards the proximal collapsed position. A lock activator () associated with a plunger () exerts an activation force on the deflectable lock element when the plunger assumes a final position. A biasing means () is arranged to act between the lock activator () and the deflectable lock element (), the biasing means () being configured to resiliency transfer the activation force from the lock activator () to the deflectable lock element () to enable the needle shield () to become locked in the distal extended position but only when the plunger () assumes the final position.
