Abstract
An injection device having an outer housing configured to receive a syringe. The syringe has a barrel for containing medicament and a needle in fluid communication with the barrel. The device further has a needle shield axially moveable relative to the outer housing between a needle covering position and a needle exposing position and a helical compression spring to bias the needle shield axially forwardly toward the needle covering position. A locking sleeve, axially movable relative to the outer housing between a non-locking position and a locking position, selectively limits axial movement of the needle shield. In a first configuration, the needle shield is axially slideable within the locking sleeve to permit rearward axial movement of the needle shield from the needle covering position to the needle exposing position.
