Abstract
An injection device comprises: an injection device body; a needle shroud comprising a shroud pin; and a collar rotatable with respect to the injection device body and comprising a cam track. During retraction of the needle shroud, a first portion of the cam track guides the shroud pin to a hold position and cause the collar to rotate relative to the injection device body from a first position to a second position. During a subsequent extension of the needle shroud, a second portion of the cam track guides the shroud pin from the hold position to a final position and causes the collar to further rotate relative to the injection device body from the second position to a third position, the second portion comprising a blocking portion configured to prevent extension of the needle shroud from the injection device body when the collar is held in the second position.
