Abstract
A medical device includes a barrel with proximal and distal ends. A needle extends from the distal end of the barrel and terminates in a point. A shield is coaxially and rotationally mounted on the barrel. This shield is axially movable between a retracted position in which the needle point is exposed and an extended position in which the needle point is covered. The device includes locking elements associated with the barrel and the shield. These locking elements are responsive to a combined rotational and axially distal movement of the shield, when the shield is at an extended and unlocked position, for locking the shield on the barrel at the extended position. These locking elements prevent subsequent rotational and axial movement of the shield on the barrel.
