摘要：
A needle safety device has an outer tube within which a syringe barrel from which a cannula extends is slideably receivable. A collar in the outer tube is moveable relative thereto and rotatably attachable to the distal end of the barrel. A force member biases the outer tube in a distal direction. A cannula shield able to receive the cannula therein is in the outer tube. The cannula shield is fixedly attached to a cap removably attached to the outer tube. A track is formed in the inner surface of the outer tube. A pin extending radially outwardly from the collar slidingly engages the track. In a pre-injection position, the cannula is entirely within the outer tube. In a full-insertion position, the cannula extends beyond the outer tube. In a locked position, the cannula is irreversibly retained entirely within the outer tube.
