Abstract
A needle safety device has an outer tube within which a syringe barrel 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 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 staging position, the barrel is inspectable. In a pre-injection position, the cannula extends a first length beyond the outer tube. In a full-insertion position, the cannula extends a second length greater than the first length beyond the outer tube. In a locked position, the cannula is entirely within the outer tube.
