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 (S) is formed in the inner surface of the outer tube (). A pin () extending radially outwardly from the collar () slidingly engages the track (S). 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.
