1. A drug delivery safety device comprising:
a needle hub including a cannula having a distal tip;
a trigger mechanism comprising a spring connecting the needle hub to a lock clip at a distal end of the needle cannula
a flexible housing surrounding the needle cannula and connecting a Y-clip to the lock clip such that the distal tip of the cannula is exposed;
a body configured to engage the hub, the body including an exterior wall, an inner cavity having a proximal end and a distal end, and the Y-clip disposed within the cavity, the Y-clip including first and second arms having angled surfaces, wherein the first and second arms are held open by engagement with first and second pockets at the distal end of the inner cavity and by distal force exerted by the spring;
wherein a proximally-directed force applied to the lock clip compresses the spring and releases tension on the flexible housing, whereby the first and second arms of the Y-clip are released from the first and second pockets and the Y-clip moves proximally; and
wherein a subsequent decrease in the proximal force applied to the lock clip decompresses the spring and moves the lock clip in a distal direction such that the lock clip covers the distal tip of the cannula.
