  • Needle assembly
    Patent number: 9333306
    Abstract: Disclosed is a safety needle assembly has a needle guard that prevents accidental needle sticks before and after an injection. A locking collar rotates during use as an inner protrusion follows three paths of a track located on the outer surface of a body housing. When the inner facing protrusion is in the third path, it encounters a hard stop and a rotational bias that locks the guard from further retraction and, thus, covers the sharp distal end of the needle.
