摘要:
Described is a needle safety device comprising a needle hub including an axial stem having one or more grooves, a needle having a distal tip, a needle shield telescopically coupled to the needle hub and including a first aperture for allowing the needle to pass through, and an inner sleeve rotatably coupled to the needle shield and including a second aperture for allowing the needle to pass through. The inner sleeve includes one or more resilient arms adapted to engage the groove. In a first axial position and a first angular position, the needle shield covers the distal tip of the needle and the first aperture is aligned with the second aperture. In a second axial position, the distal tip of the needle is through the first aperture and the second aperture and extends distally beyond the needle shield. In a third axial position and a second angular position, the needle shield covers the distal tip of the needle and the first aperture is not aligned with the second aperture.
