Abstract
Described is a needle safety device comprising a needle hub having a radial protrusion, a needle coupled to the needle hub and having a distal tip, and an inner sleeve telescopically coupled to the needle hub. The inner sleeve includes a first track adapted to engage the radial protrusion. The first track includes an axial section and a radial section. When the inner sleeve is in a first advanced position (PA1) and a first angular position (P1) relative to the needle hub, the radial protrusion is engaged in the first track and the distal tip is covered. When the inner sleeve is in a retracted position (PR) relative to the needle hub, the radial protrusion is in the axial section and the distal tip is exposed. When the inner sleeve is in a second advanced position (PA2) relative to the needle hub and a second angular position (P2), the radial protrusion is in the radial section and the distal tip is covered.
