Abstract
A needle safety device includes a sleeve having proximal and distal portions separated by a radially-inwardly projecting ledge. A ring in the proximal portion is movable between a first position spaced from the ledge, and a second position adjacent to or abutting the ledge. A shield with at least one radially deformable tab receives the syringe and is movable in the sleeve between an initial position with the tab adjacent to or abutting the ledge, an injection position with the tab spaced from the ledge, and a protection position with the tab located distally from the ledge. The tab, during movement between initial and injection positions, deforms inwardly and traverses the inner surface of the ring, and during movement between injection and protection positions, translates with the ring from the first to the second position, and subsequently deforms inwardly and traverses the inner surface of the ring and the ledge.
