摘要：
A needle shield includes a body extending along a longitudinal axis, and having a longitudinal channel configured to receive a syringe. The body has injection and protection positions. A first latching mechanism on the body is radially outwardly deflectable and includes a protuberance extending radially into the channel. A second latching mechanism disposed on the body and proximally of the first latching mechanism is radially outwardly deflectable and includes a tab at a proximal end thereof extending radially into the channel. The tab has a radially inwardly tapering portion toward a proximal edge of the tab oriented generally perpendicularly with respect to the longitudinal axis. In the injection position, an annular ring on the syringe is located distally of the protuberance, and in the protection position, the proximal edge of the tab is in facing engagement with the annular ring to prevent proximal movement of the body on the syringe.
