Abstract

A safety shield for a needle assembly which includes a cover, a mount and a hinge forming a shield body. The shield body defines a cavity in which a needle assembly having a needle and a luer hub is positioned. The mount includes a socket for receipt of the luer hub while the cover includes a retainer for coupling with the needle assembly. A hinge includes a living hinge between the cover and the mount. A tab encloses one end of the mount. Both the cover and the tab are associated with the mount by means of frangible webs to define a sealed body. A flexible tear strip extends over the cavity to fully seal the body.
