Abstract
A hypodermic syringe has a syringe barrel with opposed proximal and distal ends and a fluid-receiving chamber therebetween. A tip at the distal end has a passage communicating with the fluid-receiving chamber. A needle hub is mounted to the tip and has a needle cannula mounted thereto. The needle hub includes a stop flange projecting radially outwardly therefrom and a locking wall projecting distally. A safety shield is mounted over the syringe barrel for telescoped movement from a proximal position where the needle cannula is exposed to a distal position where the needle cannula is protectively surrounded. Stop blocks on the safety shield engage the stop flange of the needle hub to prevent complete telescoped removal of the safety shield. Locking teeth on the safety shield engage with the locking wall on the needle hub to prevent proximal movement of the safety shield.
