A flashback chamber is provided in the housing at or near the distal end of the housing. A shield is hinged to a portion of the housing proximally of the entrance to the flashback chamber. As a result, good visibility of the flashback chamber is achieved, After use, the shield can be rotated into a closed position for surrounding the IV cannula and avoiding accidental needle sticks.1/5 64 78 60 84 70 0 46 62 0 14 10 50 74 58 26-----4 20 762 72 -- -' 18 1 22' 16 36 30 34 FIG. 1 82
