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 00 46 62 0 14 10 50 7426-- 40 26 -- --- ,-. 20 . 76-,., , 2 7 2 ,- - 18 12 22 16 .36 30 34 FIG. 1 82
