A shielded needle assembly includes a needle guard slidably movable along a needle cannula from a proximal position where the distal end of the needle cannula (214) is exposed to a distal position where the distal end of the needle cannula is safely shielded within the needle guard (230). A hinged arm assembly connects the needle guard (230) assembly to needle hub. A trigger (250) is articulated to the needle hub at a location proximally of the hinged arm. Distally directed digital forces cause the trigger to rotate such that the trigger urges the hinged arm from a collapsed condition to an extended condition.

Un ensemble aiguille protégé comprend une gaine d'aiguille mobile de manière coulissante le long d'une canule d'aiguille depuis une position proximale dans laquelle l'extrémité distale de la canule (214) de l'aiguille est exposée jusqu'à une position distale dans laquelle l'extrémité distale de la canule de l'aiguille est protégée de manière sûre à l'intérieur de la gaine (230) de l'aiguille. Un ensemble bras articulé relie l'ensemble gaine (230) de l'aiguille à la garde de celle-ci. Une gâchette (250) est articulée sur la garde de l'aiguille au niveau d'un point proximal du bras articulé. Des forces digitales dirigées distalement provoquent la rotation de la gâchette de manière que celle-ci pousse le bras articulé d'une position repliée à une position déployée.
