A needle shield is provided for a medical device having a needle cannula. The needle shield includes a guard (40) that is slidably movable along the needle cannula from a proximal position where the tip of the needle cannula is exposed to a distal position where the tip of the needle cannula is shielded. A hinged arm (51) connects the guard to the proximal end of the needle cannula. The hinged arm can be collapsed upon itself, such that the guard is adjacent to the proximal end of the needle cannula. The hinged arm can be extended to cause the guard to move distally along the needle cannula and into a position for shielding the tip of the needle cannula. Structure is provided to prevent excessive additional rotation of the hinged elements of the hinged guard after the tip of the needle cannula is shielded.

L~invention concerne une protection d'aiguille montée sur un appareil médical à canule-aiguille. La protection d'aiguille comprend une garde (40) qui est mobile en glissant le long de la canule-aiguille depuis une position proximale où la pointe de la canule-aiguille est exposée à une position distale où la pointe de la canule-aiguille est protégée. Un bras (51) à charnière connecte la garde à l'extrémité proximale de la canule-aiguille. Le bras à charnière peut être replié sur lui-même, de façon à ce que la garde soit adjacente à l'extrémité proximale de la canule-aiguille. Le bras à charnière peut s'étendre pour permettre à la garde de se déplacer distalement le long de la canule-aiguille jusqu~à une position protégeant la pointe de la canule-aiguille. Une structure permet d~empêcher une rotation supplémentaire excessive des éléments à charnière de la garde à charnière une fois la pointe de la canule-aiguille protégée.
