A shield assembly is provided for a needle cannula of a hypodermic syringe. The shield assembly includes inner and outer shield. The inner shield includes aguard selectively movable between a proximal position which permits use of needle cannula and a distal position which safely covers the tip of the needle cannula. The outer shield is frictionally and removably positioned over the needle cannula when the inner shield is in its proximal position. Movement of the inner shield to its distal shielding position enables alignment of cooperating locking structure on the inner shield and outer shield with one another for permanently securely locking the outer shield over the needle cannula.
Un ensemble écran, prévu pour l'aiguille d'une seringue hypodermique, comporte un écran interne et un écran externe. L'écran interne comprend une gaine qui peut passer d'une position proximale, permettant d'utiliser l'aiguille, à une position distale, recouvrant en toute sécurité la pointe de l'aiguille. L'écran externe est placé par friction de façon non permanente par-dessus l'aiguille lorsque l'écran interne est dans sa position proximale. Le déplacement de l'écran interne vers sa position distale permet aux structures verrouillables interdépendantes des écrans interne et externe de s'aligner les unes aux autres afin de bien verrouiller de façon permanente l'écran externe par-dessus l'aiguille.
