\ A safety shield is provided for a medical implement having a needle cannula. The safety shield includes a guard 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 safety shielded. A hinged arm connects the guard to a hub of the needle cannula or to the medical implement with which the needle cannula is used. The hinged arm can be collapsed upon itself, such that the guard is adjacent the hub of the needle cannula. Alternatively, 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. A spring may be provided to assist movement of the guard toward the distal shielded position.

Protecteur d'instrument médical comportant une aguille cathéter. Le protecteur comprend une gaine qui peut se déplacer en coulissant le long de l'aiguille cathéter pour passer d'une position proximale, dans laquelle la pointe de l'aguille est exposée, à une position distale, dans laquelle la pointe de l'aiguille est recouverte. Un bras articulé relie la gaine à un embout de l'aiguille cathéter ou à l'instrument médical avec lequel un utilisateur se sert de l'aiguille cathéter. Le bras peut se replier sur lui-même de sorte que la gaine est adjacente à l'aiguille cathéter. Dans un autre aspect, le bras peut être étendu pour faire déplacer la gaine distalement le long de l'aiguille cathéter de façon à protéger la pointe de l'aiguille. Un ressort peut également être prévu pour faciliter le déplacement de la gaine vers la position distale de protection.
