Abstract

L'invention concerne un système de protection principalement destiné à éviter les inoculations accidentelles et la réutilisation d'une aiguille. Ledit système comprend quatre éléments, le premier élément (3) protégeant l'aiguille (1) avant son utilisation. Le logement (2) de l'aiguille (2) est conçu de manière conforme à la norme spécifique et reçoit non seulement l'aiguille hypodermique (1) mais également un élément extensible (4) de type soufflet qui permet l'extension de la partie supérieure du logement (2). La libération du mécanisme se produit grâce à la poussée exercée dans la fente située dans la partie intermédiaire du logement de l'aiguille (2). L'extension du soufflet (4) permet à la partie supérieure du logement de protéger de manière sûre la pointe de l'aiguille (1).
