Abstract

Une seringue (1) à sécurité comprend un corps tubulaire (2) présentant une paroi latérale (3) et une paroi terminale (4) définissant une cavité (5), un plongeur (7) défini par une tige (8) et par un piston (10) coulissant de manière étanche au liquide à l'intérieur de la cavité (5), ainsi qu'une aiguille (6). L'aiguille (6) est reliée à un élément de support (7) porté par la paroi terminale (4) du corps (2) de la seringue à l'aide d'un dispositif (27) de transmission d'une charge limitée, lequel permet à l'aiguille de rentrer à l'intérieur du corps (2) lorsqu'elle est soumise à une pression adéquate contre une surface dure; pour ce faire, le piston (10) comprend une paroi terminale perçable (12) et la tige (8) comprend une cavité (35) tournée vers la paroi terminale (12) du piston et destinée à recevoir l'aiguille (6).
