Abstract

L'invention concerne une seringue équipée d'un corps creux, d'un piston monté coulissant dans ledit corps et d'une aiguille montée à une première extrémité dudit corps. Un premier élément d'étanchéité, à une première extrémité du piston et à l'intérieur du corps, s'appuie coulissant en étanchéité contre ledit corps. Un second élément d'étanchéité s'appuie en étanchéité contre le corps et de manière coulissante contre l'arbre du piston, le second élément d'étanchéité étant placé entre le premier élément d'étanchéité et une seconde extrémité opposée du corps. La poussée du piston dans le corps crée un vide entre le premier et le second éléments d'étanchéité, ce qui permet de pomper le liquide dans la seringue en vue de l'injection. Dans un mode de réalisation, le vide peut servir pour rétracter automatiquement l'aiguille dans le corps, si le piston est d'abord poussé selon une dose suffisante. Une partie du piston se brise aisément après usage, rendant impossible la réutilisation de la seringue.
