Abstract

L'invention concerne une seringue de sécurité à aiguille rétractable comprenant un mécanisme de freinage. Ce mécanisme de freinage peut être disposé au niveau de la partie proximale du corps de la seringue. Ledit mécanisme de freinage peut comprendre un élément de freinage pouvant passer d'une position de freinage à une position relâchée. En position de freinage, les doigts de l'élément freinage viennent au contact d'une surface externe de la tige du piston de la seringue, par frottement. Ce contact par frottement compense une force de rétraction qui sollicite le piston de la seringue vers une position rétractée. Lorsque les éléments de freinage passent à la position relâchée, les doigts n'exercent aucune pression sur la surface externe de la tige. Ainsi, la force de rétraction peut faire passer le piston en position rétractée, et entraîner l'aiguille et le porte-aiguile dans le corps de la seringue.
