Abstract

L'invention porte sur une aiguille de perfusion à double ailette avec ensemble de sécurité, cette aiguille comprenant une canule (1), une gaine (6), un tube de perfusion (4), une base (2), une poignée à double ailette (3) et un ensemble de sécurité. L'ensemble de sécurité est un manchon (7) pourvu d'un port avant (71) et d'un port arrière (72) qui communiquent entre eux. Au niveau de la surface de la paroi de l'extrémité arrière du manchon (7) sont formées deux fentes (73) symétriques permettant d'orienter la base de chaque ailette de la poignée (3), et du bord avant de chaque fente (73) au port avant du manchon (7), deux saignées (74) sont formées respectivement dans le sens longitudinal du manchon (7). Après utilisation de l'aiguille de perfusion, tant que l'on tire le tube de perfusion (4), la base (2) de l'aiguille est entraînée dans le port avant (71) du manchon (7), et la base de chaque ailette de la poignée (3) est entraînée dans les deux saignées (74), et lorsque la base de chaque ailette de la poignée (3) est bloquée dans sa fente respective (73), la canule (7) est logée dans l'ensemble de sécurité.
