Abstract

L'invention concerne un tube de trachéotomie permettant l'utilisation d'une canule externe inversée en forme de L. Ce tube permet également de réduire la quantité d'écoulement adhérent. Le tube selon l'invention comprend une canule tubulaire externe (1) et une canule tubulaire interne (2) insérée dans la canule externe. La partie pointe (21) et la partie base (23) de la canule interne (2) sont généralement allongées de manière linéaire. La partie courbe (22) de la canule interne est formée de sorte à présenter une forme généralement arquée. Des entailles (211) sont formées sur la surface côté extérieur, au niveau de la partie pointe (21). Elles sont formées de sorte à être généralement fermées lorsque la partie pointe (21) est contenue dans la partie pointe (11) de la canule externe (1), et de sorte à pouvoir également être ouvertes ou fermées. Lesdites entailles (221) sont formées sur la surface côté intérieur, au niveau de la partie courbe (22). Ces entailles (221) sont formées pour être généralement fermées lorsque la partie courbe (22) est contenue dans la partie courbe (12) de la canule externe (1), et de sorte à pouvoir également être ouvertes ou fermées.
