Abstract

La présente invention concerne un cathéter médical utilisé pour une perfusion ou une évacuation qui est composé d'un tube de perfusion (1) et d'un tube d'évacuation des liquides de déchets (2). Le diamètre extérieur du tube de perfusion (1) est inférieur au diamètre intérieur du tube d'évacuation des liquides de déchet (2). Un trou d'insertion (4) sur la paroi du tube d'évacuation des liquides de déchets (2) permet au tube de perfusion (1) de passer à travers cette paroi. Une extrémité du tube de perfusion (1) est introduite dans la lumière à travers le trou d'insertion (4) et coulisse hors de l'extrémité avant du tube évacuation des liquides de déchet (2) et, passe ensuite dans une cavité anatomique. La partie tête de l'extrémité du tube de perfusion (1) est hémisphérique, ou recouverte de manière étanche par une coupe hémisphérique (7), qui est constituée de matériau souple. L'autre extrémité du tube de perfusion (1) est en dehors du tube d'évacuation des liquides de déchet (2) et agit comme un port de façon à se connecter à un appareil de thérapie ou à un réservoir de liquide afin de perfuser ce liquide de l'extérieur de la cavité anatomique vers cette cavité
