Tracheal ventilation device, in particular tracheal tube, which seals the trachea in as air-tight a manner as possible. Said device comprises a cuff that blocks the trachea below the glottis and is traversed by a ventilation cannula. The cuff is larger in its filled, freely displaceable, unrestricted state than in its filled state positioned in the trachea. The cuff consists of a flexible soft film material and lies against the trachea by means of its folds. The device (1) is adapted to the morphology of a child's larynx and is available in finely graded sizes.

L'invention concerne un dispositif de respiration trachéale, notamment un tube trachéal, qui obture le plus hermétiquement possible la trachée, pour permettre à un patient de respirer, et qui comporte un ballonnet bloquant la trachée au-dessous de la glotte. Une canule de respiration est introduite à travers ce ballonnet. Lorsque ce dernier se trouve dans un état gonflé, dans lequel il peut se déployer librement, sans limitation, il est plus grand que lorsqu'il se trouve dans un état gonflé, une fois mis en place dans la trachée. Ce ballonnet est constitué d'une feuille souple et prend appui, par ses plis, sur la trachée. Ce dispositif (1) est adapté à la morphologie du larynx d'un enfant et est disponible dans des tailles finement échelonnées.
