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.
