A, Method of preparation and location of the 2 cross-holes on the plastic bag. The hole sizes and their placement on the plastic bag. Each hole is 3 cm, which is the same size as the connection for the facemask. The distance between the 2 holes is 5 cm. B, The outer hole (red circle) is put on the inner hole (black circle) crosswise. An endotracheal tube can be passed through the center of the cross-hole (yellow cross). C, Just before extubation. The endotracheal tube must be removed in the caudal direction because the outer hole is created caudally to the inner hole, thus providing the greatest effectiveness of the double barrier structure. D, Just after extubation. The outer hole can automatically move in the caudal direction (from the dotted red circle into the red circle) just after extubation because of the shape memory of the plastic bag.
