Life-size model for oral tracheal and nasal tracheal intubation. In addition to the movable lower jaw, it also places great emphasis on faithfully replicating the nasal, oral, and pharyngeal cavities. When practicing transnasal endotracheal intubation, carefully insert a tube into the nostril and push it carefully along the lower nasal passage and the back wall of the throat to the 7cm mark to ensure that the tip of the tube stops shortly before the epiglottis. Without putting any pressure on the upper jaw, use the laryngoscope scraper held in the left hand to gently lift the base of the tongue until the entrance to the esophagus and the glottis can be seen. Hold the Magill forceps in your right hand, then take out the tip of the tube and insert about 1.5 cm into the trachea through the glottis. We recommend that to prevent the tube from accidentally falling off, place the tube in the vestibule of the nose with the thumb and index finger of the left hand, and place the remaining fingers and palm on the left side of the temple and on the forehead. Newborn baby. The tube can then be attached to the skin as usual (using tape, for example). When the trachea is visible during oral tracheal intubation, the tube can be directly introduced into the trachea through the oral cavity.
