Technical Field

[0001] The utility model relates to the technical field of airway humidification, in particular to a multifunctional three-way sleeve for tracheotomy and humidification. Background Art

[0002] Airway humidification. After tracheotomy, the upper respiratory tract completely loses its gas heating, humidification, and filtering functions, and its defense function is weakened. If the artificial airway is not humidified enough during the humidification work, sputum scabs will form on the artificial airway or upper respiratory tract. Once sputum scabs are formed, they can block the bronchi, increase airway resistance, and cause peripheral dyspnea and suffocation. Therefore, airway humidification is very important.
