The heating base plate 2 is used to control the temperature of the humidification nebulization liquid inside the humidification nebulization host 1. The interior of the liquid storage bag 7 is sterile water for humidification and nebulization. The humidification nebulization host 1 pumps the sterile water into it through the liquid inlet pipe 5. The first oxygen supply pipe 4 and the second oxygen supply pipe 9 are connected to the external oxygen supply equipment. The first oxygen supply pipe 4 can increase the oxygen content of the gas transported to the inside of the delivery pipe 6. The oxygen sensor 8 can adopt the oxygen battery in the prior art, specifically the medical oxygen battery, also known as the oxygen sensor 8, which adopts the electrochemical principle and can be used to detect the oxygen concentration.
