[0002] Severe pneumonia is a serious tracheal disease and usually requires the use of endotracheal intubation for treatment. Intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. The respiratory mucociliary system is the first line of defense of the respiratory tract and plays an important role in maintaining respiratory tract humidification and maintaining normal defense function. Therefore, corresponding medical devices are needed to assist in maintaining respiratory tract humidification, thereby achieving a respiratory tract humidification effect.
[0003] However, when using endotracheal intubation to provide patients with oxygen supplementation, airway humidification cannot be performed. The relatively dry oxygen makes the patient's comfort relatively poor. In addition, due to the lack of humidification and warming functions of the oxygen supply pipeline, it is easy for patients to develop complications such as sputum retention and scabs, which is not conducive to the patient's recovery.

[0026] In this embodiment: after adding a certain amount of clean water into the water storage bottle 2, it is installed to the lower end of the cover 1, and the heating coil 4 is started to heat the clean water in the water storage bottle 2, the internal temperature on the temperature display 6 is observed, and the temperature is adjusted by the temperature regulator 5 to a temperature suitable for the patient. The heated clean water is vaporized, and the gas containing water vapor enters the cover 1 upward, and the hot air flow is gathered by the gas collecting funnel 8 inside the cover 1, and is led out from the outlet 7 into the inside of the joint 9, and then transmitted to the three-way pipe 11 through the pipeline 10. At this time, the oxygen interface 12 on the left side of the three-way pipe 11 is connected to the oxygen pipe, and a steady stream of oxygen enters the three-way pipe 11 and merges with the hot air. The oxygen and moisture are mixed and enter the cannula 13, and the cannula 13 is connected to the patient to ensure that the patient will not be too dry during oxygen absorption, improve the patient's comfort, and facilitate the patient's recovery.
[0027] Reference Figure 2 and Figure 3 In a preferred embodiment, the cover 1 is threadedly connected to the water storage bottle 2 via the thread teeth 3 .
[0028] Supplementary explanation: By means of the threaded connection between the cover 1 and the water storage bottle 2, the water storage bottle 2 can be quickly removed, and clean water can be added and cleaned inside the water storage bottle 2.
[0029] Reference Figure 1 and Figure 4In a preferred embodiment, a humidity regulating mechanism is provided at the upper end of the cover 1, and the humidity regulating mechanism is used to adjust the amount of humidification inside the oxygen delivery pipeline. The humidity regulating mechanism includes a joint 9 installed at the upper end of the cover 1, and a slide groove 14 is provided above the left and right ends of the joint 9. A partition 15 is slidably connected inside the slide groove 14. A fixing block 16 is fixed to the side of the lower end of the partition 15 close to the central axis of the joint 9, and a screw rod 17 is threadedly connected to the internal thread of the fixing block 16.

[0030] In the first embodiment, the hot air generated by heating needs to enter the inside of the pipe 10 through the joint 9.

When the moisture output needs to be increased, the transmission shaft 20 is driven by the knob 21 to drive the second bevel gear 19, and then the first bevel gear 18 is driven to cause the screw 17 to rotate, thereby driving the fixed block 16 to move, and synchronously driving the partition 15 to move to both ends inside the slide groove 14. The opening between the two groups of partitions 15 becomes larger, so that the moisture passing range becomes larger, and the moisture content in the oxygen increases. Therefore, the size of the moisture content in the oxygen is adjusted by adjusting the size of the opening between the two groups of partitions 15.
[0031] Working principle: When in use, after adding a certain amount of clean water into the water storage bottle 2, install it to the lower end of the cover 1, start the heating coil 4 to heat the clean water in the water storage bottle 2, observe the internal temperature on the temperature display 6, and adjust the temperature through the temperature regulator 5 to adjust the temperature to a temperature suitable for the patient. The heated clean water is vaporized, and the gas containing water vapor enters the cover 1 upward, and the hot air flow is gathered through the gas collecting funnel 8 inside the cover 1, and is led out from the outlet 7 into the inside of the joint 9, and then transmitted to the three-way pipe 11 through the pipeline 10. At this time, the oxygen interface 12 on the left side of the three-way pipe 11 is connected to the oxygen pipe, and a steady stream of oxygen enters the three-way pipe 11 and merges with the hot air. The oxygen and moisture are mixed and enter the cannula 13, and the cannula 13 is connected to the patient to ensure that the patient will not be too dry during oxygen absorption, improve the patient's comfort, and facilitate the patient's recovery.
