Detailed ways

The present utility model will now be described in further detail in conjunction with the accompanying drawings.

As shown in Figures 1-2, a high-flow humidification device for artificial airway patients includes a humidification tank 1, a water inlet pipe 2, an air inlet pipe 3 and an air outlet pipe 4, the humidification tank 1 and the ventilator heater Connection, the top inner wall of the humidification tank 1 is provided with a positioning pipe 9, the end of the water inlet pipe 2 passes through the humidification tank 1 and is located in the positioning pipe 9, and a water level plug 8 is provided below the water inlet pipe 2. The water level plug 8 is provided with a column 10, the column 10 is located in the positioning pipe 9, the intake pipe 3 extends through the top of the humidification tank 1 to the bottom of the humidification tank 1, and an air-oxygen mixer 21 is arranged on the top of the intake pipe 3. The air-oxygen mixer 21 is connected to the oxygen source pipe 15 and the air source pipe 14. The air outlet pipe 4 is arranged on the top of the humidification tank 1 and communicates with the interior of the humidification tank 1.
