The bottom of the gas-water separation bottle is provided with a drain hole which is of a blind hole structure, a drainage mechanism opened by hydraulic pressure is arranged in the drain hole, and a drain pipe is fixed on the side wall of the drain hole to drain away excessive sterilized water so as to prevent the sterilized water from entering the nasal cavity of a patient and causing asphyxiation.

The drainage mechanism comprises a piston and a spring, the piston is connected with the drain hole in a sliding and sealing mode, a hole shoulder is arranged in the drain hole, and the spring is arranged between the piston and the bottom of the drain hole, so that the piston abuts against the hole shoulder, and the drainage mechanism opened by hydraulic pressure is constructed.

The drainage mechanism is opened when the filling capacity of the sterilized water in the gas-water separation bottle reaches 50-70% of the total capacity of the gas-water separation bottle, and the proper liquid level height is maintained.

The gas circuit is firm and reliable in connection because the plurality of barbs are arranged at the connection parts of the first pipe and the second pipe with the gas-water separation bottle.

And a fixer is arranged on the third pipe, so that the size of the third pipe can be conveniently adjusted according to the head diameter of a patient.

The beneficial effects of the utility model reside in that:

compared with the prior art, the gas-water separation bottle with the weight block is arranged, so that when the humidification bottle is inverted, the sterilized water directly enters the nasal cavity of a patient through the pipeline to cause asphyxiation, and the redundant sterilized water overflows into the gas-water separation bottle to play a role in preventing asphyxia; the weight heavy block ensures that the gas-water separation bottle is always in a vertical state with the bottle bottom downward, so that the gas-water separation bottle is prevented from being too light and inverted under the condition that a pipeline is pulled. Through set up drainage mechanism in gas-water separation bottle bottom, drain away too much sterile water, avoid sterile water to get into the patient nasal cavity and lead to stifling. Through set up the barb on first pipe and second pipe, guarantee that gas circuit firm in connection is reliable.
