[0007] Preferably, the exhaust plate and the humidification bottle are an integrally formed structure.

[0008] Preferably, a polymer foam material is arranged under the exhaust plate.

[0009] Preferably, the bottom end of the air inlet pipe is in contact with the polymer foam material.

[0010] Preferably, the polymer foam material is arranged in a circular structure with a thickness of 3-5 cm.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the disposable humidified nasal oxygen cannula is provided with a polymer foam material under the exhaust plate, and the bottom end of the air inlet pipe is in contact with the polymer foam material. The polymer foam material can reduce the bubble noise on the one hand, and can also play a filtering role; moreover, the exhaust holes are evenly distributed on the exhaust plate, and large oxygen bubbles are separated into small bubbles, so that the oxygen is humidified evenly and fully, and the bubble noise is further reduced, so as to avoid affecting the patient's rest during use.
