The size and shape of the oxygen inhalation channel match the ventilator or the interface of the oxygen inhaler in the prior art. By providing a ventilation hole and an oxygen inhalation channel, it can meet the needs of some patients to use a ventilator or an oxygen inhaler, and save the trouble of changing joints.

Preferably, the axial cross-sectional shape of the sputum-holding cavity is a trapezoid with a wide top and a narrow bottom. By arranging the sputum-holding cavity into the above-mentioned shape, sputum can be drained to the bottom of the sputum-holding cavity, which facilitates the collection of sputum.

More preferably, the bottom of the sputum-holding cavity is provided with a sputum discharge port with a cover. The sputum discharge port can discharge the collected sputum in time.

Preferably, a second baffle to prevent sputum from flowing backward is provided in the sputum-holding chamber. The second baffle is located on the inner wall of the connecting port, and the slope of the second baffle faces the first opening. By setting the second baffle, it is possible to prevent the patient from lying on his side in the sputum cavity. Backflow of sputum.

Compared with the prior art, the beneficial effects of the utility model are:

The artificial nose with a phlegm-holding cavity described in the utility model can block sputum and drain the sputum into the phlegm-holding chamber by setting the first baffle and making the first baffle opposite to the second opening. cavity; the sputum-holding cavity can be separated from the main body of the cavity, which is convenient for cleaning the sputum-holding cavity and the inside of the artificial nose, and further prolongs the use time of the artificial nose.
