Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail.

A kind of artificial nose is disclosed as shown in Fig. 1 and Fig. 2, comprises upper casing 12, middle casing 13 and lower casing 14, upper casing 12 communicates with middle casing 13, middle casing 13 and lower casing 14 respectively, the lower casing 14 The outer end is provided with an air inlet 1, and the air inlet 1 communicates with the lower shell 14. The outer end of the upper shell 12 is provided with an air outlet 8, and the air outlet 8 communicates with the upper shell 12. The air inlet 1 and the air outlet 8 communicate with each other through the breathing passage 15. Connected, the air inlet 1 and the air outlet 8 are respectively connected with the patient's breathing circuit, a water inlet 7 is also provided on the outer surface of the upper casing 12, and a heating sheet 6 and a water-absorbing film 5 are also arranged in the middle casing 13, and the heating sheet 6 abuts against the inner end of the water inlet 7, the water-absorbing membrane 5 abuts on the inner surface of the heating plate 6, and the inner end of the air inlet 1 is provided with a filter membrane 2, and the filter membrane 2 is arranged in the breathing passage 15.

A thermal insulation sponge 3 is arranged on the breathing passage 15 of the lower shell 14, and the thermal insulation sponge 3 abuts on the inner surface of the filter membrane 2, and the filter membrane 2 and the thermal insulation sponge 3 form two-layer settings to jointly breathe The passage 15 is completely closed; the outer surface of the lower casing 14 is provided with a detection port 11, which communicates with the air passage 15 of the lower casing 14, and is connected with the detector, and the detector obtains the patient's breathing gas through the detection port 11. The sample is conducive to accurately measuring the patient's disease condition.

The outer surface of the upper shell 12 is provided with a sputum discharge port 9, which communicates with the respiratory passage of the middle shell 13, and is used to access the sputum in the patient's respiratory passage; There is a one-way valve 4, which is used to control the exhaled gas to directly enter the air inlet 1 of the artificial nose, and the exhaled gas can only enter the human body after being heated by the heating plate 6; a cover 10 is also provided at the outer end of the phlegm discharge port 9, It is used to discharge the sputum left in the sputum discharge port 9.
