[0023] Specifically, when collecting respiratory sounds, the flexible piezoelectric material 5 preliminarily collects the patient's respiratory sounds, and transmits the collected respiratory sound data to the intelligent data acquisition unit 8 through a wire. The audio amplifier in the intelligent data acquisition unit 8 performs current amplification, power amplification and filtering output processing on the respiratory sound data. The data collector in the intelligent data acquisition unit 8 collects the filtered output data again and transmits the collected respiratory sound data to the computer through a wire. The doctor makes a diagnosis based on the respiratory sound data on the computer.

[0025] Furthermore, an air injection tube 7 is fixedly provided at the upper end of the hood head 1, and an air injection head 11 is provided at the top of the air injection tube 7. The air injection head 11 is connected to the air injection tube 7. A joint 9 is provided at the side end of the silicone cover 6. The air injection tube 7 is connected to the silicone cover 6 through the joint 9. Air is injected through the air injection tube 7 through the air injection head 11, and the air enters the interior of the silicone cover 6 through the joint 9, thereby propping up and expanding the silicone cover 6, and then sealing it with the patient's throat.

The catheter interface 3 is then used to connect to the outside air for ventilation. Air is injected through the air injection tube 7 via the air injection head 11. The air enters the interior of the silicone mask 6 through the joint 9, thereby propping up and expanding the silicone mask 6, thereby sealing it against the patient's throat.

[0029] When collecting respiratory sounds, the flexible piezoelectric material 5 preliminarily collects the patient's respiratory sounds and transmits the collected respiratory sound data to the intelligent data acquisition unit 8 through a wire. The audio amplifier in the intelligent data acquisition unit 8 performs current amplification, power amplification and filtering output processing on the respiratory sound data. The data collector in the intelligent data acquisition unit 8 collects the filtered output data again and transmits the collected respiratory sound data to the computer through a wire.
