[0002] In current medical practice, endoscopy is a commonly used diagnostic and treatment method, especially in the diagnosis of respiratory and digestive system diseases, where fiberoptic bronchoscopes are widely used. When performing an endoscopic examination, it is usually necessary to provide the patient with oxygen while maintaining a clear view of the examination site. The traditional practice is to wear a mask on the patient's face to supply oxygen, and then use a separate dental pad tube to keep the patient's mouth open to facilitate the insertion and operation of the endoscope.

[0003] However, the existing mask and dental pad tube design has several shortcomings. First, the mask and dental pad tube are often not designed as an integrated unit, but are used as two independent components. This makes it difficult to keep the mask and dental pad tube in the same straight line in actual operation, which brings inconvenience to the doctor's operation and may even affect the accuracy and safety of the examination. Secondly, during pressurized oxygen ventilation, the lack of effective sealing between the mask and the endoscope leads to low oxygen ventilation efficiency.

After the gas enters the annular airbag 9, it expands and fits tightly to the gap between the central cavity 6 and the endoscope;

[0067] The spring check valve installed on the exhaust pipe 13 can prevent the gas from flowing back and ensure the correctness of the gas flow direction; when exhaust is required, the ventilation diverter valve switches to the second air pipe 15 to discharge the gas in the annular airbag 9.

[0068] Example 2

[0069] The difference between this embodiment and embodiment 1 is that the air intake and exhaust control component adopts a manual airbag, and the manual airbag is detachably connected to the trachea joint 10. During operation, the annular airbag 9 is supplied with air by squeezing the manual airbag, and the manual airbag is removed to achieve the deflation operation when deflation occurs.
