[0002] A bronchoscope is a medical device used for endoscopic examination of the trachea and bronchi. It consists of a flexible tubular device, usually with a camera and a light source, which can be inserted into the trachea and bronchi through the mouth or nose. A bronchoscope mask is a device used for medical purposes to protect the patient's mouth and respiratory tract during bronchoscopy. This mask is usually made of soft material and can cover the patient's mouth and nasal cavity, while leaving an opening for the doctor to insert the bronchoscope for examination.

[0003] The diameter of the connection opening on the surface of some existing inspection covers is usually larger than the diameter of the bronchoscope wire. When the patient coughs, dirt is likely to flow out from the gap at the connection, resulting in poor sealing.
