Each nasal cavity is divided into the nasal vestibule and the proper nasal cavity by the nasal threshold. The front side is connected to the anterior nostril through the nasal vestibule, and the back side is connected to the nasopharyngeal cavity through the posterior nasal foramen.

[0003] During the nasal examination in the ENT department, an examination device is needed to assist medical staff in observing the inside of the nasal cavity. The existing examination device is usually used by connecting a monitor via a camera, but the existing monitor is not convenient for adjusting the angle when in use. When facing examinees of different heights, the doctor needs to adjust his or her posture for observation. Uncomfortable body posture can easily cause discomfort to the medical staff. Therefore, a nasal examination device that is easy to adjust is proposed. Utility Model Content
