Description

A kind of multi-function ear nose throat examiner

technical field

The invention relates to the technical field of medical instruments, in particular to a multifunctional ear, nose and throat examiner.

Background technique

At present, when the doctor checks the patient's ear cavity and nasal cavity, he holds a flashlight in his hand and only observes directly through the eyes; it is more troublesome to check the oral cavity and throat, and usually holds the tongue depressor in one hand to depress the patient's tongue. Hold the flashlight in the other hand and shine it into the patient's oral cavity and throat for observation, or use the reflector worn on the head to reflect the light into the patient's oral cavity or throat. However, these traditional methods have caused a lot of inconvenience to doctors, and the light from a flashlight or reflector into the mouth is very limited and the angle of irradiation is difficult to control. The brightness of the ear cavity, nasal cavity, oral cavity or throat is not neutral, which is not conducive to clear observation by doctors. The location of the patient's ear cavity, nasal cavity, oral cavity or throat, and the doctor's direct observation through the eyes, which is relatively far away, makes the observation unclear and incomplete, which will lead to the doctor's inaccurate examination and even wrong diagnosis.
