Problems solved by technology

[0003] However, head mirrors and otoscopes have the following shortcomings: 1. The viewing angle is limited; 2. It is impossible to observe the lesion at close range; 3. It is impossible to digitize the observed things
[0005] 1. Due to the huge image display system, the traditional otolaryngoscope can only be used in the laparoscopic examination room and operating room of the hospital. It has no conditions for use in outpatient clinics and is inconvenient to move. Therefore, outpatient doctors can only ask patients to have an examination in the laparoscopic room.
[0006] 2. Traditional ENT mirrors must be disinfected under high temperature and high pressure or soaking before use, and the minimum disinfection time should not be less than half an hour
There are many outpatients. After one patient’s examination is completed, the other often has to wait for a long time for the examination. Some patients even need to make an appointment several days in advance before it may be their turn to be examined. The timeliness is very poor.
[0007] 3. Fogging: Because there is a large amount of human body water vapor in the nasal and throat cavity, the surface of the optical image transmission mirror of the traditional speculum is easy to condense water vapor and form a fog layer. Therefore, it is heated to about 60 degrees before use with normal saline ( The soaking solution cannot be reused) Soak the lens body for more than ten minutes before entering the human body for observation, but fogging cannot be avoided after the temperature of the lens body drops over time; another anti-fog method is the use of anti-fog agents, but the price Expensive, costly to use, and inconvenient
[0008] 4. When some patients are undergoing tracheal intubation, due to the special structure of the patient's own airway or the presence of foreign bodies in the trachea, the difficulty of intubation increases. At this time, the help of a visual laryngoscope or bronchoscope is needed, but the current market The price of these two products is very high, and the utilization rate of the department is very low, so there has not been a device with an appropriate price that can meet the needs of use
