Antifogging and disinfection-free portable endoscope for examining nose and throat

Abstract

The invention discloses an antifogging and disinfection-free portable endoscope for examining nose and throat. The handheld endoscope comprises an endoscope handle, an adjustable endoscope body and a disposal casing; the endoscope handle can be separated or combined with the endoscope body; the endoscope body with different radial angles can be replaced at any time according to the requirement; and the casing is disposable, so that the endoscope is free from being especially disinfected without the risk of cross infection and can be used at any time. Hot air current is led to the front end ofthe casing and sprayed to the outer surface of a glass sheet, and meanwhile, the surface temperature of the endoscope body is consistent with the temperature of human body by using the heat generatedby an electrothermal film, so that the invention plays a role of eliminating a fog layer. The invention overcomes the defects that the traditional classical endoscope for nose and throat cannot be used under the condition of outpatient services, requires high-temperature disinfection and is easy to generate fog, can be used for doctors in otolaryngological departments to replace different radial angles for observing the pathological conditions of the inside of the nose and the throat part in the outpatient services at any time, and has the advantages of low cost, definite image as well as lightness, smallness and portability of the whole system.

Description

technical field [0001] The invention relates to medical instruments, in particular to ENT medical instruments. Background technique [0002] At present, in the clinical practice of otolaryngology, head mirrors and traditional classic nose and throat endoscopes are basically still used for inspection. [0003] However, the head mirror has the following deficiencies: 1. The viewing angle is limited; 2. The lesion cannot be viewed at close range; 3. The observed things cannot be digitized. [0004] The traditional classic nose and throat endoscope also has the following deficiencies: [0005] 1. Due to the huge image display system, it can only be used in the endoscopic examination room and operating room of the hospital. It has no conditions for use in the outpatient clinic and is not convenient to move. Therefore, the outpatient doctor can only ask the patient to have an examination in the endoscopic room. [0006] 2. Traditional rhinolaryngoscopes must be disinfected under...

AI Technical Summary

Problems solved by technology

[0003] But the lens has the following disadvantages: 1. The viewing angle is limited; 2. It is impossible to watch the lesion at close range; 3. It cannot digitize the observed things

[0005] 1. Due to the huge image display system, it can only be used in the endoscopic examination room and operating room of the hospital. It has no conditions for use in the outpatient clinic and is not convenient to move. Therefore, the outpatient doctor can only ask the patient to have an examination in the endoscopic room.

[0006] 2. Traditional rhinolaryngoscopes must be sterilized by 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
