Disposable sleeve used together with ear examination endoscope and throat examination endoscope

Abstract

The invention relates to a disposable sleeve used together with an ear examination endoscope, which comprises a rear cover, a front cover, an external sleeve, an internal sleeve and a light transmission optical fibre, wherein the front end of the light transmission optical fibre is level with the front end of the external sleeve and the rear end passes through a cavity between the rear end and the front end and is opened at the end face of the rear end, the rear end of the light transmission optical fiber is butted with an LED, and the rear cover can be sleeved on a cage nut of the endoscope.The disposable sleeve used together with a nose and throat examination endoscope also comprises a hot gas channel comprising a guide hole, a guide cavity, a gap between the external sleeve and the internal sleeve and an opening on the guide cover. The invention is used for the ear examination endoscope and the nose and throat examination endoscope, solves the problems of poor sterilization timeliness and easy fogging of the sterilization, and has the advantages of free sterilization, no fogging of exposed optical parts and no limit of observation angles.

Description

technical field [0001] The invention relates to medical instruments, in particular to ENT medical instruments. Background technique [0002] At present, head mirrors, otoscopes and ENT endoscopes are basically still used in the clinical practice of ENT. [0003] However, head mirrors and otoscopes have the following deficiencies: 1. The viewing angle is limited; 2. The lesions cannot be viewed at close range; 3. The observed things cannot be digitized. [0004] ENT endoscopy also has the following disadvantages: [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 otolaryngoscopes must be sterilized under high temperature and high pressure or soaking b...

AI Technical Summary

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
