Endoscope for preventing liquid immersion

Abstract

The invention discloses an endoscope for preventing liquid immersion. The endoscope comprises a ventilation connector which can be communicated with an inner cavity of an endoscope body, and a waterproof air permeable membrane is arranged in the ventilation connector. Since the waterproof air permeable membrane is arranged in the ventilation connector, compared with a mechanical spring thimble structure, the endoscope has the advantages that the structure is simpler, no additional operation is required, the waterproof air permeable membrane can make the inner cavity of the endoscope body communicated with outside air, and external liquid and liquid droplets cannot pass through the waterproof air permeable membrane due to a surface tension effect of the waterproof air permeable membrane sothat the liquid can be effectively prevented from entering the inner cavity of the endoscope body, balance of air pressure inside and outside the endoscope can also be achieved, and the possibility ofmisoperation by people is reduced.

Description

Technical field [0001] The present invention relates to the technical field of endoscopes, in particular to a liquid-proof endoscope. Background technique [0002] Endoscope is by far the most convenient, direct and effective medical device for medical staff to observe the diseased tissue inside the human body. Through it, the lesions that cannot be displayed by X-ray can be seen. Its wide clinical application not only reduces the trauma of surgery , The greater the accuracy and safety of the operation. [0003] When medical staff use, clean or disinfect the endoscope, the liquid is easy to penetrate the inner cavity of the endoscope. After the endoscope enters the water, the key components are basically scrapped. Therefore, the inner cavity of the endoscope is often sealed from the outside world. In the process of disinfection and transportation, especially air transportation, due to the drastic changes in the external atmospheric pressure, the endoscope is easily damaged due to ...

AI Technical Summary

Problems solved by technology

[0003] When medical personnel use, clean or disinfect the endoscope, the liquid is easy to soak into the inner cavity of the endoscope, and the key components of the endoscope are basically scrapped after the water enters it. During disinfection and transportation, especially by air, the endoscope is easily damaged by the pressure difference between the inside and outside due to the drastic changes in the external atmospheric pressure. Type spring thimble structure, by covering a balance cap, the thimble is pushed away, and the internal and external air pressure is the same, so that the internal and external air pressure of the endoscope is balanced and at the same time prevents the endoscope from being immersed in liquid. Convenient, and very easy to operate mistakes, such as forgetting to remove the balance cap, which will cause the liquid to directly enter the inner cavity and damage the endoscope
