Description

An endoscope hose leak detection device

technical field

The utility model relates to the field of endoscope leak detection, in particular to an endoscope hose leak detection device.

Background technique

Electronic endoscopes are commonly used equipment for inspection, diagnosis and treatment. The structure of electronic endoscope is precise and the price is relatively expensive. However, due to the limitation of technology and conditions, the maintenance cost of electronic endoscope is also high. A lot of experience shows that many failures of electronic endoscopes are caused by incorrect operation, non-routine disinfection, and inadequate maintenance. Therefore, the correct operation and daily careful maintenance of electronic endoscopes are very important. During the use, cleaning, and disinfection of electronic endoscopes, the endoscope may be damaged due to the influence of external forces, resulting in endoscope skin or The inner tube is perforated. The electronic endoscope has precision electronic components, and the internal water vapor isolation is particularly important. Once the internal water seeps, it will not only easily cause rust and wear of the internal moving parts, but in severe cases, it will short-circuit and damage the precision electronic components such as CCD, resulting in high maintenance costs. Internal water seepage also presents a potential cross-contamination hazard for endoscopes. Therefore, only well-sealed electronic endoscopes can be soaked, cleaned and disinfected. The regular water leakage test is an important link to confirm the airtight effect of the electronic endoscope. Use a mechanical air pump and other devices to continuously supply air to the cavity to make the cavity pressure reach a certain value, and then place the endoscope in water as a whole to observe the endoscope. Check whether there are continuous bubbles coming out of the mirror, if there is, it is judged that the cavity is leaking, otherwise the leak test passes. The immersion leak detection method needs to place the endoscope in water as a whole, which is more complicated and time-consuming. Operation errors may cause water to enter the cavity, and the judgment result is too subjective. Air pressure leak detection will not cause endoscope leakage In case of water entry, there are few devices on the market that detect air pressure leaks.
