In a real sense, the three-barrel disinfection method was the most widely used at first, but later it was found that this ancient and imprecise method could not achieve the effect of thoroughly cleaning and soaking the endoscope. So this method was forcibly abolished. So there are three cans, four cans or even five cans disinfection methods, but these are only the improvement and extension of the three-barrel disinfection method. Although there has been great progress, it is not perfect. Until now, the integrated disinfection of endoscope is still widely used.

With good equipment, there must be a good disinfectant. Glutaraldehyde is the most commonly used disinfectant, which has good disinfection effect and does not corrode the scope. However, it is necessary to check the concentration at any time during use, and remember that the endoscope must be scrubbed with washing liquid before soaking and disinfection, otherwise the tissues and secretions attached to the surface and cavity of the endoscope will solidify into crystals due to contact with acetaldehyde complex, which will directly affect the performance and service life of the mirror. One more thing, if crystals have already formed, be careful not to remove them.

In addition, the endoscope is thoroughly cleaned and disinfected. Before storage, make sure that the surface of the endoscope and all the pipes are completely dry, because the residual water inside and outside the endoscope will help the bacteria in the air to multiply and cause pollution.
