Problems solved by technology

[0007] As we all know, lumen-type medical devices used for medical diagnosis or liquid medium delivery have a narrow lumen, which will be contaminated with blood, mucous membrane tissue or oil and other dirt during use. If the cleaning is not thorough enough, it will lead to serious bacteria breeding or pollution Corrosion disadvantages, thus threatening people's health, reducing the service life of equipment or affecting the accuracy of diagnosis or treatment results
[0008] However, these methods in the above-mentioned prior art are not suitable for cleaning and disinfection of lumen instruments, and it is difficult to completely decompose and remove these biological residues or oil stains in a short time by using conventional detergents (such as chemical detergents) and The cleaning effect is not good, but biological enzymes such as protease, amylase, lipase, etc. can decompose various biological pollutants or oil stains through chemical reactions, so as to effectively remove them

Abstract

The invention provides a method for cleaning and sterilizing instruments, especially pipe cavity type instruments. According to the method, multi-enzyme cleaning fluid is used, and an excellent cleaning effect can be achieved through effective multi-step cleaning. The multi-enzyme cleaning fluid comprises a surface active agent, cellulose, amylase, protease, lipase, additional enzymes, triethylamine, sodium alga acid, butylparaben, sodium tetraborate, ethanol, polyethylene glycol, auxiliaries and water. An excellent synergistic effect is achieved through proper selection of components and proportions of the components of the multi-enzyme cleaning fluid.

Description

technical field [0001] The invention relates to a method for cleaning and disinfecting instruments, in particular to a method for cleaning and disinfecting lumen instruments, and belongs to the field of cleaning and disinfecting precision instruments or medical instruments. Background technique [0002] Mechanical parts, precision components, material carrying devices and precision medical glass instruments are mainly made of metal materials or special glass, and these instruments will have varying degrees of wear and pollution during use. Effective cleaning and maintenance can prolong the service life of instruments and avoid material loss, thereby effectively reducing the frequency of replacement. Therefore, the development of cleaning methods for metal instruments or precision medical glass instruments has become a hot spot in the fields of chemical industry, electronics, and medicine. .
