Description

High-efficiency multi-enzyme cleaning agent for medical equipment and preparation method thereof

technical field

The invention belongs to the technical field of special cleaning agents, and in particular relates to a high-efficiency multi-enzyme cleaning agent for medical instruments that can improve cleaning quality and efficiency and a preparation method.

Background technique

A variety of surgical and human examination tools in the hospital are reusable instruments. After use, the surface of such instruments will be contaminated with organic pollutants such as blood, grease, tissue fluid, and body fluids. Traditional chemical cleaning agents cannot completely clean them. . Due to the complex components of the residual organic pollutants, biofilms can be accumulated on the surface of the device, which will lead to serious pollution and corrosion or the growth of bacteria, which will not only reduce the service life of the device, but also pose a threat to people's health. At present, it has been found that some biological enzymes can react with specific organic substances, thereby decomposing pollutants, so there are many kinds of biological enzyme cleaning agents, and each cleaning agent chooses protease, cellulase, fat One or more of biological enzymes such as enzyme, amylase and lysozyme. However, in the actual operation of the medical industry, it is difficult to ensure timely cleaning of the used instruments. Long-term storage causes organic matter to dry up and adhere to the instruments. Even with existing biological enzyme cleaning agents, it is difficult to clean. To ensure that organic pollutants are thoroughly cleaned, there are great potential safety hazards.

Contents of the invention

The present invention aims to solve the above-mentioned technical problems existing in the prior art, and provides a high-efficiency multi-enzyme cleaning agent for medical instruments and a preparation method that can improve cleaning quality and efficiency.

The technical solution of the present invention is: a high-efficiency multi-enzyme cleaning agent for medical equipment, which is characterized in that the raw materials used and the mass percentage are as follows: isomeric tridecyl alcohol ether oxide 0.5-5%, propylene glycol 5-10%, potassium lactate 1 ~20%, biological enzyme 2%, cleaning aid 0.1~5%, the balance of deionized water; the biological enzyme is a mixture of protease, lipase, cellulase, amylase and lysozyme; the cleaning aid For ferric chloride, sodium chlorate or potassium permanganate.

A preparation method of the above-mentioned high-efficiency multi-enzyme cleaning agent for medical instruments is carried out according to the following steps:

a. Dissolve isotridecyl alcohol ether oxide, propylene glycol, potassium lactate and cleaning aid in deionized water, stir evenly, and cool for later use;

b. Add lipase, cellulase, amylase, lysozyme and protease to the liquid prepared in step a in sequence, and stir evenly.

The invention has wide source of raw materials and simple preparation method. The components interact with each other. Compared with the existing medical multi-enzyme cleaning agent, the present invention has the advantage that it is easier to adsorb on the surface of the device, thereby acting as a "wedge", so that organic pollutants, even dried organic matter, are removed from the device. Surface peeling; it can oxidize organic pollutants, denature or break large molecular weight organic matter into small molecular weight organic matter, which is beneficial to the decomposition of organic matter by biological enzymes, and can improve cleaning quality and efficiency.

Detailed ways

Example 1:

The raw materials and mass percentages used are as follows: isotridecyl alcohol ether oxide 0.5%, propylene glycol 10%, potassium lactate 20%, protease 0.5%, lipase 0.5%, cellulase 0.3%, amylase 0.4%, lysozyme 0.3% %, 0.1% potassium permanganate and the balance of deionized water.
