Embodiment 1

[0019] The preparation method of Example 1 is as follows: firstly add distilled water into the container, then add APG, bactericide and sodium citrate therein, mix uniformly, then add each compound enzyme, stir uniformly, and filter to prepare. When feeding, one raw material is dissolved and then another is added, the stirring speed is 180±5r / min, the dissolution temperature is 45°C, and a 200-mesh filter is used to filter twice.

Abstract

The invention belongs to the technical field of medical detergents, and relates to a multienzyme cleaning solution suitable for machine-washable medical devices and a preparation method thereof. The multienzyme cleaning solution comprises the following ingredients by mass percent: 77-89% of water, 2-4% of protease, 1-3% of lipase, 1-2% of amylase or / and 0.5-2% of cellulose, 1-3% of low-foam high-efficiency surfactant, 0.5-1% of bactericide and 2-5% of chelating agent. As enzymes such as neutral protease, lipase, alpha-amylase and the like are composited and the function is mild, the multienzyme cleaning solution can be used for cleaning equipment and hand washing operation, is capable of rapidly removing the organic pollutants such as blood, fester and the like on medical devices, and has the advantages that no corrosion is caused, the foam is low, the biodegradation is easy, no residues exist, the cleaning effect is good and the like.

Description

technical field [0001] The invention belongs to the technical field of medical detergents, and relates to a multi-enzyme cleaning agent suitable for machine-washing medical instruments and a preparation method thereof. Suitable for automatic machine cleaning. Background technique [0002] The purpose of cleaning is to remove the dirt from the surface of the object, dissolve it in the detergent, and completely separate it from the reusable device by rinsing. Cleaning is a complicated process, and the choice of cleaning agent should also meet various factors. The cleaning agent should have a strong decontamination ability, have good compatibility with the cleaned equipment and washing machines, and be easy to rinse to reduce residues. [0003] Biofilms are a form of bacterial presence that collectively resist external environmental challenges in a sticky matrix they secrete. The accumulation of biofilm caused by repeated use of medical devices is difficult to completely rem...
