Problems solved by technology

[0003] The literature shows that the neutral multi-enzyme cleaners and alkaline multi-enzyme cleaners commonly used in medical institutions have a good cleaning effect on common surgical instrument pollutants such as protein and fat, but the removal effect on biofilm is poor
The strong alkaline solution has a good effect on the removal of biofilm, but it has a great aging effect and corrosion on the material of the endoscope.

Embodiment 1

[0029]

[0030] The preparation method is as follows:

[0031] (1) Add distilled water into the reaction vessel, turn on the agitator, then add sodium tripolyphosphate, sodium citrate, TTA, and sorbic acid in sequence, and keep stirring until all are dissolved to obtain a liquid; After stirring for 30 minutes, the next raw material can be added;

[0032] (2) The liquid obtained in step (1) is filtered using a double-layer 400-mesh filter cloth to obtain a solution;

[0033] (3) Add 1.2-propylene glycol, Tween 20, RQ-129E to the solution obtained in step (2) successively, and keep stirring for 60 min;

[0034] (4) Add Mirataine ASC into the reaction vessel and keep stirring for 30 minutes to obtain the product.

Abstract

The invention belongs to the technical field of products for medical cleaning, and in particular relates to a bio-film remover for medical endoscopes and a preparation method thereof. The bio-film remover for medical endoscopes is prepared from the following materials: sodium tripolyphosphate, sodium citrate, 1.2-propylene glycol, Tween-20, sorbic acid, RQ-129E, Mirataine ASC, TTA and distilled water. The bio-film remover can rapidly and thoroughly remove bio-film; the amount of foam is small, and the bio-film remover is suitable for manual washing and mechanical washing; the bio-film remover can be repetitively used, and has a persistent bio-film removing effect; and the bio-film remover cannot corrode endoscope materials, and prolongs the service lives of endoscopes.

Description

technical field [0001] The invention belongs to the technical field of medical cleaning supplies, and in particular relates to a biofilm remover for medical endoscopes and a preparation method thereof. Background technique [0002] In the medical field, endoscopic biofilm is one of the important causes of nosocomial cross-infection. Bacterial biofilm (Bacterial bio-film, BF) is composed of extracellular polymer matrix (extracellular polymeric substance, EPS) secreted by bacteria and bacteria themselves, and irreversibly adheres to non-biological or biological surfaces, which protects bacteria Protects against environmental influences and increases bacterial resistance to fungicides. The resistance of bacteria in biofilm is 1000 times stronger than that of planktonic bacteria. Studies have found that biofilm formation can significantly reduce the effectiveness of disinfectants. As an invasive and minimally invasive diagnosis and treatment tool, endoscope has been widely us...
