Endoscope cleaning agent containing multiple enzymes capable of effectively removing biological membranes and preparation method of endoscope cleaning agent

Abstract

The invention relates to an endoscope cleaning agent containing multiple enzymes capable of effectively removing biological membranes and a preparation method of the endoscope cleaning agent. The endoscope cleaning agent comprises the following raw materials in parts by weight: 5-15 parts of linear alkylbenzene sulfonates, 1-10 parts of ethoxylated fatty alcohols, 0.1-5 parts of triethanolamine, 0.5-5 parts of ethylenediaminetetraacetic acid, 0.5-2 parts of fatty acids, 0.1-1 patr of phosphonate, 1-10 parts of propylene glycol, 1-10 parts of 1,2-benzisothiazolin-3-one, 0.5-10 parts of protease, 0.5-10 parts of amylase, 0.5-10 parts of cellulose, 0.5-10 parts of lipase, 0.10-0.5 part of a preservative and 1.5-88.7 parts of softened water, wherein the added sodium hydroxide is capable of reaching the pH value 8-10 of the solution. The endoscope cleaning agent disclosed by the invention is excellent in biological membrane removal effect, non-corrosive to endoscopes and appliances, obvious in bacteria-eliminating efficacy and high in cleaning quality, and the preparation method is simple and feasible.

Description

technical field [0001] The invention relates to a medical endoscope cleaning agent, in particular to an endoscope cleaning agent containing multiple enzymes that can effectively remove biofilm and a preparation method thereof. Background technique [0002] Endoscope (referred to as endoscope) is a commonly used medical device, which consists of a bendable part, a light source and a set of lenses. When in use, the endoscope is introduced into the organ to be inspected, and the changes in the relevant parts can be directly observed. According to different diagnosis and treatment parts, endoscopy can be divided into gastroscopy, colonoscopy, bronchoscopy, laryngoscopy, nasal endoscopy, cystoscopy, laparoscopy and so on. [0003] A survey on the status quo of endoscopic disinfection in hospitals in Urumqi, Xinjiang, published in the 4th issue of "Chinese Journal of Disinfection" in 2009, showed that the average pass rate of endoscopic disinfection in some medical institutions i...

Problems solved by technology

[0004] The body of the endoscope is complex, there are many lumens and sinuses, the diameter of the biopsy / suction pipe is Ø3mm to Ø5mm or even smaller, and the diameter of the water injection / air injection pipe is 1 / 15 of the biopsy / suction pipe, which makes the cleaning and disinfection of the endoscope There are very big difficulties; especially because of the special materials and fine structure, many parts are not resistant to high temperature, high pressure, and are afraid of corrosion, so they can only be disinfected at low temperature or soaked in disinfectant

[0005] The unevenness of the surface of the endoscope pipeline directly leads to the formation of bacterial biofilm. The biofilm on the surface of the endoscope will prevent the penetration of the disinfectant and wrap the microorganisms in it, resulting in the failure of disinfection.

[0006] At present, the cleaning effect of commonly used enzyme lotion is not ideal, and there is no product that is aimed at removing biofilm, which directly affects the anti-virus effect
