[0038] The preparation method of biological enzyme cleaning agent for medical instruments of the present invention specifically carries out according to the following steps:

[0039] step 1,

[0040] Weigh 10%-30% cellulase, 5%-40% neutral protease, 10%-30% fungal α-amylase, 5%-40% lipase, 10%-30% % xylanase, the sum of the mass percentages of the above components is 100%; respectively dissolve the weighed cellulase, neutral protease, fungal α-amylase, lipase and xylanase in distilled water for 24 hours Afterwards, get the upper solution and filter it with a Buchner funnel to obtain cellulase stock solution, neutral protease stock solution, fungal α-amylase stock solution, lipase stock solution and xylanase stock solution, then filter the cellulase stock solution, medium Protease stock solution, fungal α-amylase stock solution, lipase stock solution, and xylanase stock solution are mixed in sequence to obtain biological enzymes;

[0041] Step 2,

[0042] Take by weight 19% ...

Embodiment 1

[0047] Take by weighing 10% cellulase according to mass percentage, 35% neutral protease, 10% fungal α-amylase, 35% lipase, 10% xylanase, the cellulose that weighs is respectively Enzymes, neutral protease, fungal α-amylase, lipase and xylanase were dissolved in distilled water for 24 hours, and then the upper solution was filtered with a Buchner funnel to obtain cellulase stock solution, neutral protease stock solution, and fungal α-starch Enzyme stock solution, lipase stock solution and xylanase stock solution, and then the filtered cellulase stock solution, neutral protease stock solution, fungal α-amylase stock solution, lipase stock solution, and xylanase stock solution are mixed in sequence to obtain biological enzyme ; Take by weight 19% alkylphenol polyoxyethylene ether, 40% alkyl polyoxyethylene ether sodium sulfate, 40% fatty alcohol polyoxyethylene ether, and 1% biological enzyme; The polyoxyethylene ether was stirred at 75°C for 40 minutes, and then the weighed alk...

Embodiment 2

[0049] Take by weighing 30% cellulase according to mass percentage, 5% neutral protease, 30% fungal α-amylase, 5% lipase, 30% xylanase, the cellulose that takes by weighing Enzymes, neutral protease, fungal α-amylase, lipase and xylanase were dissolved in distilled water for 24 hours, and then the upper solution was filtered with a Buchner funnel to obtain cellulase stock solution, neutral protease stock solution, and fungal α-starch Enzyme stock solution, lipase stock solution and xylanase stock solution, and then the filtered cellulase stock solution, neutral protease stock solution, fungal α-amylase stock solution, lipase stock solution, and xylanase stock solution are mixed in sequence to obtain biological enzyme ; Take by weight 19% alkylphenol polyoxyethylene ether, 40% alkyl polyoxyethylene ether sodium sulfate, 40% fatty alcohol polyoxyethylene ether, and 1% biological enzyme; Stir the polyoxyethylene ether at 80°C for 30 minutes, then fully mix the weighed alkylphenol...

Abstract

The invention discloses a bio-enzyme cleaning agent for medical apparatuses, which comprises the following components in percentage by weight: 19 percent of alkylphenol ethoxylate, 40 percent of alkyl polyoxyethylene ether sodium sulfate, 40 percent of fatty alcohol-polyoxyethylene ether and 1 percent of bio-enzyme, wherein the bio-enzyme comprises the following components in percentage by weight: 10-30 percent of cellulase, 5-40 percent of neutral protease, 10-30 percent of fungus alpha-amylase, 5-40 percent of lipase and 10-30 percent of xylanase. The invention also discloses a preparation method of the bio-enzyme cleaning agent, comprising the following steps of: respectively weighing the required five enzymes, adding distilled water for dissolving, taking and filtering upper solutions, and sequentially mixing the upper solutions to obtain the bio-enzyme; adding water to mix the alkylphenol ethoxylates, the alkyl polyoxyethylene ether sodium sulfate and the fatty alcohol-polyoxyethylene ether to obtain a solution; and then adding the bio-enzyme to the solution and mixing to obtain the bio-enzyme cleaning agent. The cleaning agent can be used for quickly removing fibers, bloodstains, protein, starch, sugar and fat on medical apparatuses and has the advantages of good decomposition effect and stable cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of cleaning products, and relates to a biological enzyme cleaning agent for medical equipment, and also relates to a preparation method of the cleaning agent. Background technique [0002] For a long time, cleaning agents use chemically synthesized surfactants, which not only cause environmental pollution, but also have an impact on the environment due to their chemical residues. If medical equipment is not cleaned cleanly, it will cause infection and affect the health of patients and medical staff. On June 15, 2006, the Ministerial Meeting of the Ministry of Health discussed and passed the "Management Measures for Hospital Infection", which advocated the use of biological enzyme cleaners as disinfectants for medical devices. [0003] There are many precious and precise medical instruments with small hollow cavities. When the instrument enters the human body, it is contaminated with mucus secretions, blood,...
