Embodiment 1

[0040] Add 0.2 g of fatty alcohol polyoxyethylene ether and 0.2 g of nonylphenol polyoxyethylene ether into 96 g of water, stir to dissolve; add 0.02 g of alkaline protease, 0.02 g of lipase, 0.01 g of cellulase, and 0.01 g of amylase , while controlling the solution temperature below 30°C. After stirring and dissolving evenly, immediately add 0.5 g of glycerin, 0.3 g of propylene glycol, and 0.05 g of ethylene glycol and stir to dissolve; 3 g of dipropylene glycol methyl ether acetate and 0.5 g of p-chloro-m-xylenol are pre-dissolved in appropriate amount of purified water respectively. Then add and dissolve while stirring to obtain the pre-cleaning moisturizing agent.

Embodiment 2

[0042] Add 0.5 g of fatty alcohol polyoxyethylene ether and 0.5 g of nonylphenol polyoxyethylene ether into 94 g of water, stir to dissolve; add 0.1 g of alkaline protease, 0.1 g of lipase, 0.05 g of cellulase, and 0.05 g of amylase , while controlling the solution temperature below 30°C. After stirring and dissolving evenly, immediately add 1.3 grams of glycerin, 0.9 grams of propylene glycol, and 0.2 grams of ethylene glycol and stir to dissolve; 4 grams of dipropylene glycol methyl ether acetate and 0.75 grams of p-chloro-m-xylenol are pre-dissolved in appropriate amount of purified water respectively. Then add and dissolve while stirring to obtain the pre-cleaning moisturizing agent.

Embodiment 3

[0044] Add 1.0 g of fatty alcohol polyoxyethylene ether and 1.0 g of nonylphenol polyoxyethylene ether into 90 g of water, stir to dissolve; add 0.2 g of alkaline protease, 0.2 g of lipase, 0.1 g of cellulase, and 0.1 g of amylase , while controlling the solution temperature below 30°C. After stirring and dissolving evenly, immediately add 2.0 grams of glycerin, 1.5 grams of propylene glycol, and 0.4 grams of ethylene glycol and stir to dissolve; 5 grams of dipropylene glycol methyl ether acetate and 1.5 grams of p-chloro-m-xylenol are pre-dissolved in appropriate amount of purified water respectively. Then add and dissolve while stirring to obtain the pre-cleaning moisturizing agent.

[0045] The pre-cleaning and moisturizing agents of the above examples were continuously soaked for 14 days on stainless steel sheets, carbon steel sheets, copper sheets, and aluminum sheets, and no corrosion was found. Surgical forceps were used to soak starch solution, protein solution, and f...

Abstract

The invention relates to a pre-cleaning and moisturizing agent suitable for medical apparatuses, and preparation method thereof. The invention is characterized in that the pre-cleaning and moisturizing agent for the medical apparatuses is composed of a surfactant, a corrosion inhibitor, a humectant, protease, lipase, starch powder, cellulase, an osmotic agent and an enzyme stabilizer. The pre-cleaning and moisturizing agent has no irritating odor, is safe, low in toxicity and corrosion, free of chemical residuals, stable in performance and convenient to use, can be used for pre-cleaning and moisturizing surgical instruments, microsurgical instruments, flexible endoscopes, dental instruments, minimally invasive surgical instruments, rigid endoscopes and high frequency instruments and the like which are prepared from stainless steel, alloy of the stainless steel, copper, rubber and other materials.

Description

technical field [0001] The invention relates to cleaning and moisturizing of medical devices, in particular to a moisturizing agent suitable for medical devices and a preparation method thereof. Background technique [0002] In recent years, with the development of the national economy and the improvement of medical and health standards, all large and medium-sized hospitals in China have adopted centralized cleaning and sterilization of medical devices. Biological enzymes are being used more and more widely, especially in the "Operational Specifications for Endoscope Cleaning and Disinfection Technology" issued by the Ministry of Health, which clearly states that the cleaning and disinfection procedures of endoscopes are water washing→enzyme washing→cleaning→sterilization. One of the important links is It's an enzyme wash. In Europe, the "Correct Handling of Instrument Cleaning and Disinfection" issued by the Instrument Cleaning and Disinfection Expert Working Group stipula...
