Embodiment 1

[0030] First, take 0.01 kg of sodium pyrophosphate, 19.0 kg of glacial acetic acid, and 61.2 kg of reverse osmosis water in a liquid mixing tank, start stirring at room temperature and stir for 30 minutes to obtain an inert substance solution.

[0031] Put 3.5kg of 40% peracetic acid and 17.3kg of 30% hydrogen peroxide into the above-mentioned inert substance liquid mixing tank and stir at 25°C-35°C for 2 hours to obtain a disinfectant mother liquor, which is passed through three stages Type microporous membrane filtration (the pore size of the filter membrane is 1.2μm-0.45μm-0.22μm, and the order of flow through the filter membrane pore size is from large to small) and then filled to obtain the final product.

Embodiment 2

[0033] Take 0.02kg of sodium pyrophosphate, 20.0kg of glacial acetic acid, and 56.0kg of reverse osmosis water in a liquid mixing tank, start stirring at room temperature and stir for 30 minutes to obtain an inert substance solution.

[0034] Put 4.0kg of 40% peracetic acid and 20.0kg of 30% hydrogen peroxide into the above-mentioned liquid mixing tank and stir at 25°C-35°C for 2.5 hours to obtain a disinfectant mother liquor. Pore ​​filter membrane filtration (the pore size of the filter membrane is 1.2μm-0.45μm-0.22μm, and the order of flow through the filter membrane pore size is from large to small) and then filled to obtain the final product.

Embodiment 3

[0036] Take 0.03kg of sodium pyrophosphate, 22.0kg of glacial acetic acid, and 56.0kg of reverse osmosis water in a liquid mixing tank, start stirring at room temperature and stir for 30 minutes to obtain an inert substance solution.

[0037] Put 4.6kg of 40% peracetic acid and 20.0kg of 30% hydrogen peroxide into the above-mentioned liquid mixing tank and stir at 25°C-35°C for 2 hours to obtain a disinfectant mother liquor. Pore ​​filter membrane filtration (the pore size of the filter membrane is 1.2μm-0.45μm-0.22μm, and the order of flow through the filter membrane pore size is from large to small) and then filled to obtain the final product.

Abstract

The invention discloses a solution for sterilizing and cleaning a hemodialysis machine and a preparation method of the solution. The solution is prepared from peroxyacetic acid, hydrogen peroxide, water, glacial acetic acid and sodium pyrophosphate. The preparation method comprises the following steps: putting water, glacial acetic acid and sodium pyrophosphate into a solution preparing tank to prepare an inert solution; stirring for dissolving for 30 minutes; adding peroxyacetic acid and hydrogen peroxide in the solution preparing tank to obtain a mixed solution; and filtering the mixed solution through a three-section type membrane filter and performing filling to obtain the product. The product has stable performance and a validity period lasting for two years long, and is capable of effectively exterminating intestinal tract pathogenic bacteria, pyogenic cocci, pathogenic yeasts and bacterial spores.

Description

technical field [0001] The invention relates to a solution for disinfection and cleaning, in particular to a solution for disinfection and cleaning of a hemodialysis machine and a preparation method thereof. Background technique [0002] Hemodialysis machine disinfectant is an important disinfection product in the daily use and maintenance of hemodialysis machines. Effective cleaning and disinfection of the counting lines, cuvettes and other parts of the hemodialysis machine can stabilize the instrument and prolong its life. [0003] Jinbao AK100 hemodialysis machine is widely used in China, and the demand for cleaning fluid is large. However, most of the cleaning fluid used is imported CA CLEAN I, which is expensive and completely dependent on imports. A cleaning solution is disclosed in US4745071, but the cleaning solution has complex components and high cost. At present, some products of the same kind on the market have relatively high concentrations, and must be manuall...
