Example Embodiment

[0029] Example 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 mixing tank, turn on the stirring at room temperature and stir for 30 minutes to obtain an inert substance solution.

[0031] Put 3.5kg of 40% peroxyacetic acid and 17.3kg of 30% hydrogen peroxide into the above-mentioned inert material mixing tank. Stir at 25℃-35℃ for 2 hours to obtain the disinfectant mother liquor. The mother liquor is passed through three stages. Filtration using microporous membrane (the pore size of the filter membrane is 1.2μm-0.45μm-0.22μm, and the order of the pore size of the flow through the membrane is from large to small) and then the final product is filled.

Example Embodiment

[0032] Example 2

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

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

Example Embodiment

[0035] Example 3

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

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

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...
