Embodiment 1

[0010] Embodiment 1: Prepare the components of the disinfectant solution, polyhexamethylene guanidine 0.001-5.0%, citric acid 10-50%, lactic acid 20.0%-40%, malic acid 70%-10%, and the balance is deionized water. Add polyhexamethyleneguanidine, citric acid, lactic acid, and malic acid to an appropriate amount of deionized water in stages, stir for 15 minutes during the addition, and stand still for 1 hour to fully dissolve and stir evenly to obtain medical dialysis Machine and water treatment with citric acid decalcification disinfectant. The disinfectant has reasonable formula, stable performance, convenient use, good bactericidal effect, safety and reliability, and no potential risk. It is especially suitable for the cleaning and disinfection of dialysis machines and water treatment in hospital dialysis rooms, as well as the removal of organic matter.

Embodiment 2

[0011] Example 2: Prepare the components of the disinfectant solution, including 2% polyhexamethyleneguanidine, 10% citric acid, 20.0% lactic acid, 70% malic acid, and the balance is deionized water. Add polyhexamethylene guanidine, citric acid, lactic acid, and malic acid to an appropriate amount of deionized water in stages, stir for 15 minutes during the addition, and stand still for 12 hours to fully dissolve and stir evenly to obtain medical dialysis Machine and water treatment with citric acid decalcification disinfectant. The disinfectant has reasonable formula, stable performance, convenient use, good bactericidal effect, safety and reliability, and no potential risk. It is especially suitable for the cleaning and disinfection of dialysis machines and water treatment in hospital dialysis rooms, as well as the removal of organic matter.

[0012] Impurities in the hemodialysis machine pipeline that affect the dialysis effect mainly include calcium carbonate, magnesium c...

Abstract

The invention belongs to the technical field of disinfectants, in particular to a citric acid decalcified disinfectant applied to dialysis machinery and water treatment and a preparation method of the citric acid decalcified disinfectant. The citric acid decalcified disinfectant comprises the following raw materials: 0.001 to 5.0 percent of poly-hexamethylene guanidine, 10 to 50 percent of citric acid, 20.0 to 40 percent of lactic acid, 10 to 30 percent of malic acid and the balance of deionized water, wherein citric acid, poly-hexamethylene guanidine, lactic acid and malic acid serve as main raw materials; poly-hexamethylene guanidine has a fast powerful bactericidal effect, is free from organic materials, pH value and temperature, and is colorless, smell-less, non-combustible, non-explosible, safe, environment-friendly, and convenient to use. The disinfectant is especially used for cleaning and disinfecting various hemodialysis machineries, and is high in disinfecting and organic material removing capabilities.

Description

technical field [0001] The invention belongs to the technical field of disinfectant, in particular to a citric acid decalcifying disinfectant used in dialysis machines and water treatment and a preparation method thereof. Background technique [0002] We know that the infection problem of hospital dialysis room and dialysis machine is becoming more and more prominent, which has become an urgent problem to be solved by the hospital. The disinfectants used in foreign dialysis machines are mainly Lunalin; Hong Kong Fresenius Blood Care Group’s peracetic acid disinfectant; Oak 2000 peroxide compound disinfectant. Domestically, it is mainly Ximolin brand dialyzer disinfectant. The currently internationally recognized standards for ideal disinfectants are: broad-spectrum sterilization, fast action; stable performance, easy storage and transportation; non-toxic, tasteless, non-irritating, non-carcinogenic, soluble in water, non-coloring, easy to remove, non-flammable Explosive, s...
