Abstract

The invention relates to a multifunctional disinfectant for a haemodialysis machine, which is prepared by using peroxyacetic acid and hydrogen peroxide as the main materials, adding stabilizer salicylic acid, EDTA disodium salt and 8-hydroxyquinoline in the raw materials and blending the mixture. The multifunction disinfectant of the haemodialysis machine comprises the following components in percentage by weight: 4.0 to 6.0 percent of peroxyacetic acid, 18.0 to 22.0 percent of hydrogen peroxide, 0.3 to 1.5 percent of salicylic acid, 0.3 to 1.0 percent of EDTA disodium salt, 0.3 to 1.0 percent of 8-hydroxyquinoline and the balance of water. The multifunction disinfectant of the haemodialysis machine has the advantages of rational formulation, stable performance, convenient use, relatively strong capabilities of disinfection of removal of organics, safety, non-toxic and no residual. The multifunction disinfectant is mainly used for washing and disinfecting instruments such as the haemodialysis machine, the hollow fiber dialyser and the like.

Description

technical field [0001] The invention relates to a disinfectant, in particular to an improved multifunctional disinfectant for a hemodialysis machine. Background technique [0002] We know that hemodialysis machine is a kind of therapeutic equipment. In order to use it safely, the machine needs to be disinfected after each use. Commonly used disinfectants in the field of food production and processing include sodium hypochlorite, sodium dichloroisocyanurate, chlorine dioxide, peracetic acid, hydrogen peroxide (hydrogen peroxide), etc. Sodium hypochlorite, sodium dichloroisocyanurate, and chlorine dioxide are cheap, but they can react with organic matter to form carcinogenic halogenated hydrocarbons, which are toxic and odorous, and are not suitable for disinfection of medical devices such as hemodialysis machines. Peracetic acid or hydrogen peroxide has a fast sterilization speed, is non-toxic and has no residue, and is suitable for the disinfection of medical devices such a...
