Abstract

The invention provides a bactericide for medical instruments. The bactericide for the medical instruments is prepared from the following components, by weight, 1.5%-3% of a surfactant, 0.5%-1% of glutaraldehyde, 10%-15% of citric acid, 30%-40% of hydrogen peroxide, 5%-10% of a rust remover, 1%-2% of a fog inhibitor, 3%-4% of lysozyme, 1%-2% of auxiliaries, and the balance being distilled water. The cationic surface active agent is one of chlorhexidine or benzalkonium bromide; the cationic surfactant and water form a solution; the ratio of the cationic surfactant to the water is 1: 1. 50-55; the coco fatty acid diethanolamide and the water form a solution, the ratio of the coco fatty acid diethanolamide to the water is 1: 55-60; the surfactant comprises a mixture of a cationic surfactant and the coco fatty acid diethanolamide, and the mixing ratio of the cationic surfactant to the coco fatty acid diethanolamide is 1: 0.5-0.8.

Description

technical field [0001] The invention relates to the field of bactericide technology, in particular to a bactericide for medical equipment. Background technique [0002] Bacteria form spores in adverse environments, and spores have strong resistance. Therefore, surgical instruments in hospitals must be sterilized at high temperature before use. The purpose is to kill bacterial spores with strong resistance. Only by completely destroying the spore structure of bacteria , in order to achieve the purpose of disinfection. Bacteria can form spores to survive the adverse environment when they encounter an adverse environment. Under certain conditions, some bacteria (mostly bacilli) have thickened cell walls and highly concentrated and dehydrated cytoplasm to form a spherical or oval dormant body with strong stress resistance. The most important feature of spores is strong resistance to high temperature, ultraviolet rays, dryness, ionizing radiation and many toxic chemicals. When e...
