Hospital Hydrogen Peroxide Sterilization Technology

Hydrogen peroxide sterilization technology primarily utilizes the strong oxidizing properties of hydrogen peroxide vaporized by sterilization equipment to kill microorganisms. Hydrogen peroxide decomposes to produce free radicals that damage microbial cell membranes and enzyme systems, rendering them inactive and achieving sterilization. The dry fog characteristics and uniform volatilization of hydrogen peroxide solution sprayed by the equipment ensure even distribution of hydrogen peroxide throughout the space.

Hydrogen peroxide possesses strong oxidizing properties that act on microbial cell walls, altering their permeability, causing microbial swelling and deformation. It oxidizes sulfhydryl-containing enzymes, causing metabolic activation enzymes to lose function. After entering microbial cells, the OH radicals and reactive oxygen species produced by decomposition react with proteins and nucleic acids, damaging DNA, ultimately leading to microbial death.

Terminal disinfection refers to the complete disinfection of an epidemic focus after the source of infection is hospitalized, transferred, dies, or leaves the focus, or when the infection state is terminated. The purpose is to completely eliminate viable pathogens spread and left by the patient on various objects in the epidemic focus, rendering the focus harmless.

In hospital environments, terminal disinfection is particularly important, especially after patients transfer departments, are discharged, or pass away. Complete disinfection of the wards they occupied, medical instruments used, and surrounding environment is essential. Hydrogen peroxide sterilization technology, with its efficient and residue-free characteristics, becomes an ideal choice for terminal disinfection.
