Professional Disinfection Solution - Ensuring Safe Medical Environments, Preventing Healthcare-Associated Infections
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.
In the market, hydrogen peroxide sterilization is mainly used for space sterilization and surface sterilization, featuring efficient, broad-spectrum bactericidal capabilities that can eliminate various microorganisms including bacteria, viruses, and fungi.
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.
Hydrogen peroxide sterilization technology has wide application scenarios in hospitals, primarily including the following areas:
Used for terminal disinfection to ensure patient environmental safety and prevent cross-infection
Comprehensive disinfection of interior space after patient transport to prevent pathogen transmission
Ensures sterile laboratory environments, preventing sample contamination
Regular disinfection of high-risk areas to reduce infection risks
Safe disinfection of precision equipment environments without damaging sensitive equipment
Hydrogen peroxide is also suitable for terminal sterilization of heat- and moisture-sensitive precision instruments. Medical institution disinfection guidelines indicate that hydrogen peroxide sterilization can be used as a terminal disinfection method.
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.
To effectively maximize hydrogen peroxide sterilization results, the sterilization space should be relatively dry, with optimal temperature: 18~26℃, humidity: 40~60% [6](@ref).
| Parameter | Ideal Range | Explanation |
|---|---|---|
| Temperature | 18-26℃ | High temperatures accelerate hydrogen peroxide decomposition; low temperatures affect sterilization efficacy |
| Relative Humidity | 40-60% | High humidity causes premature hydrogen peroxide decomposition; low humidity affects diffusion |
| Hydrogen Peroxide Concentration | 3-8% | Hospital common concentration is 3%, balancing efficacy and safety |
| Exposure Time | Determined by space size | Typically 30-90 minutes, ensuring sufficient contact time |
