The hydrogen peroxide sterilizer on an ambulance is a scientific instrument used in the fields of basic and public health for the disinfection and sterilization of spaces and surfaces in biosafety laboratories. Disinfection refers to the use of physical or chemical methods to eliminate pathogens that remain in different media, in order to cut off transmission routes, prevent and control the spread of pathogens. Hydrogen peroxide sterilizers are widely used in various industries for disinfection and sterilization purposes.

The disinfection principle of hydrogen peroxide sterilizer is to diffuse the dry fog to the area to be disinfected to complete the spray process. When the average diameter of droplets is less than 10 microns, the sprayed mist can be referred to as "dry"; Small droplets will bounce off the wall without breaking or adhering, making the surface moist. The establishment of all conditions is to ensure that the sterilizing agent effectively diffuses into the area in the form of gasification. The characteristics of this form determine that they can spread to areas that are usually difficult to reach.

The spray from the hydrogen peroxide sterilizer is used to disinfect the ambulance carriage. The diameter of atomized hydrogen peroxide in the hydrogen peroxide sterilizer is 3 microns, which cannot be seen by the naked eye. It can spread to every corner through irregular movements. With the disinfection method of wiping with chlorine containing disinfectant, hydrogen peroxide spray disinfection is simple and can be completed in about 3 minutes by an ambulance, saving a lot of time. Because it does not form water droplets, there is no need to dry it after disinfection, saving a lot of manpower. The final decomposition products of hydrogen peroxide are oxygen and water, which have low corrosiveness to on-board equipment, minimal harm to passengers, and no pollution to the environment. After spraying is completed, the ambulance will be turned off for half an hour and can be reused.
