(a) What is terminal disinfection
Terminal disinfection refers to the last thorough disinfection service after the source of infection (cases and asymptomatic infected people) has left the premises, to ensure that the premises being disinfected and the various items in it are free of pathogens. Final disinfection can be used to prevent infectious disinfection and the occurrence of infectious organisms disinfection services, such as hospital wards, CT rooms, operating room infections, aseptic biological laboratories, disinfection of pharmaceutical plant rooms. Recent norovirus, influenza A frequent epidemic in schools and kindergartens, due to the denseness of the population, pathogenic microorganisms in the environmental surface transmission to a certain extent increased the potential for cross-infection of the population. In response to the public **** place of concentrated fever epidemic risk, the final disinfection is very important and necessary.
(ii) the method of final disinfection
Disinfection is an effective measure to cut off the spread of the virus. No matter what kind of germs infection, its main way of transmission is "contact transmission", therefore, the contaminated environmental surfaces become an important source of infection for susceptible people to get infectious pathogens. Manual spraying and wiping disinfection services can only reduce the number of colonies on the surface of the object by 25% to 30%, and ultraviolet light is only effective on the surface of the object and the place where it can be irradiated. Not only the surface of the environment is seriously contaminated by bacteria and viruses, but also these bacteria and viruses can survive for a long time on the surface of the inanimate environment, such as: methicillin-resistant Staphylococcus aureus, VRE and Acinetobacter baumannii can survive for weeks or even months. Among the current environmental disinfection service technologies, Shanghai FANTON bio-vaporized hydrogen peroxide disinfection service technology is recognized as the ideal sterilization method for biological purification in pharmaceutical, biological and healthcare industries, which can achieve a killing rate of 6log for the bio-indicator, thermophilic Bacillus subtilis.
(C) Vaporized hydrogen peroxide final disinfection
Hydrogen peroxide (H2O2) is a naturally-occurring chemical substance, which has a good killing effect on many kinds of microorganisms, such as Escherichia coli, Salmonella, Staphylococcus aureus, Staphylococcus albicans, Hepatitis A and B viruses, and fungi. The 35% hydrogen peroxide disinfectant solution of Shanghai Fantong Biological is vaporized into gaseous hydrogen peroxide by high temperature flash vaporization and diffused into the air. Hydrogen peroxide molecules will release strong oxidizing free radicals, which can rapidly penetrate the cell membrane of bacteria and have irreversible reaction with it to kill the bacteria, and it can also react with the viral envelope to kill the virus rapidly.
The company's research and development of vaporized hydrogen peroxide disinfection robot kino, the use of vaporized hydrogen peroxide disinfection technology to kill various microorganisms in the air and on the surface of the object in the space. Disinfection, hydrogen peroxide will decompose into water and oxygen, will not cause pollution to the environment, non-toxic and non-residual, will not lead to the object surface moisture, corrosion is small, some difficult to wipe and spray the health of the corner are able to disinfect 360-degree dead-angle. kino using built-in WIFI and Internet of Things (IoT) technology, you can use the computer to control, but also can be used to remote control, one person to control the operation of more than one piece of equipment, and implementation of monitoring Equipment operation, complete remote troubleshooting and software upgrades, and record the disinfection parameters, and can be printed into a report, disinfection is complete, open the refrigeration circulatory system, 30min after the concentration of the probe shows that the concentration of hydrogen perchloride is low dry 1PPM, in line with occupational health and safety requirements.
