sterilization
The process of killing or removing all microorganisms from medical devices, utensils, and items.
disinfect
Remove or kill pathogenic microorganisms on the transmission medium to achieve harmless treatment.
Sterilization level
Kill all microorganisms, including bacterial spores, to achieve a level of sterility assurance. Common methods to reach the sterilization level include physical sterilization methods such as thermal sterilization and radiation sterilization, and chemical sterilization such as ethylene oxide, chlorine peroxide, formaldehyde, amyl aldehyde, Peracetic acid under specified conditions. The method of sterilization with appropriate concentration and effective action time.
High level disinfection
Kill all bacterial Propagule, including mycobacteria, viruses, fungi and their spores, and most bacterial spores. The commonly used methods to achieve a high level of disinfection include the use of chlorine containing preparations, Chlorine dioxide, phthalaldehyde, Peracetic acid, hydrogen peroxide, ozone, iodine tincture, etc., as well as chemical disinfectants that can achieve sterilization effects under specified conditions, with appropriate concentrations and effective action time.
Medium level disinfection
Kill various pathogenic microorganisms, including Mycobacterium, except for bacterial spores. The commonly used methods to achieve the medium level of disinfection include the use of iodine disinfectants (iodophor, chlorhexidine iodine, etc.), alcohols and Chlorhexidine compound, alcohols and Quaternary ammonium cation compound, phenols and other disinfectants. Under the specified conditions, disinfection methods are carried out with appropriate concentration and effective action time.
Low level disinfection
Chemical disinfection methods that can kill bacterial Propagule (except mycobacteria) and lipophilic viruses, as well as mechanical sterilization methods such as ventilation and washing. For example, use quaternary ammonium salt disinfectant (benzalkonium bromide, etc.), Biguanide disinfectant (chlorhexidine), etc. Under specified conditions, use appropriate concentration and effective action time for disinfection
