Explanation
It refers to the use of killing pathogenic microorganisms on the transmission medium and eliminating pathogenic microorganisms outside the human body. Cut off the transmission route of infectious diseases and achieve the goal of controlling infectious diseases. The disinfection mechanism mainly involves oxidizing or other chemical reactions with microbial proteins, disrupting microbial cell walls, altering the permeability of cell membranes and the colloidal properties of protoplasm, altering the DNA or KNA of organisms, and inhibiting enzyme activity. According to its action level, it can be divided into pyrogen, high efficiency, medium efficiency and low efficiency disinfectant. The sterilizing agent can kill all microorganisms to meet the sterilization requirements, including formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxide, chlorine dioxide, chlorine, copper sulfate, quicklime, ethanol, etc. The highly effective disinfectant can kill all bacterial propagules (including mycobacteria), viruses, fungi and their spores, and can also kill bacterial spores to a certain extent, meeting the requirements of high-level disinfection. Including chlorine containing disinfectant, ozone, methyl hydantoin compounds, double chain quaternary ammonium salts, etc. Medium effect disinfectant can only kill microorganisms such as mycobacteria, fungi, viruses and bacterial propagules to meet the disinfection requirements, including iodine containing disinfectant, alcohol disinfectant, phenol disinfectant, etc. Low effective disinfectant can only kill bacterial propagules and lipophilic viruses, meeting the requirements of disinfectant, including quaternary ammonium disinfectant such as benzalkonium bromide, biguanide disinfectant such as chlorhexidine (chlorhexidine), metal ion disinfectant such as mercury, silver, copper, and Chinese herbal disinfectant.
