Daily validation and monitoring methods for dental high-pressure sterilizers

To ensure sterilization effectiveness, a comprehensive quality monitoring system must be established. Physical monitoring: Temperature, pressure, and time recording curves need to be checked every time it runs to ensure compliance with set parameters. Chemical monitoring: Each package contains a built-in chemical indicator card, and when the color changing block reaches the specified color, it indicates that it has been exposed to effective sterilization conditions; The color changing stripes on the external adhesive tape can distinguish between sterilized and unsterilized items. Biological monitoring: Use thermophilic Bacillus spores test paper as the gold standard, at least once a month, and culture for 48-72 hours to confirm no bacterial growth before release. After daily use, the chamber, door seal, and drainage filter should be cleaned to prevent residue accumulation. Perform a cavity descaling program once a week and use specialized cleaning agents to remove scale. Record the parameters and monitoring results of each batch of operation, and establish traceable sterilization records. If the biological monitoring is positive, the equipment must be immediately stopped, all recent instruments must be recalled for re sterilization, and the cause of equipment failure must be investigated.
