Judging the sterilization effect of an autoclave usually requires detection and evaluation in multiple aspects such as biological indicator testing, physical indicator monitoring, and chemical indicator monitoring.
Biological indicator test: After running the autoclave for a certain period of time, take out the processed biological indicator placed in the sterilizer and test it to confirm whether it meets the sterilization standards. Biological indicators usually use spores, such as hell spores, subtilis spores, etc.
Physical indicator monitoring: Physical indicators include the internal temperature, pressure, humidity, etc. of the sterilizer. These indicators are usually displayed on the sterilizer operation panel. You can judge whether the operating status and sterilization effect of the sterilizer meet the standards based on the indicated values. .
Chemical indicator monitoring: Chemical indicators include the pH value, conductivity, dissolved oxygen content, etc. of the water inside the sterilizer, which can be monitored through water quality detectors and other equipment. By detecting these chemical indicators, it can be judged whether the water quality meets the sterilization requirements, thereby evaluating the sterilization effect.
Visual inspection: After sterilization, check whether the items show the characteristics required for the sterilization effect, such as whether the color, texture, shape, etc. have changed.
Internal inspection: Check the internal components and pipes of the sterilizer to ensure that they are intact and free of contamination, and whether they need to be cleaned or replaced.
Operation log: record the specific parameters and time of each sterilization operation to facilitate subsequent tracing and evaluation of the sterilization effect.
Operator training and management: Provide professional training to operators to master the correct operation methods of the sterilizer, thereby improving the sterilization effect and reducing the impact of improper sterilization operations.
Regular maintenance: Perform regular maintenance on the sterilizer, including cleaning, disinfection, replacement of parts, etc., to ensure that it operates normally and achieves sterilization effect.
External monitoring: Entrust a third-party organization to monitor the sterilization effect of the sterilizer to obtain objective evaluation results.
Isolation: Isolate items that fail to sterilize or do not meet standards to prevent them from causing contamination and harm to other items or the environment.
