Sterilization quality monitoring methods include the use of biological indicators, physical indicators, chemical indicators and so on.
1, biological indicators.
Use of biological indicators containing high resistance, such as spores or viruses, placed in the sterilization process for monitoring. By detecting whether the bioindicator is effectively inactivated to assess the sterilization effect. Bioindicators are commonly used in areas such as environmental monitoring, ecological assessment and biodiversity research.
2, physical indicators.
The use of physical parameter monitoring equipment, such as thermometers, manometers, time recorders, etc., to record key parameters of the sterilization process to ensure that the sterilization process meets preset conditions. An indicator is a device or method for measuring or indicating some physical quantity or phenomenon.
3, chemical indicator.
The use of chemical indicators, such as sterilization indicator paper or sterilization indicator strips, placed in sterilization packages or containers, through color changes or other chemical reactions to indicate whether the sterilization process meets the requirements. It can be used in the laboratory or in industry to help detect, mark, or indicate a property or change in a chemical reaction process.
The role of sterilization:
1, prevention of infection.
Sterilization can effectively reduce or eliminate the presence of pathogenic microorganisms on objects, equipment or surfaces, thereby preventing the spread and propagation of infection. In hospitals, laboratories and operating rooms and other environments, sterilization can protect the health and safety of health care workers and patients.
2, to ensure product quality.
Sterilization is an important step to ensure product quality and safety in the pharmaceutical, food processing, medical equipment and other industries. Through sterilization, you can eliminate pathogenic microorganisms in the product to ensure that the product does not cause disease or contamination.
3, to extend the shelf life of the goods.
For certain foods, medicines or other goods that are susceptible to microbial contamination and corruption, sterilization can extend their shelf life and maintain the nutritional value and quality of the product.
4, research and experimental uses.
In laboratory research, sterilization is commonly used to eliminate bacteria or other microorganisms in the environment and experimental materials to ensure the accuracy and reliability of experiments.
