Process and effect of sterilization validation
Process for 1. Sterilization Validation
Sterilization validation is a key link to ensure the reliability and effectiveness of the sterilization process and the sterility of the product. The process mainly includes the following steps:
1. Equipment preparation: Select the appropriate sterilization equipment, perform the necessary cleaning and pre-hot spots.
2. Product loading: According to the specified loading method and quantity, put the product to be sterilized into the sterilization equipment.
3. Setting parameters: According to the characteristics of the product and sterilization requirements, set the temperature, pressure, time and other parameters of the sterilization equipment.
4. Implementation of sterilization: according to the set parameters, start the sterilization equipment, sterilization operation.
5. Cooling and unloading: After sterilization, perform necessary cooling operations, and then remove the product from the sterilization equipment.
6. Data analysis and recording: Collect and analyze the data in the sterilization process, and record the key parameters and results of the whole process.
Effect of 2. sterilization validation
The effectiveness of sterilization validation is evaluated in the following ways:
1. Microbial challenge test: by inoculating specific microorganisms to the product to be sterilized, and then operating according to the set sterilization process, and finally detecting the survival of microorganisms to evaluate the sterilization effect.
Physical performance testing: detect whether the physical properties of the product have changed, such as packaging integrity, product form, etc.
Chemical indicator detection: Use chemical indicators to monitor key parameters in the sterilization process, such as temperature, pressure, etc., to verify whether these parameters meet the requirements.
4. Comprehensive evaluation: Combined with the results of microbial challenge test, physical performance test and chemical indicator test, the sterilization effect is comprehensively evaluated. If all the indicators meet the requirements, the sterilization validation is successful.
In short, sterilization validation is an important part of ensuring product sterility. Through reasonable process and strict testing, the reliability and effectiveness of the sterilization process can be ensured, thereby ensuring the quality and safety of the product. In actual operation, it is also necessary to continuously optimize and adjust the sterilization verification process and method according to the product characteristics and sterilization requirements to improve the sterilization effect and quality.
