Validation Of An ETO Sterilization Cycle
To ensure the safety and efficacy of medical devices, ที่ เอทิลีนออกไซด์ (ไลน์อัพ) การทำหมัน process must undergo a rigorous validation procedure. This process confirms that the equipment consistently delivers the required sterility assurance level (สล) for specific products.
ที่ “ฆ่ามากเกินไป” / Half-Cycle Method
In accordance with ไอเอสโอ 11135, ตัวชี้วัดทางชีวภาพ (ทวิ) are used to challenge the cycle. The logic is as follows:
- ครึ่งรอบ: Demonstrates a 6-การลดบันทึก of the most resistant microbiological challenge. Three successful half-cycle experiments are required.
- Full Cycle: By doubling the exposure time of a successful half-cycle, we provide a 12-การลดบันทึก, ensuring absolute product safety.
- Annual Revalidation: Performed yearly to confirm that process parameters remain effective.
Critical Testing for ETO Validation
Validating an EtO cycle requires more than just biological monitoring. Routine bioburden testing is essential to detect any changes in manufacturing, environment, or packaging. Essential tests include:
- Bioburden Monitoring
- Bioburden Validation (Recovery Efficiency)
- Sterility Testing
- Ethylene Oxide Residuals Testing
- Bacterial Endotoxin Test (BET)
- Bacteriostasis-Fungistasis Testing
