PBAT medical application verification
Problem Phenomenon
PBAT medical application biocompatibility and degradation matching, insufficient verification.
Cause Analysis
PBAT medical application biocompatibility; degradation rate matching with tissue; sterilization influence; long-term performance; regulatory requirements.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Biocompatibility testing; ②degradation rate regulation; ③sterilization verification; ④long-term performance; ⑤regulatory compliance.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBAT medical application is a high-end field; comprehensive verification is the prerequisite; compliance ensures market access.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
