4. Regulatory Audits and Inspections

4.1. Preparation

• Internal Audits: Conduct regular internal audits to ensure compliance with NMPA regulations and readiness for inspections.
• Documentation: Ensure that all technical documents, quality records, and regulatory filings are up-to-date and easily accessible.

4.2. External Inspections

• Inspection Readiness: Be prepared for NMPA inspections by maintaining a well-organized and compliant technical file and quality management system.
• Compliance: Address any findings from inspections promptly and implement corrective actions as necessary.

5. Post-Market Surveillance

5.1. Monitoring

• Market Feedback: Continuously monitor device performance and user feedback. This includes tracking adverse events, user complaints, and device failures.
• Data Collection: Collect and analyze post-market data to ensure ongoing compliance and to identify any areas for improvement.

5.2. Reporting

• Adverse Events: Report any serious adverse events or device defects to the NMPA as required. Follow the regulatory timelines for such reports.
