The scope of medical device registration in China, governed by the NMPA, encompasses the following key areas:

1. Device Classification: Medical devices are classified into three categories based on risk:

   • Class I: Low-risk devices requiring basic control.
   • Class II: Moderate-risk devices needing greater control.
   • Class III: High-risk devices requiring stringent regulation and approval.

2. Device Types:

   • Diagnostic Devices: Equipment used for diagnosing medical conditions, including imaging systems and laboratory tests.
   • Therapeutic Devices: Devices intended for treatment, such as surgical instruments, implantable devices, and therapeutic appliances.
   • Monitoring Devices: Devices used to monitor patient conditions, such as heart rate monitors and glucose meters.
   • Rehabilitation Devices: Equipment aiding in patient recovery and physical therapy, like prosthetics and orthotics.

3. Registration Requirements:

   • Technical Documentation: Detailed information about the device’s design, manufacture, and intended use.
   • Clinical Data: Depending on the device class, clinical trials or performance data may be required to demonstrate safety and efficacy.
   • Quality Management System: Evidence of compliance with a recognized quality management system, such as ISO 13485.

4. Manufacturing and Importation:

   • Manufacturers: Both domestic and international manufacturers must register their devices if they intend to market them in China.
   • Importation: Foreign manufacturers must comply with additional requirements, including appointing a Chinese agent or representative.

5. Labeling and Instructions:

   • Chinese Labeling: All medical devices must have labeling in Chinese, including usage instructions, warnings, and manufacturer information.
   • Compliance with Standards: Devices must conform to Chinese national standards or equivalent international standards recognized by the NMPA.

6. Post-Market Surveillance:

   • Adverse Event Reporting: Manufacturers must monitor and report any adverse events associated with their devices.
   • Market Recalls: Procedures must be in place for recalling defective or unsafe devices from the market.

7. Regulatory Submissions:

   • Registration Application: Submission of an application including all required documents, testing reports, and certifications.
   • Review and Approval: The NMPA reviews the submission, conducts inspections if necessary, and grants approval for market access.

Understanding this scope helps ensure that all aspects of medical device registration and compliance in China are addressed comprehensively.
