The female menstrual cycle tracking ring is a smart wearable device specifically designed for women, primarily used for tracking and monitoring women's menstrual cycles. It falls into the category of medical devices and requires registration approval from the National Medical Products Administration (NMPA) to be launched in China.

Below is an overview of the NMPA registration process for such smart rings:

I. Product Classification and Definition

1. Determine Medical Device Classification:
   According to the Classification Directory of Medical Devices, smart rings with monitoring functions such as blood pressure, blood oxygen, and heart rate are typically classified as Class II medical devices (specific classification requires further confirmation based on product functions and risk levels). If the product involves diagnostic functions or high-risk monitoring functions, it may be classified as Class III medical devices.

2. Product Naming and Description:
   Clearly define the product's name, model, functional description, scope of application, etc., as required by the NMPA.

II. Prepare Technical Documents

1. Product Technical Files:

• Product Technical Requirements: Including performance indicators, testing methods, safety standards, etc.

• Product Manual: Detailedly describe product functions, usage methods, contraindications, precautions, etc.

• Design Drawings and Principle Descriptions: Including hardware design, software algorithms (such as blood pressure and blood oxygen monitoring algorithms), etc.

• Manufacturing Process: Production processes, key process parameters, etc.

2. Risk Management Documents:

• Risk Assessment Report: Identify potential risks of the product (such as measurement errors, data security, etc.) and propose control measures.

• Risk Control Measures: Ensure the safety of the product under normal use conditions.

3. Software Research Materials (if applicable):
   If the product contains software (such as data analysis, monitoring algorithms, etc.), submit software description documents, including software architecture, algorithm principles, network security measures, etc.

III. Quality Management System

1. Establish a Quality Management System:
   Establish a quality management system according to the Good Manufacturing Practice (GMP) for Medical Devices and obtain ISO 13485 certification. Ensure that design and development, production, inspection, sales, and other processes comply with NMPA requirements.

2. System Verification:
   The NMPA may conduct on-site inspections of the production site to confirm the effectiveness of the quality management system.

IV. Product Testing

1. Type Testing:

• Electrical safety (e.g., GB 9706.1)

• Electromagnetic compatibility (EMC)

• Performance testing (e.g., accuracy of blood pressure, blood oxygen, and heart rate measurements)

• Environmental adaptability (e.g., temperature, humidity, vibration, etc.)

• Send the product to an NMPA-approved testing institution for testing. Testing items include but are not limited to:

• Obtain a qualified test report.

• Testing Standards:

2. Clinical Evaluation:

• For blood pressure, blood oxygen, body temperature modules, atrial fibrillation, respiratory rate, etc., clinical accuracy verification is required to demonstrate the product's safety, effectiveness, and accuracy.

V. Prepare Registration Application Materials

1. Registration Application Form:

• Fill out the NMPA Medical Device Registration Application Form, clearly stating product information, applicant information, etc.

2. Technical Documents:

• Including product technical requirements, manuals, risk management documents, software research materials, etc.

3. Quality Management System Documents:

• Provide relevant certificate documents of the quality management system.

4. Test Reports:

• Submit type test reports.

5. Clinical Evaluation Materials:

• Submit clinical evaluation reports or clinical trial reports (if applicable).

VI. Submit Registration Application

1. Online Submission:

• Submit registration application materials through the NMPA Medical Device Electronic Reporting System.

2. Fee Payment:

• Pay the registration fee according to NMPA regulations.

VII. Technical Evaluation

1. NMPA Evaluation:

• The NMPA conducts a technical evaluation of the submitted materials and may request supplementary materials or conduct on-site inspections.
