Purchase and Use Under a Doctor's Guidance
Medical devices are used for the diagnosis and treatment of diseases. Before purchasing, consult a doctor and use them under their guidance. Regularly have your doctor evaluate the effectiveness of use and check for adverse reactions to prevent misuse and health damage.
Carefully Read the Product Instructions
Before purchasing a medical device, carefully read the product instructions, consult with the salesperson or doctor, and understand the product's mechanism of action, scope of application, usage methods, precautions, contraindications, etc. Choose to purchase and use based on your doctor's advice and your own condition.
Verify the Seller's Qualifications
Purchase from reputable pharmacies or medical device distributors, and verify that they possess a Medical Device Business License (or Filing Certificate) and business license, and that after-sales service is guaranteed.

Verify Product Qualifications
Medical device products should have a Medical Device Registration Certificate (or Filing Certificate) and a Medical Device Production License (or Filing Certificate). To verify authenticity, you can check on the website of the National Medical Products Administration. In the data query section, click on "Medical Devices," enter the registration certificate number or product name, and you can find products nationwide. It's important to note that some ordinary products are misleadingly advertised as having therapeutic effects, such as height-increasing devices, weight-loss devices, everyday fitness equipment, and some clothing, hats, shoes, socks, bracelets, and earrings with health-related functions; these are not medical devices.
Always Obtain an Invoice
An official invoice is proof of purchase and is very useful in product warranty and quality complaint cases. Some illegal sellers often do not provide official invoices, so never try to save time or save money.
