When purchasing and using home medical devices, you must follow a doctor's guidance. Medical devices are intended for disease diagnosis and treatment. Consult your doctor before buying them and use them under professional instruction. Have your doctor regularly assess the effectiveness of use and check for adverse reactions to avoid health damage caused by improper use.

Read the product manual carefully before purchase. Consult sales staff or doctors to fully understand the product's working principle, scope of application, usage methods, precautions and contraindications. Make your purchase and usage decisions based on professional advice and your personal physical condition.

Key Points for Purchasing Home Medical Devices

1. Verify the seller's qualifications Buy products from regular pharmacies or licensed medical device distributors. Check whether the seller holds valid credentials including the Medical Device Business License (or filing certificate) and Business License, and confirm reliable after-sales service.

2. Check product certifications Legitimate medical devices must have a Medical Device Registration Certificate (or filing certificate) and a Medical Device Production License (or filing certificate). To verify authenticity, visit the official website of the National Medical Products Administration. Navigate to the data query section, select medical devices, and enter the registration certificate number or product name to conduct nationwide inquiries. Note that some ordinary goods falsely claim therapeutic effects, such as height increasing devices and weight loss devices. Daily fitness equipment, as well as clothing, hats, shoes, socks, bracelets, earrings and other items with health-care functions, do not belong to medical devices.

3. Request a formal invoice Always ask for a standard purchase invoice when buying medical devices. An official invoice serves as valid proof of purchase, which is essential for product warranty and quality complaints. Unlicensed vendors usually do not provide formal receipts, so do not seek convenience or chase low prices at the expense of legitimate guarantees.

To verify product authenticity, log on to the official website of the National Medical Products Administration. In the data query section, click the medical device entry and input the registration certificate number or product name to search for relevant information nationwide.
