1. Medical device products have market access requirements, and the supervision is very strict.
2. Non-medical device products have no clear market norms, and the supervision is not as strict as that of medical devices. Medical devices refer to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrations, materials and other similar or related items directly or indirectly used in human body, including required computer software. Medical devices include medical devices and medical consumables, and their effectiveness is mainly obtained by physical means, not by pharmacology, immunology or metabolism.
