In recent years，in response to public health emergencies，the State Drug Administration has repeatedly initiated the emergency examination and approval of medical devices，and the emergency approval of pharmaceutical supervisory and administrative departments at various levels has passed various epidemic prevention and control products，such as in vitro diagnostic reagents，protective clothing，medical masks，etc.，which are conducive to supporting the development of epidemic prevention and control work. This paper analyzes in details the relevant provisions of the Emergency Approval Procedures for Medical Devices on Medical Devices，and summarizes the relevant requirements of other laws and regulations on the Emergency Approval of Medical Devices，such as the Regulations on the Supervision and Administration of Medical Devices on Deepening the Reform of the Approval and Approval System for Approval of Medical Devices to Encourage the Innovation of Medical Devices. After the outbreak of COVID-19 pneumonia，the emergency examination and approval of medical devices in China has greatly promoted the supply of medical protective products，and ensured the urgent need of prevention，control and treatment of the epidemic situation. Finally，this paper summarizes the requirements of medical equipment emergency examination and approval in the United States，Japan and the European Union，and puts forward some suggestions for China to better cope with public health emergencies and further meet emergency needs.
