In public health emergencies or other emergencies that seriously threaten public health，the supply of medicine，medical devices and other medical products is an important guarantee to effectively respond to emergencies. Although there are many systems to realize the accessibility of medical devices in China，such as Emergency Approval Procedures，Priority Approval Procedures，Special Review Procedures for Innovative Medical Devices，Expansion Applications in Clinical Trial，and Conditional Approval，etc.，but due to the different goals and limitations of various procedures，they can not fully meet the needs of medical devices in emergency. Therefore，in order to achieve the accessibility of medical devices in emergency situations，we should not only improve the current emergency approval system of medical devices，but also build a new system of Emergency Use Authorizations about medical devices in the future.
