The imperfect staffing in pre-hospital first aid and the unreasonable dispatching of ambulances pose a threat to the life and health of the public. In order to solve the above problems, this paper proposes an emergency rescue system based on metaverse, which adds the function of personal doctor on the basis of the shared vehicle scheduling system based on blockchain. Metaverse is the fusion and interaction between the virtual and the real world, with blockchain, smart contracts, and other main technologies. Through the combination of metaverse and intelligent doctor assistant, the function and use process of personal doctor are designed. This paper also proposes an insurance-like payment mechanism, which is based on the premise of controlling the packing order of transactions in the blockchain by controlling the level of Gas Price and solving the problem of who pays and how to pay the transaction fee of the system. It not only ensures the normal operation of emergency rescue activities but also protects the interests of each node in the blockchain.
