Aiming at the centralization problem of the traditional medical device traceability system. This paper proposes a medical device traceability system based on blockchain technology. By integrating the traditional tracing system with the blockchain technology, based on the decentralization and non-tamperability of the blockchain, the alliance chain and the smart contract construction system are adopted. Manufacturers, distributors, hospitals and consumers in the system can access product

In addition, consumers do not need to register an account number, but directly through the RFID query products related to the main information, such as the shelf life, production enterprises, production time, product price, etc. This system solves the problem that the traditional system is vulnerable to network attack due to centralization, which can improve the robustness of the system, enhance the reliability of data and realizes the traceability of the production, sales and use of medical devices. Therefore, it ensures that the source of medical devices can be traced, the flow can be tracked, the information can be inquired and the responsibility can be investigated to ensure the public consumption safety.
