摘　　要：为提高医疗器械追溯管理质量,针对传统追溯系统信息不对称、数据中心化等问题,将区块链的去中心化、智能合约、非对称加密等技术与我国现有医疗器械追溯流程相结合,从运行流程、智能合约、信息加密体系、系统架构几个方面设计了基于区块链技术的医疗器械全流程追溯系统,可有效解决产品流向不具体、责任主体不明确、数据易被篡改等问题。通过设计链上链下相结合的信息存储查询模式,使系统在满足业务需求的同时,保证了运行效率。To improve the tracing quality of medical devices,this paper integrates the decentralization,smart contracts,asymmetric encryption,and other technologies of the block chain with it.Aiming at information asymmetry and data centralization of traditional traceability systems,a full-process medical device traceability system based on the blockchain technology is built in terms of the operation process,intelligent contract,information encryption system,and system architecture.This system effectively solves many problems such as uncertain product flow,unclear responsible body,and easily tampered data.In addition,a combination of information storage and query model is designed to meet the business requirements and ensure the traceability efficiency.
