[Exploration of the Application of Blockchain in Medical Engineering]

Blockchain technology, with its characteristics of decentralization, immutability, traceability, and high transparency, offers innovative solutions for the innovative development of the medical engineering field. As a key support for ensuring the quality, safety and efficiency of medical care, the medical engineering field is currently facing multiple challenges such as complex medical device management, severe data silos, opaque supply chains and prominent information security risks. This paper systematically summarizes the research status and development trends of blockchain in the medical engineering field. Firstly, it elaborates on the basic principles of blockchain technology and its high compatibility with the demands of medical engineering. Secondly, it focuses on three core dimensions: the full life cycle management of medical device, the security and sharing of medical device data, and the management of medical device and consumables supply chains, to deeply analyze the main application scenarios, key technologies, and existing research progress of blockchain. Thirdly, this paper discusses the typical architecture of medical engineering application systems based on blockchain and integrates and analyzes the empirical data on key performance indicators in existing research. Fourthly, this paper systematically summarizes the multi-dimensional challenges faced by the application of blockchain technology in the medical engineering field, including technical, regulatory, cost and organizational aspects, and conducts a comprehensive assessment of its feasibility. Finally, it looks forward to the future research directions in this field.
