Design and Implementation of a Medical Device Data Dictionary System Based on Software Engineering Theory

Objective: Based on software engineering principles, we designed and implemented a medical device data dictionary system that aligns with data integration and industry standards to fulfill the data management needs of medical institutions and healthcare professionals. Materials and Methods: Utilizing the web-based framework alongside open-source technologies such as Spring Boot, Spring Security, Apache MyBatis, Vue, and Element UI, along with database technologies such as MySql, MongoDB, and Redis, we analyze the basic elements of medical device data dictionary system and incorporate layered architecture technology, design the system architecture, functional workflows and database model required for the dictionary system, and conduct professional testing and trial evaluation of the system. Results and Analysis: In this study, we constructed a web-based open medical device data dictionary system that supports front-end and back-end operations. Using a ventilator as a sample for non-integrity assessment, the results of the system utility test showed that the system is functionally complete, satisfies the compatibility requirements of mainstream browsers and poses no significant risks or vulnerabilities to system operation. Conclusion: A medical device data dictionary that characterizes life cycle usage attributes based on their structural and functional properties was constructed. It provides a unified and standardized base for the management and analysis of medical device data, and helps realize the interaction and exchange of medical device data between disparate medical information systems.
