Design And Implementation Of Medical Device Service Platform Based On Micro Service Architecture

In recent years,with the aging of population and the increase of sub-health population,the demand for medical devices in domestic hospitals and medical institutions increased year by year in the outbreak of New Coronavirus worldwide in2020.Major medical device R ＆D and production companies have expanded the scale of device production.The traditional medical device service platform of the author’s company is built with a single architecture,resulting in problems such as high functional coupling,degraded performance,long development and testing cycle and so on.At the same time,when the system is faced with high concurrent business scenarios such as online delivery,equipment installation and maintenance,system downtime often occurs,which seriously affects the user experience and the company’s business operation.The medical device service platform based on the micro-service architecture designed and implemented by the author of this paper uses the micro-service design idea to restructure the medical device service platform at the interface level,and optimizes the core load balancing algorithm in the service platform,which significantly improves the response of the service platform.Efficiency and service quality.The main research contents of this paper are as follows:（1）Introduce the theoretical basis related to the micro-service architecture,design the medical device service platform by using the micro-service design idea,and discuss the feasibility of the micro-service design idea and architecture in the medical device service platform.（2）Investigate and analyze the characteristics and functional requirements of medical device business,integrate Spring Cloud components,including service gateway,service registry and load balancing components,so as to build the service governance mechanism in the system,and complete the coding of the core business module on this basis.（3）Aiming at the problem of high concurrent traffic in a specific enterprise scenario,the minimum connection algorithm built into the Ribbon load balancer is optimized and transformed,and a dynamic weighted minimum connection number algorithm based on entropy weighting method is proposed,and the algorithm is used.Successfully applied to the refactored service platform.The test results show that the medical device service platform based on the micro-service architecture has improved system scalability and maintainability,and the overall performance of the service platform has been improved,which proves that the system can better meet the needs of rapid iteration of the medical device business.The system performance requirements have certain feasibility and reference significance.
