The Requirement Analysis And Design Of Remote E-health Monitoring System

The digitization of healthcare provides convenience to share and utilize medical data of the whole society. Comprehensive diagnosis and treatment needs integrating the information from the patient in all respect. But, the hospital environment is complex and different department needs different requirement. That is why there is a large number of heterogeneous, autonomous and distributing equipments, databases and information systems. In this way, the interoperability of the systems is more and more important. Creating a solution to seamlessly integrate existed hospitals, projects and devices without revealing the internal details; new systems and projects can also be built easily by the same solution; in the mean time, protecting the security of the data exchange between systems.Luxembourg e-health project RESIST defines an architectural framework to guide engineers to design and connect medical services within an e-health platform. It abstracts services components as the results of different layers in an SOA architecture, which brings loose coupling and improves the interoperability to the project.This thesis work is extending and verifying the existing RESIST result. Based on the original architecture, this thesis first gives a bottom-up resource description method, then proposes a list of (not limited to)information to describe each service model, which improves the services management and interoperability. In addition, the definition of a standard set of properties that describes a service can help to design the database structure.In addition, based on RESIST solution and Luxembourg e-health environment, this thesis describes the whole process of designing and implementing a patient monitoring system prototype. The requirement analysis lists real scenario and gives the system requirement from three aspects: business requirement, technical requirement and the relationship between them. Then the non-functional requirement is introduced. In the design phase, the services are integrated by the architecture definition and the described by the service description defined in this thesis. In the implementation phase, we use the open source ESB environment to introduce medical data exchange standard (HL7) and security protocol (WS-Security), which improve the interoperability of medical data communication and guarantee the communication security. The prototype's result gives the possibility that different teams can develop applications in their own aspect without disturbing each other and verifies the efficiency of RESIST.
