Design and implementation of integration architecture of ISO 11073 DIM with FHIR resources using CoAP

The Internet of Things (IoT) is an extension and expansion of the Internet which is extensively deployed in the healthcare field. With the proliferation of Personal Health Devices (PHDs), there is a significant incompatibility issue where devices use special data transfer protocols and can only communicate with special healthcare providers from the same manufacturer, thus interoperability and network energy consumption features become important issues. In this paper, we design and implement an integration architecture of ISO 11073 DIM with FHIR resources using CoAP to exchange health information between personal health devices and healthcare providers for solving communication consumption issues and standardization issues. We design and implement an ISO/IEEE 11073 translator gateway for device standardization and an ISO/IEEE 11073/FHIR translator gateway for Electronic Health Record (EHR) standardization. In addition, we use CoAP as data transfer protocol. An android application that is developed acts as a health manager for healthcare consumers. We used SpO2 as personal health device to measure and deliver the health data to test this architecture.
