A Programmable Service Architecture for Mobile Medical Care
Fourth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOMW'06)
We introduce MobiCare -a remote wireless patient monitoring system that exploits the recent advances in clinical sensor/actuator systems and wide-area wireless communication networks to provide better healthcare services in a wide-range of scenarios. MobiCare consists of three important building blocks: a body sensor network (BSN) consisting of wearable sensors and actuators with wireless inter-connections; a BSN Manager (also called Mo-biCare client) that connects the BSN to an 'always-on'
... an 'always-on' wide-area communication interface using wide-area cellular wireless link; and back-end infrastructure support (MobiCare servers) at healthcare providers to implement necessary healthcare functionalities. MobiCare enables a wide-range of programmable and reconfigurable services with efficient remote monitoring for mobile patient care. Some of these services include: (1) health-related services in medical devices and sensors to be remotely installed, self-activate, reconfigure or even self-repair with new health services and/or applications, (2) secure and reliable remote dynamic software upgrades or updates services applied to the native code of the clinical device, and, (3) remote registration and (re)configuration of body sensors as well as remote health data services such as patient health report downloads and diagnosis data uploads with provider servers. Collectively these services in MobiCare address a range of patient medical monitoring needs by accelerating deployment of new health-related services, thus reducing medical costs and improving the quality of patient care. We have implemented an initial proof-of-concept prototype of a MobiCare client and we demonstrate its feasibility in an experimental wireless testbed consisting of short-range Bluetooth and GPRS/UMTS cellular network infrastructure. We believe that MobiCare is a feasible and useful infrastructure paradigm for the next generation healthcare.
