Remote Non-Intrusive Patient Monitoring

The Tyndall-DMS-Mote is a wireless sensor device that can monitor patient vital signs non-intrusively within and outside their home. Patient real-time vital sign readings (dynamic data) and archived records (static data) need to be managed, correlated and analysed in a cohesive manner to produce effective results. The Data Management System (DMS) has been developed to intelligently manage this data. Limited computation is available to clients executing on the sensor node. Presented is a Mobile-DMS-Client which executes on a Nokia 9500 Communicator. This client complements the Tyndall-DMS-Mote in its ability to locally process larger amounts of data thus reducing the need to communicate data to a remote server for computation. When external interaction is required (e.g. to a knowledge base or staff PDA) the DMS can supply information via a context aware agent middleware. Agents effectively encapsulate, extract and interpret real world context aware information ensuring physicians get the "correct" data on time every time. Patient vital sign readings are taken by Tyndall-DMS-Motes in a noninvasive non-intrusive manner. Details are given on the Mobile-DMS-Client and Tyndall-DMS-Mote prototypes and their ability to interpret patient blood pressure sensor readings.
