Presentation Transcript

  1. Current Wireless Technology • Closed Circuit Television (CCTV) in Intensive Care Units • Remote Alarms

  2. Implanted Wireless Devices • Couple the sensor to the actuator • Ex. Diabetic patients • Glucose meter – implanted insulin pump • Wireless Microchips • Epilepsy • Parkinson’s disease

  3. Homecare • Continuous Monitoring of Physiologic Parameters • ECG • NIBP • SpO2 • Pill Boxes

  4. “SmartShirt” Georgia Tech Wearable Motherboard™ • Georgia Tech • Funded by U.S. military • Plastic optical fiber • T-connectors form flexible bus • ECG, RR, temperature • Ex. Geriatric / mentally ill / SIDS • Ex. Firefighting

  5. Plug-and-Play Interoperability WHY IT IS NEEDED: • Specialized applications / multiple vendors • Medical devices and clinical information systems • No time for configuration or set-up programs

  6. Plug-and-Play Interoperability FACTORS TO CONSIDER: • Safety • Unambiguous association • Reliability • HL7 Interoperability • Security • Scalability

  7. IEEE 1073 IEEE P1073.0.1.1/D01E Draft Guide for Health informatics – Point-of-care medical device communication – Technical report – Guidelines for the use of RF wireless technology (Unpublished)

  8. QoS Components Reliability Latency Priority Bandwidth (Subject to Change) Medical Device Data Categorization Alert notifications Real-time waveforms Real-time parameters Non-real-time parameters Non-real-time events Device control IEEE 1073Summary

  9. EXAMPLE: Real-time Alarm Very high reliability (100%) < 10 second latency Very high priority Low, intermittent bandwidth Real-time Waveform High reliability (10 s/day) Latency (?) High priority High, predictable bandwidth IEEE 1073QoS Requirements
