Presentation Transcript

  1. Telemedicine and Assistive Technology Ronald Merrell, MD, FACS Azhar Rafiq, MD, MBA Virginia Commonwealth University, MITAC Richmond Virginia Meditac.com

  2. The Astronaut in a Hostile and Remote Environment • Apprehend the physiologic status • Collate the data • Interpret the data locally • Propose and realize a response • Record the event and transmit to a distant management site • Design, validate and implement sensor network for semi-autonomous physiological monitoring system.

  3. Analogies for Assistive Technology Requirements • Medical situations or probabilities that require prompt response and might otherwise confine the individual to a strictly monitored environment • Desire for maximal independence of mobility and location • Need for local prompt alert and response while maintaining strong connection to a distant management site • Great technical solutions for sensing, data management and telecommunications awaiting application

  4. Program Description Sensor network Data sampling and conditioning Data pre-processing Data archive and analysis Data communication VPack

  5. Sensor network • Skin Surface Temperature • Galvanic Skin conductance • Pulse Oximeter - Heart Rate • Pulse Oximeter - Oxygen Saturation (SpO2) • Plethysmograph – Blood Volume (Perfusion)

  6. Advanced EVA Desert RATS 2005 CAIpack CAI-1 SCOUT CAI-2 Hab RV SCOUT Camp

  7. Bio Sensor Network • Physiological sensor network in direct contact with skin • Integrate sensor signals into a single feed to computer with VPack • All wires from sensors • embedded inside sock • to prevent tear in suit bladder Pulse oximetry sensor Skin Temperature sensor Galvanic Skin Resistance Liquid cooling garment (overlay)

  8. Data archive and analysis • ASCII file format with fixed column format • Date and time stamp • Data analysis algorithm • Alerts communication with text message to cell phone

  9. Data display interface

  10. Diabetes monitoring applications Alarm - text message Chronic care- Diabetes monitoring Software interface Demonstration b/w San Francisco and Virginia – Diabetes technology conference

  11. Passive Wireless Monitoring for Signs of Hypoglycemia Ronald C. Merrell, MD, FACS Virginia Commonwealth University Richmond, Virginia

  12. HYPOMON HypoMon™ MEASURES EKG AND SKIN IMPEDANCE

  13. Assistive Living Applications • Activity • Location • Vital signs • Acute change alarms • Trending alerts • Messaging to reconfirm regimen and refine response to changes

  14. Assistive Living Applications • Alzheimer Syndrome • Physical impairment due to neurological injury • Congestive heart failure monitoring • Diabetes mellitus monitoring • Arrhythmia monitoring • Sleep pathology • Fall alerts • Alerts for loss of consciousness • Seizure alerts • Monitoring for peripheral vascular disease • Home or out of home
