  1. Remote Diagnostic System for the Emergency Health Services ENSC 440 Project Presentation and Demonstration December 15th, 2010 Presented By: Danny Cheng, Da Zhou, Jeffrey Tam, Eric Chow, Sean Fang

  2. MediCare Solutions Team • Danny Cheng (CEO) • Biomedical Engineer • Da Zhou (VP of Operations) • Systems Engineer • Eric Chow (VP of Marketing) • Systems Engineer • Jeffrey Tam (CFO) • Electronic Engineer • Sean Fang (Chief Engineer) • Computer Engineer ENSC 440 Presentation

  3. Agenda • Introduction • Motivation • Solutions • System Overview • Handheld Tablet • Whiteboard • Database • Timeline and Budget • Future Work • Lesson’s Learned • Conclusion ENSC 440 Presentation

  4. Introduction • Total emergency health services (EHS) package • Consists of three components: • Handheld Tablet • Whiteboard • Database • Increase hospital emergency room (ER) efficiency • Reduce length of stay and cost ENSC 440 Presentation

  5. Basic Medical Process : Paramedics and Emergency Room • Paramedics ER Nurse Arrives at scene (Patient Care Report begin) Transport patient to hospital Arrives at hospital Provide triage nurse of their assessment of injury Patient admits to hospital Triage nurse starts comprehensive Triage Nursing Assessment Prioritize patient based on CTAS score (level of severity) ENSC 440 Presentation

  6. Motivation • Current Emergency Response System • Radio/Telephone Communication • Paramedic and ER nurse triage • Falling behind to demand • National benchmark is 8 hours for admitting a patient, and 4 hours for discharging a patient ENSC 440 Presentation

  7. Solution • Allow hospital to receive multiple inquiries • Efficient • Trouble-free • Reliable • Allow hospital to receive information early and prepare for incoming patients • Reduce redundancy • Enhance communication between Paramedics and Nurses ENSC 440 Presentation

  8. System Overview ENSC 440 Presentation

  9. System Flowchart ENSC 440 Presentation

  10. Handheld Tablet • Requirements: • Large Touchscreen • Wireless Network • Camera Interfacing • I/O Communication Port • Sufficient Processing Power and Memory • Easy Maintenance and Development ENSC 440 Presentation

  11. Devkit8000 Development Board • TI OMAP3530 600MHz CPU • WiFi Module • Camera Module • RS232 Serial Port • 7” LCD Touch screen • Other modules can be added easily ENSC 440 Presentation

  12. Devkit8000 Modules WiFi Module – WF8000, 802.11 b/g Ralink RT2870 Chipset FTDI FT2232C Chipset USB Camera – CAM8000, 3.2 Mega Pixel CMOS, 20 FPS ENSC 440 Presentation

  13. LCD Touchscreen • Innolux AT070TN83 • 7 Inch • 4 line resistive sensors • 800x480 Resolution • Anti-glare • 120 ~ 140° Viewing Angle ENSC 440 Presentation

  14. Plexi-glass Protective Casing ENSC 440 Presentation

  15. Tablet GUI • Design: • Intuitive • Minimal typing • Informational ENSC 440 Presentation

  16. Tablet GeneralOperation Start Display GUI Enter patient information Take wound pictures Save the information Vital Sign Measurement Send it to a hospital server Is paramedic info stored in server? Auto-fill paramedic info fields User Filled in form No Have user fill in paramedic info fields Yes Transmit data to server Create New Form End of user’s shift? Transmit to GUI No Yes Log out of user Exit ENSC 440 Presentation

  17. Whiteboard • Currently in used in hospital • Usually illustrated on giant display • Efficient information management and communication ENSC 440 Presentation

  18. Whiteboard GUI 1. Default View Mode • Top Table: • Patients waiting in ER or in treatment • Bottom Table • Patients being transported to the hospital • Detail of Patient Care Report ENSC 440 Presentation

  19. Whiteboard GUI 2. Edit Mode • Access/modify information by medical personnel on desktops/laptops • Password Protected • Access to: • Patient Care Report • Triage Nursing Assessment • Add/delete/modify patient information ENSC 440 Presentation

  20. Patient Care Report GUI • Display Patient Care Report info sent by paramedics Includes: • Patient Info • Live vital signs updates • High quality images • Display Triage Nursing Assessment info ENSC 440 Presentation

  21. High Quality Image GUI • Intended to display patient’s wounds or condition visually • 3.2Mega Pixel CMOS image sensor • 640x480 Resolution • JPEG format ENSC 440 Presentation

  22. Vital Signs GUI • Real-time update of patient’s vital signs • SPO2 • Pulse • Data will be plotted continuously ENSC 440 Presentation

  23. Triage Nursing Assessment GUI • Used by triage nurses for comprehensive assessment • Create/Update Triage Nursing Assessment • Patient searching functionality via CareCard # ENSC 440 Presentation

  24. Database Server Layout ENSC 440 Presentation

  25. Timeline Actual Planned ENSC 440 Presentation

  26. Budget ENSC 440 Presentation

  27. Future Work • Implement level III and IV features in the functional specification • 3G networking • Battery pack and power management • 10” Display • Touch Screen performance • Design a nicer and more compact casing • Prototype field test by the paramedics ENSC 440 Presentation

  28. Lessons Learned • User Interface Design • Embedded Linux Programming • Database Design and Construction • Wireless Communication • Image Capturing and Camera Interfacing • Teamwork • If you don’t know it, learn it and apply it! ENSC 440 Presentation

  29. Conclusion • System designed to improve efficiency at ER • A proof-of-concept model is constructed and tested • Future works concentrated on system performance and user feedbacks • Great course! • Wonderful experiences! ENSC 440 Presentation
