  1. University of Pittsburgh Senior Design - BioE1160 ECMO Circuit Pressure AlarmPROJECT PROPOSAL Desiree Bonadonna Apryle Craig Laura Gilmour ECMOre, Uninc.

  2. Overview • ECMO Pressure Alarm • Pre-Oxygenator • Post-Oxygenator • Post-Heat Exchanger • Audible and Visual Alarms • Make healthcare workers aware of high/low pressures • Dangers of high/low pressures • Healthcare Workers • Perfusionists • ECMO Technicians • Physicians • Nurses • Redesign • Analog  Digital • Programmable • Audible Alarm • Add additional pressure indicator (post heat-exchanger)

  3. Project Goals • Develop digital pressure alarm system • Simulink model • Build model • Submission for FDA approval • Milestones • Current technology summary • Re-assess project goals • Redesign • Add programmable inputs • Add alarm • Add sound • Deliverable

  4. Features & Benefits • Three inputs • Monitor pressure pre- and post-oxygenator • Monitor pressure pre- and post-heat exchanger • Digital System • Reduce interpretation errors • Clear and easy to understand • Consistency • Three read-outs • Clear display of each pressure • Three pressures can be monitored and compared at same time

  5. Features & Benefits • Programmable range • Adjust high and low alarm range per patient basis • Allows for variable sensitivity of system • Audible and Visual Alarms • Alert staff by audible alarm • Notify particular pressure deviance by visual alarm

  6. Description: Circuit Modification

  7. Description: Device Circuitry

  8. Design Alternatives • Types of Displays • Number of Audible Alarms • Number of Visual Alarms • Alarm independence/convenience

  9. Competitive Analysis Current Medically approved devices • Analog • Difficult to read • Not clearly labeled • No audible • No visual alarm Non-approved devices • Digital with visual alarm

  10. Competitive Analysis ECMOre Design weaknesses • More expensive than analog • More tubing in an already cluttered space • Increased training time/expenses

  11. Technology • Altera circuit design software • SolidWorks for enclosure • SimuLink • Model an ECMO circuit using water • Experiment with transducer voltages • Test final product

  12. Team/Resources Team • Desiree Bonadonna- Design Manager • Apryle Craig- Electronics Manager • Laura Gilmour- Standards Manager • Michael Shaeffer- Project Advisor • Steven Jacobs, PhD- Circuitry Advisor Equipment • Electronics ordered from University Vendor • Tools/signal generators available in B69

  13. Team/Resources Locations • Instrumentation Laboratory- B69 Benedum • Design Laboratory- B62 Benedum Healthcare consultation- Children’s Hospital of Pittsburgh Manufacturing • UPMC Machine Shop (Scaiffe Hall) • UPMC Electronics Shop (Scaiffe Hall) Funding • University of Pittsburgh Department of Bioengineering

  14. Schedule

  15. Team Roles

  16. Current Status • Met with both advisors • Visited Children’s ECMO services • HFE Analysis, FMEA • Determined regular meeting time for next semester

  17. Acknowledgements University of Pittsburgh Department of Bioengineering Mark Gartner Michael Shaeffer Steven Jacobs
