  4. Project Description • Objective: • Update a early 1990s Portable Emergency Ventilator design to be geared to • the needs of an EMT. Also begin the benchmarking process to pave the way • for future manufacturing and commercialization. • Goals: • Maintain FDA approval • Reduce total devices weight and overall dimensions • Update control system technology • Develop unique features to give the new design a competitive edge in • the market • Create a model to fit the needs of EMTs • Develop a more intuitive Human Interface • Create a design that can be competitively priced

  5. Customer Needs

  6. Engineering Specifications

  7. Portable Design – By reducing the devices weight and modifying its dimensions the PEV became more portable. We learned that having protruding knobs pose a hazard for “catch” points and for further refinement inlaid switches or buttons could be used. Human Interface – One screen was used to display system settings and system values, this allowed for a single location of information. Also an intuitive layout of knobs and switches was used to improve usability. Control Technology - A microcontroller was used in place of the original digital and analog logic. This upgrade increases modularity of the design allows for integration of new features. Marketability – Two key features set this device apart from other in the market today. Based on research done for this project, no other devices offer a CPR mode nor do they include a Pulse Oximeter as a peripheral device. Concept Summary

  8. Understanding- In MSD1, benchmarking was done to understand what products are currently in the market similar to the PEV presented to us. Concepts- Based on the research done, a design was proposed which contained all of the features of the original design but had technological and visual updates and new features. Also the end-user for the new design was intended for EMT’s rather than a universal PEV solution. Testing- Once a design was accepted, components and parts were ordered and testing began. The individual functionality of the components was determined before integrating them into the system. Integration- After verifying the components, construction of the system began. This include the formation of the housing, placement of knobs, switches, and screen, and mounting of interior components (e.g. MCU, pump, sensor, etc.). Design Summary

  10. Component Testing Results

  11. Cost sheet

  12. Maintained same functionality as original device • All four modes work • High pressure feedback alerts the user • Controls for mode, LPB, BPM, and pressure • Two hours of battery powered run-time • Decreased weight and overall volume of unit • More ergonomic and physically appealing design Project Evaluation - Successes

  13. Unable to combine code for pulse oximeter, LCD screen, and controls into a uniform project Insufficient experience to program a display for a larger LCD screen Unable to integrate the mass flow sensor to provide closed loop system feedback Could not program flash (permanent) memory of MCU Project Evaluation - Shortfalls

  14. Integrate a larger screen Merge Pulse Oximeter code with control code Execute durability testing Complete software testing Reduce weight and overall size Research valuable and desired functions and features Implement self-system calibration Transfer of system data via wireless telecommunication Internal and removable memory Future Plans

  15. Unexpected risks can appear at anytime Beginning work early can allow time to discover and resolve problems Have a backup plan for all components in case of problems or failure Don’t let Dan touch anything that is critical to the system What we’ve learned
