  2. P08026 : Project Background Design a robust, replicable test-bed Simulate flow associated with Circulatory System Previous work done by Dr. Karl Schwarz of University of Rochester Medical Center

  3. P08026 : Concept Summary • Movable Membrane Drive • Bladder System • Compliance Chamber • Vascular Resistance Network • Sensor Network • LabView Interface

  4. P08026 : System Flow Loop

  5. P08026 : Design Summary • Standard 1” Vinyl Tubing • Standard 1” NPT Threaded Fittings • Teflon Tape Used at Every Threaded Opening • Hose Clamps Used at Every Junction

  6. P08026 : Design Summary Cont. Linear Actuator Actuator Interface Back-End Interface Front-End User Defined Interface One Command Allows for User Control via Buttons • Designed and Programmed for Dr. Schwarz • Runs Based Off User Generated Program and Cart Controls

  7. P08026 : Design Summary Cont. Sensors Dry/Wet Box • Pressure • Omega PX-209 • Flow • FPR-301

  8. P08026 LabView Interface DAQ USB Compatible MCC USB-1208 Sampling Rate – 40kS/s Analog Inputs

  9. P08026 : Design Summary Cont. Drive Cylinder Heart Chamber • One Way Valves Control Flow • Bag Compresses Ejecting Flow • Arm Pushes Against Membrane • Fluid Forced Out through Fitting

  10. P08026 : Design Summary Cont. Compliance Chamber Vascular Restriction 1”, ¾”, ½” Tubing Used Valves Used to Direct Flow • 2 Designs

  11. P08026 : Objective & Project Evaluation Separate Dry/Wet Components on Two Movable Carts Provide a System with Negligible Leaks Easy Draining Procedure Documentation Customized Program for Actuator Control • Pump Water Through System with Pressures Replicating 120 over 80 mmHg • Capture Initial Flow/Pressure Data • Able to Pressurize Compliance Chamber 200 mmHg

  12. P08026 : Difficulties & Future Improvements • Difficulties • Draining Was an Initial Issue • Sealing Compliance Chamber • Air Bubbles Within System • Future Improvements • Easily Customizable Control System for Actuator Control • Refinement of Drive System

  13. P08026 : Acknowledgements • Thanks to Dr. Karl Schwarz of Strong Memorial Hospital for Donation of Drive System and Other Materials • Thanks to Dr. Phillips for his Guidance • Thanks to Richard Wisniewski for Donation of Sphygmometer
