Jason Brown Mechanical EngineeringAmanda Clark Mechanical Engineering Matthew Hicks Electrical EngineeringJonathon Kelso Electrical EngineeringCharles Marion Industrial and Systems EngineeringDaniel Wisniewski Electrical Engineering
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
P08026 : Concept Summary
Movable Membrane Drive
Bladder System
Compliance Chamber
Vascular Resistance Network
Sensor Network
LabView Interface
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
P08026 : Design Summary Cont.
Linear Actuator Designed and
Programmed for Dr. Schwarz
Runs Based Off User Generated Program and Cart Controls
Actuator Interface Back-End Interface Front-End User
Defined Interface One Command Allows
for User Control via Buttons
P08026 : Design Summary Cont.
Drive Cylinder Heart Chamber Arm Pushes Against
Membrane Fluid Forced Out
through Fitting
One Way Valves Control Flow
Bag Compresses Ejecting Flow
P08026 : Design Summary Cont.
Compliance Chamber 2 Designs
Vascular Restriction 1”, ¾”, ½” Tubing
Used Valves Used to Direct
Flow
P08026 : Objective & Project Evaluation
Pump Water Through System with Pressures Replicating 120 over 80 mmHg
Capture Initial Flow/Pressure Data
Able to Pressurize Compliance Chamber 200 mmHg
Separate Dry/Wet Components on Two Movable Carts
Provide a System with Negligible Leaks
Easy Draining Procedure
Documentation Customized
Program for Actuator Control
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
