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
