SimMan Improvements Dr. Matt Weinger, MD Ray Booker Advisors: Group Members: Robert Amponsah (EECE) Bobby Gibbons (BME) Brandon Miller (BME) Evans Mize (BME) Daniel Schuler (BME/EECE)

Project Description SimMan Training simulator Mid fidelity Lacks aspects of patient response

Improvements Three areas to improve: Electric stimulation and seizure Central Line placement Lung compliance

Goals Increased realism Increased capability Improved training quality Reduced cost vs. METI implementation

Central Line Placement Two placement locations Subclavian Neck Converge to Superior Vena Cava

SimMan Design Subclavian and Neck Paths Exit through pelvis and table Collection Bucket beneath table

Materials Surgical tubing (soft) Hard plastic tubing 2 and 3 way connection joints Injection ports Blood colored fluid for veins and arteries Drainage value

Currently in the Works Determining soft tubing material Central line man simulator material Conflicting info on diameter of catheter Encasing Soft Tubing with hard tubing to prevent leakage

Chest Plate Electronics presents so it can NOT leak. Seal area off Change tubing in and out of chest plate

Electrical Cardioversion Importance 86% that receive cardioversion return to normal sinus rhythm 94% that receive medication before the cardioversion return to normal sinus rhythm Normal sinus rhythm required to be judged stable enough for surgery

Two current Plans Pneumatic Device to create necessary impulse by large air potential Costly but effective but possible size issues Usage if SimMan can be demobilized Mechanical Device using industrial strength spring and interlocked cylinder with lock and electrical release mechanism Low cost but not available in necessary size

Pneumatic Actuator Parts Tanks & Gauge Pressure Switch Relief Valve Plug Valve Pressure

Additional Items Additional Filters, Regulators, and Possibly Lubricator to maintain low ware Actuator reliant upon regulator and valves Filter Regulator

Actuator under Consideration Single Ended-Spring Return 1’’ bore at 100psi yields 314 lbs of force (πr^2) SimMan weighs ~ 50 lbs Pressure-Resistance depletes strength
