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

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

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

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

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

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

8. 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

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

10. 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

11. 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

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

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

14. 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
