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

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

  3. SimMan Design • Arterial and Venous Lines • Subclavian and Neck Paths • Exit through pelvis and table • Collection Bucket beneath table

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

  5. Design Parameters • 60 cc of liquid in system • Venous System • 2.5 meters of tubing • 50cm soft tubing for needle insertion, 150cm hard tubing for casing of liquid in system • Arterial System • 75cm soft tubing

  6. Joints and Injection Ports • Joints connect the soft to hard tubing • Catheter must be able to pass • Catheter block port must allow fluid flow • Injection ports located behind head

  7. Goals of Electrocardioversion • Create a device that will simulate a human’s reaction to electrocardioversion. • Imitate a simulate a tonic-clonic seizure. • Decide how to activate the device. • Choosing the most economical and accurate device.

  8. Response for Electrical Cardioversion • Observation of current systems…METI • Ideas and Drawbacks being considered • Spring-loaded mechanism • Resetting spring, lack of multiple levels, size • Air compression release mechanism • Sound of air release, time for compressor • Hydraulic Systems • Size, cost, maintenance

  9. Seizure Response • Observation of current systems…METI • Ideas and Drawbacks being considered • Massage Devices • Too weak, quality=expensive • Novelty Items • Weird, weak, quality=expensive, • Professional riveting devices • Expensive, size, heavy • Others

  10. Current Implementations http://www.meti.com/Product_HPS.html • Current top-of-the-line is constructed by Medical Education Technology, INC (METI) • Do have a convulsive physical response (“chills”) • Difficult to locate METI’s implementation

  11. Current Implementations • Movement accomplished through a servo, which rotates the “universal joint,” rotating the thumb (and hence the hand) about the longitudinal axis of the arm. S.
