Development of defibrillation simulator with LC-Tank type inductance coupling position measurement system

Abstract

In this study, we construct a paddle positioning system for defibrillation training simulators. The system consists of a chest manikin fabricated based on the standard somatotype of Koreans and simulator paddles similar to those of commercial defibrillators. Multiple coils are arranged orthogonally in both the chest manikin and paddles; their positioning is based on electromagnetic induction, such that the positions of the paddles can be successfully detected across the chest. The calculated and actual positions are compared using the measured signals. We find a mean error of 0.0891 mm for all positions, with a standard deviation of 0.6611 mm. In addition, we connect our paddle positioning system to a graphical user interface that enables visualization of the paddles’ current locations.
