Development of the ECG Detector by Easy Contact for Helping Efficient Rescue Operation

Abstract

When a large-scale disaster occurred, it is expected that much damage occurs. In recent years, various rescue robots are developed as second anti-disaster measures mainly. The realization of a quick rescue operation is expected by these rescue robots. To save life of more victims, it is important that rescuers divide a victim by triage. Effective rescue operations can be realized by it. However, well trained person for the triage can do correct judgment, but it is difficult for other people. Therefore, if rescuers gather bio-signals of the victim when they find or save the victim, they can get a clear criterion. From this, it is thought that many rescuers can evaluate the condition of the victim correctly using bio-signals of the victim. So, we developed the device to detect an electrocardiogram by easy contact in this study. The electrocardiogram is one of the important vital signs in the bio-signal of the human. If we can detect an electrocardiogram, we can diagnose the change of the condition of the person. At the time of the disaster, the diagnosis of the irregular pulse is effective in particular. It is possible to diagnose the irregular pulse by only one detected electrocardiogram. However, the measurement of electrocardiogram at the time of the disaster is difficult, because 12 lead electrocardiogram which is the most general method needs ten electrodes. Therefore we avoid the method to need many electrodes in this way, we aimed for the detection of the electrocardiogram with as few electrodes as possible to be able to measure it at the stricken area. In addition, for the realization of a more effective measurement, I aim at the development of the induction method that is able to detect a electrocardiogram by electrodes which do not touch skin directly.
