When there are a lot of injured people at a large-scale disaster site, medical staff first do triage. Triage is to decide the priority for treatment depending on the degree of severity or urgency of injured people. Paper triage tags are used now to show their condition and to record information on injuries. We do research that collect information of injured people by using electronic triage tags which replace the current paper tags. To do prompt and accurate emergency medical services with electronic tags at a disaster site, it is important for medical staff to engage in a disaster-relief training using them on a daily basis. So we propose the disaster-relief training system using the electronic triage tag. This system supports to develop the scenarios of injured people information and transport information. We let the electronic triage tag generate vital signs of injured people constantly. By collecting and monitoring those data at regular intervals, we aim to conduct a more practical disaster-relief training considering the change in symptoms of injured people.
