Abstract

L'invention porte sur un système de triage électronique par lequel des informations sur des changements d'état de personnes blessées et malades et des conditions médicales peuvent être obtenues de manière consécutive, et dans lequel ledit système peut être partagé parmi le personnel médical. Le système de triage électronique (10) peut construire un réseau ad hoc N avec des étiquettes de triage électroniques (20), des terminaux à utilisation par le personnel médical (30), des stations de base (40), et un serveur (50) en tant que nœuds. Les étiquettes de triage électroniques (20) peuvent obtenir, émettre et recevoir des informations biométriques de personnes blessées et malades, émettre et recevoir des données pour estimer des emplacements de celles-ci. Le serveur (50) stocke des informations biométriques reçues et peut émettre des informations à des terminaux à utilisation par le personnel médical (30). Le serveur (50) peut estimer des emplacements relatifs entre des personnes blessées et malades auxquelles des étiquettes de triage électroniques (20) ont été attachées et un personnel médical portant les terminaux à utilisation par le personnel médical (30), et émettre des données d'estimation d'emplacement (LD) présentant les résultats aux terminaux à utilisation par le personnel médical (30). Les terminaux à utilisation par le personnel médical (30), sur la base des données reçues à partir du serveur (50), peuvent afficher des conditions de changement d'état et des positions relatives des personnes blessées et malades.
