Abstract

La présente invention concerne un système de commande d'affichage d'établissement médical comprenant une unité de communication en entrée contenant une pluralité de ports d'entrée, une unité de communication en sortie comprenant une pluralité sélectionnable de ports de sortie et une unité de commande. Le port d'entrée reçoit des informations provenant d'un équipement médical fournissant des informations médicales concernant un patient et le port de sortie transmet les informations à un dispositif d'affichage. L'unité de commande communique les informations médicales entre les ports d'entrée et les ports de sortie, selon un procédé d'affichage d'informations médicales.
