Abstract

La présente invention concerne un procédé et un système permettant de contrôler des informations reçues d'un dispositif médical porté par un patient. La présente invention concerne également un dispositif médical, tel qu'un dispositif portable ou implantable, qui collecte des informations relatives au patient et des informations de fonctionnement, lesdites informations étant transmises à un emplacement central, tel qu'à un cabinet de médecin ou chez le fabricant du dispositif. Les données collectées peuvent être analysées, afin de contrôler à la fois les paramètres de santé du patient et le fonctionnement du dispositif. Une analyse des tendances peut être réalisée afin de permettre à un médecin de diagnostiquer la santé du patient et un technicien du dispositif médical peut garantir le fonctionnement correct du dispositif lui-même. De préférence une connexion modem permet d'établir une communication entre l'emplacement central et le dispositif médical et un logiciel et d'autres mises à jour peuvent automatiquement être transmis au dispositif médical lors du téléchargement de données à partir du dispositif jusqu'à l'emplacement central. Des médecins et des techniciens peuvent accéder par Internet à l'emplacement central, à partir de n'importe quel ordinateur personnel ou professionnel.
