Title
(EN) METHODS IN A MEDICAL TELEMETRY SYSTEM
(FR) SYSTÈME de télémesure médicale
Abstract
(EN)
The invention relates to a method in a telemetry system for establishing a connection between a base station and an implantable medical device. The method comprises the steps of: starting, in the base station (4), a first timer (B-T2); determining, in the base station (4), channels that are free for communication among a number of available channels, and selecting one of the free channels; starting, in the base station (4), a second timer (B-T3); transmitting, as long as the first or second timer (B-T2), (B-T3 ) has not expired, a recognition message on the selected channel to the implantable medical device (3); and establishing, upon receipt of a recognition reply message from the implantable medical device (3), communication between the base station (4) and the implantable medical device (3) on the selected channel. The invention is readily adaptable for fulfilment of different requirements, such as stipulated by the ETSI standard.

L'invention concerne un procédé permettant d'établir une connexion entre une station de base et un dispositif médical implantable dans un système de télémesure. La procédé comprend les étapes consistant à : démarrer, dans la station de base (4), un premier compteur (B-T2) ; déterminer, dans la station de base (4), des canaux libres ouverts à la communication parmi un grand nombre de canaux disponibles et sélectionner l'un des canaux libres ; démarrer, dans la station de base (4), un second compteur (B-T3) ; transmettre, avant que le premier (B-T2) ou le second compteur (B-T3 ) n'expire, un message de reconnaissance par le canal sélectionné au dispositif médical implantable (3) et établir, sur la base d'un message de réponse du dispositif médical implantable (3) au message de reconnaissance, la communication entre la station de base (4) et le dispositif médical implantable (3) par le canal sélectionné. L'invention peut facilement être adaptée pour répondre à différentes exigences telles que stipulées par les normes ETSI.
