Title
(EN) MEDICAL DEVICE WITH POWER-UP ROUTINE
(FR) DISPOSITIF MÉDICAL À PROGRAMME DE MISE SOUS TENSION
Abstract
(EN)
The present invention is directed towards a method for powering up a medical device (1) powered by a battery (2). The method includes executing an initial battery test. In the initial battery test, a difference voltage between a battery voltage measured without and with a test load is determined. The test load is favourable dimensioned not to significantly stress the battery. The difference voltage is compared with a difference voltage threshold, the difference voltage threshold being predefined in dependence of the no-test-load voltage. The method further includes providing an alarm if the difference voltage is above the difference voltage threshold. The invention further concerns a medical device that implements the before-mentioned method and a method for determining the relation between the difference voltage and the difference voltage threshold. The invention may be used to ensure that an alarm is provided if a newly inserted battery is too weak to power the medical device for the complete powering-up.
(FR)
La présente invention concerne un procédé de mise sous tension d'un dispositif médical (1) alimenté par une batterie (2). Le procédé consiste à exécuter un test initial de batterie. Lors du test initial de batterie, une tension de différence entre une tension de batterie mesurée sans charge de test et une tension de batterie mesurée avec une charge de test est déterminée. La charge de test a une dimension favorable pour ne pas solliciter de façon importante la batterie. La tension de différence est comparée à un seuil de tension de différence, le seuil de tension de différence étant prédéfini en fonction de la tension de test sans charge. Le procédé consiste en outre à émettre une alarme si la tension de différence dépasse le seuil de tension de différence. L'invention concerne en outre un dispositif médical qui met en œuvre le procédé mentionné ci-dessus et un procédé de détermination de la relation entre la tension de différence et le seuil de tension de différence. L'invention peut servir à garantir l'émission d'une alarme si une batterie nouvellement insérée est trop faible pour alimenter le dispositif médical pour la mise sous tension complète.
