Abstract

La présente invention concerne un dispositif médical, par exemple une pompe à perfusion comprenant une unité de réception (I) conçue pour recevoir des données d'une commande (R), une première mémoire (RAM) qui est reliée à l'unité de réception, ainsi qu'une seconde mémoire (EEPROM) qui est reliée à l'unité de réception (I). Cette invention est caractérisée en ce que la seconde mémoire (EEPROM) est directement reliée à l'unité de réception (I). Cette invention concerne également un procédé pour contrôler le traitement correct ou l'enregistrement correct d'une valeur reçue par un dispositif médical, par exemple par la pompe à perfusion, qui est envoyée par une commande à la pompe à perfusion. Les données envoyées par la commande (R) et reçues par la pompe à perfusion (I) sont enregistrées dans une première mémoire (RAM) et dans une seconde mémoire (EEPROM), puis sont ensuite extraites de la première mémoire et de la seconde mémoire et comparées les unes aux autres et le résultat de la comparaison est renvoyé à la commande (R) par une unité d'émission (O) de la pompe à perfusion.
