Abstract

La présente invention concerne des générateurs d'ultrasons équipés d'affichages graphiques, d'interfaces contrôlées par l'opérateur et d'une communication avec des instruments utilisés avec lesdits générateurs. Un dispositif d'identification par radiofréquence ou un lecteur de code-barres peut être utilisé pour communiquer au générateur d'ultrasons un signal d'identification provenant d'une pointe. Une mémoire associée au générateur d'ultrasons stocke une pluralité de profils de fonctionnement, chacun étant corrélé à un unique signal d'identification, chaque signal d'identification correspondant à une pointe particulière reçue dans une pièce à main associée au générateur d'ultrasons. L'information concernant les pointes particulières, notamment la durée de vie restante de la pointe, la température au niveau de la pointe, la pression exercée par la pointe, le numéro de lot, le numéro de pièce, le numéro de série et la date de fabrication de la pointe peut être affichée sur un écran prévu sur le générateur. Un dispositif de commande modifie le profil de fonctionnement de la pointe correspondant au signal d'identification associé à la pointe reçue dans la pièce à main lors de l'occurrence de conditions prédéterminées.
