Title
(DE) MEDIZINISCHE ELEKTRODENVORRICHTUNG
(EN) MEDICAL ELECTRODE DEVICE

Abstract
(DE)
Es wird vorgeschlagen eine Elektrodenvorrichtung (30) zum Messen von elektrischen Signalen (53, 61), insbesondere von elektrischen Signalen eines lebenden Körpers (12) wie EEG-Signalen, mit einem Gehäuse (40), an dem eine Elektrode (46) aus einem elektrisch leitfähigen Material so festgelegt ist, dass die Elektrode (46) mit einer Messoberfläche (44) in Kontakt gebracht werden kann. Dabei ist eine zweite Elektrode (54) vorgesehen, die an dem Gehäuse (40) festgelegt und gegenüber der ersten Elektrode (46) elektrisch isoliert ist, wobei die zweite Elektrode (54) mit der Messoberfläche (44) nicht in Kontakt kommt.
(EN)
The invention proposes an electrode device (30) for measuring electrical signals (53, 61), in particular electrical signals from a living body (12), such as EEG signals, said device having a housing (40) to which an electrode (46) of an electrically conductive material is secured in such a manner that the electrode (46) can be brought into contact with a measurement surface (44). In this case, provision is made of a second electrode (54) which is secured to the housing (40) and is electrically insulated from the first electrode (46), wherein the second electrode (54) does not come into contact with the measurement surface (44).
(FR)
La présente invention concerne un dispositif d'électrodes (30) servant à mesurer des signaux électriques (53, 61), en particulier les signaux électriques d'un corps vivant (12) comme les signaux EEG, avec un boîtier (40) auquel est fixée une électrode (46) en matériau électriquement conducteur de telle sorte que l'électrode (46) est mise en contact avec une surface de mesure (44). Selon l'invention, il est également prévu une seconde électrode (54) qui est fixée au boîtier (40) et est électriquement isolée de la première électrode (46), la seconde électrode (54) n'entrant pas en contact avec la surface de mesure (44).
