Abstract

Un conducteur (10A) comprend une ventouse (20) et au moins une électrode (11A) fixée à la face interne de la ventouse (20) et, lorsqu'il est monté sur une surface de montage, est apte à générer une pression négative sur la face interne de la ventouse (20) sans aspiration en provenance d'un dispositif externe. La ventouse (20) comprend une section de bord circonférentiel (21) qui comporte une surface interne (21a) destinée à entrer en contact avec la surface de montage et une surface externe (21b) qui est la surface située sur la face opposée à la surface interne (21a), et qui peut se déformer élastiquement de manière à s'étendre dans la direction radiale de la ventouse (20). La surface interne (21a) et la surface externe (21b) de la section de bord circonférentiel (21) s'étendent vers le côté radialement externe de la ventouse (20) et vers l'extrémité avant (21c) de la ventouse (20) dans la direction de montage sur la surface de montage. Il est ainsi possible de fournir un conducteur qui permet de réduire les traces de conducteur restant sur une surface corporelle après le retrait du conducteur.
