Abstract

L'invention concerne un équipement thérapeutique basse fréquence qui et équipé : d'une partie pastille qui est installée sur le corps d'un utilisateur, et qui amène un courant pulsé basse fréquence jusqu'à l'utilisateur ; et d'une partie corps principal qui amène le courant pulsé basse fréquence jusqu'à ladite partie pastille. Ladite partie pastille est équipée d'un seul tenant : d'une pastille exposant une couche conductrice sur au moins une partie de la première et la seconde de ses faces, et dont le côté seconde face est collé sur la peau de l'utilisateur ; et d'un support configuré pour l'installation de ladite pastille. Ladite partie corps principale est équipée : d'une partie verrouillage verrouillant ledit support ; et d'une partie électrode côté partie corps principal qui assure la conduction vers la couche conductrice exposée côté première face de ladite pastille dans un état de verrouillage dudit support sur ladite partie corps principale. Ledit support est équipé d'une partie à verrouiller qui est verrouillée à ladite partie corps principal.
