  • the two contact pads 230 can be easily attached to a portion where the body is folded or protruded, such as a joint.
  • the contact pads can be easily used in areas such as the neck, shoulders, cuffs, elbows, etc., where it is difficult to attach a conventional low frequency device in which the contact pads are fixed in a straight line, the usable range is greatly expanded.
  • a form in which a pair of contact pads 230 are provided is illustrated, but this is only an example. In some embodiments, two or more pairs of contact pads 230 may be provided.
  • the present invention can be used as a variable low frequency device used in contact with the human body.

Abstract

La présente invention concerne un dispositif à basse fréquence variable destiné à soulager les douleurs musculaires et articulaires. La présente invention peut être facilement fixée et utilisée sur des articulations ou des parties du corps courbes par changement de la position de chaque plot de contact par rapport à un générateur basse fréquence par rotation. En particulier, étant donné que de multiples plots de contact disposés dans une paire sont reliés entre eux au moyen d'un élément de feuille de liaison, les plots de contact ne sont pas facilement séparés du générateur basse fréquence lorsque les positions sont changées par rotation des plots de contact ou lorsque les plots de contact sont fixés sur le corps et utilisés.
