A device for safely relieving pain in a human or animal includes a pair of pads for placing against a body at spaced apart locations, e.g. on the front and back of an abdomen for treating back pain. One of the pads has an electrically conductive layer, e.g. aluminum foil for placing against the body where treatment is required, and the other pad includes an electrically conductive core sandwiched between insulating layers. The electrically conductive layer and the core are connected to the electrodes of a dry cell or other source of direct current, whereby a direct current is caused to flow between the body and the electrically conducting layer.
L'invention concerne un dispositif qui permet de soulager en toute sécurité la douleur chez les humains ou les animaux. Le dispositif comprend une paire de coussinets à placer à des points espacés sur le corps, p. ex. sur l'avant et l'arrière de l'abdomen pour traiter un mal de dos. Un des coussinets est muni d'une couche conductrice d'électricité, p.ex. du papier d'aluminium à placer sur le corps lorsqu'un traitement est requis, et l'autre coussinet comprend un noyau conducteur d'électricité disposé entre des couches isolantes. La couche et le noyau conducteurs d'électricité sont liés aux électrodes d'une pile sèche ou à une autre source de courant continu, ce qui amène le courant continu à circuler entre le corps et la couche conductrice d'électricité.
