Abstract
There is disclosed an electrode construction for use in a low frequency electronic therapy device and adapted to be brought in contact with the skin at a therapy point of a human being. A negative electrode is adapted to have a contacting area between the negative electrode and the skin which is larger than that between a positive electrode and the skin. Each of the electrodes has a hollow hemispherical metal member adapted to store water in the hollow chamber. The stored water exudes little by little through perforations provided through the hollow hemispherical metal member to impregnate an outer water-impregnating cover applied to cover the hemispherical metal member.
Claims6
A low frequency electronic therapy device adapted to apply a low frequency electric stimulus to a therapy point of a warm-blooded animal which device comprises a casing, a low frequency oscillator contained in said casing, said oscillator having output terminals, at least two electrodes electrically connected to the output terminals of the oscillator, said electrodes being adapted to be brought in contact with the skin at the therapy point, each of said electrodes including a hollow hemispherical conductive member having a mouth and a plurality of perforations therethrough and a mounting metal base water-tightly fitted into the mouth of said hollow member to form a hollow chamber in said hollow member for storing water therein, each of said mounting metal bases being mounted on the outerside of said casing and electrically connected to a corresponding output terminal of said oscillator, a water-impregnating cover being applied to the outer surface of each of said conductive member covering said perforations, so that water stored in said hollow chamber exudes gradually through said perforations to impregnate said water impregnating cover, whereby said water impregnating cover is maintained impregnated with water to keep good electric contact between the electrode and the skin.
A low frequency electronic therapy device for applying a low frequency electric stimulus to a therapy point of a warm-blooded animal, which device comprises a casing;
- a low frequency oscillator located in said casing and having positive and negative output terminals;
- and a plurality of electrodes mounted on the outside of said casing adjacent to each other and adapted to be brought in contact with the skin of the animal about the therapy point, each of said electrodes being electrically connected to one of said output terminals of said oscillator, the electrodes connected to the negative output terminal through which a negative voltage is applied to the skin having a cumulative contacting area larger than that of all electrodes connected to the positive output terminal through which a positive voltage is applied to the skin.
