Description

  The present invention relates to a single electrode conductor type weak current treatment device used as a device for treating various pains occurring in a human body such as neck pain, back pain, and back pain.

  2. Description of the Related Art Conventionally, various low-frequency treatment devices are known in which stimulation is performed by applying a low-frequency current of about 1 mA to 50 mA at a voltage of 1 to 40 V to a diseased part of a human body from a conductive electrode. When such a low-frequency treatment device is used, human skin has a high electric resistance of about 4 kΩ, and electricity is not supplied only by bringing a dry conductive electrode into contact with the skin.

  For this reason, conventionally, for example, (1) water or conductive gel is applied to the electrode surface with a sponge, (2) the voltage is increased, or (3) an acute protrusion is provided on the electrode surface. Various treatments have been taken.

  Further, in the conventional weak current therapy, a weak current of 800 μA or less is passed through the human body, but in the case of a wet electrode, such a weak current of 800 μA has no sense of irritation and stimulation. In order to give a feeling, it is necessary to use a dry electrode.

nothing special

  However, since the treatment (1) is not effective when dried, uniform treatment results cannot be obtained, and application of water, gel, or the like is often required, and workability is lowered.

  In the treatment (2), there is a problem in that the patient's stimulation is too strong, giving a sense of fear and discomfort.

  In the above treatment (3), there is a feeling of unpleasant pain, and there is a risk that the skin may be damaged, causing an infection or the like.

  Therefore, the present invention has been devised in view of the existing circumstances as described above, and is a weakness that can increase energization efficiency, reduce irritation, and minimize the risk of infectious diseases. An object is to provide a current therapy device.

  In order to solve the above-described problems, in the present invention, a conductive single electrode body in which a surface to be contacted with an affected part of a human body is formed in a convex curved surface shape or a planar shape is provided, and a plurality of surfaces are provided on the surface of the single electrode body. The grooves are engraved in a radial or vertical / horizontal lattice pattern, and a plurality of acute or right-angled crossing outer edges formed at the crossing positions of the grooves form an energization point that alleviates electrical stimulation to the affected area. The crossing outer edge portion is formed so as not to protrude from the level of the surface of the single electrode body.

  Both the width and depth of the groove have a size of about 0.1 to 5 mm.

  A single electrode body is energized using a weak current of 800 μA or less.

  According to the present invention, it is possible to increase energization efficiency, reduce irritation, and minimize the risk of infection.

  In addition, since the crossing outer edge is formed so as not to protrude from the level of the surface of the single electrode body, the crossing outer edge does not bite into and damage the skin, and the risk of infection can be minimized. .

  And since the groove | channel has both the width | variety and depth of about 0.1-5 mm, it can fully raise the electricity supply efficiency from a cross | intersection outer edge part, and also is twice the number of the groove | channels to cross | intersect. Since an acute angle portion, that is, a crossing outer edge portion is formed, a large number of energization points can be efficiently provided on the surface of the single electrode body.

  Furthermore, since a single electrode body is energized using a weak current of 800 μA or less, the treatment effect by the weak current therapy can be sufficiently exhibited by using a dry single electrode body.

It is sectional drawing of the weak electric current treatment apparatus in the best form for implementing this invention. Similarly, an example of a single electrode body of a weak current treatment device is shown, (a) is a front view, (b) is an XX cross-sectional view of (a). It is a side view of the weak electric current treatment apparatus in another example.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  The weak current treatment device according to the present invention is a dry single electrode body 1 made of a conductive material capable of passing a weak current of 800 μA or less, for example, a conductive metal such as iron, copper, stainless steel, aluminum, etc. It is provided at the tip of the grip part 2 made of metal. This single electrode body 1 has an inner conductor 3 made of stainless steel pipe attached to the center of a plastic gripping portion 2, and the rear end of the inner conductor 3 is opened 3 a from the end of the gripping portion 2. And by connecting the plug pin 4a of the cord 4 with the plug into the opening 3a, it can be connected to a power source (not shown).

  As shown in FIG. 1, this single electrode body 1 has a smooth convex contact surface against the skin in order to prevent energization only from the peripheral portion, because the plane or only the peripheral portion strongly contacts the skin. As the curved surface, for example, a spherical surface is processed and formed, and a plurality of grooves 5 are radially engraved on the surface. Incidentally, you may form the surface of this single electrode body 1 in planar shape.

  As shown in FIG. 2 (a), the number of intersecting outer edge portions 6 that is twice the number of all intersecting grooves 5 is formed at the intersecting positions of the grooves 5, thereby An energization point that can alleviate electrical stimulation is formed.

  Further, as shown in FIG. 2 (b), the intersection outer edge portion 6 has a tip portion formed in an acute angle shape, and is substantially the same as the surface level of the single electrode body 1 or protrudes from the surface level. Not formed. The height of the front end portion of the intersecting outer edge 6 is set to be slightly lower than the contact surface level of the single electrode body 1 because the skin surface follows due to its flexibility when the single electrode body 1 contacts the skin. Is desirable.

FIG. 3 shows another example of the single electrode body 1.
In addition, the description is abbreviate | omitted by attaching | subjecting the same code | symbol to the same part as the structure in above-described form.

  That is, the single electrode body 1 is made of conductive rubber, and the contact surface with the skin is formed as a smooth flat surface, and a plurality of grooves 5 are engraved on the surface in a vertical and horizontal lattice shape.

  And at the crossing position of each groove 5, four crossing outer edge portions 6 that are twice as large as the two crossing grooves 5 are formed, thereby enabling the electrical stimulation to the affected part of the person to be eased. Is formed.

  Further, since the intersecting outer edge portion 6 has the groove 5 intersecting in a cross shape, the tip portion thereof is formed in a right angle and is substantially the same as the surface level of the single electrode body 1 or protrudes from the surface level. It is formed so that there is no.

  Further, similarly to the above-described configuration, the height of the front end portion of the intersecting outer edge portion 6 follows the flexibility of the skin surface when the single electrode body 1 comes into contact with the skin. It is desirable to set it to a slightly lower level.

  In the above-described embodiment, if the cross outer edge portion 6 for stimulating the affected area of the human body is formed on the surface of the single electrode body 1 so as not to protrude from the level of the surface of the single electrode body 1, the groove 5 The surface shape is not particularly limited. Reference numeral 4 in the figure denotes the same cord with a plug as in the above-described embodiment.

  Next, an example of use and operation of the best mode configured as described above will be described.

  In the state where the dry single electrode body 1 is pressed and brought into contact with the affected part of the human body while holding the grip portion 2, a weak current of 800 μA or less is applied to the single electrode body 1. This current is applied as an electrical stimulus to the affected area through the skin. Thereby, for example, various treatments such as neck pain, back pain, and back pain are performed.

  During this treatment, the electrical stimulation to the affected area of the person is alleviated by the energization point formed by the cross outer edge 6. Further, when the cross outer edge portion 6 is pressed against the skin surface, the cross outer edge portion 6 is formed so as not to protrude from the level of the surface of the single electrode body 1, so that the cross outer edge portion 6 bites into the skin and is damaged. There is nothing.
