When the guide 2 is applied to the surface of the human body, the suction cup 9 is deformed, the ring 12 is separated from the air inlet 15, and the valve mechanism 17 is opened. When the valve is opened, the air in the suction cup 9 is sucked into the suction part 5, and the inside of the suction cup 9 becomes a negative pressure, the deformation operation of the cup 9 proceeds, the suction cup 9 assumes a predetermined deformation state, and the electrode 6 is buffered. It is pressed against the surface of the human body via the material 23.

The cushioning member 23 deforms such as a curve along the surface of the human body. When the buffer material 23 is a hydrated body 24, the hydrated body 24 is made to contain water before use. Buffer material 23 is non-hydrated body 2
In the case of 5, a wiping process or an exchange process is appropriately performed.

Although a plurality of suction cups 9 are connected to one suction unit 5, the valve mechanism 17 of the unused suction cup 9 automatically closes, so that the unused suction cup 9 is in use. No inconvenience, such as lowering the suction action of 9, occurs.

The interfering low-frequency treatment device 1 is operated to supply two different medium-frequency currents to the electrode 6, and apply an intermediate-frequency current set to a predetermined value to the above-described two current paths to generate an interference wave current. Then, an interference stimulus is applied to the treatment site to perform treatment.

In the second embodiment of the present invention, the two-pole integral conductor 10 according to the first embodiment is replaced with a four-pole integral conductor 20.

That is, in the conductor 2 of the second embodiment, one electrode base 8 is provided with four electrodes 6, and the electrode base 8
Are housed in a flexible suction cup 9 and are treated as one conductor 2.

When a predetermined medium-frequency current is applied to the four electrodes 6, two medium-frequency currents flow in a crosswise manner at the treatment site, and an interference stimulus is applied to the treatment site.

[0039]

According to the present invention, two electrodes 6 are fixed to one electrode base 8 made of an insulating material. The electrode 6 is pressed against the surface of the human body via the cushioning material 23 by the suction deformation operation of the suction cup 9, so that the number of the conductors 2 to be mounted can be reduced to two, so that the mounting operation can be reduced. It is convenient.

Further, the number of the guides 2 to be mounted on one treatment site can be halved, and the mounting area is reduced, so that it is possible to mount on a narrow site. In addition, a narrow part is added as a mounting part of the lead 2, and the lead 2 can be easily and reliably mounted on the selected part, so that the contact state between the electrode 6 and the surface of the human body can be stabilized, which is suitable for treatment. It is convenient.

According to the present invention, four electrodes 6 are fixed to one electrode base 8 made of an insulating material, and the electrode base 8 is housed in a flexible suction cup 9 to constitute the conductor 2. Since the electrode 6 is pressed against the surface of the human body via the cushioning material 23 by the suction deformation operation of the suction cup 9, the mounting operation can be reduced because the number of the conductors 2 to be mounted may be one.
It is convenient.

Further, the number of the guides 2 to be attached to one treatment site can be one-quarter, and therefore the installation area is reduced, so that it is possible to attach to a narrow site. Further, as described above, since the lead 2 can be easily attached to the selected site and can be attached securely, the contact state between the electrode 6 and the epidermis can be stabilized, which is suitable for treatment and is convenient. In addition, although there are conventionally four places where the guide is mounted, the present invention is advantageous in that local treatment can be performed at only one place.

The guide 2 according to the present invention has a valve mechanism 17 between the electrode base 8 and the suction cup 9 for opening and closing the air passage 16 by deformation of the cup 9. When not in use, the valve mechanism 17 of the lead 2 can be closed to close the air passage 16. Therefore, the air noise generated in the air passage 16 can be suppressed, and the ability of the suction unit 5 can be reduced in order to prevent the air passage 16 from being left open, so that energy saving and noise reduction of the suction unit 5 can be reduced. It is convenient.

In the present invention, the shape of the electrode 6 is substantially half-moon-shaped. In the case of a conventional circular electrode, the contact area was reduced due to poor contact with the human body surface during suction. In contrast, the approximately half-moon electrode of the present invention has a larger diameter of the suction cup 9 while securing the electrode area and the distance between the electrodes. Can be reduced. Therefore, a large number of treatment sites can be selected by adding a narrow treatment site, and the wearability can be improved, which is advantageous.

Since the shape of the electrode 6 according to the present invention is substantially fan-shaped, the diameter of the suction cup 9 can be reduced while securing the electrode area and the distance between the electrodes, as described above. Can be selected, the wearability can be improved, and the place where the lead is mounted is conventionally four places. However, the present invention requires only one place and can reduce the size of the lead 2, so that local treatment can be performed. It is possible and convenient.

According to the present invention, since the thickness of the cushioning member 23 is set to 4 to 6 mm, the cushioning member 23 can be suitably curved along the curved human body surface, and the conduction between the electrode and the human body surface can be made good.
This is advantageous because it reduces the energization failure due to inappropriate contact of the above and improves the energization form.

According to the present invention, since the cushioning member 23 is made of a member having flexibility and lower impedance than the human body, the cushioning material 23 is interposed between the electrode 6 and the surface of the human body, and from the one electrode 6 to the human body to the other electrode. Most useful current flows to the human body by flowing most of the current to the body 6, and a wasteful current flowing directly from one electrode 6 to the other electrode 6 can be advantageously reduced.
