BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermotherapy device, and more particularly to a high-frequency thermotherapy device which prevents a patient from being burned by an inadvertent movement during treatment.

[0002]

2. Description of the Related Art In the conventional high-frequency thermotherapy device of this type, a pair of output terminals are provided on the main body of the high-frequency generator, and conductors are provided on the pair of output terminals. And
One conductor electrode is provided inside each of the pair of conductors. The pair of conductor electrodes are formed so that their polarities are different from each other, and a frequency of several MHz to several tens of MH is set in a space which faces each other.
Form a high frequency charging magnetic field of z. Then, when the pair of mite is pinched on an affected area such as neuralgia from above the skin or clothes,

In the conventional high-frequency hyperthermia device, when one conductor is held by hand to adjust the mounting state of the conductor during operation, electromagnetic waves propagate to the other hand and the other hand is held. Trying to reach the Michiko no Miko. At this time, when the point is brought into point contact with any part of the body, the electromagnetic wave tries to reach the other conductor through the point contact part, so that the energy of the high frequency thermotherapy device is focused at the point contact part. There is a risk of causing burns. Since it is possible for a patient to perform such an operation at the time of treatment frequently, this poses a serious safety problem.

Therefore, there arises a technical problem to be solved in order to prevent the patient from being easily burned during use and to improve the safety of the high-frequency thermotherapy device. The object is to solve the problem.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been proposed in order to solve the above problems, in which a high frequency generating means is provided with a conductor and a conductor electrode is internally provided in the conductor. In the hyperthermia treatment device, one conductor has a plurality of conductor electrodes provided therein, and at least one of the plurality of conductor electrodes has a polarity different from that of another conductor electrode. The present invention provides a thermotherapy device that is formed to have a different polarity.

[0006]

In the high-frequency hyperthermia device according to the present invention,
A plurality of conductor electrodes are arranged in one conductor,
Since the polarity of at least one of the plurality of conductor electrodes is different from the polarity of the other conductor electrodes,
The electromagnetic waves emitted from any one of the conductor electrodes of the individual conductors are focused on any of the other conductor electrodes provided in the same conductor. That is, when the conductor is gripped by a hand to adjust the wearing state of the conductor, an electromagnetic wave that diverges from any of the conductor electrodes in the gripped conductor and flows into the inside of the hand from one part of the palm. Will flow out of the other part of the palm and converge on any other conductor electrode in the gripped conductor. Therefore, even if the hand holding the conductor is brought into contact with any part of the body, the electromagnetic wave does not propagate from the hand to any part, and the energy is focused at the contact point. There is no risk of burns. Thus, the safety of the high frequency thermotherapy device is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 shows a configuration diagram of a high-frequency thermotherapy device 1, in which an output of a high-frequency generator 2 formed by a high-frequency oscillation circuit or the like is transmitted to a matching circuit 4 via a balun 3. The matching circuit 4 is for matching the output impedance Z _O with the load impedance of the affected area, and the capacitance of the variable capacitor incorporated in the matching circuit 4 so that the load current I flowing through the matching circuit 4 is maximized. Is automatically controlled.

An output cord 5 consisting of two conductors 5a and 5b having mutually different polarities is extended from the matching circuit 4, and the output cord 5 (conductors 5a and 5b) extends in two directions on the way. The conductors 6 and 7 are disposed at the ends of the branches. Each of the conductors 6 and 7 has a pair of conductor electrodes 8, 9 and 10, 11 inside a skin made of an insulating cloth. The conductor electrode 8 of the conductor 6 and the conductor electrode of the conductor 7 are provided. 10 is connected to the conductors 5a and 5a having one polarity, and the conductor electrode 9 of the conductor 6 and the conductor electrode 11 of the conductor 7 are connected to the conductors 5b and 5b having the other polarity, respectively. ing.

Thus, as shown in FIG. 2, a pair of conductor electrodes 8 and 9 internally provided in one conductor 6 or 7.
(Or 10, 11) shows different polarities at a frequency of several MHz to several tens of MHz, and the conductor electrodes 8, 9 (or 10, 11) in the same conductor 6 (or 7) respectively A high-frequency charging magnetic field is formed as a starting point or an ending point. Then, when the guides 6 and 7 are attached to the affected area, the high-frequency charging magnetic field acts on the affected area to cure heat.

FIG. 3 shows a state of the electromagnetic field when the hand 12 is brought into contact with the upper surface of the conductor 6 (or 7). As shown in the figure, since both the starting point and the ending point (the conductor electrodes 8, 9 or 10, 11) of the electromagnetic field formed above the conductor 6 (or 7) are directly under the hand 12, the electromagnetic field is generated by the hand 12. It is stored inside and hardly leaks outside. Therefore, even if the fingertips of the hand 12 or the back of the hand 12 touches other parts of the body in this state, electromagnetic waves will not flow into the other parts through the contact parts as in the conventional case. That is, when the patient holds his / her hand on the upper surfaces of the conductors 6 and 7 for adjusting the wearing condition of the conductors 6 and 7 during treatment, the hand is held on other parts of the body. Even if the point contact is made, energy is not focused on the point contact portion, and therefore there is no risk of burns. Thus, the safety of the high frequency thermotherapy device is improved.

It should be noted that the number of conductor electrodes provided inside one conductor is 2
The number of electrodes is not limited to one, and two or more, and at least one of them may have a polarity different from that of another conductor electrode. For example, three conductor electrodes may be internally provided in one conductor, and each conductor may be formed so that the phase difference between them is 120 °. Moreover, the number of conductors is not limited to two, and may be one or three or more.

Therefore, the present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention covers the modifications.

[0013]

As described in detail in the above-mentioned one embodiment, the present invention is one in which a plurality of conductor electrodes are internally provided in one conductor.
The electromagnetic waves diverging from each conductor are formed so as to converge on the conductor. Therefore, when the patient holds the conductor with his / her hand to adjust the wearing state of the conductor during treatment, even if the hand comes in contact with any part of the body, the electromagnetic field is applied from the inside of the body to the body. Since it does not leak to any part of the above, the energy is not focused on the contact part to cause burns as in the conventional case. Thus, the safety of the high frequency thermotherapy device is improved.
