［産業上の利用分野］
本発明は例えば人体等の患部を選択的に加熱して治療を
行なう温熱治療装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermotherapy device that selectively heats and treats an affected area of a human body, for example.
［従来技術］
ガンの治療方法には、現在、手術法、コバルト照射波、
化学的治療法、レーザー照射法、温熱治療法等がある。[Prior art] Currently, cancer treatment methods include surgery, cobalt irradiation waves,
There are chemical treatment methods, laser irradiation methods, thermotherapy methods, etc.
これらの治療法の内、温熱治療法は、ガン患部の温度を

ガン細胞のみを減少させることができるため注目されて
いる。Among these treatments, thermotherapy reduces only cancer cells without harming normal cells by increasing the temperature of the cancer affected area to a temperature higher than normal body temperature, for example around 42°5°C. It is attracting attention because of its ability to
［発明が解決しにうとプる問題点］
ところで、ガン患部の温度を上記湿度程度に高めれば、

が望まれている。しかしながら、従来の温熱治療法では
、例えば、人体の患部に高周波電界をあて、その吸収に
より患部の温度を高めているため、加熱領域を絞ること
が困難であった。[Problems that the invention is unlikely to solve] By the way, if the temperature of the cancer affected area is raised to the above humidity level,
Although it is effective in killing cancer cells, it also increases the temperature of normal tissue around the affected area, which has a negative effect on normal tissue. Therefore, it is desired to be able to selectively heat only the affected area. However, in conventional thermotherapy methods, for example, a high-frequency electric field is applied to the affected part of the human body, and the temperature of the affected part is increased by absorption of the high-frequency electric field, which makes it difficult to narrow down the heating area.
本発明は上述した点に鑑みなされた６ので、患部のみを
選択的に加熱して治療を行なうことのでさる温熱治療装
置を提供ザることを目的としている。The present invention has been developed in view of the above-mentioned points, and an object of the present invention is to provide a thermotherapy device that can perform treatment by selectively heating only the affected area.

A focal magnetic field applying means is provided, and the focal point is ! It is characterized by being configured to selectively heat the limited area by switching the heating at a certain period.

6 is continuously closed and a DC current is supplied to each induction coil, a magnetic field is formed by the three coils in the area surrounded by each iM force coil, but the combination of the magnetic fields creates a magnetic field at a certain target site. It is possible to form a so-called focal magnetic field φ whose intensity increases focally at the affected area). When this focal point El is switched on and off at a certain period Ll by the output j from the oscillator 16, a potential difference e of e=-dφ/dt [V] is generated according to Faraday's law of induction.

。Heating by turning on and off the magnetic field may be continued until the temperature of the affected area is higher than body temperature, about 42.5 degrees. Even if P is small, if it takes a long time, the absorbed power will become a large value. Fortunately, once the human body is heated, it becomes difficult to release heat to the outside, so it produces a fairly weak fever.
Even in i1, if it takes a long time, the objective will not be achieved.
