[0001]

[Industrial applications]

 The present invention relates to an electric hyperthermia treatment device that can be used by being integrally attached to the skin.

[0002]

[Prior Art]

 The term "heat and heat" used in the present invention includes moxibustion and moxibustion, and an electric thermotherapy device that can be used by sticking it on the skin has to use a small capacity battery such as a button type or coin type. Absent.

[0003]

[Problems to be Solved by the Invention]

 The battery must supply a large current to the heating element in order to heat the living body at about 70 ° C. However, the battery that can satisfy this requirement has a drawback that it becomes larger. On the other hand, although a mode in which a secondary battery is repeatedly used has been proposed, gas is accumulated in the battery because the charging time is long and if the battery is rapidly charged, overcharging tends to occur. It had a defect that it was easily deteriorated.

[Means for Solving the Problems]

 In view of the above, the present invention realizes a compact thermotherapy device that eliminates the above-mentioned dangers and shortens the charging time by using the charge storage means instead of the battery. The charge storage means is, for example, a capacitor, and a supercapacitor of about 1 (F) or the like is used. Recently, a button-type supercapacitor with a diameter of about 20 (mm) and a thickness of about 5 (mm) that is small and lightweight and has a capacity of 1 (F) or more is commercially available. Such a capacitor is preferably used in the present invention. The capacitance value, size, shape and the like are appropriately selected and used. In addition, the present invention may be equipped with a plurality of charge storage means and may be operated simultaneously or sequentially.
