Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a low-frequency therapeutic device used in an automobile, and more particularly to a device having a moxibustion effect.

(Prior Art) Conventionally, by applying an electric low-frequency pulse generated by a low-frequency pulse generation circuit to a human body from a pair of output electrodes, the human body is stimulated to treat stiff shoulders and muscle pain. A small home-use low-frequency therapy device that performs the operation is known. A low-frequency treatment device for home use is disclosed in, for example, JP-A-1-151465.
Japanese Unexamined Patent Publication No. 2-80060, a pair of conductors each having an output electrode are connected by a conductor cord to a treatment device body having a built-in low-frequency pulse generation circuit, as described in JP-A-2-80060. As described in the official gazette, there is one in which a pair of output electrodes are provided on the treatment device main body itself having a built-in low frequency pulse generation circuit. In any case, the conventional low frequency treatment device has a structure in which a battery is built in the treatment device itself as a power source for operating the low frequency pulse generation circuit. Moreover, the conventional low frequency treatment device does not have a structure for heating the output electrode.

(Problems to be solved by the invention) In a conventional low-frequency treatment device that does not have a structure for warming the output electrode as described above, the output electrode attached to the human body before use has the same temperature as the ambient temperature. Therefore, there is a problem in that when the output electrode is attached to the human body, especially when it is cold in winter, the output electrode is cold and discomfort is felt.

Therefore, it is conceivable to provide a heater adjacent to each output electrode to heat the output electrode so as to eliminate such problems and obtain a moxibustion effect in addition to the low frequency treatment effect.

However, a small-sized home-use low-frequency therapy device that is convenient to carry does not allow a large-capacity battery to be built therein. Therefore, if the heater is driven by the battery built in the treatment device main body, it is difficult to provide the heater that requires a large current because of the battery life.

The present invention is intended to solve the above-mentioned problems by limiting the use place in the automobile, and provides a low-frequency therapeutic device that can obtain a low-frequency therapeutic effect and a warm moxibustion effect without worrying about running out of batteries. The purpose is to do.
