Therefore, the temperature is controlled to such a degree that a burn is not caused even if it is adhered to the affected part for a long time.

When the electric therapy mode is selected,
The heat selection switch 8 is operated to the "OFF" position, and the treatment selection switch 7, the speed adjustment switch 10, and the intensity adjustment switch 11

Operate as desired. In this state, since the temperature of the therapeutic lead 1 decreases, the synergistic effect between the thermal treatment and the electric treatment does not become too strong, and a high therapeutic effect can be obtained.

In this embodiment, the guide 1 is attached to the mounting portion.
Although the duty of the heating element 3 is controlled based on the output from the detection sensor 15 when the heating element 3 is detached, the power supply to the heating element 3 may be cut off.

[0023]

As described above, according to the first aspect of the present invention, when the conductor is preheated, the power supply to the heating element of the conductor is cut off or reduced when the conductor is removed from the mounting portion. In addition, when the guide is attached to the affected part, the risk of causing a burn or the like can be eliminated, and the amount of heat generated during preheating can be increased to shorten the preheating time.

According to the configuration of the second aspect of the present invention, the power supply to the heating element of the conductor is reduced when the conductor is removed from the mounting portion at the time of preheating of the conductor. In this case, it is possible to eliminate the danger of causing a burn or the like, and to increase the amount of heat generated during preheating to shorten the preheating time.
