DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a thermal electrotherapy device in which a heating element for heating a conductor is provided on a conductor for applying electrical stimulation to a human body.

[0002]

2. Description of the Related Art A thermal electrotherapy device in which a conductor is attached to a human body, a human body stimulating pulse is applied to electrodes of the conductor to provide a massage effect by electric stimulation, and a heating element heats the conductor. It is known from Japanese Patent Publication No. 63-26652 (A61N1 / 04). The combined use of this electric stimulation and heat simultaneously enhances the blood vessels and promotes blood circulation, so that the massage effect can be further improved.However, the stimulation is too strong, and the portion where the lead is attached becomes red, especially In the case of people with weak skin, there was a risk that the part to which the lead was attached would become rash.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and has as its object to provide a thermal electrotherapy device capable of improving safety.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a selection is made between a heating mode in which only a heating control circuit for controlling a heating element of a treatment lead and a combined mode in which a heating control circuit and a treatment current generating circuit are operated. Means is provided, and a control circuit is provided for lowering the amount of heat generated by the heating element when the combined mode is selected than when the warm mode is selected.

[0005]

When the heating mode is selected, the heating element generates heat.
In this heating mode, the heating element generates a large amount of heat, and the therapeutic lead becomes relatively high in temperature, so that a high thermal treatment effect can be obtained. When the combination mode is selected, the thermal treatment by the heat generated by the heating element and the electric treatment by the treatment current are performed at the same time, and a high therapeutic effect can be obtained due to the synergistic effect. In this combined mode, since the calorific value of the heating element is reduced, the synergistic effect between the hyperthermia treatment and the electric therapy does not become too strong.

Reference numeral 11 denotes an intensity adjustment switch for adjusting the intensity of the pulse supplied to the electrode body 4. The intensity adjustment switch 11 is provided with a treatment switch 15 to be described later, which is interlocked at an "OFF" position.
The intensity adjustment switch 11 allows the user to adjust the speed and intensity of the electric treatment as desired. When only the heat selection switch 8 is turned on, the heating mode in which the heating element 3 is energized to heat the treatment lead 1 is selected, and the treatment switch linked to the intensity adjustment switch 11 is turned on. When the operation is performed, the electric therapy mode in which a pulse is supplied to the electrode body 4 to stimulate the human body is selected, and when the switches 8 and 15 are operated, the heating of the therapeutic lead 1 and the electric therapy are performed.

That is, when the heat selection switch 8 is in the “OFF” position, no signal is output from the control circuit 13 and the heat generation control circuit 16 does not energize the heating element 3. When “ON” is selected, the heating element 3 is energized. At this time, when the treatment selection switch 7 has selected “OFF”, that is, when the heating mode has been selected, the heat generation control circuit 16 fully energizes the heating element 3 to increase the heat generation amount. When the treatment switch 15 is operated to “ON”, that is, when the combined mode is selected, the heat generation control circuit 16 controls the power supply of the heating element 3 so as to reduce the heat generation.

The output amplifying circuit 17 amplifies the pulse output from the control circuit 13 about ten times. The amplified pulse is adjusted by the output adjustment circuit 18 in accordance with the operation of the intensity adjustment switch 11, so that the treatment current flows from the electrode body 4 to the affected part of the human body. The output amplifying circuit 17 is interlocked with the therapy switch 15, and the output is gradually increased after the therapy switch 15 is turned on. The output amplification circuit 17 and an output adjustment circuit

Reference numeral 20 denotes an LED display circuit which blinks the LED 12 in synchronization with a treatment pulse supplied to the electrode body 4 when the electric treatment mode and the combined mode are selected, and until the treatment lead 1 reaches an appropriate temperature when the warm mode is selected. The LED 12 is turned on for a predetermined time and blinks after a predetermined time has elapsed.

Next, the operation will be described.

When performing a thermal treatment, or when it is desired to preheat the treatment lead 1, the heat selection switch 8 is turned on while the treatment lead 1 is mounted on a storage plate (not shown). Move to the position and select the heating mode.
In this state, since the intensity adjustment switch 11 is not operated and the treatment switch 15 is "OFF", the heat generation control circuit 16 fully energizes the heating element 3 based on the output from the control circuit 13. In this state, since the heating element 3 is fully energized, the preheating time can be reduced. When a predetermined time has elapsed, the LED display circuit 20 switches the LED 12 based on the output from the control circuit 13.
Blinks to indicate that the therapeutic lead 1 has reached an appropriate temperature. The user attaches the therapeutic lead 1 to the affected part in this state, but feels cold of the conductive pad 5 when attached to the affected part because the therapeutic lead 1 is preheated by the heating element 3. Nothing.

When performing thermal treatment, the thermal mode is maintained by keeping the thermal selection switch 8 in the "ON" position. In this state, the strength adjustment switch is
Since the medical switch 11 is not operated and the treatment switch 15 is turned off, the heating element 3 is fully energized. Therefore, the temperature of the therapeutic lead 1 becomes relatively high, and a high therapeutic effect can be obtained.

When selecting the combined mode in which the thermal treatment and the electric treatment are used together, the heat selection switch 8 is operated to the "ON" position, and the treatment selection switch 7, the speed adjustment switch 10 and the intensity adjustment switch 11 are operated. Operate as desired. In this state, since the treatment switch 15 is "ON", the heat generation of the heating element 3 is controlled by the heat generation control circuit 16 based on the output of the control circuit 13, and the heat generation amount of the heating element 3 is reduced. The treatment current is supplied to the electrode body 4 from the treatment current control circuit 19 based on the output of the control circuit 13 based on the operation of the treatment selection switch 7 and the speed adjustment switch 10 and the operation of the strength adjustment switch 11, and the muscle of the affected part is muscled. Loosen. Therefore, 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.
