DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to adjustment of voltage and time applied to a potential therapy device, and to a thermal / potential therapy device.

[0002]

2. Description of the Related Art Potential treatment devices for general households are legally regulated for the potential application time. Among them, those having a function of switching the potential voltage are used to change the application time depending on the applied voltage. It is necessary to keep the voltage ratio constant. In a conventional controller having a potential voltage switching function, a counter is provided for each set voltage.
The product of each counter value and the applied voltage is obtained by an arithmetic element such as a microcomputer, and the sum is compared with a value previously stored in the microcomputer to obtain a certain therapeutic effect.

[0003] Further, the electric potential therapeutic device and the hyperthermic therapeutic device are separated,
Each is used individually for therapeutic purposes.

[0004]

[Problems of the prior art] Even in the calculation by a calculation element such as a microcomputer, obtaining the product of the application time and the applied voltage increases the program capacity. In some cases, unless a microcomputer having a function exceeding the purpose of use is selected. Instead, the cost burden increased.

[0005] In the case of performing both the electric potential treatment and the hyperthermia treatment, one of the treatments is performed and then the other is performed, so that it takes too much time to give the patient pain, and the treatment effect becomes individual. I can not expect much.

[0006]

SUMMARY OF THE INVENTION The present invention has been developed to solve these drawbacks. The present invention provides a low-cost treatment instrument having a function equivalent to that of the prior art using a microcomputer having a simple function. A combination of hyperthermia and electric potential treatment to enhance the therapeutic effect, and even if the duration of the hyperthermia treatment occurs, provide a safe and secure treatment by keeping the intensity of electric potential voltage and treatment time constant, Within, it seeks to achieve both therapeutic goals.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described with reference to FIG.
In the potential therapy device 1 that can be switched between two ways, V, the maximum application time corresponding to each applied voltage is 8 hours,
Assume time. Counter for counting application time-2
Assuming that the unit time is 1 second, 28800 counts are performed to count 8 hours, and 14400 counts are performed in the case of 4 hours, so that the set time can be calculated.

In the above analogy, the applied voltage is −300 V
At 8 hours, at -600V the application time is 1 /
Since the count is twice as long as 4 hours, the count number is set to 14400 based on -600 V, and when -300 V is set, the unit time is set to 2 seconds, which is twice as long as the counter -2.
Is set to be the same in any setting.

When the electric potential therapy device 1 and the thermal treatment device 3 are combined, as shown in FIGS. 2, 3 and 4, the electric potential treatment conductor 4 of the electric potential treatment device 1 and the heat treatment induction device in the thermal treatment device 3 are used. A heating element (a heating element or a planar heating element) 6 is bonded via a surface sensor 5 so that the voltage of the potential therapy device 1 can be applied only during the off-time period of the thermal therapy in the thermal therapy device 3.・ Electric potential therapy is performed.

The electric potential treatment lead 4 and the surface sensor 5 have a structure in which carbon is applied to the inner surface of a vinyl chloride film.
The potential therapy lead 4 applies a negative potential voltage, and the surface sensor 5 is a potential insulation film made of vinyl chloride which covers the thermal therapy lead 6 when a needle, a nail or the like is stabbed or by local heating. The controller 8 senses when the device 7 is destroyed and stops the power supply by the controller 8.

When the power supply circuit 9 is turned on by the operation switch, the thermal treatment conductor 6 is heated, and the impedance is decreased by the rise of the temperature, and the controller 8 controls the temperature by the change. There is a load control circuit 1
Numeral 1 controls the supply of electricity to the thermotherapy lead 6 in response to a change in the temperature sensor 10 so as to maintain a desired temperature.

[0012] After the temperature of the load control circuit 11 is turned off after exceeding the set temperature in this way, the voltage selected by the potential setting switch 12 is applied to the potential treatment lead 4. If the temperature of the temperature sensor 10 becomes lower than the set differential temperature during the application of the electric potential, the application of the electric potential is stopped, and the energization of the thermal treatment conductor 4 is started. Alternating application of heat and potential is repeated, and when the maximum time of the potential application time has elapsed, the potential voltage is not applied even when the thermotherapy device 1 is turned off. Each treatment does not interfere.

In the figure, reference numeral 13 denotes a heat adjusting lamp which is turned on only during heat treatment. 14 is a control circuit.

[0014]

As described above, when the applied voltage is -300 V, the applied time is 8 hours, and when the applied voltage is -600 V, the applied time is 1/2 times, that is, 4 hours.
In the case of setting -300V with reference to 400, the value counted by the counter-2 is the same in any setting by setting the unit time to twice 2 seconds, and the counter is separately set by the set voltage. Even if the applied voltage is switched during treatment by monitoring only one counter value without preparing or changing the number of counts according to the set voltage, the applied voltage and the applied time can be controlled.
The same control as the method of obtaining and controlling the total product can be obtained, and the program capacity can be reduced because it does not calculate the sum of products by the arithmetic elements. And the size of the microcomputer itself can be reduced, and the occupancy of the PC board in the product can be reduced to provide a less expensive product.

In the case of alternately energizing the thermal treatment and the electric potential treatment, the power supply may be turned on after setting the intensity of the temperature and adjusting the potential voltage. Since the currents are alternately applied, the therapeutic effect can be synergistically enhanced by the mutual treatment means, and the respective treatments do not interfere with each other, so that they are safe and can be provided at low cost.

The potential treatment time is integrated even if the off-time during the thermal treatment varies depending on the difference between the temperature of the hyperthermia treatment and the outside air temperature. Time is always kept constant,
It is safe because there is no need to apply too much potential treatment.
