Description

DETAILED DESCRIPTION OF THE INVENTION The present invention detects low electrical resistance points, usually called acupuncture points, scattered on the skin, and applies a voltage to the detected low electrical resistance points to stimulate them, thereby reducing pain, etc. Concerning measuring devices.

It has long been known that electrical resistance weak points exist on the skin, and if there is a weak electrical resistance weak point on the skin where it hurts or in a specific place, the pain will be felt in the electrical resistance weak point that appears. For treatment or mitigation, one of the two electrodes is grounded and the other electrode is moved over the skin to measure the resistance between the two electrodes.

There were devices that detected weak points in resistance, applied voltage, and applied electrical stimulation to produce an effect similar to that of needles or moxibustion.

However, as mentioned above (a few seconds after applying electrical stimulation, the electrical resistance weak point moves to its vicinity, and similar electrical resistance weak points are scattered around it). In order to further improve the therapeutic effect, it is necessary to apply similar stimulation to electrical resistance weak spots scattered around the area, as well as to stimulate the electrical resistance weak spots that have been moved. To explain this in more detail, in the conventional device, one ground electrode is held in one hand, and the other electrode is moved over the skin with the other hand to generate electricity. It is necessary to detect weak resistance points, stimulate multiple electrical resistance weak points scattered around the pain area almost simultaneously, and further stimulate electrical resistance weak points that have moved after the stimulation.2" As before (one electrode, one electrode)
In the method of detecting and stimulating two weak electrical resistance points, the work efficiency is poor because the electrical resistance weak points are detected by groping, and the accuracy of detecting the electrical resistance weak points is low (sufficient effects could not be expected).

The present invention has been made in view of the above-mentioned drawbacks in order to sufficiently increase the external effect.Instead of the ground electrode and only one electrode that has been conventionally used, the present invention has been made by providing a ground electrode and a single electrode on the skin contact surface at a predetermined interval. An electrode plate having a predetermined area on which a plurality of electrodes are arranged is used, and each electrode can be selected when applying a voltage to each of the plurality of electrodes for detecting and stimulating electrical resistance weak points. By means of an energization control means equipped with a selection phase stage, the electrical resistance is detected for each individual electrode, and the voltage applied during stimulation is applied so that the stimulation is applied in accordance with the resistance value of the weak electrical resistance point. An object of the present invention is to provide a resistance measurement and voltage application device between electrodes that eliminates the drawbacks.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an electrode plate 1' having a plurality of electrodes (,
) The figure shows an approximately central portion of an insulating elastic member 1, an electrode 3 that projects roundly on the surface of the elastic member 1, and is fixed without protruding on the surface of the substrate 2, and an electrode plate 1'. a central electrode 3' penetrating the substrate 2 at a position and having a flat top and a spring 5 between the substrate 2 and the top for biasing the electrode 3' onto the surface of the substrate 2; An electrode plate 1' consisting of conductive wires 4 connected to each electrode is shown. In addition, the center electrode 3' protrudes from the surface of the elastic member 1 by pressing the top, and serves as a guide when applying the center of the electrode plate 1' to the painful area.
It is designed so that the electrode plate 1' can be accurately brought into contact with the skin.

Figure (b) shows a cross section taken along the line A-A' in Figure (&), and this state shows the state in which the electrode plate 11 is in contact with the skin, and the center electrode 3' is also connected to other electrodes. It has a protruding state similar to 3.

In addition, in contacting the skin in this state, the electrodes 3 and 3' are in close contact with the skin, so the protrusions of the electrodes 3 and 3' themselves stimulate the skin, and the contact is always constant. It also has the advantage of eliminating uncertainties in measuring the resistance value of electrically weak points caused by non-uniform contact resistance due to differences in how the skin is pressed, which occurs in the case of conventional single electrodes.

FIG. 2 shows the configuration of the electronic stimulation device according to the present invention (5). FIG.

The CPU 6 (central processing unit) that controls this device has a ROM 7 (
MPX9 (read-only memory) and RAM8 (random access memory) that can freely read and write information such as calculation results are connected, and a specific input terminal is selected from among multiple input terminals by the umbrella command of C finger PO2. A multiplexer) and an A/D converter (analog-to-digital converter) that converts the analog input selected by the MPX9 into a digital signal are connected, and the converted digital signal is read into the CPU6 as data. There is.

Further, the CPU 6 receives a signal from an operation number designating switch SWI for inputting the number of times a predetermined operation is to be repeated, and a signal from a start switch SW2.

In addition, the output signal method from the CPU 6 estimates the number of operating errors
A display 11 that displays the number of times SXW 1 has been pressed
The smallest resistance value among the weak electrical resistance points is detected (6) and input to the B display 12 indicating the position of the electrode 3 and the buzzer 13 indicating the operation of the device. In addition, CPU
The output from the power source 6 is configured to send a signal to an F/V converter 4 (frequency-voltage converter) and an output power switch 15, which constitute a power supply section, respectively.

To explain this power supply section in detail, the F/V converter 4 outputs a voltage according to the input frequency, and the CP
The command from U6 is given as a frequency, and a desired voltage is output from the F/V converter 14 in accordance with the command.

Further, the output power switch 15 is a switch that turns off the output having a predetermined voltage from the F/V converter 14 according to a command from the CPU 6.
The power supply section consisting of the V converter 4 and the output power switch 15 is designed to freely obtain an output (square wave output) having a voltage and frequency based on commands from the CPU 6. In addition, the part surrounded by the broken line in the figure shows the selected tooth membrane, and the selection stage includes a decoder 16 for decoding the code signal from the CPU 6 and the decoder 16.
This is a selection stage consisting of an analog switch 17 that opens and closes according to the output of It seems like he is being guided. When the decoder 16 is used in this way, it is especially advantageous if the number of electrodes is large (if the number of electrodes is large), and the analog switch 16 is
Of course, 7 may be replaced by other means such as a relay.

Next, the F/V converter 14 and the output power switch 11 are controlled by a command from the CPU 6, which explains the flow of current.
The power from the power supply section consisting of 5 is routed along the route indicated by the arrow.

First, the current output from the power supply section is guided through the decoder 16 and the output terminal of the analog switch 17, which is in a closed state, to the electrodes 3 and 3' corresponding to the output terminal according to a command from the CPU 6. Glue the skin from electrodes 3 and 3' and enter the ground electrode G.

This ground electrode G is a resistor R having a known predetermined resistance value.
It is coupled to the ground of the power supply section via.

Also, the current flows from the connection between the ground electrode G and the resistor R to M
It is led to the input terminal of the PX 9, and the output from the power supply section is also led to the other input terminal of the MPX 9.

This MPX9 receives each of the above inputs by commands from the CPU6.
/ Supplied to the D converter 10.

Also, the reason why the power supply output is directly connected to one terminal of MPX9 is to feed back the output voltage from the power supply unit, and the output voltage from the power supply unit is read and output from the CPU 6 to F
This is to correct the frequency supplied to the /V converter 14 and adjust it to a predetermined voltage.

The voltage read through the first ground electric device G is input to the other terminal of the MPX 9, and by measuring this voltage, the resistance of the human body can be obtained by calculation. This calculation is performed as follows.

First, the output voltage (hereinafter referred to as V port) from the power supply section is fed back as described above and stored in RAM8 (9) and remains at a known level.This output voltage drops as it passes through the skin, and this drop voltage is applied to the resistor R. In other words, if the resistance of the skin is r, this is equivalent to applying a known voltage V to a circuit in which a resistor r and a known resistor R are connected in series.

Here, if the voltage Vr after passing through the skin resistance r is measured as described above, r can be found. The voltage Vr is read into the CPU 6 via the A/D converter 10 and stored in the RAM 8. Expressing this in a formula, since this circuit is a series circuit, the currents flowing through resistors r and R are equal, so V
r/R is the current flowing through each resistor, and Vr/R=
From V-Vr/r, r=R(v-Vr)/Vr
Since Vr, R, and V are all known values, the value of skin resistance r can be obtained.

Next, the operation of the present invention will be explained according to the operation flow shown in FIG. First, the main switch of this device is turned on.

In the next step 1 (hereinafter referred to as S1), the number of times set by the operation number specifying switch SWI is read and stored, and this data is stored in the RAM 8.

In S2, the number of inputs is displayed on the A display 11K, for example, if N times have been input, N is displayed.

In S3, it is determined whether the start switch 8W2 is ON or OFF, and if the determination is YES, the process proceeds to the next step 84; if NO, the process waits until the start switch 8W2 is pressed.

In S4, a number obtained by subtracting the number set in 821, which will be described later, from N shown on the person display 11 is displayed, indicating that the operation has started. S5 is a step in which the buzzer 13 is sounded in a predetermined manner to notify the user with a sound.

In S6, a predetermined frequency from the CPU 6 is input to the F/V converter 14, and a voltage is output in accordance with the input. At this time, the output voltage of this predetermined frequency is increased step by step according to the value stored in the ROM 7, and the output voltage is from v0 to v1 (V is the maximum value applied when detecting weak electrical resistance points). Voltage) occurs up to volts. At this time, the output power switch 15 is in the ON state.

S7 inputs the voltage directly input to MPX9 from the power supply section to A.
/ This is a step of reading into the CPU 6 via the D converter 10.

In S8, the operation of the selection means is performed in response to a command from the CPU 6, and the analog switch 1 is operated via the decoder 16.
7 is opened or closed, a specific electric power is applied, and the voltage Vr corresponding to each electrode 3 and 3' is stored at an address corresponding to each electrode in the RAM 5, respectively.

In S9, the read Vr at each electrode is read out from the RAM 8, and the resistance value r is calculated according to the above-mentioned formula.

In 810, the resistance values calculated in S9 are arranged in ascending order of magnitude. This means that the weak electrical resistance points (sizes of pots) are arranged in descending order of resistance values.

At 811, it is determined whether or not the number of electrodes whose resistance is infinite among the plurality of electrodes as a result of the operations from 86 to S9 is equal to or greater than a predetermined number. In this step, the contact of the electrode plate 1' with the skin is inappropriate, or in other words, the way it is pressed against the skin is inappropriate.
This is to detect the number of electrodes that are not in contact with the skin. If there is a predetermined number or more of infinite resistance values, the answer is YES and the process proceeds to 812.

At step 812, it is determined whether the applied voltage when the answer at step 811 is YES is a predetermined upper limit voltage V or not. If the upper limit voltage V,
If it is below, the result is No, and the process returns to S6, and the voltage is increased in accordance with the increasing frequency, step by step, which is stored in advance in the ROM 7, and S6 to Sit are repeated until the applied voltage reaches the upper limit voltage V+.

This means that when measuring skin resistance, conditions vary depending on perspiration and the measurement site, and it is not possible to adequately measure the skin resistance value with a constant applied voltage at normal pressure. This is to ensure that the resistance value of the skin can be measured without being influenced by the weather.

The reason why the upper limit voltage v1 is provided is that weak electrical resistance points that are not detected even when the upper limit voltage V is applied are not considered to be acupoints. If the determination in 812 is YES,
It is assumed that the contact of the electrode plate 1' with the skin is completely inappropriate or that the electrical resistance weak point is strong, and in S13 the buzzer is
It rings in a different way than the one that sounded at 5, and at 814 A.
The display on the display 11 is set to 0 and the process returns to Sl.

Next, return to 811 and if it is determined No at 811, 81
Proceed to step 5.

815 and below represent the operation of energizing the plurality of electrodes 3 and 3' to provide stimulation.

When applying stimulation, applying stimulation according to the detected electrical resistance weak point is the key to increasing the therapeutic effect.
In other words, it is the cycle of strength and weakness of stimulation. As an embodiment of the present invention, the strength and weakness of the stimulation is determined by the magnitude and cycle of the voltage output from the F/V converter 14 depending on the frequency from the CPU 6 input to the F/V converter 14.
This is obtained by a combination of cycles in which the output power switch 15 is opened and closed according to commands from the CPU 6.

815 is the input to the F/V converter 14 (1
4) This is to determine the frequency from the CPU 6, which is searched from the MAP in which the frequencies shown in FIG. 4(a) are stored. Search from the MAP is performed by a well-known method, and it goes without saying that values other than the grid points of the MAP are interpolated using a four-point interpolation method or the like.

The X-axis direction of the MAP in FIG. This is the resistance value of the weak resistance point. The value searched based on these two parameters is the frequency given from the CPU 6 to the F/V converter 14, and this frequency is designated as f.

In this way, the respective frequencies f for the plurality of electrodes 3 and 3' are determined, and the frequencies f corresponding to each electrode are stored in the RAM.
8 is stored.

816, the X axis is f, and the Y axis is the output power switch 1.
A table is shown in which the period of opening and closing of 5 (this is referred to as fV) is shown, and the 0N-OFF period of the output power switch 15 corresponding to each electrode is determined according to f determined in 815, and similarly to 815. It is stored in RAM8. It goes without saying that the same interpolation calculation as in S15 is performed in this step as well.

The X-axis in Figure 4 (,) shows the applied voltages from V to -V when measuring weak electrical resistance points, and the Y-axis shows the resistance values r0 to -V.
It shows up to fcts and also sets up to fMIN - fMAX (not written). (b) In the figure, the X axis is f
MIN~fMaX is shown, and the Y axis shows fvMIN """
IyMaX is shown.

At step 817, the output voltage from the F/V converter 14 and the output power switch 15 are opened and closed based on the values derived at steps 815 and 816, and an output having a predetermined voltage and cycle is generated from the power supply section. I am forced to do it.

81 via the decoder 16' under the command of the CPU 6 so that the
9, which of the electrodes determined in S11 are valid;
In other words, it is determined whether or not a voltage has been sequentially applied to all the electrodes whose measured resistance value did not become infinite. If No, the process returns to 818 and voltage is applied to all the effective number of electrodes. YB
If it is 2, proceed to 820.

In 820, as mentioned above (after applying stimulation to the electrical resistance weak point, the distribution changes, so the time, e.g.

For example, wait 2 to 3 seconds.

At 821, the step is set to 0 at the start of the operation.

This operation means that the repeat operation read in S1 has been completed once.

At 822, it is determined whether the number of operations read in Sl has been performed a specified number of times, and if NO, the process returns to s4 and repeats up to 821 as described above.

At 823, the position of the weak electrical resistance point having the minimum resistance value (17) calculated at 89 in the last operation of the specified number of times from S4 to 821 is displayed on the B display 12.

This display method may include, for example, causing LEDs (light emitting diodes) arranged at positions corresponding to each of the plurality of electrodes to emit light, or indicating the coordinates of the electrodes using numbers.

This display indicates the next movement position of the electrode plate 1'.In other words, it indicates the liquid level and position of the center electrode 3' of the electrode plate 1' that is most effective for the next operation from 81. Pointy.

Step 824 causes the buzzer 13 to sound in a manner different from that used in steps S5 and 813 to notify that the designated operation has been completed.

In S25, the display of the ANN container 11 is set to 0 to notify that the operation has ended, and the operation ends.

As explained above, according to the present invention, an electrode plate having a plurality of electrodes is used, weak electrical resistance points are measured on each side of the electrodes, and optimal stimulation can be applied according to the measured resistance. It is possible to obtain significant effects compared to conventional equipment.

In this example, the number of electrodes is (18) Although the case is 5, the same applies even if the number is further increased.

It goes without saying that the method of detecting weak electrical resistance points and controlling the stimulation voltage application of the present device disclosed in the above detailed description may be applied to a conventional device having one electrode.
