2. Description of the Related Art In this type of treatment apparatus, a plurality of electrodes are attached to an affected area to be treated, and a treatment current (pulsating direct current, etc.) is passed between the electrodes to treat muscle fatigue and the like. A pulsed pulsating DC current is generally used as the treatment current, but the pulse frequency of the treatment current used for treatment depends on the condition of the affected area to be treated, for example, the degree of muscle fatigue, the degree of muscle pain, or whether it is acute or chronic. And the amplitude value will be different.

[0003]

Conventionally, the frequency and magnitude of the treatment current having a great therapeutic effect have been determined by the therapist based on his experience and intuition by observing the state of the affected area. In addition, when there are a number of affected parts to be treated, it is also determined based on experience and intuition which part should be intensively treated to improve the therapeutic effect.

1 to CH4. The conductor detachably connected to these output terminals has an adsorbing rubber at the tip for adsorbing and fixing it to the affected part, and an electrode electrically contacting the affected part is embedded on the adsorbing surface side of this adsorbing rubber. It is configured to connect the electrode and the output terminal with a covered conductor.

It is turned on every 5 seconds and then energized. The reason for inverting the polarity of the pulsating direct current in this way is to prevent the electric charge from accumulating in the affected part and causing pain to the patient if the current is applied in only one direction.

The operation of the apparatus of this embodiment will be described below. First, the output mode which is a method of supplying the treatment current to the eight conductors will be described. In the apparatus of this embodiment, there are three output modes, namely, "fixed mode", "scan mode", and "multi-scan mode". Hereinafter, these modes will be described in order.

[Fixed Mode] FIG. 6 is a diagram for explaining a combination of conductor pairs used in the fixed mode. As shown, the conductors T1 and T2 of channel CH1, channel CH2
Conductors T3 and T4 of the channel CH3, and conductors T5 and T6 of the channel CH3,
For each of these four conductor pairs, a pair of conductors (hereinafter referred to as a conductor pair) of the conductors T7 and T8 of the channel CH4 is defined (therefore, the maximum number of conductor pairs in fixed mode is four). The treatment current is applied simultaneously and independently. The constant current amplifier for supplying the treatment current to each channel is determined by turning on / off each switch of the matrix circuit 2. In this embodiment, channels CH1, CH
Constant current amplifiers S1, S2, S3, and S4 independently apply a treatment current between the conductors of CH2, CH3, and CH4. The magnitude of the treatment current is set to about 10 μA to 900 μA (set in consideration of the size of the surface area of the conductor and the sensitivity on the skin, usually 100 μA to 400 μA, and the same will be described later).

[Scan Mode] FIG. 7 is a diagram showing an output conductor table for explaining the scan mode and the multi-scan mode. The numbers in parentheses shown in FIG. 7 are combination numbers between the conductors, for example, (1) represents the combination of the conductors T1 and T2, and (10) represents the combination of the conductors T2 and T5.

FIG. 1 is a view for explaining a combination mode of conductors used in the scan mode. As shown in FIG. 1, in scan mode, one of the eight conductors is defined as a reference conductor, and a conductor pair is provided between the reference conductor and each of the remaining seven conductors. The conductor pair is set, and the treatment current is applied to the pair of conductors by sequentially shifting the time. The attachment position of the reference electrode is, for example, a portion where the muscle bundles converge while intersecting when treating the pectoralis major muscle, or a base of the Achilles tendon when treating the Achilles tendon.

In this can mode, only one constant current amplifier is used. In this embodiment, the constant current amplifier S is used.
Energize at 1. That is, by constantly turning on the switch on the output terminal a side of the constant current amplifier S1 and sequentially turning on one of the seven switches connected to the output terminal b side, the above seven conductor pairs are connected. The treatment current is sequentially applied to. In this scan mode, the magnitude of the treatment current is set to about 10 μA to 40 μA, and the pair switching cycle is set to about 15 sec.

[Multi-scan Mode] FIG. 8 is a view for explaining a combination mode of the conductors used in the multi-scan mode. In this multi-scan mode, there is no concept of a channel, and electricity is conducted between the conductors that can be conducted. There are 28 combinations of conductors that can be a conductor pair as shown in FIG. 7, but when the number of conductors is 8, two conductors forming a pair do not overlap with other pairs. Since the number of conductor pairs that can be formed at the same time is 4, 28 conductor pairs are divided into 7 groups of 4 conductor pairs, and 4 conductor pairs are included for each of the 4 conductor pairs in one group. Current amplifiers S1 to S
In step 4, the treatment current is independently supplied, and the treatment current is sequentially applied to the seven groups at different times. In this multi-scan mode, the magnitude of the treatment current is 10 μA-9
The switching cycle of the conductor pair group is set to about 15 sec.

FIG. 9 is a table for deciding the order of energizing the groups of four conductor pairs that can be assembled at the same time. The encircled numbers are indicated by circled numbers in the figure. FIG. 10 shows in detail the relationship between the combination number and the energization sequence of FIG. As can be seen from these figures, in the first order, the conductors T1 and T2, T3 and T
4, T5 and T6 and T7 and T8 are energized by constant current amplifiers S1, S2, S3 and S4, respectively. In the following order, constant current amplifiers S1, S2, S4, S3 are provided between the conductors T1 and T3, T2 and T4, T5 and T7, T6 and T8, respectively.
Energize with. In the same manner, the four conductor pairs of the group are simultaneously energized in the same order. 11 to 17, the positions of the switches of the matrix circuit 2 that are turned on in each order of the multi-scan mode are indicated by the circles.

The above description of the multi-scan mode is for the case where the number of conductors mounted is 7 or 8, but multi-scan can be performed even when the number of conductors is less than this. For example, FIG. 18 is a table for determining the order in which the groups of conductor pairs that can be assembled at the same time are energized when the number of conductors mounted is 5 or 6. The encircled numbers are indicated by circled numbers in the figure.
In this case, the number of constant current amplifiers used is three at a time in each order. Similarly, FIG. 19 is a table for determining the order in which the groups of conductor pairs that can be assembled at the same time are energized when the number of conductors mounted is 3 or 4, and the constant current used in this case is used. In each order, the number of amplifiers is two at a time.

Next, a method of detecting whether or not the conductor is mounted will be described. In this embodiment, it is possible to judge whether the conductor is mounted, unmounted or not mounted but poorly mounted (electrical contact failure of electrodes). This determination is performed based on the measurement result obtained by measuring the conductivity (= conductivity) σ between the conductors. This measuring method will be described below.

First, the table shown in FIG. 9 is used as a conductor search order table. That is, the conductivity between the four conductor pairs is measured at one time, and this measurement is performed in seven times.
The conductivity of the conductor pair is measured by an automatic search. Thus, the four constant current amplifiers S1 to S4 can be simultaneously used to efficiently measure the conductivity between the conductors. Turning on / off of the switch of the matrix circuit 2 in each of the measurement orders 1 to 3 is as shown in FIGS.

The search current used for the automatic search is direct current, and the magnitude of the current (amplitude value) is 10 μA. The current magnitude is reduced to 10 μA so that the automatic search can be performed without stimulating the patient. Control unit 10 to 10 μ for each constant current amplifier S1 to S4
It is instructed to pass the current of A, and the output voltage value of each constant current amplifier S1 to S4 at the time of energization is A / D converter 17.
To detect each. The conductivity σ of each conductor pair connected to the constant current amplifiers S1 to S4 is obtained by the following formula: conductivity = output voltage value / current value (= 10 μA) of each constant current amplifier S1 to S4 [unit: SIEMENS]. Based on this measurement,
When the conductivity is 10 ^-6 [SIEMENS] or less, it is determined that both or one of the conductors of the conductor pair is not mounted or is improperly mounted. It is possible to specify which conductor is not mounted or improperly mounted by outputting the measurement results for all the conductor pairs according to the conductor search order table.

The conductor retrieval result is displayed on the liquid crystal display 16 in the form as shown in FIG. 20, for example. In this display example, the conductivity is color-coded in five stages according to its height and displayed. That is, from the highest conductivity to 0-10 ^-2 , 1
0 ^-2 to 10 ^-3 , 10 ^-3 to 10 ^-4 , 10 ^-4 to 10 ^-5 , 10
^-5 to 10 ^-6 . The reference conductor is one of the eight conductors T1 to T8. The standard conductor can be selected by using a conductor with a smaller number as the standard conductor.
Here, the conductor T1 of the channel CH1 is used as a reference conductor.
The color display of each conductor is changed according to the degree of conductivity between the respective conductors as viewed from the reference conductor T1. In other words, a square box is provided for each conductor, and the circle is marked at the center of the square to show the conductor. A circle is further provided outside the circle, and the area between the outer circle and the square frame is shown. Color according to conductivity. If the conductor is not mounted or is poorly mounted (conductivity is 10 ⁻⁵ or less), no outer circle is provided. In other words, the color of 10 ^-5 to 10 ^-6 and the inner color of the outer circle are the same, so the outer circle cannot be seen. The example of FIG. 20 shows that the conductor T2 of the channel CH1 and the conductor T3 of the channel CH2 are unmounted or poorly mounted.

By looking at the display of such a conductor search result, the user can immediately determine which conductor is unmounted or improperly mounted. In some cases, it is possible to immediately take measures such as remounting the guide, so that it is possible to prevent the treatment from being started without mounting or poorly mounting the guide necessary for the treatment.

Further, even when the treatment device is used without connecting electrodes to all the output terminals to which the electrodes are connected (8 in this embodiment), regarding the output terminals which have been found not to be mounted by the above method, In order to prevent the supply of therapeutic current through the output terminal in each of the above-mentioned output modes, in other words, to form a conductor pair with only the mounted conductors and to conduct the therapeutic current, It can be controlled by 10.

Next, a treatment mode for treating the affected area using the apparatus of this embodiment will be described. In this treatment mode, the optimum frequency (pulse pulsation frequency) and amplitude value of the treatment current in the above-mentioned three output modes (fixed, scan, multi-scan) are automatically determined, and "multi-scan mode" In (1), the affected area requiring treatment is automatically searched and the treatment is intensively performed on the affected area. Hereinafter, the treatment mode in each output mode will be described.

[Fixed Mode] (a) Number of Conductors Used There are four conductor pairs used for treatment in the fixed mode, as shown in FIG. 6, and treatment currents are simultaneously applied to the four conductor pairs.

(B) Frequency band exploration treatment The current value of the treatment current is 100 μA and the frequency is 1 Hz.
, 30 Hz, and 200 Hz, and the treatment current of each frequency is output to each inter-conductor pair for 5 seconds in this order. A hold circuit for monitoring the output voltage of the constant current amplifiers S1 to S4 is provided, the hold circuit is reset 1.5 seconds after the start of the therapeutic current output of each frequency, and the output voltage of the constant current amplifier is measured 2 seconds later. Hold again, reset again after 4.5 seconds, re-measure after 5 seconds and hold. The conductivity σ at each time point is calculated from each measured value, and the rate of change Δσ is calculated from the conductivity at each time point. This calculation is done for all the conductor pairs used. The frequency band and the current value to be used in the next sequence frequency site scanning treatment are determined according to the order of the rate of change in conductivity with the frequency shown below.

[Large to Small Conductivity Change Rate by Frequency] Conductivity Change Rate Frequency Band (Set Current Value) (Small) (Medium) (Large) 1, 30, 200 Hz P3 (100 μA) 1, 200, 30 Hz P2 (200 μA) 30, 200, 1 Hz P2 (200 μA) 30, 1, 200 Hz P2 (200 μA) 200, 1, 30 Hz P2 (200 μA) 200, 30, 1 Hz P1 (400 μA)

There are three types of frequency bands, P1, P2, and P3, and each frequency band P1, P2, and P3 is composed of eight frequencies as shown below. P1 (for acute) treatment frequency band 100, 120, 140, 160, 200, 240, 2
80,320Hz P2 (general pain) treatment frequency band 10,15,20,30,50,70,100,120
Treatment frequency band of Hz P3 (for muscle fatigue) 0.3, 0.5, 0.7, 1, 3, 5, 7,
10Hz

(C) Frequency site scanning treatment With respect to the frequency band determined by the frequency band search treatment, a treatment current is applied for 5 seconds each from the lower one of the eight types of frequencies in the frequency band. The current value of the treatment current is P
When the value is 1, 400 μA, when P2 is 200 μA, and when P3 is 100 μA. At the same time, a treatment current of each frequency is applied, and then the rate of change in conductivity at each frequency (8 types) is measured by the same method as that obtained by the frequency exploration treatment. Then, among the eight types of frequencies used, three types of frequencies are selected from the one having the largest conductivity change rate. Do this for each pair of conductors.

(D) Intensive treatment The three types of frequencies selected in the frequency site scanning treatment are applied for 15 seconds in order from the lower frequency at the current value specified in the previous section, and this is repeated twice. This operation is performed for each conductor pair.

(E) Concentrated after-treatment 1 at a frequency and waveform of 0.5 Hz and a current value of 100 μA
Energize for 5 seconds, switch the waveform to the (-) side polarity, and energize for another 15 seconds.

(F) Overall aftertreatment In the combination of all the conductors used (28 pairs of conductors in the multi-scan mode), each conductor is treated under the condition of the mode used in the concentrated aftertreatment. Energize for 5 seconds each. Even for waveforms with switched polarities, power is applied for 5 seconds each.

[Scan Mode] (a) Number of Conductors Used There are seven conductor pairs used for treatment in the scan mode as shown in FIG. 1, and the treatment current is temporally different for the seven conductor pairs. Shift and energize sequentially.

The following (b) frequency band exploration treatment, (c) frequency region scanning treatment, (d) intensive treatment, (e) intensive aftertreatment, and (f) overall aftertreatment are performed in the same manner as in the fixed mode. However, in the scan mode, the intensive treatment of (d) terminates energization by the three types of frequencies selected in the frequency region scanning treatment in one loop.

[Multi-scan Mode] (a) Number of Conductors Used There are 28 conductor pairs used for treatment in the multi-scan mode, as shown in FIG. On the other hand, each group is sequentially energized with a time shift.

(B) Frequency band exploration treatment The same algorithm as in the fixed mode is used. However, there are 28 conductor pairs, and a treatment current is applied to each of these conductor pairs by using three kinds of frequencies (1, 30, 200 Hz).

(C) Frequency site scanning treatment With respect to the frequency band determined by the frequency exploration treatment, a predetermined waveform and current value are applied for 5 seconds each from the lower frequency of the eight types of frequencies in the frequency band. There are 28 conductor pairs to be energized. At the same time, as in the case of the frequency region scanning treatment in the fixed mode, the conductivity change rate Δσ is obtained, and three types of frequencies are selected from the larger conductivity change rate Δσ.

Based on the measurement results, as shown in FIG. 21, the conductivity change rate Δσ is determined for each of the _{three selected} frequencies f ₁ , f ₂ and f ₃ having a large conductivity change rate Δσ.
2 pairs of high-conductivity conductors (conductance pairs such as change rates Δσ ₁ , Δσ ₂ ...) are arranged in order from the highest one, and 4 groups each with 4 highest conductivity change rate at each frequency. Choose. Therefore, a total of six conductor pair groups are selected at three frequencies. However, the same conductor can be used in two sets of the same frequency.
No more than one may be included, and if so, the derivative pair is ignored. The six conductor pair groups thus selected (24 pairs in total) will be used in the next intensive care.

(D) Intensive treatment Of the six conductor pair groups obtained by the above frequency site scanning treatment, the four conductor pairs (of the lowest frequency f ₁ having the highest rate of change in conductivity) ( A treatment current of frequency f ₁ is simultaneously applied to the conductor pair group having the change rates Δσ _{1 to} Δσ ₄ ) for 15 seconds. The current value is a value determined by the mode (P1 to P3) obtained by the frequency band exploration treatment.

Next, the same operation as described above is performed for the second lowest frequency f ₂ . The frequency of the treatment current in this case is f ₂ . When this is completed, the same operation as above is performed for the _third lowest frequency f3. The frequency of the treatment current in this case is f ₃ . After that, the same frequency as above is applied to the four conductor pairs (the conductor pair group having the change rates Δσ _{5 to} Δσ ₈ ) having the second highest conductivity change rate by returning to the lowest frequency f ₁ . This is also performed for frequencies f ₂ and f ₃ . Repeat this operation loop twice

(E) After-treatment of frequency part A current of 100 μA at a frequency of 0.5 Hz is applied for 15 seconds in the order of intensive treatment (4 pairs × 6 sets). After that, the polarity of the current waveform is switched to the (−) side, and the current is similarly supplied.

(F) Overall aftertreatment A current is applied in the same manner as in the fixed mode (up to 28 pairs x 2).
Times)

Various modifications are possible in carrying out the present invention. For example, in the above-described embodiment, three types of frequencies (1, 30,
Although the treatment frequency band is determined based on the conductivity change rate using 200 Hz), the present invention is not limited to this. It is possible to determine the treatment frequency band more precisely.

Further, in the present embodiment, the treatment frequency band is further divided into eight types of frequencies, and a more appropriate frequency is selected from them, but of course this is not restrictive.
One type of frequency may be associated with the treatment frequency band, and when the treatment frequency band is determined, the corresponding frequency may be immediately used as the treatment frequency.

Further, in the present embodiment, it was only in the multi-scan mode that the affected area having a high conductivity change rate was extracted and concentrated on that area, but the present invention is not limited to this. Alternatively, in the fixed mode or the scan mode, the affected area having a high conductivity change rate may be concentrated.
