Description

  The present invention relates to a waveform generator for a biostimulation signal that effectively performs muscle training, relaxation, shape-up, muscle pain treatment, fatigue recovery, and the like by applying electrical stimulation to the living body.

  It is well known that electrical stimulation is applied to muscles by bringing electrodes (conductors, pads) into contact with the surface of the body and applying electrical pulse waves and sine waves, resulting in muscle activation and relaxation effects. Waveform generators for biostimulation signals have been put to practical use as devices and health appliances.

  Conventionally, this type of waveform generator for electrical biostimulation is performed by applying a low-frequency treatment signal between a pair of electrodes mounted on a patient's body surface. Furthermore, a multi-channel waveform generator has also been proposed that can provide a sense of tracing the patient's body surface with a hand with an appropriate force and a sense of "rotation".

  For example, Patent Document 1 describes a waveform generator having a mode in which outputs from a plurality of output units (output control units) are sequentially performed with a time shift.

JP 2003-245363 A

  In the waveform generation device described in Patent Document 1, outputs from a plurality of output units are sequentially performed while shifting the time from each other, and one output unit requires a pair, that is, two electrodes, At least four electrodes are required for the output section.

  Furthermore, paragraph 0040 describes that the number of output units is preferably 3 or more, particularly 4 or more as shown in the embodiment, in order to obtain a sufficient “feeling of rotation”. In the group, eight electrodes are required, and there is a problem that connection mistakes at the time of treatment and entanglement of the lead wire are likely to occur, and cleaning up of the electrodes after treatment becomes complicated.

  The present invention solves such a conventional problem, and only two output units (output control units) and three electrodes can provide a sense of “rotation” and other treatments. It is an object of the present invention to provide a waveform generator that is unlikely to cause connection mistakes and entanglement of lead wires and that can easily clean up electrodes after treatment.

  The waveform generator of the present invention includes a first electrode, a second electrode, and a third electrode that are arranged at positions of apexes of arbitrary triangles on the surface of a living body, a high-frequency portion having a first time width, and a second time width. An intermittent wave generating means for continuously outputting an intermittent wave constituting one cycle with a pause portion having a predetermined low frequency period; and a two-phase signal for oscillating first and second ultra-low frequency signals having the same frequency Oscillating means, first output control means for modulating the amplitude of the intermittent wave output from the intermittent wave generating means with the first ultra-low frequency signal and outputting it between the first electrode and the second electrode, and the intermittent wave generating means output And a second output control means for modulating the amplitude of the intermittent wave with the second ultra-low frequency signal and outputting it between the first electrode and the third electrode, the first ultra-low frequency signal, and the second ultra-low frequency A configuration in which signals are in a predetermined phase relationship and electrical stimulation is given to the living body That.

  According to the present invention, it is possible to obtain a sensation of “rotating scissors”, “upper fir tree”, and “left and right fir tree” with only two output control units and three electrodes without changing the position of the electrodes. Thus, it is possible to provide a waveform generator that is unlikely to cause an electrode connection mistake or entanglement of the lead wire, and that can easily clean up the electrodes after treatment.

  Next, the “rotation rubbing” effect will be described.

  On the waveform selection operation panel 7, for example, the menu selection “inner training”, on the phase mode setting operation panel 8, the menu “rotation”, and for example, “speed: 2” on the scale of “speed” 1 to 10 When the value is set to dial and the waveform intensity setting operation panel 9 is set to a value of “strength: 30” on the scale of “strength” 0 to 30, for example, the CPU 1 satisfies the predetermined setting conditions. Based on this, the continuous wave oscillating unit 2 is controlled by the instruction value 101, and a continuous high frequency with a pulse frequency f 1 of 600 kHz, for example, is oscillated and output to the intermittent wave converting unit 3.

CPU1, to the intermittent wave conversion unit 3, and controlled by the indication value 102, for example, change the range continuous frequency f1 from the first time width 103 50μ seconds 400μ seconds in the third ultra-low frequency 20Hz , frequency f2 as an intermittent wave 106 having a low frequency cycle 105 to change the range of 10kHz from 1kHz fourth ultra-low frequency 5 Hz, and outputs the first output control unit 5 and the second output control section 6.

The state where the first time width 103 and the frequency f2 are periodically changed is not shown. The third may be ultra-low frequency and fourth ultra-low frequency asynchronous be out of sync, even without change in the third ultra low frequency or fourth ultra-low frequency, a fixed Also good.

Third varying the ultra-low frequency or fourth ultra-low frequency can change a stimulus to a living body, it is possible to increase the inner training and relaxation.

  The CPU 1 sets 1 Hz as the frequency value 151 of the first and second very low frequency signals f3 to the two-phase signal oscillating unit 4 based on the selection / setting values and the program setting values from the operation panels 7, 8 and 9. The phase of the polarity value 116 and the amplitude value 117 of the second ultra-low frequency signal output to the 2-output control unit 6 is set to the polarity 111 and the amplitude value 112 of the first ultra-low frequency signal output to the first output control unit 5. For example, 40 V is output as the delay of 120 degrees with respect to the phase and the maximum value 153 of the amplitude value 112 and the amplitude value 117 corresponding to the value of “strength: 30”.

  When the two-phase signal oscillated by the two-phase signal oscillating unit 4 is expressed as Asin (θ) for the first output control unit 5 and Asin (θ + φ) for the second output unit 6, φ = −120 degrees. Can show. “A” is the maximum amplitude value 153.

  The two-phase signal oscillating unit 4 has a timing for each period of the first output wave 113 defined by the polarity value 111 and the amplitude value 112 of the first very low frequency signal, and the polarity value 116 of the second very low frequency signal. And a timing for each cycle of the second output wave 118 defined by the amplitude value 117 and the timing signal 154 are output to the CPU 1.

  That is, the two-phase signal oscillating unit 4 notifies the CPU 1 of the timing that is an integral multiple of θ = 360 degrees and the timing that is an integral multiple of θ + φ = 360 degrees, and maintains synchronization between the two-phase signals.

  Based on Asin (θ), the two-phase signal oscillating unit 4 supplies the first output control unit 5 with the polarity value 111 of the first very low frequency signal shown in FIG. 3b and the amplitude value of the first very low frequency signal shown in FIG. 112, and based on Asin (θ + φ), the second output control unit 6 outputs the polarity value 117 of the second very low frequency signal shown in FIG. 3f and the amplitude value 117 of the second very low frequency signal shown in FIG. Is output.

  The first output control unit 5 changes the intermittent wave 106 shown in FIG. 3a with the polarity value 111 of the first very low frequency signal shown in FIG. 3b, and the first very low frequency signal shown in FIG. The waveform shown in FIG. 3 e is output as the first output wave 113 between the first electrode 11 and the second electrode 12.

  The second output control unit 6 changes the intermittent wave 106 shown in FIG. 3a with the polarity value 116 of the second ultra-low frequency signal shown in FIG. 3f to the second ultra-low frequency signal shown in FIG. 3h. The waveform shown in FIG. 3 i is output as the second output wave 118 between the first electrode 11 and the third electrode 13.

  As shown in FIG. 4a, the realization of “rotation scrubbing” will be described in the case where the first electrode 11, the second electrode 12, and the third electrode 13 are arranged at the respective vertexes of the triangle. Note that each voltage vector P1, P2, P3 ', P3 in FIG. 4 represents only a vector, that is, a direction and a magnitude, and does not indicate a reference position for voltage application.

  The first output wave 113 is applied as a voltage represented by a vector P1 in the direction from the first electrode 11 to the second electrode 12, and as shown in FIG. 4c, the phase angle d1 is delayed by 60 degrees from the reference point. In this case, the second output wave 118 is applied as a voltage represented by a vector P2 in the direction from the third electrode 13 to the first electrode 11 at a phase angle d2 that is 120 degrees out of phase from the vector P1.

  Since the combined vector (P1 + P2) of the vector P1 and the vector P2 is applied with the voltage represented by the vector P3 ′ in the direction from the third electrode 13 to the second electrode 12 as shown by the broken line in FIG. A voltage represented by a vector P3 of − (P1 + P2) is applied from the second electrode 12 to the third electrode 13.

  That is, as shown in FIG. 4c, the vector P3 serves as a power source having a phase angle d3 that is further delayed by 120 degrees from the vector P2, and the effect of “rotation” can be realized.

  Depending on the positional relationship among the first electrode 11, the second electrode 12, and the third electrode 13, whether it feels right rotation or left rotation changes.

  Further, even if the positional relationship among the first electrode 11, the second electrode 12, and the third electrode 13 is the same, the second output wave 118 is delayed by 120 degrees from the first output wave 113, or the first output wave Depending on whether the second output wave 118 has a phase advanced by 120 degrees from 113, it is possible to switch between “right rotation thrust” and “left rotation thrust”.

  The phase lag or phase advance (φ) of the second output wave 118 with respect to the first output wave 113 does not have to be strictly ± 120 degrees, and may be approximately ± 120 degrees to produce the effect of “rotating”. . Further, depending on the shape of the triangle formed at the positions of the first electrode 11, the second electrode 12, and the third electrode 13, the rotational speed of the “rotation scissors” may be uniform or non-uniform.

  By changing the frequency value 151 on the phase mode setting operation panel 8, the rotation speed of the “rotation scrub” can be changed. When the frequency value 151 is set to about 0.05 Hz, a slow “rotation rub” effect can be obtained.

  When the frequency value 151 is increased, the rotation speed of the “rotation brushing” effect becomes faster, and when the frequency is increased to about 10 Hz, it becomes possible to obtain the “surface polishing” effect in which the “rotation brushing” is continued at a high speed. . The frequency value 151 may be set continuously variable or may be set stepwise.

Moreover, the frequency conversion value of the low frequency period 105 of the intermittent wave 106 is set to 1 kHz to 10 kHz based on the fact that this frequency range can feel various changes in bodily sensations.

  Moreover, the high frequency can use the arbitrary frequencies whose pulse frequency f1 is 10 kHz to 650 kHz. It is generally said that a higher frequency penetrates deep inside the living body. It is also said that the higher the frequency, the less the tingling sensation on the surface of the living body, and the frequency may be selected according to the purpose.

The lower limit of 10 kHz is based on setting the upper limit of the frequency conversion value of the low frequency period 105 of the intermittent wave 106 to 10 kHz.

  In addition, the upper limit is set to 650 kHz. In order to make it easy for the operator of the waveform generator to perform lead wire processing, three electrode lead wires are bundled three-dimensionally or planarly from the waveform generator main body. This is because the effect of signal attenuation or the like becomes prominent due to the stray capacitor in the bundled portion when the frequency is higher than 650 kHz.

  If three lead wires are separated from each other without being bundled from the main body of the waveform generator, it can be implemented up to about 1 MHz.

  Further, although the case where the menu “inner training” is selected on the waveform selection operation panel 7 is described, it goes without saying that other menus such as “relaxation” may be set.

  Next, the “upper and lower fir” effect and the “left and right fir” effect will be described. As shown in FIG. 1, the following “upper and lower fir” and “left and right fir” are as follows: the first electrode 11 is the upper vertex of the triangle, the second electrode 12 is the lower left vertex of the triangle, and the third electrode 13 is the lower right vertex of the triangle. The case will be described. Needless to say, if the positional relationship between the first electrode 11, the second electrode 12, and the third electrode 13 is changed, the positional relationship such as "upper and lower" and "left and right" changes relatively.

  The settings of the waveform selection operation panel 7 and the waveform intensity setting operation panel 9 do not need to be changed in particular from the “rotation thrust”. When the “up / down” menu is selected on the phase mode setting operation panel 8, the CPU 1 determines the two-phase signal oscillating unit 4 based on the selection / setting values and the program setting values from the operation panels 7, 8 and 9. On the other hand, only the phase relationship 152 between the first output wave 113 and the second output wave 118 is changed.

  The CPU 1 sets the phase 152 for the two-phase signal oscillating unit 4 and the polarity value 116 of the second very low frequency signal in phase with the polarity value 111 in the first cycle, that is, φ = 0 degrees. Then, the timing signal 154 is output to the CPU 1 at the end of the first cycle.

  In the second cycle, the CPU 1 changes the phase 152 with respect to the two-phase signal oscillating unit 4 and the polarity value 116 of the second very low frequency signal is opposite to the polarity value 111, that is, φ = 180 degrees. A timing signal 154 is output to the CPU 1 at the end of the second cycle.

  In the third cycle, the CPU 1 returns to φ = 0 degrees. As described above, φ is alternately changed between 0 degree and 180 degrees for each cycle of the second very low frequency signal.

  The two-phase signal oscillating unit 4 is connected to the first output control unit 5 based on Asin (θ) as shown in FIG. 5b and the polarity value 111 of the first very low frequency signal shown in FIG. Based on Asin (θ + φ), the second output control unit 6 outputs the second ultra-low frequency signal polarity value 117 shown in FIG. 5d and the second ultra-low frequency signal shown in FIG. 5e. The amplitude value 117 of the very low frequency signal is output.

  The first output control unit 5 changes the intermittent wave 106 shown in FIG. 5a by the polarity value 111 of the first very low frequency signal shown in FIG. 5b, generates a waveform similar to FIG. 3c (not shown), and FIG. 3 is output as a first output wave 113 between the first electrode 11 and the second electrode 12 (not shown).

  The second output controller 6 changes the intermittent wave 106 shown in FIG. 5a with the polarity value 116 of the second very low frequency signal shown in FIG. 5d to generate a waveform similar to FIG. 3c (not shown), and FIG. A waveform similar to that shown in FIG. 3 e is output as a second output wave 118 between the first electrode 11 and the third electrode 13 (not shown).

  When the polarity value 111 shown in FIG. 5b and the polarity value 116 shown in FIG. 5d are in phase, that is, when the phase values in FIG. 5f and FIG. 5g are in phase, p1 and when the polarity value 111 and polarity value 116 are in reverse phase, That is, when p2 is the case where FIG. 5f and FIG. 5g are in the opposite phase, only the second electrode 12 and the third electrode 13 are felt in the in-phase p1, and only the first electrode 11 is felt in the opposite-phase p2. By repeating p1 and p2 alternately, the “upper and lower fringing” effect can be realized.

  When the frequency value 151 is set to about 0.05 Hz, a slow “up and down fringing” effect can be obtained. When the frequency value 151 is increased, the vertical movement speed of the “upper and lower fir” effect becomes faster, and when the frequency is increased to about 10 Hz, the feeling of “up and down fir” cannot be obtained.

  Next, “left and right fir tree” will be described. There is no particular need to change the settings of the waveform selection operation panel 7 and the waveform intensity setting operation panel 9. When the “left / right” menu is selected on the phase mode setting operation panel 8, the CPU 1 controls each operation panel 7, Only the phase relationship 152 between the first output wave 113 and the second output wave 118 is changed for the two-phase signal oscillating unit 4 based on the selection / setting value from 8 and 9 and the program setting value, and φ = approximately 180 Degree.

  The two-phase signal oscillating unit 4 is connected to the first output control unit 5 based on Asin (θ) as shown in FIG. Based on Asin (θ + φ), the second output control unit 6 outputs the second ultra-low frequency signal polarity value 116 shown in FIG. 6d and the second ultra-low frequency signal shown in FIG. 6e. The amplitude value 117 of the very low frequency signal is output.

  As in the case of “rotation”, the two-phase signal oscillating unit 4 provides the CPU 1 with one cycle of the first output wave 113 defined by the polarity value 111 and the amplitude value 112 of the first very low frequency signal. A timing signal 154 for each cycle, and a timing signal 154 for each cycle of the second output wave 118 defined by the polarity value 116 and the amplitude value 117 of the second very low frequency signal.

  That is, the two-phase signal oscillating unit 4 notifies the CPU 1 of the timing of θ = 360 degrees and the timing of θ + φ = 360 degrees, and maintains the synchronization between the two-phase signals.

  The first output control unit 5 changes the intermittent wave 106 shown in FIG. 6a by the polarity value 111 of the first very low frequency signal shown in FIG. 6b, generates a waveform similar to FIG. 3c (not shown), and FIG. 3 is output as the first output wave 113 between the first electrode 11 and the second electrode 12 (not shown). .

  The second output controller 6 changes the intermittent wave 106 shown in FIG. 6a by the polarity value 116 of the second very low frequency signal shown in FIG. 6d to generate a waveform similar to FIG. 3c (not shown), and FIG. The waveform is modulated with the amplitude value 117 of the second ultra-low frequency signal shown in FIG. 3 and a waveform similar to that shown in FIG. 3e is output as the second output wave 118 between the first electrode 11 and the third electrode 13 (not shown). .

  The first output wave 113 is positive and the second output wave 118 is negative half cycle, and the first output wave 113 is negative and the second output wave 118 is positive half cycle alternately. The effect can be realized.

  When the frequency value 151 is set to about 0.05 Hz, a slow “left and right fir tree” effect can be obtained. As the frequency value 151 is increased, the right and left moving speed of the “left and right fir tree” effect increases, and when the frequency is increased to about 10 Hz, the sense of “left and right fir tree” cannot be obtained.

  Further, as indicated by a broken line 201 in FIG. 6g, the phase of the second output wave 118 with respect to the first output wave 113 is, for example, 30 degrees from the state where the polarity is inverted (φ = approximately −180 degrees), By proceeding (φ = approximately −150 degrees), a state of “stroking from right to left” can be realized.

  On the contrary, as shown by the broken line 202 in FIG. 6g, the phase of the second output wave 118 with respect to the first output wave 113 is, for example, 30 degrees from the state where the polarity is inverted (φ = approximately −180 degrees). By further delaying (φ = approximately −210 degrees), a state of “stroking from left to right” can be realized.

  It should be noted that the degree of further advancement or delay from φ = approximately −180 degrees is not limited to 30 degrees, and 10 to 30 degrees is likely to exert an effect. If it is about 10 degrees, it feels like it is lightly stroked, and if it is about 30 degrees, it feels like it is stroked strongly.

  As described above, according to the present embodiment, the position of the electrode is changed with only two output control units and three electrodes, with the feeling of “rotating scissors”, “upper and lower fir”, and “left and right fir”. Therefore, it is possible to provide a waveform generator that can be obtained without any problems, and it is difficult to cause electrode connection mistakes or entanglement of lead wires during treatment, and can easily clean up electrodes after treatment.
