Hereinafter, embodiments that are examples of the present invention will be described with reference to the drawings. The electrotherapy device according to the present invention stimulates a living body by outputting an electric signal having a predetermined waveform to the living body.

(Output waveform)
FIG. 1 is a diagram showing an example of an output waveform of an electrotherapy device according to an embodiment of the present invention. Various waveforms can be considered depending on the purpose of treatment, and examples are shown below.

The waveform 110 is obtained by superimposing a pulse wave on a low frequency base wave 111, and is shown by superimposing a high frequency pulse 112. Preferably, the base wave 111 on the superimposed side is a square wave, and the high frequency pulse 112 is superposed on the upper end of the base wave 111 at the lower end. As an example, here, the high frequency pulse 112 is superimposed on the entire time width in both the positive and negative directions of the base wave 111.

In the present application, the low frequency refers to a frequency region of 0.2 Hz to 1.2 KHz, and the high frequency refers to a frequency region higher than the low frequency, that is, higher than 1.2 KHz and up to several hundred KHz. Here, a high frequency (continuous wave, pulse wave) of preferably 2 KHz to 20 KHz, more preferably 4 KHz to 11 KHz is used.
Although the above definition is used in the present application, 1 KHz or less may be defined as a low frequency, 1 KHz to 10 KHz may be defined as a medium frequency, and 10 KHz or more may be defined as a high frequency. In this case, the medium frequency pulse may be superimposed on the low frequency base wave, or the high frequency pulse may be superimposed on the low frequency base wave.

The output intensity at the uppermost end of the waveform 110 is a value corresponding to H3, which is the sum of the amplitude h1 of the base wave 111 and the amplitude h2 of the high frequency pulse 112. Details of the formation of the waveform 110 will be described later.

In this way, by using a synthetic wave that synthesizes a high-frequency pulse with a low-frequency basal wave, electrical stimulation is reduced, and low-frequency stimulation (for example, stimulation for muscles, tendons, etc.) and high-frequency stimulation (for example, internal organs and cells). Stimulation to tissues etc.) is added at the same time, and both effects can be improved.

The waveform 110 may have a waveform rounding 113. As an example, the waveform blunt 113 is formed at one or both of the upper end of the high frequency pulse 112 on the side where the base wave rises in both positive and negative directions and the upper end of the high frequency pulse 112 on the side where the base wave falls.

By providing the waveform bluntness, the electrical stimulation can be further reduced, and it is effective in the case of a low frequency of about 0.5 Hz to 400 Hz, particularly 0.5 Hz to 130 Hz. Preferably, a waveform rounding is provided at a low frequency of 0.5 Hz to 100 Hz.

FIG. 2 is a diagram showing another example of the output waveform. The waveform rounding may be formed at other positions in the waveform 110. As an example, as shown in the illustrated waveform rounding 114, it is formed at one or both of the lower end of the high frequency pulse 112 on the side where the positive ground wave rises and the lower end of the high frequency pulse 112 on the side where the base wave falls.

FIG. 3 is a diagram showing another example of the output waveform. It is known that the human body has capacitance. Even if a square wave voltage signal as shown by the solid line in FIG. 3 (a) is output to the human body, the human body has a waveform blunt 115 on the rising side as shown by the broken line in FIG. 3 (a).

In order to make the waveform applied to the human body a square wave having no waveform bluntness, as shown in FIG. 3B, the waveform 120 having the rising end of the output waveform to the human body protruding (having a protruding portion 122) It is conceivable to do. Such a waveform is effective at a low frequency of 300 Hz or higher, particularly 500 Hz or higher.

FIG. 4 is a diagram showing another example of the output waveform. The output waveform may be a waveform 130 in which a high frequency pulse 132 is superimposed on the upper end of a base wave 131 which is a low frequency pulse. In this case as well, a waveform rounding may be formed.

FIG. 5 is a diagram showing another example of the output waveform. Many waveforms have the same positive and negative pulse widths as shown in FIG. 5A, but one or both of the basal wave and the pulse wave superimposed on the basal wave are shown in the positive direction as shown in FIG. 5B. The waveform 140 may have different pulse widths in the negative direction.
For example, as shown in the figure, a high-frequency pulse may be superimposed on the upper end of a base wave having different pulse widths in the positive and negative directions over the entire time width of the positive and negative pulse widths to form a composite wave. Alternatively, a high frequency pulse may be superimposed only on the negative pulse width to form a composite wave. By forming waveforms with different positive and negative waveforms and outputting them alternately, it is possible to simultaneously give stimuli to different parts, so that the burden can be reduced and efficiency can be improved even if the waveforms are continuously applied. Further, not only the waveforms in the positive and negative directions may be different, but also the waveforms may be appropriately adjusted such as different waveforms every several cycles.

6A and 6B are diagrams showing other examples of output waveforms, FIG. 6A is a conventional example, and FIGS. 6B and 6C are diagrams showing an example of the present invention. In each figure, the solid line shows the voltage waveform applied to the human body, and the broken line shows the voltage waveform that is supposed to be applied (feel) to the human body as a result.

As shown in FIG. 6A, when a square wave is output to the human body, the waveform applied to the human body has a bluntness shown by a broken line.

As shown in FIG. 6B, the waveform 130 shown by the solid line may be output to the human body. In this case, the waveform applied to the human body is as shown by the broken line. The waveform 130 can be considered to have a pulse wave (low frequency to high frequency pulse) 132 having a pulse width b superimposed on the upper end of a low frequency pulse 131 having a pulse width a which is a base wave. Here, the pulse wave 132 is superimposed on the entire time width of the base wave 131, and the amplitude of the pulse wave 132 is further changed.

As shown in FIG. 6C, the waveform 150 shown by a solid line may be output to the human body. In this case, the waveform applied to the human body is as shown by the broken line. The waveform 150 has two low-frequency pulses 152 having a pulse width b superimposed on the upper end of the low-frequency pulse 151 having a pulse width a, which is a base wave, and two pulse widths c on the upper end of the low-frequency pulse 152. It can be considered that the low frequency pulse 153 is superimposed.

As shown in FIGS. 6 (b) and 6 (c), the degree of stimulation applied to the human body can be reduced by forming a waveform in which a low-frequency or high-frequency pulse is superimposed on a low-frequency pulse.

FIG. 7 is a diagram showing an output waveform of one phase in one treatment. The treatment of outputting an electric signal having a waveform as described above for the human body can be subdivided into a plurality of phases. By subdividing into a plurality of phases and combining waveforms of a plurality of phases having different shapes, it becomes easy to construct a treatment pattern according to the purpose of treatment. One procedure can include, for example, up to 45 phases.

The waveform of the illustrated phase is an example in which the output intensity gradually changes at the start and end of the phase. Details will be described later, but at the start of one treatment, at the beginning of a phase that is a transitional period from the previous phase, and at the end of a phase that is a transitional period to the next phase, the output intensity is weakened and gradually. Can be changed to. As a result, the irritation felt by the human body can be reduced, and the impression of a polite treatment can be given.

Further, an interval period may be provided at the end of the phase so that the electric signal is not output before the transition to the next phase. By providing an interval time, it is possible to make the treatment less tiring.

FIG. 8 is a diagram showing output waveforms of a plurality of phases in one treatment. Here, a waveform having one cycle for each phase will be illustrated and described for each of the three phases. The waveforms of the plurality of phases in one treatment may be the same in all phases, but may be different for each phase.

As an example, the frequency of the base wave 151 for each phase may be gradually increased. That is, the frequency of the base wave 151 may be higher in the later phase in the output order. For example, the frequency of the second phase base wave 151 is higher than the frequency of the first phase base wave 151, and the frequency of the third phase base wave 151 is higher than the frequency of the second phase base wave 151. To do. For example, the frequency of the base wave of the first phase is selected in the range of 20 Hz or more and less than 125 Hz, the frequency of the base wave of the second phase is selected in the range of 125 Hz or more and less than 400 Hz, and the frequency of the base wave of the third phase is selected. Is selected in the range of 400 Hz or higher. Even if the same voltage is applied, the high frequency feels less stimulating than the low frequency. By doing so, the stimulus can be gradually reduced.

As an example, the amplitude of the base wave 151 for each phase may be gradually increased. That is, the amplitude of the base wave 151 may be larger in the later phase. For example, the amplitude of the second phase base wave 151 is higher than the amplitude of the first phase base wave 151, and the amplitude of the third phase base wave 151 is higher than the amplitude of the second phase base wave 151. To do. By doing so, the stimulation can be gradually improved. If the frequency of the basal wave 151 for each phase is gradually increased and the amplitude is gradually increased, the stimulus can be softened.

As an example, the amplitude of the pulse wave 152 superimposed on the base wave 151 for each phase may be gradually increased. That is, the amplitude of the superimposed pulse wave 152 may be larger in the later phase. The user may manually increase the output intensity as the phase progresses. By gradually increasing the amplitude of the pulse wave 152 for each phase, it is possible to eliminate the need for user operation and average the stimuli felt.

As an example, the pulse width of the pulse wave 152 superimposed on the base wave 151 can be changed, the pulse width of the pulse wave 153 superimposed on the pulse wave 152 can be changed, or the amplitude of the pulse wave 153 can be changed.

By combining any or all of the above, it is possible to suppress the fluctuation of the stimulus felt by the user, make the stimulus or the effect uniform, and eliminate the need for the user to adjust the output intensity during the treatment.
Here, the output intensity between phases is reduced to 0, but the present invention is not limited to this. The time may be shortened by starting the rise of the next phase from 50%, for example, when the current phase has dropped to 50% without dropping to 0. The details of the decrease and increase of the output intensity will be described later.
In addition, the output intensity that actually expresses the effect differs depending on the frequency, constitution, etc., and for example, the effect may be felt only when the body feels tingling, or it may seem that the effect is effective. However, in reality, the output intensity is often too strong.
On the other hand, the placebo effect due to the tingling may appear.
For these reasons, for example, a high-frequency pulse (for example, pulse wave 153) having an output intensity higher than that of the base wave (for example, 2 to 20 times the frequency of the base wave) is periodically added (for example, all of the base waves). Instead, for example, by outputting at a frequency of 1 to 20 times per second between 1 second and 10 seconds), you can feel a moderately reasonable stimulus and do not increase the output intensity too much. You can consider it.

(Waveform formation)
11 and 12 are diagrams showing an example of forming an output waveform, FIG. 11 is a diagram showing an example of data showing a waveform for one cycle, and FIG. 12 is a diagram showing an example of forming a waveform for one phase. ..

Here, an example of a waveform 110 in which a high-frequency pulse 112 is superimposed on the entire period of a base wave 111, which is a low-frequency square wave, will be described. For example, a high frequency pulse 112 that is 20 times its frequency is superimposed on the upper end of the base wave 111. The frequency of the high frequency pulse 112 is, for example, 5 KHz. Further, the waveform 110 has waveform bluntness at the upper end and the lower end of the high frequency pulse 112 on the rising side and the falling side of the base wave 111.

When observing one cycle of the waveform 110, it is said that the fluctuation is equal to the amplitude h2 of the high-frequency pulse with respect to the output intensity of the base wave 111, but the fluctuation is uneven due to the waveform bluntness. It turns out that it is difficult to show it uniformly.

Therefore, here, the period T of the waveform 110 is subdivided into a plurality of periods according to the rise and fall of the base wave 111 and the high frequency pulse 112. Then, the output intensity of each period is the ratio of the output intensity of the period to the output intensity of the uppermost end of the waveform 110, that is, the output intensity corresponding to h3 which is the sum of the amplitude h1 of the base wave 111 and the amplitude h2 of the high frequency pulse 112. Indicated by. Then, the waveform 110 for one cycle can be shown by the ratio of the output intensity for each period and the time width of the period (here, the period during which the output intensity of the ratio lasts).

By showing the waveform 110 in this way, it is possible to easily form a waveform having a waveform bluntness. Further, even when the waveform rounding extends over two cycles or more, it can be easily formed.

In the case of the figure, one cycle T of the waveform 110 is subdivided into the first period to the 40th period in which the time width t is 100 μs. Of the one cycle T, the first to twentieth periods of the half cycle (1 / 2T) are the waveform portions in the positive direction, and the 21st to 40th periods of the half cycle (1 / 2T) are the waveform portions in the negative direction.

The time width t of the period can be indicated corresponding to the time interval of the timer interrupt. For example, when the time interval of the timer interrupt is 10 μs, the time width of 100 μs can be indicated by 10. By doing so, it is possible to easily generate a waveform.
The timer interrupt time does not necessarily have to use the timer interrupt. For example, the time may be monitored under the monitoring of the OS, and the mechanism operates under the same time management as the timer interrupt shown here. It would be nice if there was.
In addition, when a microcontroller (PIC, etc.) is used, the time division processing (function) is incorporated in advance, for example, a plurality of time division processing is provided and the number of the corresponding time division processing is specified. You may. These are also regarded here as processing equivalent to timer interrupts.

For example, in the waveform portion of the first period, the ratio of the output intensity can be indicated by 90 and the time width can be indicated by 10. Further, in the waveform portion of the second period, the ratio of the output intensity can be indicated by 90 and the time width can be indicated by 10. The periodic data table 410 for storing such periodic data (cycle data) is stored in the storage unit 215.

As shown in FIG. 12, a one-phase waveform can be formed using periodic data. When the transition period is not provided, the waveform shown in the periodic data may be generated and output for the time width of the phase.

When a gentle transition period (q1, q3) is provided at the start or end of the phase, it is necessary to change the output intensity separately from the periodic data. Details will be described later, and a brief description will be given here.

Before and after the normal period q2 that outputs a waveform of the normal output intensity (standard output intensity), an ascending period q1 and a descending period q3 in which the output intensity gradually changes are provided, and in the ascending period q1, the output intensity is from 0 to the standard output. A waveform in which the output intensity does not fluctuate in the normal period q2 is generated, and a waveform in which the output intensity gradually decreases from the standard output intensity to 0 is generated and output in the descending period q3.

When the time width of one phase is 3 minutes, for example, in the ascending period q1, the output intensity is increased in 12 steps (1st to 12th steps) every second, and in the descending period q3, 12 steps are taken every second. In (1st to 12th stages), the output intensity is reduced. When the rest period (interval period) q4 is 5 seconds, the time width of the normal period is 2 minutes and 31 seconds. The ascending period, the descending period, and the resting period may be collectively referred to as an interval period, but here, the resting period is expressed as an interval period.

The frequency of the basal wave, the time width of the phase, and the standard output intensity can be selected according to the purpose of treatment.

FIG. 13 is a diagram showing an example of frequency, phase time width, and standard output intensity. As an example, in the waveform 110, the frequency of the basal wave can be set according to the purpose of treatment, and the phase time width, the standard output intensity, and the frequency of the superimposed pulse wave can be set accordingly. For example, when 19 Hz is set as the frequency of the base wave 111, the phase time width can be set to 3 minutes, the standard output intensity can be set to 1 V, and the frequency of the superimposed pulse wave can be set to 800 Hz.

The frequencies of the base waves are, for example, 14, 16, 19, 21, 25, 27, 59, 61, 71, 73, 94, 96, 119, 121, 124, 126, 159, 161, 441, 447, 449, 464, 466, 499, 501, 599, 601, 624, 626, 659, 661, 665, 667, 689, 691, 699, 701, 724, 726, 727, 728, 729, 731, 739, 741, 769, 771, 775, 777, 786, 788, 789, 791, 799, 800, 801, 802, 803, 804, 805, 831, 839, 874, 876, 879, 881, 884, 886, 891, 1499, 1501, 1549, 1551, 1559, 1561, 1569, 1571, 1599, 1601, 1799, 1801, 1839, 1841, 1849, 1851, 1899, 1901, 1997, 1999, 2001, 2007, 2009, 2051, 2099, 2101, 2121, You can choose from 111 different frequencies: 2126, 2127, 2128, 2129, 2131, 2488, 2489, 2490, 2491, 2999, 3001, 4999, 5001, 9999 and 10001 Hz.

For example, when the purpose is to alleviate the symptoms of acquired immunodeficiency, among the above frequencies, 21, 59, 73, 94, 99, 121, 126, 447, 449, 464, 466, 499, 599, 626, 659, 667, 728, 739, 777, 788, 791, 799, 802, 805, 881, 1499, 1549, 1571, 1601, 1799, 1839, 1999, 2001, 2009, 2128, 2488, 2489, 2490, 2491, One or more can be selected from 4999, 9999. In addition, all of these frequencies may be used in a single treatment, or all may be used in a few treatments.

For example, when the purpose is to reduce the symptoms of allergic symptoms, one of the above frequencies can be selected from 667, 726, 741, 786, 791, 879, 4999, and 5001. For example, when the purpose is to reduce the symptoms of anthrax, it can be selected from 665, 728, 739, 788, 791, and 879. For example, in the case of an infectious disease such as bubonic plague, it can be selected from 19, 61, 73, 94, 124, 499, 501, 4999.

It is thought that the above frequency not only stimulates muscles, nerves, and bones due to changes in electric current, but also stimulates and damages bacteria and viruses, and shakes cells to expel unnecessary substances inside the cells. It is also said to be a frequency that is harmless to the body.

As will be described later, the above frequencies are grouped so that, for example, those in the range of ± 3 Hz are included in the same group, a representative frequency that is a substantially intermediate value is set for each group, and this representative frequency is used for treatment. You may use it.

Further, a plurality of periodic data may be set using such a representative frequency, and the same periodic data may be repeated every one or several cycles to form a waveform in consideration of all the 111 types of frequencies. Such a method is effective when a CPU having a low number of operating clocks (for example, an operating clock of 100 MHz or less) is used.

Grouping is done as follows, for example. The first group includes 19, 21 Hz and has a representative frequency of 20 Hz. The second group includes 59, 61 Hz and has a representative frequency of 60 Hz. The third group includes 124 and 125 Hz, and the representative frequency is 125 Hz. The fourth group includes 665 and 667 Hz, and the representative frequency is 666 Hz. The fifth group includes 726, 727, 728 Hz and has a representative frequency of 727 Hz. The sixth group includes 739, 741 Hz and has a representative frequency of 740. The seventh group includes 786, 788, 789, 791 Hz and has a representative frequency of 790 Hz. The eighth group includes 879,881 Hz, and the representative frequency is 880 Hz. The ninth group includes 4999,5001 Hz, and the representative frequency is 5000 Hz. The tenth group includes 9999 and 10001 Hz, and the representative frequency is 10000 Hz. In this way, what is considered to be highly effective (it is said) can be grouped into 10 groups.

If periodic data is constructed using all of these 10 groups and output continuously, it will be a sequence of frequency waveforms that can promote cell activation and alleviate pain. In this way, by setting so as to correspond to a wide range of symptoms, it is possible to configure an electrotherapy device that can be easily used.

In addition to the above group, for example, a frequency for the purpose of alleviating the symptoms of acquired immunodeficiency can be selected as a basal wave to form periodic data, and periodic data can be selected according to the purpose of treatment. It may be.

Further, together with the above 10 groups, periodic data may be formed by using one or a plurality of frequencies not included in these to form an output waveform. Further, the grouping may be adjusted by adding frequencies having different values to the above 10 groups or changing the representative frequencies. For example, only those having a frequency of 1200 Hz or less corresponding to a JIS standard home treatment device may be used.

Further, the frequency may be divided into 14 groups from 6 groups to form a phase datar described later. Periodic data composed of groups may be used as phase selection cycle data, and by combining these phases, a simple treatment pattern, a normal treatment pattern, a delicate treatment pattern, or the like may be obtained.

Further, by setting the time width of the phases to, for example, 30 seconds to 3 minutes, preferably 1 minute to 2 minutes and 30 seconds, the load on the human body due to the repetition of a long time width is reduced, and the number of phases to be combined is reduced. Can be increased. For example, when the upper limit of the treatment time is 30 minutes, the maximum number of phases is 10 when the phase time width is 3 minutes, but the maximum number of phases is 15 when the phase time width is 2 minutes. It becomes. In addition, by shortening or lengthening the time width for each phase (according to the selected frequency), one treatment can be configured in a well-balanced manner with an appropriate time allocation according to each of the plurality of selected frequencies. As described above, the plurality of phases in one treatment may have different time widths. The details of the phase data table will be described later.

14 to 17 are diagrams showing an example of a table stored in the storage unit. FIG. 14 is a diagram showing an example of a phase data table and a periodic data table.

The phase data table 430 is a table for storing phase data, and the phase data includes at least information indicating selection cycle data, which is cycle data selected from the cycle data table described later, and information indicating a predetermined number of times. As an example, the phase data is composed of a selection cycle data number 431 (which may be an address), an ascending period repeating number 432, a normal period repeating number 433, a descending period repeating number 434, and an interval period repeating number 435. The phase data table 430 has hundreds or less, preferably 10 to 50 phase data.

The selection cycle data number 431 is a number of the cycle data selected from the cycle data stored in the cycle data table 440.

The periodic data table 440 is a table for storing periodic data, and the periodic data contains at least information indicating the ratio of the output intensity of each period to the output intensity at the uppermost end of the period and information indicating the time width of the period. Including. As an example, the period data is composed of the period number 441 of the waveform unit, the period number 442 of one cycle, the output intensity ratio 443 for each period, and the time width 444. The periodic data may further include an interrupt time (timer interrupt time interval) 445.

The number of cycles 441 of the waveform unit is the number of cycles included in one waveform unit. The waveform unit is a waveform having a predetermined time width including a plurality of periods. As will be described later, the waveform generation unit 214 repeatedly generates a waveform for a predetermined number of times in units of waveform units. The predetermined time width of the waveform unit is set according to the time width of the phase and the like, and is, for example, 1 second.

The number of periods 442 in one cycle is the number of periods in one cycle. As described above, one cycle is subdivided into a plurality of periods according to the rise and fall of the base wave and the pulse wave superimposed on the base wave, and the number of the periods is stored here. The output intensity ratio 443 and the time width 444 are registered in pairs for the number of periods (the output intensity ratio of the first period, the time width of the first period, ... The output intensity ratio of the nth period, nth. Time width of the period).

Returning to the description of the phase data table 430. The ascending period repeat count 432 is the number of times that the waveform unit of the selected periodic data number 431 is repeatedly formed in the ascending period of the phase.

As described above, the output intensity is gradually increased in the ascending period of the phase, but when the output intensity is increased in 12 steps every 1 second, the number of repetitions here is 12, and the operation time is 12 seconds. The rate of increase in output intensity for each repetition may be included in the phase data together with the number of repetitions in the rising period.

The normal period repetition number 433 is the number of times that the waveform unit of the selected periodic data number 431 is repeatedly formed in the normal period of the phase.

The number of repetitions of the descending period 434 is the number of times that the waveform unit of the selected periodic data number 431 is repeatedly formed in the descending period of the phase. When raising in 12 steps every 1 second, the number of repetitions here is 12, and the operation time is 12 seconds. The reduction rate of the output intensity for each repetition may be included in the phase data together with the number of repetitions in the descending period.

The number of repetitions in the interval period 435 is the number of repetitions of the waveform unit whose output is 0.

In this way, a series of waveforms of one phase can be briefly shown for each waveform unit. Further, if the predetermined period width of the waveform unit is set to 1 second, the value of the number of repetitions becomes the value of the number of operating seconds, and the output waveform can be formed more concisely. Alternatively, the number of seconds may be simply set and the set number of seconds may be waited for.

FIG. 15 is a diagram showing an example of a treatment data table. The treatment data table 450 is a table for storing treatment data, and the treatment data includes at least information indicating a plurality of phase data selected from the above-mentioned phase data table. As an example, the treatment data includes the treatment name and a plurality of selected phase data numbers. That is, the treatment data is data indicating a combination of phases in one treatment. The treatment data table 450 is stored in the storage unit 215.

When the treatment switching operation is performed by the user, the phase included in the treatment is specified from the selected treatment data number, and the phase data corresponding to each phase data number is read out by referring to the phase data table. Further, the periodic data is read from the selected periodic data number included in the phase data with reference to the periodic data table, and the output waveform is formed based on these.

The stored data can be rewritten in any one or more of the periodic data table, the phase data table, and the treatment data table. Various waveforms can be supported by rewriting the ratio of the output intensity of each period of the cycle data, the number of cycles of the waveform unit, the selection cycle data number, the number of repetitions, the phase data number, and the like.

FIG. 16 is a diagram specifically showing an example of periodic data in the periodic data table.

First, an example of a waveform will be described. The waveform 120 has a period T of 10 ms and a frequency of 100 Hz. More specifically, the waveform 120 is obtained by superimposing the low frequency pulse 122 on the upper end of the rising side of the low frequency continuous square wave (basal wave) 121. The low frequency pulse 122 has a frequency equivalent to that of the base wave 121 and has a narrow pulse width, for example, 1 ms.

One cycle of the waveform 120 can be subdivided into four periods from the first period to the fourth period according to the rising and falling edges of the base wave 121 and the low frequency pulse 122.

The first period and the third period are periods in which the basal wave 121 and the low frequency pulse 122 rise and the high output intensity lasts for a short time, the ratio of the output intensity is 100%, and the time widths t1 and t3 are 1 ms. .. The second and fourth periods are periods in which the low frequency pulse 122 falls and the low output intensity of the basal wave 121 lasts for a long time, the ratio of the output intensity is 80%, and the time widths t2 and t4 are 4 ms. is there.

The periodic data table 440 has periodic data (periodic data number 100) showing the waveform 120.

In this period data, the number of periods of the waveform unit is 100 because the frequency of the base wave of the waveform 120 is 100 Hz when the predetermined time width is 1 second. The number of periods in one cycle is four.

The values of the output intensity ratio and the time width in the first period are 100 and 100. The ratio of the output intensity in the first period (here, the voltage ratio) is 100%, and is indicated by 100. The time width of the first period is 1 ms, but can be indicated by 100 when the time interval of the timer interrupt described later is 10 μs. The ratio of the output intensity and the time width of the second period to the fourth period can be indicated by 80, 400, -100, 100, -80, 400, respectively.

FIG. 17 is a diagram showing a repeating example of the waveform unit in the rising phase of the phase.

As mentioned above, the output intensity is gradually increased to the standard output intensity during the rising phase. Such a rising waveform can be easily formed by repeating the waveform unit.

More specifically, for example, when increasing the output intensity in 12 steps, it can be formed by repeating the waveform unit 12 times. First, the first time, the waveform unit 1 whose output intensity is 1/12 of the standard output intensity is generated. Next, the second time, the waveform unit 2 whose output intensity is 2/12 of the standard output intensity is output. In this way, when the waveform unit 12 is generated by repeating 12 times while increasing the output intensity by 1/12, the output intensity reaches the standard output intensity. If the time width of the waveform unit is 1 second, the time width of the rising period is 12 seconds.

The standard output intensity is set as the initial voltage and then determined by adjusting the output level by the output adjustment operation. For example, when the standard output intensity is 3V and the pull-up rate in the rising period is 1/12, the output intensity of the first waveform unit 1 is 0.25V. Then, the output intensity of the waveform unit 1 in the first period is 0.25V, which corresponds to 100% of the output intensity, 0.25V, which corresponds to 80% of the output intensity in the second period, and the output intensity in the third period is -0.25V. , The output intensity in the 4th period is -0.2V.

18 to 21 are flowcharts showing an example of processing performed by the waveform generation unit of the electrotherapy device according to the embodiment of the present invention.

As shown in FIG. 18, when the power is turned on, the waveform generation unit 214 performs initialization processing such as initializing the value of the variable (S501). The variable start indicating the start / stop state is set to 0 indicating before the start. The variable start is set to 1 indicating the start state when the start / stop switch 211 is pressed, 2 indicating the stop state when the start / stop switch 211 is pressed again, and then the start / stop switch is set again. When 211 is pressed, 1 indicating the start state is set, and when the end state waits for the power to be turned off, 9 is set.
Basically, the circuit starts the initial start when the power is turned on, but at this time, a careless current before control flows to the D / A converter part. In order to cut off these, it is necessary to cut off the output circuit and connect the circuit in the start state until the start SW is turned on. For example, the port is turned on when the start SW is turned on, and the circuit is turned on by a photocoupler or the like.

The waveform generation unit 214 is in a standby state until it is determined to be in the end state (S502), and repeatedly performs operation monitoring processing (S503).

FIG. 19 is a flowchart showing an operation monitoring process. When the start / stop switch 211 is turned on (yes of S602) when the waveform generation unit 214 is stopped (yes of S601), the waveform generation unit 214 determines whether or not the operation is the first time (S603).

In the case of the first operation (yes of S603), the waveform generation unit 214 performs initial voltage setting processing (S604), and performs display processing such as displaying the voltage level (S607). In the initial voltage setting process, the initial voltage is set as the standard output strength. For the sake of completeness, the initial voltage is a relatively low voltage value, and the user can adjust it step by step by the voltage adjusting unit 210.

When the operation is not the first time (no in S603), that is, when the operation is restarted after the stop, the waveform generation unit 214 performs the stop return setting process (S605) and performs display processing such as displaying the voltage level. (S607). In the case of restarting the operation after the stop, the operation is restarted by returning to the beginning of the phase, but the standard output intensity returns the value at the time of the operation before the stop. However, the standard output intensity may be reduced to, for example, half without necessarily returning, or the output adjustment operation may be performed again after returning to the default value.

In the case of stopping (yes in S601), if the start / stop switch is not turned on (no in S602), the waveform generation unit 214 performs display processing such as displaying the voltage level (S607).

When not stopped (no in S601), the waveform generation unit 214 performs voltage adjustment processing (S606) based on the voltage value stored in the output voltage value memory, and displays the voltage level and remaining time. (S607). As will be described later, the output voltage value memory stores a voltage value obtained by multiplying the standard voltage by a ratio according to the waveform and a ratio according to the mode (rising period, normal period, falling period). The waveform generation unit 214 controls so that the voltage of the stored voltage value is input to the D / A converter while rewriting the value of the output voltage value memory at any time.

FIG. 20 is a flowchart showing timer interrupt processing. The time interval of timer interrupt processing is, for example, 10 μs. The time interval of the timer interrupt may be set to be constant during operation, but may be set for each phase (for example, set in consideration of the time width of the periodic data table 410). This makes it easier to set the time width of the superimposed waveform.

If the waveform generation unit 214 is stopped (yes in S701), the interrupt processing is terminated, but if not (no in S701), the value of the sweep counter that counts the number of interrupts is reduced (S702). , It is determined whether the value of the sweep counter is 0 (S703).

When the value of the sweep counter is 0 (yes in S703), the next period processing for setting the data for the next period is performed (S704). If the value of the sweep counter is not 0 (no in S703), the interrupt processing ends.

FIG. 21 is a flowchart showing the next period processing. In the variable mode, 1 is set when the phase is in the ascending period, 2 is set when it is the normal period, 3 is set when it is the descending period, and 4 is set when it is the interval period. It is designed to be set. The initial value of the term counter is set to 40 in the example of FIG. 11 and 4 in the example of FIG. Further, the initial value of the repeat counter is set to 12 in the rising period, 200 to 300 in the normal period, 12 in the falling period, and 5 in the interval period.

In the next period processing, the waveform generation unit 214 first reduces the value of the term counter that counts the number of periods (S801), and determines whether the value of the term counter is 0 (S802). If the value of the term counter is not 0, it means that one cycle has not ended.

When the value of the term counter is not 0 (no in S802), the waveform generation unit 214 determines whether or not the operation is in the interval period (S803). If the operation is in the interval period (yes of S803), this flow ends.

When the operation in the interval period is not in progress (no in S803), the waveform generation unit 214 performs a process of setting data in the next period (S804), and ends this flow. In the process of setting the data for the next period, the waveform generation unit 214 stores the voltage value in the output voltage value memory based on the "ratio of output intensity" of the periodic data table, and sweeps based on the "time width". Set the counter value.

When the value of the term counter is 0 (yes of S802), the waveform generation unit 214 reduces the value of the repeat counter that counts the number of repetitions of the waveform unit (S805), and whether or not the operation is in the rising period. Is determined (S806).

When the operation in the ascending period is in progress (yes of S806), the waveform generation unit 214 determines whether or not the value of the repeat counter is 0 (S807). When the value of the repeat counter is not 0, it means that the current mode (rising period, normal period, descending period) is in progress.

When the value of the repeat counter is not 0 (no in S807), the waveform generation unit 214 performs the operation setting process of the next waveform unit (“next waveform unit operation setting”) (S808), and ends this flow. Here, in the "next waveform unit operation setting" process, the waveform generation unit 214 sets a voltage value in the output voltage value memory based on the "ratio of output intensity" of the periodic data table, and is based on the "time width". And set the sweep counter value.

Specifically, in the rising period, the output voltage value is raised stepwise (for example, 12 steps), so that in the first "next waveform unit operation setting" process S808, the output voltage is set to the initially set standard output voltage. , The voltage value obtained by multiplying the "ratio of output intensity" of the periodic data table and further multiplying by 1/12 is stored in the output voltage memory. In the second "next waveform unit operation setting" process S808, the voltage value obtained by multiplying 2/12 instead of 1/12 is stored in the output voltage memory. Similarly, at the nth time, the output voltage is obtained and stored by multiplying by n / 12.

When the value of the repeat counter is 0 (yes in S807), the waveform generation unit 214 performs the normal period operation setting process (S809), and ends this flow. In the normal period operation setting process, the waveform generation unit 214 makes settings for the normal period operation. Specifically, the mode is set to 2, and the repeat counter is set to 200 to 300. Further, the voltage value is set in the output voltage value memory based on the "ratio of output intensity" of the periodic data table, and the sweep counter value is set based on the "time width".

When not in operation in the ascending period (no in S806), the waveform generation unit 214 determines whether or not it is in operation in the normal period (S810).

When the operation in the normal period is in progress (yes of S810), the waveform generation unit 214 determines whether or not the value of the repeat counter is 0 (S811), and when the value of the repeat counter is not 0 (S811). No) processes the operation setting (“next waveform unit operation setting”) of the next waveform unit in the normal period (S812), and ends this flow. In the operation setting process of the next waveform unit, the voltage value is set in the output voltage value memory based on the "ratio of output intensity" of the periodic data table, and the sweep counter value is set based on the "time width".

When the value of the repeat counter is 0 (yes in S811), the waveform generation unit 214 performs the descending period operation setting process (S813), and ends this flow. In the descending period operation setting process, the waveform generation unit 214 makes settings for the descending period operation. Specifically, the mode is set to 3 and the repeat counter is set to 12. Further, the voltage value is set in the output voltage value memory based on the "ratio of output intensity" of the periodic data table, and the sweep counter value is set based on the "time width".

When not in operation in the normal period (no in S810), the waveform generation unit 214 determines whether or not it is in operation in the descending period (S814).

When the operation in the descending period is in progress (yes of S814), the waveform generation unit 214 determines whether or not the value of the repeat counter is 0 (S815), and when the value of the repeat counter is not 0 (S815). No) processes the operation setting (“next waveform unit operation setting”) of the next waveform unit in the descending period (S816), and ends this flow.

Specifically, in the falling period, the output voltage value is gradually lowered (for example, 12 steps), so that in the first "next waveform unit operation setting" process S816, the initially set standard output voltage is used. , The voltage value obtained by multiplying the "ratio of output intensity" of the periodic data table and further multiplying by 12/12 is stored in the output voltage memory. In the second "next waveform unit operation setting" process S816, the voltage value obtained by multiplying 11/12 instead of 12/12 is stored in the output voltage memory. At the nth time, the output voltage is obtained and stored by multiplying by (12-n) / 12.

When the value of the repeat counter is 0 (yes in S815), the waveform generation unit 214 determines whether or not all the phases have been completed (S817).

When all the phases are not completed (no in S817), the waveform generation unit 214 performs the interval period operation setting process (S818). In the interval operation setting process, the voltage value 0 is set in the output voltage value memory, and the sweep counter value is set in the same manner as described above. When all the phases are completed (yes in S817), the waveform generation unit 214 performs the termination process (S819).

When the operation in the descending period is not in progress (no in S814), the operation in the interval period is in progress, and the waveform generation unit 214 determines whether or not the value of the repeat counter is 0 (S820). When the value of the repeat counter is not 0 (no in S820), the waveform generation unit 214 performs the next interval operation setting process (S821). When the value of the repeat counter is 0 (yes of S820), the waveform generation unit 214 performs the operation setting process of the next phase (S822).

(Other examples)
For example, the waveform according to the present invention may have at least a part of rising and falling in the period of the waveform slowly rising or falling. As an example, the example in which the pulse wave of the square wave is superimposed on the upper end of the base wave has been described above, but the base wave has a slow rise (step-like rise) and a slow fall (step-like fall). A high frequency such as a sawtooth wave having one or a high frequency such as a triangular wave having both may be superimposed.

In this case, the output intensity of the waveform of one cycle gradually increases or decreases for at least a part of the period, and such a waveform can also be dealt with based on the cycle data. The waveform generation unit 214 is based on the information indicating the ratio of the output intensity of the period and the information indicating the ratio of the output intensity of the period immediately before the period in the periodic data, and / or the output intensity of the period. Based on the information indicating the ratio and the information indicating the ratio of the output intensity in the period immediately after the period, the ratio of the output intensity in the period is changed according to the information indicating the time width of the period (for example, for each interrupt). Can be made to.

For example, when the value indicating the ratio of the output intensity of the second period in the periodic data to the second period is 55 and the value indicating the ratio of the output intensity of the immediately following third period is 100, the value of the second period Depending on the value 10 indicating the time width, the ratio of the output intensity is gradually increased with a uniform width at the interrupt time interval, such as 55, 60, 65, 70, 75, 80, 85, 90, 95, 100. It may be varied to form a waveform (exponential variation, etc.). If the ratio of the output intensity in the immediately following period is smaller than the ratio of the output intensity in the relevant period, it may be gradually reduced by the above method.

By slowing the rise or fall of the superimposed high frequency in this way, a smoother output change with mild stimulation can be obtained.

FIG. 22 is a diagram showing an example of an output waveform of the electrotherapy device according to the embodiment of the present invention. The figure shows an example of a waveform 150 in which a high frequency 152 such as a triangular wave is superimposed, which has a stepped rising edge and a stepped falling edge at the upper end of the base wave 151.

For example, when the value indicating the ratio of the output intensity of the third period in the periodic data to the third period is 90 and the value indicating the ratio of the output intensity of the immediately preceding second period is 80, the thirth of the periodic data. According to the value 10 indicating the time width of the three periods, the ratio of the output intensity is 83, 84, 85, 86, 87, 88 for each interrupt using 8/10 of the time width of the period (8 interrupts) at the rising edge. , 89, 90, etc., and then maintain the output intensity ratio of 90 for 2/10 of the time width of the remaining period (for two interrupts) to form a waveform in which the output intensity ratio is varied. You may.

As described above, the waveform in which the rising or falling of the superimposed pulse wave is slowed down may be formed in any one or more of the rising phase, the normal phase, and the falling phase of the phase.

FIG. 23 is a diagram showing an example of an output waveform of the electrotherapy device according to the embodiment of the present invention. The above example is an example in which the period of the synthetic wave mainly matches the period of the base wave, but the present invention is not limited to this, and may be different.

As shown in the figure, the waveform 160 is obtained by superimposing a high frequency pulse 162 on a base wave 161 which is a low frequency square wave. In the waveform 160, the high frequency pulse 162 is periodically superimposed on the two cycles of the basal wave 161. The period of the waveform 160 corresponds to the two cycles of the basal wave 161. The high-frequency pulse 162 is a pulse group having a pulse period of B whose amplitude fluctuates in a fluctuation cycle corresponding to two cycles of the base wave 161.

In the waveform 160, the amplitude of the superimposed pulse wave 162 fluctuates periodically. The "amplitude" here refers to the pulse width of the high-frequency pulse 162 or the amplitude of the portion corresponding to the pulse width. The amplitude fluctuation period of the superimposed pulse wave 162 is larger than that of the base wave 161 and is twice as large as that of the base wave 161. By connecting the amplitudes of the superimposed high frequency pulses 612, a curve as shown in the figure (curve shown by a broken line) can be obtained. Waveform 160 synthesizes a high-frequency pulse with a low-frequency basal wave, and further, three types of stimuli are obtained by amplitude fluctuations that fluctuate in a fluctuation period (here, twice) with a time width larger than the period of the basal wave. ..

In the waveform 160, the high frequency pulse 162 is superimposed in the positive direction in the first period of the base wave 161 and in the negative direction in the second period of the base wave 161. More specifically, in the first period of the basal wave 161, in the positive pulse width of the basal wave 161, the upper end of the basal wave is superimposed on the lower end in the positive direction (for example, the waveform portion 1601), and the pulse width in the negative direction. Then, the upper end of the base wave is superimposed on the lower end in the positive direction (for example, the waveform portion 1602), and the reference line is superimposed on the lower end in the positive direction (for example, the waveform portion 1603). In the second period of the basal wave 161, the upper end of the basal wave is superimposed on the lower end in the negative direction in the positive pulse width of the basal wave 161 (for example, the waveform portion 1604), and the upper end of the basal wave is superimposed in the negative pulse width. It is superimposed on the lower end in the negative direction (for example, the waveform portion 1605), and otherwise the reference line is superimposed on the lower end in the negative direction (for example, the waveform portion 1606). The waveform 160 is obtained by superimposing the high frequency pulse 162 on the upper end of the base wave 161 in this way.

The waveform 160 can be formed based on the above periodic data. One cycle of the waveform 160 corresponds to two cycles of the base wave 161 and the waveform shown in the figure is a waveform of one cycle of the waveform 160. This one cycle is subdivided into a plurality of periods according to the rise and fall of the base wave 161 and the high frequency pulse 162. Then, the waveform 160 for one cycle can be shown by the ratio of the output intensity of the period to the output intensity of the uppermost end of the waveform cycle and the time width of the period for each of the plurality of periods. Here, unlike the above example, for example, in the period k of the waveform portion 1602, the value of the output intensity ratio is a positive value, but the output intensity ratio in the next period is a negative value.

Note that the illustrated waveform 160 is an example in which the amplitude fluctuation period of the superimposed high-frequency pulse corresponds to twice the period of the base wave, but is shifted from the period of the base wave, such as one corresponding to three times the period of the base wave. It may form a waveform such as an interference wave. Even such a waveform can be easily formed by the electrotherapy device of the present invention.

Further, the waveform 160 may have an amplitude fluctuation period of the superimposed high frequency pulse smaller than the period of the basal wave, which corresponds to 2/3 times the period of the basal wave. In other words, the waveform may be such that the amplitude fluctuation period of the superimposed high-frequency pulse is 2 cycles for 3 cycles of the base wave. In this case, since one cycle of the waveform 160 of the composite wave is considered to correspond to six cycles of the base wave, one cycle is subdivided into a plurality of periods correspondingly.

In the conventional interference wave type treatment, a plurality of pairs of electrodes are used, but according to the electrotherapy device of the present invention, it can be easily realized by a pair of electrodes.

FIGS. 24 to 27 show the cycle data (cycle data), the image of the waveform to be created by the cycle data, and the oscilloscope waveform actually created and output. By the method of the above embodiment, a waveform almost the same as the waveform to be created could be output.
