Description

本発明は干渉低周波治療器に関する。    The present invention relates to an interference low frequency treatment device.

干渉低周波治療器は、周波数が僅かに異なる複数の電流を同時に生体に流し、生体内で発生する干渉低周波電流で刺激をおこなうものである。
従来の低周波治療器は、周波数が１０００Ｈｚ以下の、通常は数十Ｈｚ以下の電流を、皮膚表面に貼付した電極を介して生体に供給していた。しかし、皮膚は図３に示すような抵抗成分Ｒとｒ、容量成分Ｃからなる電気的等価回路を有し、そのインピーダンスは数キロオームと大きいため、出力を大きくすると不快な電気刺激感や痛みが生じ、所望の大きさの電流を流すことができず、十分な治療効果が得られないという問題があった。
これを解決するために開発されたのが干渉低周波治療器である。 The interference low-frequency treatment device is configured to cause a plurality of currents having slightly different frequencies to flow through a living body at the same time and perform stimulation with the interference low-frequency current generated in the living body.
Conventional low-frequency treatment devices supply a current having a frequency of 1000 Hz or less, usually tens of Hz or less, to a living body via an electrode attached to the skin surface. However, the skin has an electrical equivalent circuit composed of resistance components R and r and a capacitance component C as shown in FIG. 3, and its impedance is as large as several kilohms. As a result, there is a problem that a current having a desired magnitude cannot be supplied and a sufficient therapeutic effect cannot be obtained.
In order to solve this problem, an interference low frequency treatment device has been developed.

干渉低周波治療器は、図４のように、周波数が僅かに異なる２つの電流（搬送波）を同時に生体に供給し、２つの搬送波の周波数差の干渉低周波を発生させて生体を刺激（筋収縮）するものである。
搬送波の周波数ｆには数ｋＨｚ（通常は４０００Ｈｚ前後）、のものが使用されている。この周波数は従来の一般的な低周波治療器よりも１桁程度、高いため、皮膚インピーダンスは１／１０程度になり、電気刺激感覚は殆どない。このため、従来よりも大きなエネルギーを供給できる。しかし、４０００Ｈｚ程度の電流単独では筋収縮を得ることはできない。
そこで、周波数が僅かに異なる２つの搬送波を用い、生体内で発生する干渉低周波により、筋収縮を得るようにしている。数〜数十Ｈｚの電流は効果的に筋収縮を得ることができる。
このようにして、干渉低周波治療器では、高い周波数の搬送波を用いることで不快な電気刺激感が無く、従来よりも大きな電気エネルギーを供給することができるようにし、しかも、２つの搬送波を干渉させて発生する干渉低周波で効果的に筋収縮を得ることができるようにしている。
このようにして、干渉低周波治療器は従来の低周波治療器の問題を解決し、高い治療効果を得ることができる。 As shown in FIG. 4, the interference low frequency treatment device supplies two currents (carrier waves) having slightly different frequencies to the living body at the same time, generates an interference low frequency having a frequency difference between the two carrier waves, and stimulates the living body (muscles). (Shrink).
A carrier wave having a frequency f of several kHz (usually around 4000 Hz) is used. Since this frequency is about an order of magnitude higher than that of a conventional general low-frequency treatment device, the skin impedance is about 1/10 and there is almost no sense of electrical stimulation. For this reason, larger energy than conventional can be supplied. However, muscle contraction cannot be obtained with a current of about 4000 Hz alone.
Therefore, two carrier waves having slightly different frequencies are used, and muscle contraction is obtained by the interference low frequency generated in the living body. A current of several to several tens Hz can effectively obtain muscle contraction.
In this way, in the interference low frequency treatment device, by using a high frequency carrier wave, there is no sense of unpleasant electrical stimulation, and it is possible to supply a larger amount of electric energy than before, and the two carrier waves interfere with each other. Thus, the muscle contraction can be effectively obtained at the interference low frequency generated.
In this way, the interference low-frequency treatment device can solve the problems of the conventional low-frequency treatment device and obtain a high therapeutic effect.

以上の説明では、周波数が僅かに異なる２つの搬送波を同時に生体に供給し、生体内で干渉低周波を発生させる干渉低周波治療器について述べたが、搬送波の位相を制御することでも、これと同様の干渉低周波を発生させることができる（例えば特許文献１など）。そのブロック図の例を図６に示す。    In the above description, the interference low frequency treatment device that supplies two carrier waves with slightly different frequencies to the living body at the same time and generates the interference low frequency in the living body has been described. A similar interference low frequency can be generated (for example, Patent Document 1). An example of the block diagram is shown in FIG.

図６は、位相を制御して干渉低周波を発生させる干渉低周波治療器のブロック図である。装置は搬送波発生部６１と、変換器６３と、増幅器６５ａと６５ｂ、制御部６６と、電極６８ａ、６８ｂ、６９ａ、６９ｂから構成される。搬送波発生部６１で発生させた搬送波は増幅器６５ａで増幅されて電極６８ａと６８ｂを介して、生体に供給され、一方、搬送波発生部６１で発生させた搬送波は変換器６３で位相制御され、増幅器６５ｂで増幅され、電極６９ａと６９ｂを介して、生体に供給される。
このとき、変換器６３で、搬送波の位相を、周期δｆで直線状に変化させると、搬送波周波数がｆで干渉低周波の周波数がδｆの干渉低周波を得ることができ、図５（Ｃ）と同じ干渉低周波を得ることができる。
図６の６６は制御部で、搬送波発生部６１や変換器６３を制御し、搬送波の周波数や干渉低周波の波形や周波数などを所望の値に制御することができる。
増幅器６５ａと６５ｂの増幅率は装置の操作パネルに設けた出力調節器の操作量に依存する。
出力調節器を操作して、適切な刺激の強さ（筋収縮や刺激感覚が適切な強さ）になるように、使用する。 FIG. 6 is a block diagram of an interference low-frequency treatment device that generates a low-frequency interference by controlling the phase. The apparatus includes a carrier wave generation unit 61, a converter 63, amplifiers 65a and 65b, a control unit 66, and electrodes 68a, 68b, 69a and 69b. The carrier wave generated by the carrier wave generating unit 61 is amplified by the amplifier 65a and supplied to the living body via the electrodes 68a and 68b, while the carrier wave generated by the carrier wave generating unit 61 is phase-controlled by the converter 63, and the amplifier Amplified at 65b and supplied to the living body via the electrodes 69a and 69b.
At this time, when the phase of the carrier wave is linearly changed with the period δf by the converter 63, an interference low frequency in which the carrier frequency is f and the frequency of the interference low frequency is δf can be obtained. The same interference low frequency can be obtained.
Reference numeral 66 in FIG. 6 denotes a control unit that can control the carrier wave generation unit 61 and the converter 63 to control the frequency of the carrier wave, the waveform and frequency of the interference low frequency, and the like.
The amplification factors of the amplifiers 65a and 65b depend on the operation amount of the output regulator provided on the operation panel of the apparatus.
Operate the output regulator and use it so that the appropriate stimulation intensity (muscle contraction and stimulation sensation is appropriate).

以上のように、従来の干渉低周波治療器は、搬送波１と、搬送波１の周波数又は位相を制御した搬送波２の、２系統の搬送波を生体に流し、生体内で発生する干渉低周波で治療をおこなうものである。
このような、周波数が僅かに異なる２つの搬送波を用いる従来の干渉低周波治療器は、従来の一般的な低周波治療器の問題を解決し、不快感が少ない、効果的な治療をおこなうことはできるが、周波数δｆの干渉低周波のみで筋肉刺激をおこなうため、比較的単調な刺激になり、慣れが生じるという問題があった。
そこで、周波数が異なる３つの搬送波を出力して、３つの干渉低周波を得て、より変化に富む筋肉刺激をおこなうようにした技術も開示されている（例えば特許文献２など）。 As described above, the conventional interference low frequency treatment device treats two carriers of the carrier 1 and the carrier 2 that controls the frequency or phase of the carrier 1 through the living body and treats with the interference low frequency generated in the living body. It is to do.
The conventional interference low-frequency treatment device using two carrier waves having slightly different frequencies solves the problems of the conventional low-frequency treatment device, and provides effective treatment with less discomfort. However, since the muscle stimulation is performed only by the interference low frequency of the frequency δf, there is a problem that the stimulation becomes relatively monotonous and the habituation occurs.
In view of this, a technique has been disclosed in which three carrier waves having different frequencies are output to obtain three interference low frequencies to perform muscle stimulation with more variety (for example, Patent Document 2).

図７は特許文献２のブロック図である。装置は、周波数発生部（図中の符号１１）で周波数αの搬送波を発生し、周波数設定部（図中の符号１５）で周波数βの治療波を発生し、２つの周波数変換器（図中の符号１５Ｂと符号１５Ｃ）で周波数がα＋βとα＋２βの２つの搬送波を作成し、この３つの搬送波を３つの出力部（図中の１４Ａ、１４Ｂ、１４Ｃ）で増幅して生体に供給し、周波数がβと２βの２種類の干渉低周波を得て生体を刺激するようにしている。
このため、従来の干渉低周波治療器では１種類の干渉低周波（周波数がδｆ）で筋肉刺激していたが、特許文献２により、周波数がβと２βの２種類の干渉低周波で筋肉刺激をおこなうことができ、より変化に富んだ刺激を可能になる。電気刺激では、治療を続けるうちに刺激に対して生体の慣れが生じて、治療効果が低下するという問題があったが、特許文献２により電気刺激に対する慣れが少なくなり、より高い治療効果を得ることができる。 FIG. 7 is a block diagram of Patent Document 2. In FIG. The apparatus generates a carrier wave having a frequency α by a frequency generation unit (reference numeral 11 in the figure), generates a therapeutic wave having a frequency β by a frequency setting part (reference numeral 15 in the figure), and generates two frequency converters (in the figure). 15B and 15C), two carrier waves having frequencies α + β and α + 2β are generated, and these three carrier waves are amplified by three output units (14A, 14B, and 14C in the figure) and supplied to the living body. However, two kinds of interference low frequencies β and 2β are obtained to stimulate the living body.
For this reason, in the conventional interference low frequency treatment device, muscle stimulation is performed with one type of interference low frequency (frequency is δf). However, according to Patent Document 2, muscle stimulation is performed with two types of interference low frequencies of β and 2β. Can be stimulated with more variety. In the electrical stimulation, there is a problem that the body becomes accustomed to the stimulation while continuing the treatment and the therapeutic effect is reduced. However, Patent Document 2 reduces the familiarity with the electrical stimulation and obtains a higher therapeutic effect. be able to.

前述のように、特許文献１などの干渉低周波治療器は、従来の一般的な低周波治療器と比して、不快な刺激感が無く、多くの電気エネルギーを生体に供給でき、治療効果が高い。しかし、１つの干渉低周波で生体を刺激するため、比較的単調な刺激しかなく、このため、慣れが生じて、治療効果が低下するという問題があった。
特許文献２は、３つの干渉低周波を発生させて生体を刺激するため、従来の干渉低周波治療器と比して、より変化に富んだ刺激が効能であるため、より高い治療効果が期待できる。
しかし、特許文献２の装置は３組６個の電極を必要とするため、四肢などの小さな部分を治療する場合、電極を貼るスペースがとれず、特長を生かせないという問題を有している。
本発明は、これらの課題を解決し、より少ない電極でより効果的な治療をおこなうことのできる新しいタイプの干渉低周波治療器を提供することを目的とする。 As described above, the interference low-frequency treatment device of Patent Document 1 and the like has no unpleasant irritation compared to the conventional general low-frequency treatment device, and can supply a large amount of electric energy to the living body. Is expensive. However, since the living body is stimulated with one interference low frequency, there is only a relatively monotonous stimulation, and there is a problem that the habituation occurs and the therapeutic effect is reduced.
Since Patent Literature 2 stimulates a living body by generating three interference low frequencies, a more varied stimulation is effective than a conventional interference low frequency treatment device, and thus a higher therapeutic effect is expected. it can.
However, since the device of Patent Document 2 requires three sets of six electrodes, when treating a small part such as an extremity, there is a problem that a space for attaching electrodes cannot be taken and the features cannot be utilized.
An object of the present invention is to solve these problems and to provide a new type of interference low frequency treatment device capable of performing more effective treatment with fewer electrodes.

A carrier wave generator for generating a medium frequency carrier wave having a frequency f;
A therapeutic wave generator for generating a therapeutic wave;
A converter that changes the phase or frequency of the carrier wave generated by the carrier wave generator in a predetermined range;
An adder for outputting the output Wataruhiku frequency interference that Yusuke <br/> frequency to sufficiently contract the muscles by adding those adjusted by the regulator the output of the transducer of the carrier wave generating unit,

Interference low frequency output section having a plurality systems,
At least one of the outputs of the interference low-frequency output units of the multiple systems supplied to the living body is an internal interference low frequency generated by the adder.
It is characterized by that .
Moreover, in invention of Claim 2 of this invention, in invention of Claim 1,
For n internal interference low frequencies, n (n-1) / 2 interference low frequencies are generated in the living body.
It is characterized by that.
Moreover, in invention of Claim 3 of this invention, in invention of Claim 1 thru | or 2,

第１の出力部から、搬送波の周波数がｆで、干渉低周波の周波数δｆ１の、第１の内部干渉低周波を出力し、
第２の出力部から、搬送波の周波数がｆで、干渉低周波の周波数δｆ２の、第２の内部干渉低周波を出力し、
第ｎの出力部から、搬送波の周波数がｆで、干渉低周波の周波数δｆｎの、第ｎの内部干渉低周波を出力し、
各々の出力部から出力するｎ個の内部干渉波で生体を刺激する。
また、これを同時に生体に供給すると、各々の出力部から出力する内部干渉低周波が他の出力部が出力する内部干渉波と干渉し、生体内でｎ（ｎ−１）／２個の干渉低周波が発生し、生体を刺激する。 From the first output unit, the first internal interference low frequency of the carrier wave frequency f and the interference low frequency δf1 is output,
From the second output unit, the second internal interference low frequency of the carrier wave frequency f and the interference low frequency δf2 is output,
From the n-th output unit, the carrier wave frequency is f and the interference low-frequency frequency δfn is output, and the n-th internal interference low-frequency is output.
A living body is stimulated by n internal interference waves output from each output unit.
When this is simultaneously supplied to the living body, the internal interference low frequency output from each output unit interferes with the internal interference wave output from the other output units, and n (n-1) / 2 interferences in the living body. Low frequency is generated and stimulates the living body.

このため、各出力系統から出力するｎ個の内部干渉低周波と、生体内で生じるｎ（ｎ−１）／２個の干渉低周波の、合計ｎ＋ｎ（ｎ−１）／２個の干渉低周波で生体を刺激する。
例えば、本発明で出力系統を２個にすると、周波数がａとｂの２つの内部干渉波を出力し、生体内で、周波数がａ−ｂの干渉低周波が発生し、これらの合計３個の干渉低周波で生体を刺激する。
従来の２組の電流を用いる特許文献１の干渉低周波治療器では、１個の干渉低周波で刺激をおこなっていた。干渉低周波治療器は従来の一般的な低周波治療器よりも高い治療効果を有するが、１個の干渉低周波による比較的単純な刺激であるため、慣れが生じて、治療効果が低下するという問題を有していた。
これに対して本発明では、同じ電極数でより複雑な刺激をおこなうことができるため、慣れはより少なく、このため、特許文献１よりも高い治療効果を得ることができる。 For this reason, a total of n + n (n−1) / 2 interference low frequencies of n internal interference low frequencies output from each output system and n (n−1) / 2 interference low frequencies generated in the living body. Stimulate the living body with frequency.
For example, when the number of output systems is two in the present invention, two internal interference waves with frequencies a and b are output, and an interference low frequency with a frequency ab is generated in the living body. Stimulate the living body with low frequency interference.
In the conventional interference low frequency treatment device of Patent Document 1 using two sets of currents, stimulation is performed with one interference low frequency. Interfering low frequency treatment devices have a higher therapeutic effect than conventional general low frequency treatment devices, but because they are relatively simple stimuli due to a single interference low frequency, habituation occurs and treatment effects are reduced. Had the problem.
On the other hand, in the present invention, since more complex stimulation can be performed with the same number of electrodes, there is less habituation, and therefore a higher therapeutic effect than that of Patent Document 1 can be obtained.

従来の３組の電流を用いる特許文献２の干渉低周波治療器では、生体内で３個の干渉低周波を発生させて刺激をおこなっていた。このため、特許文献１よりも複雑な、より慣れの少ない刺激が可能で、このため、特許文献１よりも高い治療効果が得られている。
これに対して本発明では、特許文献２で開示されている３組の電極ではなく、２組の電極を使用して、特許文献２と同じ数の干渉低周波の刺激をおこなうことができるため、特許文献２と同等の治療効果が期待できる。しかも、本発明では２組の電極しか要しないため、特許文献２では治療が不可能であった電極が貼れないような小さな患部の治療も可能である。つまり、本発明の適応範囲は特許文献２よりも広くなる。
ｎ系統の出力数にすると、前述のように、ｎ＋ｎ（ｎ−１）／２個の干渉低周波で生体刺激をおこなうため、複雑で、慣れの少ない刺激をおこなうことができ、治療効果を向上させることができる。 In the conventional interference low frequency treatment device of Patent Document 2 using three sets of currents, stimulation is performed by generating three interference low frequencies in a living body. For this reason, the irritation | stimulation which is more complicated than patent document 1, and is less accustomed is possible, Therefore The therapeutic effect higher than patent document 1 is acquired.
On the other hand, in the present invention, the same number of interference low-frequency stimulations as in Patent Document 2 can be performed using two sets of electrodes instead of the three sets of electrodes disclosed in Patent Document 2. A therapeutic effect equivalent to that of Patent Document 2 can be expected. In addition, since only two sets of electrodes are required in the present invention, it is possible to treat a small affected area where an electrode that cannot be treated in Patent Document 2 cannot be applied. That is, the applicable range of the present invention is wider than that of Patent Document 2.
When the number of outputs is n, as described above, biostimulation is performed with n + n (n-1) / 2 interference low frequencies, so that complex and less accustomed stimulation can be performed, and the therapeutic effect is improved. Can be made.

以下に、出力系統を２系統にした実施例を中心に、本発明を説明する。    Hereinafter, the present invention will be described focusing on an embodiment in which two output systems are used.

本発明の請求項１に係る発明の一実施例について以下に説明する。
本発明の干渉低周波出力部を２系統にした実施例のブロック図を図１に示す。
装置は、搬送波発生部１と、治療波発生器２ａ、周波数変換器３ａ、調整器７ａ、加算器４ａ、増幅器５ａ、及び電極８で構成する第１の出力系統（干渉低周波出力部）と、搬送波発生部１と、治療波発生器２ｂ、周波数変換器３ｂ、調整器７ｂ、加算器４ｂ、増幅器５ｂ、電極９とで構成する第２の出力系統（干渉低周波出力部）と、
制御部６と、
で構成される。 An embodiment of the invention according to claim 1 of the present invention will be described below.
FIG. 1 shows a block diagram of an embodiment in which the interference low-frequency output unit of the present invention has two systems.
The apparatus includes a carrier wave generator 1, a treatment wave generator 2a, a frequency converter 3a, a regulator 7a, an adder 4a, an amplifier 5a, and an electrode 8 and a first output system (interference low frequency output unit). A second output system (interference low-frequency output unit) composed of a carrier wave generator 1, a treatment wave generator 2b, a frequency converter 3b, a regulator 7b, an adder 4b, an amplifier 5b, and an electrode 9.
A control unit 6;
Consists of.

本発明の動作を、図１のブロック図、及び図２の干渉低周波の例の説明図を基に下記にて説明する。
制御部６は、搬送波発生部１、治療波発生器２ａ及び２ｂ、周波数変換器３ａ及び３ｂ、加算器４ａ及び４ｂ、増幅器５ａ及び５ｂ、調整器７ａ及び７ｂ、及び図に記載していないが装置の操作部の入力を読み取り、それに応じて表示部を含む装置全体を制御する。
搬送波発生部１は制御部６で制御されて、所定の周波数ｆの搬送波を発生する。搬送波の周波数は設定した値に制御できるが、固定でも良い。
治療波発生器２ａと２ｂは制御部６で制御されて、それぞれ、第１出力系統の治療波の周波数αと第２出力系統の治療波の周波数βを発生する。治療波は周波数情報だけでなく、周波数をどのようなパターンで変化させるかによって、波形情報を与えることができる。波形情報とは、正弦波や矩形波のように、治療波の波形であり、内部干渉波や生体で発生する干渉低周波の波形と周波数を規定する。ここでは治療波は正弦波の例を述べているが、この場合、例えば治療波の周波数を、経時的に、直線状に増加しその後減少させる（三角波状に変化させる）と、正弦波状の治療波を発生させることができる。また、期間Ｔだけ治療波の周波数をα又はβにして、その後治療波の周波数をゼロにする（パルス状に変化させる）と、パルス状の治療波とすることができる。α又はβを一定に保つと、周期がα又はβの正弦波状の干渉低周波が得られる。位相制御をおこなうと、周波数制御と同様、干渉低周波の波形及び周波数を制御することができる。 The operation of the present invention will be described below based on the block diagram of FIG. 1 and the explanatory diagram of the interference low frequency example of FIG.
The controller 6 includes a carrier wave generator 1, therapeutic wave generators 2a and 2b, frequency converters 3a and 3b, adders 4a and 4b, amplifiers 5a and 5b, regulators 7a and 7b, and not shown in the figure. The input of the operation unit of the apparatus is read, and the entire apparatus including the display unit is controlled accordingly.
The carrier wave generator 1 is controlled by the controller 6 to generate a carrier wave having a predetermined frequency f. The frequency of the carrier wave can be controlled to a set value, but may be fixed.
The treatment wave generators 2a and 2b are controlled by the control unit 6 to generate a treatment wave frequency α of the first output system and a treatment wave frequency β of the second output system, respectively. In the treatment wave, not only frequency information but also waveform information can be given depending on the pattern in which the frequency is changed. The waveform information is a waveform of a therapeutic wave, such as a sine wave or a rectangular wave, and defines a waveform and frequency of an internal interference wave or an interference low frequency generated in a living body. Here, the treatment wave is described as an example of a sine wave. In this case, for example, if the frequency of the treatment wave is increased linearly with time and then decreased (changed to a triangular wave shape), the treatment wave is sinusoidal. Waves can be generated. Further, when the frequency of the treatment wave is set to α or β for the period T and then the frequency of the treatment wave is set to zero (changed in a pulse shape), a pulsed treatment wave can be obtained. When α or β is kept constant, a sinusoidal interference low frequency with a period of α or β is obtained. When the phase control is performed, the waveform and frequency of the interference low frequency can be controlled similarly to the frequency control.

周波数変換器３ａは、搬送波発生部１が発生する周波数ｆの搬送波と、治療波発生器２ａが発生する周波数αの治療波から、周波数ｆ＋αの搬送波を出力する。
周波数変換器３ｂは、搬送波発生部１が発生する周波数ｆの搬送波と、治療波発生器２ｂが発生する周波数βの治療波から、周波数ｆ＋βの搬送波を出力する。
加算器４ａは、搬送波発生部１の出力と周波数変換器３ａの出力を調整器７ａによって調整したものを加算して、周波数がｆの搬送波を含む周波数がαの干渉低周波を発生する。この干渉低周波は装置内部で発生させているため、本発明では内部干渉低周波と称している。周波数αは筋収縮が可能な周波数にしているため、この内部干渉低周波だけでも筋収縮を生じさせることができる。 The frequency converter 3a outputs a carrier wave having a frequency f + α from a carrier wave having a frequency f generated by the carrier wave generator 1 and a treatment wave having a frequency α generated by the treatment wave generator 2a.
The frequency converter 3b outputs a carrier wave having a frequency f + β from a carrier wave having a frequency f generated by the carrier wave generator 1 and a treatment wave having a frequency β generated by the treatment wave generator 2b.
The adder 4a adds the output of the carrier wave generator 1 and the output of the frequency converter 3a adjusted by the adjuster 7a, and generates an interference low frequency having a frequency of α including the carrier wave of frequency f. Since this interference low frequency is generated inside the apparatus, it is referred to as internal interference low frequency in the present invention. Since the frequency α is set to a frequency at which muscle contraction is possible, muscle contraction can be caused only by this low internal interference frequency.

同様に加算器４ｂは、搬送波発生部１の出力と周波数変換器３ｂの出力を調整器７ｂによって調整したものを加算して、周波数がｆの搬送波を含む周波数がβの内部干渉低周波を発生する。この内部干渉低周波でも筋収縮を生じさせることができる。
第１の出力系統と第２の出力系統が発生する内部干渉低周波は、増幅器５ａと５ｂで所望の値に増幅され、電極８と９を介して、生体に供給される。
生体内で、２つの出力系統から出力された２つの内部干渉低周波が干渉し、周波数がｆの搬送波を含む周波数がα−βの干渉低周波が発生する。
その結果、生体は周波数がα−βの生体内で発生する干渉低周波と、第１出力系統が出力する周波数がαの内部干渉低周波と、第２出力系統が発生する周波数がβの内部干渉低周波の、合計３つの干渉低周波で生体を刺激し、筋収縮を生じさせる。 Similarly, the adder 4b adds the output of the carrier wave generator 1 and the output of the frequency converter 3b adjusted by the adjuster 7b, and generates an internal interference low frequency whose frequency is β including the carrier wave of frequency f. To do. Muscle contraction can be caused even by this low frequency of internal interference.
The internal interference low frequency generated by the first output system and the second output system is amplified to a desired value by the amplifiers 5a and 5b, and supplied to the living body through the electrodes 8 and 9.
In the living body, two internal interference low frequencies output from the two output systems interfere with each other, and an interference low frequency having a frequency of α-β including a carrier wave having a frequency f is generated.
As a result, the living body has an interference low frequency generated in the living body having the frequency α-β, an internal interference low frequency output by the first output system is α, and a frequency generated by the second output system is the inside of β. The living body is stimulated by a total of three interference low frequencies of interference low frequency, and muscle contraction is caused.

本発明の請求項２に係る発明の一実施例について以下に説明する。
１個の干渉低周波で治療していた特許文献１のような干渉低周波治療器と比し、本発明の干渉低周波治療器によると、より複雑な刺激をおこなうことができるので、慣れがより少なくなり、治療効果も向上する。
３つの干渉低周波で治療する点は特許文献２と同じであり、同等の治療効果を有する。しかし、本発明では２組の電極でよいが、特許文献２は３組の電極を必要とする。手足のように小さな部位では電極を３組貼るスペースがない場合もある。このような部位では効果の劣る特許文献１のような干渉低周波を使用する以外に無いため、効果の劣る治療をおこなわざるを得ない。しかし本発明では２組の電極で済むため、小さな部位でも特許文献２と同等の高い治療をおこなうことができる。 An embodiment of the invention according to claim 2 of the present invention will be described below.
Compared with the interference low-frequency treatment device as in Patent Document 1 treated with a single interference low-frequency, the interference low-frequency treatment device of the present invention can perform more complex stimulation, so It becomes less and the therapeutic effect is improved.
The point of treatment with three interference low frequencies is the same as in Patent Document 2 and has the same therapeutic effect. However, in the present invention, two sets of electrodes may be used, but Patent Document 2 requires three sets of electrodes. There may be no space for three sets of electrodes in a small region such as a limb. In such a part, since there is no use other than using an interference low frequency like Patent Document 1 which is inferior in effectiveness, treatment with inferior effect must be performed. However, in the present invention, since only two sets of electrodes are required, even a small portion can be treated as highly as in Patent Document 2.

本発明の請求項３に係る発明の一実施例について以下に説明する。
以上の説明では、変換器３ａ及び３ｂに周波数変換器を用いた例を述べた。しかし本発明は、変換器３ａ及び３ｂに位相器を使用してもよい。
この場合、治療波発生器で作成したパターン（治療波の波形と周波数）によって位相器を制御し、搬送波発生部１が発生する周波数ｆの搬送波の位相を制御する。この位相器出力と搬送波発生部１の出力を加算器で加算すると、やはり、周波数がαとβの内部干渉低周波を発生させることができる。 An embodiment of the invention according to claim 3 of the present invention will be described below.
In the above description, the example which used the frequency converter for the converters 3a and 3b was described. However, the present invention may use a phase shifter for the converters 3a and 3b.
In this case, the phase shifter is controlled by a pattern (the waveform and frequency of the treatment wave) created by the treatment wave generator, and the phase of the carrier wave having the frequency f generated by the carrier wave generator 1 is controlled. When the output of the phase shifter and the output of the carrier wave generator 1 are added by an adder, an internal interference low frequency having frequencies α and β can be generated.

出力系統を４個以上にすると、より多くの干渉低周波で、より複雑な、新しい刺激感の、よりなれの少ない、より効果的な筋刺激をおこなうことができる。
また、本発明では、搬送波の周波数を制御できる。搬送波の周波数が例えば１ｋＨｚ程度から１０ｋＨｚ程度まで変化すると、それぞれの周波数領域で筋収縮力も異なるし、電気刺激感も異なり、周波数の変化を識別することができる。このため、搬送波の周波数を大きく変化させると、それだけで目新しい刺激となり、慣れを防止できる。 When the number of output systems is four or more, more effective muscle stimulation can be performed with more interference and lower frequency, more complex, new stimulation feeling, less familiarity, and more.
In the present invention, the frequency of the carrier wave can be controlled. When the frequency of the carrier wave changes from about 1 kHz to about 10 kHz, for example, the muscle contraction force is different in each frequency region, and the electric stimulation feeling is also different, so that the change in frequency can be identified. For this reason, if the frequency of the carrier wave is changed greatly, it will become a novel stimulus by itself and prevent habituation.

さらに、本発明では、治療波発生器で任意の波形と周波数情報を有する情報を出力することができる。このため、内部干渉低周波の波形と周波数、及び生体内で発生する干渉低周波の波形と周波数を任意に設定でき、しかも、干渉低周波の波形と周波数を経時的に変化させることも可能である。通常、従来の干渉低周波治療器では、正弦波状の干渉低周波や、矩形のバースト波を発生させていた。しかし、本発明では、任意の波形のパルス状の干渉低周波を得ることができるので、神経刺激に適した細いパルスや、創傷治癒促進に適した幅の広いパルスなど、目的に応じた波形の干渉低周波を出力することができる。さらに、搬送波の周波数を変化させると、搬送波の周波数帯による刺激感覚の違いも知覚でき、より変化に富んだ刺激が可能になる。    Furthermore, in this invention, the information which has arbitrary waveforms and frequency information can be output with a therapeutic wave generator. Therefore, the internal interference low frequency waveform and frequency, and the interference low frequency waveform and frequency generated in the living body can be set arbitrarily, and the interference low frequency waveform and frequency can be changed over time. is there. Usually, conventional interference low frequency treatment devices generate sinusoidal interference low frequency and rectangular burst waves. However, in the present invention, a pulse-like interference low frequency having an arbitrary waveform can be obtained. Interference low frequency can be output. Furthermore, if the frequency of the carrier wave is changed, a difference in stimulation sensation depending on the frequency band of the carrier wave can be perceived, and stimulation with more variety is possible.
