　本発明は、低周波治療器、制御方法、及び制御プログラムに関する。 The present invention relates to a low frequency treatment device, a control method, and a control program.
　従来、導電層を有するパッドをユーザの身体に取り付けて、身体に低周波パルス電流を供給することで、ユーザの肩こりをほぐす等の治療を行う低周波治療器が知られている。 Conventionally, there is known a low-frequency treatment device that performs treatment such as loosening a user's stiff shoulder by attaching a pad having a conductive layer to the user's body and supplying a low-frequency pulse current to the body.

　低周波パルス電流による、肩こりをほぐす等の治療の効果は認められているものの、その治療の効果はユーザの状態にも左右される。例えば、座位又は臥位のような安静状態で脱力し、視覚や聴覚に依存しない状態であることが、低周波パルス電流による治療の効果の向上に有効であると考えられる。 Although the effect of treatment such as relieving stiff shoulders by low frequency pulse current has been recognized, the effect of the treatment depends on the user's condition. For example, it is considered that a state of weakness in a resting state such as a sitting position or a lying position and a state that does not depend on sight or hearing is effective in improving the effect of treatment by a low frequency pulse current.
　しかしながら、従来の技術においては、低周波パルス電流による治療の進行状態が、画面表示や音などで通知されるため、治療の進行状態が気になるユーザの注意は視覚や聴覚に向いてしまう。このため、低周波パルス電流による治療中のユーザを、視覚や聴覚に依存しない状態、すなわち治療に適した状態に導くことは困難という課題があった。 However, in the conventional technology, since the progress state of the treatment by the low frequency pulse current is notified by the screen display or the sound, the attention of the user who is concerned about the progress state of the treatment is directed to the visual sense and the auditory sense. Therefore, there is a problem that it is difficult to lead a user who is being treated with a low-frequency pulse current to a state that does not depend on sight or hearing, that is, a state suitable for treatment.
　また、画面表示や音などによる通知を行うと、光や音を出すことが望ましくない場所で低周波パルス電流による治療を行うことができないという課題や、ユーザが他のものを見ていたり他の音を聞いていたりしているときに通知内容を把握しにくいという課題や、ユーザの目や耳が不自由であると通知内容を把握しにくいという課題もある。 In addition, when notification is given by screen display or sound, there is a problem that treatment with low frequency pulse current cannot be performed in places where it is not desirable to emit light or sound, and the user is looking at other things or other things. There is also a problem that it is difficult to grasp the notification content when listening to a sound, and a problem that it is difficult to grasp the notification content when the user's eyes and ears are deaf.
　また、これらの課題を解決するための手段は、特許文献１，２にも開示されていない。 Further, the means for solving these problems is not disclosed in Patent Documents 1 and 2.
　本発明は、一側面では、このような実情を鑑みてなされたものであり、その目的は、治療中のユーザを治療に適した状態に導くことができる技術を提供することである。 The present invention, on the one hand, has been made in view of such circumstances, and an object of the present invention is to provide a technique capable of leading a user under treatment to a state suitable for treatment.
　本発明は、上記の課題を解決するために、以下の構成を採用する。 The present invention adopts the following configuration in order to solve the above problems.
　すなわち、本発明の一側面に係る低周波治療器は、接触対象にパルス電流を供給可能なパッド部と、治療用の電気的刺激を与える低周波パルス電流を前記パッド部から供給させと、前記治療用の電気的刺激とは異なる皮膚もしくは筋肉への刺激により、治療の進行に関する通知を行う制御部と、を備える。 That is, in the low-frequency treatment device according to one aspect of the present invention, a pad portion capable of supplying a pulse current to a contact target and a low-frequency pulse current that gives an electrical stimulus for treatment are supplied from the pad portion. It is provided with a control unit for notifying the progress of treatment by stimulating the skin or muscle different from the electrical stimulation for treatment.
　上記構成では、治療用の電気的刺激を与える低周波パルス電流の供給に加えて、治療用の電気的刺激とは異なる、電気、振動、温度、加圧等による皮膚もしくは筋肉への刺激により治療の進行に関する通知が行われるため、ユーザは、治療用の低周波パルス電流と区別して、治療の進行に関する通知を知覚することができる。これにより、ユーザは、視覚や聴覚によらずに、低周波パルス電流による治療の進行を把握することができる。このため、ユーザを、視覚や聴覚に依存しない状態、すなわち治療に適した状態に導くことが可能になる。 In the above configuration, in addition to supplying a low-frequency pulse current that gives a therapeutic electrical stimulus, the treatment is performed by stimulating the skin or muscle with electricity, vibration, temperature, pressurization, etc., which is different from the therapeutic electrical stimulus. Since the notification regarding the progress of the treatment is performed, the user can perceive the notification regarding the progress of the treatment separately from the low frequency pulse current for the treatment. As a result, the user can grasp the progress of the treatment by the low frequency pulse current regardless of the visual sense or the auditory sense. Therefore, it is possible to lead the user to a state that does not depend on sight or hearing, that is, a state suitable for treatment.
　前記制御部は、前記パッド部から、前記治療用の電気的刺激を与える低周波パルス電流と、前記治療用の電気的刺激とは異なる、治療の進行に関する通知を行う電気的刺激を与える通知用パルス電流と、を供給させる制御を行ってもよい。当該構成によれば、ユーザは、治療用の低周波パルス電流と区別して通知用パルス電流を知覚することができる。 The control unit is used for notification from the pad unit to give a low-frequency pulse current that gives an electrical stimulus for the treatment and an electrical stimulus that gives a notification regarding the progress of the treatment, which is different from the electrical stimulus for the treatment. Control may be performed to supply the pulse current. According to this configuration, the user can perceive the notification pulse current separately from the therapeutic low frequency pulse current.
　上記一側面に係る低周波治療器において、前記通知用パルス電流は、前記低周波パルス電流のパルス幅と異なるパルス幅を有するパルス電流であってもよい。当該構成によれば、ユーザが通知用パルス電流を低周波パルス電流と区別して知覚することができる。 In the low frequency treatment device according to the above aspect, the notification pulse current may be a pulse current having a pulse width different from the pulse width of the low frequency pulse current. According to this configuration, the user can perceive the notification pulse current separately from the low frequency pulse current.
　上記一側面に係る低周波治療器において、前記通知用パルス電流は、前記低周波パルス電流のパルス幅と異なる振幅を有するパルス電流であってもよい。当該構成によれば、ユーザが通知用パルス電流を低周波パルス電流と区別して知覚することができる。 In the low frequency treatment device according to the above aspect, the notification pulse current may be a pulse current having an amplitude different from the pulse width of the low frequency pulse current. According to this configuration, the user can perceive the notification pulse current separately from the low frequency pulse current.
　上記一側面に係る低周波治療器において、前記通知用パルス電流は、前記低周波パルス電流の周期と異なる周期を有するパルス電流であってもよい。当該構成によれば、ユーザが通知用パルス電流を低周波パルス電流と区別して知覚することができる。 In the low frequency treatment device according to the above aspect, the notification pulse current may be a pulse current having a cycle different from the cycle of the low frequency pulse current. According to this configuration, the user can perceive the notification pulse current separately from the low frequency pulse current.
　上記一側面に係る低周波治療器において、前記制御部は、前記低周波パルス電流の供給開始からの経過時間に基づいて前記通知用パルス電流を供給してもよい。当該構成によれば、治療開始からの経過時間に応じた治療の進行状態をユーザに通知することができる。 In the low frequency treatment device according to the one aspect, the control unit may supply the notification pulse current based on the elapsed time from the start of supply of the low frequency pulse current. According to this configuration, it is possible to notify the user of the progress state of the treatment according to the elapsed time from the start of the treatment.
　上記一側面に係る低周波治療器において、前記制御部は、治療用の電気的刺激を与える複数種類の低周波パルス電流を切り替えて前記パッド部から供給させ、供給させる前記低周波パルス電流の切り替わりに基づいて前記通知用パルス電流を供給してもよい。当該構成によれば、治療の進行に伴う治療内容の変化をユーザに通知することができる。 In the low-frequency treatment device according to the above aspect, the control unit switches a plurality of types of low-frequency pulse currents that give electrical stimulation for treatment, supplies the pads, and switches the low-frequency pulse currents to be supplied. The notification pulse current may be supplied based on the above. According to this configuration, it is possible to notify the user of changes in the treatment content as the treatment progresses.
　上記一側面に係る低周波治療器において、前記制御部は、前記低周波パルス電流の供給予定タイミングと前記通知用パルス電流の供給予定タイミングとが重なった場合に、当該低周波パルス電流の供給タイミングをずらしてもよい。当該構成によれば、低周波パルス電流の供給タイミングと通知用パルス電流の供給タイミングとが重ならないようにし、ユーザに対して通知用パルス電流を確実に知覚させることができる。 In the low-frequency treatment device according to the above aspect, the control unit receives the low-frequency pulse current supply timing when the low-frequency pulse current supply scheduled timing and the notification pulse current supply scheduled timing overlap. May be shifted. According to this configuration, the supply timing of the low-frequency pulse current and the supply timing of the notification pulse current do not overlap, and the user can be surely perceived the notification pulse current.
　上記一側面に係る低周波治療器において、前記制御部は、前記低周波パルス電流の供給予定タイミングと前記通知用パルス電流の供給予定タイミングとが重なった場合に、当該低周波パルス電流の振幅を縮小し、又は当該低周波パルス電流を供給しない。当該構成によれば、通知用パルス電流が、低周波パルス電流によって知覚できなくなることを抑制することができる。このため、低周波パルス電流の供給への影響を抑制しつつ、通知用パルス電流８５をユーザに知覚させることができる。 In the low-frequency treatment device according to the above aspect, the control unit determines the amplitude of the low-frequency pulse current when the scheduled supply timing of the low-frequency pulse current and the scheduled supply timing of the notification pulse current overlap. Do not reduce or supply the low frequency pulse current. According to this configuration, it is possible to prevent the notification pulse current from becoming imperceptible due to the low frequency pulse current. Therefore, the user can perceive the notification pulse current 85 while suppressing the influence on the supply of the low frequency pulse current.
　上記一側面に係る低周波治療器において、前記制御部は、前記低周波パルス電流の供給予定タイミングと前記通知用パルス電流の供給予定タイミングとが重なった場合に、通知用パルス電流の供給タイミングをずらしてもよい。当該構成によれば、低周波パルス電流の供給タイミングと通知用パルス電流の供給タイミングとが重ならないようにし、低周波パルス電流の供給への影響を抑制しつつ、ユーザに対して通知用パルス電流を確実に知覚させることができる。 In the low-frequency treatment device according to the above aspect, the control unit determines the supply timing of the notification pulse current when the scheduled supply timing of the low-frequency pulse current and the scheduled supply timing of the notification pulse current overlap. You may shift it. According to this configuration, the supply timing of the low-frequency pulse current and the supply timing of the notification pulse current do not overlap, and the influence on the supply of the low-frequency pulse current is suppressed, while the notification pulse current is notified to the user. Can be surely perceived.

　以下、本発明の一側面に係る実施の形態を、図面に基づいて説明する。 Hereinafter, embodiments according to one aspect of the present invention will be described with reference to the drawings.
＜適用例＞
　図１は、本発明の適用例である低周波治療器１０を示す図である。 <Application example>
FIG. 1 is a diagram showing a low frequency treatment device 10 which is an application example of the present invention.
　低周波治療器１０は、ユーザに対して低周波パルス電流を供給して電気的な刺激を与えることにより、ユーザの治療等を行うための装置である。低周波パルス電流の周波数は、例えば１～１２００［Ｈｚ］程度である。低周波治療器１０は、パッド部１１と、制御部１２と、を備える。 The low frequency treatment device 10 is a device for treating a user or the like by supplying a low frequency pulse current to the user and giving an electrical stimulus. The frequency of the low frequency pulse current is, for example, about 1 to 1200 [Hz]. The low frequency treatment device 10 includes a pad unit 11 and a control unit 12.
　パッド部１１は、ユーザの身体に取り付け可能である。また、パッド部１１は、取り付け先（接触対象）であるユーザの身体に対してパルス電流を供給可能である。パッド部１１によるパルス電流の供給は、制御部１２によって制御される。 The pad portion 11 can be attached to the user's body. Further, the pad portion 11 can supply a pulse current to the body of the user who is the attachment destination (contact target). The supply of the pulse current by the pad unit 11 is controlled by the control unit 12.
　制御部１２は、パッド部１１から、治療用の電気的刺激を与えるための低周波パルス電流を供給させる制御を行う。また、制御部１２は、低周波パルス電流の供給による治療中に、低周波パルス電流による治療用の電気的刺激とは異なる皮膚もしくは筋肉への刺激により、治療の進行に関する通知を行う。例えば、制御部１２は、パッド部１１から、その治療の進行に関する通知を行うための電気的刺激を与える通知用パルス電流を供給させる制御を行う。 The control unit 12 controls to supply a low-frequency pulse current for giving a therapeutic electrical stimulus from the pad unit 11. Further, the control unit 12 notifies the progress of the treatment by stimulating the skin or muscle different from the electrical stimulus for the treatment by the low frequency pulse current during the treatment by supplying the low frequency pulse current. For example, the control unit 12 controls the pad unit 11 to supply a notification pulse current that gives an electrical stimulus for notifying the progress of the treatment.
　この通知用パルス電流は、治療用の電気的刺激とは異なる電気的刺激を与えるパルス電流である。具体的には、通知用パルス電流は、低周波パルス電流に対して、パルス幅、振幅、及び周期の少なくともいずれかが異なるパルス電流である。 This notification pulse current is a pulse current that gives an electrical stimulus different from the therapeutic electrical stimulus. Specifically, the notification pulse current is a pulse current having at least one of a pulse width, an amplitude, and a period different from that of a low frequency pulse current.
　例えば、通知用パルス電流は、低周波パルス電流のパルス幅より狭いパルス幅を有するパルス電流である。これにより、比較的パルス幅が広い治療用の低周波パルス電流に対して通知用パルス電流を区別して知覚することが容易になる。ただし、通知用パルス電流は、低周波パルス電流のパルス幅より広いパルス幅を有するパルス電流であってもよい。この場合も、ユーザは、治療用の低周波パルス電流に対して通知用パルス電流を区別して知覚することができる。 For example, the notification pulse current is a pulse current having a pulse width narrower than the pulse width of the low frequency pulse current. This makes it easy to distinguish and perceive the notification pulse current as opposed to the therapeutic low frequency pulse current, which has a relatively wide pulse width. However, the notification pulse current may be a pulse current having a pulse width wider than the pulse width of the low frequency pulse current. Again, the user can distinguish and perceive the notification pulse current as opposed to the therapeutic low frequency pulse current.
　また、通知用パルス電流は、低周波パルス電流の振幅より小さい振幅を有するパルス電流であってもよい。これにより、ユーザに過度の負担を与えることを抑制しつつ、低周波パルス電流に対して通知用パルス電流を区別して知覚することが容易になる。ただし、通知用パルス電流は、低周波パルス電流の振幅より大きい振幅を有するパルス電流であってもよい。この場合も、ユーザは、治療用の低周波パルス電流に対して通知用パルス電流を区別して知覚することができる。 Further, the notification pulse current may be a pulse current having an amplitude smaller than the amplitude of the low frequency pulse current. This makes it easy to distinguish and perceive the notification pulse current with respect to the low frequency pulse current while suppressing an excessive burden on the user. However, the notification pulse current may be a pulse current having an amplitude larger than the amplitude of the low frequency pulse current. Again, the user can distinguish and perceive the notification pulse current as opposed to the therapeutic low frequency pulse current.
　また、通知用パルス電流は、低周波パルス電流の周期より短い周期を有する（すなわち高周波の）パルス電流であってもよい。これにより、比較的周期が長い治療用の低周波パルス電流に対して通知用パルス電流を区別して知覚することが容易になる。ただし、通知用パルス電流は、低周波パルス電流の周期より短い周期を有するパルス電流であってもよい。この場合も、ユーザは、治療用の低周波パルス電流に対して通知用パルス電流を区別して知覚することができる。 Further, the notification pulse current may be a pulse current having a period shorter than the period of the low frequency pulse current (that is, a high frequency pulse current). This makes it easy to distinguish and perceive the notification pulse current as opposed to the therapeutic low frequency pulse current, which has a relatively long period. However, the notification pulse current may be a pulse current having a period shorter than the period of the low frequency pulse current. Again, the user can distinguish and perceive the notification pulse current as opposed to the therapeutic low frequency pulse current.
　また、制御部１２は、例えば、低周波パルス電流の供給開始からの経過時間に基づいて、通知用パルス電流をパッド部２から供給させる。これにより、治療開始からの経過時間に応じた治療の進行状態をユーザに通知することができる。治療開始からの経過時間に応じた治療の進行状態とは、例えば、治療開始からの経過時間、又は、一定の長さを有する治療の終了までの残り時間などである。 Further, the control unit 12 supplies the notification pulse current from the pad unit 2, for example, based on the elapsed time from the start of supply of the low frequency pulse current. As a result, it is possible to notify the user of the progress state of the treatment according to the elapsed time from the start of the treatment. The progress state of the treatment according to the elapsed time from the start of the treatment is, for example, the elapsed time from the start of the treatment or the remaining time until the end of the treatment having a certain length.
　また、治療開始からの経過時間に応じた治療の進行状態は、治療の終了や、治療の終了後から一定時間以上が経過した状態などであってもよい。これにより、ユーザは、治療が終了したことを認識することができ、ユーザが治療の終了に気付かずにパッド２１を装着したままになったり、その状態で寝てしまったりすることを抑制することができる。 Further, the progress state of the treatment according to the elapsed time from the start of the treatment may be a state in which a certain time or more has passed since the end of the treatment or the end of the treatment. As a result, the user can recognize that the treatment has ended, and suppresses the user from staying on the pad 21 or falling asleep in that state without noticing the end of the treatment. Can be done.
　また、制御部１２は、治療用の電気的刺激を与える複数種類の低周波パルス電流を切り替えてパッド部２から供給させ、供給する低周波パルス電流の切り替わりに基づいて通知用パルス電流を供給してもよい。これにより、低周波パルス電流の切り替わりによる治療内容の変化をユーザに通知することができる。低周波パルス電流の切り替わりは、予め定められた時間の経過によって自動的に行われるものであってもよいし、ユーザ操作に応じた切り替わりであってもよい。 Further, the control unit 12 switches a plurality of types of low-frequency pulse currents that give electrical stimulation for treatment and supplies them from the pad unit 2, and supplies a notification pulse current based on the switching of the supplied low-frequency pulse currents. You may. As a result, it is possible to notify the user of the change in the treatment content due to the switching of the low frequency pulse current. The switching of the low-frequency pulse current may be automatically performed with the passage of a predetermined time, or may be switched according to the user's operation.
　このように、低周波治療器１０は、治療用の電気的刺激を与える低周波パルス電流に加えて、治療の進行に関する通知を行う電気的刺激を与える通知用パルス電流をユーザに供給する。これにより、ユーザは、治療用の低周波パルス電流と区別して通知用パルス電流を知覚し、視覚や聴覚によらずに、低周波パルス電流による治療の進行を把握することができる。このため、ユーザを、視覚や聴覚に依存しない状態、すなわち治療に適した状態に導くことが可能になる。ユーザを治療に適した状態に導くことにより、低周波パルス電流による治療の効果の向上を図ることができる。 As described above, the low-frequency treatment device 10 supplies the user with a notification pulse current that gives an electrical stimulus for notifying the progress of the treatment, in addition to the low-frequency pulse current that gives an electrical stimulus for the treatment. As a result, the user can perceive the notification pulse current separately from the low-frequency pulse current for treatment, and can grasp the progress of the treatment by the low-frequency pulse current regardless of visual or auditory sense. Therefore, it is possible to lead the user to a state that does not depend on sight or hearing, that is, a state suitable for treatment. By guiding the user to a state suitable for treatment, it is possible to improve the effect of treatment by the low frequency pulse current.
　例えば、ユーザは、目を閉じてリラックスした状態でも、低周波治療を開始してからどれくらい時間が経ったか、低周波治療があとどれくらいで終了するか、又は一連の低周波治療がどの段階まで進んだか、などの低周波治療の進行状態を把握することができる。 For example, a user may have closed his eyes and relaxed, how long has passed since the start of the low frequency treatment, how soon the low frequency treatment will end, or how far the series of low frequency treatments has progressed. However, it is possible to grasp the progress of low-frequency treatment such as.
　さらに、低周波治療器１０は、低周波パルス電流の供給予定タイミングと通知用パルス電流の供給予定タイミングとが重なった場合に、通知用パルス電流の知覚が困難になることを抑制する制御を行ってもよい。この制御については後述する（例えば図１０～図１２参照）。 Further, the low-frequency treatment device 10 controls to suppress difficulty in perceiving the notification pulse current when the scheduled supply timing of the low-frequency pulse current and the scheduled supply timing of the notification pulse current overlap. You may. This control will be described later (see, for example, FIGS. 10 to 12).
＜低周波治療器１０の一例である低周波治療器２０の構成＞
　図２は、低周波治療器１０の一例である低周波治療器２０の構成を示す斜視図である。図３は、低周波治療器２０におけるパッド部２と本体部３とを分離した状態を示す分解斜視図である。図４は、低周波治療器２０におけるパッド部２を示す平面図である。図５は、低周波治療器２０におけるパッド部２を示す底面図である。 <Structure of the low frequency treatment device 20 which is an example of the low frequency treatment device 10>
FIG. 2 is a perspective view showing the configuration of the low frequency treatment device 20 which is an example of the low frequency treatment device 10. FIG. 3 is an exploded perspective view showing a state in which the pad portion 2 and the main body portion 3 of the low frequency treatment device 20 are separated. FIG. 4 is a plan view showing the pad portion 2 in the low frequency treatment device 20. FIG. 5 is a bottom view showing the pad portion 2 of the low frequency treatment device 20.
　低周波治療器２０は、コードレスタイプの低周波治療器であり、パッド部２及び本体部３を備える。パッド部２は、図１に示したパッド部１１の一例である。本体部３は、図１に示した制御部１２の一例である。 The low frequency treatment device 20 is a cordless type low frequency treatment device, and includes a pad portion 2 and a main body portion 3. The pad portion 2 is an example of the pad portion 11 shown in FIG. The main body 3 is an example of the control unit 12 shown in FIG.
　パッド部２は、パッド２１及びホルダ２２により構成されている。パッド２１及びホルダ２２は、この例では一体になっている。「一体」とは、通常の使用状態でパッド２１とホルダ２２とが互いに分離不能に組み合わされた状態をいう。ただし、パッド２１及びホルダ２２は、互いに分離可能になっていてもよい。 The pad portion 2 is composed of a pad 21 and a holder 22. The pad 21 and the holder 22 are integrated in this example. "Integral" means a state in which the pad 21 and the holder 22 are inseparably combined with each other in a normal use state. However, the pad 21 and the holder 22 may be separable from each other.
　パッド２１は、ユーザの身体に取り付けられる部分である。このパッド２１は、ユーザに低周波パルス電流を供給する導電層２１ａを備える。導電層２１ａはパッド２１の表裏各面の少なくとも一部に露出している。この例では、パッド２１におけるユーザの身体側を向いた裏面２１１の全面と、パッド２１における表面の一部と、に導電層２１ａが露出している。 The pad 21 is a part attached to the user's body. The pad 21 includes a conductive layer 21a that supplies a low frequency pulse current to the user. The conductive layer 21a is exposed on at least a part of the front and back surfaces of the pad 21. In this example, the conductive layer 21a is exposed on the entire surface of the back surface 211 of the pad 21 facing the user's body side and a part of the surface surface of the pad 21.
　ユーザの身体へのパッド２１の取り付けは、パッド２１の裏面２１１を、図５にハッチングを付して示した範囲の治療部２１Ｙに取り付けられた導電性のゲルを介してユーザの皮膚に貼り付けることにより行われる。 To attach the pad 21 to the user's body, the back surface 211 of the pad 21 is attached to the user's skin via a conductive gel attached to the treatment unit 21Y in the range shown with hatching in FIG. It is done by.
　パッド２１は、例えば、軟質合成樹脂製の基材の表面に、印刷により導体であるカーボン層を積層したものであり、このカーボン層が導電層２１ａとなる。パッド２１は可撓性を有する。導電層２１ａは、通電時の極性（＋極と－極）別に設けられている。なお、パッド２１には極性を交互に転換させて通電することもあるので、＋極専用の導電層２１ａと－極専用の導電層２１ａが固定的に存在するのではなく、極性は可変的である。 The pad 21 is, for example, a carbon layer as a conductor laminated on the surface of a base material made of a soft synthetic resin by printing, and this carbon layer serves as a conductive layer 21a. The pad 21 has flexibility. The conductive layer 21a is provided for each polarity (+ pole and-pole) when energized. Since the pad 21 may be energized by alternately changing the polarity, the conductive layer 21a dedicated to the + pole and the conductive layer 21a dedicated to the-pole are not fixedly present, but the polarity is variable. be.
　例えば、図３に示すように、パッド２１は、ホルダ２２上に取り付けられる取付部２１Ｘと、この取付部２１Ｘから少なくとも一方に延び導電層２１ａが露出した治療部２１Ｙと、を備える。 For example, as shown in FIG. 3, the pad 21 includes a mounting portion 21X mounted on the holder 22, and a treatment portion 21Y extending from the mounting portion 21X in at least one direction and exposing the conductive layer 21a.
　導電層２１ａは、パッド２１の取付部２１Ｘにおける本体部３を向いた面である表面にも露出しており、この露出部分がパッド側電極部２１２となる。このパッド側電極部２１２は、本体部３の電極（不図示）との電気的接続のために形成されている。 The conductive layer 21a is also exposed on the surface of the mounting portion 21X of the pad 21 facing the main body portion 3, and this exposed portion serves as the pad side electrode portion 212. The pad-side electrode portion 212 is formed for electrical connection with an electrode (not shown) of the main body portion 3.
　この例では、取付部２１Ｘにおける幅方向（図４における上下方向）の一端に一方の極（例えば＋極）に対応した導電層２１ａが露出し、他端に他方の極（例えば－極）に対応した導電層２１ａが露出している。 In this example, the conductive layer 21a corresponding to one pole (for example, + pole) is exposed at one end in the width direction (vertical direction in FIG. 4) of the mounting portion 21X, and the other pole (for example, − pole) is exposed at the other end. The corresponding conductive layer 21a is exposed.
　ホルダ２２は、パッド２１を保持する部分である。この例では、ホルダ２２は、硬質樹脂製であり、両面粘着テープによりパッド２１の取付部２１Ｘを保持している。これにより、パッド２１とホルダ２２とが一体とされる。 The holder 22 is a portion that holds the pad 21. In this example, the holder 22 is made of hard resin and holds the mounting portion 21X of the pad 21 by the double-sided adhesive tape. As a result, the pad 21 and the holder 22 are integrated.
　このホルダ２２は、パッド２１の取付部２１Ｘを保持するパッド保持部２２１と、パッド保持部２２１の両端に位置する壁部２２２とを備える。なお、パッド２１の保持は、両面粘着テープを用いる方法に限定されず、例えば熱溶着を用いる方法や、のりや接着剤を用いる方法でもよい。 This holder 22 includes a pad holding portion 221 that holds the mounting portion 21X of the pad 21, and wall portions 222 located at both ends of the pad holding portion 221. The holding of the pad 21 is not limited to the method using the double-sided adhesive tape, and may be, for example, a method using heat welding or a method using glue or an adhesive.
　ホルダ２２は硬質樹脂製であるため不導体である。このため、パッド２１をユーザの背中において背骨を跨ぐように配置した場合、背骨に不導体であるホルダ２２を一致させ、パッド２１の治療部２１Ｙが背骨に重ならないように配置できる。 The holder 22 is made of hard resin and is therefore non-conductor. Therefore, when the pad 21 is arranged so as to straddle the spine on the back of the user, the holder 22 which is a non-conductor can be aligned with the spine, and the treatment portion 21Y of the pad 21 can be arranged so as not to overlap the spine.
　これにより、ユーザの背骨及び脊髄に低周波パルス電流が流れることを抑制できる。よって、背骨及び脊髄が電流により損傷を受けることを抑制し、低周波治療器２０を安全に使用できる。また、パッド２１の取付部２１Ｘにおいて、背骨に重なる部分を別途絶縁部材で覆う必要がないため、パッド部２の構成を簡素化できる。 This makes it possible to suppress the flow of low-frequency pulse currents to the user's spine and spinal cord. Therefore, the spine and spinal cord can be prevented from being damaged by the electric current, and the low frequency treatment device 20 can be used safely. Further, in the mounting portion 21X of the pad 21, it is not necessary to separately cover the portion overlapping the spine with an insulating member, so that the configuration of the pad portion 2 can be simplified.
　パッド２１は、消耗品であり、交換の際などに本体部３に対して着脱可能とされている。この例では、ホルダ２２がパッド２１と一体となってパッド部２を構成しており、ホルダ２２に対して本体部３を着脱するよう構成されている。パッド２１の交換は、例えばホルダ２２ごと行われる。 The pad 21 is a consumable item and can be attached to and detached from the main body 3 when it is replaced. In this example, the holder 22 is integrated with the pad 21 to form the pad portion 2, and the main body portion 3 is attached to and detached from the holder 22. The pad 21 is replaced, for example, for each holder 22.
　本体部３は、ホルダ２２に取り付けられることで、パッド２１の導電層２１ａに低周波パルス電流を印加する部分である。本体部３の内部には電池等の電源部、及び、所望の低周波パルス電流を形成するための電気回路（基板）が配置され、外部にはスイッチ類や表示部が設けられていてもよい。 The main body 3 is a portion that is attached to the holder 22 to apply a low frequency pulse current to the conductive layer 21a of the pad 21. A power supply unit such as a battery and an electric circuit (board) for forming a desired low-frequency pulse current may be arranged inside the main body unit 3, and switches and a display unit may be provided outside. ..
　図示を省略するが、本体部３のホルダ２２に正対する下面からは、パッド部２のパッド側電極部２１２と電気的に接続する電極が突出している。この本体部３の電極は極性別に設けられる。 Although not shown, an electrode electrically connected to the pad-side electrode portion 212 of the pad portion 2 protrudes from the lower surface of the main body portion 3 facing the holder 22. The electrodes of the main body 3 are provided according to the polarity.
　ここで、図５に示すように、ホルダ２２が本体部３に係止された状態において、ホルダ２２の幅寸法Ｗ２２は、本体部３の幅寸法Ｗ３よりも小さく形成されている。ホルダ２２は硬質樹脂製であるため可撓性に乏しい。一方、パッド２１は可撓性を有するため、ホルダ２２を本体部３よりも幅狭とすることにより、パッド２１の可撓性が本体部３によって阻害されにくい。このため、使用者の身体の曲面にパッド２１を沿わせやすいから、パッド部２の使用者の身体へのフィット性が良好である。 Here, as shown in FIG. 5, in a state where the holder 22 is locked to the main body portion 3, the width dimension W22 of the holder 22 is formed to be smaller than the width dimension W3 of the main body portion 3. Since the holder 22 is made of hard resin, it lacks flexibility. On the other hand, since the pad 21 has flexibility, the flexibility of the pad 21 is less likely to be hindered by the main body 3 by making the holder 22 narrower than the main body 3. Therefore, since the pad 21 can be easily aligned with the curved surface of the user's body, the fit of the pad portion 2 to the user's body is good.
＜本体部３のハードウェア構成＞
　図６は、本体部３のハードウェア構成の一例を示すブロック図である。本体部３は、例えば、図６に示すように、プロセッサ６１と、メモリ６２と、ユーザインタフェース６３と、電源部６４と、パッド駆動部６５と、を含む。 <Hardware configuration of main unit 3>
FIG. 6 is a block diagram showing an example of the hardware configuration of the main body 3. As shown in FIG. 6, the main body 3 includes, for example, a processor 61, a memory 62, a user interface 63, a power supply unit 64, and a pad drive unit 65.
　プロセッサ６１は、例えば、ＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）やＭＰＵ（Ｍｉｃｒｏ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）などのプロセッサである。プロセッサ６１は、メモリ６２に記憶されたプログラムを読み出して実行することで、低周波治療器２０の各部の動作を制御する制御部となる。なお、プロセッサ６１は、複数のプロセッサの組み合わせであってもよい。図１に示した制御部１２は、例えばプロセッサ６１により構成される。 The processor 61 is, for example, a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The processor 61 becomes a control unit that controls the operation of each part of the low frequency treatment device 20 by reading and executing the program stored in the memory 62. The processor 61 may be a combination of a plurality of processors. The control unit 12 shown in FIG. 1 is composed of, for example, a processor 61.
　メモリ６２は、ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）、ＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）、フラッシュメモリなどによって実現される。メモリ６２は、プロセッサ６１によって実行されるプログラム、又はプロセッサ６１によって用いられるデータなどを記憶する。 The memory 62 is realized by a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, or the like. The memory 62 stores a program executed by the processor 61, data used by the processor 61, and the like.
　ユーザインタフェース６３は、例えば、ユーザからの操作入力を受け付ける入力デバイスや、ユーザへ情報を出力する出力デバイスなどを含む。入力デバイスは、例えばキーやリモコンなどにより実現することができる。出力デバイスは、例えばディスプレイやスピーカなどにより実現することができる。また、タッチパネルなどによって入力デバイス及び出力デバイスの両方を実現してもよい。ユーザインタフェース６３は、プロセッサ６１によって制御される。 The user interface 63 includes, for example, an input device that accepts operation input from the user, an output device that outputs information to the user, and the like. The input device can be realized by, for example, a key or a remote controller. The output device can be realized by, for example, a display or a speaker. Further, both an input device and an output device may be realized by a touch panel or the like. The user interface 63 is controlled by the processor 61.
　また、本体部３は、ユーザインタフェース６３に代えて、又はユーザインタフェース６３に加えて、通信インタフェースを備えてもよい。通信インタフェースは、無線通信のインタフェースであってもよいし、有線通信のインタフェースであってもよい。本体部３が通信インタフェースを備えることにより、例えば、スマートフォンなどの他の通信装置から本体部３に対してコマンドを送信して本体部３を制御したり、本体部３の情報を他の通信装置へ送信したりすることが可能になる。 Further, the main body 3 may be provided with a communication interface in place of the user interface 63 or in addition to the user interface 63. The communication interface may be a wireless communication interface or a wired communication interface. By providing the main body 3 with a communication interface, for example, a command can be transmitted from another communication device such as a smartphone to the main body 3 to control the main body 3, or information on the main body 3 can be transmitted to another communication device. It will be possible to send to.
　電源部６４は、低周波治療器２０の各構成要素に電力を供給する。電源としては、例えば、アルカリ乾電池、又は、リチウムイオン電池やニッケル水素電池などの二次電池が用いられ、電池電圧を安定化して各構成要素に供給する駆動電圧を生成する。また、電源部６４は、電池に限らず、家庭用電源などから供給される電力を用いて、低周波治療器２０の各構成要素に電力を供給するものであってもよい。 The power supply unit 64 supplies electric power to each component of the low frequency treatment device 20. As the power source, for example, an alkaline dry battery or a secondary battery such as a lithium ion battery or a nickel hydrogen battery is used, and a driving voltage that stabilizes the battery voltage and supplies it to each component is generated. Further, the power supply unit 64 may supply electric power to each component of the low frequency treatment device 20 by using electric power supplied not only from a battery but also from a household power source or the like.
　パッド駆動部６５は、パッド２１にパルス電圧を印加することで、パッド２１によるユーザへの低周波パルス電流の供給を制御する。パッド駆動部６５は、プロセッサ６１によって制御される。図７において、本体部３のパッド駆動部６５がパッド２１に印加するパルス電圧について説明する。 The pad drive unit 65 controls the supply of the low frequency pulse current to the user by the pad 21 by applying a pulse voltage to the pad 21. The pad drive unit 65 is controlled by the processor 61. In FIG. 7, the pulse voltage applied to the pad 21 by the pad drive unit 65 of the main body unit 3 will be described.
＜本体部３がパッド２１に印加するパルス電圧＞
　図７は、本体部３がパッド２１に印加するパルス電圧の一例を示す図である。図７に示すパルス電圧波形７０は、本体部３のパッド駆動部６５がパッド２１に印加するパルス電圧の波形の一例である。 <Pulse voltage applied to the pad 21 by the main body 3>
FIG. 7 is a diagram showing an example of a pulse voltage applied to the pad 21 by the main body portion 3. The pulse voltage waveform 70 shown in FIG. 7 is an example of the waveform of the pulse voltage applied to the pad 21 by the pad drive unit 65 of the main body unit 3.
　パルス電圧波形７０のパラメータは、振幅（電圧）Ｖと、パルス幅Ｗと、パルス周期Ｔ（パルス周波数Ｆ＝１／Ｔ）と、を含む。本体部３は、これらのパラメータのうち少なくとも１つのパラメータを変更することにより、ユーザに対する治療内容を変更できる。 The parameters of the pulse voltage waveform 70 include an amplitude (voltage) V, a pulse width W, and a pulse period T (pulse frequency F = 1 / T). The main body 3 can change the treatment content for the user by changing at least one of these parameters.
　具体的には、本体部３は、電源電圧を所定の電圧に昇圧し、昇圧した電圧を、設定された振幅に対応する電圧に調整する。例えば、本体部３は、ユーザからの指示に従って所定数のレベル（１０段階のレベル）でパルス電圧の振幅Ｖを調整できる。本体部３は、あるレベルの設定入力をユーザから受け付けると、そのレベルに対応する振幅Ｖに基づいて、治療モードに応じた治療波形（パルス波形）を生成し、当該治療波形をパッド２１のパッド側電極部２１２に出力する。 Specifically, the main body 3 boosts the power supply voltage to a predetermined voltage, and adjusts the boosted voltage to a voltage corresponding to the set amplitude. For example, the main body 3 can adjust the amplitude V of the pulse voltage at a predetermined number of levels (10 levels) according to an instruction from the user. When the main body 3 receives a setting input of a certain level from the user, the main body 3 generates a treatment waveform (pulse waveform) according to the treatment mode based on the amplitude V corresponding to the level, and the treatment waveform is used as a pad of the pad 21. Output to the side electrode unit 212.
　低周波治療器２０には、複数の治療モードが予め用意されている。例えば、治療モードとしては、「もみ」、「たたき」、「押し」、「スイープ」モード等が挙げられる。本体部３は、パッド２１に印加するパルス電圧の波形を変化させることにより、各種のモードに対応する電気刺激をパッド２１からユーザに与える。 The low frequency treatment device 20 is prepared in advance with a plurality of treatment modes. For example, examples of the treatment mode include "fir", "tapping", "pushing", and "sweep" modes. The main body 3 gives the user electrical stimulation corresponding to various modes from the pad 21 by changing the waveform of the pulse voltage applied to the pad 21.
　また、本体部３は、治療用の電気的刺激を与える低周波パルス電流に加えて、治療の進行に関する通知を行う電気的刺激を与える通知用パルス電流と、をパッド２１から供給させる制御を行う。例えば、本体部３は、低周波パルス電流を生成するためのパルス電圧と、通知用パルス電流を生成するためのパルス電圧と、をパッド２１に印加する。これらの各パルス電圧は、それぞれ予め定められた波形に基づいて生成される。 Further, the main body 3 controls to supply from the pad 21 a low-frequency pulse current that gives an electrical stimulus for treatment and a notification pulse current that gives a notification about the progress of the treatment. .. For example, the main body 3 applies a pulse voltage for generating a low frequency pulse current and a pulse voltage for generating a notification pulse current to the pad 21. Each of these pulse voltages is generated based on a predetermined waveform.
＜低周波治療器２０が供給する低周波パルス電流及び通知用パルス電流の具体例＞
　図８は、低周波治療器２０が供給する低周波パルス電流及び通知用パルス電流の具体例１を示す図である。図８において、横軸は時間を示し、縦方向はパルス電流の振幅（電圧）を示す。 <Specific examples of the low frequency pulse current and the notification pulse current supplied by the low frequency treatment device 20>
FIG. 8 is a diagram showing a specific example 1 of a low frequency pulse current and a notification pulse current supplied by the low frequency treatment device 20. In FIG. 8, the horizontal axis indicates time, and the vertical direction indicates the amplitude (voltage) of the pulse current.
　例えば、低周波治療器２０は、図８に示す低周波パルス電流８１及び通知用パルス電流８５をパッド２１からユーザに供給させる。低周波パルス電流８１は、治療用の電気的刺激を与えるパルス電流である。また、低周波パルス電流８１は、同一の振幅、パルス幅、及び周期で繰り返すパルス電流である。 For example, the low-frequency treatment device 20 causes the user to supply the low-frequency pulse current 81 and the notification pulse current 85 shown in FIG. 8 from the pad 21. The low frequency pulse current 81 is a pulse current that provides a therapeutic electrical stimulus. Further, the low frequency pulse current 81 is a pulse current that repeats with the same amplitude, pulse width, and period.
　通知用パルス電流８５は、低周波パルス電流８１による治療用の電気的刺激とは異なる、治療の進行に関する通知を行う電気的刺激を与えるパルス電流である。具体的には、通知用パルス電流８５は、低周波パルス電流８１と比べて、振幅が小さく、パルス幅が狭く、周期が短いパルス電流である。また、通知用パルス電流８５は、時間的に隣接する２つの低周波パルス電流８１の間の期間に、２回繰り返すパルス電流である。 The notification pulse current 85 is a pulse current that gives an electrical stimulus for notifying the progress of treatment, which is different from the therapeutic electrical stimulus by the low frequency pulse current 81. Specifically, the notification pulse current 85 is a pulse current having a smaller amplitude, a narrower pulse width, and a shorter cycle than the low-frequency pulse current 81. Further, the notification pulse current 85 is a pulse current that repeats twice in a period between two temporally adjacent low frequency pulse currents 81.
　一例としては、本体部３が、パッド２１に対する電圧の印加を、０．５秒だけオンにし、続いて０．５秒だけオフにし、続いて０．５秒だけオンにすることで、パッド２１から通知用パルス電流８５を供給することができる。 As an example, the main body 3 turns on the voltage applied to the pad 21 for 0.5 seconds, then turns it off for 0.5 seconds, and then turns it on for 0.5 seconds, whereby the pad 21 is turned on. The notification pulse current 85 can be supplied from.
　このように、低周波パルス電流８１に加えて、低周波パルス電流８１とは異なる電気的刺激を与える通知用パルス電流８５を供給することで、ユーザは、通知用パルス電流８５を、低周波パルス電流８１とは異なる電気的刺激として知覚することができる。 In this way, by supplying the notification pulse current 85 that gives an electrical stimulus different from the low frequency pulse current 81 in addition to the low frequency pulse current 81, the user can use the notification pulse current 85 as a low frequency pulse. It can be perceived as an electrical stimulus different from the current 81.
　例えば、低周波治療器２０は、低周波パルス電流８１の供給を開始してからの経過時間に基づいて、低周波パルス電流８１の供給が開始されてから一定の時間（一例としては５分）が経過した時点で通知用パルス電流８５を供給する。これにより、ユーザは、通知用パルス電流８５の知覚により、低周波パルス電流８１による治療の開始から一定の時間が経過したことを、視覚や聴覚によらずに認識することができる。 For example, the low-frequency treatment device 20 has a fixed time (for example, 5 minutes) from the start of supply of the low-frequency pulse current 81 based on the elapsed time from the start of supply of the low-frequency pulse current 81. When the lapse of time, the notification pulse current 85 is supplied. Thereby, the user can recognize that a certain time has elapsed from the start of the treatment with the low frequency pulse current 81 by the perception of the notification pulse current 85, regardless of visual or auditory sense.
　したがって、ユーザは、パッド２１からの電気的刺激に集中し、視覚や聴覚に依存しない状態を維持しながら、治療の進行状態も把握することができる。例えば、ユーザは、目を閉じてしたり、音に注意を向けたりしなくても、治療の進行状態も把握することができる。そして、視覚や聴覚に依存しない状態している状態、すなわち治療に適した状態にユーザを導くことにより、低周波パルス電流による治療の効果の向上を図ることができる。 Therefore, the user can concentrate on the electrical stimulus from the pad 21 and grasp the progress state of the treatment while maintaining the state independent of the visual sense and the auditory sense. For example, the user can also keep track of the progress of treatment without having to close his eyes or pay attention to the sound. Then, by guiding the user to a state that does not depend on sight or hearing, that is, a state suitable for treatment, the effect of treatment by the low frequency pulse current can be improved.
　なお、低周波パルス電流８１の供給を開始してからの経過時間に基づく通知用パルス電流８５の例として、低周波パルス電流８１の供給が開始されてから一定の時間が経過した時点で供給される通知用パルス電流８５について説明したが、このような例に限らない。 As an example of the notification pulse current 85 based on the elapsed time from the start of the supply of the low frequency pulse current 81, the low frequency pulse current 81 is supplied when a certain time has elapsed since the supply of the low frequency pulse current 81 was started. Although the notification pulse current 85 has been described, the present invention is not limited to such an example.
　例えば、低周波治療器２０は、低周波パルス電流８１の供給を開始してからの経過時間に基づいて、低周波パルス電流８１の供給の終了時点から一定の時間（一例としては５分）だけ前の時点で通知用パルス電流８５を供給してもよい。これにより、ユーザは、通知用パルス電流８５の知覚により、通知用パルス電流８５による治療の終了までの残り時間（一例としては５分）を把握することができる。 For example, the low-frequency treatment device 20 has a fixed time (for example, 5 minutes) from the end of the supply of the low-frequency pulse current 81 based on the elapsed time from the start of the supply of the low-frequency pulse current 81. The notification pulse current 85 may be supplied at the previous time point. Thereby, the user can grasp the remaining time (for example, 5 minutes) until the end of the treatment by the notification pulse current 85 by perceiving the notification pulse current 85.
　又は、低周波治療器２０は、低周波パルス電流８１の供給を開始してからの経過時間に基づいて、低周波パルス電流８１の供給を開始してから一定の時間（一例としては５分）毎に通知用パルス電流８５を供給してもよい。 Alternatively, the low-frequency treatment device 20 has a fixed time (for example, 5 minutes) from the start of supply of the low-frequency pulse current 81 based on the elapsed time from the start of supply of the low-frequency pulse current 81. The notification pulse current 85 may be supplied every time.
　図９は、低周波治療器２０が供給する低周波パルス電流及び通知用パルス電流の具体例２を示す図である。 FIG. 9 is a diagram showing specific example 2 of the low frequency pulse current and the notification pulse current supplied by the low frequency treatment device 20.
　図９に示す例では、低周波治療器２０は、期間Ｔ１においては低周波パルス電流８１を繰り返し供給し、期間Ｔ２の後の期間Ｔ２においては低周波パルス電流８２を繰り返し供給する。低周波パルス電流８２は、治療用の電気的刺激を与える、低周波パルス電流８１とは波形が異なるパルス電流である。図９に示す例では、低周波パルス電流８２は、低周波パルス電流８１よりも振幅が大きい波形のパルス電流である。 In the example shown in FIG. 9, the low frequency treatment device 20 repeatedly supplies the low frequency pulse current 81 in the period T1 and repeatedly supplies the low frequency pulse current 82 in the period T2 after the period T2. The low-frequency pulse current 82 is a pulse current having a waveform different from that of the low-frequency pulse current 81, which provides a therapeutic electrical stimulus. In the example shown in FIG. 9, the low-frequency pulse current 82 is a pulse current having a waveform having a larger amplitude than the low-frequency pulse current 81.
　例えば、期間Ｔ１は、比較的弱い電気的刺激を与える弱刺激モードの期間であり、期間Ｔ２は、比較的強い電気的刺激を与える強刺激モードの期間である。そして、低周波治療器２０は、弱刺激モード（期間Ｔ１）の終了後に、強刺激モード(期間Ｔ２)に自動的に移行するようにプログラムされている。 For example, the period T1 is a period of a weak stimulation mode in which a relatively weak electrical stimulus is given, and a period T2 is a period of a strong stimulation mode in which a relatively strong electrical stimulus is given. Then, the low frequency treatment device 20 is programmed to automatically shift to the strong stimulation mode (period T2) after the end of the weak stimulation mode (period T1).
　この場合に、低周波治療器２０は、期間Ｔ１から期間Ｔ２に切り替わる時点で通知用パルス電流８５を供給させる。このように、低周波治療器２０は、治療用の電気的刺激を与える複数種類の低周波パルス電流８１，８２を切り替えてユーザに供給し、供給する低周波パルス電流の切り替わりに基づいて通知用パルス電流８５を供給する。 In this case, the low frequency treatment device 20 supplies the notification pulse current 85 at the time when the period T1 is switched to the period T2. In this way, the low-frequency treatment device 20 switches and supplies a plurality of types of low- frequency pulse currents 81 and 82 that give electrical stimulation for treatment to the user, and for notification based on the switching of the supplied low-frequency pulse currents. A pulse current of 85 is supplied.
　これにより、ユーザは、通知用パルス電流８５の知覚により、供給される低周波パルス電流が変化することを、視覚や聴覚によらずに認識することができる。したがって、ユーザは、視覚や聴覚に依存しない状態を維持しながら、治療の進行状態も把握することができる。 As a result, the user can recognize that the supplied low-frequency pulse current changes due to the perception of the notification pulse current 85, regardless of visual or auditory sense. Therefore, the user can grasp the progress state of the treatment while maintaining the state independent of sight and hearing.
　低周波治療器２０が弱刺激モード（期間Ｔ１）の終了後に強刺激モード(期間Ｔ２)に自動的に移行する際に通知用パルス電流８５を供給する場合について説明したが、低周波治療器２０は、弱刺激モードにおいて、ユーザが低周波治療器２０に対して強刺激モードへの移行を指示する操作を行った際に通知用パルス電流８５を供給してもよい。 The case where the low-frequency treatment device 20 supplies the notification pulse current 85 when the low-frequency treatment device 20 automatically shifts to the strong stimulation mode (period T2) after the end of the weak stimulation mode (period T1) has been described. May supply the notification pulse current 85 when the user performs an operation instructing the low frequency treatment device 20 to shift to the strong stimulation mode in the weak stimulation mode.
　低周波パルス電流８２が低周波パルス電流８１よりも振幅が大きい波形のパルス電流である場合について説明したが、低周波パルス電流８２は、低周波パルス電流８１の波形と異なる各種の波形のパルス電流とすることができる。 Although the case where the low frequency pulse current 82 is a pulse current having a waveform having a larger amplitude than the low frequency pulse current 81 has been described, the low frequency pulse current 82 is a pulse current having various waveforms different from the waveform of the low frequency pulse current 81. Can be.
＜低周波パルス電流及び通知用パルス電流の各供給予定タイミングが重なった場合の制御の具体例＞
　図１０は、低周波パルス電流及び通知用パルス電流の各供給予定タイミングが重なった場合の制御の具体例１を示す図である。 <Specific example of control when the scheduled supply timings of the low-frequency pulse current and the notification pulse current overlap>
FIG. 10 is a diagram showing a specific example 1 of control when the scheduled supply timings of the low frequency pulse current and the notification pulse current overlap.
　図１０において、低周波パルス電流タイミング１０１は、低周波パルス電流８１の供給予定タイミングを示している。低周波パルス電流８１の供給予定タイミングとは、治療用の電気的刺激を与えるために予め定められた、低周波パルス電流８１を供給すべきタイミングである。 In FIG. 10, the low-frequency pulse current timing 101 indicates the scheduled supply timing of the low-frequency pulse current 81. The scheduled supply timing of the low-frequency pulse current 81 is a predetermined timing at which the low-frequency pulse current 81 should be supplied in order to give an electrical stimulus for treatment.
　通知用パルス電流タイミング１０２は、通知用パルス電流８５の供給予定タイミングを示している。通知用パルス電流８５の供給予定タイミングとは、ユーザに治療の進行状態を通知するために予め定められた、通知用パルス電流８５を供給すべきタイミング（一例としては低周波パルス電流８１の供給開始から一定時間の経過後）である。 The notification pulse current timing 102 indicates the scheduled supply timing of the notification pulse current 85. The scheduled supply timing of the notification pulse current 85 is the timing at which the notification pulse current 85 should be supplied, which is predetermined to notify the user of the progress of the treatment (as an example, the supply start of the low frequency pulse current 81). After a certain period of time has passed).
　低周波パルス電流タイミング１０１及び通知用パルス電流タイミング１０２に示すように、図１０の例では、時点ｔ１において、低周波パルス電流８１の供給予定タイミングと通知用パルス電流８５の供給予定タイミングとが重なっている。 As shown in the low frequency pulse current timing 101 and the notification pulse current timing 102, in the example of FIG. 10, the scheduled supply timing of the low frequency pulse current 81 and the scheduled supply timing of the notification pulse current 85 overlap at the time point t1. ing.
　パルス電流波形１０３は、低周波パルス電流タイミング１０１及び通知用パルス電流タイミング１０２に基づいて低周波治療器２０が供給するパルス電流を示している。パルス電流波形１０３に示すように、低周波治療器２０は、時点ｔ１において通知用パルス電流８５を供給するとともに、低周波パルス電流８１の供給のタイミングを、低周波パルス電流タイミング１０１が示す供給予定タイミングから遅延させる。 The pulse current waveform 103 shows the pulse current supplied by the low frequency treatment device 20 based on the low frequency pulse current timing 101 and the notification pulse current timing 102. As shown in the pulse current waveform 103, the low-frequency treatment device 20 supplies the notification pulse current 85 at the time point t1, and the low-frequency pulse current timing 101 indicates the timing of supply of the low-frequency pulse current 81. Delay from the timing.
　すなわち、低周波治療器２０は、通知用パルス電流８５の供給を低周波パルス電流８１の供給に割り込ませる。なお、この場合、低周波パルス電流８１の供給の終了時点は、低周波パルス電流８１の供給のタイミングを遅延させた分だけ遅れることになる。 That is, the low frequency treatment device 20 interrupts the supply of the notification pulse current 85 with the supply of the low frequency pulse current 81. In this case, the end point of supply of the low frequency pulse current 81 is delayed by the amount of delay in the timing of supply of the low frequency pulse current 81.
　このように、低周波治療器２０は、低周波パルス電流８１の供給予定タイミングと通知用パルス電流８５の供給予定タイミングとが重なった場合に、通知用パルス電流８５の供給後に低周波パルス電流８１を供給する。これにより、低周波パルス電流８１の供給タイミングと通知用パルス電流８５の供給タイミングとが重ならないようにし、通知用パルス電流８５をユーザに確実に知覚させることができる。 As described above, in the low frequency treatment device 20, when the scheduled supply timing of the low frequency pulse current 81 and the scheduled supply timing of the notification pulse current 85 overlap, the low frequency pulse current 81 is supplied after the notification pulse current 85 is supplied. Supply. As a result, the supply timing of the low-frequency pulse current 81 and the supply timing of the notification pulse current 85 do not overlap, and the notification pulse current 85 can be reliably perceived by the user.
　図１１は、低周波パルス電流及び通知用パルス電流の各供給予定タイミングが重なった場合の制御の具体例２を示す図である。 FIG. 11 is a diagram showing a specific example 2 of control when the scheduled supply timings of the low frequency pulse current and the notification pulse current overlap.
　図１０に示した低周波パルス電流タイミング１０１及び通知用パルス電流タイミング１０２の例において、低周波治療器２０は、低周波パルス電流８１の供給のタイミングを遅延させるのではなく、時点ｔ１における低周波パルス電流８１の振幅を縮小してもよい。低周波パルス電流８１の振幅を縮小するとは、低周波パルス電流８１の供給予定タイミングと通知用パルス電流８５の供給予定タイミングとが重なっていなかった場合に供給が予定されていた低周波パルス電流８１の振幅よりも小さい振幅にすることである。 In the example of the low frequency pulse current timing 101 and the notification pulse current timing 102 shown in FIG. 10, the low frequency treatment device 20 does not delay the timing of supply of the low frequency pulse current 81, but the low frequency at the time point t1. The amplitude of the pulse current 81 may be reduced. Reducing the amplitude of the low-frequency pulse current 81 means that the low-frequency pulse current 81, which was scheduled to be supplied when the scheduled supply timing of the low-frequency pulse current 81 and the scheduled supply timing of the notification pulse current 85 do not overlap. The amplitude should be smaller than the amplitude of.
　このように、低周波治療器２０は、低周波パルス電流８１の供給予定タイミングと通知用パルス電流８５の供給予定タイミングとが重なった場合に、その低周波パルス電流８１の振幅を縮小する。これにより、低周波パルス電流８１と供給タイミングが重なった通知用パルス電流８５が、低周波パルス電流８１によって知覚できなくなることを抑制することができる。このため、低周波パルス電流８１の供給の進行（例えば終了時刻）への影響を抑制しつつ、通知用パルス電流８５をユーザに知覚させることができる。 In this way, the low-frequency treatment device 20 reduces the amplitude of the low-frequency pulse current 81 when the scheduled supply timing of the low-frequency pulse current 81 and the scheduled supply timing of the notification pulse current 85 overlap. As a result, it is possible to prevent the notification pulse current 85, which overlaps the supply timing with the low frequency pulse current 81, from becoming imperceptible due to the low frequency pulse current 81. Therefore, the user can perceive the notification pulse current 85 while suppressing the influence on the progress (for example, end time) of the supply of the low frequency pulse current 81.
　又は、低周波治療器２０は、同様の低周波パルス電流タイミング１０１及び通知用パルス電流タイミング１０２の例において、時点ｔ１における低周波パルス電流８１の供給をキャンセルしてもよい。 Alternatively, the low frequency treatment device 20 may cancel the supply of the low frequency pulse current 81 at the time point t1 in the same example of the low frequency pulse current timing 101 and the notification pulse current timing 102.
　このように、低周波治療器２０は、低周波パルス電流８１の供給予定タイミングと通知用パルス電流８５の供給予定タイミングとが重なった場合に、その低周波パルス電流８１を供給しないようにしてもよい。これにより、低周波パルス電流８１の供給タイミングと通知用パルス電流８５の供給タイミングとが重ならないようにし、通知用パルス電流８５をユーザに確実に知覚させることができる。このため、低周波パルス電流８１の供給の進行（例えば終了時刻）への影響を抑制しつつ、通知用パルス電流８５をユーザに確実に知覚させることができる。 As described above, the low-frequency treatment device 20 does not supply the low-frequency pulse current 81 when the scheduled supply timing of the low-frequency pulse current 81 and the scheduled supply timing of the notification pulse current 85 overlap. good. As a result, the supply timing of the low-frequency pulse current 81 and the supply timing of the notification pulse current 85 do not overlap, and the notification pulse current 85 can be reliably perceived by the user. Therefore, the user can surely perceive the notification pulse current 85 while suppressing the influence on the progress (for example, end time) of the supply of the low frequency pulse current 81.
　図１２は、低周波パルス電流及び通知用パルス電流の各供給予定タイミングが重なった場合の制御の具体例３を示す図である。 FIG. 12 is a diagram showing a specific example 3 of control when the scheduled supply timings of the low frequency pulse current and the notification pulse current overlap.
　図１０に示した低周波パルス電流タイミング１０１及び通知用パルス電流タイミング１０２の例において、低周波治療器２０は、低周波パルス電流８１の供給のタイミングを遅延させるのではなく、低周波パルス電流８２の供給のタイミングを遅延させてもよい。 In the example of the low frequency pulse current timing 101 and the notification pulse current timing 102 shown in FIG. 10, the low frequency treatment device 20 does not delay the timing of supply of the low frequency pulse current 81, but the low frequency pulse current 82. The timing of supply may be delayed.
　このように、低周波治療器２０は、低周波パルス電流８１の供給予定タイミングと通知用パルス電流８５の供給予定タイミングとが重なった場合に、通知用パルス電流８５の供給後に低周波パルス電流８１を供給してもよい。これにより、低周波パルス電流８１の供給タイミングと通知用パルス電流８５の供給タイミングとが重ならないようにし、通知用パルス電流８５をユーザに確実に知覚させることができる。このため、低周波パルス電流８１の供給への影響を抑制しつつ、通知用パルス電流８５をユーザに確実に知覚させることができる。 As described above, in the low frequency treatment device 20, when the scheduled supply timing of the low frequency pulse current 81 and the scheduled supply timing of the notification pulse current 85 overlap, the low frequency pulse current 81 is supplied after the notification pulse current 85 is supplied. May be supplied. As a result, the supply timing of the low-frequency pulse current 81 and the supply timing of the notification pulse current 85 do not overlap, and the notification pulse current 85 can be reliably perceived by the user. Therefore, the user can surely perceive the notification pulse current 85 while suppressing the influence on the supply of the low frequency pulse current 81.
＜各パルス電流の生成方法の変形例＞
　本体部３が、低周波パルス電流を生成するためのパルス電圧と、通知用パルス電流を生成するためのパルス電圧と、をパッド２１に印加する構成について説明したが、このような構成に限らない。例えば、本体部３は、低周波パルス電流の波形と、通知用パルス電流の波形と、を合成した波形に基づくパルス電圧をパッド２１に印加してもよい。 <Modification example of each pulse current generation method>
The configuration in which the main body 3 applies a pulse voltage for generating a low-frequency pulse current and a pulse voltage for generating a notification pulse current to the pad 21 has been described, but the configuration is not limited to such a configuration. .. For example, the main body 3 may apply a pulse voltage to the pad 21 based on a waveform obtained by combining a waveform of a low frequency pulse current and a waveform of a notification pulse current.
＜通知用パルスの変形例＞
　通知用パルス電流の具体例として、低周波パルス電流のパルス幅よりも短いパルス幅、低周波パルス電流の周期よりも短い周期、及び、低周波パルス電流よりも小さい振幅を有し２回繰り返すパルス電流について説明したが、通知用パルス電流はこれに限らず、低周波パルス電流として区別して知覚可能な、各種のパルス電流としてもよい。 <Modification example of notification pulse>
Specific examples of the notification pulse current are a pulse width shorter than the pulse width of the low frequency pulse current, a cycle shorter than the cycle of the low frequency pulse current, and a pulse having an amplitude smaller than that of the low frequency pulse current and repeating twice. Although the current has been described, the notification pulse current is not limited to this, and may be various pulse currents that can be distinguished and perceived as low frequency pulse currents.
　例えば、通知用パルス電流は、繰り返さずに１回のみ供給されるパルス電流であってもよいし、３回以上繰り返すパルス電流であってもよい。また、通知用パルス電流は、振幅、パルス幅、及び周期の少なくともいずれかが変化しながら繰り返すパルス電流であってもよい。例えば、通知用パルス電流は、ユーザに対して印象が残るような、特定のリズムを有するパルス電流であってもよい。 For example, the notification pulse current may be a pulse current that is supplied only once without repeating, or may be a pulse current that repeats three or more times. Further, the notification pulse current may be a pulse current that repeats while changing at least one of the amplitude, the pulse width, and the period. For example, the notification pulse current may be a pulse current having a specific rhythm that leaves an impression on the user.
＜治療の進行に関する通知のための刺激の他の例＞
　治療の進行に関する通知のための、治療用の電気的刺激とは異なる皮膚もしくは筋肉への刺激として、通知用パルス電流の供給について説明したが、通知のための刺激は通知用パルス電流に限らない。例えば、振動を発生させるバイブレータ等を低周波治療器１０に設け、振動による皮膚もしくは筋肉への刺激により、治療の進行に関する通知を行うようにしてもよい。また、ユーザの皮膚もしくは筋肉を加熱又は冷却する装置を低周波治療器１０に設け、加熱又は冷却による皮膚もしくは筋肉への刺激により、治療の進行に関する通知を行うようにしてもよい。また、ユーザの皮膚もしくは筋肉を加圧又は減圧する装置を低周波治療器１０に設け、加圧又は減圧による皮膚もしくは筋肉への刺激により、治療の進行に関する通知を行うようにしてもよい。 <Other examples of stimuli for notification of treatment progress>
The supply of notification pulse currents has been described as a skin or muscle stimulus that is different from the therapeutic electrical stimulus for notification of the progress of treatment, but the notification stimulus is not limited to the notification pulse current. .. For example, a vibrator or the like that generates vibration may be provided in the low frequency treatment device 10 to notify the progress of the treatment by stimulating the skin or muscle by the vibration. Further, a device for heating or cooling the user's skin or muscle may be provided in the low frequency treatment device 10, and the skin or muscle may be stimulated by heating or cooling to notify the progress of the treatment. Further, a device for pressurizing or depressurizing the user's skin or muscle may be provided in the low frequency treatment device 10 so as to notify the progress of the treatment by stimulating the skin or muscle by the pressurization or depressurization.
＜低周波治療器１０の他の例である低周波治療器２００の構成＞
　図１３は、低周波治療器１０の他の一例である低周波治療器２００の構成を示す図である。 <Structure of the low frequency treatment device 200, which is another example of the low frequency treatment device 10>
FIG. 13 is a diagram showing the configuration of the low frequency treatment device 200, which is another example of the low frequency treatment device 10.
　低周波治療器１０の一例としてコードレスタイプの低周波治療器２０について説明したが、低周波治療器１０は、例えば図１３に示すような、有線タイプの低周波治療器２００であってもよい。 Although the cordless type low frequency treatment device 20 has been described as an example of the low frequency treatment device 10, the low frequency treatment device 10 may be a wired type low frequency treatment device 200 as shown in FIG. 13, for example.
　低周波治療器２００は、治療器の本体部２０５と、治療部位に貼り付けるための一対のパッド２７０と、本体部２０５とパッド２７０とを電気的に接続するためのコード２８０と、を含む。低周波治療器２００も、低周波治療器２０と同様に、低周波パルス電流を供給することで、ユーザの肩凝りをほぐす等の治療を行う低周波治療器である。 The low frequency treatment device 200 includes a main body 205 of the treatment device, a pair of pads 270 to be attached to the treatment site, and a cord 280 for electrically connecting the main body 205 and the pad 270. Similar to the low frequency treatment device 20, the low frequency treatment device 200 is also a low frequency treatment device that performs treatment such as relieving stiff shoulders of a user by supplying a low frequency pulse current.
　パッド２７０は、シート状の形状を有し、ユーザの身体に取り付けられる。パッド２７０の一方の面（身体と接触しない面）には、他方の面（身体と接触する面）に形成されている電極（図示しない）に対応したプラグが設けられている。電極は、例えば、導電性のゲル状材料等により形成される。 The pad 270 has a sheet-like shape and is attached to the user's body. One surface of the pad 270 (a surface that does not come into contact with the body) is provided with a plug corresponding to an electrode (not shown) formed on the other surface (a surface that comes into contact with the body). The electrode is formed of, for example, a conductive gel-like material.
　コード２８０のプラグ２８２とパッド２７０側のプラグとを接続し、コード２８０を本体部２０５のジャックに差し込むことにより、本体部２０５とパッド２７０とが接続される。なお、一方のパッド２７０に形成されている電極の極性がプラスの場合、他方のパッド２７０に形成されている電極の極性はマイナスとなる。 By connecting the plug 282 of the cord 280 and the plug on the pad 270 side and inserting the cord 280 into the jack of the main body 205, the main body 205 and the pad 270 are connected. When the polarity of the electrode formed on one pad 270 is positive, the polarity of the electrode formed on the other pad 270 is negative.
　本体部２０５には、各種ボタンで構成される操作インタフェース２３０と、ディスプレイ２６０とが設けられている。操作インタフェース２３０は、電源のオン／オフを切り替えるための電源ボタン２３２と、治療モードの選択を行うためのモード選択ボタン２３４と、治療開始ボタン２３６と、電気刺激の強さ（刺激強度）の調整を行うための調整ボタン２３８とを含む。 The main body 205 is provided with an operation interface 230 composed of various buttons and a display 260. The operation interface 230 includes a power button 232 for switching the power on / off, a mode selection button 234 for selecting a treatment mode, a treatment start button 236, and adjustment of the strength (stimulation intensity) of electrical stimulation. Includes an adjustment button 238 for performing.
　なお、操作インタフェース２３０は、上記構成に限られず、後述するユーザによる各種操作を実現できる構成であればよい。操作インタフェース２３０は、例えば、その他のボタン、ダイヤルやスイッチ等により構成されていてもよい。 The operation interface 230 is not limited to the above configuration, and may be any configuration that can realize various operations by the user described later. The operation interface 230 may be composed of, for example, other buttons, dials, switches, or the like.
　ディスプレイ２６０には、電気刺激強度、治療の残り時間、治療モード、パッド２７０の装着状態等が表示されたり、各種メッセージが表示されたりする。 The display 260 displays the electrical stimulation intensity, the remaining treatment time, the treatment mode, the wearing state of the pad 270, etc., and various messages are displayed.
　低周波治療器２００においては、本体部２０５及びパッド２７０が、低周波治療器２０における本体部３及びパッド２１に対応する機能を有する。すなわち、本体部２０５は、パッド２７０から、治療用の電気的刺激を与える低周波パルス電流と、治療の進行に関する通知を行う電気的刺激を与える通知用パルス電流と、を供給させる制御を行う。 In the low frequency treatment device 200, the main body portion 205 and the pad 270 have a function corresponding to the main body portion 3 and the pad 21 in the low frequency treatment device 20. That is, the main body 205 controls the pad 270 to supply a low-frequency pulse current that gives an electrical stimulus for treatment and a notification pulse current that gives a notification about the progress of the treatment.
＜制御プログラム＞
　低周波治療器１０、低周波治療器２０、及び低周波治療器２００の制御プログラムは、プログラムをコンピュータが読取可能な一時的でない（ｎｏｎ－ｔｒａｎｓｉｔｏｒｙ）記憶媒体に記憶される。このような「コンピュータ読取可能な記憶媒体」は、例えば、ＣＤ－ＲＯＭ（Ｃｏｍｐａｃｔ　Ｄｉｓｃ－ＲＯＭ）等の光学媒体や、ＵＳＢ（Ｕｎｉｖｅｒｓａｌ　Ｓｅｒｉａｌ　Ｂｕｓ）メモリ又はメモリカード等の磁気記憶媒体等を含む。また、このようなプログラムを、インターネット等のネットワークを介したダウンロードによって提供することもできる。 <Control program>
