Description

The present invention relates to a deep muscle stimulator.

2. Description of the Related Art Conventionally, there are electrotherapy devices that electrically stimulate muscles inside the body. For example, a low-frequency treatment device, which is a general electric treatment device, electrically stimulates muscles inside the body by guiding low-frequency pulses to conductors attached to two positions on the surface of the body.
In the case of an electrotherapy device using a low frequency, the skin resistance increases, so that the subject can feel a tingling electrical stimulation on the surface muscle about 3 to 5 mm below the skin. However, muscle stiffness is usually felt in the deep muscle (inner muscle), which is a muscle deeper than the surface muscle. That is, no matter how much electrical stimulation is given to the superficial muscles to cause contraction and relaxation, unless deep blood muscles with poor blood flow are electrically stimulated to cause contraction and relaxation, The loosening of muscle stiffness felt by the practitioner is temporary. For example, as early as the day the procedure is performed, the muscles may become tense and the pain may be reappeared. Further, the deep muscle, which has poor blood flow and is in a tense state, may sometimes leave the skeleton of the subject in a distorted state.

In this case, a method of increasing the voltage of the electric power output from the electric therapy device in order to give a stimulus to the deep muscles can be considered. However, when the voltage is increased, the stimulation of the superficial muscles becomes stronger accordingly, so that the subject cannot bear the pain of the stimulation of the superficial muscles. That is, it has been difficult for the conventional electrotherapy device using a low frequency to give sufficient stimulation to the deep muscle while suppressing stimulation on the superficial muscle.
As described above, it is well known by those skilled in the art that it is more effective to perform electrical stimulation on deep muscles rather than on superficial muscles in an operation using an electrotherapy device. For example, Patent Document 1 proposes an electrotherapy device that outputs a medium-frequency pulse for the purpose of electrically stimulating deep muscles in the body. In this case, the skin resistance in the subject is smaller than that in the case of low frequency, so that electrical stimulation can be given to the deep muscle about 3 to 4 cm below the skin.

JP, 2005-53943, A

However, the conventional medium-frequency or high-frequency electrotherapy devices including Patent Document 1 can provide electrical stimulation to the deep muscles, but the stimulation provided to the muscle is smaller than that in the case of low frequency. Will end up.
That is, in the case of a low-frequency electrotherapy device, since the skin resistance is large and the stimulation given to the muscle is large, the muscle relaxing effect of the superficial muscle and the blood flow improving effect can be expected, but it is sufficient for the deep muscle. Can't be stimulated.
On the other hand, in the case of a mid-frequency or high-frequency electrotherapy device, although deep muscles can be given a certain amount of stimulation, the skin resistance is smaller than in the case of low frequencies, so sufficient stimulation is given to the muscles. Can't give.
For this reason, the conventional medium-frequency or high-frequency electrotherapy device cannot be expected to have the effect of the maximum contraction and relaxation of the deep muscle and the blood flow improving effect.

The present invention has been made in view of such a situation, the deep muscles of the subject, the effect of maximum contraction and muscle relaxation of the deep muscles by giving sufficient stimulation by electrical energy, blood The purpose is to improve the flow.

Embodiments of the present invention will be described below with reference to the drawings.
(Deep muscle stimulator)
FIG. 1 is a functional block diagram showing the configuration of a deep muscle stimulation device 1 according to an embodiment of the present invention.

As shown in FIG. 1, the deep muscle stimulating device 1 includes a power supply unit 10, a main body unit 11, and a conductor unit 12.
The power supply unit 10 steps down the voltage of the AC power input from the AC power supply AC, converts it into DC power, and outputs the DC power. In this embodiment, a double insulated AC adapter is used.

The main body 11 includes an operation unit 101, a control unit 102, and a sine wave output unit 103.
The operation unit 101 includes various switches for the practitioner to operate the deep muscle stimulation device 1. The operation unit 101 also includes a display screen that outputs character information, image information, and the like for assisting the operator's operation. It should be noted that a display element including an LED (Light Emitting Diode) or the like can be used for the display screen. The practitioner can use the deep muscle stimulator 1 by operating various switches while looking at this display screen.
The control unit 102 controls the entire deep muscle stimulator 1 and controls the sine wave output unit 103 to output a sine wave based on the content of the operation performed on the operation unit 101 by the practitioner.
The sine wave output unit 103 outputs electric power of a sine wave having a predetermined frequency. The sine wave of the predetermined frequency output by the sine wave output unit 103 is flowed to the deep muscle of the body of the subject through the conductor 12.

Here, the frequency of the sine wave output by the sine wave output unit 103 is a low frequency of about 40 Hz to 120 Hz. Further, even with the same low frequency, unlike the low frequency pulse wave used in a general low frequency treatment device, the sine wave output by the sine wave output unit 103 has a distortion rate of 30% or less. It is a low frequency sine wave.
Since such a sine wave has a property that current stimulation is difficult to spread near the surface muscle, even if the voltage is increased, the stimulation to the surface muscle of the subject is small. Therefore, it is possible to raise the voltage of the sine wave output from the sine wave output unit 103 to a level at which the deep muscles can be contracted and relaxed to the maximum extent beyond the fat layer in the body of the subject. Becomes
For example, it is possible to give sufficient stimulation to large muscles such as the buttocks and abdomen of the subject and the muscles of the back. The specific functional configuration of the sine wave output unit 103 will be described later with reference to FIG.

The conductor portion 12 is composed of a pair of conductors composed of sinusoidal conductors 201a and 201b. The sine wave conductors 201a and 201b flow the sine wave output from the sine wave output unit 103 into the body of the subject while being attached to the skin of the subject in a state of being in contact with or detachable from the subject.

Next, a specific configuration of the sine wave output unit 103 described above will be described.
FIG. 2 is a circuit diagram showing a specific configuration of the sine wave output unit 103 of FIG.

As shown in FIG. 2, the sine wave output unit 103 includes an H-bridge output circuit H, a waveform shaping circuit W, an output transformer circuit T, and an impedance circuit Z.
The H-bridge output circuit H switches the polarities of the current and voltage in the power supplied from the AC power supply AC to the waveform shaping circuit W based on a PWM (Pulse Width Modulation) signal.
The waveform shaping circuit W shapes the waveform of the power output from the H-bridge output circuit H to convert it into a sine wave having a predetermined frequency and outputs the sine wave.
The output transformer circuit T boosts the voltage of the electric power converted into a sine wave having a predetermined frequency by the waveform shaping circuit W.

As described above, the sine wave output by the waveform shaping circuit W is a low frequency sine wave having a frequency of about 40 Hz to 120 Hz and a distortion rate of 30% or less. Therefore, the output transformer circuit T applies the sinusoidal voltage to the maximum contraction and relaxation of the deep muscle beyond the fat layer in the body of the subject without giving strong stimulation to the surface muscle of the subject. It can be boosted to a level where it can be done.
The impedance circuit Z controls the voltage so that voltage fluctuation does not occur when the sine wave conductors 201a and 201b that are in contact with the body surface of the subject are separated from the surface of the body of the subject. A snubber circuit may be connected as the impedance circuit Z.
The low frequency sine wave output from the sine wave output unit 103 having the above-described configuration is flown into the body of the subject via the sine wave conductors 201a and 201b, so that the deep muscles of the subject are exposed. It is possible to give sufficient stimulation to cause maximum contraction and relaxation.

FIG. 3 is a functional block diagram showing the configuration of the deep muscle stimulating device 2 according to another embodiment of the present invention (that is, an embodiment further including a function of outputting a DNS modulated wave).

The deep muscle stimulating device 1 described with reference to FIG. 1 is configured to flow only a sine wave into the body of the subject. However, it is also possible to flow a predetermined modulation wave together with the sine wave into the body of the subject. For example, the deep muscle stimulating device 2 shown in FIG. 3 can cause a modulated wave of the patent No. 5423957 owned by the present applicant (hereinafter referred to as “DNS modulated wave”) to flow into the body of the subject together with the sine wave. it can.

Here, the DNS modulated wave is a third frequency higher than the first frequency due to a pulse signal whose repetition frequency changes continuously or stepwise between the first frequency and the second frequency lower than the first frequency. A modulated wave that is a modulated carrier wave. Specifically, the DNS modulated wave is from a first frequency in an ultra long frequency band (ULF: Ultra Low Frequency, 300 Hz to 3 KHz) to a second frequency in an ultra long frequency band (SLF: Super Low Frequency, 30 Hz to 300 Hz). Changes continuously or stepwise, the change from the second frequency to the first frequency jumps, and the cycle of changing the repeating frequency increases with time.
For example, the waveform of the carrier wave of the third frequency whose frequency is 4,000 Hz may be amplitude-modulated to obtain a DNS modulated wave of 50 to 1,000 Hz. As a result, it is possible to stimulate a wide range of muscles via the nerves of the subject while reducing the tingling sensation of stimulation of the subject's surface muscles.

As shown in FIG. 3, the deep muscle stimulating device 2 further includes a DNS modulated wave output unit 104 and DNS modulated wave conductors 202a and 202b in addition to the configuration of the deep muscle stimulating device 1 of FIG.
That is, the conductor portion 12 of the deep muscle stimulator 2 is composed of two pairs of conductors, which are sinusoidal wave conductors 201a and 201b and DNS modulated wave conductors 202a and 202b.

The DNS modulated wave output unit 104 outputs a DNS modulated wave. Specifically, the control unit 102 outputs the DNS modulated wave by executing control to cause the DNS modulated wave output unit 104 to output the DNS modulated wave.
The DNS modulated wave conductors 202a and 202b are attached to the skin of the subject in a state of being in contact with or being removable. The DNS modulated wave conductors 202a and 202b flow the DNS modulated wave output from the DNS modulated wave output unit 104 into the body of the subject.
That is, the DNS modulated wave output by the DNS modulated wave output unit 104 is flown into the nerve of the body of the subject via the DNS modulated wave conductors 202a and 202b. Note that, as described above, the specific functional configuration of the DNS modulated wave output unit 104 is as disclosed in the patent publication (Patent No. 5423957) relating to the patent right owned by the present applicant.

With the deep muscle stimulating device 2 having such a configuration, the sine wave and the DNS modulated wave can be simultaneously flowed into the body of the subject. This makes it possible to simultaneously perform the approach to the deep muscles of the subject by the sine wave and the approach to the nerve of the subject by the DNS modulated wave. Therefore, the effect of maximum contraction and muscle relaxation of deep muscles and the effect of improving blood flow can be further enhanced, and the operation time can also be shortened.

(Flexible conductor)
Next, with reference to FIG. 4, a method of efficiently flowing the above-described low-frequency sine wave into the body of the subject will be described.

FIG. 4 is an image diagram showing an example of the external configuration of a conductor 301a for flowing electrical energy into the body of the subject R, which is conventionally present.

2. Description of the Related Art Conventionally, a metallic conductor is used as a conductor that is a portion to be brought into contact with the surface of the body of the subject. For example, in the conductor 301a shown in FIG. 4, a towel 312 containing water is wound around a metal electrode 311. This is because the electric resistance of the skin of the subject is reduced and the current density is averaged to facilitate the flow of an electric current between the metal part to be the electrode and the skin of the subject. In addition, usually, the fibers are impregnated with saline or tap water (for example, towel 312 as shown in FIG. 4, gauze, cotton, etc.) is coated on the metal electrode to perform the operation.

However, since the electrode 311 of the conductor 301a is made of metal and hard, even if it is covered with the towel 312 or the like, the subject may feel pain. Further, since the surface of the human body is formed of a curved line, whereas the surface of the electrode 311 is formed of a flat surface, the conductor cannot be smoothly brought into close contact with the surface of the body of the subject. For this reason, there is a problem that the electrical energy conduction efficiency is deteriorated.
Therefore, it has been possible to solve the above-mentioned problems by giving flexibility to the electrodes forming the conductors that come into contact with the surface of the body of the subject.
A conductor provided with such a flexible electrode will be described with reference to FIG.

FIG. 5 is an image diagram showing an example of the external configuration of the flexible conductors 401a and 401b that causes the sine wave output from the sine wave output unit 103 to flow into the body of the subject R.

As shown in FIG. 5, the flexible conductors 401 a and 401 b are composed of a flexible electrode 411 and a water absorbing member 412.
The practitioner S holds the flexible conductors 401a and 401b in their respective hands and brings them into contact with the skin of the practitioner R to generate a sine wave output from the sine wave output unit 103. To the subject's body.
The flexible electrode 411 forming the flexible conductors 401a and 401b is entirely made of a conductive and flexible material. Here, the flexible electrode 411 is not particularly limited as long as it is a conductive and flexible material, but in this embodiment, conductive rubber is used. With such a configuration of the electrodes, the subject R can easily receive the treatment without feeling pain.
Moreover, since the flexible electrode 411 can be freely deformed and can be brought into close contact with the body of the subject smoothly according to the curve, the sine wave can be efficiently flowed into the body. Further, for the practitioner S, there is an effect that the treatment is easy.

Furthermore, since the flexible electrode 411 is wholly covered with the water absorbent member 412, by performing a treatment with the water absorbent member 412 containing a predetermined amount of water, the flexible electrode 411 is efficiently applied to the muscles inside the body of the subject R. Sine wave can be flowed well. The water absorbent member 412 may be a fiber material such as a conventionally used towel (for example, the towel 312 in FIG. 4), but it may cover the entire flexible electrode 411 and continue to contain water for a long time. It is also possible to employ a soft porous material that can be used (for example, sponge). When a sponge is used as the water-absorbing member 412, compared with a towel that has been conventionally used, the part that comes into contact with human skin has a softer feel, so that the subject R can more comfortably receive the treatment. it can.

(Deep muscle stimulator that attaches a conductor to each body of the practitioner and the practitioner)
Returning to FIG. 1, the sinusoidal wave conductors 201a and 201b connected to the sinusoidal wave output unit 103 are usually composed of a pair, and both are brought into contact with or affixed to the surface of the body of the subject R to generate a sinusoidal wave. The deep muscles are stimulated by flushing.
However, by attaching one of the pair of sinusoidal wave conductors to the foot or arm of the practitioner S and attaching the other one to a part of the body of the practitioner R, the bare hand of the practitioner S can be used. As a result, a sine wave can be made to flow inside the body of the subject R. Such a method will be described with reference to FIG.

FIG. 6 is an image diagram showing an example of the external configuration of the deep muscle stimulating device 2 when the conductor is attached to the body of each of the operator S and the person R to be operated.

As shown in FIG. 6, of the pair of sine wave conductors 501a and 501b, the sine wave conductor 501a is attached to the surface of the body of the subject R and the sine wave conductor 501b is attached to the surface of the body of the subject S. Then, the operator S massages the person R to be treated with the bare hand SH. As a result, a sine wave is caused to flow into the body of the subject R via the bare hand SH of the subject S. In the example shown in FIG. 6, the sine wave conductor 501a is attached to a part of the body of the subject R, and the sine wave conductor 501b is attached to the ankle of the subject S using the belt B.
In this case, the sine wave conductor 501a attached to the subject R, the muscles of the subject R, the bare hand SH of the subject S, and the sine wave conductor 501b attached to the ankle of the subject S are: One energizing circuit will be formed. Therefore, the sine wave can be made to flow into the body of the subject R via the bare hand SH of the subject S. The belt B having the sine wave conductor 501b attached may be wound around the other part of the body such as the arm of the practitioner S instead of the ankle.

As described above, by applying the sine wave into the body of the subject R through the bare hand SH of the subject S, the muscles of the subject R such as the facial muscles of the subject R are relatively shallow and delicate. It enables delicate treatment of parts. For example, it is also possible to activate the lymphatic flow by the technique of the practitioner S, and enhance the effect of a treatment (lymph drainage) that collects and discharges foreign substances and waste products that are unnecessary for the body of the subject R.
Furthermore, it is more comfortable for the subject R to receive the sine wave through the fingertips of the bare hand SH of the practitioner S than when receiving the sine wave through the sine wave conductors 501a and 501b. Can be treated.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a range in which the object of the present invention can be achieved are included in the present invention. Is.

For example, the flexible electrode 411 shown in FIG. 5 is connected to the sine wave output unit 103, but is not limited to this. The flexible electrode 411 may be connected to the DNS modulated wave output 104 shown in FIG.

Further, the sinusoidal wave conductors 501a and 501b illustrated in FIG. 6 may include the flexible electrode 411 similarly to the flexible conductors 401a and 401b illustrated in FIG.
Furthermore, in the example of FIG. 6, a pair of sinusoidal wave conductors 501a and 501b connected to the sinusoidal wave output unit 103 is used, but the invention is not limited to this. A pair of DNS modulated wave conductors 202a and 202b connected to the DNS modulated wave output unit 104 shown in FIG. 3 may be used.
