Summary of the Invention

Problems to be Solved by the Invention

[0005] As a result of researching the low-frequency treatment device and conducting various experiments, the applicant has found that more favorable results can be obtained by applying an electrical stimulus to the body while changing the frequency of the current flowing through the electrodes.

[0006] An object of the present invention is to provide a low-frequency treatment device and a low-frequency treatment method capable of changing the frequency of the current flowing through the body via an electrode.

Means for Solving the Problems

[0007] The low-frequency treatment device and low-frequency treatment method of the present invention have the following configuration.

[0008] (1) Multiple electrode bodies (for example, electrode rods 20, 20) that come into contact with the user's body, The electrode body is provided with a current generator (for example, current generator 10) that passes a low-frequency current through it. The current generator is, A reference frequency setting unit (for example, reference frequency setting unit 120) for setting the target frequency, A frequency range division unit (for example, frequency range division unit 121) divides a frequency range of a predetermined width into multiple stages based on the target frequency set in the reference frequency setting unit, A frequency switching unit (for example, frequency switching unit 122) sets multiple distinct frequencies divided by the frequency range division unit, The device is characterized by having a current output unit (for example, a current output unit 123) that generates a current based on the frequency set by the frequency switching unit and supplies current to the electrode body.

[0009] According to the present invention configured in this way, a low-frequency treatment device is provided that performs a treatment on a user by applying a low-frequency current. By setting multiple stages of different frequencies divided in the frequency range division unit, the user is given electrical stimulation by a low-frequency current whose target frequency is fluctuated (for example, wobbled) within a predetermined frequency range. This makes it easier for the effects expected from the current at the target frequency to appear. Thus, according to the present invention, it is possible to provide a low-frequency treatment device that can change the frequency of the current flowing through the electrodes.

[0010] (2) The frequency switching unit sets the frequency by switching between multiple frequency levels in a loop at regular intervals in an order that gradually decreases from a high frequency, The current output unit is characterized by outputting a current of a decayed wave during the specified time period.

[0011] According to the present invention configured in this manner, by utilizing attenuated waves, it is possible to suppress the generation of frictional heat within cells, which is often seen when using square waves (pulse waves). In this way, by utilizing attenuated waves, it is possible to eliminate the frictional heat effect and concentrate on the frequency effect.

[0012] (3) The current output unit is characterized by outputting a current with a waveform offset in the positive direction.

[0013] According to the present invention configured in this way, by using a current with a waveform offset in the positive direction, the effects expected from a current at the target frequency become more readily apparent.

[0014] (4) The plurality of electrodes include a left-hand electrode body (e.g., a left-hand electrode rod 20L) that is held in the user's left hand, and a right-hand electrode body (e.g., a right-hand electrode rod 20R) that is held in the user's right hand, The left-hand electrode body and the right-hand electrode body are characterized by each having a gripping portion for the user to hold (for example, the central part of the electrode rod 20), a contact portion that can come into contact with a part of the user's body other than the palm (for example, one end of the electrode rod 20), and a connecting portion (for example, the other end of the electrode rod 20) that is connected to the current generator and supplies current to the gripping portion and the contact portion.

[0015] In this context, the palm of the hand is the part of the body that can sense the most delicate stimuli. With the present invention configured in this way, by gripping the left-hand electrode body with the left hand and the right-hand electrode body with the right hand, it becomes possible to transmit frequency signals to the body without being obstructed by subcutaneous fat. Furthermore, by gripping the left-hand electrode body and the right-hand electrode body with both hands and bringing the contact points of the left-hand electrode body and the contact points of the right-hand electrode body into contact with, for example, the lower left abdomen and the lower right abdomen, the frequency signals are transmitted not only to the upper body but also to the lower body, resulting in electrical stimulation throughout the entire body and making it easier for the expected effects of the target frequency current to appear.

[0016] (5) A low-frequency treatment method for performing treatment on a user using the low-frequency treatment device, comprising: While the user holds the gripping portion, with the contact portion being brought into contact with a portion different from the portion where the treatment on the user is to be performed, causing a current to flow through the electrode body by the current output portion.

[0017] According to the present invention configured as described above, when the user holds the gripping portion, it becomes possible to transmit a frequency signal to the body without being obstructed by subcutaneous fat, and by bringing the contact portion into contact with a portion different from the portion where the treatment on the user is to be performed, it becomes possible to cause a current to flow through the entire body rather than in a narrow range such as the treatment portion. As a result, the effects expected from the treatment are more likely to appear.

Effects of the Invention

[0018] According to the present invention, it is possible to provide a low-frequency treatment device capable of changing the frequency of the current flowing through the body via an electrode.

[0020] The present invention will be described in more detail below using preferred embodiments. However, the embodiments described below are merely examples of the present invention, and the present invention is not limited thereto.

[0021] The configuration of a low-frequency treatment device in one embodiment of the present invention will be described.

[0022] [Low-frequency treatment device 1] Figure 1 is an explanatory diagram showing an example of the configuration of a low-frequency treatment device 1 in one embodiment of the present invention.

[0023] As shown in Figure 1, the low-frequency treatment device 1 comprises a current generator 10, two electrode rods 20, 20, and a cable 30.

[0024] The current generator 10 supplies low-frequency current to two electrode rods 20, 20. The electrode rods 20 are long, conductive metal rods. The cable 30 comprises two long conductive cables 31, 31, a main unit connector 32, and electrode-side connectors 33, 33. The two conductive cables 31, 31 extend from the main unit connector 32, and electrode-side connectors 33, 33 are attached to the ends of the conductive cables 31, 31, respectively.

[0025] The main unit connector 32 is connected to the connector portion 16 of the current generator 10, and two conductive cables 31, 31 extend from one main unit connector 32, with electrode rods 20, 20 connected to the other ends of the conductive cables 31, 31. One conductive cable 31 is red, and the other conductive cable 31 is black, with the electrode rod 20 connected to the red cable being the positive pole and the electrode rod 20 connected to the black cable being the negative pole. In this embodiment, the electrode rod 20 held in the left hand may be referred to as the left-hand electrode rod 20L, and the electrode rod 20 held in the right hand may be referred to as the right-hand electrode rod 20R. Furthermore, the left-hand electrode rod 20L is connected to the red conductive cable 31, and the right-hand electrode rod 20R is connected to the black conductive cable 31.

[0026] [Current generator 10] The current generator 10 is composed of a power supply unit 11, a control unit 12, a storage unit 13, a display unit 14, an operation input unit 15, and a connector unit 16. The power supply unit 11 supplies electricity to each component of the current generator 10. The control unit 12 controls the entire current generator 10. The memory unit 13 stores various programs and data for controlling the current generator 10. The display unit 14 consists of a liquid crystal panel and displays various information such as the name of the treatment program and the function names of the buttons. The operation input unit 15 includes switches and the like that are operated by the user. The connector section 16 is equipped with a connector and the like for connecting to the main body-side connector 32 of the cable 30.

[0027] [Control Unit 12] Figure 2 is an explanatory diagram showing an example of the configuration of the control unit 12. The control unit 12 performs the functions of a reference frequency setting unit 120, a frequency range division unit 121, a frequency switching unit 122, and a current output unit 123 by executing a program stored in the memory unit 13.

[0028] The reference frequency setting unit 120 sets the target frequency. The target frequency is set by the user operating the operation input unit 15. The target frequency is the frequency that is optimal for producing a specific effect. Specifically, for beauty, anti-aging, immune enhancement, metabolism promotion, healing, and pathogen lethality, resonant frequencies and lethal frequencies mainly in the 2.2-2.6 MHz band are used. In addition, for detoxification of heavy metals and chemical substances, resonant frequencies mainly in the several hundred kHz band are used. Note that the target frequency may have some flexibility from the above desirable frequencies depending on the treatment content and the physical condition of the person receiving the treatment.

[0029] The frequency range division unit 121 divides a frequency range of a predetermined width into multiple stages (for example, 8) based on the target frequency set by the reference frequency setting unit 120. Specifically, The target frequency is f, w is the ratio of the frequency range relative to the target frequency. Let n be the number of stages. Let F(k) be the frequency of the k-th step in the frequency range division section 121. In that case, F(k) = f × (1 + w(n / 2 - k) / n) k = 0, 1, 2, ..., n 0.05% <w<3% It can be expressed as follows. Based on the above formula, a predetermined frequency range is divided into n steps of F(1), F(2), ..., F(n).

[0030] The frequency switching unit 122 sets multiple distinct frequencies divided by the frequency range division unit 121, and sets the frequency by switching between the multiple frequency stages in a loop at regular intervals, starting from a high frequency and gradually decreasing in order.

[0031] Specifically, the generated frequency F(k) consists of n+1 frequencies, which gradually decrease from a frequency w / 2(%) higher than the target frequency, pass the target frequency, and then, once it reaches a frequency w / 2(%) lower than the target frequency, repeat the fluctuation (wobble) from a frequency w / 2(%) higher than the target frequency to decrease again. Each frequency is generated at intervals of 50ms to 1s, preferably about 125ms.

[0032] For example, if the target frequency f is 2,000,000 Hz, w is 0.001 (0.1%), and n is 4, substituting 0, 1, 2, 3, and 4 for k yields five frequencies: 2,001,000 Hz, 2,000,500 Hz, 2,000,000 Hz, 1,999,500 Hz, and 1,999,000 Hz. These frequencies are emitted in descending order at 125 ms intervals, and when the frequency reaches 1,999,000 Hz, it returns to 2,001,000 Hz. In this way, the target frequency is wobbled by the repetition of these five frequencies.

[0033] The number of n can be set appropriately depending on the type of treatment. The frequency range division unit 121 may also calculate multiple stages of frequency based on the target frequency set in the reference frequency setting unit 120. Alternatively, a table registering the target frequency and multiple stages of frequency in association with the treatment purpose (treatment name) may be stored in the storage unit 13, and the reference frequency setting unit 120 may read the target frequency and the frequency range division unit 121 may read the multiple stages of frequency from this table. The treatment time may also be stored in this table in association with the treatment purpose.

[0034] The current output unit 123 generates a low-frequency current based on the frequency set by the frequency switching unit 122 and sends it through the electrode rods 20, 20. That is, when the user grips the electrode rods 20, 20 and activates the current generator 10, according to the example described above, five low-frequency currents of 2,001,000 Hz, 2,000,500 Hz, 2,000,000 Hz, 1,999,500 Hz, and 1,999,000 Hz are transmitted sequentially to the body through the electrode rods 20, 20. At this time, the user will feel a slight electrical stimulation in the hand gripping the electrode rods 20, 20.

[0035] Figures 3 to 5 are explanatory diagrams showing the waveforms of the low-frequency current output from the current output unit 123. Figure 3 shows the pulse waveform output at regular intervals, with Figure 3(a) showing a square wave and Figure 3(b) showing an inverted sawtooth wave. Figure 4(a) shows a decayed waveform where the amplitude decreases and converges to 0, with Figure 4(a) showing a decayed square wave and Figure 4(b) showing a decayed sine wave. Figure 5 shows the offset waveform obtained by offsetting the decayed square wave shown in Figure 4(a) in the positive direction, with Figure 5(a) showing the case with a 0% offset, Figure 5(b) showing the case with a 50% offset, and Figure 5(c) showing the case with a 100% offset.

[0036] By applying low-frequency currents of these waveforms to electrode rods 20, 20 and providing electrical stimulation to the user, experiments were conducted to determine the extent to which specific effects expected from the target frequency could be obtained. As a result, for all waveforms shown in Figures 3 to 5, a higher and more consistent effect was obtained when the target frequency was wobbled compared to when it was not wobbled.

[0037] In particular, various experiments revealed that the use of inverted sawtooth waves, shown in Figure 3(b), and attenuated waves, shown in Figure 4(b), is effective in causing pathogens to burst and die, as well as in detoxification. Furthermore, it was found that attenuated waves can provide effective stimulation in healing.

[0038] Furthermore, it was found that using attenuated waves suppresses the generation of frictional heat within cells, which is often seen when using square waves (pulse waves). Therefore, it was found that using attenuated waves eliminates the frictional heat effect, allowing the treatment to focus on the therapeutic effect of the target frequency. This effect was found to be particularly strong with attenuated square waves or inverted sawtooth waves compared to square waves (pulse waves). Note that inverted sawtooth waves are themselves attenuated waveforms and can be considered as attenuated waves.

[0039] Furthermore, although sine waves have a weaker impact force compared to square waves, using a damped sine wave as shown in Figure 4(b) further enhances the effect of eliminating the frictional heat effect. Note that the damped square wave and damped sine wave used in the experiment, as shown in Figure 4, have an amplitude that decreases exponentially over 8 wavelengths until it reaches zero, and the current values ​​from the 5th wavelength onward for both the damped square wave and the damped sine wave become considerably lower.

[0040] Furthermore, as a result of various experiments, we discovered that, as shown in Figure 5(a), using a waveform in which the attenuated square wave is offset in the positive direction, as shown in Figures 5(b) and 5(c), further enhances the expected effect depending on the target frequency, compared to using a waveform in which the attenuated square wave is not offset in the positive direction.

[0041] [Example of use of low-frequency treatment device 1] Next, we will explain an example of using the low-frequency treatment device 1. Figure 6 is an explanatory diagram showing an example of the display on the display unit 14 of the low-frequency treatment device 1. First, when the user turns on the power of the low-frequency treatment device 1, the treatment name and the function names of the three buttons that serve as the operation input unit 15 are displayed on the display unit 14, as shown in Figure 6(a). In the example shown in Figure 6(a), the treatment name "Hair Growth" and the function names of the three buttons "Back," "Start," and "Next" are displayed. In Figure 6(a), "1-1-30-4w" displayed on the display unit 14 indicates that the treatment will be performed once a day for 30 minutes for 4 weeks.

[0042] The user can press "Back" or "Forward" to switch between treatment names, such as "Wrinkle Removal" or "Immunity Boost." The user then displays the desired treatment name and presses the button corresponding to "Start." When the user presses the button corresponding to "Start" with the display unit 14 showing the information as shown in Figure 6(a), the target frequency for "Hair Growth" is set in the reference frequency setting unit 120, and a low-frequency current that wobbles flows through the electrode rods 20, 20 via the frequency range division unit 121, frequency switching unit 122, and current output unit 123. In this embodiment, the time for which the low-frequency current flows through the electrode rods 20, 20 is stored in the memory unit 13 in association with the treatment name. When the user presses the button corresponding to "Start," the time associated with the treatment name is set in a timer (not shown), and the timer starts counting. When the timer finishes counting the set time, the current output unit 123 stops outputting the low-frequency current to the electrode rods 20, 20. In this way, when the user presses the "Start" button with "Hair Growth" displayed on the display unit 14, a hair growth program is started, which applies a low-frequency current with a predetermined wobble frequency to the electrode rods 20, 20 for a set time. Similarly, if the user presses the "Start" button with another treatment name displayed on the display unit 14, the treatment program corresponding to that treatment name is started.

[0043] Next, we will explain specific usage examples with reference to Figure 7. As shown in Figure 7, the user grasps the central part of the left-hand electrode rod 20L with their left hand, grasps the central part of the right-hand electrode rod 20R with their right hand, and further places the end of the left-hand electrode rod 20L against their lower left abdomen and the end of the right-hand electrode rod 20R against their lower right abdomen.

[0044] When the current generator 10 sends current through the electrode rods 20, 20, electrical signals with a wobbling frequency are transmitted to the palms and lower abdomen, thereby providing electrical stimulation to the user's body. The palms are the most sensitive parts of the body, and by holding the left-hand electrode rod 20L with the left hand and the right-hand electrode rod 20R with the right hand, it becomes possible to transmit frequency signals to the body without interference from subcutaneous fat. Here, it is possible to transmit low-frequency currents with a wobbling frequency from the palms of both hands to the entire body, but the lower body is far from the palms, so it may not be possible to transmit the frequency signals sufficiently to the lower body. Therefore, the ends of the electrode rods 20, 20 on the side not connected to the cable 30 are brought into contact with the left and right lower abdomen. This makes it possible to transmit low-frequency currents to the lower body.

[0045] [Example of treatment using low-frequency therapy device 1] As described below, we investigated the effects of using low-frequency treatment device 1 on weight loss, wrinkle removal, hair growth, and atopic dermatitis. The common treatment settings in each example are as follows: • Generate a frequency signal with a wobble of approximately 0.05-0.5% above and below the target frequency. The wobble is applied by repeating from a high frequency to a low frequency. • Uses an attenuated wave as the waveform for the frequency signal. • Transmits the signal (wave) with most of it deflected (offset) to the positive side.

[0046] The results of the verification are as follows:

[0047] <Weight loss 1> The subject, a woman in her 50s named Ms. T, was relatively tall and did not appear particularly overweight. She weighed 60 kilograms and began a weight loss program using low-frequency electrical stimulation device 1, without engaging in any other activities such as dieting or exercise. As a result, weight decreased by 0.5 kg after one month, 1.0 kg after three months, and 1.5 kg after five months. Then, after extending the period and continuing the diet, I soon lost 2.0 kg, and occasionally even 2.5 kg, and sometimes even 3.0 kg. After 7 months, I continued to fluctuate between 2.0 kg and 3.0 kg for a while, but after 9 months, I surpassed 3.5 kg and 4.0 kg weight loss, and even reached 4.5 kg twice (55.5 kg). Thus, steady weight loss was observed through continued use.

[0048] <Weight Loss 2> When a woman in her 50s, different from Ms. T, underwent a weight-loss program using low-frequency treatment device 1, her hunger decreased after three months.

[0049] <Weight Loss 3> Mr. S, a man in his 50s who became a subject in this study, quit his job which involved a long commute, and reduced his outings to once a week, resulting in a significant decrease in his physical activity shortly before starting the weight loss program. On the other hand, his food intake increased, and his weight had risen to over 100 kilograms. It was predicted that he would gain even more weight if he continued this lifestyle. Under these circumstances, a weight loss program using low-frequency treatment device 1 was started, but soon the year-end and New Year's party season arrived. Mr. S loves beer, and although he only drinks 1 to 3 times a month, he drinks about 5 cans of 500ml beer each time. Clearly, the timing of starting the study was bad. However, Mr. S later confessed something unexpected. Coincidentally, the amount of alcohol he could drink had been halved, and even if he tried hard during the year-end and New Year's holidays, he could manage with about two-thirds of what he used to drink. Furthermore, his weight had not changed since mid-November. After that, Mr. S's lifestyle remained unchanged and his weight stayed the same, but about seven months after the start, a measurement revealed that he had lost 1 kilogram.

[0050] <Wrinkle removal 1> A wrinkle-removal program was administered to a woman in her early 60s. Figure 8 shows the changes in a subject who underwent treatment using the low-frequency treatment device 1. The program started in late September 2023, and as shown in Figure 8, a reduction in frown lines was observed after three months.

[0051] <Wrinkle Removal 2> A wrinkle-removal program using low-frequency treatment device 1 was performed on a woman in her late 40s. Figure 9 shows the changes in subjects who underwent treatment using the low-frequency treatment device 1. Three months after starting the wrinkle-reducing program, my weight hasn't changed, but my cheeks have become plumper. Two years prior to starting the program, my double eyelids had turned into triple eyelids, but four months after starting the wrinkle removal program, my left eyelid returned from triple to double eyelid, although it tended to revert to triple eyelids by the evening. Five months later, the skin around my eyes became firmer, the width of my double eyelids narrowed, and my left eye developed a double eyelid that remained. My right eyelid also returned to being a double eyelid.

[0052] <Hair growth 1> A hair regrowth program using low-frequency treatment device 1 was administered to a man in his late 50s. Figure 10 shows the changes in a subject who underwent treatment using the low-frequency treatment device 1. This man had extremely thin hair from his forehead to the crown of his head, and under the condition that he would not use scalp massage or hair growth / hair restoration products, he started a hair growth program using low-frequency treatment device 1. After about two months, he noticed that his hair was growing thicker after being pointed out by an acquaintance, and after continuing this hair growth program for one year, as shown in Figure 10, his hair from his forehead to the crown of his head increased by more than 30%.

[0053] <Hair growth 2> A hair regrowth program using low-frequency treatment device 1 was administered to a man in his late 50s. Figure 11 shows the changes in a subject who underwent treatment using the low-frequency treatment device 1. This man was concerned about thinning hair, mainly on the top of his head. The upper image in Figure 11 is from about 1 year and 2 months before the treatment. The man started the hair regrowth program in September of the following year. Perhaps because he had been growing his hair long, he continued the treatment but did not notice any changes for a long time. Then, after almost a year, a colleague pointed it out to him, and he finally realized that his hair had grown thicker. The lower image in Figure 11 is from about a year later, and as shown in the lower image in Figure 11, the top of his head, where his scalp was visible, is now covered with more hair, and the impression of thinning hair has been considerably reduced.

[0054] <Atopic dermatitis> Mr. T, a man in his 40s, had symptoms of chronic fatigue syndrome and brain fog, in addition to severe atopic dermatitis that he had suffered from since childhood. Therefore, Mr. T was given a treatment using low-frequency treatment device 1, in which a wobble was applied to the target frequency, the polarity was shifted to positive, and a damped wave was emitted for 50 minutes once a day. Two days after starting treatment, the pain from showering almost completely disappeared, and after about four days, the stinging sensation vanished. Bathing, which had been painful, became a pleasant experience. After about two months, my skin condition had almost fully recovered. As a healing reaction, a diuretic effect appeared immediately.

[0055] Furthermore, experimental results revealed that frequencies in the 2.2-2.6 MHz band can produce effects such as anti-aging, immune system enhancement, metabolism promotion, healing, and pathogen lethality. In addition, frequencies in the several hundred kHz band were found to have a detoxifying effect on heavy metals and chemical substances. This is thought to be because certain substances (heavy metals and chemical substances) in the body can be vibrated and broken down, allowing them to be expelled from the body.

[0056] [Effects and Effects] According to one embodiment of the present invention configured in this way, a low-frequency treatment device 1 performs a treatment on a user by applying a low-frequency current, and the user is given electrical stimulation by a low-frequency current in which the target frequency is oscillated (wobbled) within a predetermined frequency range. As a result, the effects that can be expected from the current of the target frequency, such as weight loss, wrinkle removal, and hair growth, become more apparent.

[0057] Furthermore, according to this embodiment, by utilizing attenuated waves, it is possible to suppress the generation of frictional heat within cells, which is often seen when using square waves (pulse waves). In this way, by utilizing attenuated waves, it is possible to eliminate the frictional heat effect and concentrate on the frequency effect.

[0058] Furthermore, according to this embodiment, by using a low-frequency current with a waveform offset in the positive direction, the effects expected from a current at the target frequency become more readily apparent.

[0059] Furthermore, according to this embodiment, by holding the left-hand electrode rod 20L and the right-hand electrode rod 20R with both hands and bringing the ends of the left-hand electrode rod 20L and the right-hand electrode rod 20R into contact with, for example, the lower left abdomen and the lower right abdomen, a low-frequency current with a wobbling frequency can be transmitted from the palms to the upper body. Moreover, the low-frequency current is transmitted not only to the upper body but also to the lower body, causing electrical stimulation to reach the entire body, and making it easier for the effects expected from a current of the target frequency to appear.

[0060] Furthermore, when performing treatments aimed at hair growth or wrinkle removal, it is not necessary to directly contact the electrode rods 20, 20 with the head or face; the effect can be obtained simply by holding the electrode rods 20, 20 directly with both hands, thus providing a more user-friendly low-frequency treatment device 1.

[0061] Although embodiments of the present invention have been described above, the embodiments of the present invention are not limited to those described above. For example, in the embodiments described above, the user specifies the name of the treatment, and the target frequency and wobble range are set based on the table. However, the user may input the target frequency and the number of divisions numerically, and the frequency of each stage within the wobble range may be calculated. The effect of the wobble is better when the order is descending, but it is also better when the order is ascending or alternating between ascending and descending than when only the target frequency is emitted. Furthermore, in the embodiments described above, the electrode rod 20 is made of a cylindrical metal rod, but it is not limited to that and may be L-shaped, and the shape can be set as appropriate, as can the material of the electrode rod.
