Summary of the Invention

Problems to be Solved by the Invention

[0005] Here, the face is a particularly noticeable part of the body, and it is preferable to obtain an effect remotely on the face.

[0006] However, Patent Document 1 and general low-frequency therapeutic devices act on the part to which the low-frequency therapeutic device is attached, and no remote effect is assumed.

[0007] In addition, in the lymphatic vessels, the lymph that runs through the hand (including the upper arm and forearm) and the lymph of the neck that connects to the face branch from the left and right main lymphatic ducts located in the collarbone. Therefore, with the method of Patent Document 2, even if stimulation is applied to the lymph of the hand, almost no effect on the face can be obtained.

[0008] If one attempts to stimulate the lymph that connects to the face in order to produce an effect on the face, it is necessary to stimulate the lymph that runs from the front to the side of the neck. However, when stimulating the lymph of the neck, if the common carotid artery, which serves as a blood pressure sensor and runs very close to the lymph of the neck, is stimulated, the blood pressure may fluctuate suddenly, possibly causing dizziness and unsteadiness. Therefore, stimulation of the lymph from the front to the side of the neck is suitable for pinpoint stimulation within a narrow range so as not to affect the blood vessels, and stimulation using a current pad having a predetermined size is not suitable.

[0009] Therefore, in view of the above circumstances, an object of the present invention is to provide a beauty device that can give an effect remotely to the face without causing any adverse effects even when stimulation is applied within a predetermined range.

Means for Solving the Problems

[0010] To solve the above problems, in one aspect of the present invention, one electrode that is attached onto the large intestine meridian of the upper arm or forearm of the user's body, the other electrode that is attached in an inner direction from the one electrode at a position arranged in a direction orthogonal to the longitudinal direction of the upper arm or the forearm or in an oblique direction from the orthogonal direction, and a main body portion that applies a current between the one electrode and the other electrode, are provided. The current applied by the main body is, as the first energization, a pulse group composed of a plurality of pulses of a first polarity having a frequency of 20 to 100 Hz, a peak current value of 1 to 20 mA, and a pulse width of 50 to 250 μs is energized for a predetermined period, and after a pause, as the second energization, a pulse group composed of a plurality of pulses of a second polarity having a frequency of 20 to 100 Hz, a peak current value of 1 to 20 mA, and a pulse width of 50 to 250 μs, which is different from the first polarity, is energized for the same predetermined period as the first energization, and the pause is repeated, thereby providing a beauty device.

Effect of the Invention

[0011] According to one aspect, in a beauty device, even if stimulation is given within a predetermined range, there is no adverse effect, and the effect can be remotely applied to the face.

Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following drawings, the same reference numerals are given to the same components, and redundant descriptions may be omitted.

[0014] The present invention relates to a beauty device to be attached to specific acupoints of the body, and particularly to a beauty device that remotely exerts a beauty effect on the face by being attached to the acupoints. The present invention also relates to a beauty device set having a beauty device and a case in which specific acupoints are shown.

[0015] The present invention also relates to a beauty method using a beauty device to be attached to specific acupoints of the body.

[0016] <Schematic Configuration> FIG. 1 is a diagram showing a state in which the beauty device 1 of the present invention is attached to the Large Intestine Meridian of Hand-Yangming and the Lung Meridian of Hand-Taiyin of a user. Here, the Large Intestine Meridian of Hand-Yangming is one of the main meridians, and hereinafter, it will be simply referred to as the Large Intestine Meridian. On the other hand, the Lung Meridian of Hand-Taiyin is one of the meridians, and hereinafter, it will be simply referred to as the Lung Meridian.

[0017] The beauty device 1 of the present invention is used by attaching two electrode pads 3 and 4 to the Large Intestine Meridian and the Lung Meridian, which are examples of meridians. One electrode pad 3 of the beauty device 1 of the present invention is preferably attached to an acupoint (also called a tsubo) on the Large Intestine Meridian, and more preferably, the acupoint is Shouwuli (see FIGS. 2 and 3).

[0018] <Large Intestine Meridian and Acupoints> FIG. 2 is an explanatory diagram of the Large Intestine Meridian. (a) is a diagram showing the Large Intestine Meridian with respect to the position of the bones of the upper limb, and (b) is a diagram showing the position of Shouwuli with respect to the position of the muscles and blood vessels. In this specification, Shouwuli refers to the position on the arm where the little finger is placed at the tip of the wrinkle formed when the elbow is bent, and the index finger hits when four finger breadths are aligned (see FIGS. 1 and 2).

[0019] One of the twelve regular meridians, the Large Intestine Meridian of Hand-Yangming (hereinafter simply referred to as the Large Intestine Meridian), as shown in Fig. 2(b), is a meridian that passes through the thumb side of the arm from the index finger to the side of the nose on the body surface. Thus, starting from the acupoints on the index finger, the Large Intestine Meridian ascends through the hand, forearm, and upper arm, and reaches the neck and cheek from above the collarbone, so an effect on the face is expected. Therefore, it is sometimes used for the treatment of diseases of the face, eyes, nose, mouth, teeth, and throat.

[0020] Therefore, based on the concepts of traditional Chinese medicine, the inventor considered a patch-type wearable device that remotely provides a beauty effect for the purpose of improving skin concerns such as skin tone, shape, sagging, and swelling on the face by providing optimal physical stimulation to acupoints, which are important points on the meridians.

[0021] By the way, if an electrode pad is directly attached to the Large Intestine Meridian on the face, makeup will come off. Therefore, considering the point that it is easy for the user to attach it at a position other than the face as the electrode attachment position, it is preferable to be on the Large Intestine Meridian on the upper arm or forearm.

[0022] In addition, there is a carotid artery running through the neck, which is related to life. Therefore, if a wide range of stimulation is performed with an electrode pad, there is a risk of causing discomfort. Also, in the arm, if thick blood vessels such as the brachial artery, radial artery, and ulnar artery are directly stimulated, the same symptoms may appear.

[0023] Therefore, considering safety so as not to directly stimulate thick blood vessels such as the carotid artery, brachial artery, radial artery, and ulnar artery even when stimulating with current application from an electrode pad having a predetermined range, the stimulation location is more preferably Shouwuli on the triceps brachii side of the upper arm.

[0024] Fig. 3 is a diagram showing the schematic structure of the radial nerve in the upper limb. As shown in Fig. 3, at the position of Shouwuli, the end of the inferior lateral brachial cutaneous nerve derived from the radial nerve exists. This nerve is responsible for the sensation of the skin.

[0025] Therefore, by stimulating the Shouwuli point on the upper arm with the beauty device 1 of the present invention, it is also possible to stimulate the nerve endings. Thus, the user wearing the beauty device 1 can easily sense the start and stop states of the current application through the nerves.

[0026] <Comparative experiment> Here, as described above, it was known that stimulating the Large Intestine Meridian as a general theory had some effects on the face. In particular, in order to investigate the specific relationship between the Shouwuli point of the Large Intestine Meridian and the face, a comparative experiment of stimulating the Shouwuli point with needles was conducted as a premise.

[0027] Figure 4 is a diagram showing the procedure of acupuncture stimulation at the Shouwuli point in the comparative experiment. The acupuncture stimulation was performed on 4 subjects (N = 4) by an acupuncturist who is qualified for acupuncture treatment.

[0028] In the flow of the comparative experiment shown in Figure 4, first, in step S91, the acupuncturist performing the treatment discovers (finds) the position of the Shouwuli point, which is one of the acupoints of the subject.

[0029] In step S92, the acupuncturist inserts the needle into the Shouwuli point.

[0030] In step S93, the acupuncturist performs a twirling movement (needle twirling) of rotating the needle in one direction (for example, clockwise).

[0031] Thereafter, needle retention is performed with the needle inserted for a predetermined period (for example, 5 minutes) (step S94).

[0032] After 5 minutes, the acupuncturist removes the needle from the subject (step S95) and ends.

[0033] Figure 5 shows the change in the facial shape of one of the subjects. In Figure 5, from left to right, the facial states of the same person are shown: (a) before acupuncture stimulation, (b) immediately after acupuncture stimulation, and (c) 20 minutes after acupuncture stimulation.

[0034] As shown in the photograph of Fig. 5, it can be seen that compared with the state before acupuncture stimulation in (a), immediately after acupuncture stimulation in (b), and 20 minutes after acupuncture stimulation in (c), the sagging of the subject's skin gradually disappeared and the contour became sharp.

[0035] Fig. 6 shows the average value of the change in the brightness (L*) of the faces of four subjects. In Fig. 6, the vertical axis represents L* (brightness: luminance). The value of the brightness L* was measured with a spectrophotometer (manufactured by Konica Minolta).

[0036] On the horizontal axis of Fig. 6, from left to right, the L* values of the face brightness before acupuncture stimulation, immediately after acupuncture stimulation, and 20 minutes after acupuncture stimulation are shown. As can be seen from the graph, the brightness L* increased immediately after acupuncture stimulation compared to before acupuncture stimulation, and furthermore, as time passed after the acupuncture stimulation, the brightness L* increased even more compared to immediately after the acupuncture stimulation. The increase in the brightness L* means that the skin color of the face changed in the brighter direction.

[0037] Therefore, from the experiment in Fig. 4 above, it was clarified that by performing acupuncture stimulation on Shouwuli, as shown in Figs. 5 and 6, there is an effect of sharpening the shape of the face and brightening the skin color of the face after the stimulation and after the passage of time from the stimulation.

[0038] Based on this effect, the inventor examined and studied whether the same effect can be given without needles by performing transcutaneous electrical nerve stimulation (TENS) at the same location.

[0039] Here, when applying TENS, it is necessary to apply current at two points, the positive electrode and the negative electrode. Therefore, the following examination was conducted on the body part to be stimulated together with Shouwuli.

[0040] <Lung Meridian> Fig. 7 is an explanatory diagram of the Lung Meridian on the arm. (a) is a diagram showing the Lung Meridian with respect to the position of the bone, and (b) is a diagram showing the position of the Lung Meridian with respect to the position of the muscle and blood vessel.

[0041] Assuming that the beauty device 1 having two electrode pads 3 and 4 is to be attached, the inventor focused on the lung meridian in addition to the large intestine meridian.

[0042] Meridians are connected to organs and regulate the functions of those organs. The lungs not only play a role in breathing but also send body fluids (jinye) throughout the body and reach the skin. Therefore, its state affects the skin and body hair. Also, the lungs and the large intestine have a close relationship. When constipated, there are often eruptions. This is because the lung meridian and the large intestine meridian are directly connected and further connected to both the lungs and the large intestine. Therefore, it is expected that stimulating the acupoints on the large intestine meridian will affect the lungs and improve the skin condition.

[0043] Therefore, considering that the other electrode pad 4 of the beauty device 1 of the present invention is thicker than the forearm and easier to attach, it is attached closer to the body side (inside) than the one electrode pad 3. In this embodiment, an experiment was conducted on the case where the electrode pad 4 is attached on the lung meridian extending to the biceps brachii side of the upper arm. Note that the one electrode pad 3 and the other electrode pad 4 may be attached at positions arranged in a direction perpendicular to the longitudinal direction of the arm (upper arm or forearm) or in an oblique direction from the perpendicular direction.

[0044] As shown in FIG. 7, the upper end of the lung meridian is around the collarbone, and there are main lymphatic vessels around the collarbone. Also, as shown in FIG. 7(b), thick blood vessels such as the brachial artery, radial artery, and ulnar artery run through the upper limb.

[0045] Therefore, even when stimulating with current application from the electrode pads 3 and 4 having a predetermined range, it is preferable that the other stimulation site is the lung meridian, which is known to exert an effect in cooperation with the large intestine meridian, so as not to stimulate the main lymphatic vessels or thick blood vessels such as the radial artery and ulnar artery.

[0046] <Configuration of the beauty device> FIG. 8 is an external view of the beauty device 1 according to an embodiment of the present invention.

[0047] The beauty device 1 of the present invention has a main body 2 and two electrode pads (an example of electrodes) 3 and 4.

[0048] In the beauty device 1 of the present invention, by performing TENS on the skin via the electrode pads 3 and 4, an effect similar to that shown in FIGS. 4 and 5 is provided without using needles.

[0049] In the beauty device 1, the electrode pads 3 and 4 are parts that apply a current for nerve stimulation to the skin, and the main body 2 is a part that generates a current and applies it to the electrode pads 3 and 4.

[0050] The configuration of the main body 2 will be described below with reference to FIGS. 9 and 10. FIG. 9 is an exploded view of the main body of the beauty device shown in FIG. 8.

[0051] The main body 2 has a top case 21, a bottom case 22, spring hooks 23 and 24, an electronic board 25, an operation button 26, and an inner case 27.

[0052] The top case 21 and the bottom case 22 are cases that protect the entire main body 2 from above and below.

[0053] The control unit 51 and the like shown in FIG. 10 are mounted on the electronic board 25. In addition, a display unit 28 for displaying the situation of current application is provided on the electronic board 25.

[0054] The spring hooks 23 and 24 are pad support parts that engage with and hold the electrode pads 3 and 4 on the lower side. A hole through which a part of the spring hooks 23 and 24 penetrates is formed in the lower surface of the bottom case 22, and the spring hooks 23 and 24 inserted through the hole fix the electrode pads 3 and 4 to the bottom case 22.

[0055] In addition, a notch 220 is formed on the side surface of the bottom case 22, and in the assembled state, a part of the operation button 26 is exposed from this notch 220, enabling the user to operate the operation button 26.

[0056] The inner case 27 is a case that protects the electronic substrate 25 and is provided inside the top case 21.

[0057] FIG. 10 is a control block diagram on the electronic substrate 25 of the beauty device 1 of the present invention.

[0058] As a circuit, the electronic substrate 25 has a control unit 51, a power supply unit 52, an output waveform generation unit 53, a sensing unit 54, and two electrode connection terminals 55, 56. Further, the operation button 26 and the display unit 28 shown in FIG. 9 are mounted on the electronic substrate 25.

[0059] The control unit 51 controls the waveform. Further, the control unit 51 transmits the operation start information from the operation button 26 to the power supply unit 52, and starts the supply of power from the power supply unit 52 to the control unit 51 and the sensing unit 54.

[0060] The sensing unit 54 is a sensor that detects the output value of the output waveform generation unit 53 and detects that the electrode pads 3, 4 have been peeled off from the skin.

[0061] The output waveform generation unit 53 generates a current having a pulse group described later and outputs it intermittently. Then, the generated current is applied to the electrode pads 3, 4 via the electrode connection terminals 55, 56.

[0062] The two electrode connection terminals 55, 56 are terminals that connect to the two electrode pads (also referred to as current pads, patches) 3, 4 via the two spring hooks 23, 24.

[0063] The operation button 26 is a switch that instructs on / off of driving. Further, when a plurality of modes are set in the beauty device 1, the operation button 26 also functions to select a mode.

[0064] The display unit 28 is composed of a light emitting means such as an LED (Light Emitting Diode), and emits light to indicate that it is being driven during the driving period.

[0065] Alternatively, it emits light to indicate that the driving period has ended. Note that when a notification during driving is not required, the display unit 28 may not be provided.

[0066] Alternatively, instead of visual display by light, it may be configured to notify by voice indicating the end of driving. In the case of voice notification, a voice output unit may be provided instead of the display unit 28. Further, instead of visual display by light, it may be configured to notify by vibration indicating the end of driving. In the case of vibration notification, a vibration output unit may be provided instead of the display unit 28.

[0067] Note that although the portable beauty device in which the two electrodes and the main body are connected has been described with reference to FIGS. 8 to 10, the beauty device of the present invention may be a stationary beauty device that connects the two electrodes and the main body by wire or wirelessly.

[0068] <Examination of waveform> Here, in the beauty device 1 of the present invention, the waveform generated by the output waveform generation unit 53 and applied to the meridians of the skin via the electrode pads 3 and 4 will be described.

[0069] FIG. 11 shows an example of the waveform of a pulse group of the current applied to the skin at the electrode pads 3 and 4 of the beauty device 1 of the present invention.

[0070] The current (waveform) applied by the output waveform generation unit 53, as a first energization, energizes a pulse group (cluster wave) having a plurality of pulses (fundamental waves) of a first polarity (positive polarity) for a predetermined period, and then pauses for a predetermined period. Thereafter, as a second energization, a pulse group having pulses of a second polarity different from the first polarity (negative polarity in FIG. 11) is energized for the same predetermined period as the first energization, and the process of pausing is repeated.

[0071] In this specification, the period of energizing the pulse group refers to the period during which the envelope connecting the peak values of the plurality of pulses constituting the pulse group maintains a value other than 0.

[0072] Here, the pulse that is the fundamental wave constituting the pulse group to be applied, as shown in FIGS. 11(a), (c), and (d), is, as shown in the enlarged view of FIG. 11(b), for example, a rectangular wave with a pulse width of 200 μs. This pulse width was set with reference to the pulses applied by a general low-frequency therapeutic apparatus. Note that the pulse width is not limited to 200 μs and may be 20 to 250 μs.

[0073] Also, the peak value (also referred to as the amplitude value or peak current value, hereinafter referred to as the peak value), which is the maximum wave height value of the plurality of pulses included in the pulse group to be applied as shown in FIG. 11, is 10 mA. This peak value is the peak value set based on Example 2 described later. Note that the peak current value may be 1 to 20 mA.

[0074] Also, the drive frequency of the plurality of pulses included in the pulse group to be applied as shown in FIGS. 11(a), (c), and (d) is 40 Hz. This frequency is the frequency set based on Example 3 described later. When driving at a frequency of 40 Hz, as shown in FIG. 11(b), the ON / OFF of the pulses is repeated with a pulse period of 25 ms to create a pulse group that is a clustered wave. Note that the drive frequency may be 20 to 100 Hz.

[0075] In FIGS. 11(a), (c), and (d), in any waveform, as the first energization, a pulse group of the first polarity (positive electrode (+ electrode)) is energized for 2 seconds and then paused for 1 second, that is, maintained in a non-applied state. As the second energization, a pulse group of the second polarity (negative electrode (- electrode)) is energized for 2 seconds and then paused for 1 second, and an example of repeating this is shown. The optimum values of this energization period and pause period are the periods set based on Example 4 described later.

[0076] In these energizations, by changing the polarity of the pulse that is the fundamental wave, waveforms of pulse groups of plus (positive electrode) and minus (negative electrode) are generated.

[0077] In Fig. 11(a), in the first energization and the second energization, an example is shown in which the amplitudes and frequencies of a plurality of pulses constituting the applied pulse group are constant during a predetermined period, and thus the pulse group becomes a rectangular wave as a whole. Specifically, as shown in Fig. 11(b), by repeatedly applying a pulse, which is a fundamental wave, with a constant amplitude, the pulse group becomes a rectangular wave as a whole. Also, the waveform in Fig. 11(a) is an envelope connecting the peak values of a plurality of pulses and has a rectangular outer shape.

[0078] In Fig. 11(c), during the periods of the first energization and the second energization, the amplitude of a plurality of pulses constituting the applied pulse group is 0 at the beginning of the energization period (predetermined period), gradually increases, reaches the maximum value at the center of the period, gradually decreases, and finally becomes 0. The amount of change in the amplitude at this time is large at the beginning and the end and small near the center. As a result, the waveform in Fig. 11(c) is an envelope connecting the peak values of a plurality of pulses and has a sine wave outer shape, that is, the outer shape of the pulse group becomes a sine wave.

[0079] In Fig. 11(d), in the first energization and the second energization, the amplitude of a plurality of pulses constituting the applied pulse group is 0 at the beginning of the energization period (predetermined period), gradually increases, reaches the maximum value at the center of the period, gradually decreases, and finally becomes 0. The amount of change in the amplitude at this time is constant. As a result, the waveform in Fig. 11(d) is an envelope connecting the peak values of a plurality of pulses and has a triangular wave outer shape, that is, the outer shape of the pulse group becomes a triangular wave.

[0080] The driving period for repeatedly energizing and stopping the electrode pads 3 and 4 with these waveforms is 5 to 15 minutes, and after driving, it automatically stops and notifies.

[0081] <<Comparative Study of Waveforms>> Here, the present inventor conducted the following comparative investigation to appropriately select the type of waveform (pulse group) and the energization period that stimulate the Shouryuri and give a remote effect to the face.

[0082] <Example 1> The inventor pasted current patches respectively, applied a plurality of waveforms with different types of pulse train waveforms, that is, waveforms with different outer shapes of pulse envelopes, and compared and investigated the remote effects on the face when stimulating Shouwuli.

[0083] FIG. 12 is a graph showing the change rate of blood flow in the cheek when a pulse train with a waveform having a different outer shape of the envelope is applied. In FIG. 12, the horizontal axis represents time, and the vertical axis represents the change rate of blood flow in the cheek of the face when the value before current application is set to 100%.

[0084] Here, the subject washed the arm, rested for 10 minutes in the supine position, continued the stimulation for 5 minutes in the supine position, and then rested for 15 minutes. Then, during the periods of rest before stimulation, during stimulation, immediately after stimulation to 5 minutes after stimulation, 5 minutes after stimulation to 10 minutes after stimulation, and 10 minutes after stimulation to 15 minutes after stimulation, the blood flow in the cheek of the face was measured. In the comparative investigations of measuring the blood flow in the cheek of the face shown in FIGS. 13 to 15 and FIG. 20, the measurement was also performed in the same manner. In the experiments (Examples 1 to 5, 9) shown in FIG. 12 and FIGS. 13 to 15 and FIG. 20 described later, the blood flow in the cheek of the face was measured using a laser blood flow meter (manufactured by OMEGAWAVE, Omega Flow FLO-N1).

[0085] In this example, the experiment administrator pasted the electrode pads 3 and 4 of the beauty device 1 on the Shouwuli and the Lung Meridian on the left arm of the subject, respectively, and measured the changes in the blood flow in the left and right cheeks of the face.

[0086] In this example, a rectangular wave and a sine wave current with a peak value of 10 mA were applied to 6 subjects, and a rectangular wave and a sine wave with a peak value of 5 mA were applied to 5 subjects, so as to obtain data on the left and right cheeks. Therefore, for both the rectangular wave and the sine wave with different outer shapes of the waveform, 22 data for 11 people were obtained, and the average value is shown.

[0087] In this example, in common for each condition, the pulse amplitude of a plurality of pulses constituting the applied pulse train is 200 μs, the frequency is 40 Hz, and the pulse train is a pattern of repeating energization for 2 seconds and rest for 1 second.

[0088] In FIG. 12, regardless of whether the outer shape of the pulse group is a rectangular wave or a sine wave, there are some differences in the magnitude of the effect, but an effect is obtained in any case compared to before application. Therefore, waveforms with outer shapes of rectangular waves and sine waves of the pulse group can be applied to the waveform having the pulse group applied by the beauty device of the present invention. Further, for a triangular wave whose outer shape is similar to that of a sine wave, a similar effect can be expected, so it can be applied to the pulse group applied by the beauty device of the present invention.

[0089] Furthermore, from FIG. 12, it can be seen that the effect appears more easily in the rectangular wave than in the sine wave in terms of the overall outer shape of the pulse group waveform. Therefore, for the pulse group during the energization period at the positive or negative electrode, when the peak value of the pulse is constant and the outer shape is a rectangular wave, the effect appears greatly and is suitable.

[0090] <Example 2> The inventor pasted pads with different peak values (peak current values) of the current of each pulse constituting the pulse group to be applied and stimulated the inner forearm to comparatively investigate the remote effect on the face.

[0091] FIG. 13 is a graph showing the change in blood flow in the cheek when the pulses constituting the pulse group have different peak values. In FIG. 13, the horizontal axis represents time, and the vertical axis represents the change rate of the blood flow in the cheek of the face when the value before current application is set to 100%.

[0092] In this example, for each of the four subjects, a current with the peak value of the pulse set to 5 mA, 10 mA, 15 mA, and 20 mA was applied, and data on the left and right cheeks were acquired. Therefore, the value at each peak value is the average value of eight pieces of data.

[0093] And in this example, in common for each condition, the pulse amplitude of the plurality of pulses constituting the pulse group to be applied is 200 μs, the frequency is 40 Hz, and the pulse group is a pattern that repeats energization for 2 seconds and pause for 1 second.

[0094] In addition, as shown in the embodiment of FIG. 12, since the overall outer shape of the pulse train waveform is preferably rectangular, the peak current values (amplitudes) of the plurality of pulses constituting the applied pulse train are made constant.

[0095] FIG. 13 shows that even if the peak value of the applied pulse is 5 mA, 10 mA, 15 mA, or 20 mA, although there are slight differences in the magnitude of the effect, an effect is obtained in all cases compared to before application. Therefore, a plurality of pulses with peak values of 5 to 20 mA can be applied to the pulse train applied by the beauty device of the present invention.

[0096] Also, when the peak value of the pulse was 5 mA, 10 mA, or 15 mA, the subject hardly felt any stimulation, but when it was 20 mA, the subject felt a little stimulation.

[0097] Furthermore, as shown in FIG. 13, when a pulse train composed of pulses having a peak value of 10 mA is applied, the current amount in the cheek increases the most. Therefore, it is more preferable that the peak value of each pulse is around 10 mA, for example, about 7 to 13 mA.

[0098] <Example 3> The inventor applied a plurality of pulse trains with the frequencies of the plurality of pulses being changed to the pads attached to the hand and forearm, and comparatively investigated the remote effects on the face.

[0099] FIG. 14 is a graph showing the change rate of the blood flow volume in the cheek when the frequencies of the plurality of pulses constituting the pulse train are changed. The horizontal axis in FIG. 14 represents time, and the vertical axis represents the change rate of the blood flow volume in the cheek of the face with the value before current application being set as 100%.

[0100] In this embodiment, the frequencies of the plurality of pulses constituting the pulse train were set to 20 Hz, 40 Hz, and 100 Hz, and the left and right data of 4 subjects were acquired. Therefore, the value at each frequency is the average of 8 data.

[0101] Reflecting the results of FIGS. 12 and 13, in this embodiment, under each condition, a pulse group with a peak value of the waveform set to a constant 10 mA and a rectangular outer shape was applied. Also, the pulse width of each of the plurality of pulses constituting the pulse group was set to 200 μs, and a pulse group with a pattern of repeating energization for 2 seconds and pause for 1 second was applied.

[0102] In FIG. 14, regardless of whether the frequency of each of the plurality of pulses constituting the pulse group is 20 Hz, 40 Hz, or 100 Hz, although there are some differences, effects are obtained in all cases compared with before application. Therefore, 20 to 100 Hz can be applied as the frequency of each of the plurality of pulses constituting the pulse group to the beauty device of the present invention.

[0103] Furthermore, as shown in FIG. 14, when a current of a waveform having a pulse group driven at a frequency of 40 Hz of each of the plurality of pulses constituting the pulse group is applied, the amount of current in the cheek increases the most. Therefore, it is preferable to set the frequency of each of the plurality of pulses constituting the pulse group around 40 Hz. The range around 40 Hz of the frequency of each of the plurality of pulses constituting the pulse group is more preferably, for example, about 30 to 60 Hz.

[0104] <Example 4> The inventor of the present invention pasted pads with changed energization periods and pause periods of the applied pulse group to stimulate the Shouwuli point and comparatively investigated the remote effects on the face.

[0105] FIG. 15 is a graph showing the change rate of the blood flow volume in the cheek when the energization period and the pause period are changed. In FIG. 15, the horizontal axis represents time, and the vertical axis represents the change rate of the blood flow volume in the cheek of the face with the value before current application set to 100%.

[0106] In this embodiment, the interval between each energization and pause of the pulse group was set to a repeating pattern of energization for 2 seconds and pause for 1 second, a repeating pattern of polarity-reversing energization every 3 seconds, and a repeating pattern of energization for 1 second and pause for 2 seconds, and applied to the subject.

[0107] In the repeating pattern of 2 - second energization and 1 - second rest, and the repeating pattern of 1 - second energization and 2 - second rest, as shown in Fig. 11, the first energization and the second energization have different polarities (positive electrode, negative electrode) and there is a rest period between the energizations.

[0108] In the repeating pattern of polarity - reversed energization every 3 seconds, it repeats energizing for 3 seconds, reversing the polarity and then energizing for 3 seconds (switching the polarity every 3 seconds of energization), and there is no rest period.

[0109] In this embodiment, since data of the left and right cheeks of three subjects were acquired, each value is the average value of six data.

[0110] Also, from the comparative investigation in Figs. 11 - 14, since the overall outer shape of the pulse group waveform is preferably rectangular, in this embodiment, in common for each condition, the pulse group is driven at a frequency of 40 Hz with the peak current value (amplitude) of a plurality of pulses constituting the applied pulse group fixed at 10 mA. Also, the pulse width of a plurality of pulses constituting the pulse group is set to 200 μs.

[0111] From Fig. 15, when a waveform composed of 2 - second pulse group ON and 1 - second rest period is repeatedly applied, the blood flow in the cheek increases the most. Therefore, the ON / OFF interval of the pulse group is preferably 2 - second pulse group ON and 1 - second rest period.

[0112] Here, in Fig. 15, in the interval between energization and rest, in any of the applied patterns of 2 - second energization and 1 - second rest, 3 - second polarity - reversed energization every 3 seconds, and 1 - second energization and 2 - second rest, there are some differences in the magnitude of the effect, but an effect is obtained in all cases compared with before application. However, the pattern of polarity switching every 3 seconds without a rest period has a significantly lower effect compared with the patterns of 2 - second energization and 1 - second rest, and 1 - second energization and 2 - second rest. Therefore, it is obvious that it is more effective to provide a rest period when switching the polarities of the positive and negative electrodes of the pulse.

[0113] Also, when comparing the pattern of energization for 2 seconds and rest for 1 second with the pattern of energization for 1 second and rest for 2 seconds, the effect is greater when energizing for 2 seconds and resting for 1 second. Therefore, in the applied pattern of energization and rest, it is preferable to set the energization period longer than the rest period.

[0114] Note that the applied pattern of energization and rest does not necessarily have to be limited to the pattern of energization for 2 seconds and rest for 1 second shown in this example. For example, a current having an intermittent pulse group in which the periods of energization and rest are 1 second to 4 seconds of energization and 0.5 to 2 seconds of rest period, and the energization period is set to be equal to or longer than the rest period, can be applied to the current applied by the beauty device of the present invention. With such a setting, it is considered that the same effect as the pattern of energization for 2 seconds and rest for 1 second can be obtained.

[0115] <Example 5> FIG. 16 is a graph showing the change in the blood flow volume of the cheek when the electrode pads 3 and 4 of the beauty device 1 of the present invention are attached to Shouwuli and the Lung Meridian and driven for 10 minutes.

[0116] In this example, in the pulse group in which the overall outer shape of the waveform is a rectangular wave, which was the condition with a large effect in the comparative measurements of Examples 1 to 4, the amplitudes of the plurality of pulses are 10 mA, the pulse width is 200 μs, and the frequency is 40 Hz. The pulse group has a pattern of energization for 2 seconds and rest for 1 second as the "set condition" of the current.

[0117] Using the beauty device 1, the current of the pulse group under the above set conditions was applied and stimulated to the Shouwuli and the Lung Meridian of three seated subjects for 10 minutes. Then, immediately before and immediately after the stimulation, the blood flow of the cheek of the face was measured using a laser speckle flowmeter (LSFG: Laser Speckle FlowGraphy). The vertical axis in FIG. 16 is the blood flow value, and the value is the average value of the three subjects.

[0118] Here, the blood flow value measured by LSFG (also referred to as the blood flow evaluation value) is the MBR (Mean Blur Rate), which represents the average blur rate. When taking a photo, the image of an object moving quickly blurs, but the blood flow value is a quantification of this blur rate and is proportional to the moving speed of blood cells. Therefore, the blood flow value (MBR) in this measurement is an index and no unit is provided.

[0119] As shown in FIG. 16, when applying a current under the set conditions using the actual beauty device 1, it can be seen that the blood flow value increases. And when applying a current under the above set conditions in the beauty device 1, three subjects did not feel the stimulation of the current.

[0120] In this embodiment, the driving period of repeatedly turning on (starting the device) and off (stopping the device) is set to 10 minutes, but the driving period may be 5 to 15 minutes. Note that after the end of the 10 - minute driving period, the application of the current automatically stops.

[0121] Thus, even when applying a current having the above - mentioned set conditions and other condition pulse groups to the Hotei point and along the Lung Meridian by the beauty device 1 of the present invention, there are no adverse effects such as discomfort, and the effect on the face can be obtained remotely.

[0122] <Example 6> The inventor measured the effect when applying a current by attaching the electrode pads 3 and 4 of the beauty device 1 of the present invention to the Hotei point and along the Lung Meridian from the perspective of the autonomic nerve.

[0123] FIG. 17 is a graph showing the change in the autonomic nerve when the electrode pads of the beauty device of the present invention are attached to the Hotei point and along the Lung Meridian and driven for 10 minutes.

[0124] Using the beauty device 1, a current having the above - mentioned set - condition pulse group was applied and stimulated for 10 minutes to the Hotei point and along the Lung Meridian of three seated subjects.

[0125] Then, for three subjects sitting in the seat, for 10 minutes before the stimulation, 10 minutes during the stimulation, 10 minutes immediately after the stimulation, and 10 to 20 minutes after the stimulation, the sympathetic and parasympathetic nerves in the autonomic nervous system were measured using a Radar Circ (Nihon Kohden Corporation), a multifunctional monitor electrocardiograph with an analysis function.

[0126] Specifically, in the analysis software within the Radar Circ, the electrocardiogram waveform was measured, and the time-series data waveform obtained by plotting the R-R intervals for each heartbeat obtained from the electrocardiogram for 5 minutes was calculated. Then, frequency analysis was performed on the time-series data waveform (schematic diagram) of the R-R intervals, and the sympathetic nerve activity and parasympathetic nerve activity were indexed by separating and extracting them into slow waves (low-frequency band) and fast waves (high-frequency band).

[0127] For example, in the time-series data waveform of the R-R intervals, waves that vary rapidly and are in the high-frequency band (0.15 - 0.5 Hz) (HF) indicate parasympathetic nerve activity, and the ratio of the low-frequency band (0.04 - 0.15 Hz) (LF) to the high-frequency band (HF) is analyzed to indicate sympathetic nerve activity.

[0128] The numerical values on the vertical axis in FIG. 17 are indicators showing the parasympathetic nerve activity and sympathetic nerve activity analyzed from the heartbeats within the device as described above, and there is no unit.

[0129] The vertical axis in FIG. 17 represents the numerical values of the sympathetic and parasympathetic nerves. The values are the average values of three subjects.

[0130] As shown in FIG. 17, compared with before the stimulation by the current, the numerical value of the sympathetic nerve increased (acted actively) immediately after the stimulation, and further, 10 minutes later and 20 minutes later, the sympathetic nerve increased step by step. On the other hand, the parasympathetic nerve did not change.

[0131] Here, the sympathetic nerve is the nerve that is the source of active movements during the day, and the parasympathetic nerve is the nerve when sleeping or relaxing. Therefore, by stimulating the Shouwuli and the upper part of the Lung Meridian with the beauty device 1 of the present invention and activating the sympathetic nerve, the whole body becomes active.

[0132] Thus, in the beauty device of the present invention, by applying electrical stimulation to Shouwuli, which is an acupuncture point, and the Lung Meridian, which is a meridian, the body is activated like the activities during exercise from a remote site, leading the state of the face and the whole body to a better state. As effects on the face and the whole body, in addition to the above-described effect of increasing blood flow volume, improvement of swelling and relaxation effect on the body can be expected.

[0133] <Example 7> The inventor investigated the effect of improving facial swelling when the electrode pads 3 and 4 of the beauty device 1 of the present invention were attached to Shouwuli and the Lung Meridian and a current was applied.

[0134] FIG. 18 is a diagram for explaining the measurement positions of the face when measuring the change amount of the face line in Example 7. FIG. 19 is a graph showing the change rate of the distance between the indices of the face at the positions shown in FIG. 18 when a current having the pulse group of the above-described set conditions was applied for 10 minutes with the electrode pads 3 and 4 of the beauty device 1 of the present invention attached to Shouwuli and the Lung Meridian.

[0135] In this example, a method for setting an index of the change amount of the contour around the jaw, which is a reference for the change amount of the face, will be described. In this example, based on the 3D data captured using 3dMD (manufactured by 3dMD), which is a three-dimensional surface ultra-high-speed imaging and analysis system, the distance between the indices of the face is measured by the following method. (1) As shown in FIG. 18, fixed indices (moles or scars) are determined one by one around the mouth and on the neck. For a person without indices, for example, small stickers are attached at two points on the cheek and the neck. (2) The 3D captured data before and after the stimulation are respectively input into the analysis software, and the surface distance between the two points and the straight-line distance between the two points are respectively calculated. (3) By dividing the surface distance by the straight-line distance, the numerical changes before and after the stimulation are compared. (4) The values before and after the stimulation are compared.

[0136] The rate of change of the distance set by the above method is shown in FIG. 19. In this embodiment, measurements were taken for nine subjects in the seated state. However, for the right side, since accurate measurement could not be performed for one person, the numerical values on the right side are the average values of eight people, and the numerical values on the left side are the average values of nine people.

[0137] In FIG. 19, the distance between two indicators on the cheek and the neck before current application is set to 1, and the distance between the indicators immediately after applying current for 10 minutes is shown as a ratio to the distance between the indicators before current application. Note that Before indicates immediately before the stimulus, and After indicates 20 minutes after the stimulus.

[0138] As shown in FIG. 19, it can be seen that on both the right side and the left side, the distance between the indicators on the face and the neck has become shorter, that is, the boundary of the face line (the jaw line of the face contour) has become clear and sharp.

[0139] Thus, in the beauty device 1 of the present invention, by applying electrical stimulation to Shouwuli, which is an acupoint, and on the Lung Meridian, which is a meridian, it is possible to remotely improve facial swelling and sagging (also called flabbiness), and has the effect of making the face smaller.

[0140] <Example 8> In order to investigate the effect when the electrode pad is attached to Shouwuli and current is applied, the present inventor conducted a comparative measurement by comparing with the case where the electrode pad is attached to a location other than the meridian on the arm.

[0141] FIG. 20 shows a comparison of the change in facial blood flow when the electrode pad of the beauty device of the present invention is attached to Shouwuli and on the Lung Meridian, and when it is attached to the upper arm other than the meridian, when driven for 5 minutes.

[0142] In this embodiment, similar to the above Examples 1 to 5, the subject washed the arm, rested supine for 10 minutes, then continued the stimulation for 5 minutes in the supine state, and rested for 15 minutes. Then, during the period before the stimulus, during the stimulus, immediately after the stimulus to 5 minutes after, 5 minutes after the stimulus to 10 minutes after, and 10 minutes after the stimulus to 15 minutes after, the blood flow in the cheek of the face was measured. FIG. 20 shows the data of the left and right cheeks of three subjects, and each numerical value is the average of six data.

[0143] Also, in this embodiment, for both the case of attaching to Shouwuli and the lung meridian and the case of attaching to a site other than the meridian on the upper arm, in Examples 1 to 5, a current having the pulse group of the above-mentioned setting conditions with high effects was applied.

[0144] In FIG. 20, as shown by the dotted line, when the beauty device 1 of the present invention is attached to the proximal dorsal side of the upper arm other than the acupoint and a current having the pulse group of the above-mentioned setting conditions is applied, the blood flow in the cheek is reduced after the stimulation. Thus, even when the beauty device 1 applies a current stimulation to a site other than the acupoint, the effect of increasing the blood flow in the face cannot be obtained.

[0145] On the other hand, as shown by the solid line in FIG. 20, when attached to Shouwuli, which is an acupoint, and stimulated by an electric current, it can be seen that the blood flow in the cheek of the face has increased compared to before the stimulation.

[0146] Thus, the place where the effect can be obtained remotely is not any stimulation site, but it is necessary to stimulate specific meridians or acupoints such as Shouwuli and the lung meridian. Only when specific meridians and acupoints are stimulated, a remote effect on the face and the whole body can be obtained.

[0147] <Position display of Shouwuli> In the measurement of the comparative investigation effect of the acupuncture stimulation related to the above comparative experiment and the electric current stimulation by the beauty device 1 on the subject, since the practitioners such as acupuncturists and experiment administrators knew the positions of the acupoints (Shouwuli) and meridians, they could stimulate the correct positions. However, the beauty device 1 of the present invention is preferably used at home by the user himself / herself by attaching it to the correct acupoint position.

[0148] Therefore, it is preferable that a case or the like is provided with a display indicating the positions of Shouwuli and the lung meridian.

[0149] FIG. 21 is a diagram showing the beauty device 1 of the present invention and a case 6 in which the beauty device 1 is housed. In the present embodiment, the beauty device 1 and the case 6 constitute a beauty device set 10.

[0150] As shown in FIG. 21, a pasting position diagram 62 is provided inside the cover 61 of the case 6, thereby displaying the pasting position. As an explanation of the position of the LI15 point on the large intestine meridian, for example, when the elbow is bent, place the little finger at the tip of the wrinkle formed, align four fingers in width, and the place where the index finger touches is the LI15 point. Therefore, an explanation such as pasting so that this point comes to the center of the electrode pad 3 may be further added.

[0151] The user can correctly attach the beauty device 1 to the position of the LI15 point even without knowing the position of the LI15 point by referring to the case in which the position of the LI15 point on the large intestine meridian is shown and attaching the beauty device 1 along the display of the case. Therefore, even without professional knowledge or technology, the user can drive the beauty device 1 correctly attached to the position of the LI15 point to stimulate the LI15 point and the lung meridian, and remotely give an effect to the face through the meridians.

[0152] In FIG. 21, an example of displaying the pasting position on the inner surface of the cover 61 of the case 6 is shown. However, the pasting position may be displayed not only on the inner surface of the cover 61 but also on the inner side of the lower accommodating portion of the case 6.

[0153] Alternatively, the pasting position may be shown on the surface of the main body portion 2 of the beauty device 1, or the electrode pads 3 and 4. Further, the pasting position may be printed on an instruction manual or the like accommodated in the case 6.

[0154] (Usage procedure of the beauty device) FIG. 22 is a diagram showing the usage procedure of the beauty device 1 of the present invention.

[0155] In step S1, as shown in FIG. 22(a), the user attaches the electrode pads 3 and 4 of the beauty device 1 to the LI15 point on the arm and the lung meridian while referring to the case 6.

[0156] In step S2, as shown in FIG. 22(b), the user presses the operation button 26 to start driving.

[0157] In step S3, application of a current having a pulse group with the set conditions is continued.

[0158] After 10 minutes have elapsed, the application of current is automatically stopped in step S4.

[0159] In step S5, as shown in FIG. 22(c), the user removes the electrode pad from the cosmetic device.

[0160] In this way, with the beauty device 1 of the present invention, the user can effectively stimulate the five limbs of the hand even if he or she does not have specialized knowledge or skills.

[0161] In this flow, an example is shown in which the electrode pads 3, 4 are attached directly to the palmar and lung meridians of the upper arm, but it is also possible to improve the current transmission performance by, for example, applying a gel with specific electrical properties before attachment and then attaching the electrode pads 3, 4 to the applied position.

[0162] In the above flow, an example is shown in which the beauty device of the present invention is attached by the user, but the beauty device of the present invention may also be attached in the correct position by a practitioner during slimming or beauty treatment, etc.

[0163] (Flow when current is applied) FIG. 23 is a flow chart for applying a current having a group of pulses.

[0164] This flow is a detailed flow of step S3 in FIG.

[0165] In step S31, as the first energization, a group of positive pulse currents is applied for two seconds.

[0166] In step S32, no current is applied for one second, which is defined as a first pause period.

[0167] In step S33, as the second energization, a group of negative pulse currents is applied for 2 seconds.

[0168] In step S34, no current is applied for 1 second. This time is set as the second pause period.

[0169] Steps S31 to S34 are repeated until a predetermined number of times is reached in step S35. The predetermined number of times in step S35 is a number corresponding to the actual driving time. For example, when the driving time is set to 10 minutes, since the total time required for steps S31 to S34 is 6 seconds, the predetermined number of times in step S35 is set to 100 times.

[0170] Note that the times set as the energization period and the pause period do not have to be exactly 2 seconds and 1 second. As long as the energization period is longer than the pause period, it is possible to set the energization for 1 to 4 seconds and the pause for 0.5 to 2 seconds with a certain range. Therefore, according to the times set for this energization period and pause period and the driving time of the entire device, the predetermined number of repetitions is appropriately set. This predetermined number of times may be preset at the manufacturing stage, or may be configured such that a plurality of patterns can be selected by the user within the device.

[0171] When the predetermined number of times is reached in step S35, it automatically stops.

[0172] In this way, by physically stimulating the acupoints and meridians with a current having a predetermined pulse group, it is possible to stimulate from a remote site and improve the poor blood circulation state of the facial skin. As a result, there is no adverse effect by applying current within a predetermined range, and an effect can be obtained remotely on the face.

[0173] Note that in the above, an example of applying in one type of mode is described, but the beauty device of the present invention may be configured to be able to set two or more modes.

[0174] In that case, it has a storage unit that stores a plurality of current application patterns to the electrode pads. Then, by selecting the application pattern, the driving period of repeating energization and stop, and / or the amplitude of each pulse constituting the pulse group are appropriately set.

[0175] Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments described above, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims.

[0176] This application claims priority based on Japanese Patent Application No. 2020-035330 filed on March 2, 2020, the entire contents of which are incorporated herein by reference.
