Description

Apparatus for controlling blood pressure by searching spots on the body suitable for acupuncture}

The present invention relates to acupuncture-type blood pressure drop, and more particularly, to acupuncture-type blood pressure drop to perform abnormal biopotential discharge, low frequency stimulation, and menstrual blood detection function according to biopotential charge / discharge.

Human skin has an important function of purifying body fluids through breathing, secretion and excretion, the total area of which is about 1.6㎡ in adults, the thickness of the epidermis is about 1.5-2mm to protect the human body. In addition, the skin, also known as the mirror of the intestines, flows from the viscera of the five intestines to the surface of the skin innumerable meridians, and always carries the internal wastes and abnormal blood to the surface of the skin to act naturally. . Visceral abnormalities respond to the skin, and inevitably appear on the related meridians. Meridian skin is almost exclusively acne, warts, boils and spots. Therefore, in oriental medicine, a method of stimulating the acupuncture points of the human body to promote metabolism of the human body or to stimulate the human body for treatment purposes, by applying electricity to one end of acupuncture, cupping, moxibustion, or low frequency or electric stimulation such as low frequency. A number of methods for giving treatment are utilized by folk remedies or academic systems, and in particular, techniques for treatment by applying electrical stimulation to the human body are registered in Korean Patent Registration No. 10-197550 (February 24, 1999, application number) 10-1996-6387), "physiotherapy apparatus for therapeutic purposes," such as "electric stimulation apparatus and method for restoring exercise function," and the like have been put to practical use.

In general, the treatment of hypertension, there are a combination of oriental and herbal treatments, most of the characteristics of hypertension should be subjected to long-term or lifetime coercive therapy. Herbal treatment includes diet and meal therapy, and treatments that prescribe various medicines depending on the symptoms. On the other hand, in the case of bilateral treatment can be divided into drug therapy and non-drug therapy, the long-term use of the drug by the drug therapy causes many side effects as well as the various contraindications and other diseases accompanying the use of the drug (exists) And costly problems. In particular, hypertension needs to be treated for a long time, so countermeasures for such problems are emerging as a problem to be solved in the future medicine.

Accordingly, in recent years, the drug and non-drug therapies of such explosives are treated in parallel, and the non-drug therapies are mainly natural and dietary and herbal. The diet is mainly used as a preventive measure before complications for hypertension. In addition, herbal therapy is a therapy mainly used for one or more hypertensive patients based on the theory of meridian theory, and in such herbal therapy, blood pressure is lowered through pressure and stimulation caused by meridian acupuncture. This theory was published on June 92, 1994, by Taewoong Publishing Co., Ltd., on page 88 of the plain Silla ear acupuncture (written by Choi Kuk-jin). Pressure of hypertension patients is lowered when pressure stimulation is applied for 4 ~ 5 minutes. ”Also, acupuncture points of Hyundai Acupuncture Institute (published April 25, 1992) Lee Byung-guk) On the 79 pages of the visceral responsive site, it describes that each part of the ear is connected to each organ of the human body, and published on January 20, 1994 Acupuncture is defined as acupuncture points on a certain part of the human body, and it is called acupuncture points. On page 13 of the Meridian Orthodontic Health Act (published by Kim Yun-seok) published by Literary Landscape Publishing Company on July 15, “Meridian is distributed throughout the body, which is an important pathway for the movement of the body's blood and blood. It is the length of the circulatory system that connects with each other. ” And on page 1382 of Acupuncture (Seong Yong-tae, et al.) Published September 10, 1994, acupuncture points suitable for treating hypertension are described.

There are many theories that treat diseases by pressure and stimulation by acupuncture, etc. There are many practical theories. In particular, attempts are made to treat diseases such as hypertension by applying electrical stimulation to acupuncture points instead of acupuncture. In Sinan Publication No. 94-22053, a blood pressure is lowered using a charge / discharge vibration circuit controlled by a push button that receives a human body's bioelectricity through a clip and a wire set connecting an ear and an earphone jack on a cylindrical case of a regulator. Blood pressure regulators are characterized by raising.

On the other hand, low-frequency treatment by electric stimulation is the whole body of very weak electricity, so-called nerve current, such as electrocardiogram generated from the human body, for example, electrocardiogram generated from the heart, brain wave generated from the brain, and operating electric power generated from nerves or muscles. Use the principle to improve the state of the body by flowing to. Using this principle, it is known to have an action effect such as regulation of muscles, internal organs and nerves, blood circulation and metabolism. Everyone has an electrocardiogram from the heart, an EEG from the brain, and a working electricity from nerves and muscles. In other words, the neural current flows through the whole body to adjust the condition, to regulate the muscles and internal organs, nerves, and promote blood circulation metabolism. By the way, modern people have an abnormal nerve current in the human body due to heavy work, lack of exercise, and repetitive routines, and thus, arthritis, neuralgia and adult diseases are frequently occurring. In general, low frequency therapies are applied to the body by applying low-frequency currents similar to the nerve currents flowing through the body to apply electrical stimulation, thereby restoring abnormal nerve currents, causing contraction of paralyzed muscles, improving blood circulation, relaxing exercise, or soothing excited nerves. And removes pain. In addition, by stimulating the autonomic nerves of the human body to release fatigue and actively promote the secretion of hormones and enzymes. The low frequency oscillator used in this low frequency therapy generates a frequency of several hundreds to hundreds of Hz, and is used for preventing pulmonary soluble atrophy of paralysis muscle, analgesic and blood circulation improvement by electric stimulation.

Accordingly, the present inventors reduce the abnormal biopotential using the method by charging and discharging the abnormal biopotential of the human body, and at the same time, by applying low-frequency electric stimulation to the ear of the human body to obtain an acupuncture effect, thereby lowering the blood pressure to lower the blood pressure. Has been devised (Utility Model Registration No. 276503). In addition, the present invention has been proposed to reduce blood pressure more effectively by adding the function of detecting the menstrual blood.

Accordingly, an object of the present invention is to detect the acupoints of the body to perform abnormal biopotential discharge, low frequency stimulation, and menstrual blood detection function according to the biopotential charging and discharging. In accordance with the release of the abnormal biopotential to improve blood circulation and promote metabolism to provide a blood pressure detection type blood pressure lowering.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

First, the menstrual blood pressure detecting blood pressure drop of the present invention will be briefly described.

The present invention is a combination of a blood pressure drop function by a charge and discharge therapy and a needle acupuncture method to perform blood pressure control at the same time as a blood pressure detection by acupuncture points and a low blood stimulator using a two-channel pad It is about strength in blood pressure. In other words, the present invention performs an electronic blood pressure drop function to charge and discharge the biopotential detected in a particular menstrual blood from a high potential to a normal potential through a discharge circuit, and a low frequency stimulus using an acupuncture method is added thereto, and tapping is performed. It is a low frequency stimulus function that is programmed with functions, kneading function, acupressure function, and automatic repetition function of these functions.

Although not shown in appearance, buttons are provided on the outside to support a user's operation to select a mode, and among these buttons, a power switch is included. On the other hand, there is a built-in circuit board is formed a circuit configured to generate a pulse for performing the blood pressure drop and low frequency stimulation of the present invention.

1 is a circuit diagram of the menstrual blood pressure detecting blood pressure drop according to the present invention. 1, first, the menstrual blood pressure detecting blood pressure drop of the present invention is largely a charge / discharge circuit (A), a power supply circuit (B), a boosting circuit (C), a frequency generating circuit (D), a microcomputer circuit (E), It consists of an LCD circuit F, a buzzer circuit G, and a menstrual blood detection circuit H. The configuration of these component circuits will be described in detail.

First, the charge / discharge circuit A is connected to pin 20 of the microcomputer circuit E, and is turned on / off by a charge / discharge signal of a low level signal for 32 seconds and a high level signal for 2 seconds at a 34 second period. The transistor AQ1 and the capacitor AC1 are charged and discharged according to the turn-on / turn-off. The charge / discharge circuit A receives a low level signal from the transistor AQ1 for 32 seconds to turn the transistor AQ1 off to maintain a stop state, and to maintain a high level for 2 seconds. ), The transistor AQ1 is turned on to maintain an operating state. That is, when the transistor AQ1 is in the stopped state, the biopotential is charged for more than 32 seconds in the capacitor AC1, and the accumulated biopotential for 2 seconds is discharged through the transistor AQ1 in the operating state. Reference numerals AR1 and AR2 denote resistors connected to the transistor AQ1 collector and the base, respectively.

The power supply circuit B includes a battery Bat in which two LR03 1.5Vs are connected in series, a smoothing capacitor BC1 for stabilizing a DC power supplied from the battery Bat, a resistor BR1 and a capacitor. It consists of a reset part B1 which consists of BC2 and supplies a reset power supply to the microcomputer circuit E. FIG. The stable DC power supply through the capacitor BC1 is input to the 9th pin VDD of the microcomputer circuit E. In addition, the threshold signal is input through pin 16 (Reset).

The booster circuit C uses a booster circuit of a data sheet of UTCMC34063, and receives a 3V DC power supplied from a battery Bat to perform a DC / DC converter function. It boosts the power to 150V. And it is connected to the frequency generating circuit (D) to supply the made voltage. CRX represents a resistor, CCX represents a capacitor, CDX represents a diode, CQX represents a transistor, and CLX represents a coil. Where X is a variable.

The frequency generating circuit (D) is amplified by a low frequency signal in the range of 5V to 6V by the UTCMC34063 and the transistors (DQ1, DQ2, DQ3, and DQ4) of the boosting circuit (C) to which the 3V is input and output to the connector (PH1). do. That is, the frequency generating circuit (D) performs a switching action by using four transistors that are frequently used in the treatment device of the low frequency stimulator system to switch the large voltage (150V). That is, an unstable multivibrator is used. This unstable multivibrator is a simple passive circuit in which frequency oscillation is performed by the pulse signal of the microcomputer circuit E instead of the oscillation by RC time constant. Periodic pulse signals are input to the transistors DQ5 and DQ6 from pins 22 and 23 of the microcomputer circuit E, respectively, and turns on the transistors DQ1, DQ2, DQ3, and DQ4. For example, when a digital signal is first output from pin 22 of the microcomputer circuit E, the digital signal is applied to the base of the transistor DQ5 through the resistor DR7 and turned on. That is, since the base current Ib flows and the transistor DQ5 becomes a saturation region (a region in which the collector current does not increase even when the base current is increased), the transistor DQ5 performs an on operation of a switching operation, that is, a drive role. The same applies to the transistor DQ6 operated by the digital signal of pin 23.

At this time, when the H.V power is supplied, any one of the transistors DQ5 or DQ6 is operated and the other operation is stopped. Among the two transistors DQ5 and DQ6, the transistor having the lower voltage of the collector is operated first. For example, when a pulse signal is output to the transistor DQ5 connected to pin 22, the base current Ib of the transistor DQ3 flows and the emitter voltage of the transistor DQ3 operates the transistor DQ2. At this time, a square wave signal is generated between the emitter of the transistor DQ3 and the collector of the transistor DQ2. In addition, since the signal 23 has no pulse signal, the transistor DQ6 performs a switching off operation because the base current Ib of the transistor DQ6 is less than 0.6V. Therefore, the transistor DQ4 also does not operate, and thus the square wave signal is not output. The same applies to the case where a pulse signal is output to pin 23 and a pulse signal is not output to pin 22.

The microcomputer circuit E receives a signal to each of the circuits or outputs a control signal to perform the entire control of the menstrual blood pressure detecting blood pressure drop. Specifically, the driving is performed by receiving the power from the power supply circuit (B), the 32KHz driving supplied from the oscillating circuit to be described later is performed, and the switching of the corresponding mode input from the button (not shown) for mode selection is performed. To control the display, output the image control signal for driving the LCD, output the buzzer signal according to the remaining time counting and the button input to the buzzer circuit (G), and generate the low frequency generation signal of the high level or the low level at a predetermined predetermined period. It outputs a high-level or low-level charging and discharging signal at a predetermined time period, and receives and displays a battery voltage detection signal that monitors the remaining battery Bat. In addition, the determination of the menstrual blood points is made, and control to display the menstrual blood detection results on the LCD. Then, time counting is performed by itself so that switching control by the corresponding program can be performed to adjust the period of the low frequency generation signal and the charge / discharge signal.

The LCD circuit F uses a conventional matrix liquid crystal display panel using liquid crystals that are switched by driving voltages of the segment electrodes on the X-axis and the common electrode on the Y-axis so that display by mode is achieved. Micom Circuit (E) Detects the power supply voltage and displays the remaining amount of power, and receives the switching "on" signal to display five operations: tapping, kneading, acupressure, AUTO, and blood pressure drop. It is controlled by, and displays the signal in 15 minutes, followed by 15, 14, 13, ..., 9, 8, 7, ..., 1, 0. In addition, the operation status signal is displayed in each form.

The buzzer circuit G includes a transistor GQ1 turned on by the buzzer signal output from the microcomputer circuit E and a buzzer BZ connected to the emitter of the transistor GQ1. The buzzer BZ sounds a buzzer when a button (not shown) for mode selection is turned on, or a buzzer sounds periodically when the operation time of the blood pressure drop is 30 seconds before. The buzzer signal is output through pin 24 of the microcomputer circuit E. In addition, the buzzer sound is output when the acupoints are detected.

In addition, the microcomputer circuit E is provided with an oscillation circuit composed of the first capacitor C1, the second capacitor C2, and the crystal oscillator Y1 to supply an oscillation frequency. In this embodiment, 32 KHz is used for driving.

Figure 2 is a view showing the whole menstrual blood detection circuit used in the menstrual blood pressure detecting blood pressure drop of the present invention. As shown in Figure 2, the menstrual blood detection circuit (H) according to an embodiment of the present invention, the constant voltage generator (I), stimulus generator (J), amplification unit (K), acupuncture points frequency detection unit ( L). More specifically, the 1.3 [V] constant voltage generator (I), the stimulus generator (J) for applying AC power to the human body, the current voltage converter and amplifier (K) for measuring the magnitude of the applied current and , The acupoint detection frequency generating unit (L) for generating a frequency. Then, the acupuncture detection circuit (H) is connected to the LCD circuit (F) and the buzzer circuit (G), respectively, so as to perform a sound generation and display function to mask the presence or absence of acupuncture. Vin is a 3V power supply as an operating power supply of the menstrual blood detection circuit (H), VCC is a 3V power supply as an amplifier (Op-amp) operating power supply of the amplification part, and VEE is also the same as VCC, and the output voltage of the amplifier (Op-amp) Becomes VEE-VCC. That is, it becomes -1.5-3V. Vout is an output voltage of the amplification part, and the output voltage is compared to pin 31 of the microcomputer circuit. Hereinafter, each component will be described in detail with reference to FIGS. 3 to 8.

3 is a circuit diagram of a constant voltage generator. The constant voltage generation unit (I) generates a voltage equal to or less than the hydrogen ionization voltage of 1.36 [V] by making the current flowing into the human body constant and serves to prevent variation of the detection current through the human body.

The constant voltage generator I is designed using an LM317 regulator, as shown in FIG. 3. The LM317 can be operated with an output voltage that is adjusted over an output voltage range of 1.2 [V] to 37 [V]. And variable resistance You can adjust the output voltage by setting to any desired value. The voltage output through the LM317 can be calculated as follows.

ㆍ ······ [Equation 1]

Here, the chip (IC) Wow Typical values of are 1.25 [V] and 100 [kV], respectively.

4 is a circuit diagram of a constant voltage generator applied to the present invention. The circuit applied to the actual menstrual blood detection system adjusts the variable resistance (IR3) and checks it with DMM while setting the voltage to 1.3 [V] lower than the hydrogen ionization voltage, and it can be adjusted because pain can be felt depending on the skin condition of the subject. To make it work. In addition, the capacitors IC1 and IC2 are coupled to the output terminal of the LM317 to output the filtered voltage.

5 is a circuit diagram of a stimulus generator of the menstrual blood detection circuit. As shown in FIG. 5, the stimulus generator J serves to apply stimulation to the skin by converting a constant DC power received from the constant voltage generator I into an AC power source. QBS (Quad Bilateral Switch), which is an analog switch, is used. The user detects acupuncture points by holding one of the two electrodes PE1 and PE2 with his hand (ground) and touching the other to a position considered to be acupuncture points. Each of the two analog switches is controlled by a control signal transmitted from the frequency generator L connected to the magnetic pole generator J. FIG. First, when one control signal comes in, the upper left analog switch JS1 and the lower left analog switch JS2 operate. When another control signal is input, the upper right analog switch JS3 and the lower right analog switch JS4 operate. That is, since the poles of the two electrodes PE1 and PE2 are continuously switched by the alternating control signals, the human body is subjected to the stimulation of AC, not DC.

6 is an output waveform to an AC power supply stimulus generating unit. FIG. 6 shows a waveform obtained by converting the DC voltage received from the circuit for generating the SPAC stimulus and the constant voltage generator I into AC. Referring to FIG. 6, the stimulation method is a method of converting and applying an alternating current from a single power supply, and withdrawing current by the amount of current applied to the human body to suppress cell polarization and recover before cell polarization occurs. By reducing the impact of human body and improving the reproducibility. The AC power stimulation method receives a DC voltage of 1.3 [V] lower than the hydrogen ionization voltage to the constant voltage generator (I) using two channel control signals, and transmits a single power supply bidirectionally by analog switches (JS1, JS2, JS3, JS4). The blood level is identified by converting it into an AC waveform of ± 1.3 [V].

7 is a circuit diagram of the amplification unit of the menstrual blood detection circuit. Specifically, it is a circuit diagram of a non-inverting instrumentation amplifier. The amplifier K converts a current for measuring the magnitude of the applied current into a voltage and amplifies the micro voltage. The amplifier (Op-amp) used the LM324, and to measure the amount of current flowing into the human body as shown in Figure 7 is designed a measuring amplifier with the same in-phase removal ratio. In the instrumentation amplifier, the first amplifier KA1 and the second amplifier KA2 are non-inverting amplifiers having high input impedance and voltage gain. The third amplifier KA3 is a unit gain amplifier.

Is connected to the external, the first amplifier (KA1) is a differential input signal to the non-inverting input Take Amplify with the gain of. In addition, the first amplifier KA1 is equal to the second amplifier KA2. , Via input signal Also receives. To the inverting input of the first amplifier KA1. Is authorized It is amplified by the gain of. The in-phase signal voltage of the non-inverting input is amplified by the in-phase gain of the first amplifier KA1. Therefore, the total outputs of the first amplifier KA1 and the second amplifier KA2 are as follows.

[Formula 2]

[Formula 3]

Therefore, the differential input voltage of the third amplifier KA3 is as follows.

[Formula 4]

From here, In this case, the differential input of the third amplifier KA3 is as follows.

[Equation 5]

if, ego Since the third amplifier KA3 has unity gain, the final output of the amplifier is as follows.

[Equation 6]

[Formula 7]

Here, closed-loop gain and external resistance The value of can be calculated as The value of can be determined as 56 [㏀].

[Equation 8]

[Equation 9]

The measurement of the amount of current is suitable as a measuring amplifier by using a voltage drop proportional to the current supplied to the human body at both ends of a resistor installed for limiting the maximum current and short-circuit protection function between the AC power supply stimulus generating circuit and the constant voltage generator (I). After being converted to level, it is sent to the LCD circuit F and displayed.

8 is a circuit diagram of the acupoint detection frequency generator. As shown in FIG. 8, the menstrual blood detection frequency generator L is composed of an unstable multivibrator or a free running multivibrator circuit. This circuit generates a square wave signal between the collector and ground and generates two output signals to control the analog switch of the magnetic pole generating unit (J). To get a balanced output wave, LR1 = LR4, LR2 = LR3, LC1 = LC2, and LQ1 and LQ2 must be the same. This circuit is an RC oscillator circuit whose frequency is mainly controlled by an RC time constant consisting of a base resistor and a capacitor. The Vin voltage has a small effect on the output frequency but a big effect on the output amplitude.

When the Vin power is applied, either transistor LQ1 or LQ2 is turned on and the other stops. Of the two transistors, the lower collector voltage is operated first. Assuming LQ1 conducts before LQ2, LC1 discharges to LR3, LQ1 has no forward-biased base current, and the collector voltage is about Vin in a blocked state and LC2 is charged through the junction between the emitter and base of LQ1. LQ1 is saturated and the collector voltage of LQ1 is close to zero potential. When the discharge current of LC1 is consumed to LR3, the base current of LQ2 flows through LR3, causing LQ2 to saturate and LQ1 to shut off.

On the other hand, the microcomputer circuit E may generate two low frequencies by itself, and may input two terminals for outputting the generated low frequencies to JP1 and JP2 of the magnetic pole generating unit J, respectively. Accordingly, the menstrual blood detection frequency generator L generating low frequency may be omitted. This will simplify the circuit configuration and reduce the manufacturing cost.

Acupoint detection type blood pressure drop of the present invention configured as described above, by applying the acupuncture stimulation method and the optimal parameters to identify accurate acupuncture points and obtain information on the acupuncture points to provide useful information for diagnosis and treatment. AC power stimulation current applied to human skin is controlled by the acupoint detection frequency generator (L), generates two channels of 4.4 [kHz] square wave, and then connects two pairs of analog switches (JS1, JS2, JS3, JS4). The controller generates a single power supply alternating waveform, 1.3 [V], for the alternating power supply stimulation pattern.

The operation process of the menstrual blood pressure detecting blood pressure drop of the present invention configured as described above will be described in detail.

First, the configuration of the LCD window displaying the operation process will be outlined. As shown in FIG. 9, reference numeral 1 denotes a battery display unit, 2 an intensity display unit, 3 an hour display unit, 4 an tapping display unit, 5 a kneading display unit, 6 acupressure display unit, 7 an automatic repeat display unit, and 8 a blood pressure drop. Each display part is shown.

10a to 10c is a flowchart illustrating the operation of the menstrual blood pressure detecting blood pressure drop of the present invention. 1 to 10, when the user presses the power switch SW for a set time, for example, 2 seconds, the power is turned on (S1), and the power is supplied to the whole menstrual blood pressure detecting circuit. At the same time, initialization is performed in the microcomputer circuit E (S2). At this time, if the power switch SW is kept pressed for 2 seconds while the power is on, the power is turned off. In the initialization process, the recognition of each circuit is performed. For example, a series of processes including the capacity check of the battery Bat are performed. After the initialization is completed, the lighting is turned on in the tapping mode, which is the first mode, in a preset order, and the operation time is initialized and displayed for 15 minutes, and the intensity level is set to zero. Thereafter, when the user raises the intensity level, driving is performed as a ratio. When raising or lowering the intensity level, visually confirm the intensity display by raising or lowering it one by one. The above time may also be selected by the user. As described above, the first mode execution signal is output from the microcomputer circuit E, and driving is performed according to the programming process of the first mode set (S3 to S4).

At this time, it is determined whether an input for selecting another mode is made by the user while the first mode is being executed (S5). If another mode selection is made, the next mode will proceed in the order already set. On the other hand, if there is no mode conversion to adjust the intensity to perform the function. As described above, the intensity set by the user may be maintained or may be automatically changed and adjusted (S6). Thereafter, the user sets the time set by the user to determine whether 2 seconds before the end (S7), and if 2 seconds before the buzzer sound is generated (S8). After the set time, the power is automatically turned off to terminate the entire drive (S9).

On the other hand, if there is another mode selection in step S5 described above, the second mode execution signal set next is outputted, and the low-frequency stimulation kneading mode is driven by this execution signal (S10). The process of the kneading mode proceeds to the same user setting process as that of the first mode. On the other hand, if it is determined by the user that the input for the mode selection is continuously generated (S11), if it is determined that the mode selection is made continuously, the third mode, the fourth mode, the fifth mode, the acupressure mode that is the first mode, Automatic repetition mode, menstrual blood pressure detection and blood pressure drop mode, and tapping mode are performed, respectively, the process is continuously repeated (S12). Each mode described above performs the same processes from step S6 to step S9 described above.

Here, in the case of performing the fifth mode, which is one of the features of the present invention, the constant voltage generator I A constant voltage is generated at S120. At this time, the current flowing from the human body is continuously detected and read (S121). On the other hand, the stimulation generating unit (J) converts the constant DC voltage received from the constant voltage generating unit (I) to the AC power by the frequency generating unit (L) to apply stimulation to the skin (S122). The frequency generator (L) generates and applies an optimal frequency that can best detect current through the human body from the unstable multivibrator circuit, and provides four analog switches (JS1, JS2, JS3) of the stimulus generator (J). , JS4) will be controlled alternately. In the non-inverting instrumentation amplifier using three amplifiers KA1, KA2, and KA3, the amplification unit amplifies the microcurrent through the two electrodes JE1 and JE2. The voltage through the stimulus generating unit J is several mV. Since it is a small voltage, it is amplified to a voltage of several V which can be visualized through this circuit (S123). The microcurrent is detected (S124), and the amplified voltage is determined (S125). If it is determined that it is not a menstrual point, the above step S122 is continued. At the same time, the low frequency signal is outputted at the same time, the charging / discharging circuit is charged for 32 seconds at 34 seconds, and discharge is performed for 2 seconds (S126). Accordingly, electrical stimulation is applied to the human body while the forceps are left in the ear.
