Micro current stimulation device with magnetic pole patch {APPARATUS FOR MICRO CURRENT STIMULATION HAVING PATCH}

The present invention relates to a microcurrent stimulation device for smoothing the treatment, massage, etc. of the human body, and more particularly to a microcurrent stimulation device having a stimulation patch.

As is well known, a weak (microscopic) current flows through the human body, which is responsible for maintaining the health of the brain and organs by transmitting information to each other. In addition to indicating instability, microcurrents are known to have a function of actively supporting metabolism and blood circulation and eventually increasing natural healing. In other words, the appropriate microcurrent (about 0.06mA) is the weak alkaline of the blood, the expansion of blood vessels, the normalization of blood pressure, the diuretic action, the normalization of the pulse, the strengthening of the heart, the increase of collagen synthesis rate, the promotion of leukocytes, the bactericidal effect, the bacterial growth inhibition. It has been shown to be effective in inhibiting growth of E. coli, improving blood circulation of microvessels, promoting protein synthesis capacity, doubling treatment speed, promoting fatigue recovery, correcting autonomic nerves, promoting growth, purifying moisture, and removing odors. (Borgens et al .; Barker, Jasffe and Vanable, 1982; Borgens et al., 1980) (Korean Journal of Physical Therapy Vol. 16, No. 3) (Korean Journal of Professional Physical Therapy, Vol. 3, No. 1) Kwon No. 1) (Research Paper, Prof. Lee Tae-kyu, Kim Moon-chan, Department of Neurosurgery, Gangnam St. Mary's Hospital).

As another example, Kim, Jun Orthopedic Kwon, Won-An Kwon Department of Physiotherapy, College of Rehabilitation Science, Daegu University Park, Rae-Joon Department of Physiotherapy, College of Public Health, Taegu, Korea Department of Physiotherapy, College of Chonnam Science, Hwang, Tae-Yeon And animal experiments (Alvare, 1983; Bourguigron, 1987; Cheng, 1982; Suzuki, 1986) show that microcurrent stimulation activates tissue healing and repair processes. Evidence suggests that resynthesis, protein synthesis, and DNA replication rates are increased by direct electrical stimulation.

The effects of microcurrent stimulation have the effects of pain relief (pain reduction by directly blocking the propagation of action potential), edema reduction (reduction of edema due to the movement of body fluid), and the effect and metabolism of electric stimulation on muscle It is divided into changes in action and changes in blood vessels. In other words, the effect of microcurrent stimulation on the muscles, the muscles move by electrical stimulation through the nerve cells, stimulating the surface of the muscles with an electrotherapy device, when a certain amount of electricity enters, namely muscle atrophy It can delay the progression of the reduced state, and it has a motor effect by the repetitive action of contraction and relaxation, and the cooperative muscle is also activated.

As a metabolic change, experiments have demonstrated that the stimulated muscles can feel less fatigue such as reduced lactic acid and prevent oxidase activity due to changes in enzymes. As the distribution increases, peripheral blood vessels expand to help improve blood flow.

In recent years, the number of diabetics has increased rapidly, and it is known that about 10% of the total population suffers from diabetes. Diabetes is known to be caused by changes in diet, bad drinking culture, and lack of exercise caused by modern people's busy schedules.

In general, the appearance of diabetes initially causes problems throughout the body, but gradually causes nerves, blood vessels, and the immune system to break down, and nerves are gradually destroyed and blood vessels become clogged. For example, 15-20% of patients hospitalized with diabetes may show foot ulcers. Foot ulcers are a major obstacle in diabetics, ranging from 28% to amputation, which is astronomical.

Diabetic foot disease, which is caused by a combination of microvascular disorders, free radicals, and glycation of proteins due to prolonged hyperglycemia, includes abnormalities, necrosis, calluses, and refractory athlete's foot. If you have diabetes, your hand or foot will be easily injured, and if the infection is caused by a wound, unlike healthy people, it will not cure well and will spread to the upper part.If you miss the initial treatment period, the disease will progress rapidly and cannot be reversed. May result. In addition, as diabetes progresses, most patients have neuropathy, which is a symptom of abnormalities caused by sensory neuropathy at the lower extremities of the lower extremities, causing the hands or feet to become cold, tingling and burning. In addition, the sense of hand or foot is dull, the trauma easily appears, resulting in gangrene due to infection, etc. If not properly managed may cause serious problems such as cutting the lower limbs.

On the other hand, microcurrent stimulation has been reported in many studies for the healing of damaged tissues by flowing a microcurrent to the damaged tissues, such as pressure ulcers, congestive ulcers and diabetic ulcers. The most direct effect of microcurrent stimulation is to reduce the stimulation of the sympathetic nerve, which causes the contraction of muscles located in the vessel wall in peripheral blood vessels, thereby reducing blood flow, thereby increasing blood flow to the skin. In wound healing, various studies have shown that the effect of microcurrent has increased tissue oxygen saturation with increasing blood flow in diabetic ulcer sites. Misen current stimulation stimulates angiogenesis, increases the biosynthesis of fibroblasts and proteins, and the flow of current from the cathode to the anode increases the migration of fibroblasts and synthesized proteins in wound margins, preventing bacterial growth. It has an effect on wound healing with an increase in tissue oxygen saturation copper due to increased blood flow. The angiogenic stimulating effect of the microcurrent is caused by the increased production of VEGF by the current. According to Clover et al., A 6-week stimulation with a microcurrent that does not cause muscle shortening in patients with peripheral vascular disease demonstrated a 25% increase in capillaries compared to pre-stimulation on capillary microscopy.

Accordingly, in recent years, various types of microcurrent stimulation apparatuses that can implement various therapeutic effects or massage effects by stimulating microcurrents to the human body have been released.

However, the conventional microcurrent stimulation device has a problem that it does not control the level of the microcurrent actually supplied to the human body.

Human skin resistance varies from person to person. Therefore, even when the same level of microcurrent is supplied to the human body, since the skin resistance is different, the level of the microcurrent actually supplied to the human body is different for each person. That is, in the case of the human body having large skin resistance, the level of microcurrent flowing through the human body is lowered, and in the case of the human body having small skin resistance, the level of microcurrent flowing through the human body is increased. In the case where the level of the microcurrent having the highest therapeutic effect is determined, if the level of the microcurrent is higher or lower than this, a problem that the therapeutic effect is lowered occurs.

The present invention has been made in view of the above, and to provide a microcurrent stimulation device having a stimulation patch that can improve the treatment effect or massage effect by maintaining a constant level of the microcurrent actually supplied to the human body The purpose is.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 is a view showing a microcurrent stimulation device having a stimulation patch according to an embodiment of the present invention.

The microcurrent stimulation apparatus according to the present invention includes a microcurrent generator 100 and a magnetic pole patch 200 connected to the microcurrent generator 100 side.

The microcurrent generator 100 includes a case 151 having a compact size, and an on-off switch 151c is provided on an outer surface of the case 151. An opening is formed in an upper portion of the case 151, and a cover 152 is detachably coupled to the opening. A circuit board 153 is provided in the case 151, and a battery 154 is connected to the circuit board 153 side.

Clip 157 is provided on the outer surface of the case 151 as shown in FIG. It can also be installed.

Guide protrusions 152a are formed at both sides of the cover 152, and guide grooves 151a are formed at the opening side edges of the case 151. Accordingly, the guide protrusion 152a of the cover 152 slides on the guide groove 151a side of the case 151 to be easily coupled thereto, and an uneven portion 152b is formed on an upper surface of the cover 152. As a result, the cover 152 can be separated more easily through the uneven portion 152b.

The battery 154 is replaceably connected to the battery terminal 155 connected to the circuit board 153, as shown in FIG. 3. The battery terminal 155 has a structure bent in a "c" shaped structure, and the battery 154 may be easily inserted and detached therein.

The battery 154 may be generally used for all batteries known to those skilled in the art. That is, all batteries can be used, including primary batteries such as alkaline batteries and manganese batteries, and secondary batteries such as lithium-ion, nickel-hydrogen and nickel-cadmium batteries. As for battery power, 3V coin battery as well as 1.5V general battery can be arranged in series to supply 3 ~ 12V DC power.

In addition, a cushioning material 156 such as a sponge or the like is installed under the battery 154, whereby the circuit board 153 and the battery 154 may be safely protected even by an external impact.

At least one magnetic pole patch 200 has a gel adhesive layer 201 formed on one surface thereof, and a magnetic pole portion 202 made of a conductive material is provided at a central portion thereof. In particular, the magnetic pole portion 202 is more than the adhesive layer 201. It is preferably configured to protrude to be in direct contact with the human body. The magnetic pole part 202 may be configured as a flat surface having a predetermined area, or may be configured as a protrusion having a pointed tip to increase contact accuracy with a human body.

The microcurrent generator 100 is electrically connected to the magnetic pole part 202 so that the microcurrent generated by the microcurrent generator 150 is transmitted to the human body through the magnetic pole part 202.

By such a configuration, the magnetic pole patch 200 can be easily attached to various positions of the hand or the foot or other human body by the adhesive layer 201. As described above, the microcurrent generated by the microcurrent generator 150 is transferred to the human body through the stimulator 202 in the state where the stimulation patches 200 are attached to various positions of the human body, thereby preventing or treating the human body by the microcurrent stimulation. The effect can be enhanced.

It is known that a microcurrent of about 0.06 mA flows in the human body, and the strength of the microcurrent varies depending on the state of health. In general, a phenomenon in which the amount of microcurrent flows in a poor state of health is known clinically.

Thus, by stimulating the microcurrent from the outside having a size enough to stimulate the human body may contribute to the internal balance. In addition, although there is a slight difference depending on the sense level of the body, it is generally known that a current of about 1 mA can be sufficiently perceived, and a long time energization is known to be undesirable.

Therefore, if the size of the microcurrent is less than 1 μs to a few hundreds of amps, it may be suitable for the massage or treatment, and it may be desirable that the microcurrent flows intermittently for a certain period of time instead of continuous flow to give electric stimulation. .

According to the present invention, the microcurrent generated by the microcurrent generator 100 may be delivered to the acupuncture points or other parts of the sole, ankle, and instep of the human body through the stimulator 202 to perform electrical stimulation.

In addition, the stimulation unit 202 according to the present invention may be divided into a negative electrode plate and a positive electrode plate, and may further increase the effect of the electrical stimulation by separating the cathode current and the positive electrode current to the skin of the human body.

Meanwhile, the power generation circuit of the circuit board 153 includes a control unit 110, a boosting unit 120, and a microcurrent output unit 130 as shown in FIG. 6.

The control unit 110 may include a first control signal S1 for generating a microcurrent having a positive phase, a second control signal S2 for generating a microcurrent having a negative phase, and a booster for boosting a power supply voltage. The third control signal (S3) is generated to control the microcurrent generation. The control unit 110 checks the level of the microcurrent supplied to the human body through the microcurrent generator 100 and controls the third control signal S3 to change the voltage level of the boosted voltage when it is not a predetermined level. By controlling the human body supply level of the microcurrent.

The control unit 110 may include a control chip having a CPU to generate the first to third control signals S1, S2, and S3.

The booster 120 boosts the power supply voltages Vdd and Vcc to a boosted voltage of a predetermined level in response to the third control signal S3 of the control unit 110 and supplies the boosted voltage to the microcurrent output unit 130.

The booster circuit constituting the booster unit 120 includes a booster circuit of a DC-DC converter type using a back electromotive force of an inductor, a charge pump circuit using a capacitor, and is well known to those skilled in the art. Various known boost circuits can be used.

The microcurrent output unit 130 generates a microcurrent of a desired level based on the boosted voltage boosted by the booster 120 and supplies the microcurrent output unit 130 to a specific part of the human body through contact terminals contacting the human body. In this embodiment, the contact terminal corresponds to the magnetic pole part 202 of the magnetic pole patch 200.

The microcurrent output unit 130 supplies a microcurrent having a positive phase when the first control signal S1 is input, and a microcurrent having a negative phase when the second control signal S2 is input. Will be supplied.

Here, the microcurrent is a current level of 0 to 1000 mA (not including 0) and refers to the micro current in microamps. The microcurrent output unit 130 is generated by selecting any one current level that is determined to have the highest treatment effect or massage effect among current levels of 0 to 1000 mA (not including 0). For example, a microcurrent of 0 to 300 mA or a micro current of 100 to 150 mA can be output.

The microcurrent output unit 130 includes at least one voltage distribution circuit and a plurality of switching elements to generate a microcurrent, and each of the plurality of switching elements may include a first control signal S1 or a second control signal S2. In response to the switching operation.

The microcurrent can be varied in response to the skin resistance of the human body used to make the level of the microcurrent actually supplied to the human body constant.

To this end, the microcurrent output unit 130 generates a supply level confirmation signal for confirming the human body supply level of the microcurrent supplied to the human body and provides it to the control unit 110, and the control unit 110 supplies the supply level confirmation signal. In response to this, the level of the boosted voltage of the booster 120 is controlled.

Here, the supply level confirmation signal provides a function for confirming whether the condition for supplying the microcurrent is actually made in contact with the human body in addition to the function for confirming the level of the microcurrent actually supplied to the human body.

FIG. 7 is a circuit diagram illustrating the configuration of FIG. 6 in detail.

As shown in FIG. 7, the control unit 110a may determine whether a control chip (for example, PIC16F716) (U2), a resistor (R4), a capacitor (C4), a power source (Vcc), or a power supply is present. Including the LED (D2) has a wiring structure as shown in FIG. The control chip U2 may be a generator of a control signal having various kinds of frequencies.

As described with reference to FIG. 6, the control unit 110a may include a first control signal S1 for generating a microcurrent having a positive phase, a second control signal S2 for generating a microcurrent having a negative phase, and Generation of the third control signal S3 for boosting the power voltage controls the generation of the microcurrent.

In addition, the control unit 110a receives the supply level confirmation signal MC for confirming the human body supply level of the microcurrent supplied to the human body provided by the microcurrent output unit 130a to boost the voltage of the booster unit 120a. You can control the level of (VC). The level control of the boosted voltage VC is possible through the third control signal.

Although the control unit 110a checks the human body supply level of the microcurrent through the supply level confirmation signal MC, it is also possible to check whether the human body contact terminals P1 and P2 actually contact the human body. This is because it is possible to determine that the human body contact terminals P1 and P2 are in contact with the human body if the supply resistance signal MC is within a certain range corresponding to the skin resistance because the range of the human body's skin resistance is determined. In this embodiment, the contact terminals P1 and P2 correspond to the magnetic pole part 202 of the magnetic pole patch 200.

Therefore, when power is supplied, the control unit 110a first checks whether the human contact terminals P1 and P2 are in contact with the human body through the supply level confirmation signal MC, and determines whether to generate a microcurrent. Will be. That is, when it is confirmed that the human body is contacted through the supply level check signal MC, the microcurrent generator 100 performs the microcurrent generation, and thereafter, the function of confirming the actual human body supply level of the microcurrent is performed. .

Since the control unit 110a has to be movable and portable, the power supply voltage may be configured to be supplied through a battery.

The booster 120a includes a switching element Q7 in which switching is repeated by the third control signal S3 generated by the control unit 110a, an inductor L1, rectification and ripple prevention, and storage of the boost voltage. A diode D1, capacitors C1 and C2, and a resistor R10 have a wiring structure as shown in FIG. In this case, a transistor is used as the switching element Q7, but various switching elements including a MOSFET may be used.

As shown in FIG. 9, the booster 120a may be configured through a boost circuit of a DC-DC converter type having the boost stage 10 in multiple stages, and may be configured through various boost circuits such as a boosting circuit. It is possible to implement

The microcurrent output unit 130a includes a plurality of voltage dividers using a plurality of resistors R1, R6, R2, R7, R8, and R9 and a plurality of switching elements Q1, Q2, Q3, Q4, Q5, and Q6. The microcurrent is output to the human body contact terminals (P1, P2) by using. The plurality of switching elements Q1, Q2, Q3, Q4, Q5, and Q6 use transistors, but various switching elements including MOSFETs may be applied.

Some switching elements Q6 and Q3 of the switching elements Q1, Q2, Q3, Q4, Q5 and Q6 are controlled by the first control signal S1, and some switching elements Q5 and Q4 The second control signal S2 is controlled, and the remaining switching elements Q1 and Q2 have a structure controlled by the voltage of the first node n1, that is, the boosted voltage VC.

The human body contact terminals P1 and P2 are mounted on specific parts of the human body (sites requiring treatment or massage), and the second human contact terminals are provided with a microcurrent applied through the first human contact terminal P1 through the human body. It may be configured to return to (P2), or to allow the micro-current applied through the second human contact terminal (P2) to pass through the human body to return to the first human contact terminal (P1).

FIG. 8 is a timing diagram of the control signal and the fine current of FIG. 7.

Hereinafter, the operation of the microcurrent generator of FIG. 7 will be described with reference to FIG. 7 and through the timing diagram of FIG. 8.

First, the microcurrent generator 100 operates in a state in which the human body contact terminals P1 and P2 of the microcurrent output unit 130a of the microcurrent generator 100 are mounted on a specific part of the human body.

When power is supplied through the battery, the control unit 110a generates a signal for confirming whether or not the human body is in contact with the microcurrent output unit 130a or a third control signal S3 for generating a normal microcurrent. Receiving the level check signal (MC) to check whether the human contact terminals (P1, P2) actually contact the human body.

This is because when the level of the supply level confirmation signal MC is positioned within a predetermined range in consideration of the skin resistance of a general human body, it is possible to determine that the human body is in contact with the human body.

Thereafter, the control unit 110a supplies the third control signal S3 for generating a microcurrent to the boosting unit 120a. The third control signal S3 is a control signal whose width and period are adjusted for boosting.

When the third control signal S3 is applied, the switching element Q7 of the booster 120a is turned on / off in response to the third control signal S3.

When the switching element Q7 is turned on, the current of the inductor L1 starts to increase, and the diode D1 is turned off because the bias is applied in the reverse direction, and thus the inductor L1 voltage Is equal to the power supply voltages Vcc and Vdd.

When the switching element Q7 is turned off by the third control signal S3 again, the current of the inductor L1 starts to decrease, so that the voltage of the inductor L1 is changed in polarity. Combined with the supply voltage. This voltage is stored in capacitor C1.

In this case, a forward bias is applied to the diode D2, and the capacitor C2 stores a voltage output through the diode D2, and a pulsation (ripple) of the output voltage, that is, the boosted voltage VC, is applied to the diode D2. Remove it.

When the next switching operation is performed, a voltage corresponding to twice the voltage stored in the capacitor C1 is stored in the capacitor C2. When a plurality of switching operations are performed in this manner, the power supply voltage is applied to the first node n1. A boosted voltage VC is generated several times to several ten times higher than (Vcc, Vdd). For example, assuming that the power supply voltage is 3V, it is possible to obtain a voltage of 30V. Of course, it is also possible to generate higher levels of voltage.

That is, when the switching element Q7 repeatedly performs the on / off operation according to the width and the period of the third control signal S3 of the control unit 110a, the boosted voltage VC has a desired level.

When the boosted voltage VC reaches a desired level, the control unit 110a generates the first control signal S1 and the second control signal S2. The first control signal S1 and the second control signal S2 may be generated at the same time as the supply of the power supply voltage of the control unit 110a. However, since the boosted voltage VC does not reach a desired level, it is not necessary here. It is assumed that it occurs when the boosted voltage VC reaches a desired level.

The first control signal S1 is for generating a microcurrent having a positive phase, and the second control signal S2 is for generating a microcurrent having a negative phase.

When a microcurrent having a positive phase and a negative phase is generated and supplied to the human body, the treatment and massage effects are known to be superior to those of the microcurrent having only a positive phase.

The first control signal S1 is shown in FIG. 8. It may have a waveform structure of the pulse (pulse) having a certain period and a certain duty ratio (duty ratio). For example, it may have a waveform structure having a period of 1 second and a constant voltage level for a time of 150 ms, and a voltage level of 0 for the remaining time.

However, this is just one example. In consideration of the effective aspects of treatment or massage, the period or duty ratio may be changed by a unit of time, and the period or duty ratio may have a different waveform structure.

The second control signal S2 may have a waveform structure in the form of a pulse having a certain period and a constant duty ratio in a form having a predetermined phase difference from the first control signal S1. The second control signal S2 has the same shape except that it has a predetermined phase difference from the first control signal S1.

Here, the second control signal S2 should have a voltage level of 0 in the time interval t1 in which the first control signal S1 has a constant voltage level, and the first control signal S1 has a voltage level of 0. In some sections of the time section T-t1, the waveform structure has a constant voltage level.

That is, the pulse of the first control signal S1 and the pulse of the second control signal S2 are generated so as not to overlap. In detail, a time point at which the switching elements Q6 and Q3 are turned on by the first control signal S1 and a time point at which the switching elements Q5 and Q4 are turned on by the second control signal S2 should be different. It is also possible to cause the switching devices Q5 and Q4 to be turned on by the second control signal S2 immediately after the switching devices Q6 and Q3 are turned on by the first control signal S1 and turned off again. The switching elements Q6 and Q3 are turned on by the first control signal S1 and then turned off again, and the switching elements Q5 and Q4 are turned on by the second control signal S2 after a predetermined time. It is also possible. This is possible by controlling the timing of the pulse generation of the second control signal S2, and may be determined differently as necessary in consideration of the treatment or massage effect.

When the boosted voltage VC reaches a predetermined level, the microcurrent output unit 130a turns on the switching element Q1 by the voltage divided by the voltage distribution of the resistors R1 and R6, and the resistor R2. The voltage divided by the voltage distribution of R7 turns on the switching element Q2. This is possible when the switching elements Q5 and Q6 are turned off. When the switching element Q6 is turned on by the first control signal S1 even when the boost voltage VC reaches a predetermined level. When the switching device Q2 is turned on and the switching device Q1 is turned off and the switching device Q5 is turned on by the second control signal S2, the switching device Q1 is turned on and switched. Element Q2 is turned off.

When the first control signal S1 and the second control signal S2 are applied to supply the microcurrent, the microcurrent supply is started.

When the switching elements Q6 and Q3 are turned on by the first control signal S1 and the switching elements Q5 and Q4 are turned off by the second control signal S2, the switching element Q2 is turned on. On, the microcurrent is supplied to the human body through the switching element Q2 and the human body contact terminal P1 at the first node n1, and the microcurrent supplied to the human body is the human body contact terminal P2 and the switching element Q3. ), And are recovered through the resistors R8 and R9. At this time, the switching elements Q5, Q4, and Q1 are turned off by the second control signal S2. At this time, the microcurrent supplied to the human body has a positive phase, as shown in the microcurrent graph P1-P2 of the human body contact terminal of FIG. 8.

Thereafter, when the switching elements Q6 and Q3 are turned off by the first control signal S1 and the switching elements Q5 and Q4 are turned on by the second control signal S2, the switching element Q1 is turned on. On, the microcurrent is supplied to the human body through the switching element Q1 and the human body contact terminal P2 at the first node, and the microcurrent supplied to the human body is the human body contact terminal P1 and the switching element Q4 and the resistor. It is recovered through (R8, R9). At this time, the switching elements Q6, Q3, and Q2 are turned off by the first control signal S2. At this time, the microcurrent supplied to the human body has a negative phase, as shown in the microcurrent graph P1-P2 of the human body contact terminal of FIG. 8.

As already described, the level of microcurrent supplied to the human body is different for each human body because the skin resistance is different for each human body. Therefore, in order to increase the effect of massage or treatment, a microcurrent within a certain level range must be supplied, thereby raising the necessity of checking the level of the microcurrent actually supplied to the human body.

Therefore, the microcurrent output unit 130a has a configuration capable of controlling the level of the microcurrent supplied to the human body by checking the level of the microcurrent recovered through the human body contact terminals P1.P2.

The microcurrent flowing through the resistors R8 and R9 or a voltage corresponding to the microcurrent can be used as a supply level confirmation signal MC for confirming the human body supply level of the microcurrent supplied to the human body.

The supply level confirmation signal MC may send a microcurrent flowing through the resistors R8 and R9 to the control unit 110a. As shown in FIG. 7, the supply level confirmation signal MC is distributed through the voltage distribution of the resistors R8 and R9. It is also possible to use the voltage level as the supply level confirmation signal MC.

The supply level confirmation signal MC is provided to the control chip U2 of the control unit 110a, and when the supply level confirmation signal MC is provided in the control unit 110a, the supply level confirmation signal MC is analyzed and finely supplied to the human body. Confirm that the current level is at the desired level.

If the level of the microcurrent actually supplied to the human body is within the desired level range, no separate operation is performed. However, if the level of the microcurrent is out of the desired level range, the boosted voltage of the boosting unit 120a is increased through the third control signal S3. VC) to control the level.

When the level of the boosted voltage VC is controlled, the level of the microcurrent actually supplied to the human body through the human body contact terminals P1 and P2 is changed, and the control through the control unit 110a is actually supplied to the human body. The level of microcurrent continues until the desired level range is reached.

As described above, by the microcurrent generator of the present invention, it is possible to cross-generate a microcurrent having a positive phase and a negative phase, and to control the microcurrent actually supplied to the human body to be within a desired level range. By doing so, there is an effect that can increase the massage effect and treatment effect.

The foregoing description of the embodiments is merely illustrative of the present invention with reference to the drawings for a more thorough understanding of the present invention, and thus should not be construed as limiting the present invention. It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the basic principles of the present invention.
