Acne improvement device using electrical stimulation {ACNE IMPROVEMENT DEVICE USING ELECTRIC STIMULATION}

The present invention is for alleviating inflammation in acne, and more specifically, relates to an acne improvement device using electrical stimulation that can improve inflammation in acne by stimulating acne treatments applied to the skin with a micro-current to increase skin penetration. will be.

Acne, which is mainly distributed on the face, has a significant impact on the appearance of modern people who value social activities and interpersonal relationships, so early and consistent treatment is required even if it is a relatively mild symptom.

As a cause of acne, pigmentation can last for more than a year, and it causes scars and erythema, leading to side effects such as decreased immunity and skin diseases.

Current acne management methods include drug treatment that suppresses the inflammatory response, injection therapy, physical and chemical peeling, exfoliation, and laser therapy to remove clogged hair follicles and promote sebum discharge, preventing the growth of bacteria that cause acne. There are ways to suppress inflammation, etc.

Chemically synthesized antibiotics are prescribed as acne treatments to suppress the action of acne bacteria, but they are problematic due to various side effects such as resistance.

Meanwhile, microcurrent refers to a weak current of less than about 1,000 microamps (㎂), which is a weak current similar to the weak biological current of about 40 to 60㎂ flowing in the human body. It is known that the human body's biological current plays a role in maintaining health by transmitting information between the cerebrum and organs and promotes metabolism and blood circulation, ultimately enhancing natural healing power.

Because microcurrent is within the body's own physiological current range, muscle contraction does not occur, it is sensuously comfortable, there is no electrical discomfort, excellent stability, and it has the advantage of having almost no side effects on the human body even when used for a long time.

Previous studies using microcurrent have presented evidence through clinical experiments on the various effects of microcurrent that microcurrent stimulation activates tissue healing and recovery processes and increases intracellular ATP resynthesis, protein synthesis, and DNA replication rates. there is.

In this way, microcurrent stimulation can be used to increase skin penetration, resulting in maximized effects in acne treatment.

As a prior art device for relieving acne inflammation, Patent No. 10-1445005 relates to a metal patch kit, and more specifically, it uses nanocurrents generated by the difference in electronegativity between two metals to produce proteins related to inflammatory reactions. It is disclosed that a patch kit for treating infectious and non-infectious inflammatory diseases has the advantage of being safe as it effectively inhibits proteins related to inflammatory responses and does not show cytotoxicity in vivo.

However, the present invention proposes a use for alleviating or improving inflammation based on fewer side effects and activating tissue healing and recovery processes by using microcurrents of similar intensity to biological currents.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 is a main configuration diagram of an acne improvement device using electrical stimulation according to an embodiment of the present invention. As shown, the acne improvement device of the present invention improves skin penetration of cosmetics, nutrients, or therapeutic agents through microcurrent stimulation. It is a device that can improve the inflammation or treatment of acne by increasing the amount of acne.

Referring to the drawing, the acne improvement device 100 of the present invention has a control module 110 capable of setting the frequency and operation time, and is electrically connected to the control module 110 and attached to the skin to apply a micro current. It can be configured to include a pair of pads 120.

The control module 110 is configured to set the range, frequency, and operation time of the microcurrent.

For this purpose, the control module 110 is equipped with keys that can set microcurrent, frequency, and setting time through the key input unit 130.

Specifically, the key input unit 130 includes a key for setting the range of microcurrent from 10 to 100 ㎂ in 10 ㎂ increments, a key for setting the frequency in 10 Hz increments from 1 to 60 Hz, and a key for 10 minutes in the 1 to 2H range. It may be equipped with keys that can set the time in units.

In addition, the acne improvement device of the present invention can be provided with keys that can turn the power on and off, as well as keys that can repeatedly set the number of stimulations.

The display unit 140 is configured as a display that displays the setting process and operation process under the control of the control module 110.

The power supply unit 150 is a device for supplying power to the acne improvement device of the present invention and can be composed of a rechargeable battery or an adapter that directly receives alternating current power and supplies the necessary direct current power.

The pads 120 are provided in pairs and are attached to the left and right and/or above and below the lesion to be treated.

For this purpose, the pad 120 is made in the form of a patch or tape coated with adhesive conductive hydrogel, and the hydrogel has an adhesive component, so the pad 120 is used by attaching the corresponding side to the skin.

also, Of course, the pad 120 can be a regular patch that can be attached to the skin.

When power is applied, the control module 110 operates to apply a stimulation signal to the pad 120 through the key input unit 130 according to the intensity and frequency of the current set according to the size and symptoms of the lesion and the operation time.

For this purpose, the current generator 114 operates to apply the relevant micro-current to the pad 120 according to the set micro-current data transmitted from the control module 110, and the related frequency is applied to the pad 120 according to the data of the set frequency. It is provided with a frequency generator 112 that operates to be applied to.

The current generator 114 operates to output the power applied from the power supply unit 150 to the pad 120 in the form of a fine constant current waveform according to the fine current setting data transmitted from the control module 110.

That is, the pad 120 operates to apply stimulation to the skin area to be stimulated by the waveform of the fine constant current applied from the current generator 114.

The micro-current setting data is configured to be set in 10 ㎂ increments in the range of 10 to 100 ㎂, corresponding to biological micro-current, through the key input unit 130.

The frequency generator 112 is a device that generates low frequencies to provide electrical stimulation to the user's body parts. It responds to a control signal from the control module 110 so that the pad 120 stimulates the skin at a frequency set through the key input unit. It is driven by

The control module 110 controls the frequency generator 112 according to the frequency input through the key input unit 130, and the frequency generator 112 controls body parts according to the frequency data transmitted by the control module 110. Generates a low-frequency waveform suitable for

These frequency settings are configured to be set in 10Hz increments in the range of 1~60Hz.

Meanwhile, the control module 110 stores the operation time, current, frequency, or number of repetitions for each body part for each user (hereinafter referred to as user-specific setting data), and sends the user to the external terminal 200 through the communication unit 116. When managing by transmitting specific setting data or transmitting data set in the terminal 200, the control module 110 controls the current generator 114 and the frequency generator 112 based on the received data to set the The pad 120 is controlled to operate at a set frequency and current within a set time.

To this end, the communication unit 116 holds a unique ID for each device and allows data to be exchanged based on the unique ID when transmitting and receiving data with the external terminal 200, and the terminal 200 is equipped with the acne improvement device of the present invention. Provide an application to control or set, run the application, enter the unique ID of the device you want to control, set the setting data for each user and transmit it to the acne improvement device, and one or more acne that receives the signal If the unique ID in the received data is the same, the improvement device can control the pad based on the received setting data for each user.

Separately, the control module 110 stores setting data for each user by allowing the user to enter a unique ID (resident registration number, phone number, etc.). When the power is turned on, the control module 110 displays the information on the display unit 140. The unique identification name (e.g., name) corresponding to each user's unique ID is displayed so that the user can easily refer to it when reusing it in the future.

In addition, the control module 110 is configured so that the setting time can be set in 10-minute increments in the range of 1 to 2H through the key input unit, and the number of repetitions can also be set.

As described above, the present invention allows each user to control the pad with a set time, set frequency, and set intensity of microcurrent according to the body part.

In other words, stimulation is applied by setting the intensity, frequency, and operation time of the current according to the size and symptoms of the lesion.

The reason why the intensity of stimulation varies is because the skin impedance value is different for each person, so in order to deliver the target intensity, if the impedance is high, the intensity of the current may be increased, and if the impedance is low, the intensity of the current may be weakened. Therefore, our research team conducted an experiment by applying stimulation through a stimulation device made based on impedance feedback, and set the optimal conditions as follows.

The intensity of the current is a microcurrent stimulation condition that can actually produce an effect, and the range of the microcurrent is set in the range of 10 to 100㎂ in 10㎂ increments.

In particular, skin impedance, which is the resistance component of the skin, is a major cause of reducing the effectiveness of stimulation. This skin impedance varies from person to person, and even for the same user, it changes depending on the skin condition at the time of use, duration, etc., so the same stimulation is applied. However, because the effect may vary depending on the user, it is set in the range of 10 to 100㎂.

In addition, several scholars have revealed that a small current, that is, a small current in the ㎂ unit, is more effective in treatment than a high-intensity current.

In addition, because ATP production is inhibited when the current stimulation is more than 500 μA at the cell level, the maximum current stimulation is set to less than 100 μA.

Since this type of microcurrent stimulation is of a magnitude that the user cannot feel, the user's random selection method is not appropriate, so it is configured to be automatically adjusted within the stimulation device.

The frequency ranges from 1 to 60 Hz and can be set in 10 Hz increments, but it is preferable to use it fixed at 10 Hz.

The reason for specifying the frequency in this way is to transmit the electrical stimulation to the deep area (fat tissue).

Electrical conductivity and dielectric constant are obtained by changing the frequency of stimulation from 10 Hz to 20 GHz in human and animal tissues, and within this range, the International Commission of Non-Ionizing Radiation Protection (ICNIRP) in 2010 According to the guidelines presented in 2012, the frequency magnitude and exposure time were determined within the range where unpredictable adverse reactions to cells or tissues did not occur when applied.

Among these, 10Hz was selected, which is a frequency range that is safe to stimulate cells and has a specific effect on fat stem cells, according to previous cell experiment results.

The setting time can be set in 10-minute increments between 30 minutes and 1 hour.

To achieve the full effect of stimulation, more than 30 minutes are needed, and the reason for limiting it to less than 1 hour is that long-term electrical stimulation can cause side effects on the skin.

In other words, the size of the frequency and exposure time were determined within a range where unpredictable abnormal reactions in cells or tissues did not occur.

In addition, the intensity of stimulation must change depending on the skin impedance, but this skin impedance varies from person to person, and even for the same user, it changes depending on the skin condition at the time of use, duration, etc., so even if the same stimulation is applied, the effect may vary from user to user, regardless of age or gender. It should be noted that the above-mentioned microcurrent, frequency, and setting time have been determined because they must vary depending on the patient.

For example, Table 1 shows the impedance measured for each part of the body and the degree of change according to duration.

Table 1 is a table of results of repeated measurements of 6 body parts for 4 subjects, a total of 3 times, for the purpose of simply comparing that differences may exist depending on the user.

As a result of the measurement, not only is there a difference in impedance for each user, but even for the same user, it can be confirmed that the impedance changes when the measurement area changes, and it can be confirmed that the value changes depending on the duration even for the same user and the same area.

In addition, of course, the acne improvement device 100 of the present invention can be used in addition to any one of low frequency, far infrared ray, steaming machine, massage machine, cupping device, braces, wheelchair, and protector.

In addition, the acne improvement device 100 of the present invention can also be used in jewelry for alleviating or improving inflammation that is manufactured including the composition.

Of course, such accessories may include rings, necklaces, pendants, bracelets, anklets, brooches, watches, cuffs, hairpins, hair bands, belts, suspenders, glasses hangers, or tie pins.

Hereinafter, an experimental example using the acne improvement device 100 of the present invention will be described.

Referring to the diagram illustrating the degree of histological evaluation of acne bacteria in Figure 3, group (A) shows inflammation caused by acne in a large area, and in the AMC group to which microcurrent stimulation was applied, inflammation was relatively alleviated and the area was It was seen that this had decreased.
