Description

Operating method using microcurrent stimulation apparatus for wound treatment}

The present invention relates to a method of operating a microcurrent stimulator for wound healing that can rapidly recover skin damage regardless of the type of skin damage by microcurrent stimulation.

Skin is the largest organ covering the outside of the human body and is composed of epidermis, dermis, and subcutaneous tissue. The epidermis is mainly composed of keratinocytes of stratified squamous epithelium. The dermis is a layer between the epidermis and subcutaneous tissue, and is composed of matrix proteins such as collagen fibers and elastic fibers and fibroblasts, and includes blood vessels, lymphatic vessels, nerves, and accessory organs such as sweat glands, sebaceous glands, and hair.

The skin responsible for protecting the body from the external environment can be frequently exposed to trauma and burns, which also occurs when surgery is required. In case of damage to the skin, medically, it is treated by first considering inducing natural healing through dressing, but if the degree of damage is severe, surgical healing such as autologous skin grafting or flap surgery is required. In the case of self-skin grafting or flap surgery, a graft is required, which may be temporary, but causes new damage to the skin donor site. There is a difference in the degree of formation of scars that can occur due to damage to the skin depending on the healing speed. Therefore, inducing rapid natural healing of the skin is very meaningful in that it can provide an opportunity to reduce the number and area of surgery even in the case of skin damage requiring surgery, and ultimately reduce the formation of scars.

Hereinafter, a microcurrent stimulator for wound healing according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the microcurrent stimulator for wound healing of the present invention is composed of a power supply unit 100 for supplying power and power supplied from the power supply unit 100. The microcurrent generating unit 200 that generates microcurrent, the microcurrent providing unit 300 that delivers the microcurrent generated by the microcurrent generating unit 200 to the skin, and the microcurrent providing unit 300 are applied to the skin. A pad fixing unit 400 to be attached, a microcurrent manipulation unit 500 for manipulating the microcurrent generating unit 200, an operating state display unit 600 displaying an operating state of the microcurrent generating unit 200, The control unit 700 recognizes the operation of the current control unit 500 and controls the microcurrent generator 200 and the operating state display unit 600.

The power supply unit 100 converts commercial power input from the outside into appropriate power and supplies it to the microcurrent generator 200 .

The microcurrent generator 200 generates a microcurrent by alternating current using input power.

The microcurrent providing unit 300 includes a plurality of wires 310 respectively connected to the microcurrent generating unit 200 and a plurality of electrode pads 320 respectively connected to the wires 310 .

Each of the electrode pads 320 is provided with one electrode, and the + side and - side are repeated by the alternating current applied from the microcurrent generator 200 to provide microcurrent to the skin.

Therefore, microcurrent is applied while the electrode pads 320 are in contact with the skin and are located on both sides of the wound on the skin. At this time, since the microcurrent applied from the electrode pads 320 flows past the wound, the blood flow condition of the wound can be improved while giving a fine stimulus to the wound, which can help wound healing.

The pad fixing part 400 may be composed of a band that is fixed while wrapping the electrode pad 320 in a state of being in close contact with the skin.

In addition, the pad fixing part 400 may be formed of an adhesive tape formed along the circumference and attached to the skin.

In addition, the pad fixing part 400 may be configured as a cap having elasticity so that the electrode pad 320 is vacuum-fixed to the skin in a fixed state.

Such a cap is made of rubber or silicon material, and the inner space is opened to the lower side, and the electrode pad 320 is in contact with the top and the sponge 410 is in contact with the skin at the bottom while being moistened with moisture while being accommodated in the inner space. include

In addition, fixing protrusions 420 are formed to be distributed in the lower portion of the inner space of the cap so that the sponge 410 inserted into the inner space can be caught and fixed by the fixing protrusions 420 .

Therefore, when the user wets the sponge 410 with moisture and then presses the cap to reduce the inner space while releasing the pressure of the cap while in close contact with the skin, the cap expands and the inner space expands to become a vacuum state. The cap is attached to the skin. At this time, the microcurrent applied to the electrode pad 320 may be transmitted to the skin.

The microcurrent control unit 500 includes an operation unit 510 that operates the microcurrent generator 200, a current amount control unit 520 that controls the current amount of the microcurrent generated by the microcurrent generator 200, and It includes an operation mode selection unit 530 for selecting a set operation mode.

The operating unit 510 may be configured as an on/off switch. Accordingly, when the user manipulates the on/off switch, the microcurrent generator 200 may be operated or stopped.

The current amount control unit 520 may be composed of a radio button for manipulating the frequency Hz. Therefore, the user can directly manipulate the radio button to increase or decrease the current amount of the microcurrent. That is, since the current amount control unit 520 includes an inverter, the amount of current can be adjusted from 2 Hz to 20 Hz of 2 mA to 10 mA through pulse width modulation.

In this way, by adjusting the number of current pulses per unit time by changing the frequency, the intensity of stimulation by the current applied to the skin can be adjusted by changing the amount of current. For example, if the wound is slight, the amount of current may be adjusted to be small at a low frequency of 2 Hz, and if the wound is severe, the amount of current may be adjusted to be increased at 20 Hz.

In addition, since different amounts of current can be generated by different Hz, it can help wound healing by stimulating the skin with different wave stimulation.

The operation mode selector 530 may select an operation mode set to generate microcurrent regularly or irregularly. Alternatively, an operating mode may be selected such that the current amount of the microcurrent is regularly or irregularly increased or decreased. Accordingly, the microcurrent may be regularly or irregularly provided to the patient's skin according to the user's selection, and the current amount of the microcurrent may be provided regularly or irregularly while changing high or low current.

The operating state display unit 600 may be composed of an LED that is turned on when the microcurrent generator 200 is operated and turned off when the microcurrent generator 200 is not operated. Therefore, the user can check the LED with the naked eye to know the operating state of the microcurrent generating unit 200 .

In addition, the controller 700 includes a manipulation recognition unit 710 for recognizing manipulation of the microcurrent manipulation unit 500, a current manipulation unit 720 for manipulating the operation unit 510 of the microcurrent manipulation unit 500, and an operating state. When the display operation unit 730 and the operation recognition unit 710, which operate the display unit 600, recognize the operation, the current operation unit 720 is operated, and the current operation unit 720 is the operating unit of the microcurrent operation unit 500. A manipulation unit 740 for manipulating the display operation unit 730 when the 510 is operated is included.

In this way, the microcurrent generator 200 can be manipulated by the control unit 700 according to the user's manipulation.

In addition, the present invention includes a resistance sensing unit 800 that senses the resistance of the microcurrent generated by the microcurrent generating unit 200 and provided to the microcurrent providing unit 300 . The resistance sensing unit 800 may be configured as an resistance meter that senses a resistance value.

Further, the resistance sensing unit 800 may include a pad attached to the skin in a state positioned between the electrode pads 320 to sense current, and an ammeter to calculate a resistance value from a change in current sensed by the pad.

In addition, the control unit 700 compares the resistance recognition unit 750 for recognizing the resistance detected by the resistance sensing unit 800, the reference resistance management unit 760 for storing and managing the reference resistance, and the recognized resistance with the reference resistance. and an information transmission unit 770 for transmitting the determined resistance information to the operation unit 740.

The aforementioned control unit 740 is configured to operate the current control unit 720 based on the transmitted resistance information.

Accordingly, the microcurrent generator 200 is controlled by the resistance sensing unit 800 to control the current amount of the microcurrent transmitted to the skin through the electrode pad 320 .

Meanwhile, the control unit 700 includes a clock 780 that provides time, a time setting unit 790 that sets the operating time, and a time counting unit 900 that counts the set time based on the clock 780. do.

The control unit 740 is set so that the current control unit 720 stops the operation unit 510 of the microcurrent control unit 500 when the time counting unit 900 completes the counting.

As shown in FIG. 5, a preparation step (S10) of preparing by fixing the microcurrent providing unit 300 for providing microcurrent to the skin to the pad fixing unit 400, and coupled to the pad fixing unit 400 An electrode pad positioning step (S20) of locating the microcurrent providing unit (300) around the wound, and a power supplying step (S30) of supplying power to the microcurrent generating unit (200) using the power supply unit (100); A microcurrent control step (S40) of adjusting the amount of microcurrent of the microcurrent generator 200 through the microcurrent control unit 500, and an operating time setting step of setting the operating time of the microcurrent generator 200 (S50). ).

Hereinafter, a process of helping wound healing using the present invention will be described.

First, the microcurrent providing unit 300 is prepared by fixing it to the pad fixing unit 400. That is, the sponge 410 is inserted into the pad fixing part 400 so that it is caught and fixed by the fixing protrusions 420 . After that, the sponge 410 is wetted with moisture.

Then, the pad fixing parts 400 are placed on both sides of the wound. In addition, when the cap of the pad fixing part 400 is pressed so that the inner space is reduced, and the pressurization of the cap is released while in close contact with the skin, the cap expands and the inner space expands to become a vacuum state, so the cap is attached to the skin. .

Subsequently, power is supplied to the microcurrent generator 200 through the power supply unit 100 . The amount of current of the microcurrent may be adjusted using the microcurrent control unit 500 or an operation mode may be selected.

At this time, since the LED of the operating state display unit 600 is turned on, it can be confirmed that the microcurrent of the microcurrent generating unit 200 is transferred to the microcurrent providing unit 300 and provided to the skin.

Therefore, since the microcurrent is periodically or intermittently provided around the wound, the state of blood flow in the wound can be improved, which can help wound healing.

<Experimental example>

After excising the skin with an area of 2 cm x 2 cm on the back of the rat, microcurrent electrodes were applied for 30 minutes at the same time every day using two frequencies of 2 mA current, as shown in Table 1.

2Hz 20Hz 2mA Experimental Example 1 Experimental Example 2

<Realtime-PCR results> After 1, 3, and 7 days, the mice were sacrificed, and the skin tissue of the entire excised experimental site was recovered, RNA was separated and purified from the tissue, and pro-inflammatory genes (interleukin-1β, - 6, 12β, MCP-1) and anti-inflammatory gene (interleukin-10) were performed by real-time PCR and shown in FIG. 6 .

As a result, as shown in FIG. 6, when microcurrent (2Hz, 20Hz) was applied for 7 days after full-thickness resection, interleukin-6 and 12β related to inflammation were reduced, and interleukin-10 related to anti-inflammation was reduced. It was confirmed that the expression increased.

<H&E staining result>

After applying stimulation of 2 Hz and 20 Hz with a current of 2 mA until the 7th day, the animals were sacrificed and the skin tissue was stained and shown in FIG. 6 .

In addition, when compared with normal skin, it was not confirmed that blood vessels were formed on the 3rd and 7th days in the case of the tissue of the full-thickness resection site to which electrical stimulation was not applied. However, when 2 and 20Hz stimulation was applied, it was confirmed that many blood vessels were formed.

Even after 17 days, it was confirmed that blood vessels were formed in the tissue of the full-thickness excision site (results not shown).

<Pan-cytokeratin immunostaining result>

In order to confirm that the wound was healed and the epidermal layer of the skin was also well made, immunostaining was performed on the skin tissue on the 7th and 17th days using a pan-cytokeratin antibody specific for skin keratinocytes, and shown in FIGS. 8a and 8b, respectively. .

As can be seen in the photographs of FIGS. 7a and 7b, it was observed that epidermal formation on the wound site proceeded faster in the group to which microcurrent was applied than in the only FT (control) skin tissue on the 7th and 17th day, especially this phenomenon In the 20Hz group, it was confirmed that epidermal formation was clearly formed.

As described above, the present invention can be helpful in healing wounds of various degrees by providing different amounts of microcurrent to the skin of the human body, so it can be said to be a very useful invention that can be widely used in the related field.
