Description

Energy-based device including roller electrodes {ENERGY BASED DEVICE INCLUDING A ROLLER ELECTRODE}

The present invention relates to energy-based devices.

Recently, energy based devices (EBD) have been widely used for medical or cosmetic purposes. An energy-based device (EBD) refers to a device that applies various types of energy to the human body and uses it for skin care and medical treatment. For example, by using EBD to absorb and promote effective ingredients contained in drugs or cosmetics into the human skin, effects such as regeneration, wrinkle improvement, whitening, moisturizing, and hair loss treatment can be improved.

Transdermal drug delivery (TDD) using EBD is a method for delivering effective ingredients into the skin by administering drugs through the skin, including electroporation, iontophoresis, and arc. Arcporation, microneedle, and sonophoresis are used. Among these, the electroporation method, electroiontophoresis method, and arc discharge perforation method can control the promotion of skin absorption of the effective substance by changing the parameter values of the electrical signal (voltage, current, frequency) used. In addition, the electrical stimulation itself, such as microcurrent, high voltage, low frequency, high frequency, and pulsed electric field, output from EBD may have effects such as regeneration, whitening, wound healing, and pain relief.

As an example, a conventional skin care device is shown in Figure 1. The skin care device 100 shown in FIG. 1 includes a head portion 120 provided with electrodes 130 that apply electrical stimulation to the human body, and a main body portion that accommodates a predetermined driving circuit and power portion that generates an electrical signal. It may be composed of (110). In a conventional skin care device, when the head with two electrodes is brought into contact with the skin, an electrical signal is applied to each electrode to create a perforation in the dead skin cells, thereby promoting drug absorption.

However, this is not intended to limit the present invention to specific embodiments, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

In describing the present invention, if it is determined that a detailed description of related known technology may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, numbers (eg, first, second, etc.) used in the description of this specification are merely identifiers to distinguish one component from another component.

In addition, the following will focus on an example in which the energy-based device including the roller electrode according to the present invention is used as an arcporation device, but is not necessarily limited thereto, and is an electroporation device that applies an electrical signal to the skin surface of the person receiving the treatment. , it can be applied to various energy-based devices such as electric iontophoresis, microcurrent device, low-frequency stimulator, high-frequency stimulator, pulsed electric field stimulator, or these devices.

Arc discharge is a phenomenon in which electricity is emitted in the process of a charged body losing charge, and a potential difference occurs at the electrode, resulting in insulation breakdown. When this arc discharge phenomenon is applied to the skin and an arc discharge based on high voltage discharge is induced, heat energy is instantly generated and micropores are formed in the skin, which is called arc-poration.

When explaining arcporation through FIG. 7, one electrode (ED1) first contacts the skin as a ground electrode. Then, when the other electrode (ED2) approaches the distance (BD) where dielectric breakdown can occur, arc discharge (ARC) occurs, and micropores (MP) are created on the skin surface by the heat energy. do. When both electrodes are in contact with the skin surface, the AC current drops due to high skin resistance, causing current (C) to flow between the two electrodes through the skin. Afterwards, an arc discharge occurs from the moment one electrode (ED1) falls from the skin, and micropores are created in the skin until it exceeds the range where insulation breakdown can occur. Through this mechanism, micropores can be easily created by sweeping, combing, or tapping the skin from the arcporation device.

like this. In order to generate an arc discharge, one electrode must be in contact with the skin while the other electrode must be located within the breakdown distance, so sweep, brush, tap, etc. of the head in the direction of the arrow in Figure 7. There is an inconvenience that must be done. In particular, while the user performs sweeping, brushing, tapping, etc., the location where the arc discharge occurs changes irregularly, making it difficult to uniformly form micropores on the skin surface of the recipient.

The energy-based device according to the present invention is intended to solve the problems of the prior art described above. The user touches the skin with the roller electrode formed on the head of the skin care device and then rolls it to uniformly create micropores in the application area. It is possible to provide an energy-based device that is easy to form and use.

Then, specific details for implementing the present invention will be described with reference to the attached drawings.

Figure 2 schematically shows an energy-based device according to the present invention. As shown in FIG. 3, the roller electrode 200 is disposed in the head portion 120, and the main body portion 110 may have a built-in driving circuit that generates an electrical signal to be applied to the roller electrode 200. In addition, the main body 110 may be provided with a control button 111 for the user to operate the device according to the present invention. The user can operate the driving circuit by manipulating the control button 111 while holding the main body 110 with his hand. The driving circuit built into the main body 110 generates an electrical signal to be applied to the roller electrode 200 and may include, for example, an arc discharge circuit that generates high voltage, a power supply circuit that supplies power, and further control. It may include a control circuit that controls various circuits according to signals input through the button 111. Additionally, the main body 110 can accommodate a battery that can be recharged through an external adapter. In addition, the roller electrode 200 is installed in the head portion 120 so that it can rotate freely. The user uses the device while holding the main body 110 and rolling the roller electrode 200 on the surface of the skin to be treated.

Figure 3 shows a roller electrode 200. The roller electrode 200 is formed in a cylindrical shape, and its opposing ends 210b are mounted on the head 120 so that the circumferential surface 210a can freely roll on the user's skin surface. That is, the roller electrode 200 is installed to be freely rotatable in the rolling direction (R) with respect to the axis (X) mounted on the head unit (120). In addition, a plurality of electrode heads 221 are arranged to be spaced apart from each other on the outer peripheral surface 210a. An electrical signal applied from the driving circuit is transmitted to the electrode head 221 through both ends 210b of the roller electrode 200 mounted on the head 120. One of the plurality of electrode heads 221 first contacts the skin surface and functions as a ground electrode, and the other adjacent electrode is the distance at which dielectric breakdown can occur according to the rolling motion of the roller electrode 200 ( BD) and an arc discharge occurs. In addition, after the two neighboring electrode heads 221 are in contact with the skin surface of the patient, one electrode head 221 is separated from the skin surface by the rolling motion of the roller electrode 200, causing an arc discharge. can be induced. As a result, micropores can be formed uniformly in the dead skin cells. By using an energy-based device equipped with the roller electrode 200 according to the present invention, micropores can be uniformly formed simply by rolling the roller electrode on the skin. In the case of a conventional arcporation device, arc discharge does not occur at a certain location while the user performs sweeping, brushing, tapping, etc., so micropores may be created irregularly. However, the device according to the present invention can cause arc discharge to be generated regularly at a certain location by the rolling motion of the rolling electrode 220, and thus can uniformly form micropores on the user's skin surface.

Figure 4 shows an exploded perspective view to explain the connection state of each part constituting the roller electrode 200. As shown in Figure 4, the roller electrode 200 includes a cylindrical roller case 210. The roller case 210 has a hollow body and may be made of an electrically insulating synthetic resin material, and a plurality of electrode terminals 220 are accommodated therein. Each electrode terminal 220 includes an electrode head 221 exposed through an opening 211 provided in the roller case 210. The electrode terminal 220 may be formed of a metal material with excellent electrical conductivity, or may be formed by coating the surface of a synthetic resin material with an electrically conductive metal layer. Each electrode terminal 220 is arranged to be in close contact with the inner surface of the roller case 210. Additionally, each electrode terminal 220 is arranged along the length of the roller case 210 from one end to the other end. In addition, the plurality of electrode heads 221 formed on each electrode terminal 220 are exposed to the outside through the corresponding opening 211.

In order to ensure that the plurality of electrode terminals 220 are in close contact with the inner surface of the roller case 210, a fixing member 230 may be installed inside the roller case 210. The fixing member 230 may be provided with a seating surface 231 on which each electrode terminal 220 can be seated. The fixing member 230 may be formed of an electrically insulating synthetic resin material. Each electrode terminal 220 disposed on the seating surface 231 of the fixing member 230 is spaced apart from each other and electrically separated from each other. In addition, each electrode terminal 220 is electrically insulated by the electrically insulating roller case 210 and the electrically insulating fixing member 230.

Meanwhile, the plurality of electrode terminals 220 are arranged divided into first group electrode terminals and second group electrode terminals. That is, the first group electrode terminals and the second group electrode terminals are alternately arranged on the outer peripheral surface of the roller case 210 along the rolling direction (R). And, the first group electrode terminals are electrically connected to the first bracket 240a, and the second group electrode terminals are electrically connected to the second bracket 240b. Specifically, a slit 233 is formed at one end of the seating surface 231 in the fixing member 230, and the connection leads 241 formed on the first and second brackets are connected to each electrode terminal 220 through the slit 233. ) becomes electrically conductive by contacting it. In addition, connection leads 243 are formed on the first and second brackets 240a and 240b, and are each electrically connected to the first conductive bearing 250a or the second conductive bearing 250b through the connection lead 243. do. The first and second brackets 240a and 240b may be made of a metal material with excellent electrical conductivity, or may be formed by coating a surface of a synthetic resin material with an electrically conductive metal layer.

The first and second conductive bearings 250a and 250b in contact with the first and second brackets 240a and 240b, respectively, include an electrically conductive outer housing 251, an electrically conductive bearing ball 253, and an electrically conductive outer housing 251. Includes an inner housing (255). Here, the outer housing 251 is in electrical contact with the connection leads 243 provided on the brackets 240a and 240b, and the inner housing 255 is in electrical contact with the conductive contact portion 260. Thus, the electrical signal input to the conductive contact unit 260 may be transmitted to the brackets 240a and 240b via the inner housing 255, the bearing ball 253, and the outer housing 251, respectively.

After sequentially assembling the electrode terminal 220, the fixing member 230, the brackets 240a, 240b, the conductive bearings 250a, 250b, and the conductive contact part 260 inside the roller case 210, the roller case ( After finishing both ends of 210) with a cover 270, it is fixed to the head portion 120 through screws 271. Through this configuration, the roller electrode 200 can be installed on the head portion 120 so that the roller case 210 can freely rotate in the rolling direction (R). In order to more easily understand the connection state of each component arranged inside the roller case 210, in FIG. 5, before fastening the cover 270, the inside of the roller electrode 200 is viewed in the direction II shown in FIG. 4. This drawing is shown, and FIG. 6 shows a view of the inside of the roller electrode 200 when it is cut along the Ⅰ-Ⅰ cutting line in FIG. 4.

Through the configuration of the roller electrode 200 described above, the electrical signal applied from the driving circuit is transmitted through the contact portion 260, bearings 250a, 250b, brackets 240a, 240b, and electrode terminal 220 to the electrode head ( 221). Here, the contact part, bearing, bracket, electrode terminal, and electrode head are all made of electrically conductive material. These components may be formed integrally using a metal material, or may use a synthetic resin material coated with an electrically conductive metal.

When used as a bipolar electrode, the electrical signal applied to the first group electrode terminal may have an opposite sign to the electrical signal applied through the second group electrode terminal. That is, the electrical signal applied to the first group electrode terminal connected through the first bearing 250 and the first bracket 240a, and the second group electrode terminal connected through the second bearing 250b and the second bracket 240b. The electrical signal applied to the group electrode terminal can be driven to have the opposite sign. Electrical insulation is ensured by the fixing member and the roller case so that the electrical signal applied to the first group electrode terminal and the electrical signal applied to the second group electrode terminal are not short-circuited at each preferred transmission stage.

When the device according to the present invention equipped with the roller electrode 200 is first contacted with the user's skin, the electrode head of the first group electrode terminal contacted first can function as a ground electrode, and the roller electrode 200 is rolled. As it rolls on the skin of the patient in the direction R, the neighboring second group electrode terminals become closer to the skin of the user. When the electrode head of the group 2 electrode terminal approaches the skin and the insulation breakdown distance is sufficient to generate an arc discharge, an arc discharge occurs. At this time, the insulation breakdown distance required for the arc discharge may vary depending on the purpose of the skin care device. The distance between the ground electrode (group 1 electrode terminal) and the arc discharge electrode (group 2 electrode terminal) can be changed just by driving the roller electrode. Since can vary, there is no need to control the size of the electrical signal generated by the driving circuit. In addition, the distance between the electrode head provided on the first group electrode terminal and the electrode head provided on the second group electrode terminal is maintained constant, and the location where the first arc discharge occurs and the location where the second arc discharge occurs due to rolling of the rolling electrode. Since can be maintained constant, micropores created on the skin of the recipient can be formed uniformly. Therefore, by using the energy-based device equipped with the roller electrode according to the present invention, micropores can be uniformly formed simply by rolling the roller electrode of the head part on the skin when the user uses the skin care device.

Although the preferred embodiments of the present invention have been described so far, those skilled in the art will be able to implement the present invention in a modified form without departing from the essential characteristics of the present invention. Therefore, the embodiments of the present invention described herein should be considered from an illustrative rather than a limiting point of view, the scope of the present invention is indicated in the claims rather than the above description, and all differences within the equivalent scope are excluded from the present invention.
