Description

A complex skin treatment apparatus and a skin treatment method using the same

The present invention relates to a skin treatment device, and more particularly, to a complex skin treatment device that enables drug penetration into the skin in a non-invasive manner by interlocking plasma and ultrasound, and a skin treatment method using the same.

Wrinkles that occur in the skin are a phenomenon that occurs when the synthesis of collagen and elastin, a fibrous structure that maintains elasticity in the dermal layer of the skin, decreases. The treatment of these wrinkles varies depending on the site and characteristics of the occurrence, and generally, laser treatment or injection therapy such as botox or filler has been used.

Although laser treatment has a high effect of improving wrinkles, it is difficult to access the skin close to the eyes, and the skin around the eyes is so sensitive that there are many side effects. Injection therapy such as Botox or filler is effective in both brows, wrinkles around the eyes, and nasolabial folds around the mouth by injecting drugs or supplements into the skin through injection. There is a problem that the effect is reduced.

Recently, it has been found that plasma energy has an excellent effect on skin regeneration. Plasma means that molecules contained in the gas collide with each other, causing some of the outermost electrons to fall, thereby forming an ionized gas containing positive and negative ions.

The plasma for skin regeneration does not directly contact the skin, but transmits energy only to the tissue structure in the skin to be treated, so that it does not damage the skin epidermis, which acts as a protective film until new skin is regenerated. In addition, since the skin is continuously regenerated rather than a temporary effect, it is possible to see an effect that continues to improve over time. Therefore, there is a comprehensive skin care treatment effect such as remarkable wrinkle improvement, elasticity increase, skin tone, texture, and pigment improvement, and there is no pain during treatment, especially for curved skin shapes such as around the mouth and cheekbones around the eyes. It provides the advantage of being able to treat in a balanced way.

However, in the conventional skin treatment method using plasma, plasma treatment is performed after first injecting a drug into the skin using an injection needle. Accordingly, the conventional plasma skin treatment apparatus has an invasive configuration in which an injection needle is disposed in a portion in contact with the skin of a patient.

Accordingly, in the conventional plasma skin treatment apparatus, a hygiene problem may occur due to an injection needle, and there is a problem that may give a patient a feeling of fear due to the fine needle of the injection needle.

Moreover, since the conventional plasma skin treatment apparatus does not have a configuration for treating harmful gases or waste products caused by plasma generation, there is a case that a problem due to harmful gases occurs.

An object of the present invention is to solve the above-described problems, and to provide a complex skin treatment apparatus and a skin treatment method using the same, which enables drug penetration into the skin in a non-invasive manner by interlocking plasma and ultrasound.

A complex skin treatment apparatus according to an embodiment of the present invention includes: a main body; And a handpiece connected to the main body through a connection part, injecting a drug in a non-invasive form to the user's skin under the control of the main body, and providing at least one of plasma stimulation and ultrasonic vibration to allow the drug to penetrate into the skin. Includes.

Here, the handpiece is a hollow body; And a tip module inserted into and coupled to one end of the body, wherein the tip module includes a plasma tip module that generates plasma and applies it to the skin, and an ultrasonic vibration tip module that generates ultrasonic vibration and applies it to the skin. It characterized in that it is combined with.

The skin treatment method according to an exemplary embodiment of the present invention may be performed using a complex skin treatment apparatus including a handpiece that provides at least one of plasma stimulation and ultrasonic vibration to the skin.

Such a skin treatment method includes: placing the handpiece adjacent to the user's skin, applying plasma to the skin through the handpiece, and spraying a drug in a non-invasive manner; Forming a hole in the skin by plasma so that the drug penetrates into the skin; And applying ultrasonic vibration to the skin through the handpiece so that the drug further penetrates into the skin.

The complex skin treatment apparatus according to the present invention may stimulate the skin by interlocking plasma and ultrasonic waves so that the drug sprayed on the skin in a non-invasive manner penetrates into the skin.

Accordingly, the complex skin treatment device of the present invention applies plasma stimulation to the skin and promotes the regeneration of fibroblasts and cells of the skin dermal layer, collagen production, etc. by the drug penetrating into the skin to treat and improve the user's skin. can do. In addition, the effect of skin treatment and improvement can be maximized by applying ultrasonic vibration stimulation to the skin to allow the drug to penetrate deeper inside the skin.

Accordingly, the control unit 101 of the main body 100 may control the operation of the tip modules 220 and 240 of the handpiece 200 through the connection part 210.

3 and 4 are exploded perspective views according to an embodiment of the tip module of FIG. 2. Here, Figure 3 shows the configuration of the plasma tip module 220 coupled to one end of the handpiece 200, Figure 4 shows the configuration of the ultrasonic vibration tip module 240 coupled to one end of the handpiece 200 .

First, as shown in FIG. 3, the plasma tip module 220 includes components for generating plasma between the first cover case 221 and the second cover case 225, for example, a plasma application unit 224, piezoelectric The device 223 and the plasma electrode may be arranged and configured with the plasma electrode 222.

The first cover case 221 may be coupled to one end of the body 201 of the handpiece 200. At this time, the first cover case 221 is coupled while surrounding the outer surface of the drug container 230 coupled to the body 201, and for this purpose, a portion inserted into the body 201 is extended in a hollow cylindrical shape. Can be formed. In addition, a drug injection hole through which drugs from the drug container 230 are discharged, for example, a first injection hole 221a, may be formed in the center of the first cover case 221. The drug injection hole may also be formed in the plasma electrode 222, the piezoelectric element 223, and the second cover case 225 to be described later.

The plasma electrode 222 may be disposed on one surface of the first cover case 221. The plasma electrode 222 may generate a predetermined plasma from a signal transmitted from the main body 100 through the connection part 210, for example, the signal cable 211, for example, a voltage for plasma discharge. The plasma generated by the plasma electrode 222 may be transmitted to the plasma applying unit 224 coupled to surround the outer peripheral surface of the piezoelectric element 223. In addition, a second injection hole 222a corresponding to the first injection hole 221a may be formed in the center of the plasma electrode 222.

The piezoelectric element 223 may be disposed on one surface of the plasma electrode 222. The piezoelectric element 223 may vaporize the drug provided through the first injection hole 221a of the first cover case 221 and the second injection hole 222a of the plasma electrode 222. The drug vaporized by the piezoelectric element 223 may be injected in the form of a gas through the third injection hole 223a formed in the center of the piezoelectric element 223.

The plasma applying unit 224 may apply the plasma delivered from the plasma electrode 222 to the user's skin through the opening of the second cover case 225. Plasma applied to the user's skin from the plasma applying unit 224 may form a hole having a predetermined depth from the surface of the skin to the dermal layer. Thus, the drug discharged from the drug container 230 through the first cover case 221, the plasma electrode 222, the piezoelectric element 223, and the second cover case 225 is inside the skin through a hole formed by plasma. Can penetrate into. In the plasma application unit 224, two electrodes separated from each other may be formed in a donut shape.

I can. In addition, the plasma tip module 220 may vaporize the drug in the drug container 230 and spray it onto the user's skin. At this time, a hole of a predetermined depth, such as a hole from the skin surface to the dermal layer, is formed in the user's skin by the plasma generated by the plasma tip module 220, and the drug injected into the hole is injected to penetrate the skin. I can. Accordingly, the regeneration of fibroblasts and cells of the dermal layer by the drug, and collagen production, etc. are promoted, thereby enabling the user's skin treatment and improvement.

On the other hand, when plasma is generated in the plasma tip module 220, harmful gas such as ozone (O3) may be generated, thereby threatening the user's health. Accordingly, the handpiece 200 of the present embodiment may suck harmful gases or wastes through the suction pipe 213 connected between the body 201 and the body 100 and discharge them to the outside.

The vibration generated by the ultrasonic vibrator 245 may be applied to the skin through the second cover case 225. Accordingly, the drug that has previously penetrated into the skin by the plasma tip module 220 may penetrate deeper inside the skin by the vibration generated by the ultrasonic vibrator 245. Therefore, it is possible to increase the skin treatment and improvement effect of the user by the drug.

That is, the ultrasonic vibration tip module 240 of the present embodiment generates heat due to friction inside the skin by applying vibration to the skin, and increases the temperature of the skin by this heat so that the drug penetrates deeper into the skin. I can. Therefore, it is preferable that the ultrasonic vibration tip module 240 is used after infiltrating the drug into the skin using the plasma tip module 220 described above.

In other words, after the drug is injected into the skin and the drug is penetrated into the skin using the plasma tip module 220, the previously penetrated drug is further removed from the skin by using the ultrasonic vibration tip module 240 by replacing the tip module. By allowing it to penetrate deep, it is possible to maximize the effect of the user's skin treatment and improvement by the drug.
