The skin improvement agent injection unit 250 is not necessarily installed inside the plasma electrode 221, but may be installed outside or at another position of the plasma electrode 221.

As illustrated in FIG. 4, the housing 202 has a substantially cylindrical shape, and an annular plasma injection hole 216 and a skin improvement agent injection hole 255 may be formed at a front end surface of the housing 202 in contact with the skin of the subject.

The ground electrode corresponding to the plasma electrode 211 may be a skin of an operator or may be separately installed.

When the gas is supplied through the gas passage 213, the RF frequency power is supplied to the plasma electrode 211 to generate a plasma due to dielectric barrier discharge between the plasma electrode 211 and the skin or ground electrode. The generated plasma is discharged through the plasma injection hole 216 and then penetrates into the skin of the subject to exert a predetermined therapeutic effect.

The shape of the generated plasma may vary depending on the shape of the plasma electrode 211 or the ground electrode, and in the embodiment of the present invention, the annular plasma may be generated due to the annular plasma electrode 211. Of course, other shapes of the plasma electrode 211 or the ground electrode can be used.

FIG. 10 is a diagram illustrating a plurality of modular plasma generating units 210a, 210b, 210c, and 210d disposed along an annular plasma injection hole 216. Instead of forming the plasma injection holes 216 in an annular shape, as illustrated in FIG. 11, the plasma injection holes 216 are formed at positions corresponding to the tips of the respective plasma generators 210a, 210b, 210c, and 210d, respectively. You may. Even in this case, the skin improvement injection part 250 may be installed inside the plurality of modular plasma generating parts 210a, 210b, 210c, and 210d as shown in the drawing, or alternatively, may be installed on the outside thereof.

Hereinafter, a skin treatment method using a skin treatment apparatus according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 12.

First, the skin improver supply unit 130 is activated to spray a predetermined skin improver aqueous solution to the skin treatment area through the handpiece 200.

In this case, when a plurality of types of skin improver aqueous solutions are stored in the main body 100, the user may select a skin improver to be sprayed through the input unit 140, or select two or more skin improvers to be sprayed by mixing.

On the contrary, when the skin improver injection command is input by the user, the controller 180 properly controls the flow control units 137a, 137b, and 137c to mix two or more types of skin improver aqueous solutions at a preset ratio to the skin improver injection unit ( 250).

In addition, when the user selects a treatment type through the input unit 140, the controller 180 may supply two or more kinds of skin improver aqueous solutions to the skin improver injection unit 250 at a predetermined ratio corresponding to the selected treatment type. . (ST11)

After the injection of the aqueous solution of the skin improver, the gas supply unit 120 is started to supply discharge gas and / or catalyst gas near the end of the plasma electrode 211 through the gas flow passage 213 of the handpiece 200. . Subsequently, the RF generator 110 is started to supply RF frequency power to the plasma electrode 211.

For example, the gas supply unit 120 may supply argon (Ar) at a flow rate in the range of 0-30 SLM (Standard Liter per Minute), and nitrogen (N2) may be supplied at a flow rate in the range of 0-10 SLM. On the other hand, the power applied to the RF generator 110 is preferably 1KW or less. (ST12)

In this way, plasma is generated due to dielectric barrier discharge between the plasma electrode 211 and the skin, and the generated plasma is discharged to the outside of the handpiece 200 through the plasma injection hole 216 and supplied to the skin of the subject.

Plasma ions generated by the plasma treatment apparatus can easily penetrate the dermal layer, so when plasma is supplied, the skin improver ions sprayed onto the skin can also easily penetrate the skin under the influence of plasma.

Therefore, it is possible to obtain a much faster treatment effect compared to the case where only the skin improver solution is applied to the skin. (ST13)

After sequentially supplying the skin improver and the plasma through the above process, the operation of the RF generator 110 may be stopped and the treatment may be terminated.

On the other hand, it is not necessary to end the treatment after supplying the skin improver and the plasma sequentially, and as shown in the drawing, the skin improver may be supplied once more after the plasma is supplied.

This is because the penetration of pharmacological components through the barrier of the skin is facilitated due to the action of plasma ions, so that the skin penetration rate of the skin improver can be further increased by supplying an aqueous solution of the skin improver having a skin treatment and / or regeneration effect.

In this case, the second skin improver supplied may be a different kind from the one supplied initially, or may have the same ingredients but different mixing ratios. (ST14)

The process of ST11 to ST13 or the process of ST11 to ST14 may be automatically performed under the control of the controller 180. In addition, the controller 180 may set the processes of ST11 to ST13 or the processes of ST11 to ST14 as one cycle, and may perform two or more cycles of treatment.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and may be modified or modified in various forms in a specific application process.

As an example, in the above-described embodiment, although the RF generator 110 is provided in the main body 100, a plurality of RF generators 110 may be installed in the main body 100.

For example, as shown in FIG. 13, the main body 100 includes first to fourth RF generators 110a, 110b, 110c, and 110d, and the handpiece 200 includes first to fourth RF generators. First to fourth plasma generators 210a, 210b, 210c, and 210d connected to the 110a, 110b, 110c, and 110d may be installed.

At this time, the RF frequencies generated by each of the RF generators 110a, 110b, 110c, and 110d may be the same or different. By appropriately selecting or combining the RF frequencies, the surgeon adjusts the density of plasma, the type and density of reactive species, and performs appropriate and active treatment according to the type of treatment, skin condition, lesion size, and type of pre-supplied skin improver. Can be.

As another example, the plurality of plasma generators 210a, 210b, 210c, and 210d provided in the handpiece 200 may be fixed to the housing 202 or installed to be movable.

For example, as illustrated in FIG. 14, a plurality of guide rails 291, 292, 293, and 294 are installed inside the housing 202, and the plasma generating units 210a, 210b, 210c, and 210d are movable to each guide rail 291, 292, 293, and 294. can do. In this case, the module housings 209 or the plasma electrodes 211 of the plasma generators 210a, 210b, 210c, and 210d may be movably coupled to the guide rails 291, 292, 293, and 294.

Although not shown in the drawings, the handpiece 200 includes a motor for moving the module housings 209 or the plasma electrodes 211 of the plasma generators 210a, 210b, 210c, and 210d along the guide rails 291, 292, 293, and 294. May be installed.

In addition, the handpiece 200 may be provided with a displacement sensor for detecting the displacement of the plasma generating unit (210a, 210b, 210c, 210d) or the plasma electrode 211. In this case, the controller 180 of the skin treatment apparatus may change the RF frequency generated by the RF generator 110 in response to the detection result of the displacement sensor.

For example, as shown in FIG. 14B, when the plurality of plasma generators 210a, 210b, 210c, and 210d move from the center to the outside, the handpiece 200 is moved away from each plasma electrode 211. Since the lower plasma density is lowered, the controller 180 may adjust the RF frequency in a direction of increasing the density of the plasma.

On the contrary, as shown in FIG. 14A, when the plurality of plasma generating units 210a, 210b, 210c, and 210d move toward the center, the plasma between the lower portions of the handpiece 200 is closer to each other. Since the density is increased, the controller 180 may adjust the RF frequency in a direction of decreasing the density of the plasma.

As described above, the present invention may be modified or modified in various forms in a specific application process, and the modified or modified embodiments may be included in the scope of the present invention if they include the technical idea of the present invention disclosed in the claims to be described below.
