[0001] Description [0002] Plasma Roller for skin treatment [

The present invention relates to a plasma generating apparatus for skin treatment. More particularly, the present invention relates to a configuration of a plasma generating apparatus that removes various bacteria that act on the skin to cause skin diseases, and regenerates the skin tissue through activation of the skin tissue. Therefore, it is a technology related to the construction of a plasma generating apparatus for smoothly generating plasma on skin for treatment of skin diseases and regeneration of skin tissue.

Plasma is being studied for applications in the biomedical field. In particular, the plasma has various sterilizing effects in addition to the regeneration effect of skin tissue due to activation of skin cells. The generation of plasma in the atmosphere is facilitated by discharging using a dielectric barrier discharge method using an AC high voltage.

Plasma treatment of bacterial skin diseases utilizes the sterilization effect that the plasma reacts with bacteria to kill bacteria. An example of such plasma sterilization treatment is athlete's foot, eczema, and the like. In addition, plasma treatment can be applied to cosmetics such as skin damage such as scratches and burns, aging skin due to skin coloring or wrinkles of skin, and in this case plasma treatment is utilized for regenerating effect of skin tissue. Activation of other skin tissues is various chronic skin diseases, such as atopy, acne, and the like.

On the other hand, there are various types of plasma generating apparatuses. Among these, the atmospheric pressure plasma generating apparatus is applicable to the biological treatment of plasma because it can discharge the plasma without supplying a separate discharge gas, and is relatively simple in structure and convenient to handle. When a beauty / medical appliance is manufactured using such a plasma generating device, it is necessary to supply a power source to be supplied to the household power source. In particular, a power source can be supplied to a battery, .

Generally, a plasma generating apparatus employing a dielectric barrier discharge method is manufactured by manufacturing an electrode with a metal material having good electrical conductivity, applying an AC high voltage thereto, and coating the surface of the metal electrode with a dielectric layer having a constant thickness. When the dielectric layer covering the metal electrode is brought into contact with the skin, a plasma is generated between the skin and the metal electrode surface, and the skin is treated with plasma. Therefore, in order for plasma to be generated by contacting the surface of the metal electrode coated with the dielectric layer to the skin, a predetermined gap should be maintained between the metal electrode surface and the skin. However, when the electrode surface is brought into contact with the skin, there is a problem that the electrode surface is adsorbed on the skin, and the plasma discharge space disappears. Accordingly, efforts to artificially maintain a predetermined interval during the plasma procedure are inconvenient to use.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, a minimum unit of a single dielectric barrier discharge plasma generator is shown, so that the concept of dielectric barrier plasma discharge can be easily understood.

In the dielectric barrier discharge, a metal electrode is used as a core, a periphery thereof is surrounded by a dielectric material to form a dielectric barrier, and an AC high voltage is applied to the metal electrode to discharge the plasma as a ground electrode. That is, the plasma is discharged between the metal electrode and the object to be processed. The plasma generating apparatus of the present invention will also discharge plasma at the plasma roller 100 using the same structure and principle as those of FIG. In this embodiment, the dielectric barrier discharge plasma generator is constructed in the same structure as that of a wire, and a commercial high voltage wire can be used as a source of the dielectric barrier plasma. That is, according to the present invention, plasma processing can be performed by rolling a roller on the skin by making a plasma roller. The high voltage wire is wound on the roller body to discharge plasma toward the skin at the end of the roller, Respectively.

The plasma roller 100 according to the present invention is shown in FIGS. 2 and 3. FIG.

2 shows an outer appearance of the plasma roller 100 according to the present invention. The plasma roller 100 has a handle such as a general roller, and a roller housing connected to the handle and fixing the cylindrical roller. The cylindrical roller is wound with a wire 120 as a dielectric barrier discharge source of the structure shown in Fig. 1, and the electric wire 120 is exposed through the inside of the roller handle and connected to the power source. The plasma roller 100 shown in FIG. 2 is used to hold a user's handle and use a plasma emitted from an end of a wire 120 wound on a roller while rolling a roller or the like on the user's skin or scalp. Therefore, it is very convenient to use.

FIG. 3 shows a transparent perspective view in order to more easily understand the structure of such a plasma roller 100.

A passageway 140 is formed in the handle of the roller so that the electric wire 120 can be embedded therein. Such a passage is formed in the housing 130 for fixing the cylindrical roller 110, This is possible. A core 160 is located at the center of the roller 110 and a connecting member for connecting the core 160 to the housing 130 rotatably connects the core 160. A cylindrical roller 110 is disposed on the outer side of the core 160 and a hole through which the electric wire 120 can pass is provided at an end of the kogtong 160 and an end of the cylindrical roller 110. Therefore, the electric wire 120 is drawn through the internal passageway 140 of the roller and passes through the internal passage of the housing 130 which fixes the roller 110, is drawn into the core 160, Passes through the hole 165 and out of the core 160 and passes through the hole 115 at the end of the roller 110 to be drawn out to the surface of the roller 110. In Fig. 4, the path of the electric wire 120 is shown in an easy to understand manner. The electric wire 120 arriving at the surface of the roller 110 through this path is wound on the surface of the roller 110 and the final end of the electric wire 120 is floated in a state of being adhered to the surface of the roller 110. That is, the end of the electric wire 120 drawn out to the outside of the knob is connected to the power connection part 150 so that the electric power is applied, but the other end of the electric wire is wrapped around the roller 110 and is finished in contact with the surface of the roller 110 . The electric wire 120 for plasma discharge serves also as a connecting member for connecting the housing 130, the core 160, and the cylindrical roller 120. Accordingly, the cylindrical roller 120 can be squeezed about one turn in accordance with the pushing operation and operated by the reciprocating motion. The rolling range is somewhat limited. However, since the roller 120 is moved to a desired region in a practical skin treatment, the operation range can be sufficiently satisfied. In order not to restrict the rolling range of the rollers, a general fixing member may be separately used to rotatably assemble the core, the roller, and the housing, and the electric wire 120 may be wound around the roller 120 and drawn out into the passageway 140 of the handle. However, the present embodiment can be optimally seen in that it satisfies the required operating range in addition to the simplification of fabrication.

When a power source is applied to an end portion of the electric wire 120 drawn to the handle side and rubbed against the skin, the plasma roller 100 configured as described above forms a gap between the electric wire 120 and the skin as a discharge electrode by using the skin as a kind of ground electrode, Is discharged. A high voltage is required for plasma discharge, and a pulsed power supply or an AC power supply of several Hz to several tens of kHz is required. The voltage of such an alternating current power source is usually several kV, and the DC-AC inverter 200 is applied. By applying the inverter, a household power source of 110 V or 210 to 220 V of 60 Hz can be used as it is in the plasma roller 100, and a portable battery can be used at the same time. A power supply of 12 V DC or 24 V DC, which is the power source of the battery or rechargeable battery, is also applicable. Therefore, the plasma roller 100 of the present invention is very convenient for use.

Hereinafter, the discharge of the plasma and its treatment in the case of performing the operation on the skin with the plasma roller 100 according to the present invention will be described in more detail with reference to FIG.

The plasma roller 100 of the present invention discharges plasma between the surface of the skin and the lower surface of the metal wire with the skin as the ground electrode surface and the metal wire inside the wire 120 as the discharge electrode. Accordingly, if the plasma roller 100 approaches the skin and is spaced at a predetermined interval, the plasma is discharged. However, the plasma roller 100 of the present invention solves this inconvenience because it is inconvenient to use an interval to maintain the gap. That is, the user of the plasma roller 100 can perform the operation while keeping the plasma roller 100 in contact with the surface of the skin. As shown in FIG. 5, even when the wire 120 is in contact with the surface of the skin, the wire 120 wound around the cylindrical roller 110 has a predetermined gap between the surface of the skin and the surface of the wire 120 before and after the contact with the skin This gap becomes a discharge space. Therefore, it is not necessary to perform the procedure while maintaining a constant gap with the skin surface for the plasma treatment, so that the self-operation can be performed very conveniently. Since the plasma roller 100 manufactured by the simplified manufacturing method can also be rolled about one turn, it can cover a sufficient range by rotating the substrate by about one revolution in the forward and backward directions, and then moving the position after performing the procedure.

The structure of the plasma roller 100 of the present invention may be modified as shown in FIG.

That is, a plurality of roller wheels 170, which protrude more than the electric wire 120, are arranged in the cylindrical roller 110 winding the electric wire 120. The roller wheel 170 protruding from the outer circumference of the cylindrical roller 110 and having a height of about 'd' relative to the outermost surface of the wire 120 is spaced apart from the wire 120 by a distance d Even if the user rubs the plasma roller 100 against the skin, the plasma discharge space is formed by the distance d. The electric wire 120 is wound on the surface of the cylindrical roller 110 between the roller wheels 170 provided at intervals in the body of the cylindrical roller 110 and the electric wire 120 is fed to the cylindrical roller 110 through the roller wheels 170 at the point where it should go to the next section to place a wiring path through the roller wheel 170 in the cylindrical roller body. In the plasma roller 100 having the above-described structure, the rotation of the roller 170 can be performed by 360 ° or more, which is more convenient.

The distance d may be set to about 1 to 3 mm.

FIG. 7 (a) is a photograph of the plasma roller 100 implemented in accordance with the above, and FIG. 7 (b) is a photograph showing a process being performed using the same.

In this way, a plasma roller can be realized which can be easily performed by the user on the skin or the scalp.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.
