Apparatus for Managing Skin Using Plazma and Driving Method Thereof}

The present invention relates to a plasma skin care device and a method of driving the device, and more particularly, to induce plasma to a user's skin in a plurality of pre-radiation methods in order to reduce the amount of ozone while increasing the area affecting the skin. The present invention relates to a plasma skin care device and a method of driving the device.

As the anti-aging industry grows, the market for facial and skin care medical devices is growing together. According to a 2015 report by a domestic researcher, the skin care medical device market is growing at an annual average level of 7%, and the market size will increase to $ 3.6 billion in 2017. This is because women's advancement into society and awareness of their appearance have not only changed, but the demand for skin beauty is increasing, as hospitals and clinics, such as dermatologists and plastic surgeons, are trying to resolve their management difficulties.

Currently, skin care medical devices are introducing various devices using laser, ultrasound, and plasma in a non-ablation manner. In particular, recently, portable beauty devices using plasma have been introduced one after another, and many ordinary people are increasingly interested in skin care and treatment.

Plasma is called a fourth material other than solid, liquid, and gas, and can generally be artificially generated through arc induction based on high voltage discharge. When plasma is applied to the skin, the plasma penetrates into the skin to sterilize harmful bacteria, and at the same time promote the production of cells to increase skin regeneration ability. In addition, it delivers energy to the skin tissue structure to help manage sensitive skin troubles and relieve itching by drying, and has the advantage of speeding up recovery with little scarring during wound healing.

Conventional skin care devices using plasma (e.g., DBD (Dielectric Barrier Discharge)) form plasma when passed through a suitable dielectric (e.g., acne patches, dedicated films, etc.). Plasma is output in the form of a round or square area through a suitable dielectric, and this conventional method has a harmful effect on the user's body because the ozone emission amount exceeds the ozone human safety standard (0.05pppm). There is.

In addition, the treatment of certain areas with this type of cotton irradiation (for example, acne treatment) can provide strong ultraviolet radiation to the skin, which may help local areas (eg acne treatment), but there is a risk of developing skin cancer. Because it is applied to the stimulus to unnecessary places there is a disadvantage that affects the normal tissue does not have to manage.

Meanwhile, the head cap 105 is a cap for inserting and fixing a tip (or electrode) formed on the second substrate 133 or the second substrate 133 that performs the same operation as the tip. The head cap 105 may be referred to as an injection cap because it is injected from the mold, and may further be called a head cap including the bracket cap 130 and the guide bracket 132 of FIG. 2. In other words, the bracket cap 130, the guide bracket 132, and the head cap 105 may be regarded as fixing the second substrate 133 generating the ring plasma. Body case 100 corresponds to the frame forming the outer edge of the plasma skin care device 90 according to an embodiment of the present invention, but can be modified as much as possible, it will not be specifically limited to the above form.

The interface unit 110 includes user interface units 111, 115, and 117 for receiving a user command through an interface with the user, a display unit 113 for displaying an operation state of the device to the user, and the like. .

3 is a block diagram illustrating a driving unit of FIG. 2.

As shown in FIG. 3, the driving unit 120 of FIG. 2 according to the first embodiment of the present invention includes a part or all of the plasma processing unit 300, the control unit 310, and the interface unit 320.

Herein, "including some or all" means that some components such as the interface unit 320 are omitted so that the plasma skin care device 90 is configured, or some components such as the plasma processing unit 300 are similar to the control unit 310. Meaning that it can be configured in combination with other components, etc., will be described as including all to help a full understanding of the invention.

The plasma processing unit 300 generates and outputs a plasma from the outside using, for example, a high voltage provided from the controller 310. In addition, the plasma processing unit 300 converts the generated plasma, that is, the first plasma into a plurality of second plasmas. Here, the plurality of second plasmas refers to plasmas in which the first plasma is provided by a plurality of paths. In other words, the plurality of second plasmas is a modified state of the first plasma. For example, each second plasma may be controlled on and off and selectively output. This is because the production of a plurality of second plasma using a single first plasma is advantageous because it is advantageous in terms of manufacturing cost and the like, it may be possible to be formed in various other ways. In other words, it may be possible to convert each of the plurality of first plasmas into a plurality of second plasmas again. Therefore, in the exemplary embodiment of the present invention, the plasma processing unit 300 focuses more on how to induce the plasma to the user's skin through the plasma output unit rather than to produce the plasma.

For example, the plasma processor 300 may include a plasma generator 301 and a switching unit 303. Although not shown in the drawing, the plasma generator 301 may generate a plasma using a high voltage provided from the controller 310 or an externally provided voltage. The plasma generator 301 may generate an arc (ARC) plasma according to an embodiment of the present invention. Can include a transformer to produce. However, in the embodiment of the present invention, since the DBD method can be any number, the arc method will not be particularly limited. For example, if a plurality of lines can be irradiated, a dielectric suitable for the plasma generated by the arc discharge can be placed in front of the output to finally induce the plasma to the user's skin. The switching unit 303 may include a plurality of switching elements, and the plurality of switching elements may be connected in parallel to output terminals of the plasma generation unit 301, respectively. Through this, the plasma generated by the plasma generator 301 is divided through the plurality of switching elements and output through the plasma output unit. The switching device may include a device such as a transistor (TR) or a field effect transistor (FET). According to the exemplary embodiment of the present invention, the plurality of switching elements configuring the switching unit 303 may be divided into a plurality of groups and controlled, and a plurality of switching elements included in each group may also be controlled.

The controller 310 controls the overall operation of the plasma skin care device 110. In other words, when a user's request is made through the interface unit 320, the controller 310 controls the plasma generator 301 to generate a plasma according to, for example, an on operation of a power source. In addition, the controller 310 controls the plurality of switching elements constituting the switching unit 303 according to a specified operation pattern so that the plasma is guided to the skin of the user in a plurality of pre-irradiation methods. In this process, the controller 310 may control by controlling switching frequencies of the plurality of switching elements. That is, since the adjustment of the switching frequency corresponds to the adjustment of the operating frequency, the operating speed may be increased.

According to an embodiment of the present invention, the output of the plasma by the irradiation method is to reduce the ozone emission amount so as not to exceed the ozone human safety allowance standard, and the plurality of the irradiation methods are intended to increase the area actually affecting the skin. It can be seen that. On the contrary, even if the plasma output is large by a plurality of pre-irradiation methods, since the plasma can be induced only in a narrow area of the skin by controlling the switching unit 303, the user's use of the device may be more convenient. There will be. As such, the controller 310 may freely adjust the output amount of plasma through the control of the switching unit 303. Of course, the embodiment of the present invention is to control the switching unit 303 to control the switching amount 303, rather than adjusting the amount of output to achieve the same effect as when the surface irradiation by intersecting a plurality of pre-irradiation at a rapid cycle, but any one It will not be limited to the operation of.

As described above, when the control unit 310 guides the plasma to the skin in a large area and outputs the plasma, the controller 310 may not only concentrate on one part but also output the plasma, and may not be concentrated only on one part. The switching unit 303 may be controlled. For example, if it is determined that intensive treatment is necessary at an area such as acne, plasma may be output to the corresponding area. However, when acne is uniformly distributed in a large area, a plurality of switching elements constituting the switching unit 303 may be clockwise or The plasma may be output to the skin while being rotated counterclockwise, or the plasma may be output in various other ways. The controller 310 controls the switching unit 303 so that the plasma is not output from the tip (i.e., the second tip) of the tip (i.e., the second tip) from which the plasma is output. Alternately, or in the process of rotating between the adjacent groups in the clockwise, counterclockwise direction can be operated. As such various methods are possible, embodiments of the present invention will not be specifically limited to how the plasma is output to the skin. However, it is clear that the plasma is induced in the skin by a plurality of pre-radiation methods.

Although not actually included in the driver 120, the interface unit 320 performs an interface operation with a user. To this end, the interface unit 320 may include various types of buttons for receiving a user's command, but may also include a microphone and a voice recognizer for receiving and processing the command in the form of voice. The interface unit 320 may recognize the voice signal received through the microphone through a voice recognizer, interpret the command, and provide the interpreted command to the controller 310 in the form of digital information (0, 1). Then, the controller 310 interprets the received machine language and performs an operation matching the interpreted machine language. For example, when the user utters a command “operate in mode 3” through the interface unit 320, the controller 310 performs an operation matching the corresponding command.

4 is a circuit diagram illustrating the driving unit of FIG. 3.

As shown in FIG. 4, the driver 120 ′ according to another exemplary embodiment of the present invention includes a part or all of the plasma processor 400, the controller 410, and the plasma output unit 420, wherein “ "Include some or all" is synonymous with the foregoing.

First, the plasma processor 400 includes a plasma generator 401 and a switch 403. The plasma generator 401 includes a driving driver 401a and a plasma generator 401b, and the driving driver 401a drives the plasma generator 401b under the control of the controller 410. In other words, the plasma generator 401b has an output voltage value of, for example, 1KVpp, and the driving driver 401a may be involved in such an operation because a voltage formed at a specific frequency is output from the mid-frequency range of 30KHz to 100KHz. have. For this purpose, the driving driver 401a may include switching elements such as a FET.

The driving drivers 401a are electrically connected in parallel to each other, for example, each of the switching elements such as the FET is electrically connected to the primary coil of the transformer forming the plasma generator 401b as shown in FIG. 4. The capacitor (C) and the resistor (R) connected between each switching element and the primary coil may serve as a stabilizer for stably inputting the output voltage of the driving driver 401a to the primary side of the transformer. have. Both ends of the secondary coil of the transformer are connected to one side of the switching unit 403 and the ground, respectively. The turns ratio of the transformer can be determined at 500 or more and 3000 or less. The transformer may also include a dielectric between the primary and secondary coils.

According to this configuration, the driving driver 401a is controlled by the controller 410, and stably provides a high voltage of a level designated as the primary coil of the transformer. For example, according to an embodiment of the present invention, the plasma waveform of the voltage induced in the secondary coil of the transformer has an output voltage value of 1 KVpp or more, and has a frequency of 30 Hz or more and 100 Hz or less, that is, a frequency of 40 Hz among medium frequencies Depending on the output voltage value determined based on this, the above turns ratio can be sufficiently inferred. The above medium frequency range, in particular 40 kHz, can improve the absorption rate of wrinkle improvement components such as oligonucleotides, and thus may be more effective than skin lifting devices in which a conventional lifting function is implemented.

The plasma generator 401b includes a transformer. Since high voltage is needed to generate arc-type plasma, high voltage is generated through a transformer. In this case, the winding ratio may be determined in a range of 500 or more and 3000 or less. Under the control of the driving driver 401a, the voltage provided to the primary coil of the transformer is induced to the secondary coil so that the arc discharge is performed to the skin of the user through the plasma output unit 420. In other words, the voltage applied to the primary coil of the transformer is boosted according to the turns ratio with the secondary coil to generate a plasma by an insulator or dielectric formed between the secondary coil and the generated plasma is the secondary coil. Since the plasma output unit 420 is electrically connected directly or indirectly to the user's skin or is grounded, the plasma generated in the same manner as the electrical discharge (ARC) can be output to the skin. Of course, the plasma output unit 420 according to an embodiment of the present invention may further include an auxiliary device such as a film, a patch, etc. for efficiently inducing plasma to the skin for driving the DBD method. In other words, a method suitable for outputting the final plasma may be possible by placing a dielectric suitable for the plasma generated through the arc discharge in front of the output. As the dielectric, for example, an acne patch, a dedicated film, or the like may be used, wherein the dedicated film may be a polyimide or Teflon material having a thickness of 0.1 to 0.3 mm. This is well illustrated in FIG. 5.

The switching unit 403 may include a first switching unit to an Nth switching unit. Each switching unit includes a plurality of switching elements, and the plurality of switching elements constituting each switching unit are respectively connected to the first to Nth groups of the plasma output unit 420. Through this, the switching unit 403 controls each of the plurality of tips of the plasma output unit 420 divided into a plurality of groups. For example, the switching unit 403 may control the first to Nth switching units as a whole to control the first to Nth plasma output units under the control of the control unit 410. For example, the plurality of switching units of the first switching unit may be used. By controlling the device, the plasma output to each tip of the first plasma output unit matched thereto may be controlled. For example, the first plasma output unit outputs the plasma through the two tips, the second plasma output unit outputs the plasma through the three tips, or the first plasma output unit outputs the plasma through the two tips, and the second The plasma output unit may cause the plasma to be output while rotating clockwise at all tips. As described above, various operation methods are possible, and the controller 410 may operate such an operation according to a predetermined method by programming. And the behavior can be set by various experiments to the last, examples will be discussed later.

The controller 410 controls the overall operation of the plasma skin care device 90. In this regard, since it has been sufficiently described in the control unit 310 of FIG. In addition, although the control unit 310 of FIG. 3 is the same, the control unit 410 may include a CPU and a memory. The memory includes a RAM or a ROM, and stores a program related to controlling the switching unit 403, and executes the program under the control of the CPU. The CPU may include, for example, an operation circuit (ALU) and a control circuit as a microprocessor, that is, a microcomputer, and may further include an instruction interpreter or a register group. Since this is obvious to those skilled in the art, a description thereof is omitted for convenience.

Although the plasma output unit 420 may be formed integrally with the plasma skin care device 90, the plasma output unit 420 may be formed to be easily attached or detached according to an embodiment of the present invention. The plasma output unit 420 may include a plurality of plasma output units 420, and the plurality of plasma output units 420 may not only have different shapes, but also different operations. In other words, if the first plasma output unit (eg, the first group) performs ring-shaped line irradiation, the second plasma output unit may perform square-line irradiation, and the body of the first plasma output unit may be used. In other words, although the shape is square, the second plasma output unit forms a circle, or the first plasma output unit outputs the plasma by a plurality of pre-radiation methods, but the second plasma output unit alternates the plasma by one pre-radiation method. Since various shapes and various operations are possible, such as to be output, the embodiment of the present invention will not be limited to any one form and method. However, it is clear that the plasma output unit 420 operates in conjunction with the switching unit 403 operating under the control of the control unit 410.

To treat acne, you should basically: 1) reduce the secretion of sebum, 2) prevent keratin from thickening, and 3) reduce the number of acne bacteria in the hair follicles that cause acne, and 4) prevent inflammation of the acne. Of these, the above 3) and 4) can be managed using plasma, and by using plasma technology, it will be possible to effectively manage acne by concentrating radicals and ultraviolet rays on the topical areas.

5 to 8 are views showing various modifications of the plasma output unit according to an embodiment of the present invention.

5 to 8 together with FIG. 1 for convenience of description, the plasma skin care apparatus 90 according to the embodiment of the present invention includes a body (or body, frame) 500 including a tip as shown in FIG. 5. A plurality of tips 500a are formed to induce and output a plurality of ring-shaped plasmas to one surface of the user's skin. The plurality of tips 500a form an array and have a matrix structure, for example. For example, the plurality of tips 500a may be formed to have an irregular matrix plasma structure as shown in FIG. 5. 5 illustrates a plasma tip (or output unit) for generating plasma in a DBD method using a dedicated film, but the embodiment of the present invention is not particularly limited to the DBD method.

The plasma output unit 420 of FIG. 4 may have a circular shape as shown in FIG. 5. The plasma output unit 420 includes a plurality of ring-shaped tips 500a capable of ring-shaped line irradiation, and the plurality of tips 500a may be divided into a plurality of groups in one frame and operate. By controlling the plurality of tips 500a constituting each group, the plasma 500b may be guided to the skin of the user and output. In FIG. 5, the entirety of the plurality of tips 500a is not simultaneously operated, but is partially changed and illustrated.

In addition, the plasma skin care apparatus 90 according to the embodiment of the present invention may have any shape that includes a plurality of tips 600a as shown in FIG. Such appearance may be appropriately selected depending on which part of the body to use mainly. 6 shows that the plasma output unit 420 of FIG. 4 has a non-circular shape and the plurality of tips 600a may be formed to have a regular matrix plasma structure.

As described above, the plasma output unit 420 of FIG. 4 may have a circular or non-circular shape, and the plurality of tips 500a and 600a outputting the ring-shaped plasmas 500b and 600b may be matrix plasma structures. You can have a regular array or an array with no rules. In more detail, the output unit 420 may be configured by the plurality of tips 500a and 600a of the matrix structure by freely positioning the plurality of tips 500a and 600a in a two-dimensional planar structure composed of x and y axes. . Furthermore, by extending the three-dimensional matrix structure, it is possible to control the physical distance from the area to be treated, so that the effective plasma can be output even in a curved area.

Furthermore, the plasma output unit 420 of FIG. 4 according to an embodiment of the present invention reduces the size of the tip, more precisely, the upper ring portion of the tip, and arranges one or more tips in a matrix structure to actually affect the skin. The state can further expand the area. 7 shows that the plasma output unit 420, that is, the body is circular, and the plasma output portion of the tip 700a is formed in a square shape, so that the plasma 700b can be induced to the skin in a rectangular linear irradiation method. Is showing. For example, as shown in FIG. 7, each of the seven circular circular plasma output units 420 may output the plasma 700b at a fast cycle in a clockwise order or in a different order pattern. will be.

In fact, the area affecting the skin is large, but because it is a ray irradiation method, the amount of ozone emitted is small, and by controlling a plurality of (ring-shaped) tips 700a, it may be possible to further refine the desired part by precise treatment.

The plasma output unit 420 including the ring-shaped tip 700a may not only be detachable from the main body, but also may adjust the size of the area that affects the size and extent of the treatment site.

Furthermore, the plasma output is reduced to reduce the inner area of the line of the plasma output unit 420 including the ring-shaped tip 700a and to maintain the size of the entire plasma output unit 420 when the tips 700a are arranged in a matrix structure. It may be possible to reduce the diameter and increase the number to the extent that it is not represented in the visual plane. At this time, the number may be determined in consideration of the area of the area to be treated. The ring-shaped tip 700a may have a different shape as shown in FIG. 7, which is not circular, and may vary depending on the number and arrangement of the ring-shaped tips 700a.

Furthermore, the plasma output unit 420 of FIG. 4 according to an embodiment of the present invention may be configured of the first plasma output unit 800 and the second plasma output unit 810 having different matrix (or array) structures. It may be. In addition, the first plasma output unit 800 and the second plasma output unit 810 may be different from each other in the operation method thereof.

The tips 800a and 810a including the respective ring shapes may output the plasmas 800b and 810b one by one or in a constant pattern at a rapid cycle. At this time, the neighboring rows or columns are not output at the same time to reduce the ozone emission amount. As shown in FIG. 8, a plurality of outputs at the same time, the pattern may be changed. At this time, if a group of ring-shaped tips 800a and 810a located at a particular row and column that are turned on at the same time is referred to as a group, the groups output plasmas 800b and 810b at a rapid cycle, and thus the plasma effect that appears on the skin is determined by While the therapeutic effect of the plasmas 800b and 810b can be shown in a large area such as turning on the tips 800a and 810a simultaneously, the number of tips 800a and 810a which are simultaneously turned on at the same time is small and is not represented as non-neighborhood. Because of this, ozone emissions will be significantly lower.

9 is a flowchart illustrating a driving process of the plasma skin care apparatus according to the embodiment of the present invention.

For convenience of description, referring to FIG. 9 together with FIG. 1, the plasma skin care apparatus 90 according to an embodiment of the present invention generates a first plasma based on a user's request, and generates a plurality of second plasmas. Convert to plasma (S900). Here, the plurality of second plasmas may be regarded as plasmas selectively outputted such that the first plasmas are simultaneously provided in a plurality of paths and driven on / off.

In addition, the plasma skin care device 90 controls the plurality of converted second plasmas to be selectively output through the plasma output unit (S910). Here, "selectively output" means that the output of the plasma is most simply on and off controlled. In other words, it includes the simplest control operation such as outputting the plasma, blocking the output again. However, in the embodiment of the present invention to control the output of the plasma in a variety of control schemes beyond just this operation, which is because the control operation can be preset based on the data obtained by the experiment, in the embodiment of the present invention It will not be specifically limited to either operation.
