[0002] Skin management devices used to remove wrinkles, restore skin elasticity, and remove sebum typically include those that transmit ultrasound to the skin tissue (HIFU type), those that transmit high frequency to the skin tissue (RF type), and those that irradiate the skin tissue with laser (Optical type).

[0003] A device that delivers high frequencies to skin tissue repeatedly penetrates the deep layers of the skin (the dermis, for example, the face) by moving RF needle electrodes back and forth in a vertical direction. It uses the heat generated by the high frequency to remove damaged collagen and elastin fibers in the deep layers of the skin at the target location, thereby promoting the formation of new collagen and elastin fibers.

[0004] Furthermore, this skin management device improves skin pigmentation, acne scars, and wrinkles.

[0005] That is, after applying various energies to the target area of ​​the skin and intentionally inducing a wound, the skin regenerates by stimulating collagen in the dermis.

[0006] However, existing skin management devices are unable to deliver sufficient or efficient electrical energy to specific depths of the skin.

[0007] Therefore, existing skin management devices have low accuracy when performing ultrasound irradiation because they cannot accurately deliver sufficient or efficient electrical energy.

[0046] The working principle and embodiments of this disclosure will be described below with reference to the accompanying drawings.

[0047] The disclosed monopolar and bipolar current application devices at skin depth during needle insertion are used to raise the temperature of a target site below the skin surface that is electromagnetically energized via a microneedle to the level of heated tissue.

[0048] In this specification, the control unit of the monopolar and bipolar current application device for repeatedly inserting needles according to this disclosure includes all kinds of devices capable of performing computational processing and providing the results to the user. For example, the control unit of the monopolar and bipolar current application device for repeatedly inserting needles according to this disclosure may include all kinds of computers, server equipment, and portable terminals, or a combination thereof.

[0052] The monopolar and bipolar current application device according to this disclosure, which performs repeated needle insertion operations based on skin depth, can control the energy supply unit to apply a monopolar first high-frequency current and a bipolar second high-frequency current to the multiple electrodes respectively at current intensities corresponding to the different target depths reached, when multiple electrodes reach different target depths through repeated insertion and withdrawal operations. Furthermore, it controls the drug injection unit to inject drugs into the different target depths. In this case, the intensity of the monopolar first high-frequency current and the bipolar second high-frequency current can increase with increasing target depth, and their intensities can be different from each other.

[0053] The following details the monopolar and bipolar current application devices that apply current according to skin depth for performing repeated needle insertion operations.

[0054] Figure 1 This is a diagram illustrating the configuration of a monopolar and bipolar current application device for performing repeated needle insertion operations according to the present disclosure at skin depth. Figure 2 It will be by means of Figure 1 The process of moving the transfer unit to repeatedly perform insertion and extraction operations on multiple electrodes at the same position is illustrated in the figure as an example.

[0055] Figure 3 It is shown that the arrangement is in Figure 1 A diagram showing the structure of multiple needle-shaped electrodes in the electrode section. Figure 4 It is to Figure 3 The process of applying a unipolar first high-frequency current to multiple needle-shaped electrodes is illustrated as an example in the figure. Figure 5 It is to Figure 3 The process of applying a bipolar second high-frequency current to multiple needle-shaped electrodes is illustrated as an example in the figure.

[0056] Reference Figures 1 to 5 The monopolar and bipolar current application device 100 for performing repeated needle insertion operations according to skin depth may include an input unit 110, an electrode unit 120, an energy supply unit 130, a transfer unit 140, and a control unit 150.

[0057] The input unit 110 is used to receive target depth information within the user's skin. If the target depth information within the skin is received, the control unit 150 can control the operation of the device in accordance with the received target depth information within the skin. The target depth information within the skin can be a target depth value within the dermis.

[0058] This input unit 110 may include hardware physical keys (e.g., buttons, dome switches, scroll wheels, joysticks, etc. located on at least one of the front, back, and sides of the device) and software touch keys. As an example, touch keys may be configured as virtual keys, soft keys, or visual keys displayed on a touchscreen-type display via software processing, or as touch keys located outside the touchscreen. Furthermore, virtual keys or visual keys can be displayed on the touchscreen simultaneously in multiple forms; for example, they may be composed of graphics, text, icons, videos, or combinations thereof.

[0059] The electrode section 120 may include a plurality of needle-shaped electrodes 121 that are repeatedly inserted and withdrawn within the skin S. The plurality of needle-shaped electrodes 121 penetrate the deep layer of the skin S (for example, the dermis) by repeated insertion, and utilize high-frequency generated heat to remove damaged collagen and elastin fibers in the deep layer of the skin at the target location, thereby promoting the formation of new collagen and elastin fibers.

[0060] like Figure 3 As shown, in the electrode section 120, multiple needle-shaped electrodes 121 of various polarities, including multiple (+) polarity electrodes 121a and multiple (-) polarity electrodes 121b, can be arranged in multiple groups, and the multiple (-) polarity electrodes 121b and multiple (+) polarity electrodes 121a can be arranged in multiple groups. For example, multiple (+) polarity electrodes 121a and multiple (-) polarity electrodes 121b, arranged as multiple groups, can be repeatedly arranged in the odd-numbered columns of the electrode section 120, and multiple (-) polarity electrodes 121b and multiple (+) polarity electrodes 121a, arranged as multiple groups, can be repeatedly arranged in the even-numbered columns of the electrode section 120.

[0061] The power supply unit 130 can selectively apply a unipolar first high-frequency current and a bipolar second high-frequency current to a plurality of electrodes 121. The power supply unit 130 may include a switching circuit for selectively applying the unipolar first high-frequency current and the bipolar second high-frequency current.

[0062] At this time, as Figure 4As shown, the energy supply unit 130 can apply a unipolar first high-frequency current to the (+) polarity of the plurality of electrodes 121a and the (-) polarity of the loop pad 122. A current loop needs to be formed to allow the high-frequency current to flow through the skin S. When the energy supply unit 130 applies the unipolar first high-frequency current to the (+) polarity of the plurality of electrodes 121a and the (-) polarity of the loop pad 122, since the high-frequency energy is concentrated on the (+) polarity of the plurality of electrodes 121a, deeper heat transfer than bipolar heat transfer can be achieved, thereby generating abundant deep heat. The loop pad 122 can be a grounding pad.

[0063] And, as Figure 5 As shown, the energy supply unit 130 can apply a bipolar second high-frequency current to the (+) polarity of the plurality of electrodes 121a and the (-) polarity of the plurality of electrodes 121. When the energy supply unit 130 applies the bipolar second high-frequency current to the (+) polarity of the plurality of electrodes 121a and the (-) polarity of the plurality of electrodes 121b, since a current loop is formed between the (+) polarity of the plurality of electrodes 121a and the (-) polarity of the plurality of electrodes 121b, excessive heat transfer can be prevented, thereby concentrating the selected high-frequency irradiation area.

[0064] The transfer unit 140 can move the electrode unit 120 so that multiple electrodes 121 are delivered to the skin at different target depths by repeatedly performing insertion and withdrawal operations at the same position. At this time, the transfer unit 140 can move the electrode unit 120 in the vertical direction.

[0065] The control unit 150 may include: a memory 151 storing algorithms for controlling the operation of components within the device or data for a program of reproducing algorithms; and at least one processor 152, which performs the aforementioned operations using the data stored in the memory 151. The memory 151 and the processor 152 may be implemented using separate chips. Alternatively, the memory 151 and the processor 152 may be implemented using a single chip.

[0066] The memory 151 can store data supporting various functions of the device and programs for the operation of the control unit. It can store input / output data and multiple application programs (or applications) driven by the device, as well as data and commands for the operation of the device. At least some of these applications can be downloaded from an external server via wireless communication.

[0067] Such a memory 151 may include at least one type of storage medium selected from flash memory, hard disk, solid-state disk, silicon disk drive, multimedia card micro, card memory (such as SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic storage, magnetic disk, and optical disk. Furthermore, the memory 151 may be separate from this device, but may also be a database connected via wired or wireless means.

[0068] The memory 151 can store depth information of the skin layer and data related to the repeated needle insertion operation. The processor 152 can control the operations related to the repeated needle insertion operation.

[0069] When the multiple electrodes 121 reach different target depths in the skin layer through repeated insertion and withdrawal operations, the processor 152 controls the energy supply unit 130 to apply a unipolar first high-frequency current and a bipolar second high-frequency current to the multiple electrodes 121 with current intensities corresponding to the different target depths reached. In this case, the intensity of the unipolar first high-frequency current and the bipolar second high-frequency current can increase with increasing target depth, and their intensities can differ from each other. For example, the intensity of the first high-frequency current can be greater or less than the intensity of the second high-frequency current as the target depth increases.

[0070] If the plurality of electrodes 121 perform an insertion operation for the first time, and the target depth is a preset first depth, the processor 152 can control the power supply unit 130 to apply a first high-frequency current to the plurality of electrodes 121 at a current intensity corresponding to the first depth. Furthermore, if the plurality of electrodes 121 perform an insertion operation for the second time, and the target depth is a second depth deeper than the preset first depth, the processor 152 can control the power supply unit 130 to apply a second high-frequency current to the plurality of electrodes 121 at a current intensity corresponding to the second depth. Furthermore, if the plurality of electrodes 121 perform an insertion operation for the third time, and the target depth is a third depth deeper than the preset second depth, the processor 152 can control the power supply unit 130 to apply a first high-frequency current to the plurality of electrodes 121 at a current intensity corresponding to the third depth.

[0071] If the plurality of electrodes 121 perform an insertion operation for the first time, and the target depth is a preset first depth, the processor 152 can control the power supply unit 130 to apply a second high-frequency current to the plurality of electrodes 121 at a current intensity corresponding to the first depth. Furthermore, if the plurality of electrodes 121 perform an insertion operation for the second time, and the target depth is a second depth deeper than the preset first depth, the processor 152 can control the power supply unit 130 to apply a first high-frequency current to the plurality of electrodes 121 at a current intensity corresponding to the second depth. Furthermore, if the plurality of electrodes 121 perform an insertion operation for the third time, and the target depth is a third depth deeper than the preset second depth, the processor 152 can control the power supply unit 130 to apply a second high-frequency current to the plurality of electrodes 121 at a current intensity corresponding to the third depth.

[0072] The processor 152 can control the drug delivery unit 160 to inject drugs for skin management into different target depths of the skin layer when multiple electrodes 121 reach different target depths of the skin layer by repeatedly performing insertion and withdrawal operations.

[0073] Furthermore, whenever multiple electrodes 121 are inserted according to the skin layer insertion depth, the processor 152 can control the display device to monitor the multiple electrodes 121 inserted according to the insertion depth. Also, whenever multiple electrodes 121 are inserted according to the skin layer insertion depth, the processor 152 can measure the impedance to each current according to the insertion depth, and adjust and calibrate the energy according to the insertion depth based on the measured impedance.

[0074] Figure 6 This is a flowchart illustrating a method for applying monopolar and bipolar currents at skin depth to perform repeated needle insertion operations according to the present disclosure.

[0075] Reference Figure 6The method for applying monopolar and bipolar currents according to skin depth to perform repeated needle insertion operations may include an input step (S610), a movement step (S620), a judgment step (S630), and a control step (S640).

[0076] The input unit 110 can receive target depth information within the user's skin (S610). This target depth information within the skin can be a target depth value within the dermis (S610).

[0077] The transfer unit 140 can move the electrode unit 120 so that multiple electrodes 121 reach the skin S at different target depths by repeatedly performing insertion and withdrawal operations at the same position (S620). The processor 152 can control the transfer unit 140 to move the electrode unit 120 based on the target depth information within the skin S input through the input unit 110, so that multiple electrodes 121 reach the skin S at different target depths by repeatedly performing insertion and withdrawal operations at the same position. At this time, the multiple electrodes 121 can penetrate to their respective target depths within the dermis.

[0078] The processor 152 can determine whether the multiple electrodes 121 have reached different target depths by repeatedly performing insertion and withdrawal operations (S630). For example, the processor 152 can determine whether the multiple electrodes 121 have reached each target depth within the dermis.

[0079] When the multiple electrodes 121 reach different target depths by repeatedly performing insertion and withdrawal operations (S630), the processor 152 controls the energy supply unit 130 to apply a unipolar first high-frequency current and a bipolar second high-frequency current to the multiple electrodes 121 respectively with current intensities corresponding to the different target depths reached, and controls the drug injection unit 160 to inject the drug for skin management into the different target depths (S640). The energy supply unit 130 can selectively apply the unipolar first high-frequency current and the bipolar second high-frequency current to the multiple electrodes 121.

[0080] At this point, the intensity of the unipolar first high-frequency current and the bipolar second high-frequency current can increase with increasing target depth, and their intensities differ from each other. Furthermore, the drug injection unit 160 can inject drugs for skin management into each target depth within the dermis. For example, as the target depth increases, the intensity of the unipolar first high-frequency current can be greater than the intensity of the bipolar second high-frequency current. That is, throughout the entire time it takes for the multiple electrodes 121 to reach the target depth within the dermis, the intensity of the unipolar first high-frequency current can be greater than the intensity of the bipolar second high-frequency current. As another example, as the target depth increases, the intensity of the bipolar second high-frequency current can be greater than the intensity of the unipolar first high-frequency current. That is, throughout the entire time it takes for the multiple electrodes 121 to reach the target depth within the dermis, the intensity of the bipolar second high-frequency current can be greater than the intensity of the unipolar first high-frequency current.

[0081] Figures 7 to 10 It will be Figure 6 The control steps in which the first high-frequency current, the second high-frequency current, and the process of applying the first high-frequency current to multiple electrodes through each insertion operation are illustrated in the figure as an example.

[0082] Reference Figures 7 to 10 After the first insertion operation of the plurality of electrodes 121, the processor 152 can determine whether the target depth is a preset first depth TH1 (S641a). If the target depth within the dermis S1 is the preset first depth TH1 (S641a), the processor 152 can control the energy supply unit 130 to apply a unipolar first high-frequency current to the plurality of electrodes 121 with a current intensity corresponding to the first depth TH1 (S642a). At this time, S2 can be the stratum corneum, S3 can be the epidermis, and S4 can be the subcutaneous tissue layer. Furthermore, the processor 152 can control the drug injection unit 160 to inject a drug for skin management into the first depth TH1 within the dermis (S642a).

[0083] After the second insertion operation is performed on the multiple electrodes 121, the processor 152 can determine whether the target depth is a second depth TH2 that is deeper than the preset first depth TH1 (S643a). If the target depth within the dermis S1 is the preset second depth TH2 (S643a), the processor 152 can control the energy supply unit 130 to apply a bipolar second high-frequency current to the multiple electrodes 121 with a current intensity corresponding to the second depth TH2 (S644a). Furthermore, the processor 152 can control the drug injection unit 160 to inject a drug for skin management into the second depth TH2 within the dermis (S644a). At this time, the amount of drug injected into the second depth TH2 can be less or more than the amount of drug injected into the first depth TH1.

[0084] Furthermore, after the second insertion operation of the multiple electrodes 121, when the target depth reaches a preset second depth TH2, the processor 152 can control a preset first rest interval between the application times of the monopolar first high-frequency current and the bipolar second high-frequency current. This first rest interval is the period during which the bipolar second high-frequency current is not applied. By including this first rest interval, this disclosure can prevent skin burns in advance while maximizing the optimal skin improvement effects of both monopolar and bipolar currents.

[0085] After the third insertion operation is performed on the multiple electrodes 121, the processor 152 can determine whether the target depth is a third depth TH3, which is deeper than the preset second depth TH2 (S645a). If the target depth in the dermis S1 is the preset third depth TH3 (S645a), the processor 152 can control the energy supply unit 130 to apply a unipolar first high-frequency current to the multiple electrodes 121 with a current intensity corresponding to the third depth TH3 (S646a). At this time, the amount of drug injected into the third depth TH3 can be less or more than the amount of drug injected into the second depth TH2.

[0086] Furthermore, after the third insertion operation of the multiple electrodes 121, when the target depth reaches a preset third depth TH3, the processor 152 can control a preset second rest interval between the application times of the bipolar second high-frequency current and the unipolar first high-frequency current. This second rest interval is a period during which the unipolar first high-frequency current is not applied. By including this second rest interval, this disclosure can prevent skin burns in advance while maximizing the optimal skin improvement effects of both the unipolar and bipolar methods.

[0087] Figures 11 to 14 It will be Figure 6 The control steps involve controlling the application of a second high-frequency current, a first high-frequency current, and a second high-frequency current to multiple electrodes through each insertion operation, as illustrated in the figure below.

[0088] Reference Figures 11 to 14After the first insertion operation of the plurality of electrodes 121, the processor 152 can determine whether the target depth is a preset first depth TH1 (S641b). If the target depth within the dermis S1 is the preset first depth TH1 (S641b), the processor 152 can control the energy supply unit 130 to apply a bipolar second high-frequency current to the plurality of electrodes 121 with a current intensity corresponding to the first depth TH1 (S642b). At this time, S2 can be the stratum corneum, S3 can be the epidermis, and S4 can be the subcutaneous tissue layer. Furthermore, the control step (S642b) can be performed by the processor 152 to control the drug injection unit 160 to inject a drug for skin management into the first depth TH1 within the dermis.

[0089] After the second insertion operation is performed on the multiple electrodes 121, the processor 152 can determine whether the target depth is a second depth deeper than the preset first depth TH1 (S643b). If the target depth within the dermis S1 is the preset second depth TH2 (S643b), the processor 152 can control the energy supply unit 130 to apply a unipolar first high-frequency current to the multiple electrodes 121 with a current intensity corresponding to the second depth TH2 (S644a). Furthermore, the processor 152 can control the drug injection unit 160 to inject a drug for skin management into the second depth TH2 within the dermis (S644b). At this time, the amount of drug injected into the second depth TH2 can be less or more than the amount of drug injected into the first depth TH1.

[0090] Furthermore, after the second insertion operation of the multiple electrodes 121, when the target depth reaches a preset second depth TH2, the processor 152 can control a preset third rest interval between the application time points of the bipolar second high-frequency current and the unipolar first high-frequency current. This third rest interval is a period during which the unipolar first high-frequency current is not applied. By including this third rest interval, this disclosure can prevent skin burns in advance while maximizing the optimal skin improvement effects of both the unipolar and bipolar methods.

[0091] After the third insertion operation is performed on the multiple electrodes 121, the processor 152 can determine whether the target depth is a third depth TH3, which is deeper than the preset second depth TH2 (S645b). If the target depth within the dermal layer S1 is the preset third depth TH3 (S645b), the processor 152 can control the energy supply unit 130 to apply a bipolar second high-frequency current to the multiple electrodes 121 with a current intensity corresponding to the third depth TH3 (S646b). At this time, the amount of drug injected into the third depth TH3 can be less or more than the amount of drug injected into the second depth TH2.

[0092] Furthermore, after the third insertion operation of the multiple electrodes 121, when the target depth reaches a preset third depth TH3, the processor 152 can control a preset fourth rest interval between the application times of the first high-frequency current of the monopolar type and the second high-frequency current of the bipolar type. This fourth rest interval is a period during which the second high-frequency current of the bipolar type is not applied. By including this fourth rest interval, this disclosure can prevent skin burns in advance while maximizing the optimal skin improvement effects of both monopolar and bipolar types.
