Description

Hybrid needle cartridge type skin care device

[0001] The present invention relates to a hybrid needle cartridge type skin care device that can apply high-intensity high-frequency energy to the deep skin through a surface electrode and needle of a cartridge without affecting changes in the characteristics of the drug when injecting the drug into the deep skin through the cartridge.

[0002] In general, skin care devices for removing wrinkles, restoring skin elasticity, and removing sebum include those that deliver HIFU energy to skin tissue (HIFU type), those that deliver high-frequency energy to skin tissue (RF type), and those that irradiate laser light to skin tissue (Optical type).

[0003] A device that delivers high frequency to skin tissue repeatedly penetrates the deep part of the skin (e.g., the dermal layer) of the skin (e.g., the face) with an RF needle electrode (i.e., a needle for applying high frequency energy) that moves back and forth in a vertical direction, and uses the heat generated by the high frequency to remove damaged collagen, elastic fibers, etc. from the deep part of the skin at the target point and promote new formation.

[0004] Furthermore, these skin care devices improve skin pigmentation, acne scars, and wrinkles. They intentionally induce wounds by applying various energies to targeted areas of the skin, stimulating collagen in the dermis and inducing collagen regeneration, thereby regenerating the skin.

[0005] However, conventional skin care devices were unable to deliver abundant or efficient electrical energy to a specific depth of the skin.

[0006] Therefore, conventional skin care devices, when performing a procedure, cannot accurately irradiate abundant electric energy or efficient electric energy, resulting in low accuracy of the procedure. In order to supplement the skin care effect, a method of injecting a medicinal solution is being additionally studied. However, there is still a problem that the skin care efficiency is not high due to insufficient technology for preventing changes (changes) in the characteristics of the medicinal solution due to electric energy irradiation (or high-frequency energy application).

[0007] Therefore, there is a need for a technology that minimizes the mutual influence between electrical energy irradiation (or high-frequency energy application) and liquid injection during skin care and increases the effectiveness of skin care.

[0008] According to one aspect of the present invention, the present invention was created to solve the above problems, and the purpose is to provide a hybrid needle cartridge type skin care device that can apply high-intensity high-frequency energy to the deep skin through the surface electrode and needle of the cartridge without affecting the change in the characteristics of the drug when injecting the drug into the deep skin through the cartridge.

[0009] A hybrid needle cartridge type skin care device according to one aspect of the present invention is characterized by comprising: a hybrid needle cartridge including a liquid needle and an RF needle; a hybrid needle cartridge surface electrode formed on a surface of the hybrid needle cartridge; a high-frequency module for applying high-frequency energy to a deep part of the skin through at least one of the liquid needle and the RF needle penetrated into a deep part of the skin and the hybrid needle cartridge surface electrode; and a processor for setting polarities of the liquid needle and the RF needle and the hybrid needle cartridge surface electrode, and controlling the high-frequency module to apply current to the liquid needle, the RF needle, and the hybrid needle cartridge surface electrode, thereby applying high-frequency energy to the deep part of the skin.

[0010] In the present invention, the processor is characterized in that it sequentially controls the skin invasion timing of the liquid needle and the RF needle and the insertion timing of the liquid needle according to the hybrid needle cartridge control mode.

[0011] In the present invention, in order to alleviate pain felt by the subject due to needle invasion, the present invention further comprises a cartridge vibration module that vibrates the hybrid needle cartridge in an electric manner when the hybrid needle cartridge comes into contact with the skin before the drug needle and RF needle are invasive into the skin.

[0012] In the present invention, in order to alleviate pain felt by the subject due to needle invasion, before the drug needle and RF needle are invasive into the skin, when the hybrid needle cartridge comes into contact with the skin, a suction module is further included that suctions and pulls the skin in a negative pressure manner through a suction groove formed at the edge of the skin contact area of ​​the hybrid needle cartridge.

[0013] In the present invention, the processor is characterized in that it electrically controls the drug needle and RF needle of the hybrid needle cartridge to control the drug injection depth and the transmission depth of high-frequency energy.

[0014] In the present invention, the processor is characterized in that it is implemented so that the surface electrode of the hybrid needle cartridge can be set as a positive electrode (+) and each needle tip can be set as a negative electrode (-), or the surface electrode of the hybrid needle cartridge can be set as a negative electrode (-) and each needle tip can be set as a positive electrode (+).

[0015] In the present invention, the hybrid needle cartridge surface electrode is formed using an insulating film, and the insulating film is characterized in that an electrode or circuit can be printed or an electronic component can be attached by designating an area, and some areas are formed to be transparent or translucent.

[0016] In the present invention, the processor is characterized in that, when the hybrid needle cartridge comes into contact with the skin, the processor vibrates the hybrid needle cartridge through a cartridge vibration module, intrudes each needle into a deep part of the skin according to a preset protrusion length, detects skin impedance in a skin contact state before intruding each needle into the skin, or in a skin contact state after intruding each needle into the skin, and, when the skin impedance is detected, applies high-frequency energy of an intensity corresponding to a final high-frequency energy setting value calculated by reflecting a high-frequency energy correction value corresponding to the skin impedance value to a preset high-frequency energy setting value to the human body.

[0017] In the present invention, the processor is characterized in that, when the hybrid needle cartridge comes into contact with the skin, the processor vibrates the hybrid needle cartridge through a cartridge vibration module, intrudes each needle deep into the skin according to a preset protrusion length, detects skin impedance in a skin contact state before intruding each needle into the skin, or in a skin contact state after intruding each needle into the skin, and when the skin impedance is detected, the processor corrects the protrusion length of each needle corresponding to the skin thickness based on a skin thickness lookup table compared to a preset skin impedance, and automatically adjusts the protrusion length of each needle in an electric manner according to the corrected protrusion length of each needle.

[0018] In the present invention, when the first hybrid needle cartridge control mode is set, the processor vibrates the hybrid needle cartridge through a cartridge vibration module when the hybrid needle cartridge comes into contact with the skin, sucks and pulls the skin in contact with the hybrid needle cartridge through a suction module, protrudes the drug needle and the RF needle from the hybrid needle cartridge to infiltrate the skin, injects the drug through the drug needle, and then retracts only the drug needle back into the hybrid needle cartridge, sets the RF needle to one of the positive / negative electrodes (+, -), and sets the surface electrode of the hybrid needle cartridge to one of the negative / positive electrodes (-, +) as a corresponding electrode to apply high-frequency energy.

[0019] In the present invention, the processor is characterized in that, when the hybrid needle cartridge comes into contact with the skin, the hybrid needle cartridge vibrates through a cartridge vibration module, the skin in contact with the hybrid needle cartridge is sucked and pulled through a suction module, the drug needle and the RF needle are protruded from the hybrid needle cartridge to infiltrate the skin, and the drug is injected through the drug needle, and when the drug injection is completed, both the drug needle and the RF needle are set to one of the positive / negative electrodes (+, -) without the drug needle being inserted, and the surface electrode of the hybrid needle cartridge is set to one of the negative / positive electrodes (-, +) as a corresponding electrode to apply high-frequency energy.

[0020] According to one aspect of the present invention, the present invention enables high-intensity high-frequency energy to be applied to the deep skin through a surface electrode and a needle of the cartridge without affecting changes in the characteristics of the drug when the drug is injected into the deep skin through the cartridge, and improves the efficiency of energy use for skin care by adjusting the needle length or energy intensity appropriate to the skin thickness or skin condition.

[0028] Hereinafter, a hybrid needle cartridge type skincare device according to one embodiment of the present invention will be described with reference to the attached drawings. In this process, the thickness of lines and the sizes of components depicted in the drawings may be exaggerated for clarity and convenience. Furthermore, the terms described below are defined based on their functions in the present invention and may vary depending on the intentions or practices of the user or operator. Therefore, the definitions of these terms should be based on the contents throughout this specification.

[0029]

[0030] FIG. 1 is an exemplary diagram showing a schematic configuration of a hybrid needle cartridge type skin care device according to one embodiment of the present invention.

[0031] As illustrated in FIG. 1, the hybrid needle cartridge type skin care device according to the present embodiment includes a skin impedance detection module (110), a processor (120), a hybrid needle cartridge (130), a cartridge vibration module (140), and a suction module (150).

[0032] The skin impedance detection module (110) detects the impedance of the skin in contact when the hybrid needle cartridge (130) is driven.

[0033] For reference, skin impedance varies depending on the area, skin condition, amount of subcutaneous fat, presence of skin damage and lesions, age, gender, time, and individual differences. In other words, the impedance of the human body varies depending on the area and condition. For example, skin, adipose tissue, and bones have higher impedance than muscles or nerves. While the body's internal resistance is generally very low, around 500Ω, blood vessels, rich in electrolytes, have a resistance of only a few Ω. Skin contains keratin and has a low water content, resulting in a high impedance to current. Skin impedance varies depending on the area, hydration status (e.g., sweat and moisture), and skin temperature. Dry skin has a high impedance of 15KΩ to 1MΩ (500KΩ), while wet skin has a low impedance of 1KΩ. Impedance increases with the amount of subcutaneous fat. Damage to the stratum corneum, such as from abrasions, tears, or shaving, can reduce skin impedance by 50-100%.

[0034] Accordingly, the skin impedance detection module (110) detects skin impedance information that can determine the condition of the skin when the hybrid needle cartridge (130) is driven.

[0035] The processor (120) controls the needle module (131) and the high-frequency module (132) built into one hybrid needle cartridge (130) to apply high-frequency energy to the skin together.

[0036] When a skin-attached electrode plate (not shown) is connected to a designated port, the processor (120) can check whether the skin-attached electrode plate (not shown) is attached to the skin by applying a detection current (a current smaller than the current for generating high-frequency energy) to the surface electrode of the hybrid needle cartridge (130) and the skin-attached electrode plate (not shown).

[0037] The processor (120) can control the port control so that no current is applied even if the skin-attached electrode plate (not shown) is attached to the skin.

[0038] Meanwhile, although not specifically shown in this embodiment, a sensor module (not shown) for detecting skin contact on the surface of the hybrid cartridge (130) may be included.

[0039] The needle module (131) includes a liquid needle for injecting a liquid and an RF needle for applying radiofrequency energy deep into the skin. The liquid needle and the RF needle can be controlled to have different lengths (depth of penetration) and may have different thicknesses. Typically, the liquid needle is controlled to be longer, but the lengths of the liquid needle and the RF needle can also be controlled to be the same.

[0040] The processor (120) can control (sequentially control) the skin invasion timing of the liquid needle and the RF needle and the insertion timing of the liquid needle according to the hybrid needle cartridge control mode.

[0041] Although not specifically illustrated in the drawing, conventional needle cartridges use multiple needles as positive / negative electrodes (+, -), thereby applying high-frequency energy to the deep skin from the tips (non-insulated portions) of the multiple needles. When all needle tips (non-insulated portions) are used as positive / negative electrodes (+, -) to apply high-frequency energy in this way, there is a disadvantage in that the high-frequency energy that can be applied is very limited. That is, there is a problem in that the range of application of high-frequency energy cannot be increased, and the increase in high-frequency energy intensity is limited. In addition, since the needles of conventional needle cartridges have a fixed protrusion length, there is a problem in that the depth of delivery of high-frequency energy cannot be actively controlled.

[0042] To address these issues, referring to FIG. 1, the needle module (131) of the hybrid needle cartridge (130) according to the present embodiment actively controls the protrusion length (skin penetration depth) of the needle in an electric manner using a motor (not shown). Accordingly, the present embodiment can adjust the depth of transmission of high-frequency energy through the needle module (131).

[0043] The processor (120) can be used as an electrode for applying high-frequency energy to the drug needle after injecting all the drug through the drug needle.

[0044] The cartridge vibration module (140) vibrates the hybrid needle cartridge (130) in an electric manner using a motor (not shown) when the hybrid needle cartridge (130) comes into contact with the skin before the needle (i.e., the liquid needle, the RF needle) is invasive into the human body (e.g., the deep skin), thereby causing the skin in contact with the hybrid needle cartridge (130) to vibrate together, and then the needle is invasive into the skin.

[0045] When the skin is vibrated in this way and the needle is inserted, it has the effect of reducing the pain felt by the patient due to the needle insertion.

[0046] The suction module (150) has the effect of preventing the hybrid needle cartridge (130) from slipping during needle penetration and reducing pain felt by the subject due to needle penetration by suctioning and pulling the skin in a negative pressure manner through suction grooves formed at the edge of the skin contact area of ​​the hybrid needle cartridge (130) when the hybrid needle cartridge (130) comes into contact with the skin.

[0047] FIG. 2 is an exemplary drawing illustrating the shape of the surface area of ​​the hybrid needle cartridge in FIG. 1.

[0048] Referring to FIG. 2, the hybrid needle cartridge (130) includes a plurality of needles (liquid needles, RF needles), and the size and shape of the surface area can be changed corresponding to the number of needles included.

[0049] For example, (a) of FIG. 2 is an exemplary view of a side view of a hybrid needle cartridge (130), and (b) of FIG. 2 is an exemplary view showing the shape of the surface area of ​​the hybrid needle cartridge (130) in more detail. As shown in (b) of FIG. 2, depending on the number of needles (liquid needles, RF needles), the needles may be arranged in one row, two rows (2*18), three rows (4*3), or may be arranged in a square shape (5*5, 7*7). The number and arrangement of the liquid needles and RF needles shown in (b) of FIG. 2 are exemplary and are not limiting.

[0050] FIG. 3 is an exemplary diagram for explaining a method of forming an electrode of a hybrid needle cartridge for increasing the application range of high-frequency energy and increasing the intensity of high-frequency energy in FIG. 1, and is an exemplary diagram for explaining that the application range of high-frequency energy is formed widely when a needle (liquid needle, RF needle) protrudes from a hybrid needle cartridge (130) and invades the skin.

[0051] As previously explained, conventional needle cartridges have the problem of making it difficult to increase the range of application of high-frequency energy and limiting the increase in high-frequency energy intensity because they apply high-frequency energy using the needle tip (non-insulating portion).

[0052] To solve this problem, as shown in FIG. 3, the present embodiment forms the entire surface area of ​​the hybrid needle cartridge (130) as an electrode, and forms the needle tip (non-insulating portion) as a counter electrode.

[0053] For example, the entire surface area of ​​the hybrid needle cartridge (130) may be set as a positive electrode (+) and the needle tip (non-insulating portion) may be set as a negative electrode (-), or conversely, the entire surface area of ​​the hybrid needle cartridge (130) may be set as a negative electrode (-) and the needle tip (non-insulating portion) may be set as a positive electrode (+).

[0054] Although not shown in the drawing at this time, the processor (120) may internally include a plurality of switching elements (not shown) for connecting the entire surface area of ​​the hybrid needle cartridge (130) and each needle to a power source (not shown) in order to selectively set (or change the setting) the positive / negative electrodes (+, -) for the entire surface area of ​​the hybrid needle cartridge (130) and the needle tip portion (non-insulating portion). This is because the wider the electrode in contact with the skin, the greater the range and intensity of high-frequency energy.

[0055] Referring to FIG. 3, it can be seen that the range of application of high-frequency energy is widened by generating high-frequency energy through the surface electrode and the needle tip (non-insulating portion) of the hybrid needle cartridge (130) while the needle protrudes from the hybrid needle cartridge (130) and penetrates the skin.

[0056] When the range of application of high-frequency energy is formed wide in this way, the number of treatments and the duration of the treatment can be reduced, which has the effect of reducing the pain of the patient (pain caused by needle invasion).

[0057] At this time, the surface electrode of the hybrid needle cartridge (130) can be formed using an insulating film (e.g., FPCB), and the insulating film (e.g., FPCB) can be formed to have an area designated to have an electrode or circuit printed on it or an electronic component attached to it, and some areas can be formed to be transparent or translucent.

[0058] The hybrid needle cartridge (130) includes a needle module (131) for penetrating deep into the skin and a high-frequency module (132) for generating high-frequency energy.

[0059] The processor (120) can set the needle (liquid needle, RF needle) to one of the positive / negative electrodes (+, -), and can set the surface electrode of the hybrid needle cartridge (130) as one of the negative / positive electrodes (-, +) as the corresponding electrode.

[0060] The high-frequency module (132) can apply high-frequency energy to the human body (i.e., deep skin) through the surface electrode of the hybrid needle cartridge (130) and a needle (liquid needle, RF needle) invasive to the skin, or can apply high-frequency energy to the human body (i.e., deep skin) through the surface electrode of the hybrid needle cartridge (130) and a skin-attached electrode plate (not shown).

[0061] The processor (120) can control the protrusion length (skin penetration depth) of the needle (liquid needle, RF needle) by the needle module (131) and can control the energy intensity of the high-frequency module (132).

[0062] FIG. 4 is a flowchart for explaining a method for a processor to perform an energy intensity control method in FIG. 1.

[0063] Referring to FIG. 4, when the hybrid needle cartridge (130) comes into contact with a human body (e.g., skin), the processor (120) vibrates the hybrid needle cartridge (130) through the cartridge vibration module (140), and intrudes the needle (liquid needle, RF needle) deep into the skin according to a preset protrusion length (S101).

[0064] The processor (120) detects skin impedance in a skin contact state before the needle penetrates the skin, or in a skin contact state after the needle penetrates the skin (S102).

[0065] When skin impedance is detected, the processor (120) calculates a final high-frequency energy setting value by reflecting a high-frequency energy correction value corresponding to the skin impedance value to a preset high-frequency energy setting value (S103). At this time, the high-frequency energy correction value corresponding to the skin impedance value is set to correspond to the skin impedance value within a pre-specified margin range (i.e., the highest high-frequency energy correction value to the lowest high-frequency energy correction value).

[0066] The processor (120) applies high-frequency energy corresponding to a high-frequency energy intensity that reflects the final high-frequency energy setting value calculated by reflecting a high-frequency energy correction value corresponding to a skin impedance value to a preset high-frequency energy setting value to the human body (S104).

[0067] That is, the processor (120) applies high-frequency energy to the human body based on the high-frequency energy intensity set by the user (or administrator), but applies high-frequency energy corrected within a designated margin range in response to the skin impedance according to the skin condition before the needle penetrates the skin or the skin condition after the needle penetrates the skin, thereby enabling the application of high-frequency energy adjusted to suit the skin condition, thereby having the effect of improving energy utilization efficiency.

[0068] FIG. 5 is a flowchart illustrating a method for adjusting the needle protrusion length of a hybrid needle cartridge in FIG. 1.

[0069] Referring to FIG. 5, when the hybrid needle cartridge (130) comes into contact with a human body (e.g., skin), the processor (120) vibrates the hybrid needle cartridge (130) through the cartridge vibration module (140), and intrudes the needle (liquid needle, RF needle) deep into the skin according to a preset protrusion length (S201).

[0070] The processor (120) detects skin impedance in a skin contact state before the needle penetrates the skin, or in a skin contact state after the needle penetrates the skin (S202).

[0071] When skin impedance is detected, the processor (120) corrects the needle protrusion length corresponding to the skin impedance based on a preset lookup table (i.e., a skin thickness lookup table versus skin impedance) (S203).

[0072] The processor (120) automatically adjusts the needle (liquid needle, RF needle) protrusion length in an electric manner according to the corrected value (i.e., the corrected needle protrusion length) (S204).

[0073] In this way, by automatically adjusting the needle protrusion length, for example, when performing a procedure on facial skin, multiple skin, or thigh skin, the needle protrusion length is automatically adjusted to apply high-frequency energy to the human body (i.e., deep skin), that is, by applying high-frequency energy adjusted to suit the skin thickness, there is an effect of improving energy utilization efficiency.

[0074] FIG. 6 is a flowchart for explaining the operation of the first needle cartridge control mode of the needle cartridge type skin care device in FIG. 1.

[0075] Referring to FIG. 6, when the first hybrid needle cartridge control mode is set (S301), the processor (120) vibrates the hybrid needle cartridge (130) through the cartridge vibration module (140) when the hybrid needle cartridge (130) comes into contact with the skin (S302).

[0076] The processor (120) reduces the pain felt by the subject by preventing the hybrid needle cartridge (130) from slipping by sucking and pulling the skin in contact with the hybrid needle cartridge (130) through the suction module (150), and protrudes a needle (medicinal solution needle, RF needle) from the hybrid needle cartridge (130) to inject the medication through the medication needle and then insert only the medication needle back into the hybrid needle cartridge (130) (S303).

[0077] At this time, the protrusion length of the needle can be automatically set according to the skin thickness detected through skin impedance, as described in Fig. 5.

[0078] After the drug needle that has injected the drug in this way is inserted back into the hybrid needle cartridge (130), the processor (120) sets the needle (RF needle) to one of the positive / negative electrodes (+, -), and sets the surface electrode of the hybrid needle cartridge (130) as one of the negative / positive electrodes (-, +) as the corresponding electrode to apply high-frequency energy (S304).

[0079] FIG. 7 is a flowchart for explaining the operation of the second needle cartridge control mode of the hybrid needle cartridge type skin care device in FIG. 1.

[0080] Referring to FIG. 7, when the second hybrid needle cartridge control mode is set (S401), the processor (120) vibrates the hybrid needle cartridge (130) through the cartridge vibration module (140) when the hybrid needle cartridge (130) comes into contact with the skin (S402).

[0081] The processor (120) reduces the pain felt by the subject by suctioning and pulling the skin in contact with the hybrid needle cartridge (130) through the suction module (150) to prevent the hybrid needle cartridge (130) from slipping, and protrudes a needle (medicinal solution needle, RF needle) from the hybrid needle cartridge (130) to penetrate the skin and inject the medicinal solution through the medicinal solution needle (S403).

[0082] When the drug injection is completed, the processor (120) sets both the drug needle and the RF needle to one of the positive / negative electrodes (+, -) without inserting the drug needle, and sets the surface electrode of the hybrid needle cartridge (130) as one of the negative / positive electrodes (-, +) as the corresponding electrode to apply high-frequency energy (S404).

[0083] In this way, by applying high-frequency energy through the surface electrode of the hybrid needle cartridge (130) using both the liquid needle and the RF needle as electrodes without inserting the liquid needle, high-frequency energy can be increased. This has the effect of allowing high-frequency energy to be applied to a wider area than before, and further increasing high-frequency energy than before.

[0084] Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible from the drawings. Accordingly, the technical protection scope of the present invention should be defined by the following claims.
