Abstract
Description
Micro-needle type skin stimulator
[0001] The present invention relates to a micro-needle type skin stimulator capable of effectively stimulating the skin by adjusting the length of the micro-needle that penetrates the skin of the subject or by adjusting the amount of skin nutrient solution applied to the skin being treated.
[0002] A standard micro-needle skin stimulator is a treatment method utilizing microneedles. The fine needles formed on the device cause physical damage to the skin, stimulating fibroblasts to induce collagen remodeling. It is a therapeutic method that aims to achieve effects such as skin regeneration by creating pathways that allow large molecular weight drugs or drugs that are difficult to polarize to effectively penetrate the skin.
[0003] Generally, the dermis, which forms wrinkles on the skin, constitutes the bottom layer of the epidermis and is composed of a layer that is thicker than the epidermis, with a thickness of about 0.7 mm to 4 mm. In addition, as aging progresses, the amount of collagen in the dermis gradually decreases, and as a result, the skin becomes dry and wrinkles increase.
[0004] Therefore, in order to prevent wrinkles and maintain elastic skin, it is necessary to stimulate the production of collagen or inject new collagen.
[0005] However, when nutrients such as vitamin C or peptides necessary for collagen formation are applied or sprayed on the skin, the amount of the nutrients that pass through the stratum corneum of the skin is only 0.3% of the total content, and the remaining 99.7% cannot pass through the sebum on the outermost layer of the skin and remains on the skin or dries up and disappears.
[0006] Therefore, in order to solve the above-mentioned problems, a microneedle therapy system (MTS) is currently being used.
[0007] At this time, the microneedle therapy system described above is a method of stimulating the skin using a roller with protruding microneedles or creating microchannels in the skin to supply nutrients necessary for collagen formation to the dermis layer.
[0008] The epidermis of the skin is about 0.03 mm to 1 mm thick, and the protruding part of the microneedle penetrates the epidermis and creates a microchannel leading to the dermis beneath the epidermis.
[0009] In other words, nutrients such as ingredients that make the skin elastic or prevent wrinkles can be effectively supplied to the skin through the microchannels formed as described above.
[0010] In addition, by using the aforementioned microneedle roller to create micro-wounds on the skin, collagen is naturally generated through the skin's own natural healing power, thereby achieving a skin regeneration effect.
[0011] In other words, it is possible to restore aged skin by inducing the production of natural healing collagen, such as through laser peeling or chemical peeling procedures, without damaging the epidermal layer.
[0012] Microneedle rollers are currently being used as one of the microneedle-type skin stimulators that form microchannels in the skin to improve stretch marks and wrinkles, as well as to restore acne scars and burn scars, by stimulating the skin through microchannels as described above or effectively supplying nutrients such as vitamin C and peptides to the dermis layer containing collagen to the skin tissue.
[0013] Meanwhile, conventional micro-needle type skin stimulators had the disadvantage that the process of stimulating the skin with a needle and the process of applying an ampoule to the stimulated skin could not occur simultaneously, and the user could not actively control the depth of needle penetration, the amount of ampoule applied, and the timing of application during the procedure.
[0014] The present invention was devised to solve the aforementioned problems, and aims to provide a micro-needle type skin stimulator capable of effectively stimulating the skin by allowing the operator to adjust the length of the needle penetrating the patient's skin or the amount of skin nutrient solution applied to the skin during the procedure.
[0015] A micro-needle type skin stimulator according to one embodiment of the present invention may include a main body containing a skin nutrient solution containing nutrients necessary for collagen formation applied to the skin, a discharge volume control unit provided at the top of the main body and having one or more holes formed therein and capable of rotation, a needle length control unit coupled to the top of the main body and in contact with the discharge volume control unit, capable of adjusting the position of the needles by rotating an outer tube to move a plurality of needles contained therein in the longitudinal direction of the main body, and an upper case that protrudes through the upper hole of the needle length control unit, has one end surface in contact with the skin of a patient, and has a plurality of holes formed on the one end surface through which the needles can pass at a position corresponding to the position of the needles.
[0016] According to one embodiment, the discharge volume control unit is rotated by the operator to control the amount of skin nutrient solution discharged from the main body, and the solution can be discharged through capillary action from the gap at the bottom of the needles, and when pressure is applied to the skin of the patient when the upper case's end surface is in close contact with the patient's skin, the upper case retracts, and the length of the needles protruding through the plurality of holes formed on the upper case's end surface varies according to the position of the needles, thereby allowing the depth of penetration of the needles into the patient's skin (S) to be controlled.
[0017] According to one embodiment, the needle length adjustment part may include a needle plate having guide pins formed symmetrically on the lower left and right sides, and having a gap formed in the portion where the needle ends are connected so that the skin nutrient solution can pass through, a bottom part having one or more holes that correspond to all positions of holes formed in the discharge amount adjustment part at a specific position, an inner tube that accommodates the needle plate inside and has a guide slit into which the guide pin of the needle plate is inserted to guide the needle plate when it moves up and down, and an outer tube that accommodates the inner tube inside and has a spiral groove formed on its inner surface into which the guide pin of the needle plate, which protrudes through the guide slit of the inner tube, is inserted.
[0018] According to one embodiment, when the outer tube is rotated, the needle plate can move up and down along the guide slit of the inner tube and the spiral groove of the outer tube by the guide pin.
[0019] The upper case may include a front cover having holes formed that correspond to the positions of the needles formed on the needle plate, and a catch portion protruding from the end extending downward from the edge of the front cover to catch on the edge of the upper hole of the outer tube.
[0020] Additionally, the device further includes a spring in which the needles penetrate the inner diameter, one end contacts the inner surface of the front cover, and the other end contacts the upper surface of the needle plate. When the front cover is pressed against the skin of the patient and pressure is applied, the upper case retracts and the spring is compressed, causing the needles formed on the needle plate to penetrate the holes formed in the front cover and penetrate the skin of the patient, and the skin nutrient solution supplied by capillary action can be discharged from the gaps below the needles formed on the needle plate.
[0021] According to one embodiment, the upper case is made of a transparent plastic material so that the operator can visually check the length of the needle protruding from the front cover.
[0022] According to one embodiment, the upper case is made of copper material, and the rim of the upper hole of the outer tube is made of a neodymium magnet, so that when the upper case moves forward or backward, an eddy current may flow in the upper case in a direction that hinders the movement of the upper case.
[0023] According to the present invention, micro-needles stimulate the skin to induce a stimulating response, thereby promoting skin regeneration and stimulating the production of collagen and elastin to improve skin elasticity.
[0024] In addition, according to the present invention, an immune response is promoted by skin stimulation with micro-needles, thereby activating the skin's defense function and causing the skin to secrete various growth factors, which can heal damaged tissue and promote regeneration.

[0033] Hereinafter, various embodiments of the present invention are described with reference to the accompanying drawings. However, this is not intended to limit the present invention to specific embodiments and should be understood to include various modifications, equivalents, and / or alternatives of the embodiments of the present invention.
[0034] Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification are denoted by similar reference numerals.
[0035] Additionally, terms such as “…part,” “…unit,” and “module” described in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware, software, or a combination of hardware and software.
[0036] Furthermore, throughout the specification, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "electrically connected" with other components in between.
[0037] Furthermore, when a part is said to "include" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but rather may include additional components, and it should be understood as not excluding in advance the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
[0038] FIG. 1 is a drawing illustrating a micro-needle type skin stimulator (1) according to one embodiment of the present invention. FIG. 2 and FIG. 3 are drawings illustrating micro-needle skin stimulation being performed on the skin (S) of a patient using a micro-needle type skin stimulator (1) according to one embodiment of the present invention.
[0039] The micro needle skin stimulator (1) can be used to keep the skin healthy and enhance its beauty by stimulating the dermis layer, which is the deep part of the skin, with micro needles. This stimulation can promote blood circulation in the skin and increase water secretion, thereby making the skin moist.
[0040] In addition, it plays a role in reducing irritation through the skin's irritation response and strengthening the skin, and can help improve skin condition by activating skin metabolism.
[0041] Specifically, microneedles can create tiny holes in the patient's skin to promote skin regeneration and stimulate collagen production. This is called microneedling.
[0042] At this time, the depth and density of the needles can be adjusted according to the intensity and purpose of the skin care.
[0043] For skin regeneration and collagen production, needles with a depth between 1.5mm and 2.5mm can generally be used. Deeper needles can reach the dermis layer to stimulate the production of collagen and elastin. In this case, a high-density needle array can create more micro-wounds to promote skin regeneration.
[0044] For skin surface improvement (e.g., acne scars, skin texture improvement), needles with a depth between 0.5mm and 1.5mm may be used. This can improve the texture of the skin surface by stimulating the upper layers of the epidermis and dermis.
[0045] For skin whitening and improvement of pigmentation, shallow needles with a depth between 0.25 mm and 0.5 mm may be used. This allows for the alleviation of pigmentation by focusing on the epidermal layer. In this case, excessive stimulation can be avoided by primarily using a low-density needle array.
[0046] To promote hair growth, needles with a depth of 0.5 mm to 1.0 mm can be used to stimulate the scalp. In this case, needles placed at an appropriate density can increase blood flow to the scalp and promote hair growth.
[0047] Referring to FIGS. 1 to 3, a micro-needle type skin stimulator (1) according to one embodiment of the present invention may include a main body (100), an discharge control unit (200), a needle length control unit (300), and an upper case (400).
[0048] The main body (100) contains a skin nutrient solution containing nutrients necessary for collagen formation applied to the skin. Examples of skin nutrient solutions include hydrocoarbonoxin (Hyaluronic Acid), fertiide (Ferulic Acid), and vincamole (Vitamin C). These ingredients can maintain the moisture content of the skin, reduce inflammation, and promote skin regeneration to make the skin younger and firmer.
[0049] The discharge control unit (200) is provided at the top of the main body (100), has one or more holes formed therein, and is rotatable. As described below, the position of one or more holes formed in the bottom portion (323) of the inner tube (320) that contacts the discharge control unit (200) in the needle length control unit (300) and the position of one or more holes formed in the discharge control unit (200) coincide at a specific position, so that the skin nutrient solution can be supplied to the maximum at that specific position. However, the amount of skin nutrient solution discharged can be controlled by rotating the discharge control unit (200) so that the holes are offset from each other.
[0050] The needle length adjustment unit (300) is coupled to the upper part of the main body (100), and the inner tube (320) of the needle length adjustment unit (300) is in contact with the discharge adjustment unit (200), and by rotating the outer tube (310), the multiple needles (332) contained therein are moved in the longitudinal direction of the main body, thereby allowing the position of the needles (332) to be adjusted.
[0051] The upper case (400) protrudes through the upper hole of the needle length adjustment part (300), and one end surface comes into contact with the skin of the patient, and a plurality of holes are formed on the one end surface so that the needles (332) can pass through at positions corresponding to the positions of the needles (332).
[0052] The operator can rotate the discharge control unit (200) to control the amount of skin nutrient solution discharged from the main body (100), thereby allowing it to be discharged through capillary action from the gap at the bottom of the needles (332).
[0053] Additionally, when the operator applies pressure by pressing the upper case (400) against the skin of the patient, the upper case (400) retracts, and depending on the position of the needle (332), the length of the needle (332) penetrating and protruding from the plurality of holes formed on the upper case (400) can be varied. By doing so, the depth to which the needle (332) penetrates the skin (S) of the patient can be controlled.
[0054] FIG. 4 is an exploded perspective view of the main body (100), the needle length adjustment unit (300), and the upper case (400). FIG. 5 is an exploded perspective view of the needle length adjustment unit (300) and the upper case (400). FIG. 6 is an overall exploded perspective view of the micro-needle type skin stimulator (1) according to the present invention.
[0055] Referring to FIGS. 4 to 6, the needle length adjustment unit (300) includes a needle plate (330), an inner tube (320), and an outer tube (310).
[0056] The needle plate (330) is coupled to one end of a plurality of the needles (332), and a gap is formed in the part where the one end of the needle (332) is coupled so that the skin nutrient solution can pass through, and guide pins (335) are formed symmetrically protruding on the lower left and right sides.
[0057] The inner tube (320) has a bottom portion (323) having one or more holes that correspond to all positions of the holes formed in the discharge control portion (200) at specific positions, accommodates the needle plate (330) inside, and has a guide slit (325) into which the guide pin (335) of the needle plate (330) is inserted to guide the needle plate (330) when it moves up and down.
[0058] As described above, the inner tube (320) has a bottom portion (323) having one or more holes that correspond to all positions of the holes formed in the discharge control portion (200) at a specific location, and the bottom portion (323) contacts the discharge control portion (200). At this time, the amount of skin nutrient solution discharged from the main body (100) can be controlled by rotating the discharge control portion (200) so that it is offset from the positions of the holes in the bottom portion (323).
[0059] The outer tube (310) accommodates the inner tube (320) inside, and a spiral groove (315) is formed on the inner surface into which the guide pin (335) of the needle plate (330), which protrudes through the guide slit (325) of the inner tube (320), is inserted.
[0060] When the outer tube (310) is rotated, the needle plate (330) can move up and down along the guide slit (325) of the inner tube (320) and the spiral groove (315) of the outer tube (310) by the guide pin (335).
[0061] The upper case (400) includes a front cover (405) and a locking part (407).
[0062] The front cover (405) has holes formed that correspond to the positions of the needles (332) formed on the needle plate (330).
[0063] The catch portion (407) protrudes so as to catch on the edge (318) of the upper hole of the outer tube (310) at the end extending downward from the edge of the front cover (405).
[0064] Meanwhile, a spring (500) may be further provided, in which the needles (332) penetrate the inner diameter, one end contacting the inner surface of the front cover (405), and the other end contacting the upper surface of the needle plate (330). The upper case (400) and the needle plate (330) are separated from each other by this spring (500), but when the practitioner presses the upper case (400) against the patient's skin and applies force, the spring (500) is compressed and the needles (332) can protrude through the hole in the front cover (405) of the upper case (400).
[0065] That is, when the front cover (405) is pressed against the skin of the patient and pressure is applied, the upper case (400) retracts and the spring (500) is compressed, and the needles formed on the needle plate (330) penetrate the holes formed on the front cover (405) and penetrate the skin of the patient, and the skin nutrient solution supplied by capillary action can be discharged from the gaps below the needles formed on the needle plate (330).
[0066] FIG. 7 is a drawing showing the case where the upper case (400) is made of a transparent plastic material. Referring to FIG. 7, the upper case (400) is made of a transparent plastic material so that the operator can visually check the length of the needle (332) protruding from the front cover (405). Specifically, acrylic ion or polycarbonate may be used as the transparent plastic material.
[0067] Meanwhile, when the practitioner presses the upper case (400) against the skin of the subject, the needle (332) needs to be gently penetrated into the skin.
[0068] FIG. 8 is a drawing showing the case where the upper case (400) is made of a conductive metal made of copper.
[0069] Referring to FIG. 8, the upper case (400) is made of copper material, and the rim (318) of the upper hole of the outer tube (310) is made of a neodymium magnet, so that when the upper case (400) moves forward or backward, an eddy current may flow in the upper case (400) in a direction that hinders the movement of the upper case (400).
[0070] Eddy current is a current generated through the phenomenon of electromagnetic induction. When the upper case (400) made of copper material moves forward or backward in the longitudinal direction of the main body (100) inside the rim (318) of the upper hole of the outer tube (310) made of a neodymium magnet, the electromagnetic field changes, and electromagnetic induction occurs, thereby generating an eddy current.
[0071] At this time, the eddy current is generated in a direction that hinders the movement of the upper case (400) made of copper material. Therefore, when the practitioner presses the upper case (400) against the skin of the patient, the needle (332) can be gently penetrated into the skin, allowing the patient to receive treatment comfortably.
[0072] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art can make various modifications and variations from this description.
[0073] Accordingly, the scope of the present invention should not be limited to the described embodiments, and all things equivalent to or having equivalent variations to the claims set forth below, as well as the claims set forth below, shall be considered to fall within the scope of the concept of the present invention.
