Description

[Technical Field]

The present invention relates, in General, to skin stimulants, namely, a skin stimulator, made so that many round discs having needles on their peripheral surface, and a holder that allows the placement of round discs at a distance from one another, have corresponding simple designs closely connected to each other and form a drum in which unwanted mutual movement of the discs and holder can be prevented so that dirt from the skin does not get stuck in the drum and when the needles pierce the skin u, they do not cause her severe damage and are protected from breakage and are thus effectively used for a long time.

Further, each of the needles used in the present invention is formed with a polygonal cross section of at least six sides instead of a circular cross section, so that when the skin is pricked with needles, the contact surface of each needle relative to the skin can be reduced, thereby minimizing pain .

[Prior art]

Symptoms of skin aging, i.e. wrinkles formed on the skin mainly relate to collagen in the dermis, which is a layer below the epidermis.

The dermis has a thickness of about 0.7-4 mm and is several times thicker than the epidermis. Skin aging is caused by the fact that the amount of collagen in the dermis is gradually reduced, thus the skin is dried and wrinkles form on it.

To slow down skin aging or remove wrinkles from the skin, it is necessary to constantly replenish the lack of collagen or supply the skin with new collagen. In the state of the art, nutrients such as vitamin C or a peptide necessary for collagen production are applied or sprayed onto the skin to achieve a goal.

However, the above method, in which nutrients such as vitamin C or a peptide necessary for collagen production is applied or sprayed onto the skin, is difficult because 99.7% of the applied or sprayed nutrients cannot pass through the stratum corneum of the epidermis, which is the most the outer layer of the skin, but remain on the skin and finally disappear, and only 0.3% of the applied or sprayed nutrients can penetrate the dermis, so the method is ineffective.

In an attempt to overcome difficulties, a skin stimulator (the so-called microneedle) was proposed and used. The skin stimulator is provided with sharp needles that stimulate the skin and form a microchannel in the skin, thus delivering the nutrients such as vitamin or peptide necessary for collagen production, dermis and making collagen production effective in the dermis.

As an example of skin stimulants, Korean registration of utility model No. 20-395359 (called a microneedle roller) can be mentioned. As disclosed in the official bulletin (publication of the correction), the microneedle roller contains a roller formed by layering at least one round disk and at least one microneedle, which is made in a circular disk or on the surface of a circular disk so that the microneedle can be exposed outside with outer surface of the roller.

The production or delivery of collagen to the dermis by stimulating the skin using microneedles (sharp needles) of the roller can be realized according to the following theory.

It lies in the fact that when the skin is compressed by using sharp needles, a microchannel can form in the skin tissue.

In the above state, when the skin tissue receives a microneedle from microneedles, a new tissue can form in the microneedle due to the natural healing power of the skin, so that the wounded skin tissue can regenerate in the form of elastic new skin.

In addition, the restoration of elastic new skin should be accompanied by the restoration of collagen in the dermis due to the natural healing power that heals the wounded skin, and thus the production and delivery of collagen is carried out.

However, the aforementioned conventional skin stimulant causes difficulties, which follows from its design.

In the skin stimulator, the needles must be firmly inserted into the corresponding holes made in the round disc one by one, so that the productivity of the skin stimulator decreases, thereby increasing the cost of production and reducing the cost-effectiveness of the skin stimulator.

Further, it is almost impossible to reliably or tightly assemble the round discs with one another so that they do not move undesirable, so a normal skin stimulator cannot effectively stimulate the skin, and the needles can break at their ends. Further, the broken ends of the needles can cause severe damage to the skin tissue.

Further, the needles used in a conventional skin stimulator are thin, long needles having a circular cross section, so that when the skin is pricked with needles, the needles pass through pain points on the body, causing the user to feel pain.

[Disclosure]

[Technical Problem]

The present invention was created to solve the above difficulties that exist in the current level of technology.

Accordingly, the present invention is intended to provide a skin stimulant that can be produced using a simple process in which a circular drum disk is formed by combining a metal disk having a plurality of needles on its peripheral surface with a reinforcing polymer material using injection molding with inserts and layering of many metal disks and holders, which increases productivity and economic efficiency, and which is designed so that when alyvanii skin needles needles do not cause severe damage to the skin and can be prevented from breaking, thus the skin stimulator is effectively used for a prolonged period of time.

Further, the present invention serves to provide a skin stimulator in which each of the needles provided on the peripheral surface of the drum is configured to form a polygonal cross section with at least six sides instead of a circular cross section, so that when the skin is pricked with needles, the contact surface of each needles relative to the skin can be reduced, thus minimizing pain.

The present invention also serves to provide a skin stimulator in which the round discs and drum holders have corresponding simple structures and are tightly assembled one with the other, so that the discs and holders can be protected from mutual unwanted movement, due to which the stable operation of the skin stimulator is realized and prevented foreign substances stuck in the drum.

[Technical solution]

In this aspect, the present invention provides a skin stimulant comprising:

a drum comprising a circular disc having a plurality of needles on its peripheral surface, and a holder for arranging the plurality of circular discs at a distance from one another;

and a handle to which the drum shaft is attached so that the drum shaft can rotate, wherein the round disk comprises a metal disk having needles on its peripheral surface and a plurality of locking holes made therein, and is formed by combining the metal disk with a reinforcing polymer material using injection molding with inserts or fusion, in which the surface of the metal disk is coated with a reinforcing polymer material so that the needles protrude outside the reinforcing polymer material The reinforcing polymer material has a hole in the center under the shaft to accommodate the drum shaft, and the holder has a recess made on each of its lateral surfaces and having a depth below the thickness of the reinforcing polymer material covering the surface of the metal disk, and many microprotrusions made on the edge of the recess that the microprotrusions are spaced apart at equal intervals.

In the present invention, each of the needles evenly spaced on the peripheral surface of the circular disk of the drum can be made with inclined surfaces at the corners of its opposite surfaces, so that the inclined surfaces form the tip of each of the needles of a polygonal shape with at least six sides. Therefore, when pricking skin with needles, the contact surface of each needle relative to the skin can be reduced, which minimizes pain.

[Best embodiment of the invention]

Next, a skin stimulator in accordance with a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 5, a skin stimulator 1 according to an embodiment of the present invention stimulates the skin and comprises a drum 3 having a plurality of needles 2 on its outer surface and a handle H rotatably attached to the shaft 4 of the drum 3 so that the drum shaft can rotate. The drum 3 contains many round discs 5, mounted rotatably on the shaft 4 of the drum. Each of the circular disks 5 contains a metal disk 7 having needles 2 on its peripheral surface and a plurality of locking holes 6 made therein, and is formed by combining the metal disk 7 with reinforcing polymer material 8 using injection molding with inserts, in which the surface the metal disk 7 is coated with a reinforcing polymer material 8 so that the needles 2 protrude from the outside of the reinforcing polymer material. Reinforcing polymer material 8 has a hole 9 under the shaft in the center to accommodate the shaft 4 of the drum.

In other words, the metal disk 7 and the reinforcing polymer material 8, made of different materials, are combined with each other using injection molding with liners so that the needles 2 can be stably held in place without removing or separating from the reinforcing polymer material 8 .

In addition, during the molding process, the reinforcing polymer material 8 fills the locking holes 6 made in the metal disk 7, thereby ensuring a strong association of the reinforcing polymer material with the metal disk.

Preferably, the circular discs 5 are tightly assembled with one another by means of physical pressure. However, the circular disks 5 can be combined with each other by welding reinforcing polymer materials 8 of the disks 5 with one another using ultrasonic welding.

In another embodiment, shown in Fig.6 - Fig.9, the present invention provides a skin stimulator, which stimulates the skin and contains a drum 3 having many needles 2 on its outer surface, and a handle H, rotatably attached to the shaft 4 of the drum 3 so that the drum shaft can rotate. The drum 3 contains many round discs 5, mounted rotatably on the shaft 4 of the drum. Each of the circular disks 5 contains a metal disk 7 having needles 2 on its peripheral surface and a plurality of locking holes 6 made therein, and is formed by combining the metal disk 7 with reinforcing polymer material 18 using injection molding with inserts or alloying, wherein the surface of the metal disk 7 is coated with a reinforcing polymer material 18 so that the needles 2 protrude outside the reinforcing polymer material. The reinforcing polymer material 18 has in the center a hole 9 under the shaft to accommodate the shaft 4 of the drum.

In addition, a holder 19 is used for spacing the circular disks between them. The holder 19 has a recess 20, which is made on each side surface of the holder and has a depth under the thickness of the reinforcing polymer material covering the surface of the metal disk, and a plurality of microprotrusions 22 made on the rim 21 of the recess 20, so that the microprotrusions are spaced apart at equal intervals.

Here, the number of microprotrusions 22 is preferably set from 3 to 8. However, the inner surface of the flange can be completely roughened.

Position 13 denotes the end plate.

The operation of the present invention will be described below.

The user grips the handle H in his hand and rolls the drum 3 over the skin, thereby squeezing the skin.

That is, when the drum 3 rolls over the skin, the needles 2 of the drum stimulate the skin.

In the above state, the rotary drum 3 can effectively move over the skin and can effectively stimulate the skin.

In addition, the round discs 5 and the holders 19 in the drum are tightly fixed to each other without mutual movement, so that the needles can effectively stimulate the skin and when pricking the skin with needles the needles do not cause severe damage to the skin and can be protected from breakage, and thus can be used effectively for a long period of time. Also, jamming of dirt falling from the skin in the drum can be prevented, so that the skin stimulant can be used clean.

In the skin stimulated by the skin stimulator 1 in accordance with the present invention, the production and delivery of collagen can be carried out effectively, which contributes to the health of the skin.

Further, the skin stimulator 1 in accordance with the present invention can be changed, as shown in Fig.10 - Fig.12. Here, the skin stimulator comprises a drum 3, comprising a circular disk 5 having a plurality of needles 2 on its peripheral surface, and a holder for arranging the plurality of circular disks at a distance from one another; and a handle H to which the drum shaft 4 is attached so that the drum shaft can rotate, with each of the needles 2 equally spaced on the peripheral surface of the circular disk 5 made with inclined surfaces 100 at the corners of opposite surfaces so that the inclined surfaces 100 form the tip of each of the needles 2 is polygonal in shape from at least six sides.

The skin stimulator according to the second embodiment of the present invention works in the same way as described for the first embodiment, but when the tips of the skin tip off 2, the regenerative power of the skin is affected by the polygonal shape of at least six sides at the tip of each of the needles 2, so that the contact surface of each needle relative to pain points on the skin can be reduced, due to which the pain is minimized.

The skin stimulator 1 in accordance with the present invention can be further modified, as shown in Fig.13 - Fig.15. Here, the skin stimulator comprises a drum 3, comprising a circular disk 5 having a plurality of needles 2 on its peripheral surface, and a holder 119, which allows the plurality of circular disks to be spaced apart from one another; and a handle H to which the drum shaft 4 is attached so that the drum shaft can rotate, wherein the circular disk 5 of the drum 3 has a plurality of locking holes 201 or a plurality of locking grooves 202 made therein, and the holder 119 is provided with a plurality of protrusions 200 formed on each of its side surfaces and inserted into the locking holes or locking grooves.

Here, the protrusion size of the protrusions 200 may be set equal to the depth of the respective locking grooves in the case of locking grooves made in the circular disk, or may be equal to the thickness of the circular disk 5 in the case of locking holes made in the circular disk.

To use the skin stimulator in accordance with the third embodiment, the user grips the handle H in his hand and rolls the drum 3 over the skin, thereby squeezing the skin and stimulating the skin with needles 2.

In the above-described state, the skin stimulator operates in a position in which the protrusions 200 of the holder 119 are fixed in the locking holes 201 or in the locking grooves 202 of the circular disk 5, so that the circular disk and the holder are not spaced from each other. Thus, when the skin is pricked with needles 2, jamming of dirt falling from the skin or other foreign substances between the circular disc 5 and the holder 9 can be prevented, so that, unlike the conventional skin stimulator, the skin stimulator of the present invention can remain clean.

[Industrial Applicability]

The skin stimulator of the present invention can be manufactured by a simple process in which a circular drum disc is formed by combining a metal disc having a plurality of needles on its peripheral surface with a reinforcing polymer material using injection molding with inserts and tightly layering a plurality of metal discs and holders, so that metal discs and holders do not move one another, thereby increasing productivity and economic efficiency. The present invention also provides stable operation of the skin stimulant and prevents foreign substances from getting stuck in the drum, thereby preventing the growth of bacteria in the drum. In addition, when pricking skin with needles, the needles do not cause severe damage to the skin and can be protected from breakage, which ensures effective use for a long period of time.

Further, each of the needles present on the peripheral surface of the drum is made with the formation of a polygonal cross section with at least six sides instead of a circular cross section, so that when pricking skin with needles, the contact surface of each needle relative to the skin is reduced, which minimizes pain.
