Description

The present invention relates to a skin stimulation device and a skin stimulation method, and in particular to a skin stimulation device and a skin stimulation method that stimulate the skin by pressing it with a cone-shaped stimulation protrusion.

Acupuncture has long been known as a form of traditional Chinese medicine that uses needles to stimulate acupuncture points, known as pressure points, scattered throughout the body to improve physical ailments, and has been attracting attention from various research institutes and health organizations for its promising effectiveness.

One type of acupuncture treatment that has beauty aims is cosmetic acupuncture, which directly stimulates the skin and muscles to improve physical conditions such as skin quality that cause acne, nasolabial folds, wrinkles, sagging skin, and blemishes, thereby achieving healthy beauty (see, for example, Patent Documents 1 and 2).

For example, Patent Document 1 discloses a needle for acupuncture treatment that allows stimulation of the body for a long period of time.
Specifically, as a cosmetic surgery/cosmetic treatment with few side effects on the body, threads are implanted into the body to activate skin cells, and the threads are impregnated with a solution such as a collagen solution to improve the stimulating effect.Furthermore, by simply adjusting the length of the folded thread, the threads implanted in the body can be easily removed from the injection needle.

As another method of stimulating acupressure points, Patent Document 2 discloses a beauty and health device that provides a greater synergistic effect between the massage effect of the rolling rollers, the effect of other energy being released through the rollers, and the metabolic activation effect of stimulating acupressure points at the same time.

Specifically, a roller having a protrusion on its cylindrical outer peripheral surface, or a roller having a non-cylindrical outer peripheral surface, is rotatably supported at one end of a main body having a gripping portion, and energy is transmitted from an energy generating unit provided inside the roller to the roller.
In this way, stimulating acupressure points with acupuncture or beauty and health devices can activate the body's metabolism and improve physical conditions such as skin quality that cause acne, nasolabial folds, wrinkles, sagging skin, and blemishes, resulting in healthy beauty.

Patent No. 5128715 Japanese Patent Application Laid-Open No. 11-192275

However, since acupuncture treatment can only be performed by qualified people such as doctors or acupuncturists, there was a problem that general users could not easily perform the treatment. Currently, in Japan, only doctors and people with a license as a nationally qualified acupuncturist can perform acupuncture professionally, and needle insertion as described in the above-mentioned Patent Document 1 can only be performed by doctors and acupuncturists. In other words, general users could not easily perform the treatment for beauty purposes on their own.
Additionally, because cosmetic acupuncture involves inserting needles directly into the skin, there is a perception that it is painful, which can leave patients feeling uneasy, making cosmetic acupuncture less likely to become widespread.

On the other hand, in beauty and health devices such as those described in Patent Document 2, rollers with protrusions on their cylindrical outer surface or rollers with non-cylindrical outer surface stimulate the skin and acupressure points, so treatment can be easily performed by anyone, even if they are not qualified, as is the case with magical acupuncture treatments.

However, when stimulating with protrusions on the outer peripheral surface of a cylindrical shape or with a non-cylindrical outer peripheral surface, the stimulation is weak because it can only reach the surface of the skin, and it is not possible to stimulate acupressure points efficiently.

In addition, to supplement the weak stimulation, an energy generating unit is installed inside the roller, and examples of the energy generating unit include ultrasonic, low frequency, and high frequency generators, but since generating ultrasonic, low frequency, and high frequency requires electricity, it is not economical. Also, in order to secure a power source, it is not possible to easily perform stimulation anytime, anywhere.
Furthermore, in the case of a portable beauty and health device, the necessary power supply must be built in, which increases the weight of the entire device, and causes fatigue every time the device is used.

The present invention was made in consideration of these points, and aims to provide a stimulation device that can easily provide appropriate stimulation to appropriate locations without using electricity.

In order to solve the above problem, the present invention provides a skin stimulation device that stimulates the skin by pressing it with a cone-shaped stimulation protrusion, characterized in that the stimulation protrusion has a tip stimulation section at the tip of the stimulation protrusion that is formed to a degree that it does not pierce the skin when pressed, and a height at which the tip stimulation section remains within the subcutaneous tissue when pressed. This allows the tip of the stimulation protrusion to remain in the subcutaneous tissue without piercing the skin.

The present invention also provides a skin stimulation method for stimulating the skin by pressing the skin with a cone-shaped stimulation protrusion, the method comprising the steps of pressing a tip stimulation section formed at the tip of the stimulation protrusion so as not to pierce the skin against the skin, and the step of the tip of the stimulation protrusion reaching and remaining in the subcutaneous tissue. As a result, the tip of the stimulation protrusion remains in the subcutaneous tissue without piercing the skin.

According to the skin stimulation device and skin stimulation method of the present invention, the tip of the stimulation protrusion does not pierce the skin but remains in the subcutaneous tissue, so it is possible to easily stimulate the appropriate subcutaneous tissue without using electricity.

First Embodiment
FIG. 1 is a front view, a top view, and a side view of cosmetic acupuncture according to a first embodiment.
As shown in Figure 1, cosmetic acupuncture 100 comprises a cylindrical roller unit 110, a roller holding frame 120 that holds roller unit 110 so that it can rotate freely, and a handle 130 fixed to one side of roller holding frame 120. While holding handle 130, the user places roller unit 110 on the skin at the desired location to be stimulated, and rotates roller unit 110 in accordance with the rotational direction of roller unit 110 to stimulate the user's skin and acupoints and enhance the cosmetic effect.

The roller part 110 is a cylindrical roller made of a metal such as a titanium alloy. On the peripheral side of the roller part 110, cone-shaped stimulation protrusions 111 are continuously arranged along the direction of rotation of the roller part 110.

At the tip of the stimulation protrusion 111, a tip stimulation section 112 is formed with a flat surface with a cross-sectional width of about one hair. This prevents the tip of the stimulation protrusion 111 from piercing the skin when the stimulation protrusion 111 comes into contact with the user's skin. Furthermore, by forming the tip of the stimulation protrusion 111 with a flat surface with a cross-sectional width of about one hair, it is possible to approximate the stimulation of a needle used in acupuncture treatment.

The stimulation protrusions 111 and tip stimulation portion 112 that make up the roller portion 110 are made of a titanium alloy with high hardness, so even if the tip is made thin like the tip stimulation portion 112, it is possible to reduce wear of the stimulation protrusions 111 due to friction with the skin.

Furthermore, titanium alloys are known to oxidize immediately when exposed to air, forming a strong oxide film on the surface. By forming this oxide film on the surface, even if the stimulation protrusions 111 and tip stimulation parts 112 come into contact with the user's sweat or lymphatic fluid, the metal components will not dissolve, making it less likely to cause metal allergies.

The roller holding frame 120 is a U-shaped frame that holds the roller unit 110 by clamping it from both sides. The roller holding frame 120 holds the roller unit 110 rotatably using bolts 121.

The handle 130 is a rod that is fixed vertically to the bottom side of the roller holding frame 120 in the opposite direction to the holding side of the roller unit 110. While holding the handle 130, the user rotates the roller unit 110 while placing the roller unit 110 against the user's skin.

The roller holding frame 120 and handle 130 rarely come into direct contact with the user's skin, so by making them from stainless steel, the manufacturing cost can be reduced. Stainless steel is also a metal that does not oxidize easily, so like titanium, the metal components do not dissolve, making it less likely to cause metal allergies.

Although the handle 130 is shown in FIG. 1 as having a rod-like shape, it may be configured in other shapes as long as the shape is easy for the user to grip.
Although the roller holding frame 120 and the handle 130 are fixed vertically in the example shown, they may be fixed at a predetermined angle. Furthermore, the angle may be freely adjustable.

FIG. 2 shows front, top and side views showing details of the stimulation protrusions.
As shown in FIG. 2, the stimulation protrusion 111 has, for example, a quadrangular pyramid shape, and at the tip of the stimulation protrusion 111 is formed a planar tip stimulation portion 112 having a cross-sectional width of about one hair.

Specifically, the bottom surface of the stimulation protrusion 111 is formed in the shape of a parallelogram measuring 2.6 mm x 3.0 mm, and the height from the bottom surface to the plane of the tip stimulation portion 112 is 2.07 mm, forming a square pyramid.

In addition, a 0.15 mm x 0.12 mm planar tip stimulation section 112 is formed at the tip of the stimulation protrusion 111 parallel to the user's skin with which it comes into contact. Generally, the cross-sectional width of Japanese hair is about 0.05 mm to 0.15 mm, and a flat surface with a cross-sectional width of about the width of a hair will not pierce the skin. By forming the tip stimulation section 112 at the tip of the stimulation protrusion 111 that comes into contact with the user's skin in this way, the stimulation protrusion 111 can provide an appropriate stimulation without piercing the skin.

In addition, a common needle treatment for cosmetic acupuncture involves a shallow needle insertion technique called oblique insertion, in order to stimulate areas close to the skin surface. Oblique insertion is when the needle is inserted at an angle of approximately 30 to 60 degrees, preferably 45 degrees, to the skin surface.

In the cosmetic acupuncture 100 of this embodiment, the shape of the stimulation protrusion 111 is made into the above-mentioned quadrangular pyramid shape, so that it can stimulate the skin at an angle of approximately 30 degrees to 60 degrees, preferably 45 degrees.

FIG. 3 is a diagram showing the moving direction of the roller unit and the points stimulated by the stimulating protrusions.
FIG. 3A shows stimulation points 122A when stimulation protrusions 111 having a parallelogram-shaped bottom surface are arranged on the peripheral side surface of roller unit 110. FIG.

As shown in FIG. 3(A), the bottom surface of the stimulation protrusions 111 is formed into a parallelogram, and the stimulation protrusions 111 are arranged continuously on the peripheral side surface of the roller part 110, so that the stimulation protrusions 111 are arranged continuously in the direction of an inclined straight line L-A that forms a predetermined angle with the rotation direction M of the roller part 110.

Similarly, the tip stimulation portion 112 formed at the tip of the stimulation protrusion 111 is arranged continuously in the direction of an inclined straight line L-A that forms a predetermined angle with respect to the rotation direction M of the roller portion 110.

As a result, the stimulation points 122A are stimulated at an angle that forms a predetermined angle with respect to the rotation direction M of the roller unit 110, so that the stimulation points 122A can be stimulated in a dispersed manner.

In addition, the stimulation point 122A is stimulated at an angle to the rotation direction M of the roller unit 110, so that the skin is stimulated and moves in a direction that is inclined from the direction of movement of the roller unit 110, thereby enhancing the skin tightening effect.

In FIG. 3(A), the stimulating protrusions 111 whose bottom surfaces are formed in a parallelogram are arranged on the peripheral side surface of the roller part 110, but as shown in FIG. 3(B), the stimulating protrusions 111 whose bottom surfaces are formed in a rectangular shape may also be arranged on the peripheral side surface of the roller part 110.

FIG. 3B shows stimulation points 122B when stimulation protrusions 111 having rectangular bottom surfaces are arranged on the peripheral side surface of roller portion 110.

As shown in FIG. 3B, the bottom surface of the stimulation protrusions 111 is formed into a rectangle, and the stimulation protrusions 111 are arranged continuously on the peripheral side surface of the roller part 110, so that the stimulation protrusions 111 are arranged continuously in the direction of a straight line L-B parallel to the rotation direction M of the roller part 110.

Similarly, tip stimulation portions 112 formed at the tips of stimulation protrusions 111 are also arranged continuously along a straight line LB direction parallel to the rotation direction M of roller portion 110 .
As a result, stimulation point 122B is stimulated parallel to the rotation direction of roller unit 110, allowing the user to move roller unit 110 smoothly.

FIG. 4 is a cross-sectional view showing the structure of the skin and cosmetic acupuncture before, during and after use.
As shown in FIG. 4, the skin is composed of three layers: the epidermis, the dermis, and the subcutaneous tissue.
The epidermis is composed of the dermal membrane, stratum corneum, granular layer, spinous layer, and basal layer from the surface side, and has a thickness of about 0.2 mm. The dermis is composed of collagen, elastin, fibroblasts, and matrix, and has a thickness of about 2 mm.

Subcutaneous tissue is mainly made up of subcutaneous fat, and contains capillaries and lymphatic vessels that deliver nutrients and excrete waste products. Muscles are also structured beneath the skin, via the fascia.

The causes of "wrinkles" and "sagging," which are generally considered to be the enemies of beauty, are believed to lie in the epidermis or dermis. For example, collagen and elastin, which form the structure of the dermis, are fibrous components that keep the dermis in shape, and the loosening of these components is believed to be the main cause of "sagging."

In other words, when the purpose is cosmetic acupuncture treatment, there is no need to insert the needles deeply; improvements are often achieved by stimulating the epidermis and areas near the dermis.
For this reason, in the cosmetic acupuncture 100 of this embodiment, the height of the stimulation protrusion 111 is formed at 2 mm to 2.2 mm, which is the height at which the tip stimulation portion 112 remains within the subcutaneous tissue when pressed, and preferably at a height of 2.07 mm to the plane of the tip stimulation portion 112. Therefore, combined with the distance the user presses the roller portion 110 toward the skin, it is possible to sufficiently stimulate the 2.2 mm up to the epidermis and dermis that require stimulation.

In addition, because the tip of the stimulation protrusion 111 is formed with a tip stimulation section 112, it does not pierce the skin. It also allows stimulation to be applied to the appropriate area without damaging tissues such as subcutaneous tissue, fascia, and muscle.

The cosmetic acupuncture 100 of this embodiment can stimulate not only human skin, but also the scalp where hair grows, or the skin of an animal where the surface is covered with body hair. For example, when stimulating the human scalp, if the height of the stimulation protrusion 111 is 2 mm to 2.2 mm, the volume of the hair may prevent the tip stimulation part 112 from reaching the subcutaneous tissue.

In this case, by forming the stimulation protrusion 111 to a height of 2 mm to 3.5 mm, preferably 2.58 mm or 3.45 mm, the tip stimulation section 112 can reach the subcutaneous tissue and sufficiently stimulate the epidermis and 2.2 mm up to the dermis, which require stimulation, even if the epidermis is covered with hair.

The height of the stimulation protrusions 111 of the cosmetic acupuncture 100 of this embodiment is formed on the premise that it will stimulate human skin, but when used on the skin of animals other than humans, the height of the stimulation protrusions 111 can be formed appropriately to match the structure of the skin of the animals other than humans, so that the tip stimulation portion 112 remains within the subcutaneous tissue.

In addition, the height of the stimulation protrusions 111 may be changed as desired when used in areas where the stimulation is insufficient due to the height of the stimulation protrusions 111 being between 2 mm and 2.2 mm, as well as when the surface of the skin is covered with hair.

FIG. 5 is a cross-sectional view showing an example of the formation of a heat source.
As shown in FIG. 5 , cosmetic acupuncture 100 can be equipped with a heat source 140 .
The roller part 110 of the cosmetic acupuncture 100 is made of a titanium alloy, so when the temperature is low, such as in winter, if the roller part 110 is placed directly against the user's skin, the user may feel cold and uncomfortable.

In this case, because the cosmetic acupuncture 100 is equipped with a heat source 140, the roller unit 110 heats up to an appropriate temperature, and the user does not feel cold or uncomfortable even when the roller unit 110 is placed directly against the skin.

As a specific example, as shown in FIG. 5(A), the heat source 140 provides a space inside the roller unit 110, and hot water is poured inside through a water inlet 141 provided on the side of the roller unit 110. As a result, the roller unit 110 is heated by the hot water poured into the heat source 140, allowing the user to use the cosmetic acupuncture 100 comfortably.

As another example, as shown in FIG. 5(B), the heat source 140 provides a space inside the handle 130, and hot water is poured inside through a water inlet 141 provided at the end of the handle 130. As a result, the stainless steel handle 130 is heated by the heat source 140, and the heat of the heat source 140 is conducted to the stainless steel roller holding frame 120 and the titanium alloy roller part 110, allowing the user to use the cosmetic acupuncture 100 comfortably.

Second Embodiment
Next, the second embodiment of the present invention will be described. The cosmetic acupuncture of this embodiment is almost the same as the configuration shown in the first embodiment, except for the shape of the roller part. Therefore, the components almost the same as those of the first embodiment are given the same reference numerals and the description thereof will be omitted as appropriate.

FIG. 6 is a front view of cosmetic acupuncture according to the second embodiment.
As shown in Figure 6, cosmetic acupuncture 100 comprises two cylindrical roller units 110A and 110B, a roller holding frame 120 that holds roller units 110A and 110B in a rotatable manner, and a handle 130 fixed to one side of roller holding frame 120.

Roller unit 110A and roller unit 110B are held by roller holding frame 120 so as to rotate independently of each other.
Because roller unit 110A and roller unit 110B rotate independently, for example, by rotating only roller unit 110B without rotating roller unit 110A, a circle centered on roller unit 110A can be drawn on the user's skin.

As described above, by rotating roller unit 110A and roller unit 110B independently, the mobility of cosmetic acupuncture 100 is improved, and the user can smoothly stimulate the skin even in areas with complex shapes such as the chin and cheeks.

In addition, roller unit 110A and roller unit 110B each independently grasp and stimulate the fine muscles near the user's skin, allowing stimulation to be tailored to each area. It is also possible to provide a comfortable stimulation to the user.

Although the cosmetic acupuncture 100 of this embodiment is configured with two roller units 110A and 110B, it can also be configured using three or more roller units 110.
In addition, the cosmetic acupuncture 100 of this embodiment is configured with two roller units 110A and roller unit 110B arranged in the direction of the rotation axis, but it is also possible to configure multiple roller units 110 arranged in the rotation direction, or in the rotation direction and the rotation axis direction.

In addition, the example in Figure 6 shows an example in which stimulation protrusions 111 with a parallelogram-shaped bottom surface are arranged on the peripheral side surface of roller unit 110, and the arrangement direction of stimulation protrusions 111 on roller unit 110A and roller unit 110B is the same, but they may also be arranged facing inward or outward relative to each other.

FIG. 7 is a front view showing the details of the handle which is configured to be extendable and retractable.
As shown in FIG. 7, the handle 130 includes handles 130A and 130B configured to be adjustable in length.

The cosmetic acupuncture needle 100 is made small and portable, but there may be times when you need to stimulate areas that are difficult to reach. In this case, by extending the handle 130 as shown in Figure 7, you can stimulate areas that are difficult to reach.

Specifically, the roller holding frame 120 is fixed to one end of the handle 130A, and a male screw 131A is formed at the other end. A female screw 131B is formed at one end of the handle 130B, and by connecting and fastening the male screw 131A and the female screw 131B, the length of the handle 130B is extended to the length of the handle 130A.

In the present embodiment of the cosmetic acupuncture 100, the male screw 131A and the female screw 131B are used to connect the handle 130A and the handle 130B, but it is also possible to insert the handle 130B, which has a smaller diameter than the handle 130A, into the inside of the cylindrical handle 130A and slide it to extend it.

Third embodiment
Next, the third embodiment of the present invention will be described. The cosmetic acupuncture of this embodiment is almost the same as the configuration shown in the first embodiment, except that the arrangement shape of the stimulation protrusion is different. Therefore, the components that are almost the same as those of the first embodiment are given the same symbols, and the description thereof is omitted as appropriate.

FIG. 8 is a front view of cosmetic acupuncture according to the third embodiment.
As shown in FIG. 8, the cosmetic acupuncture 100 has stimulation protrusions 111 arranged in a plane.
When the stimulation protrusions 111 are arranged in a plane, the bottom surfaces of the stimulation protrusions 111 may be connected to each other, or the stimulation protrusions 111 may be attached to a plate material or the like.

The cosmetic acupuncture 100 of the third embodiment has stimulating protrusions 111 arranged in a flat plane, so that the user can, for example, place it on top of the bed on which the user sleeps, or the user can sleep on the floor on which the cosmetic acupuncture 100 of the third embodiment is placed, or lean against the cosmetic acupuncture 100 placed on a wall, thereby stimulating the user's skin.
Even in this case, a tip stimulation portion 112 is formed at the tip of the stimulation protrusion 111 in a planar shape, so that the stimulation protrusion 111 does not pierce the skin to be stimulated by the cosmetic acupuncture needle 100.

Fourth embodiment
Next, the fourth embodiment of the present invention will be described. The cosmetic acupuncture of this embodiment is almost the same as the configuration shown in the first embodiment, except that the arrangement shape of the stimulation protrusion is different. Therefore, the components almost the same as those of the first embodiment are given the same symbols and the description thereof is omitted as appropriate.

FIG. 9 is a perspective view of a cosmetic acupuncture according to the fourth embodiment.
As shown in FIG. 9 , the cosmetic acupuncture 100 includes stimulation protrusions 111 arranged in a plane and a bandage 150 .

The cosmetic acupuncture 100 according to the fourth embodiment differs from the cosmetic acupuncture 100 according to the first to third embodiments in that the stimulation is given temporarily by the user's stimulating action, in that the stimulation protrusions 111 are attached to the desired position of the user's skin using a bandage 150, allowing the stimulation to be given continuously.

Specifically, an adhesive surface 151 is laminated on one side of the adhesive bandage 150, and the bottom surfaces of the stimulation projections 111 are adhered to the adhesive surface 151.
The user places the tip stimulation portion 112 formed at the tip of the stimulation protrusion 111 at a desired position facing the skin, and adheres the stimulation protrusion 111 to the user's skin with a bandage 150 so as to cover the bottom surface of the stimulation protrusion 111.

This allows the stimulation protrusions 111 to be fixed at the desired positions on the user's skin, so that stimulation can continue to be provided until the bandage 150 is removed.
Even in this case, a tip stimulation portion 112 is formed at the tip of the stimulation protrusion 111 in a planar shape, so that the stimulation protrusion 111 does not pierce the skin to be stimulated by the cosmetic acupuncture needle 100.

Fifth embodiment
Next, the fifth embodiment of the present invention will be described. The cosmetic acupuncture of this embodiment is almost the same as the configuration shown in the first embodiment, except for the shape of the handle. Therefore, the components almost the same as those of the first embodiment are given the same reference numerals and the description thereof will be omitted as appropriate.

FIG. 10 is a front view of cosmetic acupuncture according to the fifth embodiment.
As shown in FIG. 10 , the cosmetic acupuncture 100 has a connection hole 132 on the peripheral side of the end of the handle 130 for connecting to an accessory 200 .

The connecting hole 132 is a through hole that penetrates the peripheral end surface of the handle 130 in the radial direction. For example, by passing an accessory 200 such as a necklace chain through the connecting hole 132, the cosmetic acupuncture 100 and the accessory 200 can be connected.

This allows the cosmetic acupuncture 100 to be connected to the accessory 200 and worn by the user, improving the portability of the cosmetic acupuncture 100.
In addition, by hanging the cosmetic acupuncture 100, which is made of titanium alloy and stainless steel, forward from the user's neck via the accessory 200, the weight of the cosmetic acupuncture 100 can have the effect of improving the user's balance when walking.

In addition, a stimulation protrusion 111 or a protrusion for stimulating acupoints can be provided at the rear end of the handle 130. This allows the user to not only stimulate the skin in a planar manner using the roller portion 110, but also to stimulate partial acupoints using the stimulation protrusion 111 or a protrusion for stimulating acupoints at the rear end of the handle 130.

As described above, the cosmetic acupuncture 100 is capable of stimulating the skin without piercing it because the tip stimulating section 112 at the tip of the stimulating protrusion 111 is formed as a flat surface with a cross-sectional width of about one hair. Also, the stimulating protrusion 111 is long enough to reach the subcutaneous tissue, so the stimulating protrusion 111 can stimulate the subcutaneous tissue, which is the next structure after the epidermis and dermis that make up the skin, without piercing it.

It is known that the titanium alloy that forms the roller part 110 and stimulation protrusions 111 of the cosmetic acupuncture 100 can produce more than 100 different colors by changing the thickness of the oxide film that forms on the surface.

Specifically, part of the light traveling to titanium is reflected by the surface of the oxide film, while the rest enters the oxide film and is reflected by the surface of the titanium alloy before exiting. The phase of the light reflected by the surface of the oxide film and the light reflected by the surface of the titanium alloy interferes with each other, emphasizing the light and making it appear as a color.
The color of the roller portion 110 and the stimulation protrusions 111 can be changed by utilizing the change in color caused by the thickness of the oxide film formed on the surface.

In this way, the color of the roller portion 110 and the stimulation protrusions 111 can be changed depending on the height of the stimulation protrusions 111 to make them easier to identify, or the roller portion 110 and the stimulation protrusions 111 can be manufactured in a variety of colors.
