Description

Apparatus for improving human skin

The present invention relates to an apparatus for improving skin using electrical energy, and in particular, may be used as a direct and auxiliary means of skin shaping, in particular in cases where the primary purpose is to treat skin for beauty.

More particularly, the present invention relates to elastic treatment of skin using high frequency, and direct and sure skin improvement by minimizing skin aging by directly transmitting high frequency current to the dermal layer between the epidermal layer and subcutaneous fat layer of the skin. It relates to a skin treatment method and apparatus using a high frequency that can be made.

In general, the skin is the largest protection organ of the human body covering the whole body. Thus, the skin covering the whole body is composed of three layers of epidermal layer, dermis layer and subcutaneous fat layer to maintain surface homeostasis. do.

The dermal layer is located below the epidermal layer and is directly connected to the basal layer, and most of the skin is composed of the dermis, and protein, sugars, mucopolysaccharides, minerals, inorganic salts, and the like are in a jelly state, and the dermal layer is the epidermal layer. The papilla layer where capillaries related to blood circulation and lymphatic vessels carrying lymph are located while providing nutrition to the blood circulation, collagen which is related to wrinkles of the skin, and elastin and substrate which are elastic fibers that give skin elasticity It is composed of a network layer composed of). The subcutaneous fat layer is located between the dermis, muscle, and bone and contains a large amount of fat and constitutes the lowest layer of the skin.

As a typical skin treatment method for preventing aging of the skin, a method of massaging using a beneficial substance containing nutrients to the skin is most widely used. However, such a massage method of skin treatment provides nutrients to the epidermal layer of the skin to make the epidermal layer smooth, but it does not last long, and the improvement effect is rare in a short time.

Therefore, the newly appeared method was to inject cosmetic liquid into the skin using a syringe, but this method not only takes a lot of cost according to the procedure, but also causes a lot of side effects depending on the physical characteristics of people, and thus adversely affects the skin. Problems have arisen.

Since then, the high frequency method is indirectly delivered from the epidermal layer of the skin to the dermis. However, this is not only because the high voltage is used as it passes through the epidermal layer to the dermal layer, but it does not have a great effect, and it has a problem that it is cumbersome and costly to be continuously performed to obtain the effect.

Afterwards, the method of stimulating collagen regeneration by injuring the dermal layer was devised as a method of improving the skin. As one of such methods, a needle (which is also referred to as acupuncture in the present invention) is inserted into the dermis layer. Electrical stimulation has been devised.

In more detail, the dermal layer is composed of a protein called collagen, which is a triple helix structure containing fibroblasts and polypeptides, and the physical variation of the protein matrix at the temperature at which collagen tissues contract when heated. Will happen. One of these variations, soft tissue remodeling, is a phenomenon that occurs at the cellular and molecular level, and is caused by contraction caused by artificial heat or partial denaturation of collagen, which breaks the triple helix bonds and destroys the intermolecular bonds of the matrix do. When cell contraction occurs, collagen is located underneath as a static support matrix in the tightened soft tissue structure. Deposition and subsequent remodeling of the initial scar matrix provides a means of altering the consistency and shape of the soft tissue for cosmetic purposes. Soft tissue remodeling is an immediate process when compared to the contraction as a result of the movement of fibroblasts into the wound and natural wound healing. As a result, the treatment for cosmetic purposes such as skin improvement or wrinkle improvement can be said to begin by applying various energy sources to the site to coagulate the tissue.

When energy is applied to the dermal layer of the skin, the shape affecting the dermis depends on the amount of energy injected. Generally, carbonization, vaporization, and coagulation are performed. Divided. The skin improvement device of the present invention is a method of improving skin by forming a double coagulation state in principle, which can be expressed as "burns", "heats", "cooks", etc. There is a side that can not be called. However, in the present invention, the expression "learning" still represents the meaning of "applying energy in principle to make the state of coagulation" relatively, so that the expression "learning" in principle makes the state of coagulation by applying energy. " Is used in the sense.

The term "learning" described in the detailed description may be stronger than that of applying energy, but the term "learning" described in the patent claims of the present invention is particularly meant to apply energy to make it solidify in principle. Was used.

In this regard, there is a patent application 2000-0058346. The present invention was made for the purpose of restoring wrinkles to a flat state, the original shape of the skin, by checking the thickness of the wrinkles, the degree of indentation, the length of the wrinkles, the shape, etc. After setting the wattage of the elevation current in which the tissue is expanded, specifying the pulse and time, determine the length of the needle according to the length and the degree of the pleat, and attaching the needle to the handpiece. It is configured to be removed.

The patented technique, although saliva, did not fully express its principle, was a very dangerous initial step, especially for real human application. Therefore, a number of patents are further advanced, which is representative Patent No. 10-0856736 filed and registered by the inventor of the present invention. In particular, the present invention penetrates several dozens of needles into the skin at the same time, so that several kinds of needles simultaneously touch the skin, which forms a surface contact shape, which is an important occasion for increasing the effectiveness of skin treatment. .

Another recent similar technique is Korean Patent Application No. 10-2009-23494. In more detail, the present invention relates to elasticity of the skin using high frequency. More specifically, high frequency is directly transmitted to the dermal layer between the epidermal layer and the subcutaneous fat layer of the skin to activate cell tissues to maintain elastic skin. This is to minimize aging. The skin treatment apparatus is connected to the main body case into which a pair of electrode rods are inserted, and fixed to the connection portion through which the high frequency current is energized. It relates to a method and apparatus for skin treatment using a high frequency, characterized in that composed of several high frequency generating terminals inserted into the layer to generate a high frequency current.

However, this method of skin treatment is effective by directly applying energy to the dermis layer compared to the method of using conventional massage, laser, or even high frequency, so that it can be effective within a short time. Was effective. But there were many side effects.

The biggest side effect is that the epidermal layer as well as the epidermal layer between the saliva is cooked, and the epidermal layer is damaged, and the skin is excessively cooked and damaged so that the skin cannot be returned.

If only the dermal layer is properly cooked, it appears as a coagulation phenomenon and promotes collagen regeneration.However, when the epidermal layer is cooked by the above method, the area becomes a scar, and the action for skin improvement is greater. There was a tendency to call.

This phenomenon of ripening both the dermal and epidermal layers between the needles is a natural phenomenon from the viewpoint of those skilled in the art so that electric energy passes between the needles serving as electrodes and the skin between them has a much lower resistance than air. It has been given a constant resistance, but it was accepted that such resistance generated heat in all parts of the skin between the saliva, and in fact it appeared.

Another problem was that the procedure was very difficult to fine tune. This is because, as described above, when both saliva and saliva are ripe, the form is also quite rapid. Therefore, it was very difficult to divide the treatment several times according to the condition of the skin tissue, which is a serious problem that brings many limitations in terms of safety in terms of medical equipment.

So most of the techniques have since been applied with an insulating coating except for the tips of the needles that reach the dermis. But this also caused many problems.

First coating, the thickness of the needle naturally became a little thick, which caused problems. If only a typical problem is heard, the traces of roughness can be left large and may cause more pain when penetrating, and the likelihood of occurrence of side effects that the insulation coating is not in harmony with the human body.

The second problem is that the coated part is always likely to peel off. Because it is a natural equipment to apply high frequency and continuously penetrate the instrument. If the coating is peeled off, there is a high possibility that it will cause more side effects than when used carefully without the first coating.

Third, because it is a radical device that learns between the still and non-isolated needles, fine tuning is difficult and there is a possibility of overcooking.

Another conventional technique is a device that imparts electrical stimulation by penetrating a monopolar. The monopolar imparts one polarity to the device that touches the skin to be treated and the opposite polarity is applied to other sites unrelated to the treatment. However, in order to have an effective effect with this method, there was a fatal weakness that required high-flow electricity to generate heat. As a result, there is a risk of burn as well as the possibility that the applied current always affects organs such as the heart.

The present invention has been made in the course of studying and studying these problems in various ways.

The problem to be solved by the present invention is a number of problems mentioned in the prior art.

Skin improvement device according to an embodiment of the present invention is unlike the skin ripening form known in the art in the conventional bipolar electrode at all the epidermis is hardly cooked as shown in the drawing, mainly in the vicinity of the dermis around the tip of the saliva It can be learned to distinguish the ripe skin area from the rest of the skin in the form of a bulb.

In addition, the skin improvement device according to an embodiment of the present invention is significantly different from the prior art in that, unlike the prior art, it has a space to learn independently for each needle without learning all the areas between the needles without insulation coating. . In addition, it has been invented on the basis of numerous trials and errors and experiments for many years, and the effect thereof has the effect of significantly improving the problems of the prior art.

In addition, unlike the prior art, the skin improvement device according to an embodiment of the present invention does not learn the area between the electrodes, but learns each of them separately based on the ends of individual electrodes. It is a breakthrough technology that can be finely divided by the method. In other words, by adjusting the intensity as a whole, a large number of treatments are needed, and a small number of treatments are required, and a small number of treatments are performed.

In addition, the skin improvement device according to an embodiment of the present invention has a significant difference from the prior art in that the epidermis is hardly ripe and can be cooked by focusing only on the intended dermis, so that the needle is not insulated coated. Due to this, it is possible to completely solve the problem of insulation coating, which is the most fatal problem of the prior art. In principle, the treatment method of the present invention is judged that the saliva portion penetrating the skin does not need to be insulated except in special cases.

Sometimes the application of the present invention, even if the operation in somewhat harsh conditions only need to coat a very narrow part of the contact with the epidermis, such a case is just in case and generally need not.

The electricity supplied for the present invention is in the form of alternating current, the electrical energy may be configured in the form of high frequency.

In addition, the bipolar electrode system may be configured between the needles inserted into the skin or the support portion and the needles supported on the skin without being inserted into the skin.

In addition, the spacing between the needles inserted into the skin may be adjusted to prevent the ripening areas concentrated on the electrode ends from sticking to each other.

There is a difference from the trend of the prior art that the needle should not be coated in the present invention. This does not mean that the coating is not possible at all, but it is no longer necessary to do what was necessary in the prior art. .

In addition, the skin improvement device according to an embodiment of the present invention can be arranged to form a net-shaped surface when the end of the needle to the end of the needle. For this purpose, theoretically, the number of needles should be 4 or more, but preferably, if it is assumed to be at least a square, it can be said that the number of needles on one side is 4 or more.

In addition, the skin improvement apparatus according to an embodiment of the present invention may be arranged as shown in FIG. 7 to apply an alternating current to a plurality of needles, but different polarities of + and − between neighboring needles.

Skin improvement apparatus according to another embodiment of the present invention is a needle having a sharp end, the support portion surrounding the needle, the needle fixing portion for fixing the needle and the support and the electrical connection with the needle and the support is electrically And an electrical energy transfer unit for supplying energy, wherein the needle and the support unit form one module for transmitting energy, and the support unit includes a plurality of modules, and the support unit is supported by contacting the upper part of the skin, and at the same time, the needle Inserted into the skin, the supplied electricity is in the form of an alternating current, the electrical energy is in the form of a high frequency, the needle and the support is made of bipolar electrode system of different polarity, and is transmitted through the support and the needle By the electric energy is learned to learn the periphery of the end of the needle included in each of the plurality of modules, ripe skin area The rest of the skin area so that you can learn to distinguish.

In addition, the support may be characterized in that the cylindrical or polygonal shape.

In addition, the bipolar electrode body may be characterized in that the polarity between the needle and the support is composed of + and-or-and +.

In addition, the plurality of needles may be characterized in that the spacing of the nearest branch to each needle is 1.3 to 3mm.

In addition, the alternating current is 20Hz or more, the voltage applied to the plurality of needles may be characterized in that 100V or less, the time applied to the plurality of needles is 0.05 to 0.8 seconds.

In addition, the thickness of the saliva may be 0.25mm to 0.3mm, the length of the saliva to be inserted into the skin may be characterized in that 0.1mm-5mm.

The greatest effect of the present invention is that it can solve the fatal problem of the prior art.

First, the major side effect of the prior art is that both the dermal layer and the epidermal layer between the saliva and the excessively cooked the skin is damaged so that irreversible irreversible points occur when using the skin improvement device according to the present invention All can be solved.

In the skin improvement device according to the present invention, unlike the form of ripening the skin at the bipolar electrode, which has been conventionally recognized, the epidermis is hardly cooked as shown in FIG. It can be learned to distinguish the area from the rest of the skin area. Therefore, it can be finely adjusted by adjusting the intensity of various elements of electricity or by adjusting the spacing, or it is a groundbreaking method that can be divided by weakening the strength from the beginning. In other words, by adjusting the intensity as a whole, a large number of treatments are needed, and a small number of treatments are needed, and a small number of treatments are performed. . In medical terms, this is a breakthrough.

In addition, in the prior art, the epidermal layer ripens and the ripened areas become scars, and the measures for skin improvement tend to cause more skin damage. As shown in FIG. 6, the epidermal layer ripens hardly occurs, which is also an important effect. One.

Therefore, since most of the techniques have been performed by applying an insulating coating except for the tips of the needles that reach the dermis, the present invention is that the coating can not learn the skin around the tip of the needle as desired As a result, the thickness of the needle that can occur when the insulation coating is naturally thickened, leaving a large amount of traces of roughness, increasing the pain and causing the coating to peel off at all times. It can be remarkably solved.

The present invention has been experimented through various embodiments based on the contents presented above, and based on the contents, it will be summarized in detail centering on the components here.

Electricity supplied to the skin improvement device according to an embodiment of the present invention may be a bipolar and daily AC current but use high frequency.

In addition, while the skin improvement device according to an embodiment of the present invention to learn the end of the saliva, the spacing between the electrodes is important in order to learn to distinguish the ripe skin region and the remaining skin region. This is because, if the spacing between the electrodes is too narrow, the ripening areas concentrated at the ends of the electrodes may stick together.

An alternating current (AC) is a current that periodically changes in magnitude and direction over time, usually expressed in alternating current (AC). Sine waves are the most typical and can be transformed into square waves or triangle waves. The direction of current flow is different from the constant direct current. In general, the alternating current is used in each country by unifying the frequency of 50Hz or 60Hz.

It is determined that the alternating current supplied through the skin improvement device according to the embodiment of the present invention will not be a problem unless the frequency is particularly high, for example, several hundred Hz. Even if the frequency is considerably high, the needle spacing can be reduced to offset the effects. However, low frequency seems to be a problem. In this case, if the frequency is 20Hz or more, other factors may be adjusted so that the skin region ripening around the tip of the saliva and the remaining skin region can be learned. The adjustment of other factors will be described later.

In addition, it was examined and tested in various ways, but at least not high frequency, the ripening effect was not realized to distinguish the skin around the saliva. For example, low frequencies, as well as other methods such as ultrasound, medium frequency, and ions have not been implemented properly.

In particular, the ripened skin region and the remaining skin region were learned to be distinguished from the high frequency at 0.5 MHz or more. Among them, the most preferable case is currently used at about 2 MHz. In other words, the range is preferably 0.5-10 MHz, more preferably 1-4 MHz, and most preferably 1.5-2.5 MHz. However, depending on the given conditions, it is expected to be slightly different, but in general, it is not far from the above range.

In detail, the electrical conductance test using dry and wet skin using 2 MHz and 1 MHz showed 0.037102 at 2 MHz and 0.013237 at 1 MHz for dry skin, and 0.26649 and 1 MHz at 2 MHz for wet skin. Eg 0.2214. Eventually, it can be seen that the RF energy flow is smoother at 2 MHz. In conclusion, when the same energy is applied in dry skin, the probability of sparking at 1 MHz can be changed by other variables, but only by arithmetic comparison It's about three times higher.

Theoretically, when the frequency is higher, the higher frequency forms an energy region only in a relatively close vicinity when flowing the same current, while the lower frequency forms an energy region far from the electrode.

For example, in the case of 0.5 MHz or less, even if the distance between the electrodes is too large, the energy range is too wide, causing burns to the epidermis, which may cause scars, especially when treating thin skin such as eyelids that require precise treatment for narrow areas. You can also give

Above 10MHz, the energy range is so narrow that the treatment time is long and it is difficult to create an energy region for optimal treatment.

Skin improvement device according to an embodiment of the present invention can adjust the spacing of the saliva according to the treatment site, the nature of the electricity applied. For example, in relation to the frequency of high frequency, when the high frequency frequency increases, the spacing of the needles decreases, and when the high frequency frequency decreases, the interval between the needles (or sometimes referred to as "needles") may increase.

In the case of 2 MHz, the interval between the needles was about 2 mm. This will be described in more detail later.

Next, the needle of the skin improvement device according to an embodiment of the present invention does not necessarily require an insulation coating. In principle, near the epidermis is hardly ripe, and as shown in FIG. 6 around the tip of the needle that has dug into the dermis, the ripened skin region and ripened to distinguish the remaining skin region similar to the bulb shape do not need insulation coating. However, the coating itself alone cannot impede the performance of the skin improvement device of the present invention unless it is intended for electrical insulation. For example, in order to enhance the strength of the needle, there was a case of not affecting the effects of the present invention, such as coating due to metal coating or heat treatment, which does not affect insulation.

In other words, in order to make the best use of the skin improvement device according to an embodiment of the present invention, it is preferable not to insulate, and in other words, it means that at least the dermis section is preferably not coated with insulation. However, insulation does not impair the effects of the present invention. For example, if the part except the tip of the needle is coated with insulation, it may have a ripe portion similar to that of using monopolar, but the shape is the same, and it may be called a completely different effect originating from a significantly different mode of action.

Next, the skin improvement apparatus according to the exemplary embodiment of the present invention may configure the arrangement of the polarity of the needle, that is, the electrode as shown in FIG. 7. This arrangement consists of a collection of squares and needles arranged at each orthogonal point, meaning that the polarity of one needle is different from the polarity of the needle at the nearest neighboring point. Since the supplied electricity uses an alternating current, the polarity changes about 50 to 60 times per second, even with a single needle. Even so, of course, it is possible to apply an alternating current to the needle, that is, every minute, as shown in FIG. 7 so that the polarities of neighboring needles are different from each other. In the skin improvement device according to an embodiment of the present invention, the polarities of the needles are arranged in such a manner as to intersect in each direction with (+) and (-) so as to be different from the polarities of the neighboring needles. do.

Of course, a square gathering is generally desirable, but it can be a set of slightly inclined rhombuses, and even if it is a set of rectangular or slightly inclined sides with different lengths, the same effect of different polarization of neighboring needles It confirmed that it generate | occur | produced. In some cases, non-electric saliva can be placed in several places, or the presence of saliva can be intentionally subtracted in one place. However, the arrangement of the polarity of the needle is, in principle, meaning that it is included in the technical scope of the present invention if it is arranged while crossing each other in (+) and (-) directions so as to be different from the polarity of the nearest neighboring needles. have. In the present invention, the term "principally" expressed in relation to the polar arrangement of the needle is used in the sense of including the above cases.

In addition, while designing the product, it is inevitable to mix the above various shapes, in order to configure the skin improvement device according to an embodiment of the present invention, in principle, the polarity of the needles adjacent to each other in the arrangement of the electrodes as described above You can set up various cases that contain a significant amount of things that are different.

Here, a considerable part may be an example in which electrodes of a predetermined region are intentionally arranged as described above in order to construct a skin improvement apparatus according to an embodiment of the present invention.

9 to 11, the skin improvement device according to an embodiment of the present invention may include a needle 300, a support part 1000, and a needle fixing part 100.

The needles 300 each have a sharp end, and the support portion 1000 has a shape that surrounds the needle 300 from the outside and its shape may be in the form of a cylinder or a polygonal column.

The needle 300 and the support part 1000 are fixed to the needle fixing part 100, and may be electrically connected to the needle 300 and the support part 1000 by an electric energy transmission unit (not shown) to supply electric energy. .

As described above with reference to FIGS. 6 and 7, the plurality of needles arranged in the needle fixing unit are arranged to cross (+) or (-) so as to have a bipolar electrode system. The skin improvement apparatus of FIGS. 9 to 11 may use the needle 300 as the negative electrode and the support part 1000 as the positive electrode, or the opposite electrode body.

The support part 1000 is in contact with the skin to support the skin improvement device, and the needle 300 is inserted into the skin to transmit electrical energy to the skin.

The plurality of needles 300 and the support part 1000 may form one module for transmitting electrical energy and may include a plurality of modules in the support part 100, and the procedure is performed through the plurality of needles 300 described above. The same effect can be obtained.

In addition, the support portion 1000 is provided with a plurality of pieces, the shape of the pieces may be configured in the form of enclosing the outside of the needle 300 in a straight line, U-shaped or V-shaped.

12 and 13, the shape of the support part 1000 may be configured into a plurality of pieces by adding a portion to be cut at a predetermined interval to the circular arc portion of the cylinder. In addition, the plurality of disconnected pieces each have an electrode opposite to the plurality of needles 300.

The shape of the support part 1000 is not necessarily limited to the shape of a cylinder, and when applied in the form of a polygonal column, a plurality of pieces are formed by adding a part that is similarly cut off at the middle part of the corner or the part where the corner meets the corner. can do.

In addition, referring to FIGS. 15 and 16, the shape of the support part 1000 may be arranged in the vertical direction of the needle 300 in the vertical direction.

In addition, referring to FIG. 14, a flow path portion 303 through which a material that can be injected into the skin may be added for medical or therapeutic purposes of the skin in the longitudinal direction of the saliva 300. It can operate on a principle similar to a syringe for injecting injections into blood vessels of the body. In the saliva fixing part 100, a container (not shown) for storing a substance to be injected into the skin may be disposed to inject the material into the skin at a pressure set by the flow path 303 through the saliva fixing part 100. .

Although the voltage of the electricity supplied to the skin improvement apparatus according to the embodiment of the present invention is an important factor in determining the saliva spacing, it may also be directly related to the safety of the device. Therefore, it is usually desirable to measure the voltage applied to the skin.

Therefore, the meaning of "voltage applied to the skin" and the possibility of the measurement are as follows.

The actual voltage applied to the skin is the voltage applied between the skin part and the surface of the specific part of the needle (acupuncture) inserted into the skin. Therefore, unlike the voltage applied to the device, it can vary depending on the sum of three resistance values, namely, device resistance, positive resistance, and skin resistance. It may also be the same or different at every site of the saliva surface inserted into the skin. Because the resistance value of the skin part in contact with the needle surface of the specific site may be different, even if the same voltage is applied on the entire surface of the needle, the skin applied voltage of each site may be different.

However, since the resistance value in the skin is different but not a big difference, in the present invention, the measurement was made based on the voltage value measured on the surface of the saliva while the saliva was inserted into the skin and expressed as a voltage value.

This is a component directly related to the amount of energy applied, and it is undesirable to exceed a maximum of 100V. The preferred voltage was 10-60V and the optimum voltage was tested at 20-40V. Of course, even if it exceeds 100V, the ripening effect may be exhibited so as to distinguish the periphery of the needle tip by the skin improvement device of the present invention. Therefore, it may be desirable to use 100V in some severe situations.However, for example, if the voltage is applied to 100V, the ripening effect may occur, but a scar may occur. Difficult to do However, if we can eliminate the problems such as scars by introducing various conditions such as shortening the application time as much as possible, it will be possible to use it even at over 100V.

The voltage (skin voltage) applied to the skin of the human body during the procedure may be designed to vary in accordance with the voltage (external voltage) and circuit design set in the device, which can be easily implemented by those skilled in the art as Since it is not a characteristic component, detailed description is omitted.

Another variable is current. However, since this changes according to the voltage and resistance value, it can be calculated when the voltage, device resistance, electrode (needle) resistance, and skin resistance value applied through the equipment are determined.

V = I * R

Resistance values are largely divided into three resistance values, namely, device resistance, electrode resistance, and skin resistance.

Another important component is energy duration. Looking at the minimum time, it takes about 0.02 seconds to reach the stable region of high frequency energy, so if the energy duration is too short, the effect is almost unmeasurable. Measurements showed that it should be at least 0.05 seconds. The main feature of the present invention is that the energy duration is relatively short, but the longest time that the effect appears is 0.8 seconds. Of course, longer time intervals and minimal voltages would be possible, but still, if the optimal conditions were possible at this point, the range could be 0.05 to 0.8 seconds.

However, the preferable time is 0.1 to 0.4 seconds, and the most preferable time is 0.1 to 0.2 seconds. Finding this time was much more difficult than it was supposed to be, repeated a lot of trial and error, and required a lot of foresight. The reason why the application time is shortened while using a high frequency and using a low voltage while using alternating current is that such a short application time can be imagined only after creating the skin improvement device of the present invention.

Compared to the fact that the electric application time of the present invention is compared with the fact that the device that does not penetrate the skin with the actual saliva but stimulates the skin with the electrode (formerly Polaris device) gave energy for more than 0.5 seconds even at a much higher voltage. It can be seen that the device of the invention is a device that adds energy for a much shorter time.

Next, the skin improvement device according to the embodiment of the present invention should consider the length and thickness of the saliva. Needle thickness affects the spacing between needles. It must also be inserted into and out of the skin repeatedly, so it must be capable of withstanding without bending in the process. The thicker it is, the greater the pain, the greater the puncture and the greater the bleeding.

In conclusion, the thickness of the saliva should be minimized to minimize pain, and the saliva should not bend, and the appropriate range should be found to minimize the wound. Currently, clinically used needle thicknesses of 0.25mm and 0.3mm are considered acceptable.

The length of the needle may vary depending on the design of the device, so it is difficult to speak uniformly. However, when talking about the length inserted into the skin, there is no big problem to mention uniformly according to the thickness of the skin and the purpose of the procedure.

In this regard, the depth of the skin is summarized in FIG. 1, which can be determined based on this. Normally the epidermis is between 0.2mm and 1mm and the dermis is between 1mm and 4mm. Therefore, at least 0.2mm should be at least to reach the dermis, and the maximum length to reach the end of the dermis may be 5mm, so the preferred depth for treatment is 1mm - 5mm considering safety. Therefore, the total length of the saliva may vary depending on the type of device, but the length of the saliva to be inserted into the skin is preferably 1mm-5mm.

One of the parts to be most concerned with in order to design a skin improvement device according to an embodiment of the present invention is the interval between saliva as described above. Although there are various methods of measuring the spacing, the description will be made based on the closest spacing between the skin of a specific needle and the skin of an adjacent needle as shown in FIG. 8. In the present invention, the spacing between the needles is defined in this manner.

By the skin improvement device according to an embodiment of the present invention, the interval at which the ripening area is ripe to distinguish the remaining area from the ripened area of the saliva is possible up to 1.3 mm. Therefore, although the preferable gap is observed at the level of 1.3 to 3.0 mm, it is considered that it is possible to use a method of reducing the amount of the applied current or the resistance even at a wider interval.

In addition, even in a skin improvement device including a plurality of modules including the needle 300 and the support part 1000, the same may be applied to the interval from the needle included in any one module to the needle of the closest module. have.

However, the spacing between the needles can vary slightly with many variables.

Looking at the factors affecting the interval between the saliva of the skin improvement device according to an embodiment of the present invention.

First, when power (= energy) increases or the thickness of the needle becomes thick, the interval between the needles should be increased. When the power is divided, the power is multiplied by the voltage, the current, and the application time. Therefore, the interval between the needles should be increased if any one or more values of voltage, current, application time, needle thickness, and conductivity increase.

However, if one or more values of resistance, alternating frequency, high frequency frequency, or depth of penetration into the skin increase, the effect of learning to distinguish the periphery of the tip of the needle even if the interval between the needles is narrowed down a little more There may be no effect on the occurrence.

If this is expressed as formula, it is as follows.

N: proportional constant

Resistance: device resistance, electrode resistance, skin resistance (only skin resistance is used when considered in skin)

Since the power (= energy) is J = W * t (W = power, t = time)

= V * I * t (W = V * I)

= I ^ 2 * R * t (V = I * R)

therefore,

It can also be expressed as.

In the present invention, the needle fixing part is a component, where the fixing means that the needles do not scatter freely anywhere, but it does not limit the movement of the needle in the fixing part and is not a characteristic component of the present invention. .
