Description

Micro Needle Type Skin Stimulator

The present invention relates to a micro-needle type skin stimulator, and more particularly, by applying a needle piece which is provided integrally with a predetermined interval in the upper longitudinal direction, while maintaining the protrusion length to the tip of the microneedle at the same time. The microneedle is applied by applying a microneedle assembly in which the needle piece is tightly fixed between the first coupling block, the second coupling block, and the discharge guide block while increasing durability of the microneedle integrally provided at the top of the needle piece. It is possible to replace and use the needle piece integrally provided at the upper end, and the microneedle assembly is fixedly installed through the needle cover on the upper part of the discharge cap coupled with the main case containing the nutrient-containing fluid. Nutrients are transferred to the microchannel A microneedle type skin stimulator which can be supplied.

Generally, the dermis, which wrinkles the skin, constitutes the bottom layer of the epidermis, and is composed of a layer thicker than the epidermis with a thickness of about 0.7 mm to 4 mm.

In addition, the collagen in the dermis gradually decreases as the aging progresses, and as a result, the skin becomes dry and wrinkles increase.

Therefore, in order to prevent wrinkles and maintain elastic skin, it is necessary to generate collagen or inject new collagen.

However, when nutrients such as vitamin C or peptides required to form collagen are applied or sprayed on the skin, the amount of nutrients passing through the stratum corneum of the skin is only 0.3% of the total content, and the remaining 99.7% is the outermost sebum of the skin. It does not pass and remains on the skin or dries out.

Therefore, a microneedle therapy system is used to solve the above problems.

At this time, the microneedle therapy system as described above is a method of stimulating the skin using a roller protruding microneedle or by making microchannels on the skin to supply nutrients necessary for collagen formation to the dermal layer.

The epidermis of the skin is about 0.03 mm to 1 mm, and the protruding portion of the microneedle penetrates the epidermis and creates a microchannel leading to the dermis below the epidermis.

In other words, it is possible to effectively supply the skin with nutrients such as ingredients that make the skin elastic or prevent wrinkles through the microchannel formed as described above.

In addition, when the microneedle roller is used to make a fine wound on the skin, collagen is naturally generated by the natural healing power of the skin itself, so that the skin is regenerated.

In other words, it is possible to reduce aging skin by inducing natural healing collagen production such as laser peeling or peeling without damaging the epidermal layer.

It stimulates the skin through the microchannels as described above, and effectively supplies nutrients such as vitamin C and peptides to the dermal layer containing collagen to improve skin and wrinkles, as well as restore acne scars and burn scars. In order to treat the microneedle roller applied to one of the micro-needle type skin stimulator to form a micro channel on the skin is used.

1 and 2 is an exemplary view showing a micro needle roller applied to one of the micro-needle type skin stimulator according to the prior art.

1 and 2, the microneedle roller applied to one of the microneedle-type skin stimulators according to the prior art forms a radial groove 11 on one side of the plurality of disc disks 20, and then the needle 20. By inserting and stacking the disc 20 again, the needle 20 is configured to be embedded between the disc 20.

In addition, by inserting the roller shaft 30 in the center of the disc 20 to rotate the disc 20 using the handle 40 on the skin, the needle 20 stimulates the skin, The collagen component that is artificially supplied through the pores is to be easily supplied.

However, the microneedle roller applied to one of the microneedle-type skin stimulator according to the prior art as described above is fixed to the microneedle by closely coupling the elliptic disc after inserting the microneedle into the fine radial groove of the disc. At this time, since the needle inserted into the radial groove is not firmly coupled, the needle inserted into the radial groove may be separated during use.In case of excessive force, the needle is pushed to the rear side of the radial groove. Or the shape of the needle was deformed.

In addition, since the disc is combined with the needle and the handle is integral, when it is necessary to replace only the disc with the needle combined, it is difficult to replace only the disc, so the microneedle roller must be disposed of at the end. Accordingly, there was a problem that the replacement use is impossible.

In addition, the microneedle roller applied to one of the micro-needle type skin stimulator according to the prior art is merely for skin stimulation, and in order to supply additional nutrients on the skin stimulated by the needle, fluid containing separate nutrients is applied to the skin. There was inconvenience such as need to apply.

Therefore, the appearance of the needle portion is not deformed, and it is possible to replace and replace the lumbar component including the needle, while stimulating the skin and applying vitamin C to the dermis layer of the skin without applying a separate nutrient to the skin. There is a need for research and development of a microneedle-type skin stimulator that can stimulate the skin while easily supplying nutrients such as peptides and the like.
