The present invention relates to a microneedle roller, and more particularly, to a cosmetic or drug delivery through the skin tissue and used to heal the skin tissue, and more particularly to a microneedle roller for improving the circulating effect and skin penetration. .

In general, the delivery of cosmetics or drugs through the skin is very low absorption rate because the drug is difficult to penetrate the stratum corneum. In particular, when the molecular weight is large, the water absorption becomes even lower. To improve this, a technique using a microneedle (also called a microneedle) has been proposed. The microneedles are used to form new channels that pass through some or all of the epidermal layer, and deliver the drug through or through the channels to the epidermal or underlying layer. According to this technology, even large molecular weight drugs such as insulin and hormones can be easily delivered through the skin. In addition, when microneedles penetrate and stimulate the dermis, burns and scars can be cured naturally. In addition, collagen production may be induced to maximize skin tone improvement and anti-aging effects.

Microneedle rollers are currently used as channel forming means by microneedles. The microneedle roller is a structure in which the microneedle protrudes from the surface of the roller head in a cylindrical roller head. As the roller head rotates, the microneedles form many channels in the skin at once. Examples of microneedle rollers are described in PCT WO / 0,247,555, PCT WO / 0,249,711 and the like.

However, such a conventional micro needle roller is composed of a micro needle stainless steel (stainless steel) material. And since the microneedle comes from the inside of the roller head, there is a limited space to place the pin inside the roller head. Therefore, there is a limit in reducing the spacing between microneedles. Usually the needle spacing is about 2 mm in a straight line distance. It is difficult to maximize the therapeutic effect by narrowing the gap between the needles. It is also cumbersome to require disinfection for repeated use. It is also made of stainless steel, which increases the price.

As another technique, as in Korean Utility Model Registration No. 115807, “Skin Scratches for Drug Administration”, a structure in which an intermediate material is interposed between circular skin needle plates and ten to hundreds of skin needle plates and intermediate materials are introduced. . However, this technique has a problem in mass production due to the complicated manufacturing process. For example, there are difficulties in the process due to the constraint that the skin needle plates must be displaced from each other. Therefore, it cannot be manufactured by going through a one shot process and has a disadvantage in that the process time is long.

On the other hand, in order to overcome such a problem, the applicant has filed a 'polymer micro needle roller and its molding die' of the application number 10-2006-0061788 dated July 3, 2006.

The technique disclosed in the above application has the advantage of providing a microneedle roller that is simple in structure and short in processing time and can significantly reduce manufacturing costs and is capable of mass production. However, vibration and vibration can be used to activate skin tissue or promote blood circulation. The user's convenience technology such as infrared emission has not been developed.
