Description

Stamp needle assembly {STAMP TYPE NEEDLE ASSEMBLY}

The present invention relates to a needle assembly, and more particularly, to a needle assembly that can be injected into the skin irritation or irritation or through the punctured hole in the skin.

Skin can be divided into epidermis, dermis and subcutaneous tissue.

The epidermis covers the outermost part of the body, and prevents the invasion of foreign substances and prevents water decay in the body. The epidermis can be divided into stratum corneum, transparent layer, granule layer, polar layer, and basal layer.

Here, the stratum corneum is made up of 20% moisture, but the stratum corneum is generally separated from the skin, but as the skin ages, the stratum corneum does not fall well, resulting in a dull face or poor makeup.

The thickness of the dermis is about 2mm on average, and the dermis contains collagen, elastin, hyaluronic acid, NaPCA, and the like. When these ingredients are damaged by UV rays, aging of the skin proceeds.

As such, the collagen contained in the dermis gradually decreases as the aging progresses, resulting in dry and wrinkled skin, and continual supplementation of collagen or new collagen to prevent wrinkles or maintain elastic skin. It is necessary to inject.

Conventionally, in order to prevent wrinkles or elastic skin, a method of applying or spraying nutrients such as vitamin C and peptides necessary for collagen formation has been applied to the skin. In fact, there was a disadvantage that the effect was not great.

In order to solve this problem, a method using a device commonly referred to as a 'microneedle' has been introduced.

The microneedle is a device that stimulates the skin by using a needle of a small size, or provides a small hole in the skin to supply nutrients necessary for collagen formation to the dermal layer and to facilitate the penetration of drugs.

According to such microneedles, even high molecular weight drugs such as insulin and hormonal agents can be easily delivered through the skin.If the needle penetrates into the dermis and stimulates, burns and scars can be naturally cured, and collagen production is induced. The skin tone improvement and anti-aging effect can also be expected. Due to this efficacy, various types of microneedles have been introduced.

Korean Patent No. 10-0803020 discloses a 'needle roller manufacturing method', and specifically, vitamin C, peptide, etc. by stimulating the skin or forming microchannels in the skin tissue using the microneedle coupled to the roller.
