Description

Device for dosing medicine through the skin}

The present invention relates to a skin drug injector, and more particularly, to a skin drug injector to continuously supply a certain amount of drug to the skin stimulus by pressing the drug supply unit at a constant force and speed with a simple configuration.

In general, by stimulating the skin of the human body with sharp needles, the epidermal layer of the human body is not damaged, but the natural skin is reduced by induction of natural healing collagen production such as laser peeling or peeling, especially when the needles penetrate the skin. By reorganizing and rearranging the tissue, minimizing hair follicle rupture, preventing skin deformation and cell necrosis, stimulating the dermal layer of the skin, restoring collagen synthesis, skin damage and spreading wrinkles have been proposed and used. This situation is becoming.

In other words, the corium related to wrinkles constitutes the lowermost layer of the epidermis, and is composed of a layer several times thicker than the epidermis with a thickness of about 0.7 mm to 4 mm, and the amount of collagen in the dermis gradually decreases as the aging progresses. Is dried and wrinkles are stretched.

Therefore, in order to slow the progress of skin aging or to improve or prevent wrinkles, it is necessary to continuously replenish the consumed collagen or inject new collagen, and conventionally apply nutrients such as vitamin C and peptides necessary for collagen formation to the skin, The rooting method was mainly used.

However, as described above, the method of applying or spraying nutrients such as vitamin C and peptides on the skin, when passing through the stratum corneum, 99.7% does not pass through the outermost sebum and remains on the skin and disappears. There was an inefficient problem where only% was used.

In order to solve the above-mentioned problems in recent years, microchannels are made on the skin by stimulating the skin using sharp needles to supply the nutrients necessary for collagen formation such as vitamin C and peptides to the dermis or to effectively regenerate collagen in the dermis. Skin stimulator (aka microneedle) that can be used has been proposed and used.

In this prior art, Korean Patent Publication No. 10-1103558 and Republic of Korea Patent Publication No. 10-2011-0138685 and the like are stamped using a microneedle, such components are simply applied to the skin using a microneedle It is configured to induce skin regeneration by forming micropores to infiltrate drugs, which makes it difficult to exert additional irritation on the skin or effectively prevent skin damage that may be caused by microneedles.

In addition, the prior art has a disadvantage that it is cumbersome to use the drug separately applied to the skin and the effect of healing and skin improvement of the skin tissue is limited.

Korean Patent Publication No. 10-1520942 discloses a drug injection device as a conventional technology for solving such a problem, which is a body part, a drug supply unit which is bound to the body part and supplies a drug, and the body part It is characterized in that it is configured in the injection unit is installed in the injection portion for injecting the drug supplied from the drug supply to the skin, there is a disadvantage that can not control the injection rate and injection amount of the drug.
