Description

[0001] The present invention relates to a cartridge-type liquid injection device for skin treatment,

The present invention relates to a cartridge-type dermal drug injection device, and more particularly, to a cartridge-type dermal drug injection device that reciprocates a drug receiving cartridge having a plurality of needles so that a drug can be injected into the skin, Lt; / RTI >

In general, a skin treatment method for treating skin is a treatment method for skin beauty and hair health, obesity treatment and the like such as wrinkles, acne removal, exfoliation and hair loss treatment, and the like. Using a fine needle, A method of maximizing the drug efficacy by allowing a drug to be injected into the perforated skin surface after the hole is made and a method of regenerating the skin by stimulating the skin surface by using a needle to induce the self- It is mainly used.

In addition, the skin consists largely of the epidermis, the dermis, and the subcutaneous fat layer. The skin layer is the outermost surface of the skin. It consists of several layers such as stratum corneum, transparent layer and granular layer depending on position and function. .

The dermal layer is located below the epidermal layer, and includes proteins, carbohydrates, minerals and inorganic salts including water.

Particularly, collagen related to the wrinkles of the skin and elastin fibers which give elasticity of the skin are also located in the dermal layer.

On the other hand, since the characteristics of skin are different for each person, it is necessary to manage the skin after grasping individual skin characteristics in advance. As described above, when a stimulus is given to the skin using needles, a natural wound healing action As a number of microscopic needles penetrate into the skin, the dermis is reorganized and rearranged, so that the scar becomes shallow, the skin is pulled tight and the fine wrinkles are reduced and the pigmentation is improved to return to healthy, clean skin .

For example, by making a plurality of fine holes in the skin of a human body, it is possible to make new skin by using the self-sustaining force of the damaged skin tissue in the process of making fine holes, applying a therapeutic drug to a site where fine holes are formed, Allows penetration through the hole quickly into the skin. In addition, it generates deep heat by the high frequency in the needle, thereby increasing the temperature of the tissue, thereby improving the function of the cell and increasing the blood flow. Thus, the metabolism is enhanced, the deep pain is relieved, And various cosmetic effects such as anti-aging of skin, freckles of dandruff, burning of body fat, treatment of hair loss, and prevention.

In addition, since the drugs used in the multi-hole procedure usually have to be injected precisely several times in small quantities for a specific purpose, uniform and precise effects can be obtained throughout the entire skin. Thus, in the conventional manual inefficient method, A drug injection device is used.

Particularly, a drug injecting device for skin treatment is disclosed in Korean Patent Application No. 10-2010-0106297, which is conventionally used as a drug injecting device. However, since there is only one injection needle inserted into the skin, It is difficult to repeatedly perform multiple repetitive movements in a short time due to the structural characteristic of reciprocating the piston part of the syringe. Therefore, the multi-hole operation technique in which the drug is injected into the skin several times in small amounts And it was troublesome to correctly bind the syringe to the piston of the syringe when the medication was used depending on the site during the procedure.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to simplify the structure of a motion switching means constituting a drug injecting device for injecting a drug while repeatedly stimulating the skin, The drug can be more quickly and efficiently infiltrated into the site where the drug is to be injected into the user's skin and the drug to be injected can be easily changed and used as needed. The object of the present invention is to provide a drug injection device.

The present invention provides a drug injector for injecting a drug into a skin by inserting a needle into a skin to inject a drug, the drug injector comprising: a body having a depression with one side opened and having a space formed therein; And a through hole through which the motion switching means is coupled to the other side is formed on the other side of the driving motor, The slider housing includes a slider housing vertically movably coupled to the depression, a first elastic means provided at the depression for providing a vertical elastic force to the slider housing, and a drug injection cartridge detachably attached to the opening.

The motion switching means includes a cam formed on a driving shaft of the driving motor, a vertical moving member contacting the cam, and a second elastic member providing a vertical elastic force to the vertical moving member.

In addition, a guide groove is formed on the inner circumferential surface of the body, and the movement switching means is movable along the guide groove. The drive motor is disposed between the drive motor and the slider housing. And a fixed housing which is fixed to the housing.

The present invention provides a drug injection device for a skin type skin, which comprises a cam which is directly coupled to a driving shaft of a driving motor, and a motion switching means composed of a vertical moving member which contacts the cam, The reciprocating motion cycle of the cartridge can be controlled, and the drug cartridge can be easily detached and attached. Thus, when the skin drug is required to be replaced, the drug can be used more quickly.
