[0032] Hereinafter, the most preferred embodiment of the present invention will be described in detail to enable a person having ordinary skill in the art to easily carry out the present invention.

[0033] The numbers cited in the examples below are not limited to the referenced objects and can be applied to all examples. Objects that achieve the same purpose and effect as the configurations presented in the examples are equivalent replacement objects. The superordinate concepts presented in the examples include subordinate concepts not described.

[0034]

[0035] (Example 1-1) The present invention relates to a multi-needle for drug injection, comprising: an injection unit (100) to which a drug syringe (10) storing a drug is coupled and through which the drug is injected by pressure; a needle coupling unit (200) coupled to the front of the injection unit (100) and to which a plurality of needles (20) penetrating the skin are coupled; a suction unit (300) into which the needle coupling unit (200) is inserted and which suctions air at a location where it comes into contact with the skin; and a temperature control unit (400) formed on the front of the suction unit (300) and which controls temperature.

[0036] (Example 1-2) The multi-needle for drug injection of the present invention includes, in Example 1-1, the drug syringe (10) formed as a syringe in which a drug is stored.

[0037] (Example 1-3) The multi-needle for drug injection of the present invention includes, in Example 1-2, the needle (20) protruding outward from the temperature control unit (400) and inserted into the skin.

[0038] (Example 1-4) The multi-needle for drug injection of the present invention includes, in Example 1-3, the injection part (100) in which the drug is discharged through a plurality of needles (20) by the pressure of the drug syringe (10).

[0039] (Example 1-5) The multi-needle for drug injection of the present invention includes, in Example 1-4, the temperature control unit (400) formed of a metal material having high thermal conductivity.

[0040] The present invention relates to a multi-needle for drug injection, and more specifically, the multi-needle for drug injection is for injecting drugs into the skin. Such a multi-needle for drug injection is formed by protruding a plurality of needles (20) by combining a drug syringe (10) containing the drug to inject the drug into the skin. Generally, medical devices using multi-needles include a water light syringe for injecting a specific drug into the skin and a high-frequency multi-needle treatment device for applying high-frequency waves into the skin. At this time, the water light syringe is a medical device that uses a multi-needle composed of 3*3 or 4*4 needles to inject a specific drug into the subcutaneous layer at a certain depth, and injects the drug subcutaneously through the central cavity of each needle. In addition, as a method for inserting multiple needles into the skin by passing through the resistance of the skin, an air suction device is installed at the tip of the multi-needle to pull the skin toward the needles so that the skin is inserted into the needles.

[0041] Furthermore, high-frequency multi-needle therapy devices use multi-needles connected to a high-frequency generator to generate numerous microscopic tissue coagulations at a specific depth under the skin. When high-frequency waves are applied to the needles inserted into the skin, Joule heating occurs in the subcutaneous tissue. This heat-induced microscopic tissue coagulation (coagulation) induces tissue damage (electrothermal damage) and triggers the body's natural wound healing process. This increases collagen and elastin in the skin and reduces minor wounds and wrinkles, resulting in smoother, more youthful skin. Fractional Radio Frequency Microneedling devices, designed to artificially generate numerous microscopic tissue damages, have multiple needles attached to a single surface, arranged in 7x7 or 9x9 configurations. These medical devices inject high-frequency waves into the skin through each needle, raising the temperature around the needles to over 42°C, thereby generating microscopic tissue coagulations in the subcutaneous layer around the needles. The multi-needles used in these water light syringes and high-frequency multi-needle therapy devices are painful when inserted into the skin or injected, which can be unpleasant for the recipient. Furthermore, temperature control of the treatment area is necessary to enhance the effectiveness of high-frequency multi-needle or drug-injecting multi-needle treatments.

[0042] On the other hand, referring to FIGS. 1 and 2, the multi-needle for drug injection of the present invention is formed as a syringe and a drug syringe (10) storing the drug is connected, and an injection part (100) in which the drug is injected by pressure is connected to the front of the injection part (100), a needle connection part (200) in which a plurality of needles (20) that penetrate the skin are connected, and the needle connection part (200) is inserted inside, and a suction part (300) that sucks in air at a location where the skin is in contact with the skin and a temperature control part (400) that is formed on the front of the suction part (300) and controls the temperature are formed. At this time, the needle (20) protrudes outward from the temperature control part (400), so that the needle (20) is inserted into the skin and the temperature of the surface of the skin is controlled to reduce pain and increase the hemostasis effect. In addition, as the drug syringe (10) is connected to the injection part (100), the drug stored inside the drug syringe (10) is discharged through the needle (20). In addition, the suction unit (300) can insert the needle (20) to an accurate depth by sucking air to form a vacuum at the location in contact with the skin, and the temperature control unit (400) can control the surface temperature in contact with the skin to reduce pain.

[0043] Therefore, the multi-needle for drug injection of the present invention has the characteristics of being formed by vacuum while controlling the surface temperature in contact with the skin, thereby reducing pain and injecting the drug at an accurate depth.

[0058] And the injection case (110) is attached to the rear of the needle coupling part (200). This is to prevent the drug from leaking out by the needle coupling part (200) and the injection case (110) being attached to each other, thereby allowing the drug to be smoothly distributed to the distribution groove (112).

[0059]

[0060] (Example 4-1) The present invention relates to a multi-needle for drug injection, and in Example 3-1, it includes a coupling case (210) formed on the needle coupling part (200) and to which the injection part (100) is coupled; and a fixing member (220) protruding from the front of the coupling case (210) and to which the needle (20) is fixed.

[0066]

[0067] (Example 5-1) The present invention relates to a multi-needle for drug injection, and in Example 4-1, it includes: a suction case (310) formed on the suction part (300) and having the needle coupling part (200) housed therein; a fixing projection (320) protruding from the front of the suction case (310) and through which the needle (20) passes;

[0072] The present invention relates to a suction unit (300), and specifically, the suction unit (300) has a needle coupling unit (200) housed inside, and is configured to adhere to the skin by sucking air in the front. Referring to FIGS. 5 and 6, the suction unit (300) is formed in the same shape as the needle coupling unit (200), and a suction case (310) is formed inside, in which the needle coupling unit (200) is housed.

[0073] Conventional methods of inserting multi-needles into the skin using a strong pressure device that pushes the multi-needles into the skin can cause fear and rejection in patients due to the pain caused by the strong pressure, the pain that occurs when multiple needles are inserted into the skin simultaneously, and the pain caused by the drug injection. Furthermore, when multiple needles are inserted by pulling the skin with vacuum pressure, each needle is inserted at an uneven depth depending on the skin condition and condition. As a result, some of the drug is not injected into the skin and may leak out because the needles are inserted at an inconsistent depth. To prevent this, deep needle insertion or strong vacuum pressure is applied, which causes great pain to the patient receiving the procedure.

[0074] On the other hand, the suction part (300) has a needle coupling part (200) accommodated in the receiving space (314) formed inside the suction case (310), and a suction space (311) formed on the front side to suck air between the fixing protrusions (320).

At this time, the temperature control unit (400) is formed with a control case (410) through which the coolant or fruit passes, and a control member (420) coupled to the front of the control case (410) is formed.

[0081] And the control case (410) is in close contact with the front of the suction part (300), and refrigerant control holes (411) are formed on both sides of the control case (410) so as to protrude outward and through which refrigerant or heat is introduced and discharged. In addition, the refrigerant control holes (411) are formed at positions facing each other, so that the refrigerant or heat introduced in one direction through the refrigerant control holes (411) is discharged through the refrigerant control holes (411) in the other direction. And the control member (420) formed on the front of the control case (410) is formed with a control plate (421) that comes into contact with the skin and a vacuum hole (422) that is formed at equal intervals on the control plate (421) and extends downward. At this time, the vacuum hole (422) is formed with a fixing protrusion (320) inserted therein, and the fixing protrusion (320) and the control plate (421) may be formed at the same position, or the position of the fixing protrusion (320) may be variable. In this way, as air is sucked from the suction part (300), the skin is pulled between the vacuum hole (422) and the fixing protrusion (320), and the needle (20) is effectively inserted into the skin.

[0082] And the temperature of the control plate (421) is controlled as the refrigerant or fruit moves. When the control plate (421) is cooled by the refrigerant, the pain when the needle (20) is inserted into the skin is reduced and hemostasis is achieved as the skin contracts. In addition, when the control plate (421) is warmed by the fruit, the effect can be maximized through thermal stimulation, such as collagen.

[0083] Accordingly, the temperature control unit (400) of the present invention has a feature that can reduce pain and increase the hemostatic effect by cooling or warming the needle (20) when it is inserted into the skin.
