Description

메조테라피용 니들{Syringe needle for Mezotheraphy}Mesotherapy needles {Syringe needle for Mezotheraphy}

본 고안은 피하지방 분해용 주사기에 관한 것으로서, 더욱 상세하게는 주사기 허브 및 니들로 이루어진 통상의 주사기로서 니들의 길이가 3∼6㎜이고 니들의 외경이 0.27∼0.33㎜(31∼29G)인 메조테라피용 니들에 관한 것이다. 본 고안은 피부 밑의 중배엽(mesoderm)에 주사하는 메조테라피(mezotheraphy)용 니들에 관한 것이다.The present invention relates to a subcutaneous fat dissolving syringe, and more particularly, a mesozo having a needle length of 3 to 6 mm and a needle outer diameter of 0.27 to 0.33 mm (31 to 29 G). It is related to the therapy needle. The present invention relates to a needle for mezotheraphy injected into the mesoderm below the skin.

본 고안은 피부 하부의 중배엽에 적합 주사하여 지방 분해를 촉진하는 치료시 사용하는 주사기에 관한 것이다. 메조테라피 약물은 원칙적으로 전신 순환을 통해서 흡수되는 것이 아니라 병변이 있는 부위에만 작용하는 것이다. 메조테라피용 니들를 이용하는 방법으로서 기존의 주사기기를 사용하는 문제점은 현재 시판되는 종래의 제품은 주사기 니들의 길이가 13 ㎜ 밖에 없어 피하지방의 적절한 위치에 주사하기 어렵다는 문제점이 있다. 본 고안은 상기 문제점을 극복하기 위해 주사기 내 니들의 길이를 3 ㎜ 내지 6 ㎜로 하여 주사의 편리성, 신속성을 갖는 피하지방용 주사기의 개발에 관한 것이다.The present invention relates to a syringe for use in therapy that promotes lipolysis by injecting into the mesoderm below the skin. Mesotherapy drugs are not, in principle, absorbed through the systemic circulation, but act only on the site of the lesion. The problem of using a conventional syringe as a method of using a mesotherapy needle has a problem that it is difficult to inject into a proper position of subcutaneous fat because the conventional product currently available is only 13 mm in length. The present invention relates to the development of a subcutaneous fat syringe having the convenience and speed of injection with the needle length of 3 mm to 6 mm in order to overcome the above problems.

지방분해 효과가 있는 여러가지 약물을 피부에 직접 주사해 지방을 분해하는 방법은 프랑스에서 이미 50년 전부터 시술해온 방법이다. 비만크리닉의 시술방법인 메조테리피용 주사시술방법은 지방분해 효과가 있는 약물을 경구 복용하는 경우보다 투여량이 1/10 내지 1/60에 불과할 정도로 적은 양이며, 또한 주사기를 이용할 경우 치료하고자 하는 부위에만 적용하기 용이하므로 약물의 경구 투여보다 부작용이 적다는 것이 가장 큰 장점으로 작용한다. 또한, 메조테리피용 주사시술방법은 약물이 치료하고자 하는 부위에서 서서히 작용하므로서 1회 시술 후 효과가 1주일 정도 발효되는 장점이 있다.Decomposing fat by injecting a variety of lipolytic drugs directly into the skin has been performed in France for 50 years. Mesotherapeutic injection method, obesity clinic treatment method, is only about 1/10 to 1/60 less than oral dose of lipolytic drug, and the area to be treated by using syringe It is easy to apply only, so the side effect is less than oral administration of the drug is the biggest advantage. In addition, the injection method for mesotherapies has the advantage that the effect after the procedure is fermented for about a week because the drug acts slowly at the site to be treated.

메조테라피용 니들를 이용하는 방법은 메조건(mezo gun)을 사용하는 방법과 수작업으로 시술하는 방법으로 나뉜다. 메조건은 주사기 니들의 길이를 조절할 수있다는 장점이 있으나, 메조건의 기계적 특성 및 시술시 장갑을 착용함으로써 시술자의 민감도가 떨어지는 단점으로 인하여 얼굴 부위와 같이 섬세한 부분의 적용하기는 문제점이 있다.Mesotherapy needles are divided into methods using mezo guns and manual procedures. Me conditional has the advantage that the length of the syringe needle can be adjusted, but there is a problem in applying the delicate part such as the face part due to the disadvantage of the sensitivity of the operator by wearing the glove during the mechanical properties of the condition and the procedure.

메조테라피용 니들를 이용하는 방법으로서 수작업으로 시술하는 방법은 얼굴 등 섬세한 부위에 사용하기 적합한 방법이나, 현재까지 시판되는 메조세라피용 주사기의 니들부분의 길이가 13㎜ 내외로 수작업시 피하 4㎜ 내외의 지방층에 정확히 주사하기 위하여 숙련된 테크닉이 필요하다는 단점이 있다.The method of using mesotherapy needles is a method suitable for use on delicate areas such as the face, but the length of the needle portion of the mesotherapy syringes on the market is about 13 mm, and a subcutaneous fat layer of about 4 mm is used during manual operation. There is a disadvantage that skilled techniques are required to inject correctly.

본 고안은 종래 메조테라피용 니들의 문제점인 니들 부분의 길이가 16㎜ 내외로 시술시 적합한 4㎜ 내외의 지방층에 쉽고, 정확하게 주사할 수 없다는 문제점을 개선한 메조테라피용 니들를 개발하는 것이다.The present invention is to develop a needle for mesotherapy which improves the problem that the length of the needle portion, which is a problem of the conventional mesotherapy needle, is about 16 mm and can not be easily and accurately injected into a fat layer of about 4 mm suitable for the procedure.

본 고안은 주사기 허브 및 니들로 이루어진 통상의 주사기 니들에 있어서, 니들(12)의 길이가 3∼6㎜이고 니들(12)의 외경이 0.27∼0.33㎜(31∼29G)인 것을 특징으로 하는 메조테라피용 니들에 관한 것이다. 본 고안의 메조테라피용 니들은 길이(h)가 3∼6㎜인 메조테라피용 니들에 관한 것이며 상기 니들의 외경은 0.27∼0.33㎜(31∼29G)인 것이 바람직하다. 상기 니들의 외경 단위(G)는 게이지(gauge)이다. 주사기가 끼워지는 허브의 규격은 국제 규격으로서 전세계 모든 국가가 통일된규격이다.The present invention is a meso, characterized in that, in a conventional syringe needle consisting of a syringe hub and a needle, the length of the needle 12 is 3 to 6 mm and the outer diameter of the needle 12 is 0.27 to 0.33 mm (31 to 29 G). It is related to the therapy needle. The mesotherapy needle of the present invention relates to a mesotherapy needle having a length h of 3 to 6 mm, and the outer diameter of the needle is preferably 0.27 to 0.33 mm (31 to 29 G). The outer diameter unit G of the needle is a gauge. The specification of the hub in which the syringe is inserted is an international standard, which is a universal standard for all countries of the world.

본 고안의 메조테라피용 니들은 니들의 길이(h)가 3∼6㎜이고 니들의 길이가 4㎜인 것이 바람직하다. 본 고안의 메조테라피용 니들에서 니들의 길이가 3㎜ 이하인 경우는 피부 밑의 중배엽 까지 니들이 접촉되지 않기 때문에 메조테라피용 니들로서 기능을 하지 못한다. 또한 본 고안의 메조테라피용 니들에서 니들의 길이가 6㎜ 이상인 경우는 피부 밑의 중배엽을 초과하여 주사시 잘못하면 주사기의 니들이 혈관을 건드리는 부작용이 생길 염려가 있어 메조테라피용 니들로서 기능을 하지 못한다.The mesotherapy needle of the present invention preferably has a needle length h of 3 to 6 mm and a needle length of 4 mm. In the mesotherapy needle of the present invention, when the needle length is 3 mm or less, the needle does not function to the mesoderm below the skin and thus does not function as a mesotherapy needle. In addition, in the mesotherapy needle of the present invention, if the needle length is 6 mm or more, the needle of the syringe may cause a side effect of touching the blood vessel if the needle is inadvertently exceeded, so that it does not function as a mesotherapy needle. .

본 고안의 메조테라피용 니들은 니들의 외경이 0.27∼0.33㎜(31∼29G)이고 니들의 외경이 0.3㎜(29G)인 것이 바람직하다. 본 고안의 메조테라피용 니들에서 니들의 외경이 0.27㎜(31G) 이하인 경우는 약물이 통과하는 니들의 외경이 너무 좁아 약물이 막히거나 니들이 구부러지는 경우가 있어 메조테라피용 니들로서 기능을 하지 못한다. 또한 본 고안의 메조테라피용 니들에서 니들의 외경이 0.33㎜(29G) 이상인 경우는 주사하는 약물의 양이 너무 많이 주사될 수 있는 문제점이 있다.The mesotherapy needle of the present invention preferably has an outer diameter of the needle of 0.27-0.33 mm (31-29 G) and an outer diameter of the needle of 0.3 mm (29 G). In the mesotherapy needle of the present invention, when the outer diameter of the needle is 0.27 mm (31 G) or less, the outer diameter of the needle through which the drug passes is too narrow, so that the drug may be blocked or the needle may be bent, thus not functioning as a mesotherapy needle. In addition, when the outer diameter of the needle in the mesotherapy needle of the present invention is more than 0.33mm (29G) there is a problem that the amount of drug to be injected can be injected too much.

본 고안의 구조를 갖는 메조테라피용 니들의 작용을 기존의 주사기와 대비하여 보다 상세하게 설명하면 다음과 같다.The action of the needle for mesotherapy having the structure of the present invention is described in more detail in comparison with a conventional syringe as follows.
