일반적으로 피부에 다수의 미세한 홀을 천공하고 약물 등이 체내로 투입되도록 하는 시술법(이하 '멀티홀 시술법')은 주름, 기미, 잡티, 튼살, 여드름, 주근깨, 색소 침착 등과 같은 다양한 피부 트러블을 없애고, 두발 건강을 유지하며 탈모를 개선하고, 비만 치료에 적용하는 등 폭넓게 실시되고 있다.In general, a method of puncturing a lot of fine holes in the skin and injecting drugs into the body (hereinafter referred to as 'multi-hole procedure') removes various skin problems such as wrinkles, blemishes, blemishes, stretch marks, acne, freckles, and pigmentation. It is widely applied to maintain hair health, improve hair loss, and apply to the treatment of obesity.
이러한 멀티홀 시술법은 손상된 피부 조직의 자생력을 이용하여 새살이 돋도록 하거나, 미세한 홀을 통하여 약물 등이 체내로 침투되게 함으로써 빠른 시술 효과를 거둘 수 있다.The multi-hole treatment method can achieve a rapid treatment effect by using the viability of the damaged skin tissue to raise the new year, or by allowing the drug or the like to penetrate the body through the minute hole.
그러나 전술한 멀티홀 시술법은 시술자가 바늘을 피시술자의 피부에 일일이 꽂았다 빼는 동작을 반복하는 피시술자의 직관에 의하는 경우가 많았으므로, 피시술자가 고통을 호소하거나 일정한 깊이로 바늘이 주입되지 못하여 약물 침투 또한 균일하게 이루어지지 못하는 문제점이 있었다.However, in the multi-hole procedure described above, the operator often inserts and unplugs the needle into the skin of the subject, which is often caused by the intuition of the subject. There was a problem that can not be made uniformly.
또한, 전술한 멀티홀 시술법은 피부의 탄력이 저하되어가는 중장년층에게 시술할 경우 희망하는 깊이로 홀을 천공하고자 하여도 피부에 무수히 많은 미세한 홀을 천공하는 도중에 적절한 피부의 긴장도, 즉 텐션을 유지하지 못하는 경우가 있다.In addition, the above-described multi-hole treatment method does not maintain proper skin tension, that is, tension, while puncturing a lot of fine holes in the skin even when trying to puncture the hole to a desired depth when the procedure is performed to elderly people whose skin elasticity is deteriorated. You may not be able to.
즉, 전술한 멀티홀 시술법은 다수의 홀이 천공되는 과정에서 피부가 밀리고, 바늘 등의 시술 도구가 피부의 희망하는 위치에 정확하게 천공을 하지 못하고 미끄러지거나 바늘이 피부에 박힌 채로 밀리면서 피시술자에 통증을 유발시키는 등의 문제점이 발생하였다.That is, the above-described multi-hole procedure is the skin is pushed in the process of the puncture of a number of holes, the surgical tool such as the needle does not penetrate exactly to the desired position of the skin, slipping or pushing the needle stuck in the skin pain Problems such as causing a problem occurred.
한국 공개특허 제10-2010-0015018호는 "주사기용 석션어댑터"를 개시하고 있는데, 이에 따르면, 니들과 니들허브로 이루어진 주사기바늘에 결합되고 주사될 피부부위에 음압(suction)을 가할 수 있도록 공기흡입기에 연결하여 사용하는 것으로, 니들허브가 수용되는 제1공간부와, 니들허브에 결합되는 니들이 돌출될 수 있도록 제1공간부에 연통되는 관통공 및 상면이 개방된 제2공간부; 및 제2공간부와 연통되어 상기 공기흡입기와 연결되는 공기흡입기 연결부를 포함하도록 하고 있으며, 주사하고자 하는 부위에 석션어댑터에 밀착고정시키고 제2공간부의 공기를 공기흡입기로 흡입시킴으로써 주사장치 방향으로 피부층을 상승시켜 주사액을 주입함으로써 피부의 원하는 깊이에 주사액을 주입할 수 있게 된다.Korean Patent Laid-Open Publication No. 10-2010-0015018 discloses a "suction adapter for a syringe", which is coupled to a syringe needle consisting of a needle and a needle hub, and which allows air to apply a negative pressure to the skin area to be injected. A first space portion accommodating the needle hub and a second space portion having a through hole and an upper surface communicating with the first space portion to protrude the needle coupled to the needle hub; And an air inhaler connection portion connected to the air intake unit in communication with the second space part, and fixed to the suction adapter at the portion to be injected, and suctioning the air in the second space portion with the air intake unit to inject the skin layer toward the injection device.

아울러 한국 공개특허 제10-2010-0015018호는 멀티니들용 석션어댑터를 개시하며, 니들의 노출길이를 조절하기 위한 수단을 개시하고 있는데, 구체적으로 제2공간부의 상당부 및 돌출부의 높이가 니들의 노출분을 제외한 니들의 길이에 대응되도록 함으로써 니들의 노출길이를 고려한 멀티니들용 석션어댑터를 개시하고 있다.In addition, Korean Patent Laid-Open Publication No. 10-2010-0015018 discloses a suction adapter for a multi-needle, and discloses a means for adjusting the exposure length of a needle. Disclosed is a suction adapter for multi-needle in consideration of the exposure length of the needle by corresponding to the length of the needle excluding the exposure.
그러나 이러한 형태의 석션어댑터는, 석션어댑터 전방 단부로 니들이 노출되어 있으므로, 피시술자가 시술에 임하기 전부터 니들을 인식하게 되어 심리적 불안감을 느낄 수 있게 된다. 더욱이, 멀티니들의 경우, 다수의 니들이 한꺼번에 노출되어 있게 되므로, 피시술자가 느끼게 되는 심리적 불안감 또는 공포는 더욱 커지게 되며, 이에 따라 시술에 어려움을 격을 수 있다.However, in this type of suction adapter, since the needle is exposed to the front end of the suction adapter, the needle recognizes the needle even before the procedure is performed, and thus the psychological anxiety can be felt. Moreover, in the case of multi-needles, since a plurality of needles are exposed at once, the psychological anxiety or fear felt by the subject becomes greater, thereby making it difficult for the procedure.
또한, 상술한 바와 같은 형태의 석션어댑터를 사용하는 경우, 노출 길이를 조절할 수 있다고 하더라도, 하나의 석션어댑터를 사용하여 노출길이를 조절할 수는 없는 것이므로 실제로 '조절'의 개념은 아닌 것이고, 필요에 따라 개별 사이즈를 갖는 석션어댑터를 모두 구비하여야 하는 것이어서 석션어댑터를 일일이 교체하여야 하는 번거로움이 따르게 되는 문제점이 있다.In addition, in the case of using the suction adapter of the type described above, even if the exposure length can be adjusted, it is not a concept of 'adjustment' because it is not possible to adjust the exposure length by using one suction adapter. Accordingly, there is a problem in that it is necessary to provide all of the suction adapters having individual sizes, and thus, the trouble of having to replace the suction adapters individually is required.
