Description

주사장치{INJECTION DEVICE}INJECTION DEVICE

본 발명은 주사장치에 관한 것으로, 더욱 상세하게는 약액병에 직접 결합될 수 있고, 피부에 터치함과 동시에 약액이 주사바늘을 통해 피부에 주입되도록 하는 주사장치에 관한 것이다.The present invention relates to a scanning device, and more particularly, to a scanning device which can be directly coupled to a chemical solution bottle, and allows a chemical solution to be injected into the skin through a needle upon touching the skin.

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 procedure (hereinafter, referred to as a "multi-hole procedure") in which a plurality of minute holes are drilled in the skin and a drug or the like is injected into the body eliminates various skin troubles such as wrinkles, stains, dullness, stretch marks, acne, freckles, , Maintaining hair health, improving hair loss, and is being widely applied to treat 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.Such a multi-hole procedure can achieve a quick surgical effect by allowing the new skin to grow using the self-sustaining force of the damaged skin tissue, or allowing drugs and the like to penetrate into the body through the fine holes.

인체의 피부는 표피층(epidermis), 진피층(dermis) 및 지방조직층(fat layer)으로 크게 구분될 수 있다. 상기와 같이 구분되는 각층에서 피부의 상당 부분을 차지하고 있는 진피층은 유두층과 망상층으로 구성된다. The human skin can be roughly divided into the epidermis, the dermis, and the fat layer. The dermis layer, which occupies a large part of the skin in each layer separated as described above, is composed of the papillary layer and the reticular layer.

유두층에는 모세혈관 및 림프관 등이 배치되어 있고, 망상층에는 피부의 주름과 관련된 교원섬유인 콜라겐, 피부에 탄력성을 부여하는 탄력섬유인 엘라스틴 및 기질 등이 포함된다.Capillary blood vessels and lymph vessels are arranged in the papillary layer. Collagen, collagen fibers related to the wrinkles of the skin, elastin and the elastic fibers, which give elasticity to the skin, are included in the reticular layer.

이와 같이 피부의 시각적인 상태는 진피층의 건강상태에 따라 크게 좌우되므로, 피부의 상태개선을 위하여 시행되는 다양한 방법들은 진피층을 대상으로 하는 경우가 대부분이다.Since the visual state of the skin greatly depends on the health condition of the dermal layer, various methods for improving the condition of the skin are mostly applied to the dermal layer.

진피층은 상술한 바와 같이 표피층에 의해 보호되고 있으므로 진피층에 전달하고자 하는 약물을 피부에 도포하더라도 진피층까지 도달되는 양과 속도는 현저히 저하되는 경우가 많다.Since the dermal layer is protected by the skin layer as described above, even when the drug to be delivered to the dermal layer is applied to the skin, the amount and speed reaching the dermal layer are often significantly lowered.

이에 표피층에 도포된 약물이 진피층에 신속히 전달되도록 하기 위하여 압력이나 초음파진동을 가하는 방안이 제안된 바 있다. In order to rapidly transfer the drug coated on the skin layer to the dermal layer, a method of applying pressure or ultrasonic vibration has been proposed.

이는 표피층을 손상시키지 않는다는 장점은 있으나, 목적하는 압력이나 초음파진동을 발생시키는 수단을 구비하기 위하여 비용이 상승되고 체적의 증가되는 단점이 있다.This has the advantage of not damaging the skin layer, but it has disadvantages that the cost is increased and the volume is increased in order to provide a means for generating a desired pressure or ultrasonic vibration.

이러한 단점을 극복하고자, 미세한 바늘(이하, '니들(needle)'이라고 함)로 표피층에 통공을 형성한 다음 목적하는 효과를 갖는 약물을 피부에 도포함으로써 약물이 진피층에 전달되도록 하는 방안이 널리 사용되고 있다.In order to overcome such disadvantages, a method of forming a through hole in a skin layer with fine needles (hereinafter referred to as a " needle ") and then applying a drug having a desired effect to the skin to deliver the drug to the dermal layer is widely used have.

At this time, the chemical liquid enters the pressure member 4 through the through hole 421 again.

이후 다시 약액통(100)을 손으로 누르면 가압부재(4)가 도 5와 같이 상방으로 팽창되면서 가압부재(4) 내의 약액이 니들(7)을 통해 토출된 후 손을 떼면 원래 상태로 회복되는 과정을 반복하면서 약액의 주입과 중단이 연속 반복될 수 있다. Thereafter, when the chemical solution bottle 100 is manually pressed, the pressure member 4 is expanded upward as shown in FIG. 5, and the chemical solution in the pressure member 4 is discharged through the needle 7, The injection and the interruption of the chemical solution can be repeated continuously while repeating the process.

니들(7')이 한방침인 경우 도 6에 나타낸 바와 같이, 한방침이 피부(200)를 천공한 후 가압부재(4)에 고여있던 약액이 니들허브(6)의 막음판(64)의 홀(642)을 통해 안내캡(8)의 내부에 유입된 후 니들(7')이 관통된 통로(660)와 니들결합관(84)를 통과하여 피부에 도포될 수 있고, 피부(200)에 도포되었던 약액이 피부(200)의 천공에 의해 피하층으로 유입될 수 있다. 6, when the one needle is pierced through the skin 200, the chemical solution accumulated in the pressing member 4 is pushed out of the blocking plate 64 of the needle hub 6 Can be applied to the skin through the passage 660 and the needle coupling pipe 84 through which the needle 7 'penetrates after being introduced into the guide cap 8 through the hole 642, The drug solution applied to the skin 200 can be introduced into the subcutaneous layer by perforation of the skin 200.
