Description

Medication dispenser

본 발명은 약품 투여기에 관한 것으로서, 더욱 상세하게는 인슐린에 전류를 공급하여 이를 이온화시키는 용기의 외주면에 접착부를 형성함으로써, 별도의 접착 테이프를 사용하지 않더라도 용기를 피부에 쉽게 부착할수 있는 약품 투여기에 관한 것이다.The present invention relates to a drug injector, and more particularly, by forming an adhesive portion on an outer circumferential surface of a container that supplies current to insulin and ionizes it, thereby to a drug injector that can easily attach the container to the skin without using an adhesive tape. It is about.

일반적으로 인슐린은 그 분자량이 6,000 이상의 거대한 분자로 구성되어 있으므로 화학적 용매를 사용하여 피부의 성질을 변형시켜 준다 하더라도 표피층의 투과가 불가능하며, 아미노산의 펩티드 결합체로서 친수성이 강한 약물이므로 소수성인 표피층과는 친화성이 양호하지 못하고, 이에 따라서 표피층을 투과할수 없어 피부내로 전달시키는 것이 불가능한 것으로 알려져 있는바, 근래에 들어서는 패치형의 인슐린을 피부를 통하여 혈액속으로 전달하는 경피투여방법이 연구 개발되고 있다.In general, insulin is composed of large molecules with molecular weight of 6,000 or more, so it is impossible to penetrate the epidermal layer even if chemical properties are used to modify the skin's properties. It is known that the affinity is not good, and thus it is impossible to transmit the epidermal layer to the skin. Therefore, a transdermal administration method for delivering a patch-type insulin into the blood through the skin has been recently developed.

그런데, 인체의 피부는 표피층, 경피층 및 진피층으로 구성되어 있고, 이들 구성요소중에서 약물전달이 가장 어려운 표피층은 20%의 지방질과 40%의 단백질로 구성되고, 그 두께는 0.1mm이상이며, 단백질의 각 세그멘트를 지방질이 둘러싸고 있는 구조를 가지고 있어 표피의 성질은 소수성을 띠고 있다. 그리고 진피층이나 경피층에서 함수율이 70% 이상인데 반해, 표피층의 함수율은 40%로 작기 때문에 전기적 저항이 크고 열적자극이나 외부의 자극으로부터 진피층을 보호하는 작용을 하는 것이다.By the way, the skin of the human body is composed of epidermal layer, transdermal layer and dermis layer, the most difficult drug delivery of these components is composed of 20% fat and 40% protein, the thickness is 0.1mm or more, protein Each segment has a structure surrounded by fat, so the epidermis is hydrophobic. In addition, the moisture content of the epidermal layer and the transdermal layer is 70% or more, whereas the moisture content of the epidermal layer is small (40%), so that the electrical resistance is large and protects the dermal layer from thermal stimulation or external stimulation.

이러한 경피 투여방법에 의한 종래의 인슐린 패치용 투여장치는 한국 특허공보 제 92-2264 호에 개시되어 있는데, 이는 패치몸체의 주요부를 이루는 인슐린 용매저장조와, 인슐린이 분말상으로 분사되어 있으면서, 수팽융성을 갖는 고분자 지지체와, 피부접착후 용매의 방출에 따라 팽윤거동을 나타내는 피부침 지지체와, 이 피부침 지지체에 수직으로 고정분포되어 피부와 접촉하게 되는 다수의 피부침 및 인슐린 용매저장조와 피부에 전기를 통전시킬수 있도록 인슐린 용매저장조의 상단 내부에 설치된 전극으로 구성되었다.A conventional insulin patch administration device by such a transdermal administration method is disclosed in Korean Patent Publication No. 92-2264, which is an insulin solvent reservoir forming a main part of a patch body, and while insulin is injected into a powder, water swellability It has a polymer support, a dermal needle support exhibiting swelling behavior in accordance with the release of the solvent after the skin adhesion, a number of dermal needles and insulin solvent reservoirs and fixed contact with the skin vertically distributed in contact with the skin It consists of an electrode installed inside the top of the insulin solvent reservoir so that it can be energized.

상기와 같은 종래의 인슐린 패치용 투여장치는 피부에 피부침 지지체의 피부침이 접촉되면 피부침으로 형성된 통로는 내부의 팽윤에 의해 일시적으로 닫혀지고, 인슐린 용매저장조 상단 내부의 전극에 직류 또는 맥류를 인가하여 주면 이온화된 인슐린과 용매들이 반대편 전극을 향하여 이동하게 되며, 이때 피부의 친수성 단백질과 폴리펩티드가 양극을 향하여 평행하게 배열되어 수축이 일어남으로써 표피층의 통로가 열려지게 되고, 통로속의 인슐린이 진피층으로 투여될수 가 있게 된다.In the conventional insulin patch administration device, when the skin needle of the skin needle supporter contacts the skin, the passage formed by the skin needle is temporarily closed by the swelling of the inside, and direct current or pulse flow to the electrode inside the upper end of the insulin solvent reservoir. When applied, the ionized insulin and solvents move toward the opposite electrode. At this time, the hydrophilic proteins and polypeptides of the skin are arranged in parallel toward the anode, causing the passage of the epidermal layer to open, and the insulin in the passage to the dermal layer. It can be administered.

그러나 이와 같은 인슐린 패치용 투여장치는 인슐린 저장용기와 피부침이 일체로 형성되어 있고 1회용으로서, 1회만 사용한 후 폐기처분해야 됨으로 수요자의 경제적인 부담을 가중시키게 되는 문제점이 있었다.However, such a device for administering an insulin patch has a problem in that an insulin reservoir and a dermal needle are integrally formed, and for one-time use, only one time of use should be disposed of and then disposed of.

이러한 문제점을 해결하기 위해서 본 출원인은 인슐린 패치와 피부침 구동장치를 별도로 제작한 형태의 인슐린 패치용 피부 전처리기를 다수개 안출한 바 있다. 이러한 피부침 전처리기는 단순히 인슐린을 투여하기 전에 피부에 다수의 흠집을 형성하는 것으로서, 피부 전처리후에 사용자는 인슐린을 피부에 투여하여야만 한다.In order to solve this problem, the present applicant has devised a plurality of insulin patch skin preprocessors of the insulin patch and the skin needle driving device separately. Such acupuncture pretreatment simply forms a plurality of scratches on the skin prior to administration of insulin, after which the user must administer insulin to the skin.

인슐린을 피부에 투여하는 투여기는 본 출원인이 국내 특허출원 제 94-11251호로 출원한 바 있다. 선출원된 투여기는 인슐린을 담는 용기와 인슐린에 전류를 공급하는 파워서플라이를 착탈 가능하게 결합 형성하고, 패치판과 인쇄회로기판과의 전기적 접속을 확실히 할수 있도록 한 것이다.The administering device for administering insulin to the skin has been filed by the applicant of Korean Patent Application No. 94-11251. The pre-applied injector is detachably coupled to the container containing the insulin and the power supply for supplying the current, and to ensure the electrical connection between the patch plate and the printed circuit board.

본 발명은 선출원된 투여기의 개선에 관한 것으로서, 본 발명의 목적은 인슐린을 이온화시켜 피부의 진피층으로 투여시키는 용기의 외주면에 접착부를 일체로 형성함으로써, 별도의 접착 테이프로 용기를 피부에 부착할 필요가 없어 사용이 편리하게되는 약품 투여기를 제공함에 있다.The present invention relates to the improvement of a pre-applied dispenser, and an object of the present invention is to form an adhesive portion integrally on the outer circumferential surface of a container for ionizing insulin to be administered to the dermal layer of the skin, thereby attaching the container to the skin with a separate adhesive tape. There is no need to provide a medicine dispenser that is convenient to use.

At this time, when the non-adhesive paper 19a is removed and the container 10 is attached to the skin using the adhesive part 19, the ionized insulin is in contact with the skin and the ground part 33 is contacted together to form a closed loop. Thus ionized insulin is administered to the dermal layer of the skin.

도 5는 본 발명 다른 실시예의 약품 투여기의 단면도 로서, 파워서플라이(30)가 끼워지는 요홈부(14)에 접지판(18)이 형성되어 접지부(33)와 피부를 연결시킨다. 접지판(18)은 도전성의 재질로 구성되며 요홈부(14)에 파워서플라이(30)가 끼워지면 이의 접지부(33)가 접지판(18)과 접촉된다. 따라서 용기(10)가 피부에 부착되면 접지판(18)을 통하여 접지부(33)와 인슐린이 폐루우프를 구성함으로 인슐린이 피부의 진피층으로 투여된다. 본 발명 다른 실시예는 요홈부(14)가 피부 쪽으로 노출되지 않으므로 파워서플라이를 보다 안전하게 사용할수 있다.Figure 5 is a cross-sectional view of the drug injector of another embodiment of the present invention, the ground plate 18 is formed in the groove portion 14 into which the power supply 30 is fitted to connect the ground portion 33 and the skin. The ground plate 18 is made of a conductive material. When the power supply 30 is inserted into the recess 14, the ground plate 33 is in contact with the ground plate 18. Therefore, when the container 10 is attached to the skin, the insulin is administered to the dermal layer of the skin by the ground plate 33 and the insulin forming a closed loop through the ground plate 18. According to another embodiment of the present invention, since the recess 14 is not exposed to the skin, the power supply can be used more safely.

이상에서와 같이 본 발명에 따르면 인슐린이 겔상태로 수용되는 용기가 얇은 슬림형으로 구성되며 또한 파워서플라이를 용기에 결합하여 전극판으로 전류를 공급하면 인슐린이 이온화된 상태로 피부의 진피층으로 투여됨으로 구성이 간소화 된다. 그리고 용기의 외주면에 접착부가 일체로 형성됨으로 용기를 피부에 부착하기 편리한 등의 효과가 있다.As described above, according to the present invention, a container in which insulin is contained in a gel state is formed in a thin slim type, and when a current is supplied to the electrode plate by combining the power supply with the container, insulin is ionized and administered to the dermal layer of the skin. This is simplified.
