Description
본 고안은 의료용 패치에 관한 것으로, 더욱 상세하게는 창상 밖으로부터 세균과 수분의 진입을 막고, 창상면으로부터 가스와 수증기의 투과를 일정하게 허용하여 창상주위피부가 물러지지 않고 창상면에 세균감염이 생기지 않도록 방어하며, 습윤환경을 유지시키기 위해 구비되는 커버 패치와, 피부 창상 부위에 직접 접촉되는 습윤보습용 드래징재의 접촉면 사이에 공기층이 형성되지 않도록 함으로써, 상기 커버 패치의 접착면에 부착되는 습윤보습용 폼드래싱과 환부와의 밀착성을 높이고, 상기 커버 패치의 피부 부착면이 작은 면적을 갖더라도 피부와의 접촉상태가 양호하게 유지될 수 있도록 구성되는 의료용 패치에 관한 것이다.The present invention relates to a medical patch, and more particularly, to prevent bacteria and moisture from entering the wound, and to allow a constant permeation of gas and water vapor from the wound surface, so that the bacterial infection on the wound surface does not recede. Wet to adhere to the adhesive surface of the cover patch by preventing the formation of an air layer between the cover patch provided to maintain the moist environment, and the contact surface of the wet moisturizing dragging material in direct contact with the skin wound site The present invention relates to a medical patch configured to increase the adhesion between the moisturizing foam dressing and the affected part, and to maintain a good contact state with the skin even if the skin attachment surface of the cover patch has a small area.
창상, 욕창, 화상, 하퇴궤양 등의 만성 난치성 피부궤양의 빠른 치료를 위한 습윤 보습환경의 습윤보습용 폼드래싱은, 피부 친화적인 소재와 우수한 효과를 갖는 약물의 개발에 따라 더욱 다양한 의료 분야에서 확대 적용되는 추세에 있다.Wet moisturizing foam dressings for the rapid treatment of chronic refractory skin ulcers such as wounds, bedsores, burns and lower ulcers are expanding in a wider range of medical fields with the development of skin-friendly materials and drugs with excellent effects. There is a trend to apply.
상기와 같은 의료용 패치 중에서도 최근 각광 받는 바이오테크놀로지의 기술 추세가 반영된 하나의 예로써 50~500㎛ 정도의 두께로 형성되어 수분의 진입을 막고 세균 및 이물질의 침투를 방지하는 외피층과, 평균직경 60㎛의 포어(pore)를 다수 포함하여 고 투습성, 고 흡수성을 갖게 하는 내부 흡수폼층과, 상처면 비 부착 특성을 갖게 하는 피부 접촉층으로 구성된 폼 드레싱재가 공지된 바, 환부로부터 나타나는 흡수 삼출액 중 상처 치유에 방해 요소로 작용되는 창상면으로부터의 가스와 수증기를 외부로 방출시키고, 상처 치유를 돕는 세포 성장인자 및 싸이토카인, 클라이코사미노클라이칸, 단백질 등의 외부 누출을 차단하여 농축시키는 방법에 의해 상처 치유 속도를 빠르게 하고, 치료 후 피부에 남게 되는 반흔을 최소화시킬 수 있도록 하였다.Out of the above medical patches as an example reflecting the recent trends in the emerging biotechnology technology is formed with a thickness of about 50 ~ 500㎛ thickness of the outer layer to prevent the ingress of moisture and infiltration of bacteria and foreign substances, and an average diameter of 60㎛ It is known that a foam dressing material is composed of an inner absorbent foam layer containing a large number of pores of pores and having a high moisture permeability and a high absorbency, and a skin contact layer having a non-adhesive property on the wound surface. Wound healing by releasing gas and water vapor from the wound surface acting as an interfering element to the outside and blocking and concentrating external growth of cell growth factors and cytokines, Klycosaminoglycans, and proteins that help wound healing The speed was increased and the scars remaining on the skin after treatment were minimized.
상기와 같은 습윤보습용 폼드래싱의 드레싱이라는 용어는 언제부터 사용되었는지 불분명하지만 어원상 "창상을 덮는다", "창상을 가린다"는 행위를 가리키는 말로써 사용되고 있다 "드레싱" 즉 창상을 덮는 것은 상당히 오래 전부터 그 개념과 용어가 일반적으로 존재해서 사용되어 진 것으로 보여 진다.While the term dressing of wet moisturizing foam dressing is unclear from when it was used, it is used to refer to the act of "covering the wound" and "covering the wound" in terms of "dressing" or covering the wound for a long time. The concept and terminology have been shown to exist and be used in the past.
선사, 고대, 그리스-로마, 중세에서 근세에 이르기까지 시대가 발전하고 의학이 개선되면서 드레싱은 창상 국소 관리의 독립된 기법분야로 분화 발달되고 있다. 이러한 형태의 발전은 건조 드레싱을 주류로 심화 발전되어 왔으나, 근래에 와서 건조드레싱을 대신하는 습윤 드레싱의 혁명적 이론의 발전은 몇 개의 중요 연구 결과에 의하여 발전되고 있다.Dressing has evolved into an independent technique of wound local care, with the development of medicine and the advancement of medicine from prehistoric, ancient, Greek-Roman, and medieval to modern times. While this type of development has been further developed into the mainstream of dry dressing, the development of the revolutionary theory of wet dressing instead of dry dressing has been developed by several important research results.
이는 1958년 Odland의 수포를 그대로 두는 것이 더 빨리 치유된다는 관찰 연구, 1962년 돼지를 대상으로 Polyethylene필름으로 덮어둔 경우가 건조시킨 가피의경우보다 상피화율이 두배나 좋았다는 Winter의 연구, Hinman과 Mainbach이 인체 피부에서 Winter의 결과를 확인한 연구, 1970년대초 Rovee가 습윤시킨 가피가 없는 환경이 상피세포의 창상부를 이동시키는 상피재생을 촉진시킨다는 연구이다.This is an observational study that leaving Odland's blisters healed faster in 1958, Winter's study that the epithelialization rate in pigs covered with polyethylene film in pigs in 1962 was twice as good as that of dried peels, Hinman and Mainbach. This study confirmed Winter's results on human skin, and said that a non-skin-free environment moistened by Rovee in the early 1970s promotes epithelial regeneration that shifts the epithelial cells' wounds.
개방 창상의 경우 상피세포 이동은 가피창에서 형성되는 콜라겐에 의해 억압되고 창상부액이 혈관 신생과 상피화를 자극하는 여러 성장인자(Growth factor)를 없앤다는 연구 결과들은 그들의 이론을 더욱 뒷받침하였다.In the case of open wounds, epithelial cell migration was suppressed by collagen formed in the epidermis, and the findings further corroborated their theory that the wound fluid eliminates many growth factors that stimulate angiogenesis and epithelialization.
이러한 습윤환경이론을 충족시키는 최초의 드레싱재로서 근대 드레싱의 제 1세대는 1971년 Smith & Nephew사(社)의 Opsite란 상품이 출시되었으며 이것은 Polyurethan필름과 vinylether, 점착제로 구성된 것으로 창상 밖으로부터 세균과 수분의 진입을 막고, 창상면으로부터 가스와 수증기의 투과를 일정하게 허용하여창상주위피부가 물러지지 않고 창상면에 세균감염이 생기지 않도록 방어하며 습윤환경을 유지시키는 반 투과성 필름드레싱이다.As the first dressing material to meet the theory of wet environment, the first generation of modern dressings was launched in 1971 by Opportunity, Smith & Nephew, which is composed of polyurethan film, vinylether and adhesive. It is a semi-permeable film dressing that prevents the ingress of moisture and allows the permeation of gas and water vapor from the wound surface to prevent the surrounding skin from repelling and to prevent bacterial infection on the wound surface and to maintain a wet environment.
이러한 이론을 근거로 출시된 Opsite는 습윤환경이론을 만족시키는 우수한 드레싱제로 널리 사용되었지만 그 성질과 점착성 등의 문제점들이 드러나기도 했다.Based on this theory, Opsite has been widely used as an excellent dressing agent that satisfies the theory of wet environment, but its problems such as its properties and tackiness were revealed.
다른 제조회사에서 소재필름의 개량과 점착제의 아크릴레이트로의 변경을 시도한 다양한 소재들을 개발하였으며 이러한 발전은 1970년대 소위 제 2세대의 드레싱제 들이 출현하였다.Other manufacturers have developed a variety of materials that have attempted to improve the material film and to change the pressure-sensitive adhesive into acrylates. This development led to the emergence of so-called second-generation dressings in the 1970s.
Convatec사(社)의 하이드로콜로이드(Hydrocolloid)재를 사용한 제품으로 하이드로콜로이드재는 친수성 폴리머를 주성분으로 하는 일련의 제품을 속칭하는 것으로 창상, 스토마(stoma) 및 실금 관리기구에 광범위하게 쓰이는 용어다.This product uses Convatec's Hydrocolloid material, which is a generic term for a series of products based on hydrophilic polymers and is widely used in wound, stoma, and incontinence management devices.
하이드로콜로이드재의 출현은 창상치유, 특히 욕창, 하퇴궤양 등의 만성 난치성 피부궤양의 치료에 획기적인 도움을 주었으며, 전술한 모든 내용들은 도서출판 고려의학사의 "새로운 창상치료" 에 상세히 소개되어 있다.The emergence of hydrocolloids has greatly helped in the treatment of wound healing, especially chronic intractable skin ulcers such as pressure sores and lower leg ulcers, all of which have been described in detail in "New Wound Treatments" of the Korean Medical Press.
도 1은 종래의 의료용 패치를 보여준다.1 shows a conventional medical patch.
도 1a 내지 도 1b에 도시된 바와 같이, 종래의 의료용 패치는 일측면에 피부 부착면(12)이 형성되는 커버 패치(10)와, 상기 커버 패치(10)에 부착되어 환부(42)로 약물이 투여될 수 있도록 구비되는 습윤보습용 폼드래싱(20)이 포함되어 창상, 욕창, 화상등의 외상 또는 피부트러블에 따른 상처에 의한 환부(42)를 치료할 수 있도록 구성된다.As shown in Figure 1a to Figure 1b, the conventional medical patch is a cover patch 10 is formed with a skin attachment surface 12 on one side, and the cover patch 10 is attached to the drug to the affected part 42 The wet moisturizing foam dressing 20 is provided to be administered is configured to treat wounds 42 due to trauma or skin problems such as wounds, bedsores, burns.
상기 커버 패치(10)는 상기 습윤보습용 폼드래싱(20)과 피부(40)와의 밀착성을 유지시켜주는 역할 외에도 외부로부터 환부(42)에 악 영향을 주는 수분 또는 세균, 이물질 등을 차단시키는 역할과, 환부(42)로부터 발생되는 수분을 수증기 형태로 방출시키는 역할을 겸할 수 있어야 하며, 상기 습윤보습용 폼드래싱(20)은 환부(42)의 치료를 돕는 약물 성분을 다량으로 함유할 수 있도록 습윤성과 보습효과가 좋은 재질로 구성되어야 한다.The cover patch 10 serves to block moisture or bacteria, foreign matters and the like that adversely affect the affected part 42 from the outside in addition to maintaining adhesion between the wet moisturizing foam dressing 20 and the skin 40. And, it should be able to serve as a role of releasing the water generated from the affected part 42 in the form of water vapor, and the wet moisturizing foam dressing 20 to contain a large amount of drug components to help the treatment of the affected part 42 It should be composed of materials with good wettability and moisturizing effect.
그러나, 상기와 같이 구성되는 종래의 의료용 패치는, 궤양의 면적이 크거나 일반적인 창상과 비교하여 환부가 깊고 각종 삼출물의 분비도 매우 많이 발생되는 대규모 창상 즉, 욕창이나, 화상 등의 치료를 위해, 원할한 습윤 보습환경 및 많은 양의 삼출물을 충분히 흡수할 수 있고, 다량의 약물을 함유시켜 장시간 환부(42)를 치료해 줄 수 있도록 습윤보습용 폼드래싱(20)의 두께를 두껍게 하여 피부(40)에 부착시킬 경우, 커버 패치(10)와 피부(40) 사이에 빈 공간의 공기층이 형성되게 되므로, 피부(40)와의 안정적인 부착을 위해 커버 패치(10)의 부착면을 넓게 형성해야 했으므로 불필요한 부착부위가 커지게 되고, 상기 습윤보습용 폼드래싱(20)이 커버 패치(10)의 내측에서 유동될 가능성이 있어 환부(42)와 마찰에 의한 자극이 발생될 수 있으며, 보다 높은 점착력을 유지하기 위해 커버 패치(10)를 압박하여 환부에 접착하게 되면 접착강도만큼 환부가 압박되어 통증이 유발될 수 있고, 또한 피부(40)로부터 배출되는 땀 등과 같은 분비물이 상기 공기층 내부에 누적되는 상태로 유입되어 습윤보습용 폼드래싱(20)을 오염시킬 수 있으므로 환부(42)에 나쁜 영향을 줄 수 있다는 문제점이 있었다.However, the conventional medical patch is configured as described above for the treatment of large-scale wounds, such as bedsores and burns, in which the area of ulceration is large or the lesions are deeper and the secretion of various exudates is very high compared to general wounds. It can absorb the desired moist moisturizing environment and a large amount of exudate, and thickens the wet moisturizing foam dressing 20 so as to treat the affected part 42 for a long time by containing a large amount of the drug. In the case of attaching to the cover patch 10 and the skin 40, an empty air layer is formed between the cover patch 10 and the skin 40, so that the attachment surface of the cover patch 10 has to be formed wide for stable attachment with the skin 40. The area becomes large, and the wet moisturizing foam dressing 20 is likely to flow inside the cover patch 10, so that the friction with the affected part 42 may occur, and a higher point When the cover patch 10 is pressed to adhere to the affected area to maintain the attachment force, the affected part may be compressed by the adhesive strength, causing pain, and secretions such as sweat discharged from the skin 40 may accumulate inside the air layer. There was a problem that it may be introduced into the state to contaminate the wet moisturizing foam dressing (20) may adversely affect the affected part (42).
본 고안은 상기 전술한 문제점을 해소하고자 안출된 것으로서, 환부에 약물이 투여될 수 있도록 구비되는 습윤보습용 폼드래싱이 커버 패치에 형성되는 인입부 내부로 안착되어 커버 패치와 피부 사이의 접착부위에 불필요한 공기층이 형성되지 않도록 하는 구성으로, 상기 커버 패치에 비교적 작은 면적의 부착면 만을 형성하더라도 피부에 안정적으로 부착될 수 있고, 상기 습윤보습용 폼드래싱이 커버 패치의 내측에서 유동될 공간이 형성되지 아니하므로 습윤보습용 폼드레싱에 접촉되는 환부가 자극되지 않으며, 환부가 압박되어 고통을 가중시키지 않는 의료용 패치를 제공하는데 목적이 있다.The present invention has been made to solve the above-mentioned problems, the wet moisturizing foam dressing is provided in the affected part formed in the cover patch to be administered to the drug in the affected area to the adhesive site between the cover patch and the skin In such a configuration that unnecessary air layers are not formed, the cover patch can be stably attached to the skin even if only a relatively small area of the attachment surface is formed on the cover patch, and a space for the wet moisturizing foam dressing to flow inside the cover patch is not formed. Therefore, it is an object of the present invention to provide a medical patch that does not irritate the affected area in contact with the wet moisturizing form dressing and does not increase the pain due to the affected area.
