폴리우레탄폼시트(1), 연고약제(2), 투명이형지(3).Polyurethane foam sheet (1), ointment (2), transparent release paper (3).
본 고안은 창상, 화상, 욕창 등의 상처를 입은 피부에 사용되며 폴리우레탄폼 시트의 상부에 다양한 무늬와 다양한 형태의 연고 약제가 구비된 폴리우레탄폼 드레싱 시트에 관한 것이다.The present invention relates to a polyurethane foam dressing sheet which is used for wounds, wounds, bedsores and the like, and has various patterns and ointments of various forms on top of the polyurethane foam sheet.
일반적으로 피부에 상처가 낫을 경우 외부자극으로부터 상처를 보호하며 상처의 수분손실을 막아주도록 드레싱제로 거즈 드레싱제와 친수성 폴리우레탄폼 드레싱제가 있다. Generally, a gauze dressing agent and a hydrophilic polyurethane foam dressing agent are used as dressing agents to protect the wound from external stimuli and to prevent the loss of moisture when the wound is healed.
그러나 거즈 드레싱제는 상처분비물의 흡수 속도는 빠르나, 건소한 상태로 유지시 드레싱제가 상처 면에 밀착되어 거즈 드레싱제의 제거시 상처의 피부 일부와 함께 제거되어 신생조직의 손상 및 통증을 수반하는 문제점이 있어, 축축한 상 태를 유지하기 위하여 자주 거즈드레싱을 교체하여야하는 번거러움이 있으며, 또한 친수성 폴리우레탄폼 드레싱제는 우수한 흡수도를 갖고 있고, 적절한 습윤상태를 유지함과 동시에 상처 면에 미부착되는 장점이 있어 많이 애용되고 있다.However, the gauze dressing is fast in absorbing the wound secretion, but when it is kept in a dry state, the dressing agent adheres to the wound surface, and when the gauze dressing agent is removed, the gauze dressing is removed along with a part of the skin of the wound, thereby causing damage and pain of the new tissue. In order to maintain a moist condition, the gauze dressing needs to be replaced frequently, and the hydrophilic polyurethane foam dressing agent has an excellent absorbency, and maintains proper wet state and is not attached to the wound surface. There is a lot and is used habitually.
일반적으로 폴리우레탄폼 드레싱제는 환부 드레싱에 약제가 환부를 덮게 되어 환부 분비물 흡수가 차단, 지연, 감염(화농)이 발생 육아조직형성 및 가피형성이 지연되어 치료가 지연 흉터가 크게 남게 된다. In general, the polyurethane foam dressing agent covers the affected area with the wound dressing, so that the secretion of absorbed secretions is blocked, delayed, and infection (purine) occurs.
국내공개특허공보 공개번호 제10-2006-59385호에는 미세포아와 고점도삼출액 흡수수단이 형성된 미세다공성 폴리우레탄 필름의 상처면 접촉층과, 상기 접촉층의 상부에 접합된 지지층으로 구성된 창상피복용 드레싱제가 기재되어 있고, Korean Laid-Open Patent Publication No. 10-2006-59385 discloses a wound dressing comprising a wound surface contact layer of a microporous polyurethane film in which microblasts and high viscosity effluent absorption means are formed, and a support layer bonded on top of the contact layer. I'm listed,
동 공보 공개번호 제10-2005-91229호에는 삼출물을 흡수한 후 팽윤으로 인한 친수폼의 물성저하를 개선한 네트형 필름이 접합 되거나, 직선, 곡선, 원, 타원형 다각형 또는 이들의 조합으로 된 필름으로 구성된 폼 드레싱제가 공개되어 있으나, Publication No. 10-2005-91229 discloses a net-like film which improves the properties of hydrophilic foams due to swelling after absorbing exudates, or a film made of straight, curved, circular, elliptical polygons, or a combination thereof. Foam dressing composition consisting of the public,
상기와 같은 종래의 환부 드레싱은 약제를 환부에 바르고 그 위에 환부보호제 거즈, 드래싱폼등으로 드레싱을 하고 있으나, 이로 인하여 거즈는 환부에 달라붙어 아프고 피가 날수 있고 가피가 탈락되어 치료가 지연되고 흉터가 크게 남게 되는 문제점이 있어 왔다.Conventional wound dressings as described above are applied to the affected area with the drug applied to the wound protector gauze, dressing foam, etc. Due to this, the gauze sticks to the affected area, sore and bleeding, peeling off the skin delayed treatment and scarring There has been a problem that remains large.
상기와 같은 문제점을 해결하고자, 본 고안은 폴리우레탄폼 드레싱 시트 위에 일정량의 연고 약제를 도포하여 제조하여, 연고 약제도포무늬와 무늬 사이 공간과 무늬 크기 연고 약제량은 환부상태에 따라 선정 적용하여 사용하고, 약제는 흡수되지 않고 액상의 삼출액만을 흡수되도록 제조한 폴리우레탄폼 드레싱시트위에 환부에 알맞은 무늬와 연고약제종류, 약제의 량을 도포하여 얇은 폴리프로필렌필름(이형제)으로 덮어서 제조한 폴리우레탄폼 드레싱 시트를 제공하는 것이 본 고안이 이루고자하는 기술적 과제인 것이다.In order to solve the above problems, the present invention is produced by applying a certain amount of ointment on the polyurethane foam dressing sheet, the amount of the ointment drug coating pattern and the pattern between the pattern and the size of the ointment is selected and applied according to the affected condition Polyurethane foam prepared by covering a thin polypropylene film (releasing agent) by applying appropriate amount of pattern, ointment, and drug to the affected area on the polyurethane foam dressing sheet manufactured to absorb only liquid exudates without absorbing the drug. Providing a dressing sheet is a technical problem to be achieved by the present invention.
상기와 같은 목적을 달성하기 위하여, 본 고안은 디이소시아네이트와 폴리에테르폴리올을 반응하여 합성한 폴리우레탄프레폴리머와 발포제, 가교제, 보습제, 항균제, 계면활성제등을 첨가하여 제조하며, 미세하고 다수의 통공(pore)형태로 구성된 폴리우레탄폼 시트(1)와, 상기 폴리우레탄폼 시트(1)의 상부에 원형, 삼각형, 사각형, 육각형상에서 선택된 어느 하나의 형상으로 돌출 되도록 형성된 연고약제(2)와, 상기연고약제(2)의 상부에 적층된 투명이형지(3)로 구성되어 환부(창상)치료첨부제로서 드레싱 교치 시에 달라붙지 않고 환부의 삼출물 흡수력이 뛰어나고 분비물이 증발되는 고투습도와 친수성으로 보습기능이 우수한 폴리우레탄폼 드레싱 시트에 관한 것이다.In order to achieve the above object, the present invention is prepared by adding a polyurethane prepolymer synthesized by reacting a diisocyanate and a polyether polyol, a foaming agent, a crosslinking agent, a humectant, an antimicrobial agent, a surfactant, and the like, and a plurality of pores.
