Description
본 발명은 환부에 불투명 창상피복재가 첨부된 경우에도 환부의 레이저 치료(조사)가 가능한 창상피복재 및 이를 제조하기 위한 의료용 삽입기구에 관한 것으로, 불투명 창상피복재의 일 부분에 광학적 투명성이 부여됨으로써 상기 부분을 통해 레이저 조사가 가능한 창상피복재 및 이의 제조 기구에 관한 것이다.The present invention relates to a wound garment that can be laser-treated (irradiated) of the affected part even when an opaque wound dressing is attached to the affected part, and a medical insertion device for manufacturing the same, wherein the optical transparency is provided to a part of the opaque wound coating part. It relates to a wound coating material and a manufacturing apparatus thereof capable of laser irradiation through.
화상, 외상, 창상, 욕창 등과 같은 피부 상처의 종래 치료 방법으로는 창상에 소독약을 도포하고, 거즈, 솜과 같은 흡수성 재료를 이용하여 창상 부위를 덮어 창상에서 발생되는 삼출액을 흡수하여 상처 부위를 건조시키는 방법으로 치료하였으나, 근래 연구 결과로는 창상 부위에 적당한 습윤환경이 유지되는 것이 오히려 창상 치료에 효과적임이 밝혀지면서 다양한 형태, 재료의 창상피복재들이 개발되어 시판되고 있다.Conventional treatment methods for skin wounds such as burns, traumas, wounds, bedsores, etc. apply disinfectants to the wounds and cover the wounds with absorbent materials such as gauze and cotton to absorb the exudates from the wounds to dry the wounds. However, recent studies have shown that it is effective to treat wounds rather than maintaining a suitable wet environment at the wound site. Thus, wound coating materials of various shapes and materials have been developed and marketed.
일반적으로 창상피복재에는 습윤 유지, 흡수성, 방수성, 통기성, 감염방지, 점착성, 탄성, 기계적 강도 등 다양한 물성이 요구된다.In general, wound coatings require a variety of physical properties such as moisture retention, absorbency, waterproofness, breathability, infection prevention, adhesiveness, elasticity, and mechanical strength.
이러한 창상피복재의 형태로는 필름형, 폼형, 부직포형, 이들의 복합형 등이 있으며, 창상피복재의 재료로는 폴리우레탄 필름, 폴리우레탄 폼, 하이드로콜로이드, 하이드로겔, 소듐알지네이트 겔, 콜라겐, 실리콘, 생체적합성 고분자 등이 이용되고 있다. 한편, 깊은 화상, 외상, 당뇨병성 족부궤양과 같은 피부 결손의 치료를 위하여 인공진피 이식을 통한 피부 재건이 요구되기도 한다. 창상피복재의 한 종류인 이러한 인공진피 제품은 외부층은 실리콘으로 구성하여 체액 증발을 막고, 내부층은 콜라겐으로 구성하여 새로운 혈관과 결합조직의 재생을 유도하는 것으로서, IntegraTM(미국, Lifesciences사), TerudermisTM(일본, Olympus Terumo Biomaterial사), PelnacTM(일본, Gunze사), MatridermTM(독일, Skin Health, Billerbeck사) 등의 있으며, 동종 진피제품에는 인체피부 조직으로부터 면역반응을 일으키는 표피 및 진피세포를 제거한 후 글라이세롤(glycerol-preserved)처리나, 동결시킨 진피조직으로 AllodermTM(미국, Life Cell사) 및 SuredermTM(한국, 한스바이오매드) 등이 있다.Examples of such wound coating materials include film type, foam type, nonwoven fabric type, and composite types thereof. The materials of the wound coating material include polyurethane film, polyurethane foam, hydrocolloid, hydrogel, sodium alginate gel, collagen, and silicone. And biocompatible polymers are used. Meanwhile, skin reconstruction through artificial dermal transplantation may be required for the treatment of skin defects such as deep burns, trauma and diabetic foot ulcers. This artificial dermal product, a kind of wound dressing, is composed of silicone outer layer to prevent evaporation of body fluid and inner layer is composed of collagen to induce the regeneration of new blood vessels and connective tissue. Integra TM (Lifesciences, USA) , Terudermis TM (Olympus Terumo Biomaterial, Japan), Pelnac TM (Gunze, Japan), Matriderm TM (Germany, Skin Health, Billerbeck, Inc.), and the like. After removing the dermal cells, glycerol-preserved treatment or frozen dermal tissues include Alloderm TM (Life Cell, USA) and Surederm TM (Hans Biomad, Korea).
한편, 창상피복재와 별도로, 창상 치료에 있어서 최근 광선요법이 주목받고 있다. 광선요법이란 다양한 광원을 이용하여 피부 내의 생화학적 반응을 촉진하는 방법으로, 한의학 분야에서도 광범위하게 레이저 치료가 이용되는 데, 치료 형태에 따라 레이저 침(laser acupuncture), 경근레이저, 경피레이저, 또는 오관레이저 등으로 나뉘어 불리기도 한다.On the other hand, apart from wound dressings, phototherapy has recently attracted attention in the treatment of wounds. Phototherapy is a method of promoting biochemical reactions in the skin using various light sources. Laser therapy is also widely used in the field of oriental medicine. Depending on the type of treatment, laser acupuncture, carotid laser, transdermal laser, or ureter It is also called a laser.
이러한 레이저 침은 손상된 피부조직의 콜라겐 합성을 증가시키고 염증을 감소시키는 등 피부 결손의 재건과정에 중요한 요소들의 기능을 회복하는데 도움을 주는 것으로 알려져 있다. 레이저 침을 비롯한 다양한 레이저 치료요법에서는 다양한 파장에 따라 세포와 피부조직에 투과 정도가 다른 것으로 알려져 있다. 실제 인체 피부조직을 대상으로 한 연구에서 400 nm 파장은 1 mm 이하의 투과력을 나타내는 반면, 700 ~ 900 nm 의 경우는 진피층까지 투과하는 것으로 알려져 있다. 임상 연구들에 따르면, 당뇨병성 궤양에 630 ~ 980 nm 의 다양한 레이저 파장이 사용되고 있다.Such laser needles are known to help restore the function of important factors in the reconstruction of skin defects, such as increasing collagen synthesis and reducing inflammation of damaged skin tissues. Various laser therapies including laser needles are known to vary the degree of transmission to cells and skin tissues according to various wavelengths. In actual studies of human skin tissue, 400 nm wavelength is known to transmit less than 1 mm, while 700 to 900 nm is known to transmit to the dermis. Clinical studies have shown that various laser wavelengths between 630 and 980 nm are used for diabetic ulcers.
이러한 레이저 치료에 있어서, 그 치료 효과는 레이저의 파장 뿐 아니라 중간 매체의 광학적 투명성에 큰 영향을 받는 것으로 알려져 있다. 즉, 레이저가 투과되는 중간 매체의 광투과도가 매우 중요한 요소인 데, 불투명한 창상피복재와 병용하는 경우 레이저 투과도가 낮아 충분한 레이저 치료 효과를 발휘할 수 없는 문제가 발생한다.In such laser treatment, the therapeutic effect is known to be greatly influenced by the wavelength of the laser as well as the optical transparency of the intermediate medium. That is, the light transmittance of the intermediate medium through which the laser is transmitted is a very important factor, but when used in combination with an opaque wound coating material, there is a problem in that the laser transmittance is low and sufficient laser treatment effect cannot be exhibited.
통상적으로 창상피복재는 환부의 관찰을 위해 투명한 재질로 제조되기도 하나, 환부에 대한 시각적 혐오감, 불투명한 재료의 사용 또는 여러 재료들의 다층 구조로 인해 피부색이나 백색 등과 같은 불투명으로 제조되기도 한다. 이렇게 창상피복재가 불투명한 경우, 또는 두께가 있는 경우에는 레이저 치료의 병용 치료가 불가능하거나 어려운 문제점이 있다.Typically, wound dressings are made of a transparent material for observation of the affected area, but may also be made opaque, such as skin color or white, due to the visual aversion to the affected area, the use of opaque materials, or the multi-layered structure of various materials. When the wound coating is opaque or thick, the combination treatment of laser treatment is impossible or difficult.
본 발명은 상술한 문제점을 해결하기 위한 것으로, 시판되는 불투명한 창상피복재를 이용하여 시술자가 원하는 창상피복재 위치에 투명성을 부여함으로써, 투명한 부분을 통해 레이저 치료(조사)가 가능하도록 하여, 치료의 효과를 높일 수 있는 창상피복재와, 이러한 창상피복재를 제조하는 데 이용되는 투명 부재 삽입을 위한 의료용 삽입기구를 제공하는 데 그 목적이 있다.The present invention is to solve the above-mentioned problems, by using a commercially available opaque wound dressing to give transparency to the position of the wound dressing desired by the operator, to enable laser treatment (irradiation) through the transparent portion, the effect of the treatment An object of the present invention is to provide a wound coating material capable of raising the medical coating device for inserting a transparent member used to manufacture such a wound coating material.
