Abstract
Description
本発明は創傷治癒を促進させ、患者の苦痛を軽減させるために用いられる創傷面接触材及びそれを用いた創傷ドレッシングに関する。 The present invention relates to a wound surface contact material used for promoting wound healing and reducing patient pain, and a wound dressing using the same.
（１）浸出液の吸液移動を水平方向に改めた提案がなされている。（特許文献１）この場合、吸液移動をより効率的に実施するために、吸液性パッド材を液体非通過性シートより大きくする必要がある。しかし、これは製造上難易度は高く、且つ、特に液体非通過性シートの周囲全域で吸液性パッド材をより大きくする場合は、さらにハイコスト要因となるので改善が望まれる。（２）被覆体又はテープ類に塗布された接着剤層と創傷面接触材が固着するため、広い面積の被覆体等が受ける歪みを狭い面積の創傷面接触材が同様に連動して受けるので創傷面には好ましくなく、したがって、この連動性を弱める必要がある。（３）通常創傷面接触材の位置は被覆体のほぼ中央である。しかし、実際は多少位置を変更したり、被覆体、創傷面接触材の大きさ、形状を変更すると都合が良い場合が多いのである。この場合、一度両者を分離し、それぞれ最適の大きさ、形状に変更後、再度、組合せて使用することが望まれている。これに関して位置変更、サイズ変更等の一部が創面接触部の存在により不可能な場合も考えられるが、分離操作そのものは可能な提案はある。（特許文献２） (1) A proposal has been made in which the liquid absorption movement of the leachate is changed in the horizontal direction. (Patent Document 1) In this case, it is necessary to make the liquid-absorbing pad material larger than the liquid non-passing sheet in order to perform the liquid-absorbing movement more efficiently. However, this is highly difficult to manufacture, and in particular, when the absorbent pad material is made larger in the entire area around the liquid non-passing sheet, it becomes a higher cost factor, so an improvement is desired. (2) Since the adhesive layer applied to the covering or tape and the wound surface contact material are fixed, the wound surface contact material of the narrow area similarly receives the distortion that the covering surface of the large area receives similarly. It is not desirable for the wound surface and therefore this interlocking needs to be weakened. (3) Usually, the position of the wound surface contact material is approximately the center of the covering. In practice, however, it is often convenient to slightly change the position or to change the size or shape of the covering or wound surface contact material. In this case, it is desired that the two are once separated, changed to the optimum size and shape, and then used again in combination. In this regard, there may be cases where part of the position change, size change, etc. is impossible due to the presence of the wound surface contact portion, but there are proposals that allow the separation operation itself. (Patent Document 2)
（１）水平移動した浸出液の垂直移動をより簡便に、より効率的に、より低コストで実施すること。（２）浸出液等の裏面しみだしを防止し、さらに二次拡散の効率化を計ること。（３）連続するスリット或いは幅が広いスリットを設けた時等において、中央部と外周縁部等が分離された状態が発生する。これを柔軟に連結すること。（４）被覆体等と創傷面接触材との連動性を弱小化すること。（５）被覆体等と創傷面接触材の分離を可能にし、それぞれの大きさ、形状等の変更を可能とすること等である。 (1) Carrying out the vertical movement of the leachate that has moved horizontally more simply, more efficiently, and at a lower cost. (2) To prevent the exudation of the exudate, etc., and to improve the efficiency of secondary diffusion. (3) When a continuous slit or a wide slit is provided, a state where the central portion and the outer peripheral edge portion are separated occurs. Connect this flexibly. (4) To weaken the interlocking between the covering body and the wound surface contact material. (5) It is possible to separate the covering and the like from the wound surface contact material, and to change the size and shape of each.
（１）吸液性パッド材と創傷面接触用液体非通過性シートを積層後、所定の形状に切断する時、又はその前後に、創傷面接触用液体非通過性シートの外周縁部の少なくとも一部に孔及び／又はスリットを設置することにより、より効率的な垂直移動を容易に実施することができる。この孔又はスリットは、創傷面接触用液体非通過性シートのみならず吸液性パッド材に及ぶこともある。又、スリットは端部のない連続した場合も含まれる。（２）尚、スリットのシート内側端部及び／又は孔外周のシート中央側を直線で結ぶ時、これらで囲まれる面積、或いは前記直線を延長し、これとシート外周端部に囲まれる面積の何れか大きい方を孔又はスリットの存在しない中央部の面積とし、又、一つの連続スリットで形成している場合は、その内側の面積をこれに充当する。これが好ましくはシート全体の面積の５０％以上、より好ましくは６０％以上、さらに好ましくは７０％以上である。（３）浸出液等の裏面しみだしを防止し、さらに二次拡散の効率化を増進させるため、創傷面接触用液体非通過性シートの反対面の少なくとも一部に液体非通過性シートを積層する。（４）連続するスリット或いは幅が広いスリットを設けた場合、中央部と外周縁部等が完全に又は部分的に分離された状態が発生するので、これを柔軟に連結するために、創傷面接触用液体非通過性シートの反対面の少なくとも一部に液体通過性シートを積層する。（５）被覆体等と創傷面接触材との連動性を弱め、さらにサイズ、形状の変更を可能にするため、双方の分離を容易に実施出来るように、創傷面接触用液体非通過性シートの反対面の少なくとも一部に離型処理加工を施した。（６）創傷面接触用液体非通過性シートの透湿度は３００ｇ／ｍ２・２４ｈ以下が好ましく、１００ｇ／ｍ２・２４ｈ以下がより好ましく、５０ｇ／ｍ２・２４ｈ以下が最も好ましい。測定方法はＪＩＳ Ｚ ０２０８の透湿度試験方法又は、ＪＩＳ Ｋ ７１２９の水蒸気透過度試験方法による。(1) After laminating the liquid-absorbing pad material and the liquid impermeable sheet for wound surface contact, when cutting into a predetermined shape, or before and after that, at least the outer peripheral edge of the liquid impermeable sheet for wound surface contact By installing holes and / or slits in a part, more efficient vertical movement can be easily performed. This hole or slit may extend to the liquid-absorbent pad material as well as the liquid impermeable sheet for contact with the wound surface. In addition, the slit includes a continuous case without an end. (2) When connecting the sheet inner end of the slit and / or the sheet central side of the outer periphery of the hole with a straight line, the area surrounded by these, or the straight line is extended, and the area surrounded by this and the outer peripheral edge of the sheet The larger one is the area of the central part where no hole or slit exists, and when it is formed by one continuous slit, the inner area is applied to this area. This is preferably 50% or more, more preferably 60% or more, and still more preferably 70% or more of the total area of the sheet. (3) A liquid non-permeable sheet is laminated on at least a part of the opposite surface of the liquid non-permeable sheet for contact with the wound surface in order to prevent exudation of the back surface of exudate and the like and further increase the efficiency of secondary diffusion. . (4) When a continuous slit or a wide slit is provided, a state in which the central portion and the outer peripheral edge portion are completely or partially separated occurs, so that the wound surface can be connected flexibly. The liquid-permeable sheet is laminated on at least a part of the opposite surface of the contact liquid-impermeable sheet. (5) In order to weaken the interlocking between the covering and the wound surface contact material and to further change the size and shape, the liquid non-permeable sheet for wound surface contact can be easily separated. A mold release treatment was applied to at least a part of the opposite surface. (6) moisture permeability is preferably from 300g / m 2 · 24h of liquid-pervious sheet wound surface contact, more preferably not more than 100g / m 2 · 24h, most preferably at most 50g / m 2 · 24h. The measuring method is based on the moisture permeability test method of JIS Z 0208 or the water vapor permeability test method of JIS K 7129.
浸出液の垂直移動効率は、吸液性パッド材を液体非通過性シートより大きくした場合に比較して、少なくとも劣ることはなく、且つ、製造方法が簡便であり、コストアップの要因とはならない。 The vertical movement efficiency of the leachate is at least not inferior to the case where the liquid-absorbing pad material is made larger than the liquid non-passing sheet, and the manufacturing method is simple and does not cause an increase in cost.
接着剤層は天然ゴム系接着剤、合成樹脂接着剤等種々の医学的に許容できる接着剤を用いて、常法により形成される。その厚さは、通常２０〜７０μｍである。剥離材は剥離紙、剥離フィルム等である。非通気性被覆体及び液体非通過性シートとしてはポリウレタン、ポリエチレン、ポリエステルフィルム等のうすく柔軟なもので医学的に許容できるものであればよく、これを単一層又は積層して使用することができる。通気性被覆体としては、紙、布、不織布、多孔質シート、上記非通気性被覆体に孔を設けたもの等医学的に許容できる、うすく、柔軟で、通気性があるものであればよく、これを単一層又は積層して使用することができる。液体通過性シートとしては、ポリエチレン、ポリエステル、紙、布、不織布等を用いて、ネット状、網状、有孔シート等に形成したもの等が使用することができる。吸液性パッド材としては紙、布、綿、不織布等吸液性があり、うすく柔軟なもので医学的に許容できるものであればよく、これを単一層又は積層して使用することができる。離型処理加工としては、シリコーン樹脂、非シリコーン樹脂等による表面加工等により、接着剤層からの剥離を容易にするものであればよい。 The adhesive layer is formed by a conventional method using various medically acceptable adhesives such as natural rubber adhesives and synthetic resin adhesives. The thickness is usually 20 to 70 μm. The release material is release paper, release film, and the like. The non-breathable covering and the liquid non-passing sheet may be thin and soft, such as polyurethane, polyethylene, polyester film, etc., as long as they are medically acceptable, and can be used as a single layer or laminated. . The breathable covering may be paper, cloth, non-woven fabric, porous sheet, or a non-breathable covering provided with holes, medically acceptable, thin, flexible, and breathable. These can be used as a single layer or laminated. As the liquid-permeable sheet, those formed into a net shape, a net shape, a perforated sheet or the like using polyethylene, polyester, paper, cloth, nonwoven fabric, or the like can be used. The liquid-absorbing pad material has a liquid-absorbing property such as paper, cloth, cotton, non-woven fabric, etc., as long as it is lightly flexible and medically acceptable, and can be used as a single layer or laminated. . Any release treatment may be used as long as it facilitates peeling from the adhesive layer by surface treatment with a silicone resin, a non-silicone resin, or the like.
