Description

【発明の詳細な説明】 創傷包帯 この発明は創傷包帯に関する。 創傷包帯は創傷被覆部材(例えば、合成ポリマーフィルムまたは膜)および該部 材を創傷部位に固定させるための接着剤から形成される場合が多い。創傷被覆部 材は創傷に直接接触するように固定させてもよく、あるいは該部材と創傷の間に 別の包帯部材(例えば、ヒドロゲルまたはアルギン酸塩等)を介在させて固定して もよい。 創傷被覆部材は創傷自体のを被覆するだけでなく、その周辺端部において創傷 部周辺の無傷の皮膚と重なりあって付着することによって該部材を適所に固定す る。 常套の創傷被覆部材には一般に接着剤がその全表面にわたって連続層もしくは 不連続層として均一に付着されている。即ち、創傷被覆部材の全表面にわたる単 位面積あたりの接着剤の付着量は一定である。 しなしながら、皮膚の無傷領域および創傷部位と重なり合う領域にとっては接 着剤の均一付着は不適当である。例えば、創傷部周辺の無傷皮膚領域に創傷皮膚 部材を安全に固定させるのに十分な量の接着剤を均一に付着させることは該部材 の創傷部位被覆領域に対しては不適当である。逆に、該部材の創傷部位被覆領域 に対して適量の接着剤は該部材を皮膚の無傷領域へ安全に付着させるには不適当 である。 この発明の目的は上記問題点を解決もしくは軽減することである。 本発明によれば、表面上に接着剤が付着した創傷被覆部材を具有する創傷包帯 であって、該部材の周縁部を包囲する該表面の周辺領域における接着剤被覆率が 該周辺領域と境界を接する該表面の中央領域の場合よりも大きく、該周辺領域に おける接着剤被覆率が該周辺領域の面積の２０％よりも大きく、また、該中央領 域の接着剤被覆率が該中央領域の面積の最大で５０％である創傷包帯が提供され る。 従って、本発明による包帯においては、創傷被覆部材の周辺領域には中央領域 よりも多くの量の接着剤が付着される。この周辺領域は創傷部位周辺の皮膚の無 傷領域に創傷被覆部材を安全に固定させるのに用いられ、一方、接着剤の付着量 のより少ない中央領域は創傷部位を被覆するので有益である。 周辺領域においては、接着剤による被覆は連続的(１００％の被覆率)または不 連続的(２０％よりも大きくて１００％よりも小さい被覆率)であってもよい。 好ましくは、周辺領域における接着剤の被覆率は少なくとも３０％、より好ま しくは５０〜８０％とする。 好ましくは、周辺領域は創傷被覆部材の周縁端部から内側へ０．５〜２ｃｍ、 より好ましくは０．７５〜１．２５ｃｍ延びるようにする。 創傷被覆部材の中央領域においては、中央領域における接着剤による全被覆率 が５０％よりも小さくなるように(より好ましくは４０％よりも小さく、例えば ３０％よりも小さくなるように)接着剤が不連続層として付着される。従って、 例えば、第二領域の被覆率は２０％よりも小さくてもよい。 創傷被覆部材は創傷部位に直接的に接触するように固定してもよく、あるいは 該部材と創傷部位との間に別の部材を介在させて固定してもよい。 創傷被覆部材を創傷部位へ直接的に接触させる場合には、該部材の中央領域の 接着剤は、内部には接着剤が存在しない多数のセルが形成されるようなライン状 に付着させるのが好ましい。この種の好ましい態様においては、接着剤ラインは ハネカム状に配列された六角形のセルを形成する。しかしながら、セルの形態と しては別の形態、例えば四辺形等であってもよいので、必ずしも個々のセルの形 態を六角形にする必要はない。従って、中央領域の接着剤はクロスバッチ(cross -batch)状に付着させてもよい。また、セルの形態は正方形にしてもよい。 接着剤をセルを形成するようなライン状に付着させる態様の利点は、創傷被覆 部材を創傷部位と接触させたときに、セル領域内において細胞の増殖が促進され ることである。 しかしながら、創傷被覆部位の中央領域に別の包帯部材(例えば、ヒドロゲル またはアルギン酸塩)を配設する場合には、該中央領域の接着剤は該中央領域の 真ん中の点を中心とする複数の同心環(例えば、円形環または楕円環等)または部 分的な同心環の形状で付着させるのが好ましい。このような同心環は創傷部位か らの滲出液の流れを制御する。 同心状の環もしくは部分環の間の距離は創傷被覆部材の中心点から外側に向か って減少させるのが好ましい。 創傷被覆部材は膜であってもよいが、フィルムがより好ましい。 フィルムは水蒸気のみの場合に比べて水の存在下での透湿度(ＭＶＴＲ)の高い 通気性フィルムが好ましい。水の存在下でのＭＶＴＲはＡＳＴＭ Ｅ９６ＢＷに 従って測定してもよく、一方、水蒸気のみが存在するときのＭＶＴＲはＡＳＴＭ Ｅ９６Ｂに従って測定してもよい。好ましくは、水の存在下での通気能の値は 水蒸気のみの存在下での通気能の値の少なくとも２倍、より好ましくは少なくと も３倍であって、１０〜２０倍であってもよい。一般的には、この種のフィルム の材質は、水蒸気のみの存在下でのＭＶＴＲのＡＳＴＭ Ｅ９６Ｂによる測定値 が１０００〜５０００ｇｍ-2２４ｈｒ-1であって、水の存在下でのＭＶＴＲのＡ ＳＴＭ Ｅ９６ＢＷによる測定値が３０００〜３００００ｇｍ-2２４ｈｒ-1のも のである。この種のフィルムの一般的な厚さは２０〜７０ミクロン、より好まし くは３０〜５０ミクロン、例えば、約４０ミクロンである。 このようなフィルムの材質は、例えば、ポリウレタンであってもよい。適当な フィルムとしてはイノベイティブ・テクノロジーズ社の市販品「Ｂ５３−２」、「 Ｃ５４−２」および「Ｄ５６−２」が例示される。 接着剤としては感圧接着剤が好ましい。もちろんこの種の接着剤は医療上許容 されるものでなければならない。 適当な接着剤としてはイノベイティブ・テクノロジーズ社から市販されている 感圧接着剤「ＩＴ ＰＳＡ ＨＴ」および「ＰＳＡ ＬＴ」が例示される。 以下、本発明の実施例を添付図に基づいてさらに説明する。 図１は本発明による創傷包帯の一態様を示す接着剤層側からの平面図である。 図２は本発明による創傷包帯の別態様を示す接着剤層側からの平面図である。 図１において、包帯(１)は透湿性フィルム(２)を有しており、該フィルムの一 方の表面(即ち、図１に示す面)の２つの異なった領域内に接着剤が付着される。 第一の領域はフィルム(２)の周縁部を包囲する周辺領域(３)であり、該領域に は２０％よりも大きな被覆率、例えば、５０％以上の被覆率で接着剤が付着され る。 別の領域は該周辺領域と境を接する領域であって、創傷と直接的に接触する領 域である。この中央領域においては、接着剤はハネカム状に配設された六角形の セルを形成するライン(４)として付着される。 図１に示す態様の包帯は中央領域を創傷部位に直接的に接触させて治療をおこ なう場合に適している。これは、中央領域におけるハネカム状のセルが細胞の増 殖を促進するからである。 図２において、包帯(２０)は包帯の周縁部を包囲する周辺領域(２１)に付着さ れた接着剤を有する。この周辺領域における接着剤の被服率は２０％よりも大き く、例えば５０％である。 包囲の中央領域にはその真ん中の点を中心とする円心状の円(２２)および部分 円(２３)の状態で接着剤が付着される。隣接する円(２２)または部分円(２３)の 間の領域には接着剤は付着されないので、中央領域の接着剤の全被覆率は２０％ よりも小さくなる。 円(２２)および部分円(２３)の間隔は包帯の中心から半径方向に外側に向かっ て小さくなる。 図２に示す包帯は被覆部材と創傷の間に別の部材(例えば、ヒドロゲルまたは アルギン酸塩等)を介在させて固定するのに特に適している。 同心円は滲出液の流出を防止するのに有効である。DETAILED DESCRIPTION OF THE INVENTION Wound Dressing The present invention relates to wound dressings. Wound dressings are often formed from a wound dressing (eg, a synthetic polymer film or membrane) and an adhesive to secure the member to the wound site. The wound dressing may be secured in direct contact with the wound, or may be secured with another dressing member (eg, hydrogel or alginate) between the member and the wound. The wound dressing member not only covers the wound itself, but also secures the member in place by overlapping and adhering at its peripheral edge to the intact skin around the wound. Conventional wound dressings generally have the adhesive uniformly applied as a continuous or discontinuous layer over the entire surface. That is, the adhesive amount per unit area over the entire surface of the wound covering member is constant. However, for an intact area of the skin and an area that overlaps the wound site, a uniform application of the adhesive is inappropriate. For example, evenly applying a sufficient amount of adhesive to safely secure a wound skin member to an intact skin region around a wound is inappropriate for the wound site covering area of the member. Conversely, an adequate amount of adhesive to the wound site coverage area of the member is unsuitable for safely attaching the member to an intact area of the skin. An object of the present invention is to solve or reduce the above problems. According to the present invention, there is provided a wound dressing having a wound covering member having an adhesive adhered on a surface, wherein an adhesive coverage in a peripheral region of the surface surrounding a peripheral portion of the member has a boundary with the peripheral region. , The adhesive coverage in the peripheral region is greater than 20% of the area of the peripheral region, and the adhesive coverage in the central region is greater than the area of the central region. A wound dressing is provided that is up to 50% of the wound dressing. Thus, in a dressing according to the invention, a greater amount of adhesive is applied to the peripheral area of the wound dressing than to the central area. This peripheral area is used to safely secure the wound dressing to the intact area of the skin around the wound site, while the central area with less adhesive coverage is beneficial because it covers the wound area. In the peripheral area, the coating with the adhesive may be continuous (100% coverage) or discontinuous (greater than 20% and less than 100%). Preferably, the coverage of the adhesive in the peripheral region is at least 30%, more preferably 50-80%. Preferably, the peripheral area extends inward from the peripheral edge of the wound dressing by 0.5-2 cm, more preferably 0.75-1.25 cm. In the central region of the wound dressing, the adhesive is applied such that the total coverage of the adhesive in the central region is less than 50% (more preferably less than 40%, for example less than 30%). Applied as a discontinuous layer. Thus, for example, the coverage of the second region may be less than 20%. The wound covering member may be fixed so as to be in direct contact with the wound site, or may be fixed with another member interposed between the member and the wound site. When the wound covering member is brought into direct contact with the wound site, the adhesive in the central region of the member should be applied in a line so as to form a large number of cells with no adhesive inside. preferable. In a preferred embodiment of this type, the adhesive lines form hexagonal cells arranged in a honeycomb pattern. However, since the cell may be in another form, for example, a quadrilateral, the shape of each cell does not necessarily need to be hexagonal. Thus, the adhesive in the central region may be applied in a cross-batch manner. Further, the form of the cell may be square. An advantage of the embodiment in which the adhesive is applied in a line to form cells is that cell growth is promoted in the cell region when the wound dressing is brought into contact with the wound site. However, if another dressing member (e.g., hydrogel or alginate) is placed in the central region of the wound covering site, the adhesive in the central region will have a plurality of concentric centers about a center point in the central region. It is preferably attached in the form of a ring (eg, a circular or elliptical ring) or a partially concentric ring. Such concentric rings control the flow of exudate from the wound site. Preferably, the distance between the concentric rings or partial rings decreases outward from the center point of the wound dressing. The wound dressing may be a membrane, but more preferably a film. The film is preferably a breathable film having a higher moisture permeability (MVTR) in the presence of water than that of a case using only water vapor. MVTR in the presence of water may be measured according to ASTM E96BW, while MVTR when only water vapor is present may be measured according to ASTM E96B. Preferably, the value of the permeability in the presence of water is at least twice, more preferably at least 3 times, and even 10 to 20 times the value of the permeability in the presence of water vapor alone. Generally, the material of this type of film has a MVTR measured by ASTM E96B in the presence of water vapor alone of 1000-5000 gm -2 24 hr -1 and an ASTM of the MVTR in the presence of water. The value measured by E96BW is 3000 to 30000 gm -2 24 hr -1 . Typical thicknesses of such films are 20-70 microns, more preferably 30-50 microns, for example about 40 microns. The material of such a film may be, for example, polyurethane. Examples of suitable films include commercially available products "B53-2", "C54-2" and "D56-2" from Innovative Technologies. As the adhesive, a pressure-sensitive adhesive is preferable. Of course, this type of adhesive must be medically acceptable. Suitable adhesives include the pressure sensitive adhesives "IT PSA HT" and "PSA LT" available from Innovative Technologies. Hereinafter, embodiments of the present invention will be further described with reference to the accompanying drawings. FIG. 1 is a plan view of one embodiment of a wound dressing according to the present invention, as viewed from an adhesive layer side. FIG. 2 is a plan view from the side of the adhesive layer showing another embodiment of the wound dressing according to the present invention. In FIG. 1, the bandage (1) has a moisture permeable film (2), on which adhesive is applied in two different areas on one surface of the film (ie the surface shown in FIG. 1). . The first area is a peripheral area (3) surrounding the periphery of the film (2), to which an adhesive is applied with a coverage of more than 20%, for example, 50% or more. . Another area is an area that borders the peripheral area and is in direct contact with the wound. In this central area, the adhesive is applied as lines (4) forming hexagonal cells arranged in a honeycomb. The dressing of the embodiment shown in FIG. 1 is suitable for the case where the central region is brought into direct contact with the wound site for treatment. This is because the honeycomb-shaped cells in the central region promote cell growth. In FIG. 2, the bandage (20) has an adhesive applied to a peripheral area (21) surrounding the periphery of the bandage. The coverage of the adhesive in this peripheral area is greater than 20%, for example 50%. Adhesive is applied to the center area of the enclosure in the form of a concentric circle (22) and a partial circle (23) centered on the center point. No adhesive is applied to the area between adjacent circles (22) or partial circles (23), so that the total coverage of the adhesive in the central area is less than 20%. The distance between the circle (22) and the partial circle (23) decreases radially outward from the center of the bandage. The dressing shown in FIG. 2 is particularly suitable for securing another member (eg, hydrogel or alginate) between the covering member and the wound. Concentric circles are effective in preventing exudate outflow.
