Abstract
【解決手段】本発明は、粘着性シリコーンでコーティングされた側帯部を備える吸収性被覆材に関し、該被覆材は、特に、潰瘍や痂皮等の慢性創傷、又は、熱傷等の急性創傷の治療における使用に適している。上記吸収性被覆材は、通気性及び不浸透性を有する基材(4)と、吸収性不織布(6)とを備える。上記基材は、連続フィルム(4a)と透孔を有する補強材とを組み合わせて形成され、上記補強材はその孔を塞ぐことなく粘着性シリコーンゲル(4b)でコーティングされている。非吸収性ウェブ(5)が、上記吸収性不織布(6)には全く固定されずに、上記吸収性不織布(6)を包みこむように補助不織布(7)に固定される。次いで、包み込まれた吸収性不織布は、上記基材(4)のシリコーンでコーティングされた表面部分で上記基材(4)に組み合わせられる。
【選択図】図1
Description
・上記基材は、連続フィルムと透孔を有する補強材とを組み合わせて形成され、上記補強材の少なくとも1つの面は上記補強材の孔を塞ぐことなく粘着性シリコーンゲルでコーティングされており、上記補強材は上記連続フィルムの表面全体を覆っており、
・上記被覆材は、非吸収性ウェブと補助不織布を更に備え、上記非吸収性ウェブと上記補助不織布は、好ましくは上記吸収性不織布には全く固定されずに、上記吸収性不織布を包み込みながらそれぞれの周縁部に沿って互いに固定されており、
・上記非吸収性ウェブは、上記補強材にコーティングされた上記粘着性シリコーンゲルに接着している、被覆材である。
・補助不織布7:滲出液と接触しても崩壊せず、吸収性不織布6に含まれる繊維と超吸収性ポリマー粒子による創傷の汚染を防ぐ。
・不連続な界面層1:親水コロイド粒子を含有するエラストマー系組成物からなる。
・剥離式の保護材3:界面層1を保護する。
