摘要:
The invention relates to a multi-layered wound dressing, particularly for the moist wound treatment, comprising a first layer as a wound contact layer, which contains an aqueous hydrogel matrix, and at least a second absorbing layer. The hydrogel matrix comprises 37 to 43% by weight of propylene glycol, a preprolymer with isophorone diisocyanate groups and a diamine on the basis of polyethylene oxide in an amount of a total of 12 to 16.5% by weight, 0 to 5% by weight of an inorganic chloride, and the remainder water, wherein the ratio of the reactive groups of isocyanate to the amine groups of the diamine should be 1.25 to 1.35.
摘要(中):
本发明涉及一种多层伤口敷料,特别是用于湿伤口治疗,包括含有水性水凝胶基质的第一层作为缠绕接触层,以及至少第二吸收层。 水凝胶基质含有37〜43重量%的丙二醇,具有异佛尔酮二异氰酸酯基团的前原体和基于聚环氧乙烷的二胺,其总量为12〜16.5重量%,0〜5重量% 无机氯化物,其余为水,其中异氰酸酯的反应性基团与二胺的胺基的比例应为1.25至1.35。
