    • A biocompatible wound dressing comprised of a pad for insertion substantially into a wound site and a wound drape for sealing enclosure of the foam pad at the wound site. The pad, comprised of a foam or other like material having relatively few open cells in contact with the areas upon which cell growth is to be encouraged so as to avoid unwanted adhesions, but having sufficiently numerous open cells so that drainage and negative pressure therapy may continue unimpaired, is placed in fluid communication with a vacuum source for promotion of fluid drainage, as known in the art. The pad is further comprised of an ultra-low density fused-fibrous ceramic, or a bioabsorbable branched polymer, or cell growth enhancing matrix or scaffolding.
    • 一种生物相容性伤口敷料,其包括用于基本上插入伤口部位的垫,以及用于密封伤口部位上泡沫垫的外壳的伤口罩。 衬垫由泡沫或其他类似材料组成,具有相对较少的开放细胞与鼓泡细胞生长的区域相接触,以避免不必要的粘连,但是具有足够多的开放细胞,使得排泄和负压治疗可以 继续未受损,与本领域已知的用于促进流体排出的真空源流体连通。 该垫还包括超低密度熔融纤维陶瓷或生物可吸收支化聚合物,或细胞生长增强基质或脚手架。
