A wet wound dressing which is formed by hydrophilic polyurethane foams is provided. The hydrophilic polyurethane foams are formed by the hydrophilic polyurethane and foaming composition. The hydrophilic polyurethane is made of a first polyether polyol reacting with polyisocyanate, and then turns to a star-shaped hydrophilic polyurethane by reacting with a second polyether polyol. The first polyether polyol contains at least three of terminal hydroxyl groups. The hydrophilic polyurethane foams are non-continuous closed holes. Since the wet wound dressing has superior permeability, absorbability and preventing adhesions, it could improve wound healing by prolonging the interval of dressing change.本發明揭露一種溼式創傷敷料,其由親水性聚氨酯發泡體形成,親水性聚氨酯發泡體係由親水性聚氨酯與發泡組分發泡而形成。其中,親水性聚氨酯係由第一聚醚多元醇與多異氰酸酯反應,接著與第二聚醚多元醇反應而形成星狀聚氨酯,其中第一聚醚多元醇係含有至少三個末端羥基。其中,親水性聚氨酯發泡體的孔洞係為非連續式的封閉孔洞。藉由本發明的創傷敷料具有良好的透氣性、吸水性,並且防止傷口沾黏的特性,能延長更換敷料的時間,以促進傷口的癒合。100‧‧‧親水性聚氨酯發泡體110‧‧‧接觸層111‧‧‧第一孔洞120‧‧‧吸收層121‧‧‧第二孔洞200‧‧‧透氣層S‧‧‧皮膚W‧‧‧傷口
