摘要： The present invention relates to a polyurethane foam dressing material with improved moisturizing rate. More precisely, the present invention relates to a hydrophilic dressing material in which a wound contact layer (10) having a sponge structure composed of multiple open cells (12) and pores (15) passing through the cells (12) is laminated with a protective film (20). The lamination is characteristically performed at 150˜250° C. under a pressure of preferably 0.25˜1 kgf/cm2, the moisturizing rate of the wound contact layer (10) is 300˜1200% and the pore area (membrane opening) takes 10˜35% of the total cell area.The polyurethane foam dressing material of the present invention prevents the invasion of foreign materials, releases absorbed exudation after changing it into water vapor or arresting the absorbed exudation inside the foam to maintain constant moisturizing, has excellent exudation absorption capacity, has a wound healing effect resulting from not adhering to a wound, is easy to change, and enhances the wound healing effect by maintaining optimum moisturizing conditions resulting from the improved moisturizing rate.
摘要翻译： 本发明涉及具有改善的保湿速率的聚氨酯泡沫敷料材料。 更准确地说，本发明涉及一种亲水敷料，其中具有由多个开孔（12）构成的海绵结构的伤口接触层（10）和穿过电池（12）的孔（15） 电影（20）。 层压特性在150〜250℃，优选0.25〜1kgf / cm 2的压力下进行，缠绕接触层（10）的保湿率为300〜1200％， 孔面积（膜开口）占细胞总面积的10〜35％。 本发明的聚氨酯泡沫敷料材料防止异物侵入，在将其变成水蒸气之后释放吸收的渗出物，或阻止泡沫内吸收的渗出物以保持恒定的保湿，具有优异的渗出吸收能力，具有创伤愈合效果 从不附着伤口容易变化，通过保持由保湿效果提高而得到的最佳保湿条件，提高伤口愈合效果。
