促创伤修复生物海绵材料及其制备方法
摘要：
本发明涉及促进伤口，特别是皮肤组织大面积损伤修复的海绵材料及其制备方法。促创伤修复生物海绵材料包括主要由用壳聚糖、糖胺多糖等改性的胶原蛋白组成的生物活性海绵材料，其特征在于：所述的每克生物活性海绵材料中含有不少于10ng的生长因子。本促创伤修复生物海绵材料可以使药物从载体材料中以长时间持续投用的有效量释放到伤口部位，充分发挥生长因子的诱导作用，可明显缩短伤口愈合的时间，并可使愈合后的新生组织与周围组织的外观接近，可避免留下明显的疤痕，因此可以应用于各类手术中止血，急性外伤止血，各类手术后残腔填塞，烧烫伤，美容整形术以及溃疡、瘘道、褥疮、妇科宫颈糜烂等肉芽创面。
摘要（英）：

The present invention relates to bioactive sponge material for repairing wound, especially large area tissue damage skin, and its preparation process. The wound repairing bioactive sponge material consists of mainly chitosan, glycosaminoglycan and other modified collagen, and features that each gram of the bioactive sponge material contains at least 10 ng of growth factor. The wound repairing bioactive sponge material can release medicine in effective amount from the carrier material to the wound and make best use of the inducing effect of the growth factor to shorten the wound healing time and avoid obvious scar. It may be applied in various surgical operation and for various kinds of wound.
