The present invention provides wound healing or wound care polymer compositions that can be formulated to release a wound healing agent at a controlled rate by adjusting the various components of the composition. The compositiona can be used in an external wound dressing, as a polymer implant for delivery of the wound healing agent to an internal body site, or as a coating on the surface of an implantable surgical device to deliver wound healing agents that are dispersed in a biodegradable polymer or hydrogel, or both. Methods of using the invention bioactive polymer compositions to deliver wound healing agents that promote natural healing of wounds, especially chronic wounds, are also provided.
本发明提供了伤口愈合或伤口护理聚合物组合物,可通过调整组合物的各种成分,配制成以可控速率释放伤口愈合剂的组合物。该组合物a 可用于外部伤口敷料,也可用作聚合物植入物,将伤口愈合剂输送到身体内部部位,还可用作可植入手术器械表面的涂层,以输送分散在
生物可降解聚合物或
水凝胶中的伤口愈合剂,或两者兼而有之。本发明还提供了使用本发明
生物活性聚合物组合物输送伤口愈合剂的方法,可促进伤口,尤其是慢性伤口的自然愈合。
