几种国产聚氨酯海绵的生物安全性评价

good histocompatibility and blood—compatibility,which have achieved the
request of the primary detection of biosecurity and the experiment before
clinical application.111is study provides a important reference for clinical application in future.

to L.929 collagenoblast of mice and the cytotoxicity grades of leaching liquor
of cell culture fluid are confined to 0 tO l grade,which fit the ASTM
standards. Conclusion:The four kinds of polyurethane sponges made in China have
closure has merits of saving human and health resources,increasing regional blood flows of raw surface and eliminating oedema and infest quickly.etc,it will have major potentiality in treating skin and soft tissue injury under the condition ofanti.invasive Wars,natural disasters and rescues in the future.
封闭负压引流技术在欧美已广泛开展,目前应用的海绵敷料主要为聚 乙烯醇(PVA)和聚氨酯(PUE)两类,己通过FDA认证。国内目前上述两 种海绵材料均有生产,以后者居多,临床上虽有少数单位将其用于I临床, 但缺乏安全性实验检测数据。本实验作为与V.Ac作用机理研究和负压仪 研制相关的配套研究项目拟对四种国产聚氨酯海绵进行生物安全性评价, 以推动这一技术在我国的推广应用。本实验分为两个部分:
complete and systematic datum of biosecurity evaluation.This experiment aims to make further study on biosecurity of Polyurethane Sponges Made in China.We Studied as follows in two parts:
three passages of vein,belly cavity and mouth),chronic toxicity test,hemolysis test,micronucleus test,pyrogenic test,endermic injection test,intramuscular injection test,skin sensitization test and skin irritation test.Results:the four kinds of polyurethane sponges have no acute and chronic toxicity,hemolysis,

中文摘要
平、战时期皮肤软组织伤的发生率均较高,现代武器和工具的发展也 使得伤情复杂化。封闭负压引流技术(vacl2ur'f1.assisted closure,V.A.C.) 因具有节约人力和卫生资源,迅速消除水肿和感染并加速创面愈合的特 点,使其在未来反侵略战争,自然灾害和抢险救灾条件下治疗皮肤软组织 伤具有较大潜力。
