[Abstract] Objective To study the bacteria resistance of the medical polysaccharide, China accharide hemostatic healing sponge. Methods The test method for primary wound dressing YY/T 0471.5-2004 was referenced, a medical spunlaced nonwoven was as control, the effect of bacteria resistance of the secondary dressing was inspected. Results Medical polysaccharide hemostatic healing sponge's secondary dressing had bacterial isolation performance against staphylococcus aureus aerosol, and bacteria resistance performance against serratia marcescens or vibrio alginolyticus under low moisture conditions, semi wet conditions and wet conditions. Conclusion Medical polysaccharide hemostatic healing sponge's secondary dressing has the effect of bacteria resistance.

在外伤止血尤其是战伤止血材料的研究中,以多聚糖类为主要成分的止血材料占据了重要地位。医用多糖止血愈合海绵是由江苏昌吉永生物科技有限公司研发的,是具有止血及愈创作用的新型创面敷料,其功能性部分为疏松多孔的海绵状结构,阻隔细菌性能较差,而远隔创面,起衬托、固定等作用的辅助敷料结构致密,为一层疏水膜,具有阻菌、阻水、透湿等性能,在实际使用中辅助敷料的外径超过功能性部分,起到隔离外界物质接触创面的作用。本研究以此辅助敷料作为实验对象,研究其阻隔细菌的性能。现报道如下:

1 材料与方法

1.1 材料

1.1.1 菌种 金黄色葡萄球菌标准菌株(ATCC25923)、粘质沙雷菌临床分离株、溶藻弧菌临床分离株均由解放军海军总医院检验科提供。分别在培养基上增菌后可见典型菌落,并且能够正常传代。

1.1.2 敷料 实验组:医用多糖止血愈合海绵的辅助敷料(江苏昌吉永生物科技有限公司,专利号:2012204 33377.2),厚约0.38 mm的单层疏水膜;……
