人的微血管管径为7～12μm,在输液中经各种途径污染的直径相近的非代谢性微粒进入微血管后便会停留下来,这种堵塞会使细胞受损坏死,引起血栓、动脉炎、静脉炎、肉芽肿等。我国现用的静脉输液与国外一样也用了预过滤,并生产了纤维素滤膜输液终端过滤器。为了改进过滤器性能,我们将聚碳酸酯或涤纶核孔滤膜用于终端过滤器,通过几项主要指标(截留微 Human microvascular diameter of 7 ~ 12μm in the infusion of a variety of ways by the pollution of similar diameter non-metabolic particles into the microvascular will stay, this blockage will make the cell damage necrosis, causing thrombosis, arteritis, Phlebitis, granuloma and so on. Our current intravenous infusion is also used with foreign pre-filter, and the production of cellulose filter infusion terminal filter. In order to improve the performance of the filter, we use polycarbonate or polyester nuclear membrane filter for the terminal filter, through several key indicators (Trapped micro
