摘　　要：本文阐述人工机械心脏瓣膜体外性能检测的原理和方法,对我国自行研制、生产的四种人工机械心脏瓣膜进行检测和对照,并和美国Bj(o|¨)rk—shiley瓣膜的相应测试曲线进行比较。大量的数据、曲线表明我国目前生产的四种瓣膜的体外模拟通流性能都已达到了美国FDA的规定要求,标志着我国生产的人工机械心脏瓣膜质量已跃进了国际水平,为我国人工机械心脏瓣膜体外性能检测的标准化及检测标准的制定,提供了有价值的数据。文中还对我国生产的四种瓣膜的体外血流动力学特性作出评价。This paper discusses the theory and method of the in vitro he-modynamic characteristic test.Four mechanical Valves,which havebeen studied,designed,and made by our country,are studied in theaortic position under pulsatile flow conditions.The comparisons ofthe characterrstics are made between the four valves and a Bj(o|¨)rk-Shiley mechanical valves(made in U.S.A)in the same type andsame size.Lots of data,gained by our test,and the comparisonshave showed that the in vitro hemodynamic characteristics of ourcountry four mechanical vales have come up to the FDA's standards.It marks that our country valve production quality has reached the inter-national level and provided valuable data for in vitro valve funtiontest standardization and making these standards of our country's.The paper also evaluates the vitro hemodynamic characteristics ofthe four valves.
