摘　　要：为了让体外生命支持技术能够广泛的应用临床,辅助重症呼吸衰竭的救治,我们研制了一种体积小、结构简单的血气交换器。该装置的气、血交换模式是交叉流式,血液在中空纤维外流动,氧气在中空纤维内逆血流方向通过。血液流入、流出接口是内螺旋设计,接口口径与血液透析管路口径一致,解决了与一次性使用血液透析体外循环血路中的螺旋接头相互连接配套问题,临床使用安全、方便、易于管理,简化体外膜氧合技术。In order to simplify the technique of extracorporeal membrane oxygenation （ECMO） and apply extracorporeal life support （ECLS） broadly for assisting the treatment of severe respiratory failure patients, we have developed a blood-gas exchanger （BGE） with the characteristics of small volume and simple structure. The exchange between blood and gas of BGE adopts cross-flowing model; blood flows along the outer hollow fiber and gas flows in the inner hollow fiber with the reverse direction of blood flowing. The interface of blood flow in and out was designed as the internal spiral, and the caliber of BGE is matched with the blood interface of dialysis. Thus it may successfully make single-use spiral con- nectors link up mutually in the extracorporeal blcod circulation of dialysis, may help clinical operations become safe, convenient and easily-controlled, and may simplify the technique of ECMO.
