title: [Advanced development of blood-gas exchanger].
abstract: 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 connectors link up mutually in the extracorporeal blood circulation of dialysis, may help clinical operations become safe, convenient and easily-controlled, and may simplify the technique of EGMO.
