摘要
论述了一种新的上消化道动态多点ｐＨ监测传感器导管，导管上集成有多个锑电极和一个ＡｇＡｇｃｌ参比电极管。胃液抽取法和动态监测法对照的动物实验证实了技术的可靠性。将此传感器导管用于临床研究。
A new transducer catheter used for dynamic multi location pH monitoring in upper digestive tract has been developed.On the catheter several antimony electrodes and an Ag Agcl electrode are integreted.An animal experiment compared the results of gastric aspiration and dynamic recording and demonstrated the reliability of this transducer.Clinical application has shown that this technology contributes greatly to the research on digestive physiology and to the diagnosis of functional diseases such as non cardiac chest pain.
