测定横跨食道粘膜的电位差及食道压力是研究消化道粘膜功能的一种重要方法。它有助于食道粘膜疾病的诊断;同时,通过检测食道内压,对研究正常食道的生理功能以及诊断食管炎、食道癌,上、下部食道功能、食道闭锁术后功能,胃食道逆流等疾病具有重要意义。河南省医科所薛乐勋教授研制出第一台食道压力、电位记录仪样机之后,此项工作进入实用阶段,但因种种原因,该机未能投产,不能满足各医疗单位的需要。我们在薛教授的指
Determination of the potential difference across the esophageal mucosa and esophageal pressure is to study the mucosal function of the digestive tract is an important method. It is helpful for the diagnosis of esophageal mucosal diseases. At the same time, through the detection of esophageal pressure, the study of the physiological function of the normal esophagus and the diagnosis of esophagitis, esophageal cancer, upper and lower esophageal function, esophageal atresia postoperative function, gastroesophageal reflux disease It is of great significance. After Xue Xuexun, professor of Henan Province Medical Institute developed the first prototype of esophageal pressure and potential recorder, this work has entered a practical stage. However, due to various reasons, the machine failed to be put into production and could not meet the needs of various medical units. We are referring to Professor Xue
