Background Gastroesophageal reflux disease (gastroesophageal reflux disease, GERD) is a disease in which discomfort symptoms and/or complications are caused by reflux of gastric contents into the esophagus, is a common disease in western countries, has an adult incidence rate of 35-40%, and has an ascending trend year by year. The prevalence rate of the disease in China is about 5 percent. With the problems of life style change, population aging and the like caused by economic development of China, the morbidity is gradually increased. Esophageal 24-hour impedance-pH monitoring is a gold standard for detecting gastroesophageal reflux disease. The monitoring requires that a small catheter is inserted from the nasal cavity into the abdominal position, and the catheter may be folded by misoperation during the intubation process, and a certain probability is also caused to be folded by sneeze or tearing during the monitoring process. The catheter is folded, so that the data of a far-end channel is invalid, even the whole data is invalid, and the accuracy of a monitoring result is affected.
