Automatic identification of gastroesophageal swallowing device and method

Abstract

The invention provides a gastroesophageal swallowing automatic recognition device and method. The device comprises an electrode catheter, a data recorder and a swallowing detection unit, the electrodecatheter comprises N impedance sensors, wherein N is a positive integer greater than 1; the data recorder comprises a data storage unit, a button unit and a microprocessor, the impedance sensors collect esophagus impedance information, the output end of the impedance sensor is connected with the impedance information input end of the microprocessor, the button unit records symptoms and / or state of an examination receiver, the output end of the button unit is connected with the microprocessor which is bidirectionally connected with the data storage unit and is in communication with the same, and the swallowing detection unit performs swallowing recognition according to data information in the data storage unit. The device is simple in structure and can accurately recognize swallowing, anda basis is provided for ensuring accuracy of subsequent automatic reflux analysis result.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device and method for automatically identifying gastroesophageal swallowing. Background technique [0002] At present, for the detection of gastroesophageal reflux disease, an impedance-pH combined monitoring system is increasingly used in clinical practice to monitor the gastroesophageal reflux condition of patients. The monitoring system can usually record the symptoms and states of the patient, and record different symptoms and states through the corresponding keys of the patient on the recorder. In the patent document with application number 2015106002908, the analysis of esophageal impedance during reflux is disclosed. Through the analysis of esophageal impedance and esophageal pH value, reflux events are detected. However, the analysis of esophageal impedance here should be required to be If it is not in the eating interval, the eating interval should be excluded during th...

In the patent document with application number 2015106002908, the analysis of esophageal impedance during reflux is disclosed. Through the analysis of esophageal impedance and esophageal pH value, reflux events are detected. However, the analysis of esophageal impedance here should be required to be If it is not in the eating interval, the eating interval should be excluded during the entire analysis process, otherwise it will affect the results of automatic analysis

However, the way patients manually record on the recorder often has errors and errors in the eating interval, and the deviation often exceeds a few minutes or more, resulting in inaccurate automatic reflux analysis results
