Automatic feed state interval correction device and correction method

Abstract

The invention provides an automatic feed state interval correction device and method. The device comprises an electrode catheter, a data recorder and a feed state interval correction unit. The electrode catheter comprises N impedance sensors, wherein N refers to a positive integer larger than 1. The data recorder comprises a data storage unit, a key unit and a microprocessor. The impedance sensorsacquire esophagus impedance information, and an output end of the impedance sensor is connected with an impedance information input end of the microprocessor. The key unit records symptoms and / or states of an examinee, an output end of the key unit is connected to the microprocessor, and the microprocessor is in bidirectional connection and communication with the data storage unit. The feed stateinterval correction unit corrects feed state markers according to data information in the data storage unit. The automatic gastroesophageal swallow recognition device is simple in structure, accuracyin feed state interval correction can be improved, and correctness and objectiveness in later reflux analysis are guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device and a correction method for automatic correction of eating state intervals. 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 dur...

Problems solved by technology

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

Usually, the method of excluding the eating interval is through the patient’s manual recording on the recorder. However, when the patient records symptoms or status, he often forgets to operate or does not strictly follow the operation guideline, which brings about problems in recording the eating status. Inaccurate, because the impedance curve signal in the eating interval is relatively complex, which brings challenges to the subsequent automatic reflux analysis, and it is easy to form more reflux misjudgments. Therefore, the correct marking of the eating state interval is the impedance ph reflux monitoring Prerequisites for subsequent automatic analysis of system regurgitation

However, the current impedance ph reflux monitoring often needs to be edited manually by the examiner based on the status of the patient's records, which brings additional work to the doctor.
