A digestive tract power detection system

Abstract

A digestive tract power detection system relates to the field of digestive tract power detection, including an eight-lead gastrointestinal electrogram detection system, a pressure detection system and a software control system. The pressure detection system includes an esophageal pressure detection system and anorectal pressure detection system. Through the software control system, the instrument conducts two-way data transmission between the eight-lead gastrointestinal electrogram detection system, esophageal pressure detection system and anorectal pressure detection system, and realizes the collection of esophageal dynamic detection, anorectal dynamic detection and eight-lead gastrointestinal electrogram detection Digestive tract motility detection system with three functions in one. The best effect is that the digestive tract dynamic detection system embodies the highly integrated circuit technology of the gastrointestinal electrogram detection system and pressure detection system, and integrates signal processing circuits such as signal amplification, active filtering, feedback and control, power amplification and A / A series of circuits such as D conversion are integrated on a computer-specific detection card; and many information processing and automatic control technologies such as electrophysiological signal processing technology, pressure source constant pressure control technology of pressure detection system, automatic control software and data analysis are adopted. Processing technology and database management technology bring great convenience to the diagnosis and research of digestive tract motility diseases, and more accurate and comprehensive diagnosis and research of digestive tract motility diseases.

Description

technical field [0001] The invention relates to the field of digestive tract dynamics detection, in particular to a digestive tract dynamics detection system integrating three functions of esophageal dynamics detection, anorectal dynamics detection and eight-lead gastrointestinal electrogram detection. Background technique [0002] Gastrointestinal motility testing is a safe, convenient, non-invasive, and high-diagnostic technique for the diagnosis of gastrointestinal diseases and postoperative functional evaluation. Digestive tract motility detection methods mainly include esophageal pressure detection, anorectal pressure detection and gastrointestinal electrogram detection. At present, only a few manufacturers have solved the technology of combining one or two of these functions, and have launched related products for clinical application that only have the functions of anorectal pressure detection or both esophageal pressure and anorectal pressure detection. Since the te...
