Problems solved by technology

However, gastroscopy requires the stomach to be in an empty state during the examination, which requires the patient to fast, and even some patients must have gastric lavage before the gastroscopy, which brings pain to the patient
In addition, gastroscopy is an invasive operation, and many patients have concerns about the degree of safety and disinfection effect of gastroscopy, and feel fear
The contraindications of gastroscopy also make it unsuitable for some patients

Embodiment Construction

[0044] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] In the following description, how to preprocess the signals collected by the electrodes (essentially amplifying and filtering the signals by hardware circuits), you can refer to Chinese Patent Application No. 89205695.9, which was issued by Zheng Jianhua on June 1, 1989 The application was filed and published on September 19, 1990, and reference may be made to Chinese Patent Application No. 200710124464.3, which was filed on November 13, 2007 by the Shenzhen Research Institute of Tsinghua University and published on February 25, 2009. These applications are incorporated herein by reference. However, the gastroelectric signal preprocessing methods disclosed in Chinese patent applications No. 89205695.9 and No. 200710124464.3 do not constitute a limitation to the present invention. Any conventional method of gastric electrical signal pre...

Abstract

The invention discloses a method for reconstructing stomach surface serosa electrogastrogram signals according to body surface electrogastrogram signals, which belongs to the field of signal processing. The method includes determining the placement position of an electrode when body surface electrogastrogram is measured at first; then acquiring a body surface electrogastrogram signal and processing the body surface electrogastrogram slow-wave signal into digital signals; and finally reconstructing a stomach surface serosa electrogastrogram signal according to the body surface electrogastrogram signal. The method is used for diagnosing stomach diseases by means of detecting body surface bioelectricity information of the stomach of a patient, and accordingly conditions of functions of the stomach of the patient are evaluated.

Description

technical field [0001] The invention belongs to the field of signal processing, in particular to a detector for diagnosing gastric diseases and evaluating gastric function by detecting the bioelectrical information of the stomach on the body surface. Background technique [0002] Since Alvarez, an American physiologist, first recorded gastric electrical activity from the surface of the human abdominal wall, that is, electrogastrogram (EGG), many scholars have tried to use gastric electricity as the biological function index of the stomach to study the physiological and pathological laws of the stomach. , as an objective index for the diagnosis and curative effect judgment of gastric disease patients. At present, an eight-lead intelligent gastrointestinal electrograph has appeared clinically, which can detect gastric electrical signals synchronously at one time. [0003] Gastrointestinal electrographs on the market use the collected body surface electrogastric signals to sta...
