Abstract

The invention discloses a system for processing animal gastrointestinal mobility signals. The system comprises a data collection unit and a data processing unit. The data processing unit comprises a preprocessing unit, a baseline drift removing unit, an abnormal data identifying and removing unit, a contraction cycle positioning unit and a gastrointestinal dynamic calculating unit. The invention further discloses a method for processing the animal gastrointestinal mobility signals. The method includes the steps of data collection, preprocessing, baseline drift removal, abnormal data identification and removal, contraction cycle positioning and gastrointestinal dynamic calculation. By the system and the method, existing low efficiency and inaccuracy in manual waveform observation and manual calculation of gastrointestinal dynamics indexes such as wave number, amplitude and dynamic index are changed, and calculation speed of each gastrointestinal mobility performance index can be greatly improved.

Description

technical field

[0001] The invention relates to the technical field of electrophysiological signal processing, in particular to a processing method for measuring animal gastrointestinal motility signals. Background technique

[0002] The important function of gastrointestinal motility is to push food from the mouth to the anus. This process is completed by the regular contraction and relaxation of the longitudinal and circular muscles of the gastrointestinal wall. There are periodic phase changes in the gastrointestinal motility of humans and dogs, which is called the migrating motor complex (MMC) during the digestive period. In the awake and fasting state, the MMC of the gastrointestinal tract always proceeds according to the cycle of four phases. Phase I showed no contraction, lasting 40-60 minutes, phase II had intermittent and irregular contraction, lasting 30-45 minutes, phase III showed intensive contraction, lasting 5-12 minutes, and phase IV was a transitional phase...
