Abstract

The invention relates to the technical field of extraction and treatment of biomedical information, in particular to an independent feedback type stomach pace-making device. The independent feedback type stomach pace-making device comprises an MCU (Management Control Unit), a power supply device, a stomach electrical signal collecting module, a stomach electrical signal extracting and analyzing module, a stimulating signal judging module and a stimulating signal generating module. The independent feedback type stomach pace-making device provided by the invention obtains a corresponding stomach wriggling state by extracting a body surface stomach electrical signal and analyzing the information of amplitude, frequency, power, and the like of the signal and judges the generation of a simulating signal; and an electrode acts on a projecting area of the stomach of the surface of a human body, therefore, the relevance between the stomach electrical signal and the stomach pace-making signal is established, independent feedback type stomach pace making is realized.

Description

technical field [0001] The invention relates to the technical field of biomedical information extraction and processing, in particular to a device for extracting electrogastric information from the body surface, autonomously judging the state of gastric peristalsis, feeding back stimulation of the gastric body surface, and realizing gastric pacing. Background technique [0002] Gastrointestinal diseases are common and frequently occurring, accounting for more than 10% of the total population, seriously affecting people's quality of life, and receiving increasing attention and attention from domestic and foreign medical experts. In my country, 50% of gastrointestinal cases are related to abnormal gastric motility. With the in-depth study of the mechanism of cardiac pacing, scientists have wondered whether there is also a pacemaker in the gastrointestinal tract. In 1971, Kelly discovered that the gastric pacing area is located in the upper 1 / 3 of the gastric body, and the sma...
