Embodiment Construction

[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, a method of the present invention for measuring the electro-mechanical coupling relationship of gastric dynamics will be further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] A method for measuring the coupling relationship between gastric motility electrical activity and mechanical activity of the present invention, such as figure 1 As shown, the steps are:

[0051] The bioimpedance signal is obtained, and the body surface voltage signal is obtained by being excited by a constant current excitation source, and obtained after a signal conditioning circuit, an amplifying circuit, signal demodulation, and sampling.

[0052] The constant current excitation source, signal condition...

Abstract

The invention relates to a method for measuring the electric-mechanical coupled relation of the gastric motility from the gastric impedance and gastric electric signal, belonging to the biomedical information extraction and process technical field. The synchronic gastric impedance signal and synchronic gastric electric signal are extracted and the correlation coefficient, synchronous coefficient, power variation coefficient and frequency variation coefficient of the two signals are analyzed, the electric-mechanical coupled relation is measure and the coupled relation between the gastric electric pacemaker signal and the gastric movement signal to provide the basis for the gastric motility evaluation.

Description

technical field [0001] The invention relates to the technical field of biomedical information extraction and processing, in particular to a method and a corresponding device for measuring the coupling relationship between gastric dynamic electrical activity and mechanical activity in extraction of gastric impedance and gastric electrical signals. 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. [0003] The function of gastric motility is completed by the coordinated movement of gastric smooth muscle under the regulation of nerves, body fluids and other factors. It includes the functions of accommodation, mixing, propulsion, emptying and barrier after food e...
