Technical Field

The embodiment of the invention relates to the technical field of medical instruments, in particular to a method and a device for detecting gastrointestinal electric signals, detection equipment and a storage medium.

Background

With the advent of gastrointestinal motility detection technology, gastrointestinal electricity has developed into an important branch of electrophysiology, and methods for detecting gastrointestinal electricity, like concentric Electrograms (ECGs) and electroencephalograms (EEG), use skin electrodes to record from the body surface of the abdominal wall of a human body; when the skin electrode is placed at a corresponding detection point of a gastrointestinal part, gastrointestinal electric signals are recorded and serve as objective bioelectricity indexes of gastrointestinal function activities. According to the change of the gastrointestinal electrical waveform and parameters, a diagnosis reference and a curative effect judgment of gastrointestinal diseases can be made for a patient. For example, electrogastrograms are objective bioelectrical indicators of gastric functional activity, in which gastric electrical activity is recorded from the body surface of the abdominal wall of a human body by means of surface electrodes; the reference diagnosis can be made for the patient with gastropathy according to the change of electrogastrogram parameters, and the treatment and the drug effect can be evaluated. With the intensive research on the gastric electrology and the intestinal electrology of people, the gastrointestinal electrical signals with weak surface and low frequency of a human body are guided out, and interference factors are eliminated, so that the recording of ideal gastric electrograms and intestinal electrograms becomes possible. The current common detection means is gastroscope and enteroscope detection, which causes great damage to the body and the diseased part of a patient, and with the appearance of gastrointestinal motility detection technology, gastrointestinal electric signals are collected noninvasively through skin surface electrodes, and are recorded after host amplification and filtering processing to serve as objective bioelectricity indexes of gastrointestinal function activities.

In the existing detection method of gastrointestinal electrical signals, the original biological function signals including biological electrical signals and biological non-electrical signals introduced by a sensor are firstly amplified, filtered and the like, then the processed signals are digitized through analog-to-digital conversion and the digitized biological function signals are transmitted to the inside of a computer, the computer receives the digital signals transmitted from biological signal amplification and acquisition hardware through special biological function experiment system software, and then the received signals are processed in real time.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:

in the existing gastrointestinal electric signal detection method, the detection condition of the gastric electric signal corresponding to the original gastric electric signal and the detection condition of the intestinal electric signal corresponding to the original intestinal electric signal are preset, and because the gastric electric signal and the intestinal electric signal of a subject in a pre-meal state are greatly different from the gastric electric signal and the intestinal electric signal in a post-meal state, the existing gastrointestinal electric signal detection method detects the gastric electric signal according to the fixed gastric electric detection condition and also detects the intestinal electric signal according to the fixed intestinal electric detection condition, so that the accuracy of the detection result cannot be ensured. There is therefore a need to overcome this problem in some way as far as possible, but there is no effective solution in the prior art.

According to the detection equipment for gastrointestinal electric signals, provided by the embodiment of the invention, the detection equipment respectively collects the original gastric electric signals and the original intestinal electric signals of a subject through the first electrode plate and the second electrode plate; then the detection equipment determines the stomach electric signal detection condition corresponding to the original stomach electric signal and the intestinal electric signal detection condition corresponding to the original intestinal electric signal according to the dining state of the subject; when the original gastric electrical signal meets the gastric electrical signal detection condition, the detection equipment detects the original gastric electrical signal according to the gastric electrical signal detection condition and sends a gastric electrical detection result corresponding to the original gastric electrical signal to an upper computer through a gastric electrical detection channel corresponding to the original gastric electrical signal; when the original gastrointestinal electrical signals meet the gastrointestinal electrical signal detection conditions, the detection equipment detects the original gastrointestinal electrical signals according to the gastrointestinal electrical signal detection conditions, and sends the gastrointestinal electrical detection results corresponding to the original gastrointestinal electrical signals to the upper computer through the gastrointestinal electrical detection channels corresponding to the gastrointestinal electrical signals.
