Industrial testing method for working stability of digestive tract dynamic detector under vibration state

Abstract

The invention provides a method for industrially detecting the working stability of a digestive tract motion detector in a vibrational state. The digestive tract motion detector is born by utilizing a cyclic conveying base to perform online detection, the cyclic conveying base drives the digestive tract motion detector to perform cyclic vibration, a vibration frequency cycle range is 3Hz-20Hz-15Hz-20Hz-30Hz-15Hz-3Hz, the cycle frequency is 12 cycles per minute, and amplitude is 0.4 mm. During cyclic vibration, the cyclic conveying base inputs sine wave signals of 150 microvolts and 0.05 Hz to the gastrointestinal electric part and records a gastrointestinal electric part detection result A output by the digestive tract motion detector. The cyclic conveying base inputs the pressure ranging from -100 mmHg to 450 mmHg to a pressure detection part and records a pressure detection part detecting result B output by the digestive tract motion detector. The method is suitable for industrial online detection, can automatically complete the whole detection process and is high in detection efficiency, detection value coverage is comprehensive, detection environment change combination change is diversified, and the reliability of detection results is high.

Description

technical field [0001] The invention relates to the field of digestive tract power detection equipment, in particular to an industrial detection method for the working stability of a digestive tract power detector in a vibrating state. Background technique [0002] Gastrointestinal motility testing is a safe, convenient, non-invasive, and high-diagnostic technique for the diagnosis of gastrointestinal diseases and postoperative functional evaluation. Digestive tract motility detection methods mainly include esophageal pressure detection, anorectal pressure detection and gastrointestinal electrogram detection. The digestive tract motility detector is the key equipment for the digestive tract motility test. The performance of the detector and the stability of its working performance in a specific environment are directly related to the reliability of the test data and play a key role in the doctor's diagnosis. Sexuality. In the prior art, in mass-produced digestive tract dyn...
