Active multipoint intestine peristalsis monitoring device for increasing borborygmus differentiation degree

Abstract

The invention discloses an active multipoint intestine peristalsis monitoring device for increasing borborygmus differentiation degree. The active multipoint intestine peristalsis monitoring device comprises an intestine peristalsis monitoring signal collecting module, a borborygmus processing module, an acoustical signal outputting module, a human-computer interaction module and a power source. The intesine peristalsis monitoring signal collecting module is composed of a striped abdomen wrapping collection device and is responsible for collecting intestine peristalsis monitoring signals in a multidirectional long-time manner, converting the same into digital signals and sending out pulse ultrasonic signals to simulate finger rapping effect when borborygmus generation needs assistance; the borborygmus processing module extracts borborygmus from the collected intestine peristalsis monitoring signals and providing frequency of borborygmus appearing in each minute; the acoustic signal outputting module reducing borborygmus signals after being processed by the borborygmus processing module into acoustic signals to be played; the human-computer interaction module manually controls the device to be on-off and displays a processing result of the borborygmus processing module. The active multipoint intestine peristalsis monitoring device enables the borborygmus monitoring process to be more intelligent, safe and efficient.

Description

technical field [0001] The invention relates to sensor technology and voice signal processing technology, in particular to an active multi-point intestinal peristalsis monitoring device for improving the discrimination of bowel sounds. Background technique [0002] Bowel sounds, when the bowel is peristaltic, the gas and liquid in the intestinal tube flow with it, producing an intermittent grunting sound or the sound of air passing through water. The gastrointestinal tract is like a "bottle" that is only partially filled with water. If the thin liquid is added with gas, coupled with the movement of the gastrointestinal wall itself (gastrointestinal peristalsis), the stomach contents will move. Bowel sounds are produced. The peristalsis of the human body is generally not much related to gender, it is about 4 to 5 times a minute, and its frequency, sound and tone change greatly. It is frequent and obvious after a meal, and sparse and weak when resting. Bowel sounds of normal...

Problems solved by technology

[0012] Aiming at some existing problems in the field of bowel sound monitoring and diagnosis, such as long auscultation time, contact with patients may lead to the spread of disease, single collection location, passive collection form, and it is difficult to hear different characteristics of the collected bowel sounds even if they are played back, etc. Problem, the present invention aims to propose an active multi-point bowel movement monitoring device that improves the discrimination of bowel sounds. The multi-point acquisition device is used to monitor bowel movement signals in different parts of the intestinal tract at the same time, and no bowel sounds are collected at a specific time Actively give external incentives to stimulate the intestinal tract by imitating finger taps; extract useful bowel sounds from the monitoring signal, and use digital signal processing methods to expand the frequency domain to the sensitive frequency band of the human ear and at the same time unmasking, become Voice signals suitable for human ears to clearly recognize, making the monitoring process of bowel sounds more intelligent, and doctors auscultating bowel sounds more objectively, in a shorter time, more efficient and safer
