An active multi-point peristalsis monitoring device for improving the discrimination of bowel sounds

Abstract

The invention discloses an active multi-point bowel movement monitoring device for improving the distinction of bowel sounds, which comprises a bowel movement monitoring signal acquisition module, a bowel sound processing module, a sound signal output module, a human-computer interaction module and a power supply; The signal acquisition module is composed of a band-shaped wrapping acquisition device, which is responsible for multi-directional and long-term acquisition of intestinal peristalsis monitoring signals, and then converts them into digital signals. effect; the bowel sounds processing module extracts bowel sounds from the collected bowel movement monitoring signals, and gives the frequency of bowel sounds per minute; the sound signal output module restores the bowel sounds signals processed by the bowel sounds processing module The sound signal is played; the human-computer interaction module manually controls the switch on and off, and displays the processing result of the bowel sound processing module. The invention makes the bowel sound monitoring process more intelligent, safer and more efficient.

Description

technical field [0001] The invention relates to a sensor technology and a voice signal processing technology, in particular to an active multi-point bowel movement monitoring device for improving the discrimination of bowel sounds. Background technique [0002] Bowel sounds are the gas and liquid flowing in the bowel when the bowels move, producing an intermittent grunting sound or the sound of gas passing through water. The gastrointestinal tract is like a "bottle" filled with only part of the 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. In this process Bowel sounds were produced. Human bowel movements generally have little to do with gender, about 4 to 5 times per minute, and their frequency, sound and pitch vary greatly, frequent and obvious after meals, and sparse and weak during rest. The bowel sounds of normal people are usually difficult to f...

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
