Abstract

The invention provides a bowel sound acquisition system and acquisition method based on a multi-channel electronic stethoscope, belongs to the technical field of bowel sound auscultation signal processing, and particularly relates to a bowel sound acquisition system and acquisition method based on an electronic stethoscope. The acquisition system and the acquisition method provided by the invention solve the problems that in a bowel sound signal acquisition process, the static electricity of the human body and the friction sound of the skin cause interference to the bowel sound, the effect ofthe bowel sound acquired by a suspended stethoscope head is not ideal, artifacts generated by abdominal exercise of a patient interfere with the bowel sound signal, and the auscultation efficiency ofa single auscultation channel is low. The acquisition system comprises an electronic stethoscope head, a pressurization airbag, an isolation device, a hose, an air pump, an air release valve and a tailor-made belly band. The acquisition system and the acquisition method are mainly used for acquiring the bowel sound signal.

Description

technical field [0001] The invention belongs to the technical field of bowel sounds auscultation signal processing, in particular to a system and method for collecting bowel sounds based on a multi-channel electronic stethoscope. Background technique [0002] Bowel sounds are intermittent rumbling and grunting sounds produced by the friction between intestinal contents and intestinal contents during intestinal peristalsis. The human body produces bowel sounds with different characteristics under different physiological states. Auscultation of bowel sounds is the main means of clinical diagnosis of intestinal diseases. Manual auscultation has the disadvantages of strong subjectivity, time-consuming, and easy misdiagnosis. Electronic auscultation equipment has become the main product to replace manual auscultation because of its advantages of short time consumption and no location restrictions. However, the existing electronic auscultation equipment for bowel sounds has the ...
