Description

Avoid noise interference's bowel sound auscultation device

Technical Field

The utility model relates to the technical field of stethoscopes, in particular to an intestinal sounding auscultation device capable of avoiding noise interference.

Background

Auscultation has been used as a non-invasive test for hundreds of years. And bowel sounds are one of the most important auscultations for abdominal examinations. The incidence rate of intestinal motility disorder diseases is high, such as chronic constipation, irritable bowel syndrome and the like, but the diagnosis of the diseases depends on the subjective feeling of patients more and is greatly influenced by the patients. The examination that can objectively reflect whether intestinal motility is normal is less, and the operation is troublesome, if the colon transmission test needs to carry out abdominal X-ray pictures for many times, the intestinal pressure measurement needs to be put into a pressure measurement device. Meanwhile, some organic diseases such as Crohn's disease and ulcerative colitis are found to be accompanied by abnormal intestinal dynamics. These intestinal motility abnormalities are reflected by bowel sounds, which serve as objective evidence to aid in the diagnosis of these diseases. Because the bowel sounds have irregular characteristics and studies find that the bowel sounds have periodicity of approximately 80-150 minutes, the auscultation time of the bowel sounds is usually longer in order to fully acquire the characteristics of the bowel sounds.

The conventional stethoscope for auscultation of bowel sounds has the defects that long-time monitoring cannot be realized, doctors judge the auscultation to have subjectivity, signals cannot be deeply mined, and the like, and the defects can be overcome due to the appearance of the electronic stethoscope.
