Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical analysis, in particular to a portable intestinal sound real-time monitoring device and dynamic analysis system. BACKGROUND

[0002] Intestinal sound is one of the important physiological signals of human body, which is caused by the friction and impact between the small intestinal movement and the intestinal contents, and is a reflection of the small intestinal movement state. In the pathological state, the intestinal sound of the patient often changes, showing hyperactivity or weakening, so the clinician often judges the patient's condition by the changes of the patient's abdominal intestinal sound.

[0003] However, the traditional intestinal sound detection mainly relies on the doctor using the stethoscope to manually listen, and relies on the doctor's hearing and experience for judgment. This method is highly subjective, and the result is easily affected by the doctor's personal experience and technical level, lacking objective and standardized judgment criteria. Moreover, the manual listening method cannot be continuously monitored for a long time, and can only be checked at a specific time point, making it difficult to capture the dynamic changes of intestinal sound and unable to provide comprehensive diagnostic information. In addition, in the process of real-time monitoring of intestinal sound in daily life, when the abdomen of the person being detected is squeezed (such as the waistband is too tight or the abdomen is squeezed by abdominal exercise), the intra-abdominal pressure will rise, which will cause the detection instrument to produce deviation in the detection result of intestinal sound.

[0004] In view of the above technical defects, the present application provides a solution. SUMMARY

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0067] S43, a preset health assessment threshold of the bowel sound is obtained, and when the evaluation index is greater than or equal to the health assessment threshold, it indicates that the health of the detected person is abnormal, and the health abnormal information is sent through the information transmission unit for early warning, and the detected person is suggested to go to the hospital for further examination, otherwise, it indicates that the detected person is healthy.
