肠鸣音分析仪的研制

The Study of Intestinal Sounds Analyzer

介绍了肠鸣音分析仪的硬件设计和软件设计,该系统由高灵敏度检测电路和微型计算机组成,用它可对肠鸣者进行定性定量分析,并准触地显示、记录、存储分析结果。本文还对肠鸣音的时域和频域实验结果作了讨论。

This paper introduces the hardware and the software of the intestinal sounds analyzer. The analyzer consists of a high sensitive acquiring circuit and a microcomputer. It can sensitively and rapidly acquire a set of parameters including time domain and frequency domain. It also can display and record the analyzed results completely and accurately. This paper also discusses the methods of frequency spectrum,and summarizes the characteristics of intestinal sounds from clinic experiments.
