Abstract

Due to anesthesia loss of gastrointestinal motility is a common situation for patients who underwent abdominal surgery. The aim of this study is to present the bioacoustic sensor system developed for real time detection of recovery of gastrointestinal tract motility by observing bowel sounds and for bowel sound signal analysis. Different than other studies, in this study, in order to be able to attenuate environmental noise, bowel sounds were observed using two microphones. Bowel sounds were observed between 100 Hz and 1 kHz with maximum amplitude of 20mV. The signal was amplified 121 times and final signal amplitude was between 0-2, 4V. Similarly, environmental noise observed by the second microphone was amplified. Both of the signals were digitized using 12 bit analog digital converter of the ZigBee module (JN5139-Z01) and were transferred with wireless connection. With the developed software, spectral and temporal properties were obtained and presented in real-time. Finally, a stethoscope shaped box was designed for easy use of the sensor system.

用于自动检测肠道声音的无线生物声学传感器系统

由于麻醉导致胃肠运动障碍是腹部手术患者的常见情况。本研究的目的是介绍通过观察肠道声音来实时检测胃肠道运动恢复并进行肠道声音信号分析的生物声学传感器系统。与其他研究不同的是，在本研究中，为了能够减弱环境噪声，使用两个麦克风观察肠道声音。肠音在100hz和1khz之间，最大振幅为20mV。信号放大121倍，最终信号幅值在0 ~ 2.4 v之间。同样，第二个麦克风观察到的环境噪声被放大。两个信号均采用ZigBee模块(JN5139-Z01)的12位模数转换器进行数字化处理，并通过无线连接进行传输。利用开发的软件，实时获取并显示了光谱和时间特性。最后，为了便于传感器系统的使用，设计了一个听诊器形状的盒子。
