Abstract

We describe a low cost, easy to construct monitoring and teaching aid for the oesophageal and precordial stethoscopes. It is constructed from two readily available 'state of the art' integrated circuits. The aid allows more than one observer simultaneously to hear heart and breath sounds, without being acoustically isolated from the other monitoring. In addition it is possible to record from the device to audiotape.

摘要

我们描述了一种用于食管听诊器和心前区听诊器的低成本、易于构建的监测与教学辅助工具。它由两个现成的“先进”集成电路构建而成。该辅助工具能让不止一名观察者同时听到心音和呼吸音，且不会在声学上与其他监测隔离开来。此外，还可以从该设备录制到录音带上。
