多用戶無線聽診系統及教學之創意設計

The Innovative Design of Multiuser and Wireless Auscultation System and Teaching

本論文之目的在實現理想的聽診教學實習系統，希望同時顧及病患的隱私權以及提升實習醫師的學習成效。本系統的創意設計在於僅須透過教師的聽診主機聽診，便能即時將病患的心肺音訊號以無線方式同時傳送至八位實習醫師的無線耳機中。更有甚者，系統也能同步加入教師透過麥克風的講解，讓實習醫師能夠很清楚的對照病患心肺音以及教師的訊號解說，不致發生傳統聽診教學中，教學不便以及產生誤解的情形。如此一來，本系統可以降低在聽診器臨床教學時對聽診對象的打擾，並大幅提昇聽診器臨床教學的效率。在病患的心肺音訊號方面，利用放大及濾波功能之硬體電路設計，提供心音、肺音、及心肺音三種訊號，醫生可即時進行切換選取，將大有助於心、肺臟疾病之診斷。

This paper presents an innovative design of auscultation system and teaching, which can not only improve patient privacy but also enhance the learning efficiency of interns. The teacher’s auscultation host can wirelessly transmit the patient’s heart sound and lung sound signals to eight intern’s earphones in real time. Furthermore, the teacher’s vocal explanation is synchronously added so that interns can fully understand about the teacher’s instruction. It greatly avoids the inconvenience and misunderstanding in traditional auscultation system and teaching. In conclusion, the proposed system can substantially reduce the resulting disturbance to patients in clinical auscultation teaching. On the other hand, the learning efficiency in clinical auscultation teaching is greatly improved. Thanks to the amplification and filtering design of the hardware circuit, the presented system provides heart sound, lung sound, and heart-lung sound, so that physicians can instantly switch selection to greatly facilitate the diagnosis of heart and lung diseases.
