臨床的產檢中，子宮收縮信號和胎兒心跳率是非常重要的生理資訊；醫護人員可以藉由測量這些參數，來了解孕婦與胎兒的狀況。異常的數值變化，通常是早產或流產的警訊。但醫護人員卻只能在產檢時，藉由儀器才能了解孕婦的子宮收縮情況，也因此無法於生理參數異常時，第一時間內提供孕婦必要之協助。智慧型手機不但具有傳統PDA與GSM手機的功能，並提供藍芽傳輸、顯示介面與簡易的程式撰寫，另外長時間的待機與行動無線網路之功能，更適合用於生理參數之長期監控。有鑑於此，本研究希望建立一套可攜式長時監控孕婦子宮收縮系統，利用藍芽技術，並結合智慧型手機作長時監測。
系統主要架構可分為兩個部份；第一部份為生理訊號之擷取，利用單晶片(MSP430F169)分析處理，並透過藍芽模組，將數值變化傳送到手機上。第二部份為智慧型手機的即時訊號顯示、儲存孕婦的生理參數變化，並在參數持續異常時，經由手機撥號，在最短時間內聯絡醫護中心，以達到即時救護的功能。

Uterine contraction (UC) and fetal heart rate (FHR) are two important parameters to check the fetal status on prenatal diagnosis, the abnormal UC and FHR will cause premature delivery or miscarriage. Therefore, how to develop a long-term monitoring system of uterine contraction and FHR become an important issue on obstetrics and Gynecology.
The aim of this study is to set up a long-term monitoring system. A wireless portable device based on micro-controller (MSP430) is used to acquire the physiological signals and transmit them to the smart phone via the Bluetooth wireless technology. The acquired signals and waveform are displayed on smart phone’s screen and saved for further processing. If a possibility of premature delivery occurs, system will send an emergency call for medical help automatically, to provide medical service immediately. This system highly promotes the convenience of both the pregnant women and the medical personnel and further improves the quality of health care.
