摘要
目前歐美日等醫療先進的國家的官方與民間都已經極力廣泛在公共場所備置自動體外除顫器，更朝著讓有心臟驟停的高風險病患家中都能備有自動除顫器的方向努力，但是要能廣設自動除顫器的先決條件之一是設法降低量產成本與售價，而本論文研究自動體外除顫器之系統設計是使用低成本的方式研發，且跟各國市售產品達到相同功能之自動體外除顫器。 自動體外除顫器的系統架構主要可分為兩大部分，第一部分主要為自動體外除顫器央控制器，主要是以內部程式架構控制周邊系統，第二部分為高壓充放電擊電路與電極貼片，電擊脈衝主要是藉由此電路充電完成治所需的能量，再藉由電極貼片所連接的電極現將產生的電擊脈衝傳遞電能給予病患放電，系統主要這兩大主軸。 自動體外除顫器系統保護也極為重要，在設計之時也必須考量到保護操作者以及人員的安全，以及高壓電擊之後是否會損毀到內部系統電路，導致系統無法正常運作，在本論文內會深入探討如何保護系統與人員安全，且設有系統自我檢測功能，而自我檢測功能是以防備不時之需要使用此自動體外除顫器時，確定系統內部功能是正常運作。 本論文所使用的微處理器主要為Analog Devices公司之產品 BF518F晶片為整體系統核心，並有效的設計出系統內部電路，而系統內部又可分為各區塊子系統，每個子系統設計出來需經過詳細的驗證，將每個子系統與微處理器整合起來運作，再藉由微處理器內部程式設計系統流程，而整個系統可以完整擷取到病患心電圖訊號，並可以成功判別出正常心律與心室顫動兩者之間心律差異性，且給予操作者當下最適當的操作提示。

Official and civil society of the countries of Europe and the United States and other advanced medical both strongly widely prepared in public places, home automated external defibrillators, more toward the home of high-risk patients in cardiac arrest can be equipped with automatic defibrillators both direction one of the prerequisites for effort, but to be able to establish more automatic defibrillator is to try to reduce the low-volume production costs and selling prices, while automated external defibrillator system design in this study is to use a low-cost way to R & D, and with countries City the sale of products to achieve the same functionality of the automated external defibrillator. Automated external defibrillator system architecture can be divided into two parts, the first part of the automated external defibrillator central controller, internal program architecture control peripheral systems, the second part is the circuit with the electrode of the high voltage charge and discharge electric shock patch, shock pulse is primarily by this circuit charging the energy required to complete the cure, then the electrodes are connected by the electrode patches will now be generated shock pulse transfer power given patient discharge system mainly two spindle. Automated external defibrillator system protection is extremely important in the design must take into account the protection of the operator as well as the safety of personnel, as well as high-voltage electric shock will damage to the internal system circuit will cause the system not working properly, in the papers depth discussions on how to protect the system and personnel safety, and a system self-test function, self-detection function is preparedness for contingencies to use automated external defibrillators, within the system function is normal operation. The microprocessor used in this thesis for the Analog Devices Company. The product BF518F wafer for the core of the overall system, and design a system of an internal circuit, while the inside of the system can be divided into each block subsystem, each subsystem design required After detailed verification of each subsystem with microprocessor integrated operation of the by the microprocessor internal programming system processes, and the entire system can complete capture patient ECG signals, and can successfully distinguish a normal heart rhythm ventricular fibrillation rhythm differences between the two, and give the operator the moment the most appropriate operating tips.
