藍芽式動態心律監測儀

Applying Bluetooth on Monitoring the Dynamic Heart Rate

在運動時的心率資訊是監控心肺功能的一項重要條件，因此便因應出各種方法去量測心率在規律性運動時變化，包含圖形式容積描繪法、阻抗量測法與胸導層的ECG量測技巧等等。不過這幾種量測法有其缺點，如:測量時人體必須用導線與儀器連接的不便，可能妨礙到量測的準確性。這次的研究目標便是改良此缺點，發展輕便型的心率量測裝置，利用藍芽模組做無線傳輸，達到可移動的目的。原理是利用一個壓電式的感測器，固定在受測者的頭部，偵測因為心跳而造成的動脈搏動，在用濾波器和檢波器從ECG信號中取出心率值，經過微處理器計算，並傳送到個人電腦（PC）的無線藍芽模組，量測心率的結果用圖形的方式顯示在個人電腦上，並可反應出此次運動所量測到的相關資訊。

A ccording to American Heart Association’s reports, a man wants to keep a healthful heart,then he must exercise three times in a week, and the sport’s time is thirty minutes at least. In this sport’stime, the heart rate must raise above the 60~90 percent of heart rate peak. The training heart rate is therange between 60 and 80 percent of the heart rate peak in 1991. The senses of the exercises are not rightfor the major people in our country. They always think that the sports are the sweeping the floor,climbing the stairs or swing the arms. Moreover, they think that the exercises are only to sweat. Thesesenses are all wrongs according American Sport Association’s reports. Therefore, we have designed anew device that can monitor the heart rate in the exercise with the wireless technique of blood tooth. Inthe exercise, the heart rate is transported to a notebook in real time, and the monitor displays the real-time values and alarms to the users.
