摘要：
The present invention relates to a monitoring device and a monitoring method of stenosis. The monitoring device comprises: a sound detecting unit for eliminating noise and collecting a sound signal from a blood vessel a sound signal transforming module for transforming the sound signal into an electric signal and a micro processing unit for receiving and calculating the electric signal to obtain a time-frequency domain characteristic figure, and then outputting a comparison result. The sound detecting unit eliminates the external noise to improve the accuracy of sound signal retrieval, serving to monitor stenosis.本發明關於一種管體窄化監測裝置及其監測方法,以解決習知管體之聲音監測易受噪音干擾及解析不佳之缺點。本發明之管體窄化監測裝置包括:一音訊感測單元,用以消除噪音干擾並收集一管體之一聲音訊號;一音訊轉換模組,用以將該聲音訊號轉換為一電信號;一微處理器,用以接收該電訊號並經運算處理獲得一時域-頻域特徵圖案; 一圖案辨識模組,用以比對該時域-頻域特徵圖案與一標準化時域-頻域特徵圖案資料,並輸出一比對結果。藉由該音訊感測單元消除外部噪音干擾以提高該管體之聲音訊信號擷取的精確性,作為監測管體窄化之用途。(1)‧‧‧管體窄化監測裝置(11)‧‧‧音訊感測單元(111)‧‧‧音訊探頭(112)‧‧‧隔音部(1121)‧‧‧消音層(12)‧‧‧音訊轉換模組(13)‧‧‧微處理器(14)‧‧‧圖案辨識模組(15)‧‧‧顯示單元(16)‧‧‧前置過濾放大模組(17)‧‧‧資料輸入模組(18)‧‧‧無線傳輸模組(19)‧‧‧驅動電源
