Patch typed detection device of using myoelectric signal to detect muscle fatigue characterized by giving user a waening via the vibration of the device when the muscle fatigue occurs to user, so that the user may reduce the activity level to avoid muscle from injury
The present invention provides a patch typed detection device of using myoelectric signal to detect muscle fatigue. The device comprises: a main body and a vibration unit, a signal pre-processing electric circuit and a processing unit, which are disposed on the main body. The main body is provided with a patch connector for connecting to the external patch. The signal pre-processing electric circuit may acquire the myoelectric signal from the patch via the patch connector and process a signal treatment for the myoelectric signal to provide the myoelectric information. The processing unit may perform a time-frequency transform for the myoelectric information to generate the myoelectric frequency domain information and may drive the vibration unit to perform vibration when the frequency value in the myoelectric frequency domain information is lower than the threshold. The device uses said action to give user a waening via the vibration of the device when the muscle fatigue occurs to user, so that the user may reduce the activity level to avoid muscle from injury.本發明係提供一種以肌電訊號偵測肌肉疲勞之貼片式偵測裝置。前述之裝置包含本體,以及設於本體之振動單元、訊號前處理電路、以及處理單元。本體上設有用於接合外部貼片之貼片接頭。訊號前處理電路經由貼片接頭以從貼片取得肌電訊號,對肌電訊號進行訊號處理以提供肌電資訊,而處理單元則對肌電資訊進行時頻轉換以產生肌電頻域資訊,並於肌電頻域資訊之中頻率值低於門檻值即驅動振動單元進行振動。本裝置透過上述之運作可對使用者之肌肉疲勞發生時,透過裝置振動,給予使用者警告,讓使用者降低活動量,避免肌肉受傷。1‧‧‧貼片式偵測裝置10‧‧‧本體101‧‧‧第一殼體102‧‧‧第二殼體1020‧‧‧嵌入口103‧‧‧貼片接頭11‧‧‧電路板12‧‧‧電池13‧‧‧通訊模組14‧‧‧通訊傳輸埠15‧‧‧卡榫元件2‧‧‧貼片21‧‧‧貼片連結部
