Electromyogram signal processing system and processing method capable of helping the patient to notify the primary caregiver to provide the care needs and achieving the effect of communication
An EMG (Electromyogram) signal processing system comprises at least one electrode patch, a signal amplification filtering unit, a microprocessor and a sound aid. The electrode patches are arranged on a user to capture the voltage level changes on the body surface of the user and generate a surface EMG acquisition signal. The signal amplification filtering unit is connected with the electrode patches to receive, amplify and filter the surface EMG acquisition signal. The microprocessor is connected with the signal amplification filtering unit to receive and convert the surface EMG acquisition signal into a digital signal, and determine whether the digital signal is greater than a threshold value. With the above-described structure and method, the present invention allows the change of the electrophysiological signal or the EMG signal to be immediately detected by a nearby caregiver, thereby helping the patient to notify the primary caregiver to provide the care needs and achieving the effect of communication.一種肌電訊號處理系統,包括至少一電極貼片、一訊號放大濾波單元、一微處理器及一發聲輔具。該等電極貼片設置於一使用者身上,並擷取該使用者身體表面上的電位變化,產生一表面肌電擷取訊號。該訊號放大濾波單元與該等電極貼片連接,接收並放大濾波該表面肌電擷取訊號。該微處理器與該訊號放大濾波單元連接,接收並將該表面肌電擷取訊號轉換為一數位訊號,判斷該數位訊號是否大於一閥值。藉由上述結構與方法,本發明可讓電生理訊號或肌電訊號變化即時地讓週遭照護者察覺,幫助病人通知主要照護者提供照護需求,而達到溝通之效果。(1)‧‧‧肌電訊號處理系統(10)‧‧‧電極貼片(11)‧‧‧訊號放大濾波單元(12)‧‧‧微處理器(13)‧‧‧發聲輔具
