Patent ID: 7129845

Claim:
An electrotherapeutic apparatus for programming and memorizing modulated medium frequency carrier waves, which is applied to memorize modulated wave groups for use in deep/shallow positions, physical causes, and therapeutic procedures of diseases to provide with suitable and accurate therapeutic procedures, the electrotherapeutic apparatus comprises: a central processing unit, which is adopted as an operation center of the electrotherapeutic apparatus and cooperated with a program-memorizing unit for storing program (software); a data-memorizing unit, electrically connected with the central processing unit for storing data of modulated wave groups of modulated low frequency waves and extremely low frequency waves (modulated waves) and the therapeutic procedures; a data input unit, electrically connected with the central processing unit for choosing or editing the data of the modulated wave groups stored in the data-memorizing unit; an alarm/output unit, electrically connected with the central processing unit for warning and outputting statuses of the electrotherapeutic apparatus; an editing and display unit, electrically connected with the central processing unit for displaying the data of the modulated wave groups stored in the data-memorizing unit; a signal transformation unit, electrically connected with the central processing unit for performing a digital/analog conversion step on the data of the modulated wave groups so as to form the modulated wave groups; a signal output driving unit, electrically connected with the signal transformation unit for driving the signal transformation unit; a signal output display unit, electrically connected with the signal transformation unit for displaying signal output statuses of the electrotherapeutic apparatus; a signal output actuation unit, electrically connected with the central processing unit and the signal output driving unit respectively, wherein the central processing unit drives the signal output actuation unit to utilize two independent signal output ports through the signal output driving unit to output synchronous signals; and an overvoltage protection unit, electrically connected with the central processing unit and the signal output actuation unit respectively, wherein when the supplied power is unstable or an interference source generates a surge, the signal output actuation unit will be terminated to stop outputting signals to avoid the overvoltage phenomenon.
