The present invention relates to a high frequency treatment apparatus having a circuit configuration in a hardware manner and a program configuration in a software manner to prevent skin from being burned due to spark. The high frequency treatment apparatus includes a human body contact detection unit which outputs, to a control unit, a detection signal, which detects an electrical contact status between a plate and a magnetic member, which are high frequency output electrodes, and a human body in real time. The control unit has a program routine which is performed to control by lowering voltage or blocking high frequency output which is outputted from a high frequency output unit when the detection signal exceeds a reference voltage by determining whether the human body contact detection signal, transmitted from the human body contact detection unit, exceeds the predetermined reference voltage or not. In addition, the human body contact detection unit extracts the human body contact detection signal using change of current, which flows in one place selected from a power input line and a power output line of a power unit supplying power to a high frequency amplification unit and a high frequency output unit having great changes of current consumption among the entire circuits. The reference voltage, which is programmed in the control unit in advance, is configured to control to block the high frequency output and to gradually increase the output level in real time by comparing to, in real time, the voltage levels of the human body contact detection signal, which are provided as a plurality of reference voltages, predetermined in voltage levels, to be inputted into the control unit.COPYRIGHT KIPO 2016본 발명은 스파크로 인한 피부 화상을 방지할 수 있도록 하드웨어적 회로 구성과 소프트웨어적 프로그램 구성을 가지는 고주파 치료기에 관한 것으로서,본 발명은 고주파 출력 전극인 도자 및 상기 플레이트과 인체 간의 전기적 접촉상태를 실시간 감시하는 감지신호를 제어부로 출력하는 인체접촉감지부를 포함하여 구성되며, 상기 제어부는 상기 인체접촉감지부에서 전송된 인체접촉 감지신호를 기초로 미리 설정된 기준 전압의 초과 여부를 판단하여 기준 전압을 초과할 경우 고주파출력부에서 출력되는 고주파
