摘要：
The present invention relates to a magnetic plethysmography measuring device using a time varying magnetic field. Specifically, the magnetic plethysmography measuring device comprises an oscillator module which applies a time-varying magnetic field to a blood vessel through a coil adjacent to the blood vessel and produces a detection signal in which an inductance change the coil by a blood flow inside the blood vessel which is influenced by the time-varying magnetic field is reflected and a signal processing module which produces pulse wave data by processing the detection signal. The present invention relates to a magnetic plethysmography measuring method using a time varying magnetic field. More specifically, the magnetic plethysmography measuring method comprises a (1) step of applying a time-varying magnetic field to a blood vessel through a coil adjacent to the blood vessel a (2) step of detecting of a detection signal in which an inductance change of the coil by a blood flow inside of the blood vessel influenced by the time-varying magnetic field is reflected and a (3) step of producing pulse wave data by processing the detection signal. According to the magnetic plethysmography measuring device using the time varying magnetic field and the method thereof suggested by the present invention, a blood flow can be measured conveniently accurately with an electromagnetic method by using an oscillator module without an additional sensor by producing pulse wave data after detecting an inductance change of a coil by a blood flow influenced by the time varying magnetic field. Moreover, a magnetic field treatment can be executed without an additional blood flow measuring device in the magnetic field treatment and a pulse wave can be measured at the same time.COPYRIGHT KIPO 2015본 발명은 시변자계를 이용한 자기용적맥파 측정 장치에 관한 것으로서, 보다 구체적으로는 혈관에 인접한 코일을 통해 상기 혈관에 시변자계(time-varying magnetic field)를 인가하고, 상기 시변자계의 영향을 받은 혈관 내부의 혈류에 의한 상기 코일의 유도용량(inductance) 변화가 반영된 검출 신호를 생성하는 발진(oscilla
