摘要：
The present invention relates to an apparatus for measuring magnetic plethysmography using a time varying magnetic field and, more specifically, to an apparatus for measuring magnetic plethysmography using a time varying magnetic field comprising: an oscillator module for applying a time-varying magnetic field to a blood vessel through a coil adjacent to the blood vessel, and for generating a detection signal to which a change in inductance of the coil caused by blood flow inside the blood vessel influenced by the time-varying magnetic field is reflected and a signal processing module for generating pulse wave data by processing the detection signal. Moreover, the present invention relates to a method for measuring magnetic plethysmography using a time varying magnetic field and, more specifically, to a method for measuring magnetic plethysmography using a time varying magnetic field comprising: a step (1) for applying a time-varying magnetic field to a blood vessel through a coil adjacent to the blood vessel a step (2) for detecting a detection signal to which a change in inductance of the coil caused by blood flow inside the blood vessel influenced by the applied time-varying magnetic field is reflected and a step (3) for generating pulse wave data by processing the detection signal. The present invention has effects of applying a time-varying magnetic field to a blood vessel, generating pulse wave data by detecting a change in inductance of a coil caused by blood flow influenced by a time-varying magnetic field, correctly and conveniently measuring blood flow in an electromagnetic method using an oscillator module without an additional sensor thereby, and measuring pulse wave data and treating in a magnetic field at the same time without an additional flow measurement device in magnetic field therapy.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 상
