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. |
