PULSE WAVE MEASURING APPARATUS USING LASER SPECKLE IMAGE AND PULSE WAVE MEASURING METHOD USING THIS APPARATUS

摘要

PURPOSE: A device and a method for measuring a pulse wave are provided to obtain the minimum blood pressure, the maximum blood pressure, an average blood pressure, and a pulse wave form of a subject by obtaining a laser speckle image in real time. CONSTITUTION: A pressing unit(200) fixes a wrist of a subject and presses a part of the wrist. A speckle image obtaining unit(100) obtains speckle image information by emitting one or more laser beams to the fixed wrist of a subject through a laser speckle interferometry. A central process unit obtains and reveals pulse wave form by receiving the speckle image information obtained by the speckle image obtaining unit in real time.
