Abstract
A pulse diagnosis device which can detect the pulsation signal of a radial artery using an optical sensor comprising: a sensor module for sensing the pulsation signal by closely adhering thereto a prescribed body part; and a system control portion for operating the sensor module, and processing the optical signal sensed from the sensor module, wherein the sensor module comprises: an optical waveguide-type sensor which is placed on the bottom surface of the sensor module, and lets the optical signal to pass therethrough and detects the change in optical characteristics due to the change in the pressure; a light-source module which is connected on one side surface of the optical waveguide-type sensor, and inputs the optical signal into the optical waveguide-type sensor; and an optical detector module which is connected on one side surface of the optical waveguide-type sensor, and detects the optical signal delivered from the optical waveguide-type sensor.
