Pulse wave monitoring device
First Claim
1. A pulse wave monitoring device comprising:
- a pulse wave detection device configured to detect a pulse wave of a subject;
a computation unit that identifies a plurality of characteristic points of the pulse wave detected by the pulse wave detection device, calculates a plurality of characteristic parameters corresponding to the identified characteristic points and calculates an index indicative of a pulse wave reflection by performing a computation on the characteristic parameters;
a blood pressure measuring device configured to measure a blood pressure of the subject; and
a display unit that shows the calculated index and the measured blood pressure.

Abstract
A sensor is pressurized adjustably against a patient'"'"'s wrist and detects a pressurized pulse wave of a radial artery in a noninvasive manner so as to measure blood pressure on an arm band wound around the patient'"'"'s predetermined portion. A CPU calculates indices reflecting a reflecting phenomenon of a pulse wave as organism information different from the blood pressure based on the detected pulse waveform, and relates the measured blood pressure value with calculated indices so as to display them on an indicator. A doctor checks displayed contents so as to clearly understand a state of a circulatory system represented by a correlation between the patient'"'"'s blood pressure and the indices so as to be capable of obtaining information which supports a diagnosis and prescription quickly.
