PULSE WAVE MEASURING APPARATUS AND AUTONOMIC NERVOUS ANALYSIS SYSTEM HAVING THE SAME
First Claim
1. A pulse wave measuring apparatus comprising:
- a sensor unit;
a light emitting unit provided on the sensor unit and configured to emit light to a target region that is a body part of a subject;
a light receiving unit provided on the sensor unit and configured to receive the light reflected from the target region to generate a received light signal that represents a change in blood flow in the target region;
a measuring unit having a principal surface, holding the sensor unit on the principal surface and configured to measure a pulse wave of the subject, from the change in blood flow in the target region;
a belt being expandable and configured to wrap around the target region to hold the measuring unit, with the principle surface facing the target region; and
an elastic member arranged on the principle surface to surround the sensor unit.
