Title:
PULSE WAVE SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/162000
Kind Code:
A1
Abstract:
Disclosed is a pulse wave sensor device with a light emitter (6) and a light receiver (7) provided on the surface of a peripheral wall section (2B) of a case (2). On the surface of the peripheral wall section (2B) of the case (2), a blood flow impedance reduction section (15) is provided on the right hand side of the light emitter (6) and the light receiver (7) and a fingertip positioning section (16) is provided to the left of the light emitter (6) and the light receiver (7). When a user brings the distal phalange (A) of a finger (F) into contact with the light emitter (6) and the light receiver (7), the middle phalange (B) of the finger (F) comes into contact with the contact section (15C) of the blood flow impedance reduction section (15). A difference in level arises between a section on the case (2) at the periphery of the light emitter (6) and light receiver (7) and the contact section (15C), reducing the pressure on the section of the distal phalange (A) of the finger (F) close to the first joint.
