PULSE WAVE INFORMATION MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a pulse wave information measuring device of high detection sensitivity and data reliability by improving adhesion performance between a living body surface and a transparent plate.

SOLUTION: In this pulse wave measuring device of an arm-installed type, the transparent plate 34 is disposed on the surface of an LED 31 and a photo-transistor 32 in a sensor unit 30. An outside surface 341 of the transparent plate 34 to which a finger is pressed is at a position protruded from a reference surface when an outside surface 361 of a sensor frame 36 surrounding the transparent plate 34 is set as the reference surface. Around the transparent plate 34, two human body grounding terminals 38 are disposed to get in contact with the surface of the finger when the finger is tightly applied to the transparent plate 34. The human body grounding terminal 38 is protruded from the reference surface. An outside surface 381 of the human body grounding terminal 38 is at a lower position than the outside surface 341 of the transparent plate 34.
