Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0024] figure 1 It is a schematic diagram showing a schematic configuration of a biological information measurement device 100 according to an embodiment of the present invention.

[0025] The biological information measurement device 100 includes: a housing 80 ; an air bladder 70 supported by the housing 80 ; a rotational drive unit 60 fixed to the air bladder 70 ; and a pressure pulse wave sensor 10 rotatably supported by the rotational drive unit 60 . The biological information measurement device 100 is worn on the wrist of the person to be measured using a belt (not shown).

[0026] The air bag 70 constitutes a pressing member that presses the rotation drive unit 60 and the pressure pulse wave sensor 10 against the body surface of the wrist. The internal pressure of the air bag 70 is adjusted by a pump (not shown) built in the case 80 . The pump is controlled by ...

Abstract

Provided are: a pressure pulse wave sensor which is capable of ensuring sufficient durability for being attached for long periods of time, and which is capable of curbing production costs; and a biological information measurement device provided with said pressure pulse wave sensor. This pressure pulse wave sensor (10) is provided with: a sensor chip (22) provided with pressure detection elements(24); a substrate (50) to which the sensor chip (22) is fixed; and a protective cover (40) for protecting the substrate (50) and the sensor chip (22). The outer circumferential surface of the protective cover (40) is provided with a top surface (41) which is disposed above the pressure detection elements (24) in a direction (Z) orthogonal to a detection surface (26) of the sensor chip (22), and which is parallel to the detection surface (26). The protective cover (40) has, formed therein, an opening (42) which passes therethrough from a detection-surface (26) facing position in the top surface(41), towards the detection-surface (26) side. The space between the opening (42) and the detection surface (26) is filled with a filler (55).

Description

technical field [0001] The invention relates to a pressure pulse wave sensor, a pulse wave detection device and a biological information measuring device. Background technique [0002] There is known a biological information measuring device capable of measuring biological information such as pulse or blood pressure by using the information detected by the pressure sensor in a state where the pressure sensor is in direct contact with the body part through which arteries such as the radial artery of the wrist pass (for example, refer to Patent No. Literature 1). [0003] A pressure sensor mounted on a biological information measuring device described in Patent Document 1 includes: a circuit board; a spacer provided on the circuit board; a sensor chip provided on the spacer; a housing for accommodating the circuit board; A protective plate that protects the circuit board. An opening is provided on the protective plate, from which the sensor chip protrudes. [0004] prior ar...
