Blood pressure measurement device

Abstract

A blood pressure measurement device (1) comprises a device body (3); a collar (5) that is affixed to the device body (3), curves along the circumferential direction around a wrist (200) of a body, hasone end and another end formed separate from one another, and contacts at least the area between the dorsal side and the palmar side of the wrist (200); a belt (4) that is provided on the device body(3), covers the outer surface of the collar (5), and is fastened to the wrist (200); a sensing cuff (73) that is disposed in a region in which an artery (210) of the wrist (200) is present; a back plate (72) that is provided on the collar (5)-facing side of the sensing cuff (73), and extends in the circumferential direction of the wrist (200); an elastically deformable rubber plate (76) that is provided on the collar (5)-facing side of the back plate (72); a compression cuff (71) that is provided between the collar (5) and the rubber plate (76), and compresses the sensing cuff (73); and a cuff (74) that is provided on the body-facing side of the collar (5), and is disposed on the dorsal side of the wrist (200).

Description

technical field [0001] The present invention relates to a blood pressure measuring device for measuring blood pressure. Background technique [0002] In recent years, blood pressure measuring devices for measuring blood pressure have been used not only in medical equipment but also as devices for checking health status at home. A blood pressure measurement device measures blood pressure by, for example, wrapping a sensor cuff around the upper arm or wrist of a living body, expanding and contracting the sensor cuff, and detecting the pressure of the sensor cuff with a pressure sensor, thereby detecting the vibration of the artery wall . [0003] As such a blood pressure measurement device, for example, a so-called all-in-one device in which a cuff and a device body that supplies a fluid to the cuff are integrally configured is known. Recently, such an integrated blood pressure measuring device is required to be miniaturized as a wearable device worn on the wrist. Therefore...

AI Technical Summary

Problems solved by technology

In particular, the smaller the cuff becomes due to the miniaturization of blood pressure measuring devices, the less accurate the blood pressure measurement may be

[0005] In addition, there is a problem that blood pressure cannot be accurately measured not only in wearable devices, but also in biological information measuring devices that measure pulse, for example, and pulse cannot be accurately measured.
