Blood pressure measurement device

Abstract

A blood pressure measurement device (1) is provided with: a device body (3); a collar (5) fixed to the device body (3), the collar (5) being formed so as to curve along the circumferential direction of a wrist (200) of an organism, and so that one end and the other end thereof are separated, and the collar (5) being in contact with the wrist (200) at least between the back of the hand and the palmof the hand; a belt (4) provided to the device body (3), the belt (4) covering the outer surface of the collar (5) and being mounted to the wrist (200); a sensing cuff (73) disposed in a region wherean artery (210) of the wrist (200) is present; a rubber plate (76) for elastically deforming, the rubber plate (76) being provided on a collar (5) side of the sensing cuff (73); a pressing cuff (71)for pressing the sensing cuff (73), the pressing cuff (71) being provided between the collar (5) and the rubber plate (76); and a cuff (74) provided on the organism side of the collar (5) and disposedon the back-of-the-hand 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.
