Problems solved by technology

However, when mounting in this way, moderate fastening force cannot be achieved, and it is difficult to measure the pulse wave with high precision.
[0020] In addition, in the pulse wave measuring devices disclosed in the above-mentioned Patent Documents 2 to 4, even if the sensor unit can be mounted at an appropriate position, it is difficult to wind the fastening tape with an appropriate fastening force, and it cannot be tightened properly. Force loads the sensor unit against the living body

Abstract

A pulse wave measuring apparatus is disclosed, in which a sensor unit can be fixed easily under an appropriate pressure at an appropriate position on a living organism. With the living organism fixed by a living organism fixing device, a pressure sensitive portion arranged on the sensor unit is pressed against the living organism thereby to measure the pulse wave. The living organism fixing device includes a fixing stand for fixing the living organism in position, and fastening bands for connecting the fixing stand and the sensor unit and fastening the living organism fixedly to the fixing stand while at the same time activating by pressing the sensor unit against the living organism. The fastening bands include a first band portion with one end mounted on the sensor unit and the other end mounted on the fixing stand and a second band portion with one end mounted on the sensor unit and the other end removably mounted on the fixing stand. The fixing stand has a constant force spring for pulling the other end of the first band portion with a constant force.

Description

technical field [0001] The present invention relates to a compression-type pulse wave measurement device for measuring a pulse wave by pressing a pressure-sensitive portion onto a living body, and more specifically, to a compression-type pulse wave measurement device equipped with a fixing table for fixing the posture of the living body. Background technique [0002] In general, there is known a compression-type pressure measurement device that measures the contact pressure with the object to be measured by pressing against the object to be measured. As a device to which this compression type pressure measuring device is applied, there is a pulse wave measuring device. A pulse wave measurement device is a device that presses a substrate having a pressure sensitive device against a body surface to measure a pulse wave generated in an artery located relatively shallow from the skin. Using such a pulse wave measuring device to measure the pulse wave of the subject is very impo...
