Problems solved by technology

In this expansion and contraction device, for example, a pressure pump, a negative pressure pump, and a switching valve for switching the connection between them and the compression cuff are included, and they are arranged on a sensor unit that is detachably installed on the living body. In the case where the sensor unit is large and heavy, it is difficult to stably attach the sensor unit to the living body
As a result, it is practically impossible to measure blood pressure with high accuracy and stability with this device

Abstract

A pulse wave measuring apparatus is disclosed which is capable of measuring the pulse wave accurately in stable fashion and which can be reduced in size and integrated for an improved convenience. The pulse wave measuring apparatus comprises a sensor unit 20 having a plurality of semiconductor pressure sensors 6, a fixing stand 30 for fixing a living organism in position, a pressure cuff 1 for pressing the semiconductor pressure sensors 6 against the living organism, and a press operation control unit 16 for controlling the press operation of the pressure cuff 1. The press operation control unit 16 is arranged in the fixing stand 30.

Description

technical field [0001] The present invention relates to a pressure-sensitive pulse wave measuring device for measuring a pulse wave by pressing a pressure-sensitive device on a living body, and more specifically, to a pushing-type pulse wave measuring device equipped with a fixing table for fixing the posture of the living body. Background technique [0002] In general, there is known a push-type pressure measuring device that measures a contact pressure with an object to be measured by pressing against the object to be measured. As a device to which this push-type pressure measuring device is applied, there is a pulse wave measuring device. The pulse wave measurement device is a device that presses a pressure-sensitive device onto the body surface to measure the pulse wave generated by an artery located relatively shallow from the skin. In such a pressure-type pulse wave measurement device, a semiconductor pressure sensor using a strain gauge and a diaphragm is used as a p...
