Abstract
Official abstract text for this publication.
Provided are a blood pressure estimation apparatus, a sphygmomanometer, a blood pressure estimation system, and a blood pressure estimation method which allow continuous blood pressure measurement without adding stress to a subject's body. A plurality of sensors and a controller are included. The plurality of sensors each detect a pulse wave of a subject without applying, to the subject, pressure that is greater than predetermined pressure, and the controller calculates an estimated value of subject's blood pressure continuously, based on a measured value of the subject's blood pressure acquired from a sphygmomanometer and on output of the sensors.
First claim
Opening claim text (preview).
1 . A blood pressure estimation apparatus, comprising: a plurality of sensors that each detects a pulse wave of a subject without applying, to the subject, pressure that is greater than predetermined pressure; and a controller that calculates an estimated value of subject's blood pressure continuously, based on a measured value of the subject's blood pressure acquired from a sphygmomanometer and on output of the sensors. 2 . The blood pressure estimation apparatus of claim 1 , wherein the measured value of subject's blood pressure is acquired from a cuff sphygmomanometer, and the predetermined pressure is a pressure that the cuff sphygmomanometer applies during blood pressure measurement. 3 . The blood pressure estimation apparatus of claim 1 , wherein, when the estimated value is outside a predetermined value range, the controller notifies that the estimated value is outside the predetermined value range. 4 . The blood pressure estimation apparatus of claim 1 , wherein, when the estimated value is outside a predetermined value range, the controller prompts the subject to measure blood pressure. 5 . A sphygmomanometer, comprising: a plurality of sensors that each detects a pulse wave of a subject without applying, to the subject, pressure that is greater than predetermined pressure; a blood pressure measurement unit; and a controller that calculates an estimated value of subject's blood pressure continuously, based on a measured value of the subject's blood pressure acquired from the blood pressure measurement unit and on output of the sensors. 6 . The sphygmomanometer of claim 5 , wherein the blood pressure measurement unit measures the subject's blood pressure when the estimated value is outside a predetermined value range. 7 . The sphygmomanometer of claim 5 , wherein the plurality of sensors is disposed in the blood pressure measurement unit. 8 . A blood pressure estimation system, comprising: a sphygmomanometer; and a blood pressure estimation apparatus, wherein the blood pressure estimation apparatus comprises: a plurality of sensors that each detects a pulse wave of a subject without applying, to the subject, pressure that is greater than predetermined pressure; and a controller that calculates an estimated value of subject's blood pressure continuously, based on a measured value of the subject's blood pressure acquired from the sphygmomanometer and on output of the sensors. 9 . A blood pressure estimation method, comprising: detecting a pulse wave of a subject by a plurality of sensors without applying, to the subject, pressure that is greater than predetermined pressure; calculating an estimated value of subject's blood pressure continuously, based on a measured value of the subject's blood pressure acquired from a sphygmomanometer and on output of the sensors.
