Title:
BLOOD PRESSURE MEASUREMENT DEVICE, BLOOD PRESSURE MEASUREMENT METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2016/189840
Kind Code:
A1
Abstract:
Provided is a blood pressure measurement device capable of accurately estimating blood pressure. A blood pressure measurement device 5007 comprises: a first blood pressure estimation unit 5004 that estimates blood pressure on the basis of a first pressure signal indicating the internal pressure of a cuff 401 during a first period and Korotkoff sounds in the first period or on the basis of the first pressure signal in the first period and a first pulse wave signal indicating the pulse wave in the first period; a pulse wave calculation device 5003 that calculates multiple times when the first pulse wave signal fulfills a prescribed condition, a third period indicating the differences in the times, and the pressure of the first pressure signal in the third period, and calculates first pulse wave data in which the third period is associated with the pressure; a blood pressure data generation unit 5005 that generates blood pressure data in which the calculated first pulse wave data is associated with the estimated blood pressure; and a second blood pressure estimation unit 5006 that specifies, in the blood pressure data, the first pulse wave data that is similar to or the same as second pulse wave data calculated on the basis of a second pressure signal indicating the internal pressure of the cuff in a second period and a second pulse wave signal indicating the pulse wave in the second period, and estimates the blood pressure associated with the specified first pulse wave data to be the blood pressure in the second period.
