Abstract: A low volume or narrower blood pressure cuff compared to commercial counterparts with similar medical approval accuracy is introduced. The present invention comprises an occlusion component configured to occlude the artery, and a pulse wave detection component to detect blood pressure oscillations. Blood pressure readings within medical approval accuracy are achieved by controlling and adjusting fluid amount in or fluid flowing into said pulse wave detection component.

Abstract: Disclosed are a blood pressure estimation device, etc., that is capable of highly accurate estimation of blood pressure. The blood pressure estimation device (101) has a blood pressure estimation unit (102) that: finds a specific blood pressure related to pulse wave information (2002), by browsing blood pressure information (2001) associating the pulse wave information and blood pressure related to pulse wave signals caused by blood pressure during a specific period and measured, the pulse wave information associating blood pressure during the specific period and the pulse wave signals; and estimates the blood pressure relating to the pulse wave information (2002) on the basis of the found specific blood pressure.

Abstract: Disclosed are a blood pressure estimation device and the like which make it possible to estimate blood pressure with a high degree of accuracy. A blood pressure estimation device (101) has: a pulse wave calculation unit (102) for, on the basis of a pressure signal in a specific period and a pulse wave signal (2001) measured on the basis of the pressure of the pressure signal in the specific period, calculating a plurality of times at which a pulse signal satisfies prescribed conditions, a period representing the difference between the times, and a pressure value of the pressure signal during the period, and also calculating pulse wave information associating the period and the pressure value; and a blood pressure estimation unit (103) for estimating the blood pressure of the pulse wave signal (2001) on the basis of the pulse wave information.
