Abstract: Provided are a blood pressure estimation device, and the like, the device being capable of accurately estimating blood pressure. The blood pressure estimation device includes a blood pressure estimation unit which estimates a blood pressure on the basis of a pressure in a specific time period and differences between a plurality of pulse wave signals measured in the specific time period due to the 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.

Abstract: Disclosed are a blood pressure device, etc., that is capable of highly accurate of blood pressure. The blood pressure device (101) has a blood pressure 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.
