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 () has: a pulse wave calculation unit () for, on the basis of a pressure signal in a specific period and a pulse wave signal () 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 () for estimating the blood pressure of the pulse wave signal () on the basis of the pulse wave information.

Blood pressure measurement device, blood pressure measurement method, and non-transitory recording medium

Disclosed are a blood pressure device, etc., that is capable of highly accurate of blood pressure. The blood pressure device () has a blood pressure unit () that: finds a specific blood pressure related to pulse wave information (), by browsing blood pressure information () 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 () on the basis of the found specific blood pressure.

In measurement requiring application of pressure to a tissue of a living body such as blood pressure measurement, noise due to vibration tends to occur. It is difficult to accurately measure a pulse wave and a blood pressure value. It is also difficult to measure blood pressure in life activities or to measure blood pressure at intervals or continuously where a tonometer is always attached. There is consequently a problem of holding a biologic information detecting apparatus. The present invention solves the problems by providing an easy-to-wear biologic information detecting apparatus for stably detecting biologic information. The biologic information detecting apparatus includes a sensor for detecting biologic information in a pair of arms connected via a spindle, and the sensor is tightly attached to a projecting part in a living body, particularly, a tragus of an auricle.

Biologic information detecting apparatus

In measurement requiring application of pressure to a tissue of a living body such as blood pressure measurement, noise due to vibration tends to occur. It is therefore difficult to accurately measure a pulse wave and a blood pressure value, and there is a problem of measuring blood pressure stably. It is also difficult to measure blood pressure in daily life activities or to measure blood pressure at predetermined intervals or continuously in a state where a tonometer is always attached. There is consequently a problem of providing a method of holding a biologic information detecting apparatus. The present invention has been achieved to solve the problems and an object of the invention is to provide an easy-to-wear biologic information detecting apparatus for stably detecting biologic information. In order to achieve the above object, biologic information detecting apparatus according to the invention has a structure in which the apparatus includes a sensor for detecting biologic information in a pair of arms connected via a spindle, and the sensor is tightly attached to a projecting part in a living body, particularly, a tragus of an auricle.
