摘要
An apparatus (8) for iteratively estimating an intra-arterial blood-pressure value of a living subject, including a first information obtaining device (74) which non-invasively and iteratively obtains information relating to propagation of a pulse wave through an arterial vessel of the subject, a second information obtaining device (76) which non-invasively and iteratively obtains information relating to heartbeat of the subject and/or information relating to area of a heartbeat-synchronous pulse of a volumetric pulse wave obtained from a peripheral body portion of the subject, and an estimating device (82) including a neural network which learns sets of information each set of which includes a blood-pressure value measured using a cuff, pulse-wave-propagation-relating information obtained when the blood-pressure value is measured using the cuff, and heartbeat-relating information and/or pulse-wave-area-relating information obtained when the blood-pressure value is measured using the cuff, the neural network iteratively estimating an intra-arterial blood-pressure value of the subject, based on each piece of pulse-wave-propagation-relating information iteratively obtained by the first information obtaining device, and each piece of heartbeat-relating information and/or each piece of pulse-wave-area-relating information which are or is iteratively obtained by the second information obtaining device.
