Blood pressure measuring device, blood pressure measuring method, blood pressure measuring program and method for generating a classifier

Abstract

For suppressing noise generation during control switching and capturing a clean pressure pulse wave even at low pressure. A blood pressure measuring device including: a cuff to be wrapped around a measurement target site; a pressure sensing unit that detects cuff pressure within the cuff; a pressure control unit that controls the cuff pressure; a blood pressure calculation unit that performs blood pressure calculation processing, calculating a patient's blood pressure based on the detected cuff pressure; and a wrapping strength determination unit that performs wrapping strength determination processing, determining the wrapping strength of the cuff around the measurement target site.The pressure control unit performs a constant rate pressure application control, so that the cuff pressure increase occurs at a constant rate throughout the entire blood pressure calculation processing performed after the start of the cuff pressure application and at the end of the blood pressure calculation processing.
