Title:
BLOOD PRESSURE METER
Document Type and Number:
WIPO Patent Application WO/2013/061778
Kind Code:
A1
Abstract:
A blood pressure meter (100) is provided with: a cuff to be disposed around the periphery of the part of a person at which blood pressure is to be measured; an adjustment unit for adjusting pressure within the cuff by controlling a pump for supplying fluid into the cuff; a control unit for controlling the adjustment unit so that, during the measurement of blood pressure, the pressure within the cuff is increased at a constant speed according to a target pressurization speed; a pressure detection unit for detecting a cuff pressure representing the pressure within the cuff; a pulse wave detection unit (118) for detecting a pulse wave superposed on the cuff pressure; a blood pressure calculation unit for calculating blood pressure on the basis of the detected cuff pressure and of a pulse wave amplitude; and a target change unit (114) for changing in a variable manner the target pressurization speed. The blood pressure calculation unit changes the pulse wave amplitude so as to correct an error in the pulse wave amplitude caused by a change in the target pressurization speed and calculates blood pressure on the basis of the cuff pressure and the changed pulse wave amplitude.
