Title:
AUTOMATIC BLOOD PRESSURE MEASURING DEVICE EQUIPPED WITH BLOOD PRESSURE ESTIMATING FUNCTION
Document Type and Number:
Japanese Patent JP3501492
Kind Code:
B2
Abstract:
PURPOSE: To estimate the blood pressure of an organism prior to the measurement of the blood pressure during the slow pressure lowering period of a cuff.
CONSTITUTION: The shape of the pulse wave and the relationship between the pressing pressure PC of a cuff 11 at the time of the occurrence of the pulse wave and the blood pressure of an organism are determined by a relationship determining means 56, while the blood pressure is estimated by a blood pressure estimating means 60 on the basis of the shape of the actual pluse wave detected by a pulse-wave shape detecting means 58 during the rapid pressure rising period of the cuff 10 from the above relationship and the pressing pressure PC of the cuff 10 at the time of the occurrence of the pulse wave. Thus, the blood pressure of the organism during the rapid pressure rising period of the cuff prior to the slow pressure lowering period thereof is estimated, and an approximate blood pressure of the organism can be quickly obtained.
