Abstract: A blood pressure measurement bladder (50) has a predetermined amount of air introduced and sealed therein. A CPU (30) measures in advance the P-V property. The blood pressure measurement bladder (50) is wrapped around a measurement site. By exerting pressure from the outer side to the blood pressure measurement bladder (50), the internal pressure in the blood pressure measurement bladder (50) is increased to exert pressure on the blood vessel. During this process, the cuff pressure in the blood pressure measurement bladder (50) generated by volumetric change of the blood vessel by changing the pressure exerted from the outer side to the blood pressure measurement bladder (50), and the pressure pulse wave data are detected. By adding the cuff compliance property obtained by the P-V property that was measured in advance to the detected data as a correction value of the pressure pulse wave, blood pressure is calculated.

Abstract: In wrapping a blood pressure measurement cuff enclosing therein a bladder, which is inflated when supplied with air, around a region for measurement, first, a predetermined amount of air is supplied to the bladder and then enclosed therein. Then, the blood pressure measurement cuff is wrapped around the region for measurement of a subject for the purpose of measuring his/her blood pressure. During this wrapping process, relative variations in the pressure in the bladder are sequentially detected. The time period in which the detection results indicate that the variation has not reached a predetermined threshold value, the wrapping proceeds. When the detection results indicate that the variation has reached the predetermined threshold value, the wrapping is terminated.
