Abstract:
An apparatus for iteratively measuring a blood pressure of a living subject who is undergoing a blood-dialysis treatment, comprising:an inflatable cuff which applies a pressing force to a body portion of said subject; a blood-pressure measuring device which measures a blood pressure of said subject by changing the pressing force of the cuff applied to the body portion of said subject; a starting means for starting the blood-pressure measuring device at a predetermined period in a dialysis duration in which said subject undergoes the blood-dialysis treatment, so that the blood-pressure measuring device iteratively measures a blood pressure of said subject at the predetermined period; a period memory device which stores, for a plurality of living subjects including said subject, a plurality of sets of predetermined periods each set of which comprises respective predetermined periods for a plurality of partial durations of the dialysis duration; an identifying means for identifying said subject; and a selecting means for selecting, from the sets of predetermined periods stored in the period memory device, the set of predetermined periods for said subject, so that the starting means starts, in each of the partial durations of the dialysis duration, the blood-pressure measuring device at a corresponding one of the predetermined periods of the selected set, and the blood-pressure measuring device iteratively measures a blood pressure of said subject in said each of the partial durations of the dialysis duration at said corresponding one of the predetermined periods of the selected set.
