Abstract
A method and apparatus for winding a cuff having an inflatable chamber around a body portion of a living subject, in measuring a blood pressure of the subject, the method including the steps of positioning the cuff and the body portion of the subject relative to each other such that the cuff surrounds the body portion, supplying a predetermined amount of gas into the chamber of the cuff to hold the gas in the chamber, and fastening the cuff after increasing a tension of the cuff till a gas pressure in the chamber of the cuff surrounding the body portion reaches a reference value. A cuff winding apparatus includes a gas supplying device which supplies a predetermined amount of gas into the chamber of the cuff to hold the gas in the chamber, a pressure sensor which detects a gas pressure in the chamber of the cuff, a judging device for judging whether the pressure of the chamber detected by the pressure sensor has reached a reference value, and a driving device which increases a tension of the cuff to reduce a diameter of the cuff surrounding the body portion of the subject, the driving device holding the diameter of the cuff when the judging device makes a positive judgment.
