49. A method of obtaining a blood pressure measurement, comprising:
-
stretching a resilient stretch fabric sleeve to fit on a limb of a patient so that at least a major portion of the sleeve body elastically expands to snugly and substantially conformably reside around the limb as a first closed member that stretches to compress the selected limb portion;
thenwrapping a blood pressure cuff over the sleeve and attaching the cuff theretogether so that the blood pressure cuff surrounds the sleeve and defines a second closed member over the sleeve; inflating the blood pressure cuff to a pressure sufficient to restrict blood flow in a selected artery proximate the sleeve and blood pressure cuff while elastically compressing the sleeve under the blood pressure cuff during the inflating; releasing the inflation pressure in the blood pressure cuff; and detecting a blood pressure measurement. - View Dependent Claims (50)
