  • Patent number: 6575913
    Abstract: A cuff member for a sphygmomanometer that has a manually rotatable spindle mounted in a housing. One end of an inflatable cuff is attached to and wound spirally on the spindle. The spiral-wound portion of the cuff in use remaining at least partially inflatable but provides the effect of a constriction at a position along its length dependent on the extent of the spiral wound portion. The inflatable cuff extends through an opening in the housing. An end unit is attached to the other end of the inflatable cuff. A releasable fastening member fastens the end unit to the housing. A desired effective length of cuff is withdrawn from the housing via the opening to extend in a loop around the upper arm of a patient. A ratchet cooperates with the spindle to allow withdrawal of the cuff from the housing when the spindle is manually rotated in one direction and to restrain withdrawal of the cuff from the housing for rotation of the spindle in the opposite direction.
