Cuff structure and blood pressure measurement device
To provide a cuff structure capable of improving measurement accuracy of blood pressure, and a blood pressure measurement device. A cuff structure includes a sensing cuff configured in shape that is long in one direction and coming into contact with a region of a wrist where an artery is present, a pressing cuff configured in a shape that is long in one direction, provided on a side of the sensing cuff opposite from the wrist side surface, and pressing the sensing cuff against the wrist by being inflated, and a wall portion provided along at least one edge portion along a longitudinal direction of the sensing cuff and having a leading end surface on the wrist side coming into contact with the wrist.
1 . A cuff structure comprising:
a sensing cuff configured in a shape that is long in one direction, the sensing cuff configured to come into contact with a region of a wrist where an artery is present;
a pressing cuff configured in a shape that is long in one direction, the pressing cuff provided on a side of the sensing cuff opposite from a wrist side surface, the pressing cuff configured to press the sensing cuff against the wrist by being inflated; and
a wall portion provided on the sensing cuff or the pressing cuff along at least one edge portion along a longitudinal direction of the sensing cuff, the wall portion having a leading end surface configured to come into contact with the wrist, wherein
the wall portion has a height H 1 such that the wall portion protrudes beyond a height H 2 of the sensing cuff and the sensing cuff is adhered to the wrist in a state where the sensing cuff is inflated, and
wherein the height H 1 of the wall portion is configured to enable uniform presence of fluid in the sensing cuff, wherein the wall portion further includes a plurality of grooves orthogonal to the longitudinal direction and formed on the leading end surface, which are configured so that said wall portion can curve to conform to curvature of said contacted region of said wrist.
2 . A blood pressure measurement device comprising:
a device main body;
a curler provided on the device main body; and
a cuff structure provided on the curler, the cuff structure including:
a sensing cuff configured in a shape that is long in one direction, the sensing cuff configured to come into contact with a region of a wrist where an artery is present;
a pressing cuff configured in a shape that is long in one direction, the pressing cuff provided on a side of the sensing cuff opposite from a wrist side surface, the pressing cuff configured to press the sensing cuff against the wrist by being inflated; and
a wall portion provided on the sensing cuff or the pressing cuff along at least one edge portion along a longitudinal direction of the sensing cuff, the wall portion having a leading end surface configured to come into contact with the wrist, wherein
the wall portion has a height H 1 such that the wall portion protrudes beyond a height H 2 of the sensing cuff and the sensing cuff is adhered to the wrist in a state where the sensing cuff is inflated, and
wherein the height H 1 of the wall portion is configured to enable uniform presence of fluid in the sensing cuff, wherein the wall portion further includes a plurality of grooves orthogonal to the longitudinal direction and formed on the leading end surface, which are configured so that said wall portion can curve to conform to curvature of said contacted region of said wrist.
