Abstract: A blood pressure measurement device includes a curler that curves to follow a circumferential direction of a site of a living body where the curler is attached, and a cuff. The cuff includes a plurality of bag-like structures layered on one another, each of the plurality of bag-like structures being elongated in one direction, formed by welding two sheet members formed of a resin material, and configured to be inflated with a fluid, and a joined portion provided on at least a portion of an edge portion of the bag-like structure disposed facing the curler, the joined portion being formed by a portion of the sheet members constituting the bag-like structure disposed facing the curler and joined to an outer circumferential surface side of the curler.

Abstract: A blood pressure measurement device enabling an increase in joining strength between a cuff and a junction target preventing an increase in size of the blood pressure measurement device. The device includes a case including an outer case having a tubular shape, a curler curving in such a manner as to follow along a circumferential direction of a portion of the wrist where the blood pressure measurement device is attached, the curler including a first facing portion aligned at one end of the outer case in a thickness direction, and a back-side cuff formed of two sheets formed of a resin material, the back-side cuff being configured to be inflated with a fluid, one of the sheet members that is disposed on the curler side including a second facing portion facing the first facing portion, and the second facing portion being larger than other portions of the back-side cuff.

Abstract: A belt includes; a first belt portion including a cover layer formed of a resin material and a first insert layer disposed within the cover layer and formed of a high-tensile material having a tensile strength higher than that of the resin material, the first belt portion having a bent shape along a circumferential direction of a living body; and a second belt portion configured to be connected to the first belt portion.

Abstract: A blood pressure measurement device includes: a case including an outer case, a base housed in the outer case, and a back cover that covers an opening of the outer case; a movable portion arranged in a gap between the outer case, the base and the back cover, and including a bag-shaped cuff that inflates when a fluid is supplied to an internal space; and a seal member that is formed of a gel body having a lower elastic modulus than that of the cuff, and that is provided in the gap to seal the gap.
