1. A blood pressure measurement device comprising:
a device body internally including a pump and a flow path portion configured to supply a fluid from the pump to a secondary side;
a curler including a cover portion that curves to follow a circumferential direction of a wrist from a hand back side of the wrist along one side of the wrist to a region on a hand palm-side of the wrist where at least an artery resides, and the cover portion is configured to fix the device body to the hand back side of the wrist;
a belt provided on the device body, and configured to cover an outer circumferential surface of the curler;
a pressing cuff including a first bag-like structure, a first flow path body, and a first connection portion, the first bag-like structure formed by joining two sheet members formed of a resin material, fixed to an inner circumferential surface of the hand palm-side of the wrist of the curler, and configured to be inflated by a fluid supplied from the pump, the first flow path body integrally formed with the first bag-like structure by joining the two sheet members forming the first bag-like structure facing the curler, configured to fluidly connect the pump and the first bag-like structure, and including a leading end disposed on the wrist side of the cover portion, the first connection portion provided on the leading end of the first flow path body, and configured to be inserted in the cover portion and connected to the flow path portion;
a back plate fixed on the first bag-like structure on the wrist side of the pressing cuff, and curving to follow along the circumferential direction of the wrist;
a sensing cuff including a second bag-like structure, a second flow path body, and a second connection portion, the second bag-like structure formed by joining two sheet members, fixed to a main surface of the wrist side of the back plate, and configured to be inflated by fluid supplied from the pump, the second flow path body formed integrally with the second bag-like structure by joining the two sheet members forming the second bag-like structure, configured to fluidly connect the pump and the second bag-like structure, and including a leading end disposed on the wrist side of the cover portion, and the second connection portion provided on the leading end of the second flow path body, and configured to be inserted in the cover portion and connected to the flow path portion; and
a tensile cuff including a third bag-like structure and a third connection portion, the third bag-like structure formed by joining two sheet members, fixed to an inner circumferential surface of the hand back side of the wrist of the curler, and configured to be inflated by fluid supplied from the pump, and the third connection portion provided on the third bag-like structure facing the curler, and configured to be inserted in the cover portion and connected to the flow path portion, wherein
the pressing cuff includes a first thread member at least disposed in the first flow path body,
the sensing cuff includes a second thread member at least disposed in the second flow path body, and
the second thread member includes a first thread disposed in the second flow path body and a second thread that is formed to be longer than the first thread and is disposed in the second flow path body and the second bag-like structure.
