High blood pressure measurement accuracy can be achieved with a blood pressure monitor employing a double cuff structure. A blood pressure monitor of the present invention includes a pressing member that includes a pressure cuff having a bag shape capable of containing fluid and generates a pressing force toward a measurement site of a subject when the pressing member is wound around the measurement site and the pressure cuff is inflated, and a controller that controls an operation of the adjuster such that the fluid is contained in the sensing cuff in an amount corresponding to biometric information about the subject and the pressure cuff is inflated or inflated and deflated in this state when performing a blood pressure measurement, and calculates a blood pressure value of the subject based on an output from the pressure sensor.

Blood pressure monitor, blood pressure measurement apparatus and blood pressure measurement method

A bag-shaped structure for a blood pressure monitor cuff that is wrapped around a living body and is inflated by supplying a fluid to an internal space to apply a pressure to the living body, includes an inner wall portion that is positioned on the living body's side, has a Shore A hardness of 15 to 75, and has a thickness of 0.10 mm to 0.40 mm, an outer wall portion that faces the inner wall portion, and a pair of side wall portions that are provided in a manner to be continuous with the inner wall portion and the outer wall portion, have a Shore A hardness equal to the Shore A hardness of the inner wall portion, and have a thickness that falls within a range of 0.15 mm to 0.60 mm and is equal to or greater than a thickness of the inner wall portion.

Bag-shaped structure, cuff for blood pressure monitor, and blood pressure monitor

A bag-shaped structure excellent in vascular compressibility and creep resistance, and capable of reducing the processing cost, a blood pressure monitor cuff, and a blood pressure monitor is provided. A bag-shaped structure includes a first sheet member including a layer formed of a thermoplastic elastomer; and a second sheet member including a plurality of layers formed of a plurality of types of thermoplastic elastomers having different levels of hardness, wherein the second sheet member is joined with the first sheet member, and a layer, that is included in the plurality of layers of the second sheet member and that is in contact with a living body, has a Shore A hardness higher than a Shore A hardness of at least one of the other layers of the second sheet member.

Bag-shaped structure, blood pressure monitor cuff, and blood pressure monitor

A bag-shaped structure excellent in both creep resistance and flexibility is provided. Provided is a bag-shaped structure () including a layer () made of a thermoplastic elastomer foam. Also provided are a cuff for a blood pressure monitor and a blood pressure monitor each including the bag-shaped structure ().

Bag-shaped structure, cuff, and blood pressure monitor

To provide a bag-shaped structure that can suppress expansion of the side wall portion and improve the vascular compression property. A bag-shaped structure used in a cuff for a blood pressure monitor configured to be wrapped around a living body, inflate when a fluid is supplied to an internal space, and compress the living body includes: an inner wall portion provided on a living body side; an outer wall portion facing the inner wall portion; and a pair of side wall portions continuous with the inner wall portion and the outer wall portion and including a bent portion bent toward the internal space; and a reinforcing member provided on each of the pair of side wall portions, having a higher hardness than the side wall portion, and having shape followability in a direction of wrapping around the living body.
