Abstract: A cuff for a blood pressure monitor has an air bag inflated/deflated as the air comes in/out. The air bag has an inner wall portion located on the inner side in the fitted state of the cuff and an outer wall portion located outer than the inner wall portion, and a side wall portion connecting side end portions of the inner and outer wall portions and folded inwards in the deflated state of the air bag to form a gusset at each side end portion of the air bag. A bonded portion is provided at a region of the air bag in its winding direction around the living body, for reducing expansion of the gusset formed by the side wall portion. Thus, occurrence of lateral displacement of the cuff is prevented, and a highly reliable blood pressure monitor of high performance can be obtained.

Abstract: A cuff as a living body pressing apparatus provided for a blood pressure monitor as a living body information measuring apparatus includes an air bag and a curled elastic member wound annularly around an outer side of the air bag. The air bag has an engagement portion at each side end portion in the width direction. The engagement portion is folded along the end face of the curled elastic member toward the curled elastic member, and secured to the outer peripheral surface of the curled elastic member. With this configuration, it is possible to provide a living body pressing apparatus capable of preventing occurrence of lateral displacement, and a living body information measuring apparatus provided with the living body pressing apparatus.

Abstract: A cuff for a blood pressure monitor is provided with an air bag including a first bag member located outside and a second bag member located inside in the thickness direction when fitted on a living body. The first and second bag members have first and second inflated/deflated spaces, respectively. The second bag member is formed by laying a single-layer resin sheet on the surface on the living body side of the first bag member and by melting and bonding its rim to the surface. A bonded portion of the first bag member with the resin sheet is positioned inner than each end in the width direction of the first inflated/deflated space. Thus, a cuff for a blood pressure monitor fabricated with ease and at low cost, exhibiting high pressing performance and high avascularization performance, and suitable for reduction of cuff width can be provided.

Abstract: A curled elastic member has a flexion portion allowing for local flexion. The curled elastic member is provided with an abutment piece positioned on the outer side of the flexion portion and brought into abutment with the outer surface in proximity to the flexion portion when the curled elastic member is in the shape suitable for blood pressure measurement. The flexion portion is provided with a groove on the inner circumferential side thereof with a groove bottom having the shape of an arc in cross section. A blood pressure monitor cuff and a blood pressure monitor are provided with the curled elastic member formed to be foldable without losing the essentially required characteristics.

Abstract: An air bag being inflated and deflated as air comes in and out is included. The air bag is formed of a flexible sheet material. The air bag has at least an inner circumferential sheet positioned inside when a blood pressure monitor cuff is wrapped around a living body, and an outer circumferential sheet positioned on the outer circumferential side of the inner circumferential sheet. The sheet material forming the air bag has a thickness of 0.15 mm or less. Therefore, big deep wrinkles appearing on the inner surface of the fluid bag fitted on a living body can be reduced, which may otherwise give an adverse effect on blood pressure measurement.

Abstract: A cuff for a blood pressure monitor includes an air bag, a curled elastic member wound annularly and changeable in size in a radial direction, and a bag-shaped cover member containing the air bag and the curled elastic member. The bag-shaped cover member is formed by stacking an outer cover and an inner cover and connecting their rims together. The inner cover has a folded portion formed by folding back its end portion in the width direction. The folded portion is located between the end portion in the width direction of the outer cover and the end portion in the width direction of the curled elastic member. Thus, a cuff for a blood pressure monitor easy to manufacture, suitable for reduction of cuff width, excellent in handling property when fitting, and suppressing curling and fraying of the bag-shaped cover member can be obtained.
