Abstract: A method for manufacturing a blood pressure measurement cuff includes preparing an outer cloth, preparing an inner cloth, and forming a bag-shaped portion. The bag-shaped portion has an opening on a peripheral edge of the bag-shaped portion. A curler is inserted into the bag-shaped portion through the opening, the curler being flexible and configured to curve and conform to the measurement site. An air bladder is formed by welding the opening of the bag-shaped portion such that the air bladder surrounds an inner side and an outer side of the curler thereby containing the curler. The outer cloth is attached to an outer surface on a first side of the air bladder configured to be opposite to the measurement site, and the inner cloth is attached to an outer surface on a second side of the air bladder configured to be towards the measurement site.

Abstract: A blood pressure measurement cuff is a blood pressure measurement cuff to be attached such that it wraps around a measurement site and includes: a curler that is flexible and curves so as to naturally conform to the measurement site; an air bladder containing the curler due to being wrapped around the inner side and outer side of the curler; an inner cloth attached to an outer surface on the measurement site side of the air bladder; and an outer cloth attached to an outer surface on the side opposite to the measurement site of the air bladder.

Abstract: A method for manufacturing a blood pressure information measurement apparatus includes the following steps: forming a hole in a flexible resin sheet; inserting a connecting pipe into the hole; overlaying a first end portion and a second end portion of the flexible resin sheet such that an inner side of the first end portion contacts an outer side of the second portion; welding a location at which the first end portion and the second end portion overlap to form a first welded portion, such that the flexible resin sheet forms a tube-shaped body having a first end and a second end; flattening the tube-shaped body; welding the first end and the second to form two second welded portions, such that the tube-shaped body forms a bladder having two long sides and two short sides; and welding portions of the resin sheet which overlap along a first long side to form one or more partial welded portions.

Abstract: A sphygmomanometer includes a casing including a base and a side wall surrounding the base, a circuit board provided in the casing, a piezoelectric pump located in the casing and including a nozzle of which gas is jetted out, a first lead wire and a second lead wire each having one end electrically connected to the piezoelectric pump and an other end electrically connected to the circuit board, and a first rib and a second rib each projecting from the base toward the inside of the casing. A direction in which the first rib and second rib project is substantially parallel to a direction in which the nozzle extends. The first lead wire is press-fitted between the side wall and the first rib, and the second lead wire is press-fitted between the first rib and the second rib.

Abstract: A blood pressure measurement cuff is worn on a measurement site that extends in longitudinal direction in substantial round bar shape and gradually becomes thinner from one side to another side in longitudinal direction. A band-shaped body is included which is configured to contain an air bladder between an inner cloth that is to come into contact with the measurement site and an outer cloth that opposes the inner cloth, the band-shaped body being configured to be wrapped in a circumferential direction around the measurement site. A plate member is included which is provided between the outer cloth and the air bladder in a thickness direction and in a region that corresponds to at least a portion in the circumferential direction of the band-shaped body. The thickness of the plate member gradually becomes thinner from the one side to the other side in the longitudinal direction.

Abstract: A method for manufacturing a blood pressure information measurement apparatus includes the following steps: forming a hole in a flexible resin sheet; inserting a connecting pipe into the hole; overlaying a first end portion and a second end portion of the flexible resin sheet such that an inner side of the first end portion contacts an outer side of the second portion; welding a location at which the first end portion and the second end portion overlap to form a first welded portion, such that the flexible resin sheet forms a tube-shaped body having a first end and a second end; flattening the tube-shaped body; welding the first end and the second to form two second welded portions, such that the tube-shaped body forms a bladder having two long sides and two short sides; and welding portions of the resin sheet which overlap along a first long side to form one or more partial welded portions.

A band-shaped body is included which is configured to contain an air bladder between an inner cloth that is to come into contact with the measurement site and an outer cloth that opposes the inner cloth, the band-shaped body being configured to be wrapped in a circumferential direction around the measurement site. A plate member is included which is provided between the outer cloth and the air bladder in a thickness direction and in a region that corresponds to at least a portion in the circumferential direction of the band-shaped body. The thickness of the plate member gradually becomes thinner from the one side to the other side in the longitudinal direction.

Abstract: A piezoelectric pump is provided with an actuator containing a piezoelectric element and a vibrating sheet; a first diaphragm, positioned opposite the actuator, with a first connecting hole provided therein; a pump chamber formed by the space between the actuator and the first diaphragm; and a second diaphragm positioned opposite the first diaphragm. The part of the second diaphragm opposite the first connecting hole is provided with an opposing wall portion that prevents a fluid that has been introduced into the pump chamber via the first connecting hole from flowing back towards a suction side via the first connecting hole.

Abstract: A blood pressure information measurement cuff includes a band-shaped cuff body and a fluid bladder that is connected to the cuff body and is configured to expand/contract with insertion or discharge of a fluid, the blood pressuring information measurement cuff being configured to be used while wrapped around a body being examined. The fluid bladder is formed into a rectangular bag shape by flattening a tube-shaped resin sheet and sealing the two end portions thereof that form openings. A partial welded portion, which is formed by the resin sheet being folded so as to overlap itself and welded, is formed on at least a portion of one of a pair of opposing sides that intersect the sides of the two sealed end portions and extend in a wrapping direction on the body being examined.
