Abstract: A blood pressure measurement device includes an outer case; a base; a pump provided on a surface of the base such that the pump is shifted from a center of the outer case and located on one side as viewed in a circumferential direction of a living body; a first pressure sensor and a second pressure sensor that are provided such that the first pressure sensor and the second pressure sensor are arranged side by side in the circumferential direction and located on one side as viewed in a direction orthogonal to the circumferential direction; and a first on-off valve and a second on-off valve that are provided such that the first on-off valve and the second on-off valve are arranged side by side in the circumferential direction with reference to the first pressure sensor and the second pressure sensor.

Abstract: A blood pressure measurement device includes a bag-like pressing cuff wound around a measurement target site of a living body; a back plate arranged on the living body side of the pressing cuff; a bag-like sensing cuff arranged on the living body side of the back plate; a supply device configured to supply a fluid into the cuffs; first guides arranged on the living body side of the pressing cuff and configured to form wrinkles in a direction intersecting the winding direction; and second guides arranged on the living body side of the sensing cuff and configured to form wrinkles in the direction intersecting the winding direction.

Abstract: A sphygmomanometer according to the present disclosure includes a main body that is mounted with a pump and is to be disposed on a dorsal surface of a wrist and a cuff that is to be attached around the wrist. The cuff extends along a circumferential direction of the wrist from an ulnar side end portion of the main body to a palmar surface and is set to a length covering an ulnar artery or a length covering a radial artery beyond the ulnar artery of a wrist having a preset maximum wrist circumference. A fluid is supplied from the pump to the cuff to press the wrist. A blood pressure is calculated based on a pressure of the fluid contained in the cuff.

Abstract: The light-emitting device includes a light-emitting element, a light-transmissive member, a light-blocking layer and a light-reflective member. The light-transmissive member has a first main surface and a second main surface opposite to each other. The first main surface and the second main surface are smaller than a light-emitting surface of the light-emitting element. The first main surface faces the light-emitting surface of the light-emitting element. The light-blocking layer is disposed on the light-emitting surface to cover a region between an outer edge of the light-emitting surface and an outer edge of the first main surface. The light-reflective member covers at least a portion of lateral surfaces of the light-emitting element and at least a portion of the light-transmissive member. The light-blocking layer extends inward of the outer edge of the first main surface.

Abstract: A light-emitting device includes a light-emitting element, a wavelength conversion member arranged on the light-emitting element, a light-reflective member and a light-distributing member. The light-reflective member covers lateral surfaces of the light-emitting element and the wavelength conversion member while an upper surface of the wavelength conversion member being exposed from the light-reflective member. The light-distributing member has a plate shape with an upper surface and a lower surface. An inner wall of the light-distributing member defines a through-hole disposed above the wavelength conversion member and extending between the upper surface and the lower surface. The inner wall is inclined from an upper edge of the through-hole defined by the upper surface toward a lower edge of the through-hole defined by the lower surface so that an opening defined by the lower edge is larger than an opening defined by the upper edge.
