  • Publication number: 20210219853
    Abstract: A belt providing improved durability and a blood pressure measurement device. A second belt of a belt of a blood pressure measurement device includes a second belt body constituted in a band-like shape using a resin material and including a plurality of small holes formed along a longitudinal direction, and a second insert being disposed in the second belt body and including a plurality of holes with a plurality of the small holes disposed on an inner side of the respective holes, a cross section of a portion of the second insert, which is between two adjacent holes and orthogonal to a width direction of the second belt body, being constituted like a trapezoid with a short side being disposed on a living body side, and the second insert being formed of a material having a higher tensile strength than the resin material constituting the second belt body.

  • Patent number: 10856649
    Abstract: A toothbrush includes a main body that includes a head portion with a bristle raising surface on which bristles are provided in a standing manner, a grip portion, and a neck portion. A light emission portion that emits light through a specific region of the bristle raising surface toward a tooth surface and a light reception portion that receives radiated light from the tooth surface resulting from the light, through the specific region, are provided inside of the main body. It is determined whether or not there is dental plaque on the tooth surface based on the output of the light reception portion. A light reception and condensing portion that condenses the radiated light from the tooth surface toward the light reception surface of the light reception portion is arranged in the housing portion forming the specific region.

  • Patent number: 10835029
    Abstract: A toothbrush including a main body having a shape which is narrow and long in one direction; and a brush member which has a cylindrical shape and which is mounted to an end section in the lengthwise direction of the main body. The brush member includes: a head part which has a raised surface, on which bristles are erected, along the lengthwise direction of the main body to which the brush member is mounted; and a neck part which is mounted by engaging with the periphery of the end section of the main body. In the head part, a back surface on the opposite side of the raised surface is opened, and the neck part is provided with a detachment prevention mechanism that prevents the end of the main body to which the brush member is mounted from detaching.
