  • Patent number: 10575763
    Abstract: An oximeter device has an ergonomically shaped enclosure that allows a user to comfortably grip and use the device during handheld operation. A sensor tip can be easily placed evenly on the tissue surface, so that all sources and detectors are directly on the tissue with even pressure. This allows for more consistent and accurate results. The user can easily move the device from one position to another and take numerous measurements. The user will have a wide, unobstructed view of the tissue because of the tip's small size, angle of display, and the grip and fingers are positioned away from the tip. Components housed by the enclosure are arranged to give the device a balanced weighting while in the hand. The device can be used for long periods at a time without fatigue.

  • Patent number: 10537271
    Abstract: A device includes source and detector sensors. In a specific implementation, the device has two near detectors, two far detectors, and two sources. The two near detectors are arranged closer to the two sources than the two far detectors. A light-diffusing layer covers the two near detectors. The device may be part of a medical device that is used to monitor or measure oxygen saturation levels in a tissue. In a specific implementation, light is transmitted into the tissue and received by the detectors. An attenuation coefficient is first calculated for a shallow layer of tissue. The attenuation coefficient is then used to calculate an attenuation coefficient for a deep layer of tissue.

  • Patent number: 10506989
    Abstract: A method for quantifying a glucose concentration is a method for quantifying a glucose concentration in which near-infrared light is emitted onto a living organism and a glucose concentration in a biological tissue is measured using a signal obtained by receiving diffusely reflected light or transmitted light from the biological tissue. A concentration calculation step calculates a concentration index of a glucose component by using at least a spectrum of a water component, a spectrum of a glucose component, and a spectrum of a fat component to synthesize a difference spectrum between a measurement spectrum at a time of measurement of a glucose concentration and a spectrum serving as a reference obtained previous to the measurement spectrum. A glucose concentration calculation step calculates a glucose concentration in the living organism using the calculated concentration index.
