  • System or method for assessing a subject's peripheral blood circulation
    Patent number: 9730590
    Abstract: A system for assessing blood circulation in a subject's limb, including detection means for detecting a signal dependent upon the arterial blood volume in a limb of the subject when the subject is in a first posture and also when the subject is in a second posture, different to the first posture; and processing means for calculating a quantitative indicator that is dependent upon the ratio of the signal for the first posture to the signal for the second posture.

  • Assessing a Subject's Circulatory System
    Publication number: 20130245394
    Abstract: An apparatus comprising: an input interface configured to provide signals from at least two sensors for at least two postures including: signals, dependent upon blood presence, from a first sensor when a subject is in a first posture; signals, dependent upon blood presence, from the first sensor when the subject is in a second posture; signals, dependent upon blood presence, from a second sensor when the subject is in the first posture; and signals, dependent upon blood presence. from the second sensor when the subject is in the second posture; and processing circuitry configured to determine and output a metric by combining, according to pre-defined calibration data the provided signals.
