Abstract
A device for the non-invasive measurement of the concentration of a specific analyte, particularly glucose, in arterial blood flowing in a patient's body part, which device comprises a solid first portion having a surface profile adapted to be held against the selected body part, a source of near infrared radiation mounted in a second portion associated with said first portion such that near infrared radiation is transmitted through or reflected from said body part, a third portion containing a detector and filters to receive radiation transmitted through or reflected from said body part, to select signals generated by the pulsatile component of the absorption spectrum and to provide a ratio representative of the desired concentration. A method for the determination of glucose concentration in arterial blood is also disclosed.
