Title (EN) APPARATUS AND METHOD FOR NONINVASIVE GLUCOSE MEASUREMENT
(FR) APPAREIL ET PROCEDE DE MESURE NON INVASIVE DU TAUX DE GLYCEMIE
Abstract:
(EN) An apparatus and method for noninvasively measuring blood glucose concentration. The apparatus (10) disclosed uses light pulses directed onto a patient's skin and reflected back from the patient to measure blood glucose. Reflected light is passed through light filters (30) that transmit a narrow bandwidth of light within a range of wavelengths that is absorbed by glucose and then measured. Unreflected light is passed through identical light filters (40) and also measured. The two measurements are then compared and used to calculate the patient's blood glucose concentration.
(FR) L'invention se rapporte à un appareil et à un procédé permettant de mesurer de manière non invasive le taux de glycémie. Ledit appareil (10) produit des impulsions lumineuses en direction de la peau du patient, qui sont réfléchies et permettent de mesurer le taux de glycémie. Le rayonnement réfléchi traverse des filtres colorés (30) qui transmettent une faible largeur de bande de lumière, à l'intérieur d'une gamme de longueurs d'onde, qui est absorbée par le glucose puis mesurée. Le rayonnement non réfléchi traverse des filtres colorés (40) identiques et est également mesuré. On compare ensuite les deux mesures et l'on en déduit par calcul le taux de glycémie du patient.
