OPTICAL DEVICE AND METHOD FOR NON-INVASIVE REAL-TIME TESTING OF BLOOD SUGAR LEVELS

DISPOSITIF OPTIQUE ET MÉTHODE D'ANALYSE NON INVASIVE EN TEMPS RÉEL DES TAUX DE GLYCÉMIE
Abstract:
(EN)
A device and method for non-invasive real-time testing of blood sugar levels in a diabetic patient. Specifically, this invention is directed to an optical device comprising a contact lens having a glucose-sensing optical pattern imprinted, marked, coated or otherwise disposed on or incorporated within the contact lens. The indicator pattern is further comprised of a glucose-sensing coating containing a boronic acid derivative, which reacts in the presence of glucose to create a readable pattern, which can then be correlated to a pre-determined or pre-calibrated blood glucose level. A polarized light source is one method that may be used to read the indicator pattern. The invention is also directed to methods for quantifying blood glucose levels using the inventive optical device and manufacturing methods for disposing the glucose-sensing coating onto, or incorporating it into, the contact lens material.
(FR)
La présente invention concerne un dispositif et une méthode d'analyse non invasive en temps réel des taux de glycémie chez un patient diabétique. Plus spécifiquement, l'invention concerne un dispositif optique comprenant une lentille de contact pourvue d'un motif optique pour la détection du glucose imprimé, marqué, recouvrant ou disposé d'une autre manière sur ou incorporé à la lentille de contact. Le motif d'indicateur est en outre constitué d'un revêtement pour la détection de glucose contenant un dérivé d'acide boronique, qui réagit en présence de glucose afin de créer un motif lisible, qui peut être mis en corrélation avec un taux de glycémie prédéterminé ou pré-étalonné. Une source de lumière polarisée est une méthode qui peut être utilisée pour lire le motif indicateur. L'invention concerne également des méthodes de quantification des taux de glycémie au moyen du dispositif optique de l'invention, ainsi que des procédés de fabrication permettant de disposer le revêtement de détection de glucose sur le matériau de la lentille de contact ou de l'incorporer au dit matériau.
