Abstract

La presente invención se refiere a sistemas transdérmicos no invasivos y métodos para extracción de analitos de un fluido biológico dentro o debajo de la piel, tal como fluido intersticial, y detección del analito. Más especialmente, la presente invención se refiere a sistemas transdérmicos no invasivos que comprenden un parche no invasivo y un reflectómetro. Los parches transdérmicos no invasivos están compuestos por un componente de química húmeda y un componente de química seca. El componente de química húmeda es un medio de transferencia líquida en la forma de una capa de gel para la extracción y transferencia puenteada de líquidos del analito de interés del fluido biológico dentro o debajo de la piel al componente de química seca. El componente de química seca es una membrana supersensible y acondicionada que lleva un sistema reactivo para interactuar con el analito de interés para generar una molécula indicadora, por ej: cambio de color, para confirmar la detección del analito, y métodos para el uso de lo mismo. La molécula indicadora puede ser observada visualmente por el usuario u observada por un componente de interpretación electrónica, tal como un espectrofotómetro de reflectancia para detección. Una analito de interés en particular, que puede ser detectado de manera exacta, confiable y cuantitativa de acuerdo con la presente invención es glucosa. Los sistemas transdérmicos no invasivos de la presente invención son económicos e indicados para uso conveniente por parte de personal no médico. ...<EMI FILE="00018126_1" ID="1" IMF=JPEG > SOLICITUDES DE PATENTES DE INVENCIÓNORDENADAS PUBLICAR EN ENERO DE 2003 IMPORTANTESOLICITUDES DE PATENTE DE INVENCIÓN: a partir de la fecha de publicación de esta gaceta el solicitante cuenta con un plazo de seis (6) meses para pedir que se practique el examen de patentabilidad de la solicitud, anexando el recibo de pago de la tasa correspondiente a tal fin.
