Abstract

Un dispositivo (2) para medir la concentración de un analito en un fluido corporal, que comprende medios depenetración en la piel (4), teniendo dichos medios de penetración (4) una longitud suficientemente corta parapenetrar solamente en la capa cutánea de la piel sin penetrar en la capa subcutánea, siendo tal longitud inferior a 2mm, y un miembro de soporte (3a) comprendiendo dicho miembro soporte (3a) un sitio detector de analito y unmicrocanal (8) para conducir dicho fluido corporal de dicho miembro de penetración (4) a dicho sitio detector deanalito, y donde dichos medios de penetración (4) están integrados en dicho miembro soporte (3a),estando dicho dispositivo dispuesto para tomar mediciones en intervalos predeterminados, comprendiendo además dicho dispositivo medios de control de flujo (12) para influenciar el flujo de fluido a losmedios detectores (11), caracterizado porque los medios de control de flujo (12) comprenden una puerta hidrofóbica (612; 128) dispuestaen un microcanal (8) que está configurado para detener el flujo de fluido a lo largo del microcanal.
