Abstract

SOPORTE DE TEST PARA DETERMINACION ANALITICA DE UN COMPONENTE DE UNA PRUEBA LIQUIDA, ESPECIALMENTE PARA LA DIAGNOSIS DE ENFERMEDADES. SOBRE UNA CAPA BASE (2) SE ENCUENTRA UNA ZONA DE FUNCION DE PRUEBA (4) Y UNA ZONA DE VALORACION (6), QUE SE CONECTAN UNA CON OTRA POR UN RECORRIDO DE TRANSPORTE DE LIQUIDO. EN LA ZONA DE VALORACION (6) ESTA COLOCADA UNA CAPA DE FORMACION DE COLOR (11) QUE TIENE LUGAR UNA VARIACION MANIFIESTA OPTICA CARACTERISTICA PARA EL ANALISIS. PARA PODER CONTROLAR EN UN SOPORTE DE TEST DE TAL CALASE CON TRANSPORTE LONGITUDINAL EL RIEGO SEGUN LA ORDEN DE LA CAPA DE TEST Y CON ELLO MEJORAR LA DOSIFICACION DE LA PRUEBA, ESTA COLOCADA EN LA ZONA DE VALORACION (6) SOBRE LA CAPA DE FORMACION DE COLOR (11) UNA CAPA DE CUBIERTA (7) ABSORBENTE QUE EN EL ESTADO DE SALIDA DEL SOPORTE DE TEST HACE INVISIBLE EL COLOR DE LA CAPA DE FORMACION DE COLOR (11). LA CAPA DE CUBIERTA (7) ESTA EN CONTACTO FLUIDO CON EL RECORRIDO DE TRANSPORTE DE LIQUIDO. LA CAPA DE CUBIERTA (7) Y LA CAPA DE FORMACION DE COLOR (11) ESTAN FORMADAS DE TAL MODO QUE LOS COLORES DEL REACTIVO DE FORMACION DE COLOR SON VISIBLES CUANDO AMBAS CAPAS SE MOJAN POR EL LIQUIDO DE PRUEBA.
