Abstract
UN DISPOSITIVO ANALITICO (10) PARA LA DETERMINACION CUALITATIVA Y/O CUANTITATIVA DE UN ANALITICO EN UNA MUESTRA DE ENSAYO LIQUIDO COMPRENDE UNA BASE (12) PORTADORA DE UN ELEMENTO POROSO (16) QUE TIENE UN SUSTANCIA REACTIVA AL ANALITICO EN EL MISMO, LA SUSTANCIA PUEDE EXPERIMENTAR UN RESPUESTA DETECTABLE ANTE LA PRESENCIA Y/O CONCENTRACION DEL ANALITICO EN LA MUESTRA DE ENSAYO. UNA TAPA (18) INTEGRAL CON LA BASE (12) SE PROPORCIONA CON UNA DEPOSITO DE REACCION (28) FORMADA EN LA MISMA PARA ALMACENAR UNA COMPONENTE DE REACCION DESHIDRATADO (34) Y PARA RECIBIR LA MUESTRA DE ENSAYO LIQUIDO PARA FORMAR (CON EL COMPONENTE DE REACCION) UNA MEZCLA DE REACCION LIQUIDA EN LA MISMA. EL DEPOSITO DE LA REACCION TIENE UN PASO INTERMEDIO (30) QUE GENERALMENTE ESTA SEPARADO DEL ELEMENTO POROSO (16) Y CERRADO EFICAZMENTE PARA TRANSFERIR A TRAVES DE LA MEZCLA DE REACCION, PERO QUE SE DESPLAZA HACIA EL ELEMENTO POROSO EFICAZMENTE PARA ABRIR EL PASO INTERMEDIO PARA PERMITIR EL FLUJO A TRAVES DE LA MEZCLA DEREACCION AL ELEMENTO POROSO (16). LA SUSTANCIA REACTIVA DEL ANALITICO EN EL ELEMENTO POROSO EXPERIMENTARA UNA REACCION DETECTABLE PARA CUALQUIER ANALITICO PRESENTE EN LA MEZCLA DE REACCION LIQUIDA. LA BASE SE PUEDE PROPORCIONAR CON UN PUERTO DE VISUALIZACION ADECUADO (54) PARA PERMITIR LA MONITOREO DE LA REACCION DETECTABLE GENERADA EN EL ELEMENTO POROSO.
