Abstract

UN APLICADOR DE MUESTRAS PARA UTILIZAR EN PRUEBAS DE INMUNIDAD COMPRENDE UN TUBO QUE DEFINE UN LUMEN INTERNO Y QUE TIENE UNA MATRIZ DE FILTRO EN UN EXTREMO. LA MUESTRA SE COLOCA EN EL TUBO AGITADOR UTILIZANDO UNA PERA DE VACIO O UN DISPOSITIVO DE PRUEBA AUTOMATIZADO. LA MUESTRA SE FILTRA AL ENTRAR AL TUBO Y LUEGO SE FILTRA DE NUEVO CUANDO SE DESCARGA EN LA DIRECCION OPUESTA DEL TUBO. AL RETIRAR LAS PARTICULAS DE LA MUESTRA DEL LIQUIDO SE PUEDE MEJORAR LA PRUEBA. EL APLICADOR TAMBIEN PUEDE INCLUIR UN AGENTE REACTIVO DISPERSO EN UNA MATRIZ PERMEABLE, LO CUAL ES UTIL PARA INTRODUCIR UN AGENTE REACTIVO EN UNA MUESTRA U OTROS COMPONENTES LIQUIDOS DE LA MUESTRA. MIENTRAS UN COMPONENTE LIQUIDO DE LA PRUEBA SE INTRODUCE EN EL APLICADOR, EL REACTIVO SE MEZCLA CON EL LIQUIDO Y ESTE LO RECONSTITUYE REDUCIENDO, DE ESTE MODO, EL NUMERO DE PASOS NECESARIOS EN LA PRUEBA.
