Abstract

UN CONTADOR DE BIOPERCEPCION (22) RECIBE UNA TIRA DE MUESTRA (10) QUE INCLUYE ELECTRODOS DE EXCITACION Y SENTIDO ELECTRICAMENTE AISLADOS (12, 14) UNIDOS POR UNA ZONA DE REACCION. CUANDO SE PONE UNA GOTA DE LIQUIDO DE MUESTRA BIOLOGICA EN LA ZONA DE REACCION, SE LLEVAN A CABO UNA PLURALIDAD DE PRUEBAS DE FALLO/SEGURIDAD. UN CIRCUITO QUE DETECTA EL TAMAÑO DE LA GOTA COLOCADA EN LA ZONA DE REACCION REALIZA UNA PRUEBA DEL TAMAÑO DE LA GOTA. EL CIRCUITO DETECTA UNA GOTA QUE HAYA SIDO COLOCADA EN LA ZONA DE REACCION Y ADEMAS MIDE UN NIVEL DE ACTUAL DE PRUEBA, DESPUES DE UN RETARDO, PARA DETERMINAR QUE EL TAMAÑO DE LA GOTA ES SUFICIENTE PARA PERMITIR LA HIDRATACION DE REACTIVOS EN LA ZONA DE REACCION.
