Abstract

UN CONTADOR DE BIOPERCEPCION (50) RECIBE UNA TIRA DE MUESTRA BIOMEDICA (10) QUE INCLUYE ELECTRODOS DE EXCITACION (14) Y SENTIDO (12) ELECTRICAMENTE AISLADOS O, ALTERNATIVAMENTE, UNA TIRA DE COMPROBACION. EL CONTADOR DE BIOPERCEPCION INCLUYE UN PRIMER Y SEGUNDO CONTACTOS (C, D) QUE ESTAN CONECTADOS POR UN ELECTRODO DE SENTIDO EN LA INSERCION DE UNA TIRA DE MUESTRA. UN CIRCUITO AMPLIFICADOR OPERACIONAL TIENE UNA PRIMERA Y SEGUNDA ENTRADA RESPECTIVAMENTE CONECTADAS AL PRIMER CONTACTO Y A UN POTENCIAL DE REFERENCIA, LA PRIMERA ENTRADA MANIFESTANDO EL POTENCIAL DE REFERENCIA COMO RESULTADO DE UNA RETROALIMENTACION EN EL AMPLIFICADOR OPERACIONAL. UN PROCESADOR (60) ESTA ACOPLADO AL SEGUNDO CONTACTO Y DETERMINA LA PRESENCIA DEL POTENCIAL DE REFERENCIA EN EL SEGUNDO CONTACTO CUANDO UN ELECTRODO DE SENTIDO INSERTADO CONECTA EL PRIMER Y SEGUNDO CONTACTOS. EL PROCESADOR TAMBIEN DISTINGUE ENTRE TIRAS DE MUESTRA Y DE COMPROBACION Y COMPRUEBA QUE HAYA UNA IMPEDANCIA ADECUADA ENTRE LOS ELECTRODOS DE SENTIDO Y EXCITACION DE UNA TIRA DE MUESTRA, PERMITIENDO ASI LA OPERACION DEL CONTADOR DE BIOPERCEPCION EN LA DOSIFICACION DE LA TIRA DE MUESTRA.
