Abstract

EQUIPO DE ELECTROCIRUGIA QUE POSEE UN CIRCUITO DE ALARMA (10) PARA DETECTAR CUANDO UN ELECTRODO DE PLACA DE RETORNO (5) ESTA INCORRECTAMENTE CONECTADO. SE CONECTAN DIVISORES CAPACITIVOS (11,14) ENTRE TIERRA Y CADA LINEA DE ALIMENTACION AL ELECTRODO ACTIVO (4) Y LA LINEA DE RETORNO DEL ELECTRODO DE PLACA (5). LAS SALIDAS DE LOS DIVISORES CAPACITIVOS SE DISTRIBUYEN A LAS DOS ENTRADAS DE UN AMPLIFICADOR DIFERENCIAL (22) QUE OFRECE UNA SALIDA A UNA ENTRADA DE UN COMPARADOR (30). CUANDO LA SALIDA DE UN AMPLIFICADOR (22) SUPERA UN FUENTE DE REFERENCIA (31), SE PRODUCE UNA SEÑAL DE ALARMA QUE IMPIDE EL SUMINISTRO DE CORRIENTE (1) Y EMITE UNA ALARMA AUDITIVA.
