Abstract

LA INVENCION TIENE POR OBJETO UN CIRCUITO HIDRAULICO PARA RIÑON ARTIFICIAL EN EL CUAL EL CIRCUITO DE LIQUIDO DE DIALISIS COMPORTA UN ULTRAFILTRO (10) DESTINADO A DESEMBARAZAR EL LIQUIDO DE DIALISIS DE LOS MICROORGANISMOS Y EVENTUALMENTE DE LOS ELEMENTOS PIROGENOS QUE PUEDE CONTENER. A FIN DE VERIFICAR PERMANENTEMENTE LA INTEGRIDAD Y LA EFICACIA DE LA MEMBRANA, SE DISPONE ARRIBA Y ABAJO DEL ULTRAFILTRO UN CAPTADOR DE PRESION (23, 24) CUYAS INFORMACIONES SON TRANSMITIDAS A UNA UNIDAD DE CONTROL (27) QUE DETERMINA ENTONCES LA PRESION TRANSMEMBRANARIA Y LA COMPARA CON UNOS VALORES DE UMBRAL PREDETERMINADOS. EN EL CASO DONDE LA PRESION TRANSMEMBRANARIA ALCANZA UNO DE LOS VALORES DE UMBRAL, LA UNIDAD (27) MANDA LA EMISION DE UNA SEÑAL VISUAL Y/O ACUSTICA Y EVENTUALMENTE LA PUESTA EN OBRA DE UN CIRCUITO DE DERIVACION DEL ULTRAFILTRO POR EL LIQUIDO DE DIALISIS.
