Abstract

LA INVENCION SE REFIERE A UN APARATO DE HEMODIALISIS, QUE ESTA ABASTECIDO POR MEDIO DE UNA CONDUCCION 12 ANULAR DE ABASTECIMIENTO CON LIQUIDO DE DIALISIS O UN COMPONENTE DE LIQUIDO DE DIALISIS. PARA LA DESINFECCION DEL APARATO CON UN REFLUJO DE MEDIO DE DESINFECCION EN LA CONDUCCION DE ABASTECIMIENTO Y CON ELLO UNA AMENAZA DE QUE PUEDA IMPEDIRSE EL CASO DE LA CONDUCCION ANULAR DE ABASTECIMIENTO AL APARATO DE DIALISIS CONECTADO, DE FORMA QUE EL ORGANO 22 DE BLOQUEO TENGA FUGAS, SE PROPONE DE ACUERDO CON LA INVENCION, QUE ENTRE UN ORGANO DE BLOQUEO EN FORMA DE UNA PRIMERA VALVULA 22 MAGNETICA Y UNA VALVULA DE RETROCESO DISPUESTA DE MODO ADICIONAL SE IMPULSE EL VOLUMEN AMORTIGUADOR INCLUIDO CON UNA PRESION DEFINIDO, QUE ES CON PREFERENCIA LA PRESION EN EL TRAMO DE CONDUCCION TUBULAR QUE LO RODEA, Y QUE ESTA PRESION SE SUPERVISE POR MEDIO DE UN SENSOR P DE PRESION. LA SEÑAL GENERADA POR EL SENSOR DE PRESION P SE CONTROLA POR MEDIO DE UN MICROPROCESADOR 28. DE ACUERDO CON LA INVENCION SE HA PREVISTO DE FORMA ESPECIALMENTE VENTAJOSA, QUE LA PRESION PPV MAS ALTA NECESARIA EN EL VOLUMEN AMORTIGUADOR SE GENERE POR MEDIO DE UNA BOMBA 36, QUE ESTA PRESENTE EN FORMA DE MONTAJE YA CONOCIDO EN UN APARATO DE DIALISIS. PARA ELLO SE PROPONE UNA DISPOSICION DE VALVULA DE CONEXION APROPIADA.
