Abstract

LA INVENCION SE COMPONE DE UN DISPOSITIVO (10) DOSIFICADOR PARA DOSIFICACION VOLUMETRICA DE UN ADITIVO LIQUIDO, QUE SE AÑADE EN UNA PRIMERA CONDUCCION (11) DE TUBO FLEXIBLE, EN PARTICULAR SANGRE ASPIRADA, A TRAVES DE UNA SEGUNDA CONDUCCION (12) DE TUBO FLEXIBLE QUE DESEMBOCA DE FORMA DIRECTA O INDIRECTA EN LA PRIMERA CONDUCCION FLEXIBLE EN UNA RELACION DE VOLUMEN DETERMINADA. ESPECIALMENTE SE HA PREVISTO EL DISPOSITIVO (10) DE ACUERDO CON LA INVENCION PARA LA DOSIFICACION VOLUMETRICA DE UN LIQUIDO (ACD) DE ANTICOAGULACION O DE UN ACELERADOR DE SEDIMENTACION EN UN SISTEMA PARA LA RECOLECCION Y RETRANSFUSION DE SANGRE, QUE MUESTRA AGUAS ABAJO DEL LUGAR (14) DE DESEMBOCADURA UN TRAMO TUBULAR O MANGUERA FLEXIBLE QUE SE EXTIENDE ASI COMO ADEMAS AGUAS ABAJO DEL TUBO (16) DE GOTEO EN LA CAMARA (18) DE GOTEO CONECTADA CON EL Y CON UNA BARRERA (30) DE LUZ, CUYA DIRECCION DE EFECTO ESTA DISPUESTA DE FORMA TRANSVERSAL CON RESPECTO AL TRAMO DE CAIDAS DE LAS GOTAS. PARA EL CIERRE DE LA DOSIFICACION FALTANTE POR MOTIVOS DE UNA VISCOSIDAD CAMBIANTE DEL LIQUIDO QUE FLUYE EN LA PRIMERA CONDUCCION (11) DE TUBO FLEXIBLE Y CON ELLO PARA EL CIERRE DE OTRO TAMAÑO DE GOTEO, SE PROPONE DE ACUERDO CON LA INVENCION, QUE SE PREVEA DE DOS MEDIOS (22,23) DE VALVULA CONTROLABLES, A PARTIR DE LOS CUALES SE ACOPLAN DE FORMAN CONJUNTA EN UNA DE AMBAS CONDUCCIONES (11,12) DE TUBERIA FLEXIBLE, Y ESTOS MEDIOS (22,23) DE VALVULA SE CONTROLAN DE FORMA ALTERNATIVA EN UNA UNIDAD (CPU,RAM) DE CONTROL Y DE CONTADO, DE TAL FORMA QUE SE CONECTAN SOLAMENTE EN UNA DE AMBAS CONDUCCIONES (11,12) FLEXIBLES CONOCIDAS PARA UN ACCESO DE PASO AL MISMO TIEMPO. EL MOTIVO DEL EFECTO CAPILAR EN EL LIQUIDO QUE PERMANECE EN LA TUBERIA (16) DE GOTEO ES EFECTUAR CON ELLO UNA CONSTANTE DE VOLUMEN ENTRE LAS GOTAS QUE CAEN EN EL EXTREMO INFERIOR DEL TUBO (16) DE GOTEO Y UN ADITIVO, QUE SE DOSIFICA EN EL EXTREMO SUPERIOR DEL TUBO (16) DE GOTEO.
