Abstract

EL SISTEMA INCLUYE UNA VALVULA DE CONTROL DE FLUJO Y UNA ANTECAMARA, ESTA DISPUESTO PARA CONTROLAR LA LIBERACION DE FLUIDOS DE CUERPO ENTRAMPADOS. LA VALVULA DE CONTROL DE FLUJO INCLUYE UN PAR DE BASES DE PLASTICO MOLDEADO, RESPECTIVAMENTE, ADYACENTES A UNA ENTRADA Y UNA SALIDA DE UNA VALVULA, CUYAS BASES SE SITUAN DENTRO DE UN ALOJAMIENTO FLEXIBLE. CADA BASE INCLUYE UNA CARCASA EXTERIOR, UNA VALVULA DE MEMBRANA POSICIONADA DENTRO DE LA CARCASA, Y UN DISPSOSITIVO DE CONTROL DE FLUJO. LOS DISPOSITIVOS DE CONTROL DE FLUJO INCLUYEN UN SOPORTE CENTRAL EN CUÑA RIGIDO Y UNA MEMBRANA RESISTENTE FLEXIBLE SEPARADA POSICIONADA EN EL SOPORTE CENTRAL. UN PRIMER DISPOSITIVO DE CONTROL DE FLUJO ES CAPAZ DE SELECTIVAMENTE OBSTRUIR LA ENTRADA DE LA VALVULA, PERO SE ESPACIA NORMALMENTE DESDE SU BASE PARA PERMITIR QUE EL FLUJO DE FLUIDO LIBRE ATRVIESE LA ENTRADA. EL SEGUNDO MIEMBRO DE CONTROL DE FLUJO TIENE NORMALMENTE UNA FORMA ARQUEADA Y PARCIALMENTE RESISTENTE PARA CONTACTAR CON SU RESPECTIVA BASE GENERALMENTE A LO LARGO DEL BORDE MAS EXTERNO DE LA MEMBRANA DE FORMA QUE PERMITA SOLO EL CONTROL DEL FLUJO EN UN CAMINO A TRAVES DE LA VALVULA. LA ANTECAMARA PERMITE LA INYECCION DE MEDICACION EN UNA MANIOBRA DENTRO ENTRE UN CATETER PROXIMO Y UNA VALVULA DE CONTROL DE FLUJO DISTANTE, E IMPULSANDO LA MEDICACION EN CADA UNA DE LAS DIRECCIONES. ADICIONALMENTE, SE DISPONE DE UN METODO PARA MONTAJE DEL SISTEMA DE UNA MANERA SENCILLA Y ECONOMICA, QUE UTILIZA UNO DISPOSITIVOS TAPADOS PARA ANCLAR LOS COMPONENTES EN UN LUGAR PREVIO PARA ASEGURAR DE FORMA ADHESIVA EL TUBO AL CIERRE FLEXIBLE.
