Abstract

UN DISPOSITIVO PARA SEPARAR BURBUJAS GASEOSAS DE LIQUIDOS EN MEDICINA, EN ESPECIAL SANGRE, CONSTA DE UNA CAMARA CILINDRICA (1), DE UN CASQUILLO DE ENTRADA (6) DISPUESTO SEGUN EL EJE DE LA CAMARA, DE UN CASQUILLO DE SALIDA (7) Y DE UN COMPONENTE DE GUIA DE LA CORRIENTE CONECTADO AL CASQUILLO DE ENTRADA CON VARIOS CANALES DE CIRCULACION QUE SE EXTIENDEN EN UNA CURVA ESPACIAL DESDE EL SENTIDO LONGITUDINAL DE LA CAMARA A UN SENTIDO QUE EN ESENCIA ES TANGENCIAL A LAS PAREDES. LA TAPA (2) DE LA CAMARA (1) TIENE UNA ABERTURA (8) CERRADA CON UNA MEMBRANA HIDROFOBA (9). COMO LAS ABERTURAS DE SALIDA DE LOS CANALES DE CIRCULACION SE DISPONEN INMEDIATAMENTE DEBAJO DE LA TAPA (2), LA MEMBRANA ES ROCIADA CON EL LIQUIDO IMPULSADO SIN QUE SE FORMEN ZONAS MUERTAS. EL DISPOSITIVO PERMITE LA SEPARACION DE BURBUJAS DE AIRE CON GRAN SEGURIDAD, SIN QUE EXISTA EL PELIGRO DE QUE LA MEMBRANA HIDROFOBA SE ATASQUE POR EL CONTACTO CON LA SANGRE.
