Abstract
LA INVENCION TRATA DE UN DISPOSITIVO PARA SEPARAR GAS DE SANGRE QUE CONTIENE GAS. SE PREVE UNA CAMARA DE TURBULENCIA DE CICLON NO ROTATORIA, A TRAVES DE LA CUAL PUEDE CONDUCIRSE SANGRE QUE CONTIENE GAS EN FORMA DE UNA CORRIENTE TURBULENTA DE CICLON, A FIN DE LLEVAR A CABO UNA SEPARACION MEDIANTE FUERZAS DE CENTRIFUGADO EN UNA FASE SANGUINEA EN LA ZONA DE LA CORRIENTE TURBULENTA DE CICLON RADIAL EXTERIOR Y EN UNA FASE GASEOSA EN LA ZONA DE LA CORRIENTE TURBULENTA DE CICLON RADIAL INTERIOR. LA ENTRADA DEL CICLON ESTA FORMADA POR UN CANAL DE ENTRADA DE SANGRE EN FORMA DE ROSCA, QUE DISCURRE EN CIRCULO, QUE AL MENOS EN UNA PARTE DE SU LONGITUD, EN EL SENTIDO DE LA CORRIENTE, ESTA CONFIGURADO DE MANERA QUE SE VA ESTRECHANDO A MODO DE EMBUDO, A FIN DE ACELERAR LA CIRCULACION DE LA SANGRE QUE CONTIENE GAS. PARA ELIMINAR LA FASE GASEOSA, EN EL CENTRO INTERIOR RADIAL DE LA VIA DE LA CORRIENTE TURBULENTA DE CICLON HAY DISPUESTA UNA SALIDA DE GAS Y ESTA ORIENTADA EN DIRECCION OPUESTA RESPECTO A LA DIRECCION DE MOVIMIENTO AXIAL DEL CICLON.
