Abstract

DISPOSITIVO PARA SEPARAR GAS DE SANGRE, ESPECIALMENTE EN UNA CORRIENTE SANGUINEA ASPIRADA DE UNA HERIDA DE UN PACIENTE. UNA CAMARA DE CENTRIFUGACION O CAMARA CICLONICA (8) FIJA, QUE SE ESTRECHA GRADUALMENTE EN FORMA DE EMBUDO ENTRE LA PROXIMIDAD DE UNA ENTRADA DE SANGRE (13) EN EL EXTREMO SUPERIOR DE LA CAMARA Y LA PROXIMIDAD DE UNA SALIDA DE SANGRE (15) EN EL EXTREMO INFERIOR DE LA CAMARA PARA LA REDUCCION DE LA PERDIDA DE ENERGIA DE ROTACION DE LA CORRIENTE SANGUINEA, LA CUAL ES ASPIRADA A TRAVES DE LA CAMARA DE CENTRIFUGACION (8) EN FORMA DE CORRIENTE SANGUINEA GIRATORIA ALREDEDOR DE UN EJE BASICAMENTE VERTICAL (10), SIN INVERSION DEL SENTIDO DE GIRO DE LA CORRIENTE SANGUINEA, POR EL REMOLINO O DEPRESION DE UN DISPOSITIVO DE ASPIRACION QUE PUEDE CONECTARSE A LA SALIDA DE SANGRE (15). LA DIRECCION DE LA CORRIENTE DE LA ENTRADA DE SANGRE (13) ES BASICAMENTE TANGENCIAL AL EJE DE ROTACION (10) Y ESTA DIRIGIDA SIMULTANEAMENTE DE MODO INCLINADO DE ARRIBA A ABAJO EN LA DIRECCION DE LA CORRIENTESANGUINEA AL INTERIOR DE LA CAMARA DE CENTRIFUGACION O CAMARA CICLONICA (8), CON UN ANGULO ( BE ) DE APERTURA HACIA ARRIBA RESPECTO AL EJE DE ROTACION INFERIOR A 90 .
