Abstract

EL INVENTO SE REFIERE A UN METODO DE CONTROL DE LA ULTRAFILTRACION DE LA SENGRE GRACIAS AL CONTROL DEL BOMBEO DEL LIQUIDO EXTRAIDO DEL CIRCUITO DE LIQUIDO DE DIALISIS. EL BOMBEO SE EFECTUA GRACIAS A UNA BOMBA QUE EMITE UNOS IMPULSOS CORRESPONDIENTES, CADA UNO DE ELLOS, AL BOMBEO DE CIERTA CANTIDAD DE LIQUIDO. EL CONTROL SE EFECTUA REACTUALIZANDO PERMANENTEMENTE Y SIN DETENER ELFUNCIONAMIENTO DE LA BOMBA, EL VALOR DE LA CORRESPONDENCIA ENTRE LOS IMPULSOS EMITIDOS Y LA CANTIDAD DE LIQUIDO BOMBEADO. PARA ELLO, EL LIQUIDO SUMINISTRADO POR LA BOMBA (2) A CONTROLAR SE VIERTE EN UN DEPOSITO (5) DE CAPACIDAD CONOCIDAD ENTRE DOS DETECTORES DE NIVEL (6,7). UN CONTROLADOR (8) CUENTA LOS IMPULSOS EMITIDOS POR LA BOMBA DURANTE EL LLENADO DEL DEPOSITO (5) Y EFECTUA ENSEGUIDA LA CORRESPONDENCIA IMPULSO-CANTIDAD DE LOQUIDO BOMBEADO. EL INVENTO TIENE IGUALMENTE POR OBJETO UN DISPOSITIVO DE APLICACION DEL PROCEDIMIENTO
