Abstract

L'INVENTION CONCERNE UN APPAREIL MEDICAL DE DIALYSE COMPRENANT UN DISPOSITIF 12 POUR MESURER LE CHANGEMENT DE POIDS DU PATIENT PENDANT LE TRAITEMENT, DES ORGANES 3, 4 POUR REGLER LA DIFFERENCE DE PRESSION ENTRE LE LIQUIDE DE DIALYSE ET LE SANG ET UN DISPOSITIF 11 POUR REGLER LA COMPOSITION DU LIQUIDE DE DIALYSE. SELON L'INVENTION, UN ORGANE 15 CONTROLANT LE TRAITEMENT DE DIALYSE EST CONNECTE AU DISPOSITIF 12. LA VALEUR DESIREE DE LA VITESSE DE VARIATION DU POIDS EXISTE DANS L'ORGANE 15 SOUS LA FORME D'UNE VALEUR DE CONSIGNE 14, L'ORGANE 15 EST CONCU POUR REGLER, A L'AIDE DU SIGNAL DE CHANGEMENT DE POIDS, LA DIFFERENCE DE PRESSION MECANIQUE ETOU OSMOTIQUE AGISSANT DE PART ET D'AUTRE DE LA MEMBRANE DE DIALYSE 2, DE TELLE MANIERE QUE LA VITESSE DE CHANGEMENT DE POIDS OBTENUE SOIT CONFORME A LA MOYENNE DE LA VALEUR DE CONSIGNE PREETABLIE.THE INVENTION RELATES TO A MEDICAL DIALYSIS APPARATUS INCLUDING A DEVICE 12 FOR MEASURING THE CHANGE IN PATIENT'S WEIGHT DURING THE TREATMENT, ORGANS 3, 4 FOR ADJUSTING THE PRESSURE DIFFERENCE BETWEEN THE DIALYSIS FLUID AND THE BLOOD, AND A DEVICE 11 FOR ADJUSTING THE COMPOSITION OF THE DIALYSIS LIQUID. ACCORDING TO THE INVENTION, A BODY 15 CONTROLLING THE DIALYSIS PROCESSING IS CONNECTED TO THE DEVICE 12. THE DESIRED VALUE OF THE VARIATION SPEED OF THE WEIGHT EXISTS IN THE BODY 15 IN THE FORM OF A SET VALUE 14, THE BODY 15 IS DESIGNED TO ADJUST, USING THE WEIGHT CHANGE SIGNAL, THE MECHANICAL AND OR OSMOTIC PRESSURE DIFFERENCE ACTING ON EACH OTHER OF DIALYSIS MEMBRANE 2, SO THAT THE WEIGHT CHANGE SPEED OBTAINED COMPLIES AT THE AVERAGE OF THE PRE-ESTABLISHED SETPOINT VALUE.
