Abstract

La présente invention concerne un appareil et des procédés d'utilisation de systèmes de traitement hématologique par transfert de masse, tels que les unités d'hémodialyse, d'hémofiltration ou d'oxygénation du sang. Cet appareil comprend une pompe qui possède un orifice d'entrée, un orifice de sortie, un premier et un second réservoir, une vanne qui sélectivement interconnecte les réservoirs aux orifices d'entrée et de sortie. Un contrôleur synchronise le fonctionnement de cette vanne, du premier et du second réservoir de façon à obtenir simultanément des plans de flux de déplacement d'entrée ou de sortie indépendants l'un de l'autre. Cet appareil peut aussi être mis en oeuvre dans une configuration en réseau afin de permettre de télécharger des paramètres clé relatifs à une séance de traitement d'un patient avec cette unité de traitement hématologique, chez un fournisseur de service santé afin d'obtenir une évaluation rapide.
