Title (EN) METHODS AND SYSTEM OF GENERATING RAPIDLY VARYING PRESSURE AMPLITUDES IN FLUIDIC CIRCUITS IN A DIALYSIS TREATMENT SYSTEM
(FR) PROCÉDÉS ET SYSTÈME DE GÉNÉRATION D'AMPLITUDES DE PRESSION VARIANT RAPIDEMENT DANS DES CIRCUITS FLUIDIQUES DANS UN SYSTÈME DE TRAITEMENT PAR DIALYSE
Abstract:
(EN) The present specification describes a modular, portable hemofiltration system, for providing improved clearance levels of blood toxins, which includes at least one roller pump that is designed and operated to generate a rapidly varying pressure profile of fluid within at least a blood circuit of the hemofiltration system.
(FR) La présente invention concerne un système d'hémofiltration portable modulaire, permettant de fournir des niveaux de clairance améliorés de toxines du sang, qui comprend au moins une pompe à rouleaux qui est conçue et qui fonctionne de sorte à générer un profil de pression de fluide variant rapidement au sein d'au moins un circuit sanguin du système d'hémofiltration.
