Title (EN) APPARATUS AND METHOD FOR HIGH EFFICIENCY HEMOFILTRATION
(FR) APPAREIL ET PROCEDE D'HEMOFILTRATION A HAUTE EFFICACITE
Abstract:
(EN) Disclosed herein is an apparatus that efficiently clears solutes from blood of patient with renal disease solely by convection and with a single filter that includes a hemofilter (22), a blood pump (12) for drawing blood from a patient and propelling the blood into a mixing and detention chamber (20) where the blood and a non-isosmotic diluent are mixed and are allowed to approach or reach equilibrium, a mixing element for creating turbulence in the mixing/detention chamber (20), and suitable tubings (10, 26) for carrying the pumped blood to and from the patient. Methods for utilizing the apparatus are also disclosed.
(FR) La présente invention concerne un appareil qui élimine les solutés du sang d'un patient atteint d'une maladie rénale par convection uniquement et au moyen d'un seul filtre comprenant un hémofiltre (22), une pompe à sang (12) qui extrait le sang d'un patient et le propulse dans une chambre de mélange et de rétention (20) où le sang est mélangé à un diluant non isosmotique jusqu'à ce qu'ils approchent ou atteignent un équilibre, un élément mélangeur destiné à créer une turbulence dans la chambre de mélange/rétention (20), et des tubes appropriés (10,26) destinés à transporter le sang pompé depuis le patient et vers celui-ci. L'invention se rapporte également à des procédés d'utilisation de l'appareil.
