Abstract:
Disclosed are compositions and methods of regenerating or enhancing dialysate. Specifically, provided is a dialysate regeneration or enhancement component having a membrane with luminal spaces on each side wherein dialysate is circulated on one side of the membrane and waste dialysate is circulated on the other side. Renal tubule epithelial cells embedded on the membrane transport water, glucose, electrolytes, amino acids and other beneficial compounds from the waste dialysate across a membrane into unused dialysate, thereby reducing the amount of dialysate needed for peritoneal dialysis or enhancing the dialysate.
Abstract:
The present disclosure relates to an artificial, extracorporeal system for supporting the function of the liver of a patient suffering from liver failure, which is characterized in that it comprises a first high-flux or high cut-off hollow fiber membrane dialyzer which is perfused on the lumen side with the patient's blood and wherein a buffered aqueous solution comprising human serum albumin is passed in a continuous flow through the filtrate space of said first dialyzer, a second hollow fiber membrane dialyzer which removes water-soluble substances from the dialysate of said first dialyzer, and a third, integrated hollow fiber membrane dialyzer which is perfused with the retentate of second hemodialyzer and which allows the passage of certain amounts of albumin over the membrane wall into the filtrate space which is populated with adsorbent material. The system can be used for the treatment of acute liver failure and acute-on-chronic liver failure.
Abstract:
Die Erfindung betrifft ein Membranmodul (10a, 10b) zur Diffusionsdialyse von Fluiden, das mindestens zwei Strömungskanäle (8a, 8b) aufweist, die durch Aufwickeln von mindestens einem ersten Abschnitt (3a) mindestens einer Membranfolie und mindestens einem zweiten Abschnitt (3b) der mindestens einen Membranfolie auf einen Zentralkörper (1) gebildet sind, wobei eine Wicklung des mindestens einen ersten Abschnitts (3a) durch mindestens einen Abstandshalter (9) von einer Wicklung des mindestens einen zweiten Abschnitts (3b) beabstandet ist, wodurch sich beim Aufwickeln zwei voneinander getrennte Strömungskanäle (8a, 8b) bilden, die jeweils von der mindestens einen Membranfolie begrenzt sind.

Abstract:
A system and method improves the efficacy of blood filtration treatments such as hemodialysis, hemofiltration, and hemodiaflltration. A microfluidic device includes first and second channels separated by a permeable membrane. One of the channels is configured for blood flow and includes a protein gel disruption layer. The protein gel disruption layer includes a plurality of elements at least partially extending across the blood flow channel that reduce the formation of a boundary layer or gel layer at the blood-membrane interface.
Abstract:
A device includes (i) a housing defining an interior, wherein the interior has a blood compartment, a plasma compartment, and a fluid compartment; (ii) a first filter disposed in the interior of the housing, and (iii) a second filter disposed in the interior of the housing. The first filter separates at least a portion of the blood compartment from at least a portion of the plasma compartment. The first filter is configured to allow plasma components, but not cell components, of blood to pass through the first filter from the blood compartment to the plasma compartment. The second filter separates at least a portion of the plasma compartment from at least a portion of the fluid compartment. The second filter is configured to allow fluid and small molecules, but not larger components, to pass through the second filter from the plasma compartment to the fluid compartment. The device may include a sorbent in the plasma compartment to remove or reduce the concentration of selected components of the plasma. In embodiments, a system including the device includes a sorbent with which the plasma may be contacted.
Abstract:
L'invention concerne une machine de dialyse comprenant un dialyseur (1 ), un système d'amenée de dialysat (5) comprenant une ligne d'amenée (52) et un système d'évacuation (6) comprenant une ligne d'évacuation (62). La machine comprend des moyens de commande d'ultrafiltration (UF) et de rétrofiltration (RF). La ligne d'amenée comporte une restriction (520) et des moyens de mesure de la différence de pression (523, 524) aux bornes de ladite restriction. Ledit système d'amenée comprend aussi une poche ventricule (50), et des moyens de mise sous pression (70) de ladite poche ventricule (50). Ladite machine comprend un système (C5, C5') d'ouverture/fermeture de la ligne (62) d'évacuation et lesdits moyens de commande de rétrofiltration commandent la fermeture de la ligne (62) d'évacuation, et la pression appliquée à ladite poche ventricule (50), en fonction de la différence de pression mesurée aux bornes de la restriction (520), pour obtenir un débit de dialysat donné.
