Title
(EN) A FILTER DEVICE FOR DIALYSIS APPLICATIONS
(FR) DISPOSITIF FILTRANT POUR APPLICATIONS DE DIALYSE
Abstract
(EN) The current invention relates to a peritoneal dialysis filter device, which comprises a housing comprising a first port and a second port, and a hollow fibre membrane formed from hollow hydrophilic fibres within the housing. When in use, a dialysate from a subject enters the filter device through the first port and exits via the second port in an outflow direction, and a regenerated dialysate from a sorbent system enters the filter device through the second port and exits via the first port in an inflow direction. Also disclosed herein is a peritoneal dialysis system comprising said filter device, a method for controlling dialysate flow in a peritoneal dialysis system, and a haemodialysis device.
(FR) La présente invention concerne un dispositif filtrant pour dialyse péritonéale, qui comprend un boîtier comprenant un premier orifice et un second orifice, et une membrane à fibres creuses formée à partir de fibres hydrophiles creuses à l'intérieur du boîtier. Lors de l'utilisation, un dialysat provenant d'un sujet entre dans le dispositif filtrant par le premier orifice et sort par le second orifice dans une direction d'écoulement sortant, et un dialysat régénéré provenant d'un système de sorbant entre dans le dispositif filtrant par le second orifice et sort par le premier orifice dans une direction d'écoulement entrant. L'invention concerne également un système de dialyse péritonéale comprenant ledit dispositif filtrant, un procédé de régulation de l'écoulement de dialysat dans un système de dialyse péritonéale, et un dispositif d'hémodialyse.
