Title (EN) A FLOW SYSTEM OF A DIALYSIS DEVICE AND A PORTABLE DIALYSIS DEVICE
(FR) SYSTÈME D'ÉCOULEMENT POUR DISPOSITIF DE DIALYSE ET DISPOSITIF PORTABLE DE DIALYSE
Abstract:
(EN) There is provided a flow system of a dialysis device comprising: a dialysate conduit which is capable of being in fluid communication with the peritoneal cavity of a patient's body and of being in fluid communication with a flow path, said flow path allowing dialysate to flow from a patient's body to a sorbent capable of removing contaminants within said dialysate in an outflow mode and in an inflow mode returning said dialysate substantially free of contaminants to said patient's body; a pump for moving said dialysate along said flow path in both the outflow mode and inflow mode; and a plurality of valves disposed along said flow path and being configured to, in the outflow mode, allow said dialysate to flow from said dialysate conduit to said sorbent for removal of contaminants therein, and in the inflow mode, allow dialysate substantially free of said contaminants to flow back to said dialysate conduit for transmission to said patient's body. There is also provided a portable dialysis device comprising a housing having means for attachment to a patient's body, the housing comprising the flow system disclosed above.
(FR) L'invention propose un système d'écoulement pour un dispositif de dialyse, qui comprend un conduit de dialysat qui peut être mis en communication fluidique avec la cavité péritonéale du corps d'un patient et en communication fluidique avec un parcours d'écoulement, ledit parcours d'écoulement permettant au dialysat de s'écouler du corps du patient vers un adsorbant capable de retirer les contaminants présents dans ledit dialysat en mode d'écoulement de sortie et de renvoyer ledit dialysat essentiellement débarrassé des contaminants vers ledit corps du patient en mode d'écoulement de retour, une pompe qui déplace ledit dialysat le long dudit parcours d'écoulement dans les deux modes, à savoir le mode d'écoulement de sortie et le mode d'écoulement de retour, et plusieurs soupapes disposées le long dudit parcours d'écoulement et configurées pour, en mode d'écoulement de sortie, permettre audit dialysat de s'écouler depuis ledit conduit de dialysat jusqu'audit adsorbant pour retirer les contaminants qui y sont présents et pour, en mode d'écoulement de retour, permettre au dialysat essentiellement débarrassé desdits contaminants de s'écouler en retour vers ledit conduit de dialysat pour être transmis dans ledit corps du patient. L'invention propose également un dispositif portable de dialyse qui comprend un boîtier doté de moyens qui permettent de le fixer au corps d'un patient, le boîtier comprenant le système d'écoulement divulgué ci-dessus.
