Title (EN) METHOD AND APPARATUS FOR CONTINUOUS PERITONEAL CASCADE DIALYSIS AND HEMOFILTRATION (CPCD/H)
(FR) PROCEDE ET APPAREIL POUR DIALYSE PERITONEALE EN CASCADE CONTINUE ET HEMOFILTRATION (CPCD/H)
Abstract:
(EN) A continuous peritoneal dialysis is carried out by providing a dialyzer element (10) for being exposed within the peritoneal cavity having a filter membrane, and an interior dialysate passageway (12). The membrane maintains pores sufficient to allow diffusion of blood toxins. The dialyzer element (10) is implanted into the peritoneal cavity of a patient, a transfer fluid is infused into the patient's peritoneal cavity, and allowed to dwell. A continuous supply of substantially fresh dialysate fluid (26) is then directed into the interior dialysate passageway (12) of the dialyzer element whereby it is exposed to the transfer fluid by diffusion through the membrane. Toxins from the transfer fluid are diffused into the dialysate in the dialyzer element to form toxic dialysate fluid which is continuously removed from the dialyzer element.
(FR) La présente invention a trait à une dialyse péritonéale continue effectuée au moyen d'un élément de dialyse (10) pourvu d'une membrane filtrante (13/15) destinée à être exposée à l'intérieur de la cavité péritonéale et d'un passage intérieur de dialysat (12). Les pores de la membrane (13/15) de taille suffisamment grande permettent la diffusion des toxines du sang. On implante l'élément de dialyse (10) dans la cavité péritonéale du patient dans laquelle on envoie par perfusion un liquide de transfert, puis on assure un apport continu d'un dialysat liquide sensiblement frais (26) dans le passage intérieur de dialysat (12) de l'élément de dialyse. On dirige ensuite le dialysat le long dudit passage et on l'expose au liquide de transfert par diffusion à travers la membrane, les toxines du liquide de transfert se diffusant dans le dialysat contenu dans l'élément de dialyse pour former un dialysat liquide toxique. Les toxines sont extraites dudit élément de dialyse de façon continue.
