Abstract:
1. A peritoneal dialysis device, comprising: a first fluid line that carries a fluid stream from a peritoneal cavity of a user; a processing arrangement that includes a sorbent system that is fluidly coupled to the first fluid line and that is configured to remove at least one toxin from the fluid stream to thereby allow production of a modified fluid stream; wherein the sorbent system includes an enzyme that is immobilized on a substrate with greater than Van der Waals forces; a separator fluidly coupled to the processing arrangement and configured to separate the modified fluid stream into a relatively protein-rich stream and a relatively protein-free stream, wherein the relatively protein-rich stream averages at least 15% (by vol) of the modified fluid stream over at least some period of time; a water recovery system fluidly coupled to the separator and configured to recover water from the relatively protein-free stream; and a second fluid line fluidly coupled to the separator and configured to introduce at least some of the relatively protein-rich stream into the peritoneal cavity.
