A sorbent for a dialysis device where the pressure drop over across the layer is dependent of the size of the particles in the primary layer of immbolized uremic toxin-treating enzyme particles intermixed with cation exchange particles

摘要

590467 Disclosed is a sorbent for removing metabolic waste products from a dialysis liquid. The sorbent comprises a primary layer of immobilized uremic toxin-treating enzyme particles intermixed with cation exchange particles. The primary layer is arranged within the sorbent such that when in use, the pressure drop of the dialysate across the primary layer is dependent on the size of said cation exchange particles. The sorbent comprises a secondary layer of cation exchange particles and a tertiary layer of anion exchange particles intermixed with organic compounds absorber particles, where the secondary layer is disposed between said primary and said tertiary layer.
