Title:
イオン促進型透析/濾過透析システム
Document Type and Number:
Japanese Patent JP4729224
Kind Code:
B2
Abstract:
A dual-stage filtration system and methods for using the same include first and second filtration cartridges particularly suited for hemodiafiltration and/or hemodialysis. As fluid enters the first filtration cartridge, the hydrogen ion concentration (pH) is reduced by exposing it to an acidic solution such as citric acid across a filter membrane. This stage allows for improved removal of certain toxins in the fluid, such as protein-bound substances that disassociate more readily from proteins at a lower pH. As the filtered fluid enters the second filtration cartridge, the pH of the fluid is restored to normal levels prior to infusion to a patient.
