  • Patent number: 10583236
    Abstract: A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in fluid communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood in a blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.

  • Patent number: 10071323
    Abstract: This disclosure generally relates to at least one reusable module of a sorbent cartridge in a sorbent dialysis system and a method of using the same. One of the drawbacks of a conventional sorbent dialysis system is the high cost. In one aspect of the invention, the sorbent cartridge contains at least one module for optionally recharging sorbent materials in-line with an optional bypass and conduits for the sorbent cartridge. The sorbent cartridge can have two or more modules that are connected to one another through connectors. The modules can be reusable and the sorbent materials contained in the modules can be recharged.
