Various embodiments disclosed relate to a portable system for continuous renal replacement therapy. The present disclosure includes a system including a dialyzer, a blood circuit, a dialysate circuit, a cannister, a pump, and a housing. The housing can encase the system, including the dialyzer, circuits, cannister and pump. The system can be transformed between an active transport mode and a stationary mode. In the active transport mode, the components can be within the housing, allowing for patient mobility while attached to the system.

The disclosure relates to systems and methods for generating a brine solution using a salt bag for recharging zirconium phosphate in a reusable sorbent module. The salt bag can be a double layer bag. An inner water permeable bag can contain solid salts and can be surrounded by an outer water impermeable bag. Water can be added to dissolve the salts in the inner bag and the resulting solution can be collected as a brine solution for use in recharging the zirconium phosphate.

An adsorption structure provided in a flow path through which a fluid flows includes a plurality of cells that are structural units and are arranged side by side in the flow path, and the cells each include an inorganic adsorbent material that adsorbs a component included in the fluid. The cells are cuboids, the plurality of cells are arranged to be in a lattice form in a plane orthogonal to a flow path direction in which the flow path extends, and are arranged to be alternately stacked in the flow path direction. The cells each have a collision portion with which a flow of the fluid changes in a direction intersecting with the flow path direction in which the flow path extends. The collision portion is a surface intersecting with the flow path direction.

Provided is a method of designing a low-pressure chamber that provides a preset air pressure corresponding to a predetermined altitude. The method may include the steps of: calculating a predetermined error range of the preset air pressure, and calculating an amount and types of materials of a getter to be inserted into the low-pressure chamber based on the error range and a total volume of the low-pressure chamber.

Multi-functional materials for use in reversible, high-capacity hydrogen separation and/or storage are described. Also described are systems incorporating the materials. The multi-functional materials combine a hydrogen-absorbing material with a high-efficiency and a non-contact energy-absorbing material in a composite nanoparticle. The non-contact energy-absorbing material include magnetic and/or plasmonic materials. The magnetic or plasmonic materials of the composite nanoparticles can provide localized heating to promote release of hydrogen from the hydrogen storage component of the composite nanoparticles.

The present disclosure is directed to methods for scrubbing low levels of urea from aqueous solutions such as a dialysate from dialysis, and including blood and blood products, and devices capable of employing these methods.

Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H.sup.+ZP within a casing for a treatment; and after the treatment, refurbishing the H.sup.+ZP while maintained within the casing via (i) regenerating the non-disinfected H.sup.+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H.sup.+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H.sup.+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H.sup.+ZP while maintained within the casing. Multiple batch sorbent refubishing implementations are also disclosed.

An extracorporeal blood circulation device is provided with: a blood component adjuster; a blood purification device; a pipe system provided with a pump for supplying blood from a blood collecting part to the blood component adjuster, a valve for supplying a physiological saline solution, and a pressure gauge for sensing a pressure loss; a bypass pipe system for bypassing the blood component adjuster and supplying blood to the blood purification device; a pipe system for connecting the blood component adjuster and the blood purification device, the pipe system being provided with a pressure gauge for sensing a pressure loss; a pipe system provided with a valve for returning blood from the blood purification device to a reinfusion part and recovering the physiological saline solution, and a pressure gauge for sensing a pressure loss; and a control unit for switching to the bypass pipe system and switching to a reinfusion mode.
