    Abstract: This disclosure relates to dialysis venting devices and related methods. In some aspects, a dialysis system includes a fluid inlet line, a venting device in fluid communication with the fluid inlet line, and a fluid outlet line in fluid communication with the venting device. The venting device can include a housing defining a fluid chamber, a valve member disposed above the fluid chamber between a lower seat and an upper seat, and a pump that is operable to draw fluid into the fluid chamber from the fluid inlet line and to force fluid out of the fluid chamber into the fluid outlet line.

    Abstract: A dialysate regeneration system for removing contaminants from spent dialysate according to this invention includes a dialysate circulation flow path including a pump that pumps spent dialysate through the dialysate circulation flow path, a first cartridge adapted to remove contaminants from the spent dialysate, including a first cleaning solution inlet and a first cleaning solution outlet, a second cartridge adapted to remove urea from the spent dialysate, the second cartridge including semi-permeable hollow fibers adapted for transport of urea across the walls of the semi-permeable hollow fibers and adapted to retain at least calcium, magnesium, and sodium ions in the spent dialysate, and including a second cleaning solution inlet and a second cleaning solution outlet. Ancillary to the two cartridges, the dialysate regeneration system further includes a first dialysate cleaning flow path including a pump that pumps first cleaning solution from the first cleaning solution outlet of the first cartridge through a first cleaning stage to the first cleaning solution inlet of the first cartridge, and a second dialysate cleaning flow path including a pump that pumps second cleaning solution from the second cleaning solution outlet of the second cartridge through a second cleaning stage to the second cleaning solution inlet of the second cartridge.
