摘要： A fluid purification system has cells whose purifying capability can be regenerated. Some of the cells are arranged in series to reach a high level of purification. An automatic valve network is controlled to cycle the cells in a way that levels the loads on each, thereby maximizing the service interval for replacing expired cells, enabling all of the cells to be replaced at the same time after having each contributing approximately equally to the purification load, and operated such that at any one time, at least one cell is regenerated so as to enable continuous up-time.

摘要： Embodiments include a consumable medical device comprises a rigid cartridge to which a film is adhered to form a fluid channel and a damper chamber. A portion of the film forming the damper chamber has a wave-like shape adapted to roll onto a tip of a damper. The damper has a plunger to minimize peristaltic pressure in the channel. The cartridge may include conductivity measurement channels. Crosstalk may be minimized by using different frequencies or time division for reading the channels. A stable dialysate concentrate containing sodium lactate may be used or generated with the system. The concentrate may be formed to higher concentration than feasible with a single component concentrate by forming two containers of concentrate, each containing a fraction of a total quantity of sodium lactate required for a predefined number of dialysis.
