Power management system and method for maximizing heat delivered to dialysate in a dialysis machine

摘要

The amount of electrical power delivered to a dialysate heater in the dialysis machine is maximized without substantially exceeding a predetermined maximum allowed power consumption for the dialysis machine. The instantaneous power consumed by the machine is measured and compared to the maximum allowed power consumption. The excess of power beyond the instantaneous power consumed up to the maximum allowed power consumption is then made available to the heater. The worst case power consumption limitations of the dialysis machine components do not adversely affect the heat available from the heater. The rate at which dialysis treatments may progress may increase or the time required for dialysis treatments may decrease.
