Abstract
A dialysis machine includes a control unit having a user interface; a heater(s) located separate from the control unit; a supervisory processor located with the control unit; a delegate control processor located with the heater(s), the delegate control processor in communication with the supervisory processor and configured to receive load cell, heater(s) plate and supply bag temperature sensor inputs; and a sub-delegate heater(s) processor in communication with the control processor and configured to control power to the heater(s). The machine can also include primary and secondary monitoring processors that perform a safety check to the control processing and monitor the load cell.
