    Abstract: Features for protecting against leaks in a fluid circuit are disclosed. In an embodiment, a first indicator of a leak is used to trigger confirmation by blood flow reversal and air detection in the blood circuit. A method for performing a blood treatment includes, at blood treatment machine, pumping blood to a patient through a first blood line. Further, at a controller of the blood treatment machine, a first signal is received, indicating a probability of a leak in the first blood line. Responsively to the first signal, the controller commands a leak verification operation and receives a second signal indicating whether a leak in the first blood line is verified. Further, a leak indicating signal is generated if the second signal indicates a leak is verified.

    Abstract: A treatment device system includes a treatment machine for performing a therapy on a patient, the treatment machine including at least one fluid conveyor and a controller, the controller having a first memory, to cause the at least one fluid conveyor to produce a therapeutic fluid by mixing purified water and at least one concentrate. The system also includes a water purifier with an internal central controller, in fluid communication with and providing the purified water to the treatment machine. A wired or wireless control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier, the controller of the treatment machine transmitting data via the control line to the internal central controller of the water purifier for control of the water purifier, the data provided based on at least one of the operator inputs received via the user interface.

    Abstract: An automated peritoneal dialysis system provides both cycler-assisted peritoneal dialysis treatment. The system includes a fluid preparation and treatment device with concentrate dilution components connected to a source of purified water and medicament concentrate. The treatment device has at least one mixing container connected via a pump and valves to the sources, the valves and the pump mixing and diluting the concentrate to form a medicament. Conductivity sensors are provided for fluid quality measurement, calibration, error trapping, and fluid characterization.

    Abstract: A system associated with a medical treatment device for detecting a condition of a patient includes an input device including at least a camera or a microphone. The system also includes a medical treatment device with a controller/classifier and at least one of flow controller, a pump, and/or an alarm output. The controller/classifier has at least a video-image processor or an audio processor configured to recognize a face and a body or to recognize changes in skin color, facial expression, or body position. The controller/classifier may also recognize speech and classify predefined normal and irregular sound patterns, and output state data corresponding thereto. The controller/classifier is connected to apply the state data to the at least one flow controller, pump, and/or alarm output. The controller/classifier is further adapted to control the at least one flow controller, pump, and/or alarm output responsively to the state data.
