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 and a water purifier 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, wherein the controller of the treatment machine transmits 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.

First claim

The invention claimed is:

1. A medical treatment system, comprising:
a treatment device for performing a therapy on a patient and configured to prepare a therapeutic fluid used in the therapy from at least one concentrate and from purified water, the treatment device configured to receive a disposable cartridge that holds at least a portion of a tubing set, the treatment device being further configured to convey fluid through the tubing set;
a water purification device in fluid communication with and providing the purified water to the treatment device;
a controller configured to cause production of the therapeutic fluid by mixing the purified water and the at least one concentrate; and
a user interface operably connected to the controller, the user interface configured to receive operator inputs, wherein
the controller controls operation of the treatment device and the water purification device,
and wherein the water purification device is configured to initiate transmission of at least one of state information, component life information, and alert information about the water purification device to the user interface, and the user interface displays the transmitted at least one of state information, component life information, and alert information.

2. The medical treatment system according to claim 1 , wherein
the therapy is renal replacement therapy.

3. The medical treatment system according to claim 1 , wherein
the water purification device generates the purified water before the purified water is mixed with the at least one concentrate.

4. The medical treatment system according to claim 1 , further comprising:
a housing that encloses the treatment device.

5. The medical treatment system according to claim 4 , wherein
the user interface is movable relative to the housing.

6. The medical treatment system according to claim 4 , wherein the housing further includes:
a door that closes over the disposable cartridge when the disposable cartridge is received by the treatment device.

7. The medical treatment system according to claim 1 , wherein
the treatment device is positioned vertically above the water purification device.

8. The medical treatment system according to claim 1 , further comprising:
the disposable cartridge that holds said at least a portion of the tubing set, the tubing set including a pumping tube segment.

9. The medical treatment system according to claim 8 , wherein the treatment device further includes:
a peristaltic pump configured to mate with the pumping tube segment when the disposable cartridge is received by the treatment device.

10. The medical treatment system according to claim 1 , wherein
the water purification device includes a depletable filter, and
the component life information relates to the depletable filter.

11. The medical treatment system according to claim 1 , wherein
the water purification device includes a urea level sensor, and
the state information is based on output of the urea level sensor.

12. The medical treatment system according to claim 1 , wherein
the water purification device includes two sensor modules in series and configured to redundantly measure a property of a liquid that is sensed by the two sensor modules, and
the water purification device initiates the transmission of the alert information when measurements from the two sensor modules are not in agreement with each other.
