Abstract

A home medical device system includes a home therapy machine for performing a home therapy on a patient; a user interface operably connected to the home therapy machine, the user interface receiving operator inputs; a water treatment device in fluid communication with the home therapy machine; and a data connection between the home therapy machine and the water treatment device, wherein the home therapy machine transmits data via the connection to the water treatment device for control of the water treatment device, the data provided based on at least one of the operator inputs received via the user interface.

First claim

The invention is claimed as follows:

1. A medical device system comprising:
a therapy machine for performing a therapy on a patient, the therapy machine including at least one mixing pump and a processor and memory programmed to cause the at least one mixing pump to produce a medical fluid by mixing purified water and a dry, liquid, or slurried concentrate;
a user interface operably connected to the therapy machine, the user interface receiving operator inputs;
a water treatment device in fluid communication with and providing purified water to the therapy machine, the water treatment device including a processor and memory separate from the processor and memory of the therapy machine and configured to control preparation of the purified water; and
a wired or wireless data connection providing two way communication between the processor and memory of the therapy machine and the processor and memory of the water treatment device for at least the control by the processor and memory of the water treatment device of the preparation of the purified water, wherein the processor and memory of the therapy machine is configured to transmit data via the data connection to the processor and memory of the water treatment device for control of the water treatment device, the data provided based on at least one of the operator inputs received via the user interface.

2. The medical device system of claim 1 , wherein the water treatment device transmits to the therapy machine at least one of: (i) state information, (ii) component life information, (iii) self test results, (iv) alert information or (v) version information.

3. The medical device system of claim 2 , wherein the user interface displays the transmitted at least one of: (i) the state information, (ii) the component life information, (iii) the self test results, (iv) the alert information or (v) the version information.

4. The medical device system of claim 1 , in which the therapy machine transmits to the water treatment device at least one of: (i) state change requests, (ii) status queries, (iii) flowrate change requests, (iv) software upgrades or downgrades, or (v) file transfers.

5. The medical device system of claim 4 , wherein the user interface displays at least one of: (i) the state change requests, (ii) the status queries, (iii) the flowrate change requests, (iv) the software upgrades or downgrades, or (v) the file transfers.

6. The medical device system of claim 1 , wherein the at least one operator input leading to the transmitted data concerns a water treatment device parameter.

7. The medical device system of claim 1 , wherein the at least one operator input leading to the transmitted data concerns a therapy machine parameter, the transmitted data an automatic result of a change in the therapy machine parameter.

8. A medical fluid therapy system comprising:
a therapy machine for performing a therapy on a patient and including at least one mixing pump, the therapy machine including a processor and memory configured to produce a medical fluid by causing the at least one mixing pump to mix purified water and a dry, liquid, or slurried concentrate;
a user interface operably connected to the therapy machine, the user interface receiving operator inputs;
a water treatment device in fluid communication with and providing purified water to the therapy machine, the water treatment device including a processor and memory separate from the processor and memory of the therapy machine and configured to control preparation of the purified water;
a server in data flow communication with the therapy machine; and
a wired or wireless data connection providing two way communication between the processor and memory of the therapy machine and the processor and memory of the water treatment device for at least the control by the processor and memory of the water treatment device of the preparation of the purified water, wherein the processor and memory of the therapy machine is configured to transmit data via the data connection to the processor and memory of the water treatment device, the data based on a therapy prescription sent from the server to the therapy machine.

9. The medical fluid therapy system of claim 8 , wherein the transmitted data is for control of the water treatment device.

10. The medical fluid therapy system of claim 8 , wherein the therapy prescription specifies the data transmitted from the therapy machine to the water treatment device.

11. The medical fluid therapy system of claim 8 , wherein the therapy prescription specifies an operating parameter for the therapy machine, the transmitted data based on the specified operating parameter.

12. The medical fluid therapy system of claim 11 , wherein the therapy machine determines the transmitted data based on the specified operating parameter.

13. The medical fluid therapy system of claim 11 , wherein the water treatment device uses the data to determine a corresponding operating parameter for the water treatment device.

14. The medical fluid therapy system of claim 8 , wherein the server is configured to send a software upgrade to the therapy machine, the software upgrade if meant for the water treatment device forwarded by the therapy machine to the water treatment device.

15. The medical fluid therapy system of claim 14 , wherein the software upgrade is automatically installed on the water treatment device or installed upon acceptance by a user via the user interface.

16. The medical fluid therapy system of claim 8 , wherein the server is in data communication with a service computer, the service computer enabling a service person to access the water treatment device via the data connection with the therapy machine to perform at least one service procedure.

17. The medical fluid therapy system of claim 8 , wherein upon startup, the therapy machine is configured to determine if the water treatment device is in a hibernation mode and if so to perform a startup procedure not involving the water treatment device.

18. The medical fluid therapy system of claim 8 , which is configured to enable a user via the user interface to run at least one self test for the therapy machine and at least one self test for the water treatment device.

19. A medical fluid therapy system comprising:
a therapy machine for performing a medical fluid therapy on a patient and including at least one mixing pump, the therapy machine including a processor and memory configured to produce a medical fluid by causing the at least one mixing pump to mix purified water and a dry, liquid, or slurried concentrate;
a user interface operably connected to the therapy machine, the user interface receiving operator inputs;
a water treatment device in fluid communication with and providing purified water to the therapy machine, the water treatment device including a processor and memory separate from the processor and memory of the therapy machine and configured to control preparation of the purified water;
a server in data flow communication with the therapy machine; and
a wired or wireless data connection providing two way communication between the processor and memory of the therapy machine and the processor and memory of the water treatment device for at least the control by the processor and memory of the water treatment device of the preparation of the purified water, wherein the processor and memory of the water treatment device is configured to transmit data via the data connection to the processor and memory of the therapy machine, which forwards the data to the ser
