Abstract

A treatment device system includes a treatment machine for generating a custom peritoneal dialysis solution and has at least one fluid conveyor. The treatment machine has a controller with a first memory and is configured to produce the custom peritoneal dialysis solution by causing the fluid conveyor to mix purified water and at least one concentrate. A water purifier is in fluid communication with, and provides the purified water to, the treatment machine. The water purifier has an internal central controller to control preparation of the purified water, the internal central controller having a second memory. Further, the controller of the treatment machine transmits data, based on a prescription sent from a server to the treatment machine, via a wired or wireless control line to the internal central controller of the water purifier.

First claim

The invention claimed is:

1. A treatment device system, comprising:
a treatment machine for generating a custom peritoneal dialysis solution and including at least one fluid conveyor, the treatment machine comprising a controller, the controller comprising a first memory, the treatment machine configured to produce the custom peritoneal dialysis solution by causing the at least one fluid conveyor to mix purified water and at least one concentrate;
a user interface operably connected to the treatment machine, the user interface configured to receive operator inputs;
a water purifier in fluid communication with and providing the purified water to the treatment machine, the water purifier including an internal central controller to control preparation of the purified water, the internal central controller comprising a second memory;
a server communicatively coupled with the treatment machine; and
a wired or wireless control line providing 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, the data provided based on a prescription sent from the server to the treatment machine.

2. The treatment device system of claim 1 , wherein the prescription specifies a control signal for control of the water purifier.

3. The treatment device system of claim 1 , wherein the prescription specifies control signals transmitted from the treatment machine to the water purifier.

4. The treatment device system of claim 1 , wherein the prescription specifies a command for the treatment machine, the data provided based on the specified command.

5. The treatment device system of claim 4 , wherein the treatment machine determines the data provided based on the specified command.

6. The treatment device system of claim 4 , wherein the water purifier uses the data to determine an operating parameter for the water purifier.

7. The treatment device system of claim 1 , wherein the server is configured to send a software upgrade to the treatment machine, the software upgrade, if meant for the water purifier, forwarded by the treatment machine to the water purifier.

8. The treatment device system of claim 1 , wherein a software upgrade is automatically installed on the water purifier or installed upon acceptance by a user via the user interface.

9. The treatment device system of claim 1 , wherein the server is in data communication with a service computer, the service computer enabling a service person to access the water purifier via the control line with the treatment machine to perform at least one service procedure.

10. The treatment device system of claim 1 , wherein upon startup, the treatment machine is configured to determine if the water purifier is in a hibernation mode and, if so, to perform a startup procedure not involving the water purifier.

11. The treatment device system of claim 1 , which is configured to run at least one self-testing procedure for the treatment machine and at least one self-testing procedure for the water purifier.

12. The treatment device system of claim 1 , wherein the water purifier includes a user interface in communication with the internal central controller of the water purifier, and wherein the user interface of the water purifier operates the water purifier if the wired or wireless control line between the controller of the treatment machine and the internal central controller of the water purifier is broken.
