Abstract

A system is disclosed having a server, a dialysis machine configured to connect to the server through a network and client device configured to connect to the server through the network. In one embodiment, the server is configured to maintain an access list to determine whether the client device is authorized to connect to the dialysis machine. The server is further configured to provide a connection for transfer of data between the dialysis machine and the client device. Various methods of accessing the network using the system components are further disclosed.

Claims

1. A method performed by a data processor, the method comprising:

receiving a request for a network connection from a dialysis machine;

establishing the network connection with the dialysis machine;

receiving, from a client device, a request to access the dialysis machine;

authorizing the client device to access the dialysis machine;

receiving, from the dialysis machine, information pertaining to an operation of the dialysis machine; and

providing, to the client device, the received information.

2. The method of claim 1, which further includes receiving, from the client device, instructions for the dialysis machine, and providing, to the dialysis machine, the received instructions.

3. The method of claim 1, which further includes receiving a connection from a second dialysis machine;

receiving, from a second client device, a request to access the second dialysis machine;

authorizing the second client device to access the second dialysis machine;

receiving, from the second dialysis machine, information pertaining to an operation of the second dialysis machine; and

providing, to the second client device, the information received from the second dialysis machine.

4. The method of claim 3, which includes assigning a proxy port for communication with each dialysis machine.

5. The method of claim 3, wherein the client device and the second client device are the same device.

6. The method of claim 1, wherein authorizing the client device includes using an access list stored on the data processor.

7. The method of claim 6, wherein the access list is configured to allow updating of a set of client devices that are authorized to access the dialysis machine by updating, at the data processor, the access list stored on the data processor.

8. The method of claim 1, wherein the data processor is located remotely from the dialysis machine.

9. The method of claim 8, wherein the data processor is located at a clinic.

10. The method of claim 9, wherein the dialysis machine is located at a home of a patient.

11. The method of claim 1, wherein the client device is a personal digital assistant.

13. The method of claim 11, which further includes receiving instructions from the server, and executing the received instructions.

14. The method of claim 11, wherein the dialysis machine is located remotely from the server.

12. A method performed on a data processor of a dialysis machine, the method comprising:

sending a request, to a server, to establish a network connection with the server;

receiving an access request from the server, the access request requesting access to the dialysis machine by the server;

providing a response to the access request;

providing data to the server comprising information pertaining to an operation of the dialysis machine.

15. A system comprising:

a server;

a dialysis machine configured to connect to the server through a network;

a client device configured to connect to the server through the network; and

wherein the server is configured to maintain an access list to determine whether the client device is authorized to connect to the dialysis machine, and

the server is configured to provide a connection for transfer of data between the dialysis machine and the client device.

16. The system of claim 15, wherein the server is further configured to

receive a request for a network connection from the dialysis machine;

establish the network connection with the dialysis machine;

receive, from the client device, a request to access the dialysis machine;

authorize the client device to access the dialysis machine;

receive, from the dialysis machine, information pertaining to an operation of the dialysis machine; and

provide, to the client device, the received information.

17. The system of claim 15, wherein the server is further configured to

receive, from the client device, instructions for the dialysis machine;

and

providing, to the dialysis machine, the received instructions.

18. The system of claim 15, which includes

a second dialysis machine;

and

a second client device,

wherein the server is further configured to

receive a connection from the second dialysis machine;

receive, from the second client device, a request to access the second dialysis machine;

authorize the second client device to access the second dialysis machine;

receive, from the second dialysis machine, information pertaining to an operation of the second dialysis machine; and

provide, to the second client device, the information received from the second dialysis machine.

19. The system of claim 18, wherein the server is further configured to assign a proxy port for communication with each dialysis machine.

20. The system of claim 18, wherein the client device and the second client device are the same device.

21. The system of claim 15, wherein the access control list is configured to allow an updating of a set of client devices that are authorized to access the dialysis machine by updating, at the server, the access list stored on the server.

22. The system of claim 15, wherein the data processor is located remotely from the dialysis machine.

23. The system of claim 22, wherein the server is located at a clinic.

24. The system of claim 23, wherein the dialysis machine is located at a home of a patient.
