Abstract

This disclosure relates to remote control of dialysis machines. In certain aspects, a method includes receiving a request for a network connection from a dialysis machine and establishing the network connection with the dialysis machine. The method also includes 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.

First claim

What is claimed is:

1. A method performed by a data processor, the method comprising:
receiving a request for a network connection from a first dialysis machine;
establishing the network connection with the first dialysis machine;
receiving a designation of a level of access among a plurality of levels of access to the first dialysis machine granted to the data processor, wherein the level of access allows one or both of monitoring and controlling of the first dialysis machine;
receiving, from a first client device, a request to access the first dialysis machine;
authorizing the first client device to access the first dialysis machine based on an identity of one or both of the first client device and a user of the first client device;
receiving, from the first dialysis machine, information pertaining to an operation of the first dialysis machine;
providing, to the first client device, the information received from the first dialysis machine;
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;
providing, to the second client device, the information received from the second dialysis machine;
receiving, from the second client device, instructions for the second dialysis machine;
providing, to the second dialysis machine, the instructions received from the second client device for the second dialysis machine;
receiving, from a third client device, a request to access the second dialysis machine;
authorizing the third client device to access the second dialysis machine;
providing, to the third client device, the information received from the second dialysis machine;
receiving, from the third client device, instructions for the second dialysis machine; and
providing, to the second dialysis machine, the instructions received from the third client device for the second dialysis machine.

2. The method of claim 1 , further comprising:
receiving, from the first client device, instructions for the first dialysis machine; and
providing, to the first dialysis machine, the instructions received from the first client device for the first dialysis machine.

3. The method of claim 1 , further comprising assigning a proxy port for communication with each dialysis machine.

4. The method of claim 1 , wherein the first client device and the second client device are the same device.

5. The method of claim 1 , wherein authorizing the first client device comprises using an access control list stored on the data processor.

6. The method of claim 5 , wherein the access control list is configured to allow updating of a set of client devices that are authorized to access the first dialysis machine by updating, at the data processor, the access control list stored on the data processor.

7. The method of claim 1 , wherein the data processor is at a remote location from the first dialysis machine.

8. The method of claim 7 , wherein the data processor is at a clinic.

9. The method of claim 8 , wherein the first dialysis machine is at a home of a patient.

10. The method of claim 1 , wherein the first client device and the data processor are the same device.

11. The method of claim 1 , wherein authorizing the first client device to access the first dialysis machine comprises receiving a user login and password from the first client device.

12. The method of claim 1 , wherein the instructions received from the second client device for the second dialysis machine have a priority over the instructions received from the third client device for the second dialysis machine.

13. The method of claim 12 , wherein, when there is a conflict between the instructions received from the second client device for the second dialysis machine and the instructions received from the third client device for the second dialysis machine, the instructions received from the second client device are executed by the second dialysis machine, and the instructions received from the third client device are not executed by the second dialysis machine.

14. The method of claim 1 , wherein the information provided to the first client device comprises voice data.

15. The method of claim 1 , wherein the information provided to the first client device comprises one or both of video and audio.

16. The method of claim 15 , wherein the video and audio comprise information related to connections and components of the first dialysis machine.

17. The method of claim 1 , further comprising:
receiving, from the first client device, a video stream; and
providing, to a display of the first dialysis machine, the video stream.

18. The method of claim 17 , wherein the video stream includes audio.

19. The method of claim 1 , wherein the information pertaining to an operation of the first dialysis machine comprises data related to a dialysis treatment.

20. The method of claim 1 , wherein the information pertaining to an operation of the first dialysis machine comprises one or more of time remaining for a dialysis treatment, arterial pressure, venous pressure, transmembrane pressure, data related to ultrafiltration (UF), data related to dialysate, treatment status, and alarm information.

21. The method of claim 1 , wherein the information pertaining to an operation of the first dialysis machine is presented by an interface of the first client device.

22. The method of claim 21 , wherein the interface presents at least some of the information that is presented on a display of the first dialysis machine.

23. The method of claim 21 , wherein the interface presents controls for controlling the first dialysis machine.

24. The method of claim 1 , wherein the first client device is a mobile computing device.

25. The method of claim 2 , wherein the instructions for the first dialysis machine comprise one or more of initiating a dialysis treatment and pausing a dialysis treatment.

26. The method of claim 2 , wherein at least some of the instructions for the first dialysis machine are for setting one or more treatment parameters for a dialysis treatment.

27. The method of claim 2 , further comprising providing, to the first client device, a virtual control interface, wherein the instructions for the first dialysis machine are received from the first client device through the virtual control interface.

28. A method performed on a data processor of a first 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 first dialysis machine by the server;
providing a response to the access request;
receiving a designation of a level of access among a plurality of levels of access to the first dialysis machine granted to the server, wherein the level of access allows one or both of monitoring and controlling of the first dialysis machine;
authorizing a first client device to access the first dialysis machine based on an identity of one or both of the first client device and a user of the first client device; and
providing data to the server comprising information pertaining to an operation of the
