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 system comprising:
a network device;
a dialysis machine configured to connect to the network device; and
a remote device configured to connect to the network device,
wherein the network device is configured to:
receive, from the dialysis machine, through a network, data related to an operation of the dialysis machine,
generate a virtual control for the dialysis machine based on the received data, the virtual control comprising computer program instructions that when executed, form a user interface representing the operation of the dialysis machine,
determine whether the remote device is authorized to send or receive data to or from the dialysis machine, and
in response to determining that the remote device is authorized to send or receive data to or from the dialysis machine, transmit the virtual control to the remote device,

wherein the remote device is configured to run the virtual control to generate a user interface presenting the operation of the dialysis machine, the user interface comprising selectable control features for providing an instruction to control the dialysis machine.

2. The system of claim 1 , wherein the data related to the operation of the dialysis machine includes treatment data.

3. The system of claim 2 , wherein the virtual control is generated using the treatment data received from the dialysis machine.

4. The system of claim 2 , wherein the user interface is presented on a display of the remote device, and presents one or more of treatment time remaining, arterial pressure, venous pressure, transmembrane pressure, ultrafiltration data, or dialysate data.

5. The system of claim 2 , wherein the user interface presents the treatment data on the remote device in real-time while the dialysis machine performs a treatment on a patient.

6. The system of claim 1 , wherein the user interface presents one or both of an alarm or an alert.

7. The system of claim 1 , wherein the user interface is configured to present information that is presented on a display of the dialysis machine.

8. The system of claim 7 , wherein the user interface is configured to present the same information that is presented on the display of the dialysis machine.

9. The system of claim 1 , wherein at least some of the selectable control features in the user interface are part of a control panel configured to receive input for the instruction to control the dialysis machine.

10. The system of claim 1 , wherein the dialysis machine is located at a home of a patient.

11. The system of claim 1 , wherein the network device includes a server.

12. The system of claim 1 , wherein the network device uses a web services infrastructure.

13. The system of claim 1 , wherein the network device assigns a proxy for the dialysis machine, and communicates with the dialysis machine through the proxy.

14. The system of claim 13 , wherein the proxy is a proxy server, and is configured to provide the virtual control to the remote device.

15. The system of claim 1 , wherein the dialysis machine is located at a home of a patient and the remote device is located remotely from the home of the patient.

16. The system of claim 1 , wherein the remote device is one or more of a computer, a mobile phone, a tablet computer, a laptop, a netbook or a smartphone.

17. The system of claim 1 , wherein the instruction to control the dialysis machine is stored on a universal serial bus (USB) device.

18. The system of claim 1 , wherein the instruction to control the dialysis machine is transmitted to the dialysis machine over the network.

19. The system of claim 18 ,
wherein the network device is further configured to:
receive, from the remote device, the instruction to control the dialysis machine, wherein the remote device transmits the instruction in response to receiving a selection of at least one of the control features by a user, and
transmit the instruction to the dialysis machine, and
wherein the dialysis machine is configured to receive and execute the instruction.

20. The system of claim 1 , wherein the user interface shows different screens at different stages of the operation of the dialysis machine.
