Abstract

This patent application relates generally to processing devices in the medical device area.

Claims

1. A method performed by one or more user interface processing devices comprising:

switching focus of one or more user interfaces from a first processing device to a second processing device or from the second processing device to a first processing device,

wherein the first processing device is configured to control and to monitor medical functions of a dialysis medical device, and wherein the second processing device is configured to receive information regarding the control and the monitoring of the medical functions of the medical device from the first processing device;

wherein, when the first processing device has focus;

managing first communications between one or more user interface devices and the first processing device, and

permitting the one or more user interface devices to affect operation of the first processing device; and

wherein, when the second processing device has focus;

managing second communications between the one or more user interface devices and the second processing device, and

permitting the one or more user interface devices to affect operation of the second processing device; and

isolating the second processing device from the first processing device so that if the second processing device experiences a condition, the first processing device continues to control the medical functions and the medical functions of the medical device are not affected by the condition.

2. The method of claim 1, wherein the dialysis medical device further comprises the one or more user interface devices, the first processing device, and the second processing device.

3. The method of claim 1, further comprising:

receiving a request from the first processing device; and

switching focus from the second processing device to the first processing device responsively to the request;

wherein the request is based on monitoring of the medical device by the first processing device.

4. The method of claim 1, wherein switching focus comprises:

switching focus from the first processing device to the second processing device or from the second processing device to the first processing device responsively to a switch command received from one user interface device of the one or more user interface devices.

5. The method of claim 1, further comprising:

sending first and second protocol data to the first and second processing devices, respectively, so that the first and second processing devices are configured to maintain one or more respective connections with the one or more user interface devices, irrespective of which processing device of the first and second processing devices has focus.

6. The method of claim 1, wherein the condition comprises at least one of a shut down of the second processing device or a computer virus.

7. The method of claim 1, further comprising:

restarting the second processing device without affecting the first processing device and the medical functions of the medical device.

8. The method of claim 1, wherein the control of the medical device comprises operating at least one mechanical element

9. The method of claim 1, wherein the control of the medical device comprises operating at least one the following mechanical elements:

a pump configured to move blood from a patient to the medical device and back to the patient;

a pump configured to place minerals into a dialysate solution; and

a pump configured to provide water to the medical device.

10. One or more machine-readable media storing instructions for causing one or more user interface processing devices associated with a dialysis medical device to:

switch focus of one or more user interfaces from a first processing device to a second processing device or from the second processing device to the first processing device,

wherein the first processing device is configured to control and to monitor medical functions of the dialysis medical device, and wherein the second processing device is configured to receive information regarding the control and the monitoring of the medical functions of the medical device from the first processing device;

wherein, when the first processing device has focus;

manage first communications between one or more user interface devices and the first processing device, and

permit the one or more user interface devices to affect operation of the first processing device; and

wherein, when the second processing device has focus;

manage second communications between the one or more user interface devices and the second processing device, and

permit the one or more user interface devices to affect operation of the second processing device; and

isolating the second processing device from the first processing device so that if the second processing device experiences a condition, the first processing device continues to control and to monitor the medical functions and the medical functions of the dialysis medical device are not affected by the condition.

11. The one or more machine-readable media of claim 10, the instructions further comprising:

receiving a request from the first processing device; and

switching focus from the second processing device to the first processing device responsively to the request;

wherein the request is based on monitoring of the dialysis medical device by the first processing device.

12. The one or more machine-readable media of claim 10, the instructions to switch focus comprising:

switching focus from the first processing device to the second processing device or from the second processing device to the first processing device responsively to a switch command received from one user interface device of the one or more user interface devices.

13. The one or more machine-readable media of claim 10, the instructions further comprising:

sending first and second protocol data to the first and second processing devices, respectively, so that the first and second processing devices are configured to maintain one or more respective connections with the one or more user interface devices, irrespective of which processing device of the first and second processing devices has focus.

14. The one or more machine-readable media of claim 10, wherein the condition comprises at least one of a shut down of the second processing device or a computer virus.

15. The one or more machine-readable media of claim 10, the instructions further comprising:

restarting the second processing device without affecting the first processing device and the medical functions of the dialysis medical device.

16. A medical device having a dialysis machine comprising:

a first processing device;

a second processing device;

memory configured to store instructions for execution; and

one or more user interface processing devices configured to execute the instructions, the instructions for causing the one or more user interface processing devices to;

switch focus of the one or more user interface devices from the first processing device to the second processing device or from the second processing device to the first processing device,

wherein the first processing device is configured to control and to monitor medical functions of the medical, and wherein the second processing device is configured to receive information regarding the control and the monitoring of the medical functions of the dialysis medical device from the first processing device;

wherein, when the first processing device has focus;

manage first communications between the one or more user interface devices and the first processing device, and

permit the one or more user interface devices to affect operation of the first processing device; and

wherein, when the second processing device has focus;

manage second communications between the one or more user interface devices and the second processing device, and

permit the one or more user interface devices to affect operation of the second processing device; and

isolate the second processing device from the first processing device so that if the second processing device experiences a condition, the first processing device continues to control the medical functions and the medical functions of the dialysis medical device are not affected by the condition.
