Abstract

An apparatus for treating sleep disordered breathing may include: a flow generator to deliver a supply of air at positive pressure to a patient; a user interface, the user interface comprising: a display configured to display a plurality of screens; and a set of controls; and a controller in communication with the user interface and configured to control operation of the flow generator, wherein the flow generator is configured to couple with at least one accessory device and during a first mode of operation of the flow generator the controller determines a first screen of the plurality of screens to display on the display based on the at least one accessory device, the first screen of the plurality of screens being configured to enable adjustment of one or more parameters related to the operation of the at least one accessory device or the flow generator using the set of controls.

Claims

1. An apparatus for treating sleep disordered breathing comprising:

a flow generator configured to deliver a supply of air at positive pressure to a patient and couple with at least one accessory device;

a user interface, the user interface comprising;

a display configured to display a plurality of screens; and

a set of controls configured to receive user input; and

a controller in communication with the user interface, the controller configured to control operation of the flow generator and detect the presence or absence of at least one accessory device,

wherein during a first mode of operation of the flow generator the controller is configured to determine a first screen of the plurality of screens to display on the display in response to detection of the presence or absence of the at least one accessory device,

wherein if the controller detects the absence of the at least one accessory device, the first screen of the plurality of screens is a flow generator default screen that is configured to enable adjustment of a flow generator operational parameter that is associated with operation of the flow generator using the set of controls, and

wherein if the controller detects the presence of the at least one accessory device, the first screen of the plurality of screens is a screen that is configured to enable adjustment of an accessory device operational parameter that is associated with operation of the at least one accessory device using the set of controls.

2. The apparatus according to claim 1, wherein the flow generator operational parameter is a set treatment pressure or a ramp time.

3. The apparatus according to claim 1, wherein the at least one accessory device includes at least one of a humidifier and a heated tube.

4. The apparatus according to claim 1, wherein the at least one accessory device is a humidifier and the accessory device operational parameter is a humidity parameter of the humidifier.

5. The apparatus according to claim 1, wherein the at least one accessory device is a heated tube and the accessory device operational parameter is a heated tube temperature parameter.

6. The apparatus according to claim 1, wherein the at least one accessory device is a humidifier and a heated tube and the accessory device operational parameter is a climate control parameter.

7. The apparatus according to claim 1, wherein the first mode of operation is a run mode where the flow generator is delivering the supply of air at positive pressure to the patient.

8. The apparatus according to claim 1, wherein the flow generator is operable in a plurality of different modes and different screens of the plurality of screens are displayed in each of the different modes.

9. The apparatus according to claim 1, wherein the set of controls comprises at least a first control and a second control, and

wherein, when the display is displaying the first screen of the plurality of screens, the flow generator operational parameter or the accessory device operational parameter is adjustable in response to user interaction with the first control, and the display is configured to display a second screen of the plurality of screens in response to user interaction with the second control.

10. The apparatus according to claim 9, wherein, when the second screen is displayed on the display and a period of time has elapsed following cessation of user interaction with the set of controls, the first screen is displayed by replacing the second screen on the display.

11. The apparatus according to claim 1, wherein the user interface further includes a backlight configured to indicate different states of the flow generator.

12. The apparatus according to claim 11, wherein the state of the flow generator is indicated by changes in a color of the backlight.

13. The apparatus according to claim 12, wherein the color of the backlight includes at least one of blue, orange, or green.

14. The apparatus according to claim 12, wherein the change to the backlight occurs over a predetermined time period.

15. The apparatus according to claim 14, wherein the predetermined time period is 3 seconds.

16. The apparatus according to claim 11, wherein the state of the flow generator is indicated by changing brightness of the backlight.

17. The apparatus according to claim 11, wherein the backlight flashes intermittently on and off to indicate an error state.

18. The apparatus according to claim 1, wherein the set of controls is located on the flow generator.

19. The apparatus according to claim 1, wherein the set of controls comprises at least one of a dial and a button.
