Abstract

A user interface for respiratory apparatus comprises a combination of a menu display (302), push buttons (304, 308, 310) and a rotary control dial (306). The user interface may include a menu control for detecting at least one parameter from the user'"'"'s operation of the controls to navigate the menu and applying this to subsequent operation of the user interface controls. The user parameter may be a direction of operation of the rotary control dial which the user associates with a particular direction of navigation within the menu.

Claims

1. A control interface for a device which includes a rotary control dial, including:

a display for displaying a device control menu;

a rotary control dial for operation by a user to navigate within the menu;

a menu control which causes entry to the control menu to occur at a known position in the menu, which determines from operation of the control dial by the user in navigation of the menu at least one user parameter, and applies the determined user parameter to subsequent operation of the control dial within that menu.

2. The control interface of claim 1 wherein the menu control applies the determined user parameter also to subsequent operation of the control dial by the user in other menus.

3. The control interface of claim 2 wherein the menu control applies the determined user parameter to subsequent operation of the control dial by the user within the same user session of the device.

4. The control interface of claim 1 wherein the user parameter comprises a direction in which the user turns the dial to navigate a direction in the menu.

5. The control interface of claim 4 wherein the menu control determines a rotary direction that the user initially turns the dial to a linear direction within the menu, and assigns that rotary direction to that linear direction.

6. The control interface of claim 1 wherein the device is a respiratory device.

7. The control interface of claim 6 wherein the respiratory device is a flow generator for treating sleep disordered breathing.

14. The set of controls of claim 1 wherein the display is a colour display.

8. Apparatus for treating sleep disordered breathing comprising

a flow generator for delivering a supply of breathable gas at positive pressure to a patient;

and

a control interface comprising;

a display for displaying a device control menu for the flow generator;

a rotary control dial for operation by a user to navigate within the menu;

a menu control which causes entry to the control menu to occur at a known position in the menu, which determines from operation of the control dial by the user in navigation of the menu at least one user parameter, and applies the determined user parameter to subsequent operation of the control dial within that menu.

9. The apparatus of claim 8 wherein the menu control applies the determined user parameter also to subsequent operation of the control dial by the user in other menus.

10. The apparatus of claim 9 wherein the menu control applies the determined user parameter to subsequent operation of the control dial by the user within the same user session of the device.

11. The apparatus of claim 8 wherein the user parameter comprises a direction in which the user turns the dial to navigate a direction in the menu.

12. The apparatus of claim 11 wherein the menu control determines a rotary direction that the user initially turns the dial to a linear direction within the menu, and assigns that rotary direction to that linear direction.

13. A set of controls for a CPAP device comprising:

a start/stop button;

a display;

two menu keys;

&

and a push-button dial.

15. A user interface for a respiratory device for the treatment of sleep disordered breathing comprising:

a set of controls as claimed in claim 13;

wherein at least one menu key is constructed and arranged so that during delivery of respiratory therapy activating said at least one key once causes the display of an alternative menu display and activating it a second time returns the display to its prior state.

16. Apparatus for treating sleep disordered breathing comprising

a flow generator for delivering a supply of air at positive pressure;

a humidifier;

a set of controls including a push-button dial whereby the push-button dial is programmed to alternatively adjust at least two parameters chosen from the set of;

a level of humidification, a treatment pressure, a ramp time, and a heated tube temperature.

17. The apparatus of claim 16 wherein the set of controls are located on the flow generator.

18. Apparatus for treating sleep disordered breathing comprising:

a device for delivering a supply of air at positive pressure;

a humidifier;

a set of controls including a dial, the dial being settable between at least two states, wherein during a first state, rotation of the dial adjusts the level of humidification wherein during a run mode of the apparatus, the dial automatically reverts to the first state following a period where there is no interaction with the set of controls.
