Abstract

A user interface for a portable oxygen concentration system. The user interface includes a touch screen and a controller coupled to the touch screen. The controller is configured to detect when a first portion of the touch screen is contacted by a user, and thereafter operate the touch screen for displaying an icon on a second portion of the touch screen.

Claims

1. A user interface for operating a portable oxygen concentrator that includes a power supply and for deactivating the portable medical device, comprising:

a touch screen; and

a controller coupled to the touch screen, the controller configured to

(a) display a first icon in an initial location on the touch screen,

(b) detect a user touching the first icon,

(c) display a second icon on the touch screen after the user has touched the first icon, wherein the second icon is displayed in a different location than the initial location, regardless of where on the touch screen the first icon has been displayed,

(d) detect a user touching the second icon, and

(e) deactivate the portable oxygen concentrator responsive to detection of the second icon being touched by suspending a supply of power from the power supply to the portable oxygen concentrator.

2. The user interface of claim 1, wherein the controller comprises a timer, and wherein the controller is configured for resetting the touch screen if the second icon on the touch screen is not touched within a predetermined time after detection of the user touching the first icon.

3. The user interface of claim 1, wherein the first icon comprises a symbol, and wherein the second icon comprises a power interface button.

4. The user interface of claim 1, wherein the first icon is a power interface button.

5. The user interface of claim 1, wherein the first icon is a virtual power button.

6. The user interface of claim 3, wherein the symbol represents a power button.

7. The user interface of claim 4, wherein the second icon is a second power interface button.

8. The user interface of claim 5, wherein the second icon is a second virtual power button.

9. The user interface of claim 6, wherein the second icon is larger than the first icon.

10. A method for operating an oxygen concentrator that includes a power supply and for deactivating the oxygen concentrator, comprising:

(a) displaying a first icon in an initial location on a touch screen;

(b) detecting a user touching the first icon;

(c) displaying a second icon on the touch screen after the user has touched the first icon, wherein the second icon is displayed in a different location than the initial location, regardless of where on the touch screen the first icon has been displayed;

(d) detecting a user touching the second icon; and

(e) deactivating the oxygen concentrator responsive to detection of the second icon being touched by suspending a supply of power from the power supply to the oxygen concentrator.

11. The method of claim 10, wherein the first icon represents a power button.

12. The method of claim 10, wherein the first icon includes a symbol that represents a power button, and wherein the second icon includes the symbol.

13. The method of claim 10, wherein the first icon is a power interface button.

14. The method of claim 10, wherein the first icon is a virtual power button.

15. The method of claim 13, wherein the second icon is a second power interface button.

16. The method of claim 12, wherein the second icon is larger than the first icon.

17. The method of claim 14, wherein the second icon is a second virtual power button.

18. A user interface for operating a portable oxygen concentrator, comprising:

a touch screen; and

a controller coupled to the touch screen, the controller configured to

(a) display a first power button in an initial location on the touch screen,

(b) detect a user touching the first power button,

(c) display a second power button on the touch screen after the user has touched the first power button, wherein the second power button is displayed in a different location than the initial location, regardless of where on the touch screen the first power button has been displayed,

(d) detect a user touching the second power button, and

(e) deactivate the portable oxygen concentrator responsive to detection of the second power button being touched by suspending the supply of power from the power supply to the portable oxygen concentrator.
