Abstract

A ventilator device (10) includes a display screen (50, 101) to display a plurality of ventilator functions/modes (or menus) and a plurality of parameters (or sub-menus) associated with at least one of said ventilator functions/modes. A control member, e.g., in the form of a multifunction finger-operable dial (55, 102) is provided to select from the plurality of ventilator functions/modes and/or parameters, the dial being manipulatable in a first manner (e.g., rotation) to scroll between said parameters, and being manipulatable in a second manner (e.g., touching, pressing and/or depressing) to select one of the ventilator functions/modes and/or parameters.

Claims

1. A ventilator device comprising:

a display screen to display a plurality of ventilator functions/modes and a plurality of parameters associated with at least one of said ventilator functions/modes; and

a finger-operable dial to select from the plurality of ventilator functions/modes and parameters, the dial being manipulatable in a first manner to scroll between said parameters, and being manipulatable in a second manner to select one of the parameters.

2. The ventilator device as claimed in claim 1, wherein the first manner of manipulation of the dial includes rotation of the dial.

3. The ventilator device as claimed in claim 1, wherein the second manner of manipulation of the dial includes touching, pressing, and/or depression of the dial.

4. The ventilator device as claimed in claim 1, wherein the dial is scrollable to a desired ventilator function/mode, at which time the dial is depressed whereupon the display screen is caused to display the parameters associated with the desired ventilator function/mode.

5. The ventilator device as claimed in claim 1, wherein the dial is scrollable in the second manner to scroll to a desired parameter after which the dial is depressed whereupon the parameter associated with the desired ventilator function/mode is selected.

6. The ventilator device as claimed in claim 1, wherein the dial is structured to provide tactile and/or visual feedback to the user when a setting has been altered.

7. The ventilator device as claimed in claim 1, wherein the ventilator functions/modes relate to one of more of the following:

humidification settings, including climate control level, heated tube temperature and/or humidity; and

/or flow generator settings including pressure, ramp time, ventilation type, patient type, patient weight and/or treatment mode.

8. The ventilator device as claimed in claim 7, wherein the parameters associated with ventilation type include invasive and non-invasive.

9. The ventilator device as claimed in claim 7, wherein the parameters associated with patient type include adult and child.

10. The ventilator device as claimed in claim 7, wherein the parameters associated with treatment mode include PSV, ASV and PACV.

11. The ventilator device as claimed in claim 1, wherein the ventilator device includes a housing and the dial is operable in a first configuration in which the dial is retracted either partially or fully in the housing, and a second configuration in which the dial protrudes outward from a surface of the housing.

12. The ventilator device as claimed in claim 11, wherein the dial has multiple extension levels in the second configuration.

13. The ventilator device as claimed in claim 11, wherein the ventilator device is locked when the dial is in the first configuration.

14. The ventilator device as claimed in claim 1, wherein the dial is associated with a biasing mechanism to bias the dial in an extended position.

15. The ventilator device as claimed in claim 14, wherein the biasing mechanism includes a spring.

16. The ventilator device as claimed in claim 1, further comprising a blower to deliver pressurized gas in the range of 2-30 cm H₂O.

17. The ventilator device as claimed in claim 16, wherein the blower is contained within a housing having an inlet and an outlet, the outlet being configured to be connected to a gas delivery tube that delivers the pressurized gas to the patient via a patient interface.

18. A method to control a ventilator device comprising:

displaying a plurality of ventilator functions/modes and a plurality of parameters associated with at least one of said ventilator functions/modes; and

using a single finger-operable dial, selecting from the plurality of ventilator functions/modes and parameters, the dial being manipulated in a first manner to scroll between said parameters, and being manipulated in a second manner to select one of the parameters.

19. The method as claimed in claim 18, wherein the first manner of manipulation of the dial includes rotation of the dial.

20. The method as claimed in claim 18, wherein the second manner of manipulation of the dial includes touching, pressing and/or depression of the dial.

21. The method as claimed in claim 18, wherein the ventilator functions/modes relate to one of more of the following:

ventilation type, patient type, patient weight and/or treatment mode.

22. The method as claimed in claim 21, wherein the parameters associated with ventilation type include invasive and non-invasive.

23. The method as claimed in claim 21, wherein the parameters associated with patient type include adult and child.

24. The method as claimed in claim 21, wherein the parameters associated with treatment mode include PSV, ASV and PACV.

25. The method as claimed in claim 18, further comprising a blower to deliver pressurized gas in the range of 2-30 cm H₂O.

26. The method as claimed in claim 25, wherein the blower includes a housing having an inlet and an outlet, the outlet being configured to be connected to a gas delivery tube that delivers the pressurized gas to the patient via a patient interface.

27. A ventilator device comprising:

a blower to generate pressurized gas in a pressure range suitable for treatment of a breathing disorder; and

a user interface having a display screen to display at least one menu and a submenu including a plurality of parameters associated with said menu, and a multifunction control member operable in a first manner to scroll between said parameters and in a second manner, different from the first manner, to select one or more of the parameters.

28. The ventilator device as claimed in claim 27, wherein the first manner of operation of the control member includes rotation of the control member.

29. The ventilator device as claimed in claim 27, wherein the second manner of operation of the control member includes touching, pressing, and/or depression of the control member.

30. The ventilator device as claimed in claim 27, wherein the control member comprises a dial.

31. The ventilator device as claimed in claim 30, wherein the dial is rotatable and when the dial is turned relatively slowly, a parameter is adjusted in minimal increments per encoder increment, and when the dial is turned relatively quickly, the parameter will be adjusted in larger or whole number increments per encoder increment.
