Abstract

The invention relates to a device for operating a breathing apparatus with a touch-sensitive graphical display and just one other mechanical operating element, wherein the basic treatment can be started by pressing down the mechanical operating element, and additional adjustments are made using the touch-sensitive graphical display.

Claims

1. An operating device for a breathing apparatus, wherein the device comprises a touch-sensitive graphical display which at least occasionally represents a range of values for a ventilation parameter and numerically displays at least individual values, and a memory for ventilation parameter values, and further comprises

at least one data point associated with the range of values,

at least one position on the touch-sensitive graphical display which is associated with the data point using switching logic,

a switching logic which, when the position on the touch-sensitive graphical display which is associated with the data point using switching logic is touched,

causes at least one numerical value associated with the data point and/or a confirmation field for a numerical value to be displayed,

a switching logic which, when the numerical value or the confirmation field is touched, applies this numerical value to an associated respiratory gas parameter and writes this numerical value, together with the associated respiratory gas parameter, to the memory.

2. The device of claim 1, wherein the ventilation parameter is the pressure or flow or volume or frequency or IPAP or EPAP or PEEP or FiO2.

3. The device of claim 1, wherein the operating field is in the form of a number line or bar and an entire range of values is visualized on the display in the form of a number line or bar, the visualized number line being also in the form of an operating field.

4. The device of claim 1, wherein the operating field is touch-sensitive over an entire visualized adjustment range.

5. The device of claim 1, wherein a desired value can be selected by merely touching a desired range.

6. The device of claim 1, wherein a detected value is visualized in an additional field.

7. The device of claim 6, wherein the detected value is additionally available for fine adjustment using the symbols +/−

.

8. The device of claim 1, wherein the memory stores at least a value used and input last and a value used and input chronologically before said value and the memory always outputs the chronologically most recent value first if an undo function is actuated.

9. The device of claim 1, wherein at least one collection of ventilation parameters stored in the memory in a retrievable manner comprises at least three preset parameters selected from pressure or flow or volume or frequency or IPAP or EPAP or PEEP or FiO2, and a region in which a collection of ventilation parameters is graphically represented is provided for this collection of ventilation parameters in a region of the touch-sensitive graphical display, and the device further comprises

at least one data point associated with the collection of ventilation parameters,

at least one position on the touch-sensitive graphical display which is associated with the data point using switching logic,

switching logic which, when the position on the touch-sensitive graphical display which is associated with the data point using switching logic is touched,

causes at least one collection of ventilation parameters associated with the data point and/or a confirmation field for the collection of ventilation parameters to be displayed,

a switching logic which, when the numerical value or the collection of ventilation parameters is touched, uses this collection of ventilation parameters.

10. The device of claim 1, wherein the device further comprises a graphical adjustment aid for at least one ramp gradient.

11. The device of claim 1, wherein the device further comprises a graphical adjustment aid for trigger sensitivity is provided.

12. The device of claim 1, wherein at least one adjustment element is in the form of a dial.

13. The device of claim 1, wherein at least one circular display element is present.

14. The device of claim 1, wherein a rotary pushbutton is present.

15. The device of claim 1, wherein a start/stop area is present.

16. The device of claim 15, wherein the start/stop operating area is arranged in a region of the touchscreen and/or can be generated in different forms by an apparatus controller.

17. The device of claim 1, wherein individual values of a ventilation parameter are numerically displayed and a selected value is also numerically displayed and the selected ventilation parameter is graphically visualized.

18. The device of claim 1, wherein three fixed levels are provided for the ventilation parameter and these levels can be adjusted using the symbols +/−

to thereby fine-tune the ventilation parameter on a patient-specific basis.

19. The device of claim 1, wherein the device comprises a graphical display element instead of a touch-sensitive display element and the graphical display element comprises a separate mechanical operating element, adjustments made using the mechanical operating element being graphically visualized on the graphical display element.

20. The device of claim 19, wherein a change in values during an adjustment process using the mechanical operating element and/or a selected value and/or an available range of values is visualized on the graphical display element.

21. An operating device for a breathing apparatus, wherein the device comprises:

(a) a graphical display which at least occasionally represents a range of values for a ventilation parameter and numerically displays at least individual values, and a memory for breathing parameter values,

and further comprises

(b) at least one data point associated with the range of values, at least one position on the graphical display which is associated with the data point using switching logic,

(c) a switching logic which, when a position of a mechanical operating element assigned to the data point using switching logic is actuated,

(d) causes at least one numerical value assigned to the data point and/or a confirmation field for the numerical value to be displayed,

(e) a switching logic which, when the position of the mechanical operating element assigned to the data point using switching logic is actuated, applies this numerical value to an associated respiratory gas parameter and writes this numerical value, together with the associated respiratory gas parameter, to the memory.
