Abstract

A ventilator with memory for operating data has a control unit for a breathing gas source. The operating data memory is provided to store the current changeable operating data. The control unit is provided with a data-saving function which stores the current operating parameters during an intermission in the operation of the device. The control unit also has a memory readout function, by which the stored operating data can be read out after the end of an intermission to allow the ventilator to resume operation in correspondence with the saved operating data.

Claims

1. A ventilator with memory for operating data, the ventilator comprising a control unit for a breathing gas source, wherein the operating data memory is adapted to store the current changeable operating data, and the control unit is provided with a data-saving function, which stores the current operating parameters during an intermission in the operation of the device, and a memory read-out function, for reading out the stored operating data after the end of the intermission such that the ventilator resumes operation in correspondence with any saved operating data.

2. The ventilator according to claim 1, comprising means for activating the data-saving function an operating problem occurs.

3. The ventilator according to claim 1, characterized in that the data-saving function is activated when a pause function is actuated manually.

4. The ventilator according to claim 1, wherein at least one pause mode is provided.

5. The ventilator according to claim 1, wherein a pause mode can be preselected by the user.

6. The ventilator according to claim 1, wherein a pause mode can be initiated automatically by the unit upon recognition of predefined events.

7. The ventilator according to claim 1, wherein, during pause mode, the user can speak and/or sneeze and/or drink and/or eat and/or exchange kisses and/or cough and/or telephone and/or read and/or take medications with essentially no interference from the ventilator.

8. The ventilator according to claim 1, wherein, during pause mode, the ventilator provides the user with a breathing gas pressure which is lower than the original pressure.

9. The ventilator according to claim 1, wherein, during pause mode, the ventilator provides the user with a breathing gas pressure of less than 6 mbars.

10. The ventilator according to claim 1, wherein, during pause mode, the ventilator provides the user with a breathing gas pressure of less than 4 mbars.

11. The ventilator according to claim 1, wherein, during pause mode, the ventilator provides the user with a breathing gas pressure of less than 2 mbars.

12. The ventilator according to claim 1, wherein, during pause mode, the ventilator provides the user with a breathing gas pressure of essentially 0 mbar.

13. The ventilator according to claim 1, wherein the pause function can be initiated by remote control.

14. The ventilator according to claim 1, comprising the pause function can be initiated by a pause button (13) located in the area of a wristband (29) for initiating the pause function.

15. The ventilator according to claim 1, comprising the pause function can be initiated by a pause button (13) located in the area of a clip for initiating the pause function.

16. The ventilator according to claim 1, wherein the pause function can be activated for a preselected period of time.

17. The ventilator according to claim 1, comprising an analyzer is provided for the automatic detection of the termination of a pause state.

18. The ventilator according to claim 1, wherein a microphone is connected to the analyzer for the detection of events.

19. The ventilator according to claim 1, wherein the analyzer is connected to a memory in which sound patterns are stored.

20. The ventilator according to claim 1, wherein the pause function can be deactivated for a preselected period of time.

21. A method for controlling a ventilator, comprising preselecting a pause mode by making use of at least one selection means.

23. A method according to claim 21, comprising activating pause mode automatically on the basis of the detection of an event.

24. A method according to claim 21, wherein a user activates the pause mode.

25. A method according to claim 21, wherein a user activates the pause mode by actuating a means provided in the area of the ventilator.

26. A method according to claim 21, wherein a user activates the pause mode by actuating a means connected to the ventilator by a cable.

27. A method according to claim 21, wherein a user activates the pause mode by actuating a means which communicates with the ventilator in wireless fashion.

28. A method according to claim 21, wherein at least one event is detected by a microphone.

29. A method according to claim 21, wherein a detected sound is compared with a stored sound pattern.

30. A method according to claim 21, wherein the pause mode can be deactivated under preselected conditions.

22. A method for controlling a ventilator, comprising hardware for automatically activating pause mode in response to events by means of at least one selection circuit.

31. Means which communicates wirelessly with a ventilator, wherein a user activates the pause mode of the ventilator by making contact with the means.
