Abstract

A device with a respirator (1) and with a humidifier (11) for breathing gas. Breathing gas humidification is adapted to the different operating states of the respirator (1). A connection (13) is provided for bidirectional data transmission between the control and operating unit (8) of the respirator (1) and the control and operating unit (9) of the humidifier (11).

Claims

1. A respiration device comprising:

a respirator;

a humidifier for humidifying breathing gas;

a first operating and control unit for controlling operation of said respirator;

a second control and operating unit at said humidifier; and

a connection means for providing data transmission between said first operating and control unit and said second control and operating unit.

2. A device in accordance with claim 1, wherein said connection means has additional means for transmitting electric energy.

3. A device in accordance with claim 1, wherein said data transmission includes said first operating and control unit transferring data to said second control and operating unit via said connection means including inspiratory gas flow data, inspiratory oxygen concentration data, inspiratory gas temperature data and a mode of operation of said respirator data.

4. A device in accordance with claim 1, wherein said respirator includes means for operating said humidifier as well as for displaying and outputting status and alarm reports of said humidifier.

5. A respiration device comprising:

a breathing gas inspiration line;

a breathing gas expiration line;

a respirator with a breathing flow control for regulating a breathing gas inspiration pressure and a breathing gas expiration pressure;

a humidifier for humidifying breathing gas fed to said inspiration line;

a first operating and control unit for controlling operation of said respirator including setting breathing gas inspiration pressure and breathing gas expiration pressure;

a second control and operating unit for adapting breathing gas humidification to different operating states of the respirator based on respiration data; and

a connection means providing respiration data transmission between said first operating and control unit and said second control and operating unit.

6. A device in accordance with claim 5, wherein said connection means has additional means for transmitting electric energy.

7. A device in accordance with claim 6, further comprising:

a gas flow sensor for measuring inspiration breathing gas flow;

an oxygen sensor for measuring inspiratory oxygen concentration; and

a temperature sensor for measuring inspiratory breathing gas temperature, wherein said data transmission includes said first operating and control unit transferring data to said second control and operating unit via said connection means including inspiratory gas flow data, inspiratory oxygen concentration data, inspiratory gas temperature data and a mode of operation of said respirator data.

8. A device in accordance with claim 5, wherein said respirator includes means for operating said humidifier as well as for displaying and outputting status and alarm reports of said humidifier.

9. A respiration device comprising:

a breathing gas inspiration line;

a breathing gas expiration line;

a respirator with a breathing flow control valve for regulating a breathing gas inspiration pressure and a positive end expiratory pressure valve for regulating breathing gas expiration pressure;

a humidifier for humidifying inspiration breathing gas;

a first operating and control unit for controlling operation of said respirator including controlling said breathing flow control valve and controlling said positive end expiratory pressure valve;

a second control and operating unit for adapting breathing gas humidification to different operating states of the respirator; and

a connection means for providing respiration data transmission between said first operating and control unit and said second control and operating unit.

10. A device in accordance with claim 9, wherein said connection means has additional means for transmitting electric energy.

11. A device in accordance with claim 9, further comprising:

a gas flow sensor for measuring inspiration breathing gas flow;

an oxygen sensor for measuring inspiratory oxygen concentration; and

a temperature sensor for measuring inspiratory breathing gas temperature, wherein said data transmission includes said first operating and control unit transferring data to said second control and operating unit via said connection means including inspiratory gas flow data, inspiratory oxygen concentration data, inspiratory gas temperature data and a mode of operation of said respirator data.

12. A device in accordance with claim 9, wherein said respirator includes means for operating said humidifier as well as for displaying and outputting status and alarm reports of said humidifier.

13. A device in accordance with claim 9, further comprising:

a gas supply connected to said breathing flow control valve; and

a blower connected to said breathing flow control valve wherein said first operating and control unit controls a mode of operation of said respirator based on a blower operation with said blower, operation with said gas supply and combinations of blower operation and operation with gas supply wherein said data transmission includes respirator mode of operation data.

14. A device in accordance with claim 13, wherein said blower draws breathing gas from the environment via a filter in case of the blower operation and breathing gas is taken from a central gas supply unit in case of operation with said gas supply whereby when gas is taken from the environment, the breathing gas already has a certain moisture content, so that the humidifier output can be reduced, whereas dry gases are to be humidified when the gas is taken from the central gas supply unit.
