Abstract

The invention refers to a new type of ventilator, which has a compact block, in which rigid pipes and a gas supply container are integrated. The new structure is more compact than conventional superstructures. In addition to this improvements have been made to the therapy gas delivery and nebulization.

Claims

1. A ventilator, excluding anaesthetizing equipment, comprising:

a closed breathing circuit, comprising;

a housing with an interior,

a compact block made of plastic,

a gas storage integrated in the block,

at least one ventilator connection,

at least one compressed air connection,

at least one valve,

at least one control system for the at least one valve,

a ventilating tube,

at least one connection for the ventilating tube,

gas pipes in the interior of the housing that connect the gas supply container with the at least one valve and the ventilator gas connection and the ventilator tube connection,

wherein the majority of the gas pipes are rigid pipes and are integrated in the block together with the gas supply container, and

wherein the at least one valve and the at least one connection for the ventilating tube and the ventilator gas connection are integrated in the block.

2. The ventilator according to claim 1, further comprising a compressed gas pipe, and a compressor having an output within the housing, which compressor is connected to the gas storage directly or indirectly via the compressed gas pipe.

3. The ventilator according to claim 2, wherein the compressor is connected to the gas storage by a tube.

4. The ventilator according to claim 2, further comprising at least one heated gas deliverer on the compact block that is heated via compressor waste heat.

5. The ventilator according to claim 4, wherein the gas deliverer comprises at least one of a pipe of at least 100 mm in length within a wall of the gas storage and a tube of at least 100 mm in length that protrudes into the gas storage.

6. The ventilator according to claim 1, further comprising a compressor, wherein the at least one control system comprises a set of electronics that, on an electrical side, permits at least three different modes of operation, either separately or combined.

7. The ventilator according to claim 6, in which the modes of operation comprise at least one of an AC connection to an external power supply, a DC connection to a DC supply or an external battery, and a battery or accumulator connection to an internal battery.

8. The ventilator according to claim 1, wherein on a gas delivery side, the ventilator permits at least three different modes of operation, either separately or combined.

9. The ventilator according to claim 8, wherein the different modes of operation comprise at least one of an external compressed air supply or a compressed air bottle;

a compressed air connection via an integrated compressor;

a ventilation gas connection to an external ventilation gas supply or to an external ventilation gas bottle; and

a therapy gas connection to an external therapy gas bottle.

10. The ventilator according to claim 1, wherein parallel to a ventilation gas or compressed gas deliverer, a therapy gas deliverer is provided via at least one rigid pipe that is separated from other gas deliverers.

11. The ventilator according to claim 10, wherein the therapy gas deliverer is adjustable using the same electronics as the ventilation gas or compressed gas deliverer and the rigid pipe is integrated in the block.

12. The ventilator according to claim 10, wherein the therapy gas deliverer delivers therapy gas and has at least one electronically controlled therapy gas valve via which therapy gas is measured through the ventilating tube proportional to patient gas flow, and wherein the therapy gas is only mixed with the patient gas flow in close proximity to the patient.

13. The ventilator according to claim 1, further comprising, an electrical control system,

wherein an internal power supply is assigned to the electrical control system and the compressor within the housing, and

wherein the input of the power supply is connected to the output of at least one integrated charging equipment that permits input of at least two different types of power feed.

14. The ventilator according to claim 13, wherein the internal power supply comprises an accumulator or a battery.

15. The ventilator according to claim 13, wherein an input of the charging equipment is connected to a manipulation and interrupt-free AC source with a voltage or voltage range of between 80 and 270 volts.

16. The ventilator according to claim 13, wherein an input connection is provided for connection to a DC power supply.

17. The ventilator according to claim 15, wherein an input connection is provided for connection to a DC power supply.

18. The ventilator according to claim 1, wherein the block has least one integrated sensor fox device control.

19. The ventilator according to claim 1, wherein the at least one control system comprises software that is programmed via a control panel and allows setting sigh ventilation for a patient at a selected time interval and a selected sigh volume.

20. The ventilator according to claim 12, wherein the therapy gas uses its own therapy gas output.

21. The ventilator according to claim 20, wherein the sigh ventilation is set for a selected sigh ventilation pressure.

22. The ventilator according to claim 1, further comprising a nebulizer connection or a nebulizer pipe,

wherein the control system comprises software that is programmed via a control panel that, during, operation, controls a nebulization function via the nebulizer pipe and via at least one program-controlled nebulizer valve in such a way that nebulization can be set at certain intervals and a duration can be set during nebulization.

23. The ventilator according to claim 22, wherein nebulization depends upon the patient'"'"'s inspiratory dynamics.

25. A ventilator according to claim 19, wherein parallel to the ventilation gas or compressed gas deliverer, a therapy gas deliverer is provided via at least one rigid pipe that is separated from other gas deliverers.

26. The ventilator according to claim 25, wherein the therapy gas deliverer is adjustable using the same electronics as the ventilation gas or compressed gas deliverer, and

wherein the rigid pipe is integrated in the block.

27. The ventilator according to claim 26, wherein the therapy gas uses its own therapy gas input.

28. The ventilator according to claim 25, wherein the therapy gas delivery has at least one electronically controlled therapy gas valve via which therapy gas is measured through the ventilation tube proportional to patient gas flow, and wherein the therapy gas is only mixed with the patient gas flow in close proximity to the patient.

29. The ventilator according to claim 6, wherein the modes of operation are command free and continuously interchangeable.

30. The ventilator according to claim 8, wherein the modes of operation are command free and continuously interchangeable.

24. A ventilator comprising:

gas pipes, gas storage, a compressor, electrical or electronic control systems, and

a battery,

all of which are integrated in one block,

wherein the ventilator further comprises emergency backup features that ensure ventilation continues when at least one of an external electrical or pneumatic supply from the compressor fails.
