Abstract

A ventilator with integrated breathing air humidifier has at least two defined air pathways provided in the breathing air humidifier, wherein the breathing air humidifier is installed and fixed on a horizontal surface of the ventilator. The ventilator with integratable breathing air humidifier has a breathing air humidifier with at least a top part and a bottom part, wherein a water reservoir is provided in the bottom part, and wherein the top part cannot be removed from the bottom part when the unit is in at least one operating mode. The ventilator may have an air humidifier with at least one water reservoir, and at least one filing device for the water reservoir in the breathing air humidifier, wherein the filing device can be operated with one hand and/or opened with one hand.

Claims

1. A ventilator with integratable breathing air humidifier, comprising:

at least two defined air pathways provided in a region of the breathing air humidifier, and at least one blower mounted in the ventilator by elastomeric elements.

2. The ventilator according to claim 1, wherein a the sound-damping box is provided in the ventilator.

3. The ventilator according to claim 1, wherein the at least one blower is fastened in place in the ventilator by suspension from above.

4. The ventilator according to claim 1, wherein, in a housing of the ventilator, a receptacle is provided into which at least part of the breathing air humidifier is insertable, and which has at least one connecting element for a functional connection of the breathing air humidifier to the ventilator.

5. The ventilator according to claim 1, wherein the blower is installed in a sound-damping box positioned inside a housing of the ventilator and supported elastically with respect to the ventilator housing, wherein the sound-damping box is semi-enclosed.

6. The ventilator according to claim 1, with a breathing gas blower, which is supported elastically, wherein the elastic support is comprised of at least one pin made of elastomeric material, which has a retaining profile, into which a mating profile of the blower engages.

7. The ventilator according to claim 1, wherein the ventilator has a pressure-measuring connection located downstream of the breathing air humidifier.

8. The ventilator according to claim 1, comprising a dummy element for replacing the breathing air humidifier, wherein the ventilator has a pressure measurement connection located in an outlet area of the dummy element.

9. The ventilator according to claim 1, comprising a bottom part and a top part, wherein the top part has an external contour such that, after the top part and the bottom part have been assembled and installed so that the ventilator is operational, the components cannot be separated from each other.

10. The ventilator according to claim 1, further comprising a pressure sensor mounted on a control circuit board of the ventilator and connected to a measurement site through a pressure measurement line.

11. The ventilator according to claim 1, comprising an air intake, wherein the air intake is located in a rear area of the ventilator and provided with a cover cap, configured to serve both as an appearance panel and as a sound-damping element.

12. The ventilator according to claim 1, wherein the ventilator has an interior space enclosed by an equipment housing, wherein at least one structural element is mounted on a sound-damping support, wherein the sound-damping support has at least one opening, and wherein at least one marking corresponding to the opening is provided on a mounting surface provided for the sound-damping element.

13. The ventilator according to claim 2, wherein the sound-damping box has at least two vertical planes, where at least one of the planes is subjected to gas of a higher pressure.

14. The ventilator according to claim 4, comprising vertical, flow-carrying elements, which are located in a center of a humidifying chamber to prevent or to reduce an intrusion of water into the unit and/or into a patient hose if the unit tips.

15. The ventilator according to claim 1, wherein the humidifier is held in place by at least one connecting element in an area of the ventilator and the connecting element also serves to attach a hose.

16. The ventilator according to claim 1, in which a ventilating hose is connected to the ventilator by at least one connecting element, wherein the connecting element has a hose area, which is connectable to the hose, and a unit area, which is connectable to the ventilator.

17. The ventilator according to claim 1, having an opening for a connecting element for rapid, one-handed connection of a ventilator hose to the ventilator by the connecting element, wherein the connecting element has a hose area, which is connectable to the hose, where, via actuation of an operating element, a functional part of the connecting element is locked and/or unlocked in an opening in the ventilator, and thus the connecting element, with hose connected, is attached or detached from the ventilator.

18. The ventilator according to claim 1, wherein the breathing air humidifier has a water tank and a filling port, which can be closed by a stopper, wherein the stopper has a retaining element attached to the water tank, a sealing element pivotably connected to the retaining element and pivotable between an open position and a closed position, and wherein the sealing element is spring-loaded toward the open position with respect to the retaining element.

19. The ventilator according to claim 18, wherein a breathing gas inlet line and a breathing gas outlet line are each located in a lower area of the unit on essentially the same level.

20. The ventilator according to claim 2, wherein the sound-damping box has a space in a plane for a centrally located blower receptacle, where the space extends along at least one additional air-conducting plane, in which it forms fluidic constrictions which contribute to sound-damping.
