Abstract

The disclosed device serves for artificial respiration and has a blower connected to a control. The blower is held by a supporting part, which assumes the task of decoupling and other functions. The blower and the supporting part are arranged in a blower box. Both the control and the blower box are arranged in a housing. The control is connected to at least one indicating device and also to at least one operating element.

Claims

1. A device for artificial respiration, wherein the device comprises a blower connected to a control, both the control and the blower being arranged in a housing, and the control being connected to at least one indicating device and at least one operating element, and wherein the blower is secured in the housing by a viscoelastic or elastomeric supporting part.

2. The device of claim 1, wherein the housing comprises or consists of a front unit, which comprises the indicating device, and two further housing parts, which form a blower box.

3. The device of claim 1, wherein the supporting part is secured between two housing parts, the two housing parts respectively having associated chamber halves of a high-pressure region and an intake region.

4. The device of claim 1, wherein the supporting part is arranged in a vertical direction between housing parts.

5. The device of claim 1, wherein the supporting part forms a first seal, which provides a seal with respect to sealing surfaces of housing parts, and forms a second seal, which provides a seal with respect to sealing surfaces of the two housing parts and thus pneumatically separates a high-pressure region from an intake region.

6. The device of claim 1, wherein the supporting part in a blower box serves for redirecting the, and consequently reducing noise, and for this purpose comprises at least two openings.

7. The device of claim 1, wherein the supporting part comprises at least one opening that is surrounded at least in certain portions by a collar.

8. The device of claim 1, wherein at least three redirecting features are arranged within a blower box for a flow of respiratory gas.

9. The device of claim 1, wherein at least one sound-damping element is arranged within a blower box and/or on the supporting part.

10. The device of claim 1, wherein the indicating device and also a front sheet that has at least one operating element are accommodated in a front unit.

11. The device of claim 1, wherein an indicating device is arranged in an inclined manner in relation to a vertical direction.

12. The device of claim 1, wherein the housing has a triangular cross-sectional area.

13. The device of claim 1, wherein a front unit comprises or consists of a vertically extending first segment and a second segment, which is inclined in relation to a vertical direction and in which an indicating device is arranged.

14. The device of claim 1, wherein the indicating device is formed as a panel-like display, which is fixed in a front unit by a frame-like securing element.

15. The device of claim 1, wherein a securing element provides a clasp for fixing the display or can be screwed in a front unit.

16. The device of claim 1, wherein only one mechanical operating element is provided for activation of a device function.

17. The device of claim 16, wherein, in addition to the only one mechanical operating element, further operating areas are provided on the display formed as a touchscreen.

18. The device of claim 1, wherein a line routing for connecting a pressure measurement comprising a line portion of a first diameter and a line portion of a second diameter is formed within the device, the second diameter being smaller than the first diameter.
