Abstract

A gas-tight sealing device (10) encloses at least one part of a coupling element (12) as well as at least one section of a line element (14) connected to the coupling element (12). The the gas-tight sealing device (10) comprises a sealing device portion or wall (11) that adjoins a first sealing point and a second sealing point (16, 18). The sealing device portion or wall (11) extends around, in a gas-tight manner, the line element (14) and the coupling element (12) or a wall (20), or a further line element, in or at which the coupling element (12). The gas-tight sealing device (10) encloses a volume defined by the geometry of the sealing device portion (11) in a gas-tight manner between the first sealing point (16) and the second sealing point (16, 18).

First claim

What is claimed is:

1. A medical device comprising:
a wall;
a coupling element mounted to the wall and configured as a gas removal point;
a line element connected to the coupling element; and
a gas-tight sealing device, wherein at least one part of the coupling element as well as at least one section of the line element are enclosed in a gas-tight manner by the gas-tight sealing device, the sealing device comprising:
a sealing device portion, which encloses at least one part of the coupling element as well as at least one section of the line element connected to the coupling element;
a first sealing point, the sealing device portion adjoining the first sealing point and extending around the line element at the first sealing point; and
a second sealing point, the sealing device portion adjoining the second sealing point and extending around the coupling element, said second sealing point being connected to the wall in a gas tight manner, whereby the sealing device portion encloses a volume defined by a geometry of the sealing device portion between the first sealing point and the second sealing point.

2. A medical device in accordance with claim 1 , wherein the sealing device portion, the first sealing point and the second sealing point are formed as one piece from a material acting as a seal at edges defined by the first sealing point and the second sealing point.

3. A medical device in accordance with claim 1 , further comprising a vent port formed in the sealing device portion between the first sealing point and the second sealing point, said vent port being configured to connect to a vent line.

4. A medical device in accordance with claim 1 , wherein the enclosed volume of the sealing device portion encloses no additional components aside from the coupling element or the part of the coupling element and the section of the line element.

5. A medical device in accordance with claim 1 , wherein:
the gas-tight sealing device is configured to flow off gas from a leaky connection of the line element to the coupling element.

6. A medical device in accordance with claim 1 , wherein:
the gas-tight sealing device is configured to collect gas escaping between the line element and the coupling element.

7. A medical device in accordance with claim 1 , wherein:
the second sealing point is connected to a first side of the wall in a gas tight manner;
the wall and the coupling element define a gap between the wall and the coupling element, the sealing device being configured to flow off gas discharged from a leaky connection of the line element with the coupling element, the discharged gas flowing from the first side of the wall to a second side of the wall.

8. A medical device in accordance with claim 1 , wherein:
the wall has a gas area and an electrical area;
the coupling element is mounted in the gas area of the wall.

9. A medical device in accordance with claim 1 , further comprising:
a medical supply device, the wall being part of the medical supply device;
the coupling element being a gas removal point of the medical supply device.

10. A medical device in accordance with claim 9 , wherein:
the medical supply device provides a combustible gas stream to the gas removal point;
the coupling element passes on an arriving gas stream from the medical supply device;
the line element passes on the gas stream from the coupling element.

11. A medical device comprising:
a wall;
a coupling element mounted to the wall and configured as a gas removal point;
a line element connected to the coupling element;
a sealing device wall encloses at least one part of the coupling element as well as at least one section of the line element connected to the coupling element;
a sealing edge, the sealing device wall adjoining the sealing edge and gas-tight extending around the line element at the sealing edge; and
a further sealing edge connected to the wall, the sealing device wall adjoining the further sealing edge and gas-tight extending around the further sealing edge, whereby the sealing device wall encloses a volume defined by a geometry of the sealing device wall between the sealing edge and the further sealing edge in a gas-tight manner, the volume including at least one part of the coupling element as well as at least one section of the line element.

12. A medical device in accordance with claim 11 , wherein the sealing edge and the further sealing edge comprise seals.

13. A medical device in accordance with claim 11 , wherein the sealing edge and the further sealing edge comprise bonded edges of the sealing device wall.

14. A medical device in accordance with claim 11 , wherein sealing device wall, the sealing edge and the further sealing edge are formed as one piece from a material acting as a seal at edges defined by the sealing edge and the further sealing edge.

15. A medical device in accordance with claim 11 , further comprising a vent port formed in the sealing device wall between the sealing edge and the further sealing edge, said vent port being configured to connect to a vent line.

16. A medical device in accordance with claim 11 , wherein the enclosed volume of the sealing device wall encloses no additional components aside from the coupling element or the part of the coupling element and the section of the line element.

17. A medical device in accordance with claim 11 , wherein:
the sealing device wall is configured to flow off gas from a leaky connection of the line element to the coupling element.

18. A medical device in accordance with claim 11 , wherein:
the second sealing point is connected to a first side of the wall in a gas tight manner;
the wall and the coupling element define a gap between the wall and the coupling element, the sealing device wall being configured to flow off gas discharged from a leaky connection of the line element with the coupling element, the discharged gas flowing from the first side of the wall to a second side of the wall.

19. A medical device comprising:
a wall;
a coupling element mounted in said wall, and configured as a gas removal point to pass on a gas stream from the wall;
a line element connected to said coupling element and configured to pass on the gas stream from said coupling element;
a sealing device having a first sealing edge surrounding, and connected to, said line element in a gas-tight manner, said sealing device having a second sealing edge surrounding said coupling element, said second sealing edge being connected to one of said wall and said coupling element in a gas tight manner, said second sealing edge being connected to said wall in a gas tight manner;
said wall and said coupling element defining a gap between said wall and said coupling element, said sealing device being configured to flow off gas discharged from a leaky connection of said line element with said coupling element, the discharged gas flowing from a first side of said wall to a second side of said wall.

20. A medical device in accordance with claim 19 , further comprising:
