9. A housing in accordance with claim 8 , wherein an upper edge of the inner wall of the mounting groove is higher than a lower edge of the two collars of the cover.

10. A housing in accordance with claim 9 , wherein the cover lies on an upper edge of the inner wall of the mounting groove.

11. A housing in accordance with claim 1 , wherein the mounting groove has a rounded profile with an inner radius.

12. A housing in accordance with claim 11 , wherein the inner radii of the mounting groove are greater than 3 mm.

13. A housing in accordance with claim 1 , wherein the depth of the mounting groove is greater than 5 mm and its width is greater than 10 mm.

14. A medical device housing, which medical device is to be protected against penetration of liquids, the medical device housing comprising:

a housing wall with an opening having an edge area comprising a mounting groove;

another housing wall arranged opposite said housing wall, at least said housing wall and said another housing wall defining said mounting groove, said housing wall and said another housing wall terminating at an end of said mounting groove that drains liquid;

a removable cover closing the opening in a cover closed position, the cover having an outer edge area comprising an outer edge surface and a collar which protrudes downwards when the cover is in the cover closed position and having a drip edge at a bottom of the collar when the cover is in the cover closed position, such that a liquid dripping from the drip edge falls into the mounting groove, wherein the cover has another collar to provide two collars arranged at a distance to one another, each collar protruding downwards into the mounting groove, said collar being arranged between said outer edge surface and said another collar.

15. A medical device housing in accordance with claim 14 , wherein:

a gap is formed between an outside of one of the collar and said another collar and the another housing wall, said gap having a gap width, at which an adherence of liquid is prevented as a result of capillary forces;

said collar is located between said another collar and one of said housing wall and said another housing wall when the cover is in the cover closed position, said another collar being located between said collar and another one of said housing wall and said another housing wall when the cover is in the cover closed position; and

said collar extends parallel to said another collar.

16. A medical device housing in accordance with claim 15 , wherein the gap has a gap width of about 2 mm.

17. A medical device housing in accordance with claim 14 , wherein the mounting groove has a liquid volume capacity of more than 200 mL, whereby less than 200 mL of liquid will not reach the medical device in an interior of the housing, said collar being located adjacent to said one of said housing wall and said another housing wall when the cover is in the cover closed position, said another collar being located adjacent to said another one of said housing wall and said another housing wall when the cover is in the cover closed position.

18. A medical device housing in accordance with claim 14 , wherein the inner radii or inner radius of the mounting groove are or is greater than 5 mm.

19. A device housing for devices with at least one module, which is to be protected against penetration of liquids, the device housing comprising:

a housing with a top side opening having an edge area comprising a mounting groove, said housing comprising a first housing wall, a second housing wall and a housing portion extending between said first housing wall and said second housing wall, said first housing wall defining said top side opening, said first wall, said second wall and said housing portion defining said mounting groove;
