Abstract: A liquid-accommodating container (8) for a device (2) providing vacuum for medical applications, in particular for the vacuum treatment of wounds in a human or animal body. The container (8) has two half-shell parts (20, 22), which are permanently joined to each other and bound the interior of the container in the joined state. A filter (100) lies against an inner region (106) of the half-shell part (22) facing away from a first housing part (4) on one side and against a sealing element (54) on the other side under axial stress in an axial direction (102). The sealing element (54) is attached to the half-shell part (20) facing the first housing part (4), wherein the axial stress is formed by the joining of the half-shell parts (20, 22) and associated deformation of the sealing element (54) by the filter (100).

Abstract: The invention relates to a fastening device for a negative-pressure therapy appliance, in particular for negative-pressure treatment of wounds on the human or animal body, comprising a holding means, a hollow body and a receiving area.

Abstract: A lumbar support with an archable supporting element (1-3) is proposed, wherein for the individual adjustment of the curvature of the archable supporting element (1-3) to the needs of the individual user, an adjustment mechanism (8-17) is provided, which is configured in such a manner that it can bring about both a curvature of the archable supporting element (1-3) into a first curvature direction, in which the archable supporting element (1-3) forms a convex supporting surface, and a curvature of the archable supporting element (1-3) into a second curvature direction, in which the archable supporting element (1-3) forms a concave supporting surface.

Abstract: An operation microscope includes an illuminating device and an interference filter in the illuminating beam of the illuminating device. The interference filter is suitable for incorporation into the operation microscope. In order to prevent the yellow tinge that is present in long-known UV interference filters, the interference layer applied directly to the carrier substrate is a layer between 8 and 12 nm thick of yttrium fluoride, thorium fluoride, lanthanum fluoride or cerium fluoride.
