Abstract: A conventional wound covering bandage, which completely covers the wound area in an airtight, is provided with at least one opening located over the wound area, on which a stack of layers is provided, which comprises at least a filter disk, at least one paper-like disk which allows vapor diffusion but is water-impermeable, and at least one further flexible film, likewise having an opening, the flexible film and the bandage being superposed with respect to one another and the opening in the flexible film being in registry with the opening in the bandage. The flexible film covers and seals off all the aforementioned stack of layers by adhering to a face of the water-impermeable disk and a border area on a face of bandage circumscribing the stack of layers. The water-impermeable disk seals off the layer stack on the side facing the outside air.

Abstract: This invention relates to a device for collecting and releasing saliva. The purpose of the invention is to provide sample device which is easy and safe to handle and which is configured as a disposable construction for use especially on medical diagnostics. To this end, the device consists of a porous unit which can take up the sample fluid and can be squeezed out. The unit is located inside a container which is sealed on one side at one end, and is arranged in such a way that it can be displaced out of said container at the other end which can be opened. The end of the container which can be opened is provided with a sealing cap.

Abstract: In the method for producing components (2) with a beveled cut edge (Y bevel), a vertical laser beam (5) is used to make at least one vertical cut through the material (1), parts (3) of the material (1) which lie outside the component (2) are removed, and then an inclined laser beam (6) is used to make an inclined cut along the vertical cut edge produced.

Abstract: In the method for producing components with a beveled cut edge (Y bevel), a plasma torch is used to make a vertical cut through a preferably flat material and then a laser beam is used to make an inclined cut along the cut edge produced.

Abstract: A one-piece dispensing device for the contamination-free administration of medicaments (cytostatica) is particularly suitable for use in ambulant treatment. The invention provides a connector for connecting medicament (cytostatica) containers to instruments by which the medicaments are administered. The connector is designed to prevent, without a complex apparatus, contamination of the surroundings during connection of the container and until its disposal. The dispensing device has at least one coupling member to create a non-releasable connection with a medicaments container. The coupling member has an insertion pin and barbed surfaces to accommodate the medicaments container. The coupling member is non-releasably connected via a tube to a flexible container which is to be filled with gas. The flexible container is non-releasably connected to a further tube outlet and a mechanically actuated stop valve is incorporated in each of the connecting tubes.
