Abstract: The present invention relates to a coupling assembly such as a coupling assembly for coupling an ostomy bag to a base plate, said base plate being adhered around a stoma. The present invention especially relates to a coupling assembly comprising a first, second and third coupling part, which are coupled together to form a coupling assembly.

Abstract: A method for welding together two layers or workpieces within a multi-layer assembly in which laser light is directed through an outer layer of the assembly, allowing transmission of the laser light from its outer surface to at least within the vicinity of its inner surface substantially without any absorption of energy from the laser light. The laser light is directed towards a layer having an absorbent component, corresponding to a portion thereof, capable of absorbing laser light within a given wavelength range thereby creating a welded area between a surface of the layer having the absorbent component and a surface of a layer facing the layer having the absorbent component. The absorbent component can be provided either within the bulk of a layer or it can be provided as a separate surface layer on one or both surfaces of a layer.

Abstract: An ostomy body side mounting wafer and a method of preparing the ostomy body side mounting wafer, where the wafer is assembled from two parts using laser welding. The laser light is provided through one of the parts having a low or lower absorption of the laser light. The other part has a higher absorption of the laser light, whereby the interface between the two parts is heated at the welding zone(s) of the laser light. In this manner, an assembly is obtained independently of the thicknesses of the materials and even close to openings or other edges.

Abstract: A method of decreasing the penetration depth of radiation provided to an interface, such as a surface, or a predetermined volume in a means, where the means has a scattering coefficient larger than one tenth of an absorption coefficient thereof so that the radiation not absorbed at the interface or in the volume but transmitted further into the means is at least partly reflected toward the interface/volume. The radiation intensity is higher in the volume and the absorption coefficient may be reduced while retaining the total absorption in the volume. This may be used for all known techniques where radiation is desired absorbed, such as in welding, surface preparation, polymer chemistry, the activation of photo activatable substances etc.

Abstract: The present invention relates to a method for welding together two layers (1, 3), or work-pieces, within a multi-layer assembly (1, 2, 3). The present invention provides a method in which laser light (4) is directed through an outer layer (1) of the assembly, allowing transmission of the laser light from its outer surface to at least within the vicinity of its inner surface substantially without any absorption of energy from the laser light, towards a layer (3) comprising an absorbent component (7), corresponding to a portion thereof, capable of absorbing laser light within a given wavelength range thereby creating a welded area (6) between a surface of the layer (3) comprising the absorbent component (7) and a surface of a layer (1) facing the layer (3) comprising the absorbent component (7). The absorbent component (7) can be provided either within the bulk of a layer or it can be provided as a separate surface-layer on one or both surfaces of a layer.
