摘要:
The technical problem of avoiding the contamination of liquids by valve elements, in particular the contamination of medicaments within medical devices, and facilitating the production of devices comprising valve elements is solved by an apparatus comprising a first part (300) comprising a sealing structure (302, 304), a membrane (308) being attached to said first part and a second part (310) being attached to said membrane, wherein said second part comprises a valve area (312) with a first opening (326) and a second opening (320), wherein said valve area is located in the area of said sealing structure, wherein said valve area is configured to allow for a fluidic communication between said first opening and said second opening and wherein said sealing structure is configured to allow for an interruption of said fluidic communication between said first opening and said second opening. The technical problem is also solve by a method for producing a valve element, comprising the steps of injection moulding a first part comprising sealing structure, producing a second part and said second part comprising a valve area with a first opening and a second opening attaching a membrane to said second part via agent-free joining techniques and attaching said first part to said membrane, wherein said valve area is located in the area of said sealing structure, wherein said valve area is configured to allow for a fluidic communication between said first opening and said second opening and wherein said sealing structure is configured to allow for an interruption of said fluidic communication between said first opening and said second opening.Selon la présente invention, le problème technique dévitement de la contamination de liquides par des éléments de vanne, en particulier la contamination de médicaments dans des dispositifs médicaux, et facilitant la production de dispositifs comprenant des éléments de vanne est résolu par un appareil comprenant une première partie (300) compr
