Abstract: An adhesive joining device for providing and/or producing an adhesive connection in an adhesive point and/or adhesive section on a metal surface (5) to a body and/or component (4) to be adhered thereon and an adhesive using an electrochemical etching device, having a vacuum holder (1) with a vacuum connection (11), wherein a vacuum can be formed between the adhesive joining device and the metal surface (5) around the adhesive point and/or adhesive section to be produced; a tool changing holder (2) which receives at least two different tools (31, 32) in a time-staggered manner and in a defined position; a first usable tool (31) which can be inserted into the tool holder (2) in a time-staggered manner, namely an electrochemical etching cell for an electrolyte with an etching chamber which is oriented towards the metal surface (5), a feed for supplying an electrolyte (311) to the etching chamber, a drain for the etching chamber (312), and two electrodes (12, 313) with corresponding electric contacts, one electro

Abstract: A filling needle can be used in a tube set for transferring a flowable medium, in particular a pharmaceutical product. The filling needle has a needle end for temporary insertion in a filling vessel. Furthermore, the filling needle has a connector end for connecting the filling needle to a filling vessel, via which the medium can be supplied to the filling needle. An inner tube lumen of the filling needle is defined by an inner tube layer made of silicone. The result is a filling needle that can be manufactured inexpensively.

Abstract: A multi-component plastic body designed as a multi-layered tube has at least one silicone component and at least one further polymer component made of a further nonpolar polymer. A bonding agent between the silicone component and the further polymer component has bonding bodies which mechanically bond the two components to one another. For the production of such a multi-component plastic body, first a base component is produced. The bonding agent is applied thereto, and subsequently a cover component is applied to the base component, such that the bonding agent comes to lie between the silicone component and the further polymer component. The result is a multi-component plastic body having a secure bond between the at least one silicone component and the at least one further polymer component.
