Abstract: A system for treating and/or preventing a viral, bacterial and/or fungal infection in the oral cavity and/or along the respiratory tract, in particular the interior of the nose, throat, trachea and/or lungs, of a patient by reactive species generated by plasma as well as a plasma for such use is disclosed. The system comprises a plasma source generating reactive species in a gas, the plasma source being configured to be located outside a body of the patient, and a species directing member forming at least one duct for guiding at least a part of the reactive species generated by the plasma source into the oral cavity and/or the respiratory tract.

Abstract: An explosive powder charge operated setting tool includes a housing (1) with a bolt guide (2) projecting axially outwardly from its leading end in the setting direction. The bolt guide (2) is axially displaceably relative to the housing. A magazine (5) for fastening elements (6) is mounted on the bolt guide (2) and is displaceable relative to the bolt guide counter to the setting direction against the force of a first spring (11) positioned between the bolt guide and the magazine. A second spring (13) is located between the housing (1) and the magazine (5) and has a maximum force in the setting direction and a spring travel each greater than the spring force and travel of the first spring (11).
