Abstract: For the radiation-proof elution and metering of a radioactive nuclide from a nuclide generator into a stock ampoule, the generator located in a radiation-proof housing is connected, on the one hand, to a stock of liquid nuclide solvent and, on the other hand, to an aspiration and metering device, connected to a filling mechanism, for the eluate.

Abstract: An arrangement for applying a tissue adhesive on the basis of human or animal proteins for seamlessly or seam-supportingly connecting human or animal tissue or organ parts, sealing wounds, stopping bleedings and the like, which tissue adhesive is formed in situ by bringing together solutions of the proteins and of clot-promoting coagulation factors, includes a holding device for a plurality of syringe bodies ending in coni. In order to achieve a reliable mixing of the tissue adhesive components by single-hand operation with a premature hardening of the components prior to reaching the laceration site being prevented, the coni of the individual syringe bodies are connected by a collecting head having separated conveying channels for the components of the tissue adhesive emerging from the coni. A common actuating device is provided for the plungers of all syringe bodies.
