HOCHFREQUENZSCHWEISSELEKTRODE FÜR MEDIZINISCH GENUTZTE MEHRFACHKAMMERBEUTEL AUS EINER KUNSTSTOFFFOLIE UND AUS DIESEM MATERIAL HERGESTELLTE BEUTEL

摘要

The object of the present invention is a radiofrequency welding electrode for multicompartment plastic film bags for medical use, and the bags produced with this equipment. According to this method, the multicompartment bags (1) are produced by joining two suitable flexible plastic films by radiofrequency welding with electrodes bearing specially shaped, raised indentations for producing exceptionally wide welded parts (16) without beads of excess material at the points where the weld lines cross the sealing area between compartments (2, 3, 4). The invention concerns the production of bags particularly intended for use in medical perfusion, and including at least two compartments containing products that should be mixed only at the time of use.
