  • Method for filling a medical packaging, filling device, and medical packaging formed as a pouch
    Patent number: 11548665
    Abstract: The invention relates to a method and to a device for filling a medical packaging formed as a pouch. Preferably, the packaging is filled with liquid via a port, wherein the port is aerated with a protective gas, such as nitrogen, for example, during filling According to the invention, prior to filling with liquid, the packaging is filled with an inert gas, such as nitrogen, for example, which then provides the headspace of the filled and closed pouch. This results in a particularly low oxygen content in the headspace of the pouch.

  • Contour-forming welding tool for pulse welding and contour-forming pulse welding method for a medical pack formed as a bag
    Patent number: 11498284
    Abstract: The invention relates to a welding tool and to a method for pulse welding of plastic films for medical packs formed as bags. In general, the invention provides that the film material which is plastified during welding and thus free-flowing is specifically displaced into a deepened, edge-side inner region of the sealing surface by increasing the sealing surface area. The film material accumulated in the recess leads to an increase in the film thickness in the inner region (25i) of the weld seam (6, 7, 8). As a result, the mechanical stability of the medical pack formed as a bag can be improved.
