  • Patent number: 11903609
    Abstract: An insertion site for a cannula (23) on a skin (8) of a patient is prepared by applying a skin cover unit (1) of the type comprising a window (2) and a wall (3) in extension of the window (2) and connected to the window (2) by a bending region (4) for bending the wall (3) into an angled orientation relatively to the window (2); wherein the win-dow (2) comprises a stabilizing frame (5) and an ultrasonic-transparent flexible sheet (6) within the frame (5). The flexible sheet (6) is glued onto the skin (8) of the patient for ultrasonic investigation of the insertion site through the flexible sheet (6). By bending the bending region (4), the angular orientation of the wall (3) is adjusted into an approximately perpendicular orientation relatively to the window (2) for separating the insertion site from the flexible sheet (6) by the wall (3).

  • Patent number: 11833775
    Abstract: A flexible bag comprising a first wall and a second wall superposed over the first wall, the walls being connected to each other along their longitudinal edges by two gussets. As per a bag formation process, successively: the bag is closed with a flap extending from one of the walls and held on the other wall to form a closed end of the bag; the first wall of the bag is gripped at a predetermined distance from the closed end with the lower grippers and the second wall by the upper grippers and the walls are separated to form a side on the gussets; the second wall is released by the upper grippers and the closed end is folded by a folding device on to the second wall, thus making the bottom.
