Patent ID: 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). The cover unit (1) in or at the bending region (4) comprises a stabilizer (9) that is configured for maintaining the angled orientation between the wall (3) and the window (2) by a stabilizing action of the stabilizer (9).
