Claim 6:
7. A method for preparing an insertion site for a cannula or other puncture device (23) on a skin (8) of a patient, the method comprising providing a skin cover unit (1) comprising a window (2) and a wall (3), the window comprising a stabilizing frame (5) and the wall (3) being provided in extension of the window (2) and connected to the window (2) by a bending region (4) for bending the bending region so that the wall (3) gets into an angled orientation relative to the window (2); wherein the window (2) comprises an adhesive layer (7) on a first side of the window (2) for gluing the window (2) onto the skin (8) of the patient; wherein the window (2) comprises an ultrasonic-transparent flexible sheet (6) for ultrasonic investigation of the patient through the flexible sheet; wherein the method comprises gluing the first side of the window (2) onto the skin (8) of the patient and, before or after the gluing, bending the bending region (4) for changing the angled orientation of the wall (3) into an angle in the range of 45-135 degrees relatively relative to the window (2) and applying an ultrasonic probe (19) to the second side of the window (2) and ultrasonic-imaging the insertion site (20) for controlled insertion of the cannula or other puncture device (23) into the patient; wherein the skin cover unit (1) comprises a stabilizer (9), wherein the stabilizer (9) is provided in or at the bending region (4) and is configured for maintaining the angled orientation between the wall (3) and the window (2) by a stabilizing action of the stabilizer (9), wherein the method comprising, by the stabilizer (9) maintaining the angled orientation of the wall (3) relative to the window (2) in order for the wall (3) to separate the insertion site (20) from the window (2), wherein the stabilizer (9) is a bendable sheet comprising two legs, where each leg crosses the bending region and is fastened to the wall side of the frame and to the window side of the frame, wherein the method comprises bending the wall (3) relative to the window (2) at the bending region (4) into an angled orientation between the wall (3) and the window (2).
