1, high permeability membrane is selected, and the end of the catheter is fixed in S-shape and U-shape.
2. The adhesive tape is first fixed horizontally on the slat (small plane), half on the transparent adhesive tape and half on the patient's skin. The second adhesive tape is folded back into a butterfly shape at the seam wing, fixed on the transparent adhesive film, and horizontally attached above it with adhesive tape, half attached to the transparent adhesive tape and half attached to the patient's skin. Heparin cap can be completely wrapped with gauze and fixed with adhesive tape if the tube holder does not need infusion within one week. Record the date and time on the tape and sign it.
3. When filming, it should be torn reversely to prevent the catheter from coming out due to tearing forward.
4. Don't stick the transparent film on the tail of the catheter.
5. Tips to prevent the adhesive film from curling and loosening: In the process of tube placement, because the outside of PICC catheter is usually fixed on the needle wing and needle eye by disposable transparent application, and the extension catheter and heparin cap are fixed by adhesive tape, in the process of long-term retention and use, the application will curl and loosen, and even the PICC tube will fall off, which brings a lot of inconvenience to the tube placement. In order to prevent the adhesive film from loosening, after each tube placement and maintenance, a pair of stockings with a length of about 10cm can be cut and put on the outer layer of the adhesive film, which can not only fix the adhesive film, but also prevent the adhesive film from loosening, without affecting the patient's blood circulation, which is very convenient and practical.
