[0002] Peripherally inserted central catheter (PICC) is a catheter that is inserted into a vein in the arm. The catheter goes directly to the large vein close to the heart, avoiding direct contact between the drug and the arm vein. The blood flow in the large vein is very fast, which can quickly dilute the drug and prevent it from irritating the blood vessels.
[0003] After being discharged from the hospital, the child needs to take the PICC tube home to recuperate. It is easy for the dressing to get wet and the puncture site to get infected during bathing, which will affect the child's recovery and quality of life. The PICC catheter fixing sleeve on the market can be put on the elbow to prevent the PICC dressing from being soaked by water during bathing and causing puncture site infection. However, the existing fixing sleeve has a relatively complex structure and cannot seal the elbow and its surroundings as a whole, and the waterproof effect is poor.
