PICC also inevitably has some complications such as local bleeding, hematoma, phlebitis, etc. How to effectively prevent and treat local bleeding without influencing the use of a catheter, and a unified and effective tool is not available at present. As is well known, the scientific, reasonable and effective compression bandaging method for the puncture part is a key technology for preventing and reducing the local bleeding. The post-operation hemostasis method of the PICC is actively researched in all hospitals, and a hemostasis bandage made of a thumb, an oval double-faced convex stone or a cloth buckle with the diameter of 2.5cm is reported to achieve a certain effect when used for hemostasis after needle withdrawing in venipuncture, but the double-faced convex stone or the cloth buckle has the possibility of damaging a catheter. Wulin uses buttons, gauze blocks and 3 kinds of hemostatic tourniquet belts in the application of 3 kinds of arteriovenous internal fistula hemostatic tourniquet belts to perform hemostatic nursing on arteriovenous internal fistula puncture points, and finds that the internal fistula complication of the gauze rolling-finger tourniquet belt is the least, but the needle eye bleeding rate reaches 1.9%, and complete hemostasis cannot be realized.
