[0002] At present, circular compression method is mostly used to stop bleeding at the fistula puncture point of hemodialysis in China, that is, fistula puncture bandage plus dressing and cotton ball circumferential ligation of the arm for compression and hemostasis. Because the fistula puncture bandage is circumferentially tied to the arm to obtain greater compression force, it is tied relatively tightly, which not only affects the activity of the patient's forearm, but also affects the venous blood return. Generally, after a few minutes, the patient will feel swelling in the extremities, or even purple and numbness, which affects the blood circulation of the entire arm. During circumferential ligation, the impact force of blood flow on the blood vessel wall is relatively large, which is not conducive to the attachment of platelet factors, and the hemostasis time is relatively prolonged. Long-term use will cause fistula complications, and the fistula puncture bandage and dressing have poor waterproof performance. When exposed to water or splashed with water, it will penetrate into the dressing and easily cause infection to the puncture point. Utility Model Content
