[0002] Arteriovenous fistula is a surgery before dialysis. It connects the artery and vein through surgery so that the vein can better handle the amount of blood returning to the body, which is helpful for dialysis. During the compression of the arteriovenous fistula, the elastic bandage is directly fixed on the needle-eye gauze and compressed. First tighten and then loosen. After five to ten minutes, loosen the bandage appropriately, first loosen the vein end and then the arterial end. After 15 to 20 minutes, observe the puncture point. If there is no bleeding, loosen the elastic bandage a little more. If there is no bleeding, remove the elastic bandage.

[0003] The inner wall of the elastic bandage is fixed by the fleecy side and the hook side of the Velcro. When loosening the bandage, the fleecy side needs to be turned up to release the fixation of the elastic bandage, and then the two sides of the bandage need to be adjusted and loosened.
