The hemodialysis puncture needle is a butterfly needle, and two needle handles positioned on two sides of the needle are arranged behind the needle. The hemodialysis puncture needle needs to be fixed, and the current common fixing mode is to use an adhesive tape for fixing, and the adhesive tape is stuck to the hemodialysis puncture needle and then stuck to the skin of a patient. However, some patients are allergic to the adhesive tape, some patients are dialyzed for a long time, the skin is vulnerable to repeated sticking and tearing of the adhesive tape, and the skin is easily damaged by continuing to stick the adhesive tape, so that a non-sticking mode is required to fix the hemodialysis puncture needle.

The internal fistula puncture needle fixing band is sleeved on the arm of a patient, a catheter of the hemodialysis puncture needle is clamped by the movable clamping plate and the box body, and the clamping force is from the elasticity of the spring.
The force for fixing the hemodialysis puncture needle by the internal fistula puncture needle fixing belt is derived from friction force, namely the friction force for clamping the catheter by the movable clamping plate and the box body, and the force can prevent the hemodialysis puncture needle from sliding relative to the internal fistula puncture needle fixing belt; and secondly, the friction force between the internal fistula puncture needle fixing band and the arm is used for preventing the internal fistula puncture needle fixing band from sliding on the arm of a patient. The catheter of the hemodialysis puncture needle is flexible, and the catheter is thin, so that the friction force between the internal fistula puncture needle fixing band and the catheter cannot be large. The force of the internal fistula puncture needle fixing band for clamping the arm cannot be large, so that the blood flow of the arm is not influenced and the patient is uncomfortable, and therefore the friction force between the internal fistula puncture needle fixing band and the arm is limited. Therefore, the reliability of the fixation of the internal fistula puncture needle fixing band is not high.
