Torsion springs two are fixedly connected between the outer sides of both ends of the rotating shaft two and the inner wall of the housing two.
[0011] Preferably, magnets are fixedly connected to the ends of the two fixing bracelets II far from the moving bracelet, and the two magnets adsorb each other to form a ring to bind on the patient's arm.
[0012] The technical effects and advantages of the present utility model: By using the moving bracelet to drive the comparison strip to be pulled out from the inside of the starting box, and then using the scale sizes formed by the multiple constant-width long slots on the comparison strip, it can be clearly understood how long the distance is between the previous puncture position and the current puncture position. And because the constant-width long slots are provided as through holes, direct puncture can be carried out. Then, the position of the moving bracelet is fixed by the fixing bracelet II and the magnet on the moving bracelet, which is convenient for a medical staff to operate without the need for a second person, saving labor and being convenient for operation. When long-term fixation for puncture is required, position marking can also be carried out by using the through-hole setting of the constant-width long slots, which is convenient for operation after the present utility model is removed. The whole process can avoid the harm caused to the patient by the repeated puncture positions in the climbing-style puncture, and can also be operated by a single person, saving time and effort.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] The present utility model provides an arteriovenous fistula ladder puncture scale as shown in the figure, which includes a first fixed bracelet 1. A starting point box 2 is arranged on the first fixed bracelet 1. A comparison strip 3 pulled out from the inside of the starting point box 2 is arranged on one side of the starting point box 2. The other end of the comparison strip 3 is fixedly provided with a moving bracelet 5. Equally spaced and clearly spaced fixed-width long grooves 4 are machined on the comparison strip 3.
[0020] A telescopic component is arranged inside the starting point box 2, and one end of the comparison strip 3 is connected to the telescopic component.
[0021] The first fixed bracelet 1 includes elastic metal sheets 102 elastically bound on the patient's hand, and a flannel wrapping layer 101 is wrapped outside the two elastic metal sheets 102.
[0022] Specifically, the telescopic component includes a first rotating shaft 10 movably arranged inside the starting point box 2 through a bearing. One end of the comparison strip 3 is wound and connected to the first rotating shaft 10. Partition plates 11 are fixedly connected to both ends of the first rotating shaft 10 and outside the comparison strip 3. A first torsion spring 8 is fixedly arranged between the partition plates 11 and the inner wall of the starting point box 2.
[0023] Specifically, the comparison strip 3 is made of a transparent material.
[0024] Specifically, the moving bracelet 5 includes a second shell 502 fixedly connected to the other end of the comparison strip 3. Binding components that can extend out of the outside of the moving bracelet 5 and are fixedly bound to the patient's arm are arranged on both sides inside the second shell 502.
[0025] Specifically, the binding component includes a second rotating shaft 503 arranged inside the second shell 502 through a bearing. A second fixed bracelet 6 is wound and connected to the outside of the second rotating shaft 503. A second torsion spring 501 is fixedly connected between the outer sides of both ends of the second rotating shaft 503 and the inner wall of the second shell 502.
[0026] Specifically, magnets 7 are fixedly connected to one ends of the two second fixed bracelets 6 away from the moving bracelet 5, and the two magnets 7 adsorb each other to form a ring-shaped binding on the patient's arm.
[0027] Working principle: When using the present utility model, the fixed bracelet 1 in the present utility model is bound to the patient's arm, and then clamped at the previous puncture position or the bend of the wrist that is easy to identify. Then, the movable bracelet 5 is pulled, and the movable bracelet 5 drives the comparison strip 3 to be pulled out from the inside of the starting box 2. Then, by using the scale sizes formed by the plurality of constant-width long slots 4 on the comparison strip 3, it can be clearly understood how long the distance is between the previous puncture position and the current puncture position. And because the constant-width long slots 4 are through holes, direct puncture can be carried out. Then, the fixed bracelet 2 6 and the magnet 7 on the movable bracelet 5 are used to fix the position of the movable bracelet 5, which is convenient for the medical staff to operate alone without the need for a second person, saving labor and being convenient for operation. Then, when long-term fixation for puncture is required, the through-hole setting of the constant-width long slots 4 can also be used for position marking, which is convenient for operation after the present utility model is removed. The whole process can avoid the harm caused to the patient by the repeated puncture positions in the form of climbing stairs, and can also be operated by one person, saving time and effort.
