Description

Technical Field

[0001] The utility model relates to the technical field of arteriovenous fistula arm training belts, in particular to an arteriovenous fistula arm training belt. Background Art

[0002] Arteriovenous fistula is the safest and longest-lasting blood access for hemodialysis patients. Compared with other vascular pathways, it has fewer complications, a longer service life, can provide sufficient blood flow, and can withstand repeated punctures. It is currently the first choice for establishing long-term vascular pathways. Effectively maintaining the patency of arteriovenous fistulas and sufficient blood flow is directly related to the quality of hemodialysis patients. Actively implementing arteriovenous fistula function exercises is an effective and simple way to increase arteriovenous fistula blood flow, extend the service life of arteriovenous fistulas, and avoid arteriovenous fistula failure.

[0003] As is known, in clinical practice, when patients perform arteriovenous fistula exercises, they use a tourniquet to tie up their arms. Specifically, the tourniquet is tied 5 cm away from the armpit on the side of the fistula to block the return of peripheral venous blood, fill the blood vessels, and increase the tension at the fistula. Then, by clenching the fist, the blood flow rate in the blood vessels is increased, and the tension in the blood vessels is increased. Repeated fisting exercises cause arterial blood to be injected, which increases the pressure in the fistula. The venous wall is compressed, causing the proliferation of muscular fibroblasts and vascular smooth muscle cells in the blood vessels. Clenching the fist causes the blood vessels to passively expand, and loosening the fist causes the blood vessels to contract rapidly, which increases the elasticity of the blood vessels, thereby increasing the blood flow, allowing the veins to expand effectively, accelerating the maturation of the fistula, and causing the fistula blood vessels to reach the hemodialysis standard in a short period of time.

[0004] However, the use of a tourniquet requires the assistance of others, who need to intermittently loosen or tighten the tourniquet, which is cumbersome and inconvenient. In addition, a small number of medical staff use homemade buckles with Velcro to replace tourniquets, but the Velcro is prone to detachment due to repeated squeezing during exercise, affecting the exercise effect. Therefore, there is an urgent need for an exercise belt that is easy for one person to operate and can be tied stably. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide an arteriovenous fistula arm training belt.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is an arteriovenous fistula arm training belt: it includes a strap, a plurality of convex balls are provided on the front side of the strap, and the convex balls are evenly spaced along the direction of the strap; a rotatable square ring is provided at one end of the strap, and a cassette structure is provided at the other end of the square ring, and the cassette structure is provided with a belt hole and a clamping plate, the clamping plate is slidably connected to the cassette structure and can be inserted into the belt hole, and the clamping plate is elastically matched with the leaf spring in the cassette structure.

[0007] As an improvement, the clamping plate is provided with a T-shaped plate head, and the T-shaped plate head is located outside the clamping belt structure.

[0008] As an improvement, there are two leaf springs.

[0009] As an improvement, the square ring is made of metal.

[0010] As an improvement, a fixed gasket is provided on the back of one end of the binding strap, and the gasket is located on the back of the square ring.

[0011] As an improvement, the convex ball is fixedly connected to the binding strap.

[0012] The utility model has the advantages over the prior art in that: the T-shaped plate head is pulled outward, the strap head is inserted into the strap hole and slightly exposed, the inner end of the clamping plate is squeezed and locked with the convex ball, and the leaf spring provides elasticity, such as the attached Figure 1 , the convex ball is outside and the gasket is inside. Then put it on your arm, move it close to the armpit, make the square ring on the outside of the arm, then pull the strap head outward with one hand to tighten the arm. If it is too tight, you can pull the T-shaped plate head outward to loosen the strap and reposition it. Next, you can do a fisting exercise to exercise the internal fistula blood vessels.

[0013] The arteriovenous fistula arm training belt only requires one person to put on the arm and perform subsequent adjustments. It can be tied stably and continuously, has good training effects, is easy to use, and has high practical value and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
