[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-3 An arteriovenous compression belt shown includes a compression belt body 1 and a gauze ball 3 installed at the lower end of the compression belt body 1;

[0025] A cotton core 4 is provided on the lower side of the gauze ball 3;

[0026] A self-adhesive layer 5 is embedded in the leftmost part of the outer wall of the lower end of the pressing belt body 1;

[0027] The leftmost part of the upper outer wall of the pressing belt body 1 is fixedly connected with a pull ear 2. After the patient has completed blood sampling or removed the infusion needle, the lower side of the cotton core 4 can be pressed against the needle eye and pressed downward. Then, the self-adhesive layer 5 on the right side of the pressing belt body 1 is wrapped around the arm or wrist, passed through the pull ear 2, and pasted on the pressing belt body 1 to limit the pressing belt body 1, so as to keep pressing on the needle eye.

[0028] A roller 6 is provided on the inner wall of the right end of the pull ear 2, and a plurality of protrusions 10 are fixedly connected to the circular outer wall of the roller 6 at equal intervals. When the self-adhesive layer 5 passes through the pull ear 2, the adhesive surface contacts the pull ear 2 and can contact the protrusions 10 on the circular outer wall of the roller 6, and drive the roller 6 to rotate, thereby avoiding the adhesive surface from contacting the pull ear 2 over a large area, and reducing the consumption of the adhesive surface coating.

[0029] like Figure 4 and Figure 5 As shown, a groove 9 opening to the left is provided inside the outer wall of the right end of the pull ear 2 to provide a rotation space for the roller 6, and positioning grooves 7 opening opposite to each other are provided inside the inner walls at the upper and lower ends of the groove 9. The outer walls at the upper and lower ends of the roller 6 are fixedly connected with positioning rods 8 passing through the positioning grooves 7 to limit the rotation position of the roller 6, and the upper ends of the multiple protrusions 10 are all sharp.

[0030] When the roller 6 rotates, the space occupied by the roller 6 inside the pull ear 2 can be reduced through the space in the groove 9, so that the belt pressing body 1 can pass through the pull ear 2 more smoothly. During the rotation of the roller 6, the positioning rod 8 rotates inside the positioning groove 7 to limit the position of the roller 6 during rotation. The sharp protrusion 10 can reduce the contact area with the self-adhesive layer 5 and reduce the loss of the adhesive layer.

[0031] like Figure 4 and Figure 5As shown, positioning blocks are fixedly connected to the lower sides of the left and right ends of the positioning rod 8, and clamping grooves are provided on the lower sides of the inner walls of the left and right ends of the positioning groove 7 for the positioning blocks to clamp and limit the position of the roller 6. The multiple protrusions 10 are made of plastic material, and the roller 6 can rotate clockwise and counterclockwise under the restriction of the positioning rod 8.

[0032] The positioning block is clamped in the clamping groove to prevent the roller 6 from shaking during rotation. At the same time, the raised block 10 made of plastic material has a light weight, which makes it easier for the self-adhesive layer 5 to drive the roller 6 to rotate.

[0033] like Figure 1 and Figure 2 As shown, the cotton core 4 is hemispherical, and the cotton core 4 and the pressure belt body 1 are fixedly connected by using a medical adhesive. The pull ear 2 is made of plastic material, and the pressure belt body 1 is made of non-woven fabric.

[0034] The hemispherical cotton core 4 can contact the patient's pinhole more comprehensively, and after being fixedly connected by an adhesive, the cotton core 4 can be prevented from falling off during the taking process.

[0035] The implementation principle of this embodiment is as follows: after the patient has completed blood sampling or has removed the infusion needle, the lower side of the cotton core 4 can be placed against the needle eye and pressed downward, and then the self-adhesive layer 5 on the right side of the pressure belt body 1 is passed around the arm or wrist, passed through the pull ear 2, and pasted on the pressure belt body 1 to restrict the pressure belt body 1, so as to maintain the pressure on the needle eye. When the self-adhesive layer 5 passes through the pull ear 2, the adhesive surface contacts the pull ear 2, and can contact the raised block 10 on the circular outer wall of the roller 6, and drive the roller 6 to rotate, so as to avoid the situation where the adhesive surface contacts the pull ear 2 over a large area, thereby reducing the consumption of the adhesive surface coating.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
