[0018] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figs. 1 to 3 As shown, this embodiment discloses a hemostatic bandage for dialysis arteriovenous fistula with elastic pressure block, including a long and elastic elastic band 1 and a gauze block 2. A pressure pad 3 is connected to the elastic band 1. A flexible adhesive layer 4 and several adhesive points 5 are provided on the front side of the pressure pad 3. The several adhesive points 5 are arranged around the flexible adhesive layer 4. A protective film 6 is also provided on the front side of the pressure pad 3, and the protective film 6 covers the flexible adhesive layer 4 and the several adhesive points 5.

[0020] After the protective film 6 is removed, the flexible adhesive layer 4 adheres to the gauze pad 2, and the adhesive points 5 adhere to the skin, effectively preventing the gauze pad 2 from shifting. The flexible adhesive layer 4 can be medical-grade rubber or a silicone film. The adhesive points 5 can be made of silicone. A certain distance is designed between adjacent adhesive points 5 to facilitate the breathability of the gauze pad 2.

[0021] In this embodiment, the compression pad 3 has a hollow structure, and an air bladder 7 is disposed in the cavity of the compression pad 3. An inflation tube 701 is connected to the air bladder 7, extending to the outside of the compression pad 3. An inflation / deflation control valve 702 is disposed on the inflation tube 701. The pressure of the gauze block 2 on the surgical site can be adjusted by inflating or deflating the air bladder 7. The inflation device can be a syringe.

[0022] To better achieve hemostasis by applying pressure to the surgical site, both the pressure pad 3 and the airbag 7 can be designed to be flat.

[0023] In this embodiment, the elastic band 1 and the pressure pad 3 can be detached. An airbag inlet 301 is provided on the top of the pressure pad 3, and an air tube outlet 302 is provided on the side of the pressure pad 3. When the elastic band 1 and the pressure pad 3 are separated, the airbag 7 can be put into the pressure pad 3 through the airbag inlet 301, or the airbag 7 can be taken out of the pressure pad 3.

[0024] In this embodiment, as a way to detach and connect the elastic band 1 and the pressure pad 3, a guide sleeve 8 is provided on the elastic band 1, and the guide sleeve 8 is connected to the top of the pressure pad 3 through a first Velcro 9.

[0025] In this embodiment, the two ends of the elastic band 1 are connected by the second Velcro 10.

[0026] It should be noted that hook and loop fasteners include a loop side and a hook side, and the position of the loop side and hook side can be fixed according to the specific situation.

[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
