[0021] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0022] Embodiment 1: As Figures 1 - 3 , it includes a waist fixing band 100 with adjustable length. Both ends of the waist fixing band 100 are cooperatively installed with buckles 110. The waist fixing band 100 is a stretchable elastic band structure. The outer wall of the bottom of the waist fixing band 100 is rotatably connected to an elastic bandage 140. The bottom end of the elastic bandage 140 is connected to a compression hemostat. The compression hemostat includes a compression positioning band 200. Air bags 210 are arranged around the inner wall of the compression positioning band 200. A protective cover 220 is fixedly installed on the inner wall of the front end of the compression positioning band 200. A pressing seat 230 is connected to the inner wall of the protective cover 220. The bottom of the compression positioning band 200 is connected to a leg fixing band 250 through the elastic bandage 140.

[0023] The specific use scenario of this embodiment is: The waist fixing band 100 is set to fix with the waist. By setting the elastic bandage 140, the waist fixing band 100 and the compression positioning band 200 are fixedly connected. The protective cover 220 is set to position and protect the skin of the lower limb arteriovenous. The air bags 210 are set to form a support between the elastic bandage 140 and the skin, thereby improving the comfort of the skin. The pressing seat 230 is set to press the wound of the lower limb arteriovenous, thereby achieving the effect of hemostasis.

[0024] Embodiment 2: As Figures 1 - 3 , a hanging ring 120 is rotatably connected to the outer wall of the bottom of the waist fixing band 100. The hanging ring 120 and the compression positioning band 200 are fixedly connected through an ear hook 130. The compression positioning band 200 is made of a stretchable elastic material. An inflation port 211 is installed on the side wall of the air bag 210.

[0025] The specific use scenario of this embodiment is: By setting the hanging ring 120 that can be rotated to adjust the direction, it is convenient for the operator to flexibly adjust the angle of the compression positioning band 200, avoiding the phenomenon of the elastic bandage 140 being twisted to a certain extent, facilitating the elastic bandage 140 to fit the body, making the elastic bandage 140 present a flat shape, and improving the comfort of use.

[0026] Embodiment 3: As Figure 4 and Figure 5, the protective cover 220 is funnel-shaped. The port of the protective cover 220 passes through the airbag 210 to fasten the lower limb arteriovenous part. The outer end of the extrusion seat 230 is detachably threadedly connected to the rotating shaft 240. A handwheel 241 is fixedly installed on the outer wall of the rotating shaft 240. The connection between the outer wall of the rotating shaft 240 and the inner wall of the protective cover 220 is threadedly connected. The extrusion seat 230 cooperates to compress and stop bleeding at the lower limb arteriovenous part.

[0027] The specific usage scenario of this embodiment is as follows: By setting the protective cover 220 and the airbag 210 to be used in cooperation, it is used to enhance the friction with the patient's lower leg, facilitating the positioning of the lower limb arteriovenous part, thereby improving the compression and hemostasis of the extrusion seat 230 at the lower limb arteriovenous part. To a certain extent, it avoids the phenomenon of compression misalignment, improves the comfort of the patient during use, and improves the safety of use.

[0028] The working principle of the present utility model is as follows: When those skilled in the art use it, the waist fixing belt 100 is worn on the patient's waist through the buckle 110, and the compression positioning belt 200 is sleeved on the leg, so that the protective cover 220 can be aligned with the lower limb arteriovenous wound, and the lower limb arteriovenous wound is covered inside the protective cover 220. Then, by inflating through the inflation port 211, the airbag 210 can support the inner periphery of the compression positioning belt 200, improving the comfort of the patient's leg. The leg fixing belt 250 is sleeved and fixed on the outer wall of the patient's leg. By holding the handwheel 241 and rotating to adjust the extrusion seat 230 and the rotating shaft 240, the extrusion seat 230 compresses and stops bleeding at the wound on the surface of the lower limb arteriovenous.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model.
