[0034] In this embodiment, the two ends of the elastic mesh bag 2 are respectively provided with a first Velcro 206 and a second Velcro 207 that can contact and fix with each other. The first Velcro 206 and the second Velcro 207 can connect the hemostatic pad 1 and the airbag cushion 205 end to end and bend them into a circular shape to be fixed on the patient's limbs.

[0035] The first magic tape 206 is provided at one end close to the placement slot 204 , and the second magic tape 207 is provided at one end away from the placement slot 204 . The first magic tape 206 is a rounded rectangle, and the second magic tape 207 is a slender strip.

[0036] Specifically, a plurality of ventilation holes are provided on the surface of the elastic mesh bag 2 , through which air can circulate inside the hemostatic pad 1 and the elastic mesh bag 2 , thereby preventing the patient's wound from being too stuffy and thus affecting wound healing.

[0037] Specifically, the inner side of the hemostatic pad 1 is coated with a hemostatic agent.

[0038] In this embodiment, three placement bags 201 are sewn onto the outer side of the elastic mesh bag 2. An ice box 202 is inserted into the interior of the placement bag 201. The ice box 202 is filled with cold water. The ice box 202 is placed in a refrigerator for quick freezing before use. The frozen ice box 202 has an analgesic effect on the patient's wound, making the patient more comfortable and not too painful.

[0039] In this embodiment, a through hole 203 is formed on one side of the placement slot 204 .

[0040] See Figure 1 and Figure 4 A one-way air inlet hole 301 is opened at one end of the extruded airbag 3, and an air supply pipe 302 is fixed and connected to the other end of the extruded airbag 3. A one-way tube 4 is fixed and connected to the airbag cushion 205, and the air supply pipe 302 is connected to the one-way tube 4 through the through hole 203.

[0041] See Figure 5 A spiral groove 401 is provided at the end of the one-way tube 4 away from the airbag cushion 205, one end of the spiral groove 401 is provided with an internal thread, and one end of the air supply pipe 302 is provided with an external thread, and the spiral groove 401 is threadedly connected to the air supply pipe 302; a rectangular structure with an arc surface is fixedly connected to the end of the one-way tube 4 close to the airbag cushion 205, and the arc surfaces at both ends of the rectangular structure match the arc-shaped inner wall of the one-way tube 4, the rectangular structure is fixedly connected to one end of the spring 403, and the other end of the spring 403 is fixedly connected to a blocking block 402, and a gap is formed between the blocking block 402 and the inner wall of the one-way tube 4 during inflation or deflation to enable gas to enter the airbag cushion 205, and the blocking block 402 can be matched and connected with the spiral groove 401 after inflation stops to achieve a blocking function.

[0042] The working principle of the inflatable wound dressing hemostasis auxiliary device in this embodiment is as follows:

[0043] (1) First, install the hemostatic pad 1 and the airbag pad 205 on the elastic mesh bag 2, then cover the patient's wound with the hemostatic pad 1, and wrap the hemostatic pad 1 and the elastic mesh bag 2 in a ring shape around the patient's arm or wrist near the wound, and then fit the second Velcro 207 with the first Velcro 206 to complete the fixation of the entire inflatable wound dressing hemostasis auxiliary device on the affected area.

[0044] (2) When air supply is required, the airbag 3 is manually pressed. When the airbag 3 is subjected to pressure, the gas inside the airbag 3 enters the airbag cushion 205 along the one-way tube 4, causing the airbag cushion 205 to swell. When the airbag 3 is relaxed, due to its good elasticity, the airbag 3 will generate suction when it returns to its original shape, causing external gas to enter the airbag 3 through the one-way air inlet 301, and continue to inflate the airbag cushion 205, causing the airbag cushion 205 to swell until the affected area is tightly fitted with the hemostatic pad 1; wherein, the one-way The air inlet 301 prevents gas from being discharged through the one-way air inlet 301 when the squeeze airbag 3 is under pressure. When the air delivery tube 302 delivers gas to the airbag cushion 205 through the one-way tube 4, the blockage 402 is pressured and moves downward, allowing gas to enter the airbag cushion 205. When the gas delivery stops, the blockage 402, acting under the action of the spring 403, moves upward, blocking the one-way tube 4 and preventing the gas inside the airbag cushion 205 from escaping, thereby preventing gas leakage. During the air delivery process, the degree of inflation of the airbag cushion 205 varies from person to person. Since patients have different body shapes and withstand varying forces in real life, the degree of inflation of the airbag cushion 205 can be determined based on the patient's own physical sensation, without the need for an external instrument to display the information.

[0045] (3) After hemostasis is completed, the airbag cushion 205 is deflated. A wooden stick with a diameter smaller than that of the one-way tube 4 is inserted into the one-way tube 4 to apply pressure to the blocking block 402 so that the blocking block 402 no longer blocks the one-way tube 4. The gas inside the airbag cushion 205 can be discharged. When deflation occurs, the wound dressing hemostasis auxiliary device needs to be removed.

[0046] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
