[0002] In medical practice, blood drawing or injection is a common diagnosis and treatment operation. After the patient is subjected to blood drawing or injection, he usually needs to apply a hemostatic patch to the wound site and press for a period of time to stop the bleeding. However, the existing hemostatic patch and cotton swab pressing methods have the following problems: First, it is difficult for the patient to maintain constant pressure and time when pressing by himself, which may lead to incomplete hemostasis or prolong the hemostasis time; second, medical staff may not be able to continue to pay attention to the pressing situation of each patient during their busy work, resulting in unstable hemostasis effect.

[0003] Chinese patent CN220898741U discloses an adjustable compression-type hemostatic first aid device, including a bandage, a hemostatic cotton cloth and an air bag. The air bag is provided with an inflation port, and the inflation port is connected to an inflation device. The inflation device inflates the air bag and applies pressure to the bandage to compress the hemostatic cotton cloth on the patient's limb to stop bleeding. However, the first aid device requires manually adjusting a control valve to control the inflation and deflation of the air bag, which is more troublesome to use. Summary of the invention

[0004] The purpose of the present invention is to provide an inflatable wound dressing hemostasis auxiliary device in order to overcome the defects of the above-mentioned prior art. The hemostasis auxiliary device has good compression effect, can evenly bear force, and effectively absorb blood.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The present invention provides an inflatable wound dressing hemostasis auxiliary device, comprising a hemostatic pad, an elastic mesh bag is sewn on the outer side of the hemostatic pad, a placement groove is opened on the elastic mesh bag, an airbag cushion is fixedly arranged in the placement groove, an extrusion airbag is arranged on the outer side of the elastic mesh bag, the extrusion airbag is connected to the airbag cushion, the extrusion airbag inflates the airbag cushion and applies pressure to the hemostatic pad, so as to press the hemostatic pad against the patient's wound to stop bleeding.

[0007] Furthermore, the two ends of the elastic mesh bag are respectively provided with a first Velcro and a second Velcro that can contact and fix each other. The first Velcro and the second Velcro can connect the hemostatic pad and the airbag pad end to end and bend them into a circular shape to be fixed on the patient's limbs.

[0008] Furthermore, the first Velcro is arranged at one end close to the placement slot, and the second Velcro is arranged at one end away from the placement slot. The first Velcro is a rounded rectangle, and the second Velcro is a slender strip.

[0009] Furthermore, a plurality of ventilation holes are provided on the surface of the elastic mesh bag, and the ventilation holes can allow air to circulate inside the hemostatic pad and the elastic mesh bag, thereby preventing the patient's wound from being too stuffy and thus affecting wound healing.

[0010] Furthermore, the inner side of the hemostatic pad is coated with a hemostatic agent.

[0011] Furthermore, a plurality of placement bags are sewn onto the outer side of the elastic mesh bag, and ice boxes are inserted into the interior of the placement bags.

[0012] Furthermore, the ice box is filled with cold water, and the ice box is placed in a refrigerator for quick freezing before use. The frozen ice box has an analgesic effect on the patient's wound, so that the patient will not feel too much pain.

[0013] Furthermore, a through hole is provided on one side of the placement groove.

[0014] Furthermore, a one-way air inlet hole is opened at one end of the extruded airbag, an air pipe is fixed and connected to the other end of the extruded airbag, a one-way tube is fixed and connected to the airbag cushion, and the air pipe is connected to the one-way tube through the through hole.

[0016] A rectangular structure with an arc surface is fixedly connected to one end of the one-way tube near the airbag cushion. The arc surfaces at both ends of the rectangular structure match the arc-shaped inner wall of the one-way tube. The rectangular structure is fixedly connected to one end of a spring. A blocking block is fixedly connected to the other end of the spring. A gap exists between the blocking block and the inner wall of the one-way tube during inflation or deflation to allow gas to enter the airbag cushion. After inflation stops, the blocking block can be matched and connected with the spiral groove to achieve a sealing function.

[0017] Furthermore, when the squeezed airbag is not subjected to pressure, the airbag cushion is in a deflated state.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) The present invention covers the patient's wound with a hemostatic pad, then wraps the hemostatic pad and the elastic mesh bag in a ring shape around the arm or wrist near the wound, and then fits the second Velcro with the first Velcro to complete the fixation of the entire inflatable wound dressing hemostatic auxiliary device. Then, by applying pressure to the extrusion airbag, the airbag cushion is inflated to make the airbag cushion swell until the hemostatic pad fits tightly against the wound. The structure is simple and easy to use, and the force can be well controlled. By inflating the airbag cushion, the close fit between the hemostatic pad and the affected area can be adjusted, so that the hemostatic pad will not be too tightly attached to the skin and cause blood to be unable to circulate, thereby ensuring the hemostatic effect. The device can be widely used in various parts of the body, especially limb trauma.

[0020] (2) The hemostatic pad and the airbag pad of the present invention can be installed and replaced separately, and the elastic mesh bag can be used multiple times after cleaning and disinfection, thus saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

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

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

[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 on the outer side of the elastic mesh bag 2, and 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 also Figure 1 and Figure 4 A one-way air inlet hole 301 is opened at one end of the extrusion airbag 3, and an air supply pipe 302 is fixed and connected to the other end of the extrusion 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 also Figure 5 A spiral groove 401 is provided at one 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, 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 one 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 a spring 403, and a blocking block 402 is fixedly connected to the other end of the spring 403, and a gap exists 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 the 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 hemostatic pad 1 on the patient's wound, 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 hemostatic auxiliary device on the affected area.

[0044] (2) When air delivery 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 state, 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 attached to the hemostatic pad 1; wherein, the one-way The air inlet 301 prevents the gas from being discharged through the one-way air inlet 301 when the extruded airbag 3 is subjected to pressure. When the air delivery pipe 302 delivers gas to the airbag cushion 205 through the one-way pipe 4, the blocking block 402 moves downward under pressure, thereby allowing the gas to enter the inside of the airbag cushion 205. When the gas stops being delivered, the blocking block 402 moves upward under the action of the spring 403, blocking the one-way pipe 4, so that the gas inside the airbag cushion 205 cannot be discharged, thereby ensuring that the gas inside the airbag cushion 205 will not leak. During the gas delivery process, the degree of inflation of the airbag cushion 205 varies from person to person. Since the body shapes of patients in real life are different and the forces they bear are also different, the inflation degree of the airbag cushion 205 can be judged according to the patient's own body feeling, without the need for external instruments to display and judge.

[0045] (3) When 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 to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
