Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a novel hemostatic bandage. Background Technology

[0002] Hemostatic bandages are key medical supplies used to control bleeding from wounds in emergency situations. They are widely used in battlefield first aid, outdoor adventures, and everyday accidents. Their core function is to quickly block blood flow through physical pressure and blood clotting assistance, buying time for wound healing or subsequent treatment.

[0003] However, traditional hemostatic bandages are typically made of basic materials such as ordinary gauze and elastic bandages, relying solely on physical compression and lacking active clotting components. For deeper or larger amounts of bleeding, prolonged and intense pressure is required to be effective. Furthermore, during the clotting process, blood easily seeps through the edges of the bandage, resulting in a dispersed hemostatic area that is difficult to apply accurately to the bleeding point, increasing the risk of blood loss. In addition, the traditional method of securing bandages involves simple wrapping, making it difficult to control the tightness. Too loose a bandage can lead to insufficient compression and displacement, while too tight a bandage can impede blood circulation. Therefore, we have introduced a new type of hemostatic bandage. Utility Model Content

[0004] The main objective of this invention is to provide a novel hemostatic bandage that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel hemostatic bandage includes a breathable protective layer, a pressure fixation layer, and an instant hemostatic layer;

[0007] The breathable protective layer includes antibacterial gauze, a polyester breathable membrane, a circular color-changing ink block, a first hook and loop fastener surface, and a first hook and loop fastener hook surface.

[0008] The pressure-fixing layer includes an elastic non-woven fabric, a spandex elastic band, and a second Velcro woven surface.

[0009] The instantaneous hemostatic layer comprises honeycomb absorbent cotton, chitosan sponge, thrombin coating, and a second Velcro hook side.

[0010] Preferably, the upper surface of the polyester breathable membrane is heat-pressed and laminated with the antibacterial gauze, and three circular color-changing ink blocks are provided. The three circular color-changing ink blocks are respectively printed on the left, middle and right sides of the upper surface of the polyester breathable membrane. The first hook and loop fastener is sewn to the left side of the upper surface of the polyester breathable membrane, and the first hook and loop fastener is sewn to the right side of the upper surface of the polyester breathable membrane.

[0011] By adopting the above technical solution: hot-pressing composite enhances the stability of interlayer connection, three circular color-changing ink blocks can monitor the blood penetration position, the first hook and loop side of the hook and loop side achieve convenient fixation, and take into account breathability, antibacterial and intuitive monitoring functions.

[0012] Preferably, three spandex elastic bands are provided, with the upper left and upper right portions of the three spandex elastic bands sewn to the lower left and lower right portions of the antibacterial gauze, respectively, and the lower left and lower right portions of the three spandex elastic bands sewn to the upper left and upper right portions of the elastic nonwoven fabric, respectively, and the second Velcro side is sewn to the lower edge of the elastic nonwoven fabric.

[0013] By adopting the above technical solution, the upper and lower ends of the three spandex elastic bands are sewn to antibacterial gauze and elastic non-woven fabric respectively, forming a stable pressure structure.

[0014] Preferably, the upper surface of the chitosan sponge is bonded to the lower surface of the honeycomb absorbent cotton with medical adhesive, the thrombin coating is uniformly sprayed on the lower surface of the chitosan sponge, and the second Velcro hook is sewn to the edge of the upper surface of the honeycomb absorbent cotton.

[0015] By adopting the above technical solution, the chitosan sponge and honeycomb absorbent cotton are firmly bonded together, and the thrombin coating is evenly distributed to ensure stable release of coagulation factors, thereby improving hemostasis efficiency.

[0016] Preferably, the three spandex elastic bands are distributed at equal intervals in pairs.

[0017] By adopting the above technical solutions, pressure is applied evenly to the wound, avoiding excessive or insufficient local pressure, enhancing the stability and comfort of compression, and reducing the problem of poor hemostasis caused by uneven pressure.

[0018] Preferably, the upper surface of the hook side of the second hook and loop fastener is bonded to the lower surface of the loop side of the second hook and loop fastener.

[0019] By adopting the above technical solution, the instantaneous hemostatic layer and the pressure fixation layer can be quickly disassembled and securely connected, ensuring that the instantaneous hemostatic layer does not shift during the compression process and ensuring that the coagulation components continue to act on the bleeding point.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this invention, the thrombin coating of the instant hemostatic layer directly contacts the wound and rapidly releases clotting factors. The chitosan sponge absorbs blood and activates the clotting reaction. The honeycomb absorbent cotton locks in the blood to prevent it from spreading. At the same time, the elastic non-woven fabric of the tension and pressure fixing layer and the three equidistant spandex elastic bands provide uniform and controllable pressure. With the fixation of the hook side and the loop side of the second hook and loop fastener, the instant hemostatic layer is ensured to fit tightly against the bleeding point and avoid displacement. Compared with traditional bandages, it achieves accurate and rapid hemostasis and reduces the situation of blood seeping to the edges. The circular color-changing ink block can be used for intuitive monitoring. When the left or right side changes color, the position can be adjusted in time to reduce the risk of blood loss.

[0022] 2. In this utility model, the first Velcro loop side and the first Velcro hook side of the breathable protective layer are bonded and fixed around the limb, and the tightness is easy to adjust, ensuring that the pressure of the pressure fixing layer is stable and does not affect blood circulation. The antibacterial gauze inhibits bacterial growth, and the polyester breathable membrane ensures air circulation, avoiding the wound from being stuffy and damp. At the same time, the circular color-changing ink block can intuitively display the blood penetration status, eliminating the need for frequent disassembly and inspection, reducing interference with the hemostasis process. Through the combination of these structures, the bandage can be stably fixed, and a clean and breathable environment can be provided for the wound, reducing the risk of infection and improving the safety and convenience of use.

The upper surface of the chitosan sponge 32 is bonded to the lower surface of the honeycomb absorbent cotton 31 with medical adhesive. The thrombin coating 33 is evenly sprayed on the lower surface of the chitosan sponge 32. The second hook and loop side 34 is sewn to the upper edge of the honeycomb absorbent cotton 31. The three spandex elastic bands 22 are distributed in pairs at equal distances. The upper surface of the second hook and loop side 34 is bonded to the lower surface of the second hook and loop side 23.

[0039] It should be noted that this utility model is a novel hemostatic bandage. When using it, open the packaging and take out the novel hemostatic bandage. Ensure that the thrombin coating 33 of the instant hemostatic layer 3 is facing down and the polyester breathable membrane 12 of the breathable protective layer 1 is facing up. Separate the first hook and loop side 14 from the first hook and loop side 15. After cleaning the skin around the wound, align the thrombin coating 33 of the instant hemostatic layer 3 with the bleeding site and gently press to ensure the chitosan sponge 32 completely adheres to the wound, ensuring coverage of all bleeding points. Tighten the elastic non-woven fabric 21 of the pressure fixing layer 2, applying moderate pressure to the wound using the contraction force of the three spandex elastic bands 22. Simultaneously, through the adhesive cooperation between the second hook and loop side 34 and the second hook and loop side 23, the instant hemostatic layer 3 and the...
