[0018] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art.

[0019] Example 1 Please refer to Figures 1 to 8 As shown, an emergency hemostasis device for field rescue includes a main body 1. The main body 1 has two symmetrically arranged winding cavities 2 inside, and a winding roller 3 is rotatably connected in the winding cavities 2. The left and right sides of the main body 1 have through grooves 4 that communicate with the winding cavities 2 on the same side. A fastening strap 5 is provided at the bottom of the main body 1. The two ends of the fastening strap 5 extend into the two winding cavities 2 through the through grooves on both sides and are fixedly connected to the winding roller 3 in the winding cavities 2. A linkage assembly 6 is provided at the rear of the main body 1 and is connected to the rear end of the roller shaft of the two winding rollers 3. A drive assembly 7 is provided at the front of the main body 1 and is connected to the front end of the roller shaft of one of the winding rollers 3. A mounting plate 9 is connected to the bottom of the main body 1 through two elastic components 8. A backing layer 10 is fixedly connected to the bottom of the mounting plate 9. A hemostatic cotton 11 is provided at the bottom of the backing layer 10. The hemostatic cotton 11 and the backing layer 10 are detachably connected by Velcro.

[0020] Those skilled in the art will understand that when the drive component 7 drives a single take-up roller 3 to rotate, the linkage component 6 can drive another take-up roller 3 to move synchronously, realizing the synchronous winding and release of both ends of the fastening band 5. The elastic component 8 allows the hemostatic cotton 11 to fit elastically against the limb. The hemostatic cotton 11 connected by Velcro can be quickly disassembled and replaced. The whole structure forms an integrated emergency hemostasis structure, realizing the combination of fastening and pressure and hemostasis. It solves the problems of the dispersed structure and cumbersome operation of traditional hemostasis devices, and improves the overall efficiency of hemostasis in the field.

[0021] Example 2 Furthermore, the inside of the through groove 4 is rotatably connected to two guide rollers 12 that are spaced apart vertically, and the fastening band 5 is inserted between the two guide rollers 12.

[0022] Those skilled in the art will understand that when the take-up roller 3 takes up or releases the fastening belt 5, the guide roller 12 rotates synchronously with the movement of the fastening belt 5, providing guidance and limiting for the fastening belt 5 throughout its movement. This prevents the fastening belt 5 from shifting, getting stuck, or rubbing hard against the inner wall of the through groove 4, ensuring the smooth movement of the fastening belt 5, reducing wear on the fastening belt 5, extending its service life, and ensuring that the take-up and release of the fastening belt 5 always maintains a straight trajectory, thus improving the stability of the fastening pressure.

[0023] Example 3 Furthermore, two symmetrically distributed guide rods 13 are fixedly connected to the top of the mounting plate 9, and guide sliding holes 14 adapted to the two guide rods 13 are opened at the bottom of the main body 1. The guide rods 13 are slidably connected in the adapted guide sliding holes 14.

[0024] Those skilled in the art will understand that when the elastic component 8 is subjected to force and drives the mounting plate 9 to move up and down, the guide rod 13 slides precisely in a straight line along the guide sliding hole 14, providing guidance and constraint for the movement of the mounting plate 9, preventing the mounting plate 9 from shifting, shaking or tilting during the movement, ensuring that the hemostatic cotton 11 at the bottom of the backing layer 10 is always precisely aligned and tightly fitted with the bleeding site of the injured person, avoiding the problem of poor hemostasis effect caused by misalignment, and improving the accuracy of hemostasis.

[0025] Example 4 Furthermore, a positioning groove 15 is provided on the rear side of the main body 1, and a protective shell 16 is inserted into the positioning groove 15. The protective shell 16 covers the outside of the linkage component 6. An installation ring plate 17 is fixedly connected to the outer wall of the protective shell 16. A sealing gasket 18 is fixedly connected to the side of the installation ring plate 17 facing the main body 1. Fixing screws 19 are provided at the four corners of the installation ring plate 17. Screw holes corresponding to each fixing screw 19 are provided on the rear side of the main body 1.

[0026] As will be understood by those skilled in the art, the protective shell 16 completely covers the outside of the linkage component 6, effectively preventing debris such as mud, branches, and gravel in the field from contacting the linkage component 6, thus avoiding component jamming, gear meshing wear, and other malfunctions. The sealing gasket 18 fills the gap between the protective shell 16 and the main body 1, improving the protective sealing performance and preventing moisture and fine sand from entering. The fixing screws 19 enable the protective shell 16 to be firmly installed and easily disassembled, ensuring the normal transmission of the linkage component 6 in complex field environments and facilitating subsequent inspection, maintenance, and cleaning of the linkage component 6, thereby improving the field durability of the device.

[0027] Example 5 Furthermore, the backing layer 10 is made of woven fabric and has an airbag 20 inside. An air pump 21 is fixedly connected to the front side of the main body 1. The output end of the air pump 21 is connected to an air tube 22. The other end of the air tube 22 extends into the backing layer 10 and is connected to the airbag 20.

[0028] Those skilled in the art will understand that, during use, the airbag 20 can be inflated by starting the air pump 21. The airbag 20 gradually expands according to the amount of air, causing the woven fabric backing layer 10 to flexibly deform to conform to the contour of the human limb. This allows the hemostatic cotton 11 to achieve a comprehensive and tight flexible fit with the bleeding site of the limb, adapting to human limbs of different thicknesses and shapes. At the same time, the fitting pressure can be precisely adjusted by controlling the inflation volume of the air pump 21 to achieve graded pressure hemostasis, avoiding secondary injury to the limb due to excessive pressure. The woven fabric backing layer 10 combines flexibility, abrasion resistance, and breathability, improving the comfort of the injured person during hemostasis and solving the problems of poor limb compatibility and inflexible pressure adjustment of traditional devices.

[0029] Example 6 Furthermore, the main body 1 is made of hard lightweight alloy material, and a weight reduction groove 23 is vertically opened at the top center of the main body 1.

[0030] As those skilled in the art will understand, the hard lightweight alloy material ensures that the main body 1 has sufficient structural strength to withstand external forces such as compression, collision, and pulling during field rescue, preventing deformation and damage to the main body 1, while significantly reducing the overall weight of the main body 1. Combined with the design of the weight reduction groove 23, the total weight of the device is further reduced, reducing the burden carried by rescuers. At the same time, the lightweight main body 1 is easier for rescuers to operate with one hand, solving the problems of traditional hemostasis devices being heavy, inconvenient to carry, and difficult to operate, thus improving the device's field portability and ease of operation.

[0031] Example 7 Furthermore, the linkage assembly 6 includes two first gears 601 rotatably connected to the rear side of the main body 1 and distributed in a left-right manner. The rear ends of the roller shafts of the two take-up rollers 3 extend to the rear side of the main body 1 and are fixedly connected to second gears 602. The two second gears 602 mesh with the two first gears 601 respectively, and the two first gears 601 mesh with each other.

[0032] Those skilled in the art will understand that when the drive assembly 7 drives one of the take-up rollers 3 to rotate, the take-up roller 3 drives the corresponding second gear 602 to rotate, which in turn drives the meshing first gear 601 to rotate. Through the meshing of the two first gears 601, the power is transmitted to the other first gear 601, which drives the meshing second gear 602 and the other take-up roller 3 to rotate synchronously. This achieves synchronous and same-speed winding and unwinding of the two take-up rollers 3 on both ends of the fastening band 5, ensuring that the tightening force at both ends of the fastening band 5 is uniform and consistent. This makes the fastening pressure of the device on the human limb evenly distributed along the circumference, avoiding local pressure injury to the limb caused by excessive tightening force on one side, and improving the safety and uniformity of fastening and hemostasis.

[0033] Example 8 Furthermore, the drive assembly 7 includes a first housing 701 fixedly connected to the front side of the main body 1, wherein the front end of the roller shaft of a take-up roller 3 extends into the first housing 701 and is fixedly connected to a turntable 702, a connecting shaft 703 is fixedly connected to the front side of the turntable 702, the front end of the connecting shaft 703 extends into the first housing 701 and is fixedly connected to a knob 704, and the outer ring of the knob 704 is provided with an anti-slip surface.

[0034] Those skilled in the art will understand that rescuers can manually adjust the winding force of the fastening belt 5 by rotating the knob 704, which drives the turntable 702 and the winding roller 3 to rotate via the connecting shaft 703. The first housing 701 can protect the internal turntable 702 from collisions or jamming by external debris. The anti-slip surface of the outer ring of the knob 704 increases the friction between the hand and the knob 704, effectively preventing slippage even when rescuers are wearing gloves in the field, ensuring operational stability, achieving precise control of the tightening force of the fastening belt 5, and improving the convenience and accuracy of device operation.

[0035] Example 9 Furthermore, a second housing 705, which communicates with the first housing 701, is fixedly connected to the front side of the main body 1. A slider 706 is slidably arranged inside the second housing 705. A locking block 707 is fixedly connected to the side of the slider 706 near the first housing 701. Several locking grooves 708 that cooperate with the locking block 707 are evenly opened on the outer ring of the turntable 702. The insertion end of the locking block 707 is provided with a bevel. A pull rod 709 is fixedly connected to the side of the slider 706 away from the locking block 707. The end of the pull rod 709 away from the slider 706 extends to the outside of the second housing 705 and is rotatably connected to a locking plate 710. A first spring 711 is sleeved on the pull rod 709. One end of the first spring 711 is fixedly connected to the inside of the second housing 705, and the other end of the first spring 711 is fixedly connected to the slider 706. A hook 712 that matches the locking plate 710 is fixedly connected to the front side of the main body 1.

[0036] Those skilled in the art will understand that when the knob 704 is turned to wind up the fastening band 5, the protruding part of the turntable 702 pushes the locking block 707 and the slider 706 through the inclined surface to compress the first spring 711 and retract. After the knob 704 is released, the restoring force of the first spring 711 pushes the slider 706 and the locking block 707 into the locking groove 708, thereby realizing the automatic locking of the turntable 702 and the winding roller 3, preventing the fastening band 5 from loosening due to the reaction force of the limb, and ensuring the stability of the pressure. If unlocking is required, the pull rod 709 is pulled to drive the locking block 707 out of the locking groove 708, and the locking plate 710 is engaged with the hook 712, which can keep the unlocked state and facilitate the reverse rotation of the knob 704 to release the fastening band 5. This structure realizes the automatic locking and convenient unlocking of the fastening band 5, avoids the failure of hemostasis due to the loosening of the device, and improves the reliability of the device.

[0037] Example 10 Furthermore, the elastic component 8 includes a mounting groove 801 formed at the bottom of the main body 1. Two parallel sliding rods 802 are fixedly connected in the mounting groove 801. Two sliding sleeves 803 are slidably connected to the two sliding rods 802. Two second springs 804 are fixedly connected to the opposite sides of the two sliding sleeves 803. The other ends of the two second springs 804 are fixedly connected to the side wall of the mounting groove 801. The two second springs 804 are respectively sleeved on the two sliding rods 802. The bottom ends of the two sliding sleeves 803 are hinged to support rods 805. The other ends of the support rods 805 are hinged to the top of the mounting plate 9.

[0038] Those skilled in the art will understand that when the fastening band 5 is tightened to bring the device into contact with the limb, the limb exerts a reaction force on the mounting plate 9, pushing the support rod 805 to swing around the hinge point. This, in turn, causes the two sliding sleeves 803 to move away from each other along the sliding rod 802, compressing the second spring 804. The restoring force of the second spring 804 forms a reverse buffering force and a contacting force, pushing the mounting plate 9 towards the limb, so that the hemostatic cotton 11 can achieve an elastic contact with the limb. This can adapt to the slight movement of the limb and different stress states, avoiding excessive local pressure caused by rigid contact. The sliding rod 802 provides precise guidance for the movement of the sliding sleeves 803, preventing the sliding sleeves 803 from deviating or getting stuck, ensuring the stable transmission of the elastic component 8, and improving the comfort and tightness of the contact during hemostasis.

[0039] The working principle and usage procedure of this device are as follows: First, the fastening strap 5 is placed over the bleeding limb of the injured person. Sterile hemostatic cotton 11 is quickly attached to the bottom of the backing layer 10 using Velcro. Then, the hemostatic cotton 11 is precisely aligned with the bleeding site of the injured person's limb, allowing it to initially adhere to the limb surface. Next, the rescuer holds the main body 1 and rotates the knob 704. The knob 704, through the connecting shaft 703, drives the turntable 702 inside the first housing 701 to rotate, which in turn drives one of the winding rollers 3 connected to the turntable 702 to rotate. The rear end of the winding roller 3 drives the corresponding second gear 602 to rotate. The second gear 602 drives the meshing first gear 601 to rotate. Through the meshing of the two first gears 601, power is transmitted to the other first gear 601 and the corresponding second gear 602, driving the other winding roller 3 to rotate synchronously. This achieves synchronous winding of the two winding rollers 3 around both ends of the fastening strap 5. When the turntable 702 rotates, its outer protruding part is locked by the locking block 707. The inclined surface at the insertion end pushes the locking block 707 and slider 706 to compress the second spring 804 and retract. When the knob 704 is released to stop winding, the restoring force of the first spring 711 pushes the slider 706 and locking block 707 into the locking groove 708 on the outer ring of the turntable 702, realizing the automatic locking of the winding roller 3 and preventing the fastening band 5 from loosening. During the process of the fastening band 5 tightening to make the device fit against the limb, the limb generates a reaction force on the mounting plate 9, pushing the support rod 805 of the elastic component 8 to swing around the hinge point. The two sliding sleeves 803 move closer to each other along the sliding rod 802 in the mounting groove 801 and compress the second spring 804. The return force of the second spring 804 enables the mounting plate 9 to fit elastically with the limb. If further pressure is needed on the bleeding site, the air pump 21 is started. The air pump 21 inflates the air bag 20 through the air tube 22. The expansion of the air bag 20 causes the woven fabric backing layer 10 to deform flexibly, so that the hemostatic cotton 11 fits tightly with the contour of the limb in all directions. The pressure can be adjusted according to the injury by the amount of air.
