Technical Field
[0001] This invention relates to the field of field training medical care technology, specifically a portable multifunctional hemostasis and bandaging device suitable for field environments. Background Technology
[0002] As is well known, field training requires long-term outdoor activities. The medical personnel accompanying the team are the main frontline treatment providers, and the medical stations are the transfer and treatment nodes. The focus is on dealing with training injuries, environmental emergencies, and sudden traumas. For minor external injuries, it is necessary to clean and stop the bleeding in time before transferring to the medical area, especially when far from the camp, it is necessary to ensure that the wound is clean.
[0003] Due to the limitations of the field environment, it is inconvenient to carry a large amount of medical equipment to the camp. Therefore, most hemostasis is achieved by wrapping or compressing with bandages. During high-intensity training, especially when there is a shortage of medical personnel, trainees have difficulty performing quick treatment on their own. Furthermore, the protection of bleeding wounds is poor when conducting field operations far from the camp. Even if bandages are applied to stop the bleeding, there is still a high possibility of contamination. In addition, simple bandages can easily affect the normal activities of personnel and are inconvenient to use. Based on the problems mentioned above, we found that the existing hemostasis and bandaging process is difficult to avoid these problems at the same time. Therefore, we propose a portable multi-functional hemostasis and bandaging device suitable for field environments. It can be carried in one piece to field camps and can also be used to perform a certain degree of rapid wound bandaging when medical personnel are lacking. At the same time, it can be disassembled and carried separately with the help of the optimized bandaging module, so as to effectively protect the wound position and perform hemostasis when far away from the camp. Summary of the Invention
[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a portable, multifunctional hemostasis and bandaging device suitable for field environments. It can be carried in one piece to field camps for use, and can also perform a certain degree of rapid wound bandaging when medical personnel are lacking. At the same time, it can be detached and carried separately with the help of an optimized bandage module, so as to effectively protect the wound site and stop bleeding when far from the camp.
[0005] (II) Technical Solution The above-mentioned technical objective of the present invention is achieved through the following technical solution: a portable multi-functional hemostasis and bandaging device suitable for field environments, comprising an integrated chassis and several bandaging straps, a pull-out frame fixedly connected to the front side of the integrated chassis, a pull-out bracket inserted into the inner side of the pull-out frame, several locking strips fixedly connected to both sides of the inner side of the pull-out bracket, the two sides of the bandaging straps being located inside the left and right locking strips respectively, a container can fixedly connected to both sides of the bottom of the integrated chassis, a sub-frame fixedly connected to the front side of the pull-out frame, an arc-shaped shelf fixedly connected to the bottom of the integrated chassis, an arc-shaped outer shell fixedly connected to the inner side of the arc-shaped shelf, a transparent sheet fixedly connected to the inner side of the arc-shaped outer shell, and a photoelectric sensor fixedly connected between the arc-shaped outer shell and the arc-shaped shelf; The integrated chassis has a connecting beam on its inner side, and two connecting frames are slidably connected to the inner side of the connecting beam. The bottom of the connecting frame is fixedly connected to a locking fork.
[0006] Using the above technical solution, by setting up an integrated chassis, a single device can be directly carried to the field camp. Before use, the pull-out frame can be pulled out from the top of the pull-out frame. Then, the canvas layer of the bandage is facing upwards, and the protective film is torn off and inserted into the inside of the locking strip to complete the pre-loading. Then, the pull-out frame is reinserted into the pull-out frame. When the limbs of the personnel need to be bandaged, the limb can be directly inserted between the curved shell and the pull-out frame, with the wound position at the bottom of the pull-out frame. When the photoelectric sensor detects the limb insertion and stops moving, the connecting beam can move downwards until the front opening of the locking fork is located outside the bottom bandage. Then it moves forward until it is locked at the top and bottom of the bandage, and presses down to pull the bottom bandage off the inside of the locking strip. During the continuous pressing process, the bandage adheres to the wound position, and as the connecting beam continues to fall, the bandage eventually slides off the inside of the fork, so that the bandage falls in the required position.
[0007] The present invention is further configured such that: a bidirectional lead screw is rotatably connected to the inner side of the connecting beam, the outer side of the bidirectional lead screw is threadedly connected to the inner side of the two connecting frames, a servo motor is fixedly connected to the right side of the connecting beam, and the output end of the servo motor is fixedly connected to the bidirectional lead screw.
[0008] By adopting the above technical solution, by setting a double-rotation lead screw, when the servo motor drives the double-rotation lead screw to rotate forward or reverse, the two connecting frames are simultaneously extended or brought closer to each other under the limit of the connecting beam inside, so as to adjust the relative position of the two forks.
[0009] The present invention is further configured such that: both sides of the connecting beam are fixedly connected with side ears, the inner side of the side ears is slidably connected with a limit strip, the inner side of the integrated chassis is provided with a lifting frame, the front side of the lifting frame is fixedly connected to the limit strip, and the bottom of the limit strip is fixedly connected with a force-bearing frame.
[0010] By adopting the above technical solution, by setting side ears in conjunction with limiting strips, the side ears will slide along the limiting strips when the connecting beam moves horizontally, thereby limiting the movement of the connecting beam. The set lifting mechanism will work with the load-bearing frame to connect the structure and assist in bearing the load.
[0011] The present invention is further configured such that: a frame is fixedly connected to the front side of the lifting frame, a first electric cylinder is fixedly connected to the inner side of the frame, the bottom of the frame is fixedly connected to the force-bearing frame, and the telescopic end of the first electric cylinder is fixedly connected to the connecting beam.
[0012] By adopting the above technical solution, a frame is set up to install a first electric cylinder on the front side of the lifting frame, and the connecting beam is moved back and forth by pushing and pulling the first electric cylinder.
[0013] The present invention is further configured such that: a second electric cylinder is fixedly connected to the top of the integrated chassis, and the telescopic end of the second electric cylinder passes through the top of the integrated chassis and is fixedly connected to the top of the frame.
[0014] By adopting the above technical solution, a second electric cylinder is set up to push and pull the frame vertically during extension and retraction, thereby driving the entire lifting frame, load-bearing frame and connecting beams to rise and fall vertically.
[0015] The invention is further configured such that: a liquid pump is fixedly connected to the front side of each of the two containers, the inlet end of the two liquid pumps is fixedly connected to the two containers respectively, and a disinfection nozzle is fixedly connected to the outlet end of the left liquid pump, wherein the disinfection nozzle is fixedly connected to the left side of the pull-out frame.
[0016] By adopting the above technical solution and setting up a liquid pump, it is easy to draw liquid from the container. The left container can store disinfectant such as iodine solution as needed to spray and disinfect the wound when there is no broken skin around the wound, while the right container can store liquids such as saline for cleaning the wound.
[0017] The invention is further configured such that: a plastic tube is fixedly connected to the outlet end of the liquid pump on the right side, a rinsing nozzle is fixedly connected to the side of the plastic tube away from the liquid pump, and a receiving tray is fixedly connected to the bottom of the container.
[0018] By adopting the above technical solution, by setting up a plastic tube, when a single person operates the procedure, the plastic tube can be pulled to the required position. Then, the liquid pump draws up the cleaning fluid and rinses the wound through the rinsing nozzle. The receiving tray is used to collect the cleaning or disinfecting fluid and guide it to the drainage position, reducing the pollution to the surrounding area.
[0019] The present invention is further configured such that: the bandage includes a canvas layer, a gauze layer is fixedly connected to the outside of the canvas layer, a fiber dressing layer is fixedly connected to the outside of the gauze layer, a dressing net is fixedly connected to the outside of the fiber dressing layer, and a protective film is adhered to the outside of the dressing net.
[0020] By employing the above technical solution, a canvas layer is placed on the outermost layer, which can isolate outdoor environmental pollution when bandaging wounds. The gauze layer, as a medical material, has excellent breathability and moisture absorption, and serves as the fixing base for the dressing and the net. The fiber structure of the gauze layer facilitates adhesion and fixation of the net, and it is not easy to fall off. At the same time, the breathable gap between the gauze layer and the canvas allows moisture and blood seepage from the wound area to evaporate, preventing the inner layer from becoming damp and breeding bacteria. The dressing net and fiber dressing layer, which are in direct contact with the wound, can quickly absorb blood moisture, concentrate platelets and clotting factors, and accelerate thrombus formation by contacting and compressing the wound. The protective film can protect the area in contact with the wound when not in use, making it less susceptible to contamination.
[0021] The present invention is further configured such that: a silicone elastic sheet is snapped into the inner side of the card strip, and the bottom of the silicone elastic sheet is in contact with the canvas layer; A buckle is fixedly connected to the side of the canvas layer away from the gauze layer, and a strap is movably connected to the inner side of the buckle. A fastening buckle is fixedly connected to one end of the strap.
[0022] Using the above technical solution, by setting an elastic silicone sheet, when the bandage is clamped inside the clip, the annular elastic silicone sheet is flattened and inserted into the inside of the clip, so that its bottom contacts the bandage, while its top is restricted by the clip and cannot spring back to its original position. The elastic silicone sheet deforms and stores force, pressing the two ends of the bandage against the inside of the clip, preventing the soft bandage from falling off the inside of the clip. At the same time as the fork pulls the bandage downward, the elastic silicone sheet is also pulled downward. When it contacts the edge of the clip, the two ends of the elastic silicone sheet will deform briefly and continue to fall until the bandage contacts the wound. As the fork continues to fall, the elastic silicone sheet will also continue to press down along the contour of the limb until the fork and the elastic silicone sheet are completely separated. At this time, the deformation force of the elastic silicone sheet is released and it adheres to the surface of the limb, thus completing the fixation of the bandage. When the bandage needs to be used away from the camp, the protective film of the bandage should be retained, and the entire bandage should be rolled up and folded to make it approximately cylindrical. Then, the bandage should be passed through the outermost buckle of the cylindrical bandage, and the end of the bandage without a fastening buckle should be inserted into the fastening buckle. At this point, the person can carry the entire roll of bandage directly or carry multiple sets by threading a rope through the hollow part of the cylinder.
[0023] The present invention is further configured such that: the fastening buckle includes a buckle ring, a pressure rod is slidably connected to the inner side of the buckle ring, an annular protrusion is provided on the outer side of the pressure rod, a spring is sleeved on the outer side of the pressure rod, the spring is located between the annular protrusion and the buckle ring, a pivot pin is rotatably connected to the inner side of the buckle ring, a hook is fixedly connected to the bottom of the pivot pin, a torsion spring is fixedly connected to the outer side of the pivot pin, the torsion spring is fixedly connected to the buckle ring on the side near the buckle ring, a push rod is rotatably connected to the outer side of the hook, and the push rod is fixedly connected to the pressure rod on the side near the pressure rod.
[0024] Using the above technical solution, a fastening buckle is used to connect the two ends of the bandage. When bandaging outdoors or when the torso is injured and difficult to bandage through the integrated casing, the protective film can be removed to allow the fiber dressing layer and dressing net to adhere to the injured area. The bandage is then passed through the buckle, wrapped around the wound or limb, and the two ends of the bandage are connected. One end of the bandage is inserted into the inside of the buckle and contacts the arc surface of the hook. During continuous insertion, the hook and the pivot will rotate along the buckle until the bandage is secure. The rebound of the pivot will cause the pivot and the hook to lock onto the outside of the bandage. When the bandage is pulled out, it will be blocked because it is in contact with the sharp end of the hook. When it is necessary to loosen the bandage or adjust the tightness of the bandage, the pressure bar can be pressed down. At this time, the spring is compressed and stored. During the pressure-sensitive process, the push rod connected to it will push the hook and the pivot to rotate, and the sharp surface will disengage from the bandage. At this time, the bandage can be removed.
[0025] (III) Beneficial Effects Compared with the prior art, the present invention provides a portable multifunctional hemostasis and bandaging device suitable for field environments, which has the following beneficial effects: This portable, multi-functional hemostatic and bandaging device, suitable for field environments, can be carried directly to a field camp by its integrated housing. Before use, the pull-out frame can be pulled out from the top of the pull-out frame. Then, the canvas layer of the bandage is facing upwards, and the protective film is removed before inserting it into the inside of the locking strip to complete the pre-loading. The pull-out frame is then reinserted into the pull-out frame. When the limbs need bandaging, the limb can be inserted directly between the curved shell and the pull-out frame, with the wound positioned at the bottom of the pull-out frame. When the photoelectric sensor detects the limb insertion and stops moving, the connecting beam can move downwards until the front opening of the locking fork is located outside the bottom bandage. It then moves forward until it is locked at the top and bottom of the bandage and is pressed down to pull the bottom bandage off the inside of the locking strip. During the continuous pressing, the bandage adheres to the wound site, and as the connecting beam continues to fall, the bandage eventually slides off the inside of the fork, allowing the bandage to fall into the desired position.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1 Please see Figure 1-12 A portable multi-functional hemostasis and bandaging device suitable for field environments includes an integrated chassis 1 and several bandages 2. A pull-out frame 3 is fixedly connected to the front of the integrated chassis 1. A pull-out bracket 4 is inserted into the inner side of the pull-out frame 3. Several clips 5 are fixedly connected to both sides of the inner side of the pull-out bracket 4. The two sides of the bandages 2 are located inside the left and right clips 5, respectively. Containers 6 are fixedly connected to both sides of the bottom of the integrated chassis 1. A sub-frame 7 is fixedly connected to the front of the pull-out frame 3. An arc-shaped shelf 8 is fixedly connected to the bottom of the integrated chassis 1. An arc-shaped shell 9 is fixedly connected to the inner side of the arc-shaped shelf 8. A transparent sheet 10 is fixedly connected to the inner side of the arc-shaped shell 9. A photoelectric sensor 11 is fixedly connected between the arc-shaped shell 9 and the arc-shaped shelf 8. The inner side of the integrated chassis 1 is provided with a connecting beam 12. Two connecting brackets 13 are slidably connected to the inner side of the connecting beam 12. A locking fork 14 is fixedly connected to the bottom of the connecting bracket 13. A silicone elastic sheet 29 is snapped into the inner side of the locking strip 5. The bottom of the silicone elastic sheet 29 is in contact with the canvas layer 201. By using the integrated chassis 1, a single device can be directly carried to a field camp. Before use, the pull-out frame 4 can be pulled out from the top of the pull-out frame 3. Then, the canvas layer 201 of the bandage 2 is turned upwards, and the protective film 205 is removed and inserted into the inside of the clip 5. When the bandage 2 is clipped into the clip 5, the annular silicone elastic sheet 29 is flattened and inserted into the inside of the clip 5 to complete the pre-loading. Then, the pull-out frame 4 is reinserted into the pull-out frame 3. When the limbs need to be bandaged, the limbs can be inserted directly between the curved shell 9 and the pull-out frame 3, with the wound positioned at the bottom of the pull-out frame 4. When the photoelectric sensor 11 senses the limb insertion and stops moving, the connecting beam 12 can move downwards until the front opening of the clip 14 is located outside the bottom bandage 2, and then moves forward. The fork pulls the bandage 2 down from the top of the elastic silicone sheet and the bottom of the bandage 2, pulling it off the inside of the retainer 5 so that its bottom contacts the bandage 2. The top is restricted by the retainer 5 and cannot spring back to its original position. The elastic silicone sheet 29 deforms and stores its force, pressing the two ends of the bandage 31 against the inside of the retainer 5 to prevent the soft bandage 2 from falling off the inside of the retainer 5. As the fork pulls the bandage 2 down, it also pulls the elastic silicone sheet down. When it contacts the edge of the retainer 5, the two ends of the elastic silicone sheet will deform briefly and continue to fall until the bandage 2 contacts the wound. As the fork continues to fall, the elastic silicone sheet will also continue to press down along the contour of the limb until the fork and the elastic silicone sheet are completely separated. At this time, the deformation force of the elastic silicone sheet is released and it adheres to the surface of the limb, completing the fixation of the bandage 2.
[0030] The connecting beam 12 is rotatably connected to a bidirectional lead screw 15, the outer side of which is threaded to the inner side of two connecting frames 13. A servo motor 16 is fixedly connected to the right side of the connecting beam 12, and the output end of the servo motor 16 is fixedly connected to the bidirectional lead screw 15. By setting the bidirectional lead screw, when the servo motor 16 drives the bidirectional lead screw to rotate forward or backward, the two connecting frames 13 are simultaneously extended or brought closer to each other under the limit of the inner side of the connecting beam 12, so as to adjust the relative position of the two forks. Side ears 17 are fixedly connected to both sides of the connecting beam 12, and limit strips 18 are slidably connected to the inner side of the side ears 17. A lifting frame 19 is provided inside the integrated chassis 1, and the front side of the lifting frame 19 is fixed to the limit strip 18. The bottom of the limiting strip 18 is fixedly connected to a load-bearing frame 20. By setting side ears 17 to cooperate with the limiting strip 18, the connecting beam 12 slides along the limiting strip 18 via the side ears 17 when moving horizontally, thus limiting the movement of the connecting beam 12. The lifting mechanism, in conjunction with the load-bearing frame 20, is used to connect the structure and assist in load-bearing. A frame 21 is fixedly connected to the front of the lifting frame 19. A first electric cylinder 22 is fixedly connected to the inner side of the frame 21. The bottom of the frame 21 is fixedly connected to the load-bearing frame 20. The telescopic end of the first electric cylinder 22 is fixedly connected to the connecting beam 12. The frame 21 is used to install the first electric cylinder 22 on the front of the lifting frame 19, and the pushing and pulling of the first electric cylinder 22 drives the connecting beam 12. The integrated chassis 1 is fixedly connected to a second electric cylinder 23 at its top for forward and backward movement. The telescopic end of the second electric cylinder 23 passes through the top of the integrated chassis 1 and is fixedly connected to the top of the frame 21. By setting the second electric cylinder 23, the frame 21 is pushed and pulled vertically during telescopic movement, thereby driving the entire lifting frame 19, the load-bearing frame 20, and the connecting beam 12 to rise and fall vertically. Liquid pumps 24 are fixedly connected to the front of both container tanks 6. The inlet ends of the two liquid pumps 24 are fixedly connected to the two container tanks 6 respectively. The outlet end of the left liquid pump 24 is fixedly connected to a disinfection nozzle 25, which is fixedly connected to the left side of the pull-out frame 3. By setting the liquid pumps 24, it is easy to draw liquid from the container tanks 6. The container can store disinfectant such as iodine solution as needed for spraying disinfection on wounds when there is no broken skin around the wound. The container 6 on the right can store liquids such as saline solution for cleaning the wound. The outlet of the liquid pump 24 on the right is fixedly connected to a plastic tube 26. The side of the plastic tube 26 away from the liquid pump 24 is fixedly connected to a rinsing nozzle 27. The bottom of the container 6 is fixedly connected to a receiving tray 28. By setting the plastic tube 26, when operating by a single person, the plastic tube 26 can be pulled to the desired position. Then the liquid pump 24 draws the cleaning solution and rinses the wound through the rinsing nozzle 27. The receiving tray 28 is used to collect the cleaning or disinfecting solution and guide it to the drainage position to reduce the contamination of the surrounding area.
[0031] The working principle of this embodiment is as follows: Before use, pull out the pull-out frame 4 from the pull-out frame 3, tear off the protective film 205 of the bandage 2 and insert both sides of it into the retaining strip 5 of the pull-out frame 4. At the same time, flatten the annular silicone elastic sheet 29 and insert it into the retaining strip 5, so that its top is limited by the retaining strip 5 and deforms to store force, and its bottom presses against the bandage 2 to prevent it from falling off. After loading multiple bandages 2, insert the pull-out frame 4 back into the pull-out frame 3, and add disinfectant and saline solution to the two side containers 6 respectively for later use. When using, insert the injured limb between the arc-shaped outer shell 9 and the pull-out frame 3 to make the wound suture. The bottom of the pull-out rack 4 remains stationary. The photoelectric sensor 11 between the curved shelf 8 and the curved outer shell 9 senses the limb's state and automatically triggers subsequent actions. The two liquid pumps 24 start synchronously. The left liquid pump 24 draws detoxifying fluid and sprays it onto the skin around the wound via the disinfection nozzle 25. The right liquid pump 24 draws saline solution and adjusts the position of the rinsing nozzle 27 via the flexible and malleable tube 26 to precisely rinse the wound. Waste liquid is collected and diverted by the receiving tray 28 to avoid surrounding contamination. Subsequently, the servo motor 16 drives the bidirectional lead screw 15 inside the connecting beam 12 to rotate. Reversing the direction causes the two connecting frames 13 to unfold or move closer together under the limit of the connecting beam 12. The relative spacing of the clamping forks 14 is adjusted to match limbs of different thicknesses. Then, the first electric cylinder 22 drives the connecting beam 12 to move horizontally forward, and the second electric cylinder 23 drives the connecting beam 12 to move vertically downward, so that the clamping forks 14 are precisely clamped on the top of the silicone elastic sheet 29 and the bottom of the bandage 2. The second electric cylinder 23 continues to press down, pulling the bandage 2 and the silicone elastic sheet 29 out of the clamping strip 5 together. As the clamping forks 14 move down, they gradually conform to the wound and the contour of the limb. When the connecting beam 12 moves, the side ears 17 slide along the limiting strip 18 to ensure accuracy. The force-bearing frame 20 and the lifting frame 19 cooperate to assist in force-bearing and improve stability. After the clamping forks 14 continue to press down until they are completely separated from the silicone elastic sheet 29, the silicone elastic sheet 29 releases its deformation and stores force and tightly adheres to the surface of the limb. Through its own elastic pressure, the bandage 2 is firmly fixed in the wound position, completing the entire automatic bandaging process.
[0032] Example 2 refer to Figure 5-9 A portable multi-functional hemostasis and bandaging device suitable for field environments also includes a bandage 2, wherein the bandage 2 includes a canvas layer 201, a gauze layer 202 is fixedly connected to the outside of the canvas layer 201, a fiber dressing layer 203 is fixedly connected to the outside of the gauze layer 202, a dressing net 204 is fixedly connected to the outside of the fiber dressing layer 203, and a protective film 205 is adhered to the outside of the dressing net 204. By placing the canvas layer 201 on the outermost layer, outdoor environmental pollution can be isolated when bandaging wounds. The gauze layer 202, as a medical material, has excellent breathability and moisture absorption. As the fixing base for the dressing and the net, the fiber structure of the gauze layer 202 facilitates the adhesion and fixation of the net and is not easy to fall off. At the same time, the breathable gap between the gauze layer 202 and the canvas allows moisture and blood seepage from the wound area to evaporate, preventing the inner layer from becoming damp and breeding bacteria. The dressing net 204 and the fiber dressing layer 203, which are in direct contact with the wound, can quickly absorb blood moisture, concentrate platelets and clotting factors, and accelerate thrombus formation. The protective film 205 can protect the area in contact with the wound when not in use, making it less susceptible to contamination.
[0033] The canvas layer 201 is fixedly connected to a buckle 30 on the side away from the gauze layer 202. A strap 31 is movably connected to the inside of the buckle 30. One end of the strap 31 is fixedly connected to a fastening buckle 32. When it is necessary to use the packing strap 2 away from the camp, the protective film 205 should be retained, and the entire packing strap 2 should be rolled up and folded to make it approximately cylindrical. Then, the strap 31 should be passed through the outermost buckle of the cylindrical packing strap 2, and the end of the strap 31 without the fastening buckle 32 should be inserted into the fastening buckle 32. At this time, the person can carry the entire roll of packing strap 2 directly or through the hollow part of the cylinder with a rope. The fastener 32, consisting of multiple sets, includes a buckle 321. A pressure rod 322 is slidably connected to the inner side of the buckle 321. An annular protrusion is provided on the outer side of the pressure rod 322. A spring 323 is sleeved on the outer side of the pressure rod 322, located between the annular protrusion and the buckle 321. A pivot pin 324 is rotatably connected to the inner side of the buckle 321. A hook 325 is fixedly connected to the bottom of the pivot pin 324. A torsion spring 327 is fixedly connected to the outer side of the pivot pin 324. The side of the torsion spring 327 closest to the buckle 321 is fixedly connected to the buckle 321. A push rod 326 is rotatably connected to the outer side of the hook 325. The side of 326 near the pressure bar 322 is fixedly connected to the pressure bar 322. A fastening buckle 32 is used to connect the two ends of the bandage 31. When bandaging outdoors or when the torso is injured and difficult to bandage through the integrated casing 1, the protective film 205 can be removed, allowing the fiber dressing layer 203 and dressing net 204 to adhere to the injured area. The bandage 31 is then passed through the buckle 30, wrapped around the wound or limb, and the ends of the bandage 31 are connected. One end of the bandage 31 is inserted into the inside of the buckle 321 and contacts the arc surface of the hook 325. During continuous insertion, the hook 325 and the pivot pin... 324 will rotate along the buckle 321 until the binding is tight. The rebound of the pivot pin 324 will cause the pivot pin 324 and the hook 325 to be locked on the outside of the strap 31. When the strap 31 is pulled out, it will be blocked because it is in contact with the sharp end of the hook 325. When it is necessary to loosen the strap 31 or adjust the tightness of the binding, the pressure rod 322 can be pressed down. At this time, the spring 323 is compressed and stored. During the pressure-sensitive pressing process, the push rod 326 connected to it will push the hook 325 and the pivot pin 324 to rotate and cause the sharp surface to disengage from the strap 31. At this time, the strap 31 can be removed.
[0034] The working principle of this embodiment is as follows: The outermost canvas layer 201 can isolate outdoor environmental pollution. The inner gauze layer 202 has excellent breathability and moisture absorption, and serves as a base to firmly bond the dressing net 204. It also forms a breathable gap with the canvas layer 201, which can evaporate moisture and oozing from the wound area and prevent dampness from breeding bacteria. The fiber dressing layer 203 and the dressing net 204 can quickly absorb blood moisture, concentrate platelets and clotting factors to accelerate thrombus formation. When not in use, the outer protective film 205 ensures the sterility of the wound contact area. The canvas layer 201 is connected to the buckle 30 and the strap 31 on the outside. One end of the strap 31 is equipped with a fastening buckle 32. When used away from the camp, the protective film 205 is retained, the bandage 2 is rolled and folded into a tube shape, the strap 31 is passed through the outermost buckle 30 of the tube bandage 2, and then the end of the strap 31 without the fastening buckle 32 is inserted into the fastening buckle 32. It can be carried alone or in multiple sets by ropes. When manually bandaging, tear off the protective film 205, attach the fiber dressing layer 203 and dressing net 204 to the wound, pass the bandage 31 through the buckle 30 around the torso or limb, and then connect the ends. Insert one end of the bandage 31 into the buckle 321 of the fastening buckle 32 and contact the arc surface of the hook 325. Continuing to insert will cause the hook 325 and the pivot pin 324 to rotate along the buckle 321. The torsion spring 327 stores and rebounds, causing the hook 325 to lock on the outside of the bandage 31 to achieve self-locking and prevent the bandage 31 from coming off due to force. When it is necessary to adjust the tightness or remove the bandage, press down the pressure rod 322 to compress the spring 323. The pressure rod 322 drives the hook 325 and the pivot pin 324 to rotate through the push rod 326, so that the sharp end of the hook 325 disengages from the bandage 31. The bandage 31 can then be pulled out to complete the adjustment or removal, realizing fast and secure manual bandaging outdoors without equipment assistance.
