Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical emergency technology, and in particular to a leg fracture fixation splint. Background Technology
[0002] Currently, in emergency treatment of leg fracture patients in natural disasters or other outdoor environments, ensuring stable fixation of the fracture site is crucial to effectively prevent secondary injuries during transport. However, the splints currently in use are single pieces, often requiring two people to work together during emergency treatment: one to adjust the splint's position and the other to wrap the bandage. This makes the splint fixation process cumbersome, prolonging the patient's rescue time. Overly tight splints can compress blood vessels after the fracture, while overly loose splints can lead to ineffective fixation.
[0003] Therefore, it is necessary to design a leg fracture fixation splint that can be quickly assembled and disassembled, and has the function of changing the clamping area. Utility Model Content
[0004] To overcome the shortcomings of current splints, which often require two people to work together during emergency treatment—one to adjust the splint position and the other to wrap the bandage—making the splint fixation process cumbersome and prolonging the patient's rescue time, the technical problem to be solved is to provide a leg fracture fixation splint.
[0005] A leg fracture fixation splint includes a splint, a rotating component, fixation blocks, long straps, short straps, square sleeves, hook and loop fasteners, and fixation components. The rotating component is located between the bent portions of two splints. Fixation blocks are spaced apart on the sidewalls of the two splints that are far from each other. Long straps are symmetrically arranged on the top and bottom of the fixation blocks of one splint, and short straps are symmetrically arranged on the top and bottom of the fixation blocks of the other splint. Square sleeves are provided on the short straps. Hook and loop fasteners are provided at the end of the side of the long strap that is far from the fixation block, and hook and loop fasteners are provided in the middle of the side of the long strap. Fixation components that can wrap around the fracture site are provided on each splint.
[0006] As a further preferred embodiment, the rotating assembly includes a locking shaft, a fixed seat, a moving rod, a pull rod, and an elastic element. The bent portions of the two clamping plates are staggered and connected in series via the locking shaft. A fixed seat is provided at the end of the locking shaft. Circular holes are symmetrically opened on the locking shaft, and corresponding circular holes are opened at the bent portions of the clamping plates. A moving rod is slidably arranged at the circular hole position of the locking shaft. A pull rod is arranged between the moving rods. An elastic element is sleeved on the moving rod. One end of the elastic element is connected to the pull rod, and the other end of the elastic element is connected to the locking shaft.
[0007] As a further preferred embodiment, the fixing component includes a disc, a connector, a connecting air tube, an airbag, and a connecting pipe. The clamping plate has spaced mounting holes, and an airbag is spaced within each mounting hole. A disc is mounted on a fixing block at a bend in the clamping plate away from the center. A connector is symmetrically embedded in the disc away from the center, and a vent valve is mounted on the connector. Connecting air tubes are symmetrically arranged on the upper and lower parts of the clamping plate. Each adjacent airbag is connected to a connecting pipe, and the connecting pipes on adjacent airbags are staggered vertically. The connecting air tubes are connected to the nearest connecting pipe.
[0008] As a further preferred embodiment, it also includes a jet pipe, an injection pipe, and a connecting pipe. Jet pipes are symmetrically arranged on the inner side of the clamping plate, and an injection pipe is embedded in the center of the disc. The injection pipe is connected to the connecting pipe, and the two ends of the connecting pipe are respectively connected to the upper and lower jet pipes.
[0009] As a further preferred embodiment, it also includes locking blocks and support plates, with locking blocks spaced apart at the top of the clamping plate, and a support plate engaging between two locking blocks.
[0010] As a further preferred option, the plywood is a curved plate made of rigid plastic.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. This device has a simple structure, facilitating rapid operation by medical personnel at the emergency scene. By simply pulling the lever, rotating the clamps, and releasing the lever, the two clamps can quickly clamp and immobilize the leg. The device is designed with an airbag and interchangeable connectors, allowing medical personnel to adjust the clamping area according to the leg injury. By connecting an external inflation device to different connectors and controlling the deflation valve, different parts of the leg can be supported and immobilized, improving the effectiveness of emergency treatment.
[0013] 2. An external cold air input device allows cold air to be sprayed onto the leg through a jet nozzle, helping to reduce blood flow to the injured area and decrease swelling. Simultaneously, the cold air does not directly contact the skin, avoiding the risk of frostbite. To prevent injury to the leg due to splint deformation caused by accidental impact, a support plate and locking block structure is designed. By locking the support plate onto the locking block, additional support is provided, enhancing the stability and safety of the device and protecting the injured leg from further injury.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Example 1: A leg fracture fixation splint, such as Figure 1-5As shown, the assembly includes a clamping plate 1, a rotating component 2, a fixing block 3, a long strap 4, a short strap 5, a square sleeve 6, a hook and loop fastener 7, a loop fastener 71, and a fixing component 8. The clamping plate 1 is an arc-shaped plate made of hard plastic. The rotating component 2 is located between the bent parts of the two clamping plates 1. The rotating component 2 includes a locking shaft 21, a fixing seat 22, a moving rod 23, a pull rod 24, and an elastic element 25. The bent parts of the two clamping plates 1 are staggered and connected in series by the locking shaft 21. The fixing seat 22 is located at the end of the locking shaft 21. The locking shaft 21 has symmetrically symmetrically opened round holes, and the bent part of the clamping plate 1 has a corresponding round hole. A moving rod 23 is slidably installed at the round hole position of the locking shaft 21. A pull rod 24 is installed between the moving rods 23. An elastic element 25, which is a tension spring, is sleeved on the moving rod 23. One end of the elastic element 25 is connected to the pull rod 24, and the other end of the elastic element 25 is connected to the locking shaft 21. Fixing blocks 3 are spaced apart on the side walls of the two clamping plates 1 that are far apart from each other. The fixing blocks 3 of one clamping plate 1 are symmetrically arranged with long... The splint 1 has symmetrically arranged short straps 5 on its upper and lower fixing blocks 3, with square sleeves 6 on each short strap 5. The square sleeves 6 are 3cm wide. The side of the long strap 4 away from the fixing block 3 has a Velcro hook surface 7, and the middle side of the long strap 4 has a Velcro rough surface 71. The splint 1 is equipped with a fixing component 8 that can wrap around the patient's fracture site. The fixing component 8 includes a disc 81, a connector 82, a connecting trachea 83, an air bag 84, and a connecting tube 85. The splint 1 has spaced mounting holes. Airbags 84 are spaced apart in the mounting holes. Each airbag 84 is 2cm wide. A disc 81 is installed on the fixing block 3 at the bend of the clamping plate 1, which is far from the center. A connector 82 is symmetrically embedded on the disc 81, which is far from the center. The connector 82 is equipped with a vent valve, which is a manual vent valve. Connecting air pipes 83 are symmetrically arranged on the upper and lower parts of the clamping plate 1. Each adjacent airbag 84 is connected to a connecting pipe 85. The connecting pipes 85 on adjacent airbags 84 are staggered vertically. The connecting air pipe 83 is connected to the nearest connecting pipe 85.
[0022] In emergency situations, this device is brought to the scene. Medical personnel pull the lever 24, which causes the moving rod 23 to disengage from the circular hole of the clamp 1, stretching the elastic element 25. One of the clamps is then rotated 180°, symmetrically aligning the two clamps 1 with their arc surfaces. The lever 24 is then released, causing the elastic element 25 to reset the moving rod 23, which then inserts into the circular hole of the clamp 1, thus fixing the two clamps 1 in place. The clamps 1 are then secured to both sides of the leg, with the foot contacting the bent portion of the clamp 1. The arc surfaces of the clamps 1 are fixed to both sides of the leg. The hook and loop fastener 7 of the long strap 4 is then passed through the adjacent square sleeve 6 and attached to the hook and loop fastener 71, thus securing the leg. Finally, the medical personnel connect the external inflation device to one of the connectors 82 on the disc 81. Inflation is performed by connecting head 82, which is equipped with a one-way valve for one-way air intake. Gas enters the airbag 84 through connecting pipe 83 and connecting tube 85, thereby supporting and fixing the leg. When it is necessary to change the clamping area, the external inflation device is connected to another connecting head 82 in the disc 81 for inflation, and the deflation valve of the previous connecting head 82 is opened to release the air, thus changing the clamping area of the leg. This device has a simple structure, which facilitates quick fixation of the leg and allows the clamping area to be changed at any time according to the situation.
[0023] Example 2: Based on Example 1, such as Figure 5 As shown, it also includes a jet pipe 9, an injection pipe 10, and a connecting pipe 11. The jet pipes 9 are symmetrically arranged on the inner side of the clamp 1. The injection pipe 10 is embedded in the middle of the disc 81. The injection pipe 10 is connected to the connecting pipe 11. The two ends of the connecting pipe 11 are connected to the upper and lower jet pipes 9 respectively. Depending on the emergency situation, if cold compress is needed, it can be connected to the injection pipe 10 through an external cold air input device. The cold air enters the jet pipe 9 through the connecting pipe 11 and is then sprayed onto the leg to reduce blood flow to the injured area, thereby reducing swelling and avoiding direct contact with the skin to prevent frostbite. The spraying time should not be too long. Generally, the cold air is intermittently input through the external cold air input device, and the time generally does not exceed 20 minutes.
[0024] like Figure 1 As shown, it also includes a locking block 12 and a support plate 13. The support plate 13 has symmetrical locking holes, and the top of the clamping plate 1 is provided with locking blocks 12 at intervals. The support plate 13 is locked between two locking blocks 12. In order to prevent the clamping plate 1 from deforming due to accidental impact and causing injury to the legs, it is necessary to further fix the clamping. The support plate 13 is locked onto the locking block 12 to provide support.
