Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to an adjustable limb fixation device for emergency care. Background Art
[0002] When people's bones are injured, medical staff need to use a medical limb fixation device to fix the patient during treatment so that the wound can heal better. With the development of medicine, splint fixation has gradually become a common method, and wooden splints are widely used. Doctors began to select appropriate splint shapes and fixation methods according to different parts and fracture types. For example, straight splints are used for upper limb fractures, and long splints are used for lower limb fractures, etc., which improves the fixation effect and stability.
[0003] When a doctor uses a fixation device to fix the injured arm or leg of a patient, the long-term immobility of the arm or leg easily causes poor blood circulation in the injured part of the patient, resulting in numbness in the fixed limb of the patient. Summary of the Invention
[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: an adjustable limb fixation device for emergency care, including a fixation component for fixing the limb, a rotating member is rotatably connected to the outside of the fixation component, and an adjustment component is fixedly connected to the end of the rotating member away from the fixation component; Among them, the fixing component includes arc plates. There are two arc plates, which are symmetrically arranged. Through holes are provided on the outer sides of the arc plates. The through holes are hexagonal holes. Providing through holes on the outer sides of the arc plates can effectively reduce the weight of the arc plates. And the hexagonal hole structure removes some materials while ensuring the overall strength of the arc plates. At the same time, the hexagonal holes can serve as channels for air circulation, enhancing the air permeability of the arc plates. When in hot weather or when the patient's limb moves a little more, air can enter and exit through the hexagonal holes, and the sweat and heat on the skin surface can be dissipated through these holes, keeping the skin surface relatively dry, reducing skin problems caused by local dampness and stuffiness. There are multiple through holes, and the multiple through holes are evenly distributed on the arc plates. An extension block is fixedly connected to the outer side of the arc plate. A groove is provided at one end of the extension block close to the arc plate. Two round rods are arranged inside the groove. A middle part of the round rods is fixedly connected with an elastic band. Two ends of the elastic band are respectively connected to the two round rods. When a patient has a fracture, it is necessary to fix the patient's limb, so that the patient's arm passes through the two arc plates. By adjusting the position of the round rods in the fixing frames on the outer sides of the arc plates, the patient's limb can be fixed. At this time, the patient's limb is fixed in an alternating manner by the two arc plates and the two elastic bands. Since the elastic band has a certain elasticity, this fixing method can well adapt to the shapes and sizes of different limb parts. When it connects the two arc plates to fix the limb, it can automatically adjust the tightness according to the thickness of the limb. At the same time, the elastic band can evenly distribute the pressure on the surface of the limb during the fixing process. The elasticity of the elastic band enables it to evenly disperse the pressure generated by the two arc plates on the limb when tightened. The uniform pressure helps to reduce the risk of displacement of the fracture ends, and can also avoid damaging soft tissues such as the skin and muscles due to excessive local pressure, or poor blood circulation caused by uneven pressure, reducing the occurrence of complications caused by fixation, such as pressure sores and aggravated limb swelling. The elastic band is located at the interval between the two arc plates. Fixing frames are fixedly connected to the outer sides of the arc plates. There are multiple fixing frames. Two fixing frames are grouped together. A group of fixing frames is symmetrically arranged with the round rods as the center.
[0005] Preferably, a frame body is slidably connected to the outer side of the arc plate. The two arc plates are symmetrically arranged with the frame body as the center. The extension blocks are symmetrically arranged at both ends of the arc plates. A notch is provided on the inner wall of the extension block close to the groove. The elastic band passes through the extension block through the notch. By adjusting the position of the round rods in the fixing frames on the outer sides of the arc plates, under the elastic force of the elastic band, the two arc plates move towards the middle, causing the square rods to slide inside the sliding grooves, thereby adjusting the interval between the two arc plates. Through the relative sliding between the square rods and the sliding grooves, a guiding effect is achieved. A square rod is fixedly connected to one end of the extension block close to the elastic band. A sliding groove is provided on the outer side of the extension block far from the arc plate. There are multiple square rods, and the square rods and the sliding grooves are alternately arranged.
[0006] Preferably, the adjusting assembly includes an intermediate plate. A connecting rod is fixedly connected to one side of the intermediate plate close to the fixing plate. The connecting rod is located inside the annular groove. One end of the connecting rod away from the intermediate plate is fixedly connected to the rotating member. By providing the fixing assembly, the rotating member and the adjusting assembly to fix both sides of the joint, the limb can be fixed from different angles. Since the fixing assembly can rotate between the rotating member and the adjusting assembly, they can adjust the fixing angle according to the specific condition of the limb injury. This multi-angle fixing method can better control the position of the limb, prevent the displacement of the fracture end or further injury of the joint. By fixing both sides with the fixing assembly and the adjusting assembly, it is convenient for medical staff to adjust the tightness of the fixing assembly and the adjusting assembly respectively according to the specific condition of the patient for limbs with different swelling degrees. For different injury types and recovery stages, the fixing angle or force on both sides can also be flexibly changed to achieve a personalized fixing plan. A middle rod is slidably connected to the outside of the rotating member. A square plate is fixedly connected to the outside of the middle rod. An L-shaped plate is fixedly connected to one end of the square plate close to the fixing assembly. The L-shaped plate is located inside the trapezoidal groove. A guiding rod is fixedly connected to one side of the square plate close to the intermediate plate. A spring plate is slidably connected to the outside of the guiding rod. A bottom plate is fixedly connected to the square plate away from the spring plate. An elastic cord is fixedly connected to the outside of the bottom plate. The limb of the patient passes through the bottom plate and the spring plate. By utilizing the elastic property of the elastic cord, the bottom plates and the spring plates on both sides fix the limb. The two ends of the elastic cord are respectively connected to the bottom plate and the spring plate. The middle rod penetrates through the rotating member. One end of the middle rod away from the square plate is fixedly connected to a magnet. The number of magnets is two. The magnetism between the two magnets is opposite. An elastic plate is fixedly connected to the outside of the magnet.
[0007] The rotating member includes a turntable. The turntable is located at the interval between the two square plates. The turntable is fixedly connected to the connecting rod. An inner cavity is formed inside the turntable. A circular groove is formed on the outside of the turntable.
[0008] The L-shaped plate is fixed to the locking plate by the L-shaped plate, and the locking plate is fixed to the locking plate by the L-shaped plate. The fixing rod is located inside the circular groove on the outside of the turntable. When the patient rotates through the turntable, a certain range of movement is allowed at the joint, which is beneficial to maintaining the mobility of the joint. In some early stages of rehabilitation, the patient can perform a small range of joint movement with the assistance of the fixing device to promote the circulation of synovial fluid. An annular groove is provided on the outer side of the fixing plate away from the circular ring, and a sliding groove is provided on the end of the fixing plate away from the circular ring. A sliding block is slidably connected to the inner wall of the sliding groove, and an arc block is fixedly connected to the end of the sliding groove away from the sliding groove. A fixing rod is fixedly connected to the outer side of the arc block. By setting the arc block, the rotation range of the turntable is limited to avoid excessive joint movement, which may cause serious consequences such as displacement of fracture ends and further tearing of soft tissue, and can ensure that the fixing device effectively fixes the injured limb. The fixing rod is located at the end of the fixing plate away from the circular ring, the arc block is a quarter-circular frame, and a spring is fixedly connected to the end of the arc block away from the fixing rod, and the end of the spring away from the arc block is fixedly connected to the fixing plate.
[0009] The present invention provides an adjustable limb fixation device for emergency nursing, which has the following beneficial effects: 1. The adjustable limb fixation device for emergency nursing can evenly disperse the pressure exerted by the two arc plates on the limbs when tightened through the elasticity of the elastic band. The uniform pressure helps to reduce the risk of displacement of the fracture ends, and can also avoid damage to soft tissues such as skin and muscles due to excessive local pressure, or poor blood circulation due to uneven pressure, thereby reducing complications caused by fixation.
[0010] 2. The adjustable limb fixation device for emergency nursing adopts a fixing method that alternately sets two arc plates and two elastic bands. Since the elastic bands have a certain elasticity, this fixing method can adapt well to the shapes and sizes of different limb parts. When it connects the two arc plates to fix the limbs, it can automatically adjust the tightness according to the thickness of the limbs.
[0011] III. For the adjustable limb fixation device for emergency care, by setting through holes on the outer side of the arc plate, the weight of the arc plate can be effectively reduced. Moreover, under the premise of ensuring the overall strength of the arc plate, the hexagonal hole structure removes some materials, and at the same time, the hexagonal holes can serve as channels for air circulation, enhancing the air permeability of the arc plate.
[0012] IV. For the adjustable limb fixation device for emergency care, by fixing both sides of the fixing component and the adjusting component, it is convenient for medical staff to adjust the tightness of the fixing component and the adjusting component respectively according to the specific situation of the patient for limbs with different degrees of swelling. For different types of injuries and recovery stages, the fixing angles or forces on both sides can also be flexibly changed to achieve a personalized fixation plan. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
[0016] The first embodiment is as Figures 1 to 6 shown. The present invention provides a technical solution: an adjustable limb fixation device for emergency care, including a fixation component 1 for fixing a limb. A rotating member 2 is rotatably connected to the outside of the fixation component 1, and an adjusting component 3 is fixedly connected to the end of the rotating member 2 away from the fixation component 1; Among them, the fixing component 1 includes arc plates 11. There are two arc plates 11, and the two arc plates 11 are symmetrically arranged. Through holes 14 are formed on the outer side of the arc plates 11. The through holes 14 are hexagonal holes. Arranging the through holes 14 on the outer side of the arc plates 11 can effectively reduce the weight of the arc plates. And under the premise of ensuring the overall strength of the arc plates, the hexagonal hole structure removes some materials. At the same time, the hexagonal holes can serve as channels for air circulation, enhancing the air permeability of the arc plates 11. When in hot weather or when the patient's limb moves a little more, air can enter and exit through the hexagonal holes, and the sweat and heat on the skin surface can be dissipated through these holes, keeping the skin surface relatively dry, reducing skin problems caused by local dampness and stuffiness. There are multiple through holes 14, and the multiple through holes 14 are evenly distributed on the arc plates 11. A prolonging block 15 is fixedly connected to the outer side of the arc plates 11. A groove 110 is formed at one end of the prolonging block 15 close to the arc plates 11. A round rod 16 is arranged inside the groove 110. There are two round rods 16. A elastic band 17 is fixedly connected to the middle of the round rods 16. The two ends of the elastic band 17 are respectively connected to the two round rods 16. When a patient has a fracture, it is necessary to fix the patient's limb, so that the patient's arm passes through the two arc plates 11. By adjusting the position of the round rods 16 in the fixing frame 13 on the outer side of the arc plates 11, the patient's limb can be fixed. At this time, the patient's limb is fixed in an alternating manner by the two arc plates 11 and the two elastic bands 17. Since the elastic band 17 has a certain elasticity, this fixing method can well adapt to the shapes and sizes of different limb parts. When it connects the two arc plates to fix the limb, it can automatically adjust the tightness according to the thickness of the limb. At the same time, the elastic band 17 can evenly distribute the pressure on the surface of the limb during the fixing process. The elasticity of the elastic band 17 enables it to evenly disperse the pressure generated by the two arc plates 11 on the limb when tightened. The uniform pressure helps reduce the risk of displacement of the fracture ends, and can also avoid damaging soft tissues such as the skin and muscles due to excessive local pressure, or blood circulation disorders caused by uneven pressure, reducing the occurrence of complications caused by fixation, such as pressure sores and aggravated limb swelling. The elastic band 17 is located at the interval between the two arc plates 11. Multiple fixing frames 13 are fixedly connected to the outer side of the arc plates 11. Two fixing frames 13 form a group, and a group of fixing frames 13 are symmetrically arranged with the round rod 16 as the center.
[0017] A frame body 12 is slidably connected to the outer side of the arc plate 11. The two arc plates 11 are symmetrically arranged with the frame body 12 as the center. Extension blocks 15 are symmetrically arranged at both ends of the arc plate 11. A notch 111 is formed in the inner wall of the extension block 15 close to the groove 110. The elastic band 17 passes through the extension block 15 through the notch 111. By adjusting the position of the adjusting round rod 16 in the fixed frame 13 on the outer side of the arc plate 11, under the elastic force of the elastic band 17, the two arc plates 11 move towards the middle, so that the square rod 19 slides inside the sliding groove 18, thereby adjusting the interval between the two arc plates 11. Through the relative sliding between the square rod 19 and the sliding groove 18, a guiding function is achieved. One end of the extension block 15 close to the elastic band 17 is fixedly connected to the square rod 19. A sliding groove 18 is formed in the outer side of the extension block 15 away from the arc plate 11. The number of the square rods 19 is multiple, and the square rods 19 and the sliding grooves 18 are arranged alternately.
[0018] Second embodiment, on the basis of the first embodiment, please refer to Figures 7 to 8 As shown, the adjusting assembly 3 includes an intermediate plate 35. One side of the intermediate plate 35 close to the fixing plate 122 is fixedly connected with a connecting rod 37. The connecting rod 37 is located inside the annular groove 129. One end of the connecting rod 37 away from the intermediate plate 35 is fixedly connected with the rotating member 2. By arranging the fixing assembly 1, the rotating member 2 and the adjusting assembly 3 to fix both sides of the joint, the limb can be fixed from different angles. Since the fixing assembly 1 can rotate between the rotating member 2 and the adjusting assembly 3, they can adjust the fixing angle according to the specific situation of the limb injury. This multi-angle fixing method can better control the position of the limb and prevent the displacement of the fracture end or further damage to the joint. By the way of fixing both sides of the fixing assembly 1 and the adjusting assembly 3, it is convenient for medical staff to adjust the tightness of the fixing assembly 1 and the adjusting assembly 3 according to the specific situation of the patient for limbs with different swelling degrees. For different injury types and recovery stages, the fixing angles or forces on both sides can also be flexibly changed to realize a personalized fixing scheme. An intermediate rod 38 is slidably connected to the outer side of the rotating member 2. A square plate 31 is fixedly connected to the outer side of the intermediate rod 38. One end of the square plate 31 close to the fixing assembly 1 is fixedly connected with an L-shaped plate 32. The L-shaped plate 32 is located inside the trapezoidal groove 123. One side of the square plate 31 close to the intermediate plate 35 is fixedly connected with a guiding rod 311. A spring plate 34 is slidably connected to the outer side of the guiding rod 311. A bottom plate 33 is fixedly connected to the square plate 31 away from the spring plate 34. An elastic cord 36 is fixedly connected to the outer side of the bottom plate 33. The limb of the patient passes through the bottom plate 33 and the spring plate 34. By using the elastic performance of the elastic cord 36, the two bottom plates 33 and the spring plates 34 fix the limb. The two ends of the elastic cord 36 are respectively connected to the bottom plate 33 and the spring plate 34. The intermediate rod 38 passes through the rotating member 2. One end of the intermediate rod 38 away from the square plate 31 is fixedly connected with a magnetic block 39. The number of the magnetic blocks 39 is two. The magnetisms between the two magnetic blocks 39 are opposite. An elastic plate 310 is fixedly connected to the outer side of the magnetic block 39.
[0019] The rotating member 2 includes a turntable 21. The turntable 21 is located at the interval between the two square plates 31. The turntable 21 is fixedly connected to the connecting rod 37. An inner cavity 22 is formed inside the turntable 21, and a circular groove 23 is formed on the outer side of the turntable 21.
[0020] For the third embodiment, on the basis of the first and second embodiments, please refer to Figure 9 As shown, the frame body 12 includes a circular ring 121. A fixing plate 122 is fixedly connected to the side of the circular ring 121 close to the arc plate 11. The fixing plates 122 are symmetrically arranged with the arc plate 11 as the center. The fixing plates 122 are located at the interval between the two arc plates 11. An inclined groove 1210 is formed on the side of the fixing plate 122 close to the extension block 15. The square rod 19 is slidably connected to the fixing plate 122. The square rod 19 penetrates through the fixing plate 122. A trapezoidal groove 123 is formed on the outer side of the fixing plate 122. In the initial state, the L-shaped plate 32 is located inside the trapezoidal groove 123. At this time, the square plate 31 is fixed by the L-shaped plate 32. At this time, the fixing assembly 1 and the adjusting assembly 3 cannot be adjusted in angle through the rotating member 2, and are in a non-rotatable fixing mode, so that the fracture ends can be accurately fixed at the reset position, avoiding the fracture ends from being displaced again due to the rotation of the limb. When an external force is applied to the rotating member 2 and the L-shaped plate 32, the square plate 31 is stressed to drive the intermediate rod 38 to move away from the rotating member 2, so that the L-shaped plate 32 moves away from the inside of the trapezoidal groove 123, so that the connecting rod 37 drives the rotating member 2 to slide downward inside the annular groove 129. At the same time, by using the mutual suction force between the two magnetic blocks 39, the square plate 31 is reset. Subsequently, the fixing rod 128 is located inside the circular groove 23 on the outer side of the turntable 21. When the patient rotates through the turntable 21, a certain range of activities is allowed at the joint, which is beneficial to maintaining the mobility of the joint. In some early rehabilitation stages, the patient can perform small-range joint activities with the assistance of the fixing device to promote the circulation of joint fluid. An annular groove 129 is formed on the outer side of the fixing plate 122 away from the circular ring 121. A sliding groove 124 is formed at one end of the fixing plate 122 away from the circular ring 121. A slider 126 is slidably connected to the inner wall of the sliding groove 124. One end of the slider 126 away from the sliding groove 124 is fixedly connected to an arc block 125. A fixing rod 128 is fixedly connected to the outer side of the arc block 125. By providing the arc block 125, the rotation range of the turntable 21 is restricted, avoiding serious consequences such as fracture end displacement and further soft tissue tearing that may be caused by excessive joint activity, and ensuring the effective fixation of the fixing device on the injured limb. The fixing rod 128 is located at one end of the fixing plate 122 away from the circular ring 121. The arc block 125 is a quarter-round frame. One end of the arc block 125 away from the fixing rod 128 is fixedly connected to a spring 127. One end of the spring 127 away from the arc block 125 is fixedly connected to the fixing plate 122.
[0021] During use, when a patient has a fracture, it is necessary to fix the patient's limb. The patient's arm passes through two arc plates 11. By adjusting the position of the round rod 16 in the outer fixing frame 13 of the arc plate 11, the patient's limb can be fixed. At this time, the patient's limb is fixed in an alternating manner by two arc plates 11 and two elastic bands 17. Since the elastic band 17 has a certain elasticity, this fixing method can well adapt to the shapes and sizes of different limb parts. When it connects the two arc plates to fix the limb, it can automatically adjust the tightness according to the thickness of the limb. At the same time, the elastic band 17 can evenly distribute the pressure on the surface of the limb during the fixing process. The elasticity of the elastic band 17 enables it to evenly disperse the pressure generated by the two arc plates 11 on the limb when tightened. The uniform pressure helps to reduce the risk of displacement of the fracture ends.
[0022] The L-shaped plate 32 is located inside the trapezoidal groove 123. At this time, the square plate 31 is fixed by the L-shaped plate 32. At this time, the fixing assembly 1 and the adjusting assembly 3 cannot be adjusted in angle through the rotating member 2, and are in a non-rotatable fixing method, so that the fracture ends can be accurately fixed at the reset position, avoiding the fracture ends from being displaced again due to the rotation of the limb. When an external force is applied to the rotating member 2 and the L-shaped plate 32, the square plate 31 is stressed and drives the middle rod 38 to move away from the rotating member 2, so that the L-shaped plate 32 moves away from the inside of the trapezoidal groove 123, causing the connecting rod 37 to drive the rotating member 2 to slide downward inside the annular groove 129. At the same time, by using the mutual suction force between the two magnetic blocks 39, the square plate 31 is reset. Subsequently, the fixing rod 128 is located inside the circular groove 23 on the outside of the turntable 21. When the patient rotates through the turntable 21, a certain range of movement is allowed at the joint, which is beneficial to maintaining the mobility of the joint. In some early rehabilitation stages, the patient can perform small-range joint activities with the assistance of the fixing device to promote the circulation of synovial fluid.
