Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a rapid fixation traction frame for fractures in emergency rescue. Background Technology

[0002] The main purpose of traction after a fracture is to help reduce the fracture, relieve pain, and prevent secondary injury by applying external force. Traction uses continuous and stable tension to counteract muscle contraction and soft tissue spasm, gradually aligning the fracture ends while reducing the risk of nerve and blood vessel compression, thus creating conditions for subsequent treatments (such as surgery or plaster cast immobilization). Currently, when applying traction to a fracture site, the traction force needs to be determined based on the patient's weight. However, in emergency rescue at the fracture site, patient weight information is often unavailable, yet rapid emergency rescue is required. Existing traction frames are often not suitable for rapid emergency rescue and can only be adjusted based on specific values. Without specific traction force values, it is impossible to determine whether the traction force is within a safe range, thus preventing the application of traction within a safe range and potentially leading to traction errors due to insufficient or excessive force.

[0003] According to the multi-dimensional angle adjustable fracture three-dimensional reduction and traction device disclosed in Chinese Publication No. CN120814948A, it includes a leg support mechanism for supporting the patient's lower leg and fixing the knee end; and a traction mechanism for traction of the patient's calcaneus. In this invention, the height of the telescopic support assembly is limited by the wedge-shaped surface abutting against the ball end of the anti-fall micro-adjustment component, preventing it from falling, thus achieving position locking. Then, the depth of entry into and away from the inner cavity of the insertion sleeve is adjusted by the thread of the anti-fall micro-adjustment component.

[0004] The aforementioned application can prevent a sudden drop during height adjustment of the traction frame, which could cause secondary injury to the patient. However, this type of traction frame cannot be used for emergency rescue at the fracture site. Furthermore, without a specific traction force value, it is impossible to apply traction to the patient within a reasonable and safe range, which could affect emergency treatment of fracture patients or lead to traction errors. Therefore, to address this problem, this application provides an emergency rescue fracture site rapid fixation traction frame to meet the needs. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a rapid fixation traction frame for fractures in emergency rescue. Through the traction component, reasonable and safe traction can be applied to different types of patients to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An emergency fracture on-site rapid fixation traction frame includes a support frame. A lower leg fixation member is fixedly connected to the inner side of the support frame. A lower leg Velcro strap is fixedly connected to the outer side of the lower leg fixation member. A connecting strap is fixedly connected to one side of the lower leg Velcro strap. A thigh fixation member is fixedly connected to one end of the connecting strap. A thigh Velcro strap is fixedly connected to the outer side of the thigh fixation member. An arc-shaped crossbar is fixedly connected to the inner side of the support frame. The arc-shaped crossbar has an arc-shaped profile. A traction assembly is provided at one end of the support frame. The traction assembly includes an end plate fixedly connected to one end of the support frame. An adjusting stud is threaded internally connected to the end plate. A rotating handle is fixedly connected to one end of the adjusting stud. A fitting is rotatably sleeved at the end of the adjusting stud away from the rotating handle.

[0007] In a preferred embodiment, a heavy-weight position indicator is fixedly connected to one end of the kit. Two first adjusting bolts are inserted into the interior of the heavy-weight position indicator. The two first adjusting bolts are arranged symmetrically on the axis. A first nut is threaded onto the outer side of each of the two first adjusting bolts. A first connecting chain is fixedly connected to the side of the heavy-weight position indicator away from the kit.

[0008] In a preferred embodiment, a small weight indicator is sleeved on one end of the first connecting chain, and two second adjusting bolts are inserted inside the small weight indicator. The two second adjusting bolts are arranged symmetrically on the axis, and a second nut is threaded to the outer side of each of the two second adjusting bolts. The second connecting chain is sleeved on the side of the small weight indicator away from the first connecting chain.

[0009] In a preferred embodiment, a foot limiting plate is provided on the inner side of the arc-shaped crossbar, and a foot bracket is fixedly connected to the bottom of the foot limiting plate. The bottom contour of the foot bracket is adapted to the inner contour of the arc-shaped crossbar.

[0010] In a preferred embodiment, a foot Velcro strap is fixedly connected to one side of the foot limiting plate, a foot fixing member is fixedly connected to the inside of the foot Velcro strap, a traction strap is fixedly connected to one side of the foot fixing member, and the second connecting chain is sleeved on one side of the traction strap.

[0011] In a preferred embodiment, one end of the bracket is rotatably connected to a connecting screw sleeve, the inner side of the connecting screw sleeve is threadedly connected to a hanger, and the inner side of the hanger is fixedly connected to a reinforcing rod.

[0012] In a preferred embodiment, a support assembly is provided on the outer side of the bracket. The support assembly includes a rotating head rotatably connected to one side of the bracket. A support frame is fixedly connected to the outer side of the rotating head, and a foot post is fixedly connected to one end of the support frame.

[0013] In a preferred embodiment, a shaft is fixedly connected to one side of the bracket, the rotating head is rotatably connected to the outside of the shaft, a fixed column is slidably connected to the outside of the shaft, and the fixed column is slidably connected to the inside of the rotating head.

[0014] In a preferred embodiment, the support components are configured in two groups, and the two groups of support components are arranged in an axisymmetric manner.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention, by setting up a traction component, can classify patients into two categories based on their body shape using small-weight and large-weight positioning components. The deformation of these components ensures that the traction force is within the allowable range, facilitating initial traction for fracture patients during emergency treatment. This helps stabilize the patient's injury and facilitates subsequent diagnosis and treatment. The operation is simple and convenient; adjusting the traction force by rotating the stud allows for precise adjustment. Furthermore, the device's compact structure makes it highly effective in emergency rescue. 2. This invention, by setting up a support assembly, allows the fixed columns in the support assemblies on both sides to be pulled out and separated from the inside of the rotating head. The angle of the support frame is adjusted so that the foot column replaces the bracket to support the device, thereby achieving the purpose of raising the patient's leg. After adjustment, the device is fixed at the adjusted height by inserting the fixed column into the inside of the rotating head. This achieves the purpose of raising the patient's leg to the optimal height, and the height of the elevation is highly flexible, thus meeting various needs during use. Attached Figure Description

[0018] 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.

[0019] Refer to the instruction manual appendix Figures 1-7 As shown in the figure, an emergency rescue fracture rapid fixation traction frame according to an embodiment of the present invention includes a support 1, a lower leg fixation member 2 fixedly connected to the inner side of the support 1, a lower leg Velcro 3 fixedly connected to the outer side of the lower leg fixation member 2, a connecting strap 4 fixedly connected to one side of the lower leg Velcro 3, a thigh fixation member 5 fixedly connected to one end of the connecting strap 4, a thigh Velcro 6 fixedly connected to the outer side of the thigh fixation member 5, and an arc-shaped crossbar 7 fixedly connected to the inner side of the support 1, the arc-shaped crossbar 7 being arranged with an arc-shaped contour.

[0020] Both the calf fixation piece 2 and the thigh fixation piece 5 are made of soft material and are used to cover and fix the patient's calf and thigh respectively. The calf fixation piece 2 and the thigh fixation piece 5 are fixed by the calf Velcro 3 and the thigh Velcro 6 respectively. The calf Velcro 3 and the thigh Velcro 6 make it more convenient and secure to fix the patient's legs.

[0021] One end of the bracket 1 is provided with a traction component, which includes an end support plate 8 fixedly connected to one end of the bracket 1. An adjusting stud 9 is threadedly connected inside the end support plate 8. A rotating handle 10 is fixedly connected to one end of the adjusting stud 9. A kit 11 is rotatably sleeved on the end of the adjusting stud 9 away from the rotating handle 10. A heavy weight indicator 12 is fixedly connected to one end of the kit 11. The heavy weight indicator 12 is an elastic structure. Two first adjusting bolts 13 are inserted inside the heavy weight indicator 12. The two first adjusting bolts 13 are arranged symmetrically on the axis. A first nut 14 is threadedly connected to the outer side of each of the two first adjusting bolts 13. A first connecting chain 15 is fixedly connected to the side of the heavy weight indicator 12 away from the kit 11.

[0022] A small-weight position indicator 16 is sleeved at one end of the first connecting chain 15. The small-weight position indicator 16 is an elastic structure, and its elasticity is less than that of the large-weight position indicator 12. Two second adjusting bolts 17 are inserted inside the small-weight position indicator 16. The two second adjusting bolts 17 are arranged symmetrically along an axis, and a second nut 18 is threaded onto the outer side of each of the two second adjusting bolts 17. A second connecting chain 19 is sleeved on the side of the small-weight position indicator 16 away from the first connecting chain 15. The connection method between the first connecting chain 15 and the second connecting chain 19 can improve the efficiency of use. For flexibility, a foot limiting plate 20 is provided on the inner side of the arc-shaped crossbar 7. A foot bracket 21 is fixedly connected to the bottom of the foot limiting plate 20. The foot limiting plate 20 and the foot bracket 21 are combined to form an L-shaped profile to adapt to the shape of the foot. The bottom profile of the foot bracket 21 is adapted to the inner profile of the arc-shaped crossbar 7. A foot Velcro 23 is fixedly connected to one side of the foot limiting plate 20. A foot fixing member 22 is fixedly connected to the inner side of the foot Velcro 23. A pulling strap 24 is fixedly connected to one side of the foot fixing member 22. A second connecting chain 19 is sleeved on one side of the pulling strap 24.

[0023] It should be noted that, when applying traction to fix the fractured leg, the lower leg Velcro 3 and thigh Velcro 6 are removed, the lower leg fixation piece 2 and thigh fixation piece 5 are unfolded, and the foot Velcro 23 is removed to remove the foot fixation piece 22. The patient's leg is placed inside the lower leg fixation piece 2 and thigh fixation piece 5, and the patient's foot is placed inside the foot limiting plate 20 and foot bracket 21, ensuring that the patient's foot is in close contact with the foot limiting plate 20 and foot bracket 21. The foot fixation piece 22 is then attached to the affected leg. The instep is secured by fastening the Velcro straps 23 at both ends. The patient's foot is then immobilized. Traction is applied to the patient's leg via the traction assembly. Rotating the handle 10 causes the adjusting screw 9 to slide away from the heavy-duty indicator 12, thereby pulling the foot fixation component 22 via the traction strap 24. This allows the foot fixation component 22 to traction the patient's leg by securing the foot. During this process, the patient's body must remain stationary. The first adjusting bolt 13 and the small-weight positioning element 16 will be pulled simultaneously. Since both the large-weight positioning element 12 and the small-weight positioning element 16 are elastic structures, and the elasticity of the small-weight positioning element 16 is less than that of the large-weight positioning element 12, the small-weight positioning element 16 will undergo tensile deformation after the patient's leg is pulled to a certain extent. Because the patient's leg has already been pulled before the small-weight positioning element 16 deforms, that is, the patient's leg has already been pulled when the small-weight positioning element 16 deforms. If at this time... When applying traction to small-sized patients, the traction can be stopped when the small-weight indicator 16 deforms. This also allows for a further assessment of the patient's approximate body size, enabling control over the degree of deformation of the small-weight indicator 16. Specifically, when applying traction to smaller-sized patients such as teenagers, traction can be stopped when the small-weight indicator 16 begins to deform. If the patient is larger, traction can be stopped when the small-weight indicator 16 deforms more significantly. This ensures that the traction force remains within a safe range, preventing excessive traction that could cause injury to the patient.

[0024] After the small-weight indicator 16 is stretched and deformed until both sides are in contact with the second adjusting bolt 17 and the second nut 18, the stretching of the small-weight indicator 16 is limited by the second adjusting bolt 17 and the second nut 18, so it cannot be stretched further. If the handle 10 is rotated at this time, the large-weight indicator 12 will gradually deform as the traction force on the patient increases further. If the patient is a large-sized patient, i.e., an adult or other heavier body type, the deformation of the large-weight indicator 12 can be stopped. At the same time, the degree of deformation of the large-weight indicator 12 can be further adjusted according to the actual body type of the patient. That is, when the patient is tall and fat, the large-weight indicator 12 can be stretched until it is limited by the first adjusting bolt 13 and the first nut 14 and then stopped. After the traction is completed, the lower leg fastener 3 and the thigh fastener 6 are fastened to fix the patient's leg with the lower leg fixator 2 and the thigh fixator 5.

[0025] This allows patients to be roughly divided into two categories based on their body size. The deformation of the small-weight indicator 16 and the large-weight indicator 12 is used to ensure that the traction force is within the allowable range. This facilitates the application of traction to fracture patients during emergency treatment, enabling initial treatment, stabilizing the patient's injury, and facilitating subsequent diagnosis and treatment. The operation is simple and convenient. Adjusting the traction force by rotating the stud 9 allows for precise adjustment. The device is also compact and can play a good role in emergency rescue.

[0026] It is important to note that the elasticity of the small-weight position indicator 16 and the large-weight position indicator 12 must be strictly within the allowable traction force range for the two body types of patients mentioned above, so as to ensure that the traction force required for the deformation of the small-weight position indicator 16 and the large-weight position indicator 12 is lower than the average traction force required for the two types of patients, thereby ensuring that no further damage is caused to the patient when emergency traction is applied.

[0027] Furthermore, one end of the bracket 1 is rotatably connected to a connecting sleeve 25, the inner side of the connecting sleeve 25 is threaded to a bracket 26, the inner side of the bracket 26 is fixedly connected to a reinforcing rod 27, and a support assembly is provided on the outer side of the bracket 1. The support assembly includes a rotating head 28 rotatably connected to one side of the bracket 1, a support frame 29 fixedly connected to the outer side of the rotating head 28, and a foot post 31 fixedly connected to one end of the support frame 29. The support frame 29 and the foot post 31 form a U-shaped profile. A shaft 30 is fixedly connected to one side of the bracket 1, the rotating head 28 is rotatably connected to the outer side of the shaft 30, and a fixed post 32 is slidably connected to the outer side of the shaft 30. The fixed post 32 has a polygonal profile and is slidably connected to the inner side of the rotating head 28. The inner profile of the rotating head 28 matches the outer profile of the fixed post 32. The support assembly is set in two sets, and the two sets of support assemblies are symmetrically distributed.

[0028] It should be noted that when transferring the patient to the bed, the hanging bracket 26 can be connected to the connecting screw sleeve 25. By hanging the hanging bracket 26 on the headboard, the device can be fixed, ensuring that the patient's legs will not shift. This ensures the stability of the patient's legs during transfer. When it is necessary to raise the patient's legs to the optimal height, after the patient is fixed and tractioned, the fixing column 32 in the two-sided support assembly can be pulled to disengage it from the inside of the rotating head 28. At this time, by rotating the rotating head 28, the angle of the support frame 29 can be adjusted, and the foot column 31 can replace the bracket 1 to support the device, thereby achieving the purpose of raising the patient's legs. After adjustment, the fixing column 32 can be inserted into the inside of the rotating head 28 to fix the rotating head 28, thus fixing the device at the adjusted height. This achieves the purpose of raising the patient's legs, and the height of the raising is highly flexible, which can meet various needs during use.
