Description

Technical Field

[0001] The invention relates to the technical field of orthopedic medical appliances, in particular to an orthopedic nursing traction support device. Background Art

[0002] Traction is based on the principle of action and reaction in mechanics. It acts on the affected limb through the traction of gravity, relieves the tension and retraction of soft tissues at the fracture and dislocation, and repositions the fracture or dislocation to achieve the purpose of treatment. Traction is divided into two categories: continuous skin traction and bone traction. It is mainly used for cervical fractures, pelvic fractures, femoral neck fractures, intertrochanteric fractures, femoral shaft fractures, and unstable tibia and fibula fractures.

[0003] Due to the different angles and positions of the patient's leg pulling, the position and angle that need to be supported must also be adjusted accordingly. At present, when adjusting the orthopedic nursing traction support device, elastic clamping and bolt connection are mostly used for disassembly and adjustment. This method not only makes the adjustment inconvenient, but also when supporting the leg, the shaking force of the leg when shaking can easily lead to limited limiting strength. During elastic clamping, if the shaking force is large enough, the elastic buckle can easily be disengaged from the slot. During bolt connection, the shaking force impacts the thread of the bolt, which can easily cause the thread to be misaligned and stuck, affecting subsequent disassembly. In view of this, we propose an orthopedic nursing traction support device. Summary of the invention

[0010] As a further improvement of the technical solution, a sliding rod is fixedly connected to the bottom of one of the fixing rings, and the sliding rod passes through the supporting rod. The sliding rod is fixedly connected to a support plate on one side of the supporting rod cavity, and a mounting plate is slidably connected in the support plate. A connecting rod is fixedly connected to the side of the mounting plate away from the supporting plate, and the connecting rod is arranged directly above the inclined block.

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 9 As shown, the present embodiment provides an orthopedic nursing traction support device, including a bed body 100. An angle adjustment mechanism 200 is provided at the back plate of the bed body 100, which is used to adjust the angle of support for the patient's legs, so that medical staff can view the area blocked by the angle adjustment mechanism 200. A spacing adjustment mechanism 300 is provided on the angle adjustment mechanism 200, which is used to adjust the spacing between the two support components. According to the swelling of the patient's legs, the support points of the two support components are adjusted to improve the patient's comfort. A locking mechanism 400 is provided in the angle adjustment mechanism 200. When the patient places his legs on the support components of the spacing adjustment mechanism 300, the locking mechanism 400 is driven to fix the angle adjustment mechanism 200, so as to ensure that when the spacing adjustment mechanism 300 supports the patient, the angle adjustment mechanism 200 can remain stable, thereby providing stable and reliable support for the patient.

[0022] The existing orthopedic nursing traction support device requires the position and angle of support to be adjusted accordingly due to the different angles and positions of the patient's leg pulling. At present, the orthopedic nursing traction support device is mostly disassembled and adjusted by elastic clamping and bolt connection. This method not only causes inconvenience in operation during adjustment, but also the shaking force of the leg when supporting the leg is easy to lead to limited limiting strength. During elastic clamping, if the shaking force is large enough, it is easy to cause the elastic buckle to disengage from the slot. During bolt connection, the shaking force impacts the thread of the bolt, which is easy to cause the thread to be misaligned and stuck, affecting subsequent disassembly. Therefore, an angle adjustment mechanism 200 and a locking mechanism 400 are set. When the locking mechanism 400 is not subjected to force, there is a gap between the locking mechanism 400 and the inner wall of the angle adjustment mechanism 200, so that during the rotation of the angle adjustment mechanism 200, there is no excessive friction between the locking mechanism 400 and the angle adjustment mechanism 200, which not only avoids the wear of the locking mechanism 400, but also makes it easier to rotate the angle adjustment mechanism 200. When the patient supports the leg, the locking mechanism 400 is squeezed under the weight of the patient's leg, so that the locking mechanism 400 is forced to engage with the angle adjustment mechanism 200, thereby preventing the angle adjustment mechanism 200 from shaking or shifting when the device supports the patient, thereby providing a stable and reliable support for the patient. In addition, in the early stage of fracture, the patient's legs often swell significantly, but the support frame cannot adjust the support position according to the swelling of the patient's legs, which easily causes the legs to be over-compressed, thereby affecting blood circulation and being detrimental to swelling and recovery; therefore, a spacing adjustment mechanism 300 is provided, and the spacing adjustment mechanism 300 is manually adjusted to adjust the spacing value between the two support components in the spacing adjustment mechanism 300. When the leg swelling is more serious in the early stage of fracture, the spacing between the two support components can be appropriately widened to prevent the blood circulation from being affected by over-compression, thereby facilitating swelling reduction; and in the later stage of recovery, after the swelling subsides, the spacing between the two support components can be narrowed to enhance the fixation effect, thereby improving the patient's comfort during traction, and when checking the wound, adjusting the support points of the two support components is also convenient for medical staff to observe the swelling of the legs at the support location; Furthermore, a plurality of limiting holes are provided on the angle adjustment mechanism 200. After the supporting position of the angle adjustment mechanism 200 is flexibly adjusted according to the length of the patient's legs, the locking mechanism 400 can be engaged with adjacent limiting holes on the angle adjustment mechanism 200 to provide a stable fixing effect, thereby flexibly adapting to the treatment needs at different stages.

[0023] In order to facilitate medical staff to observe the patient's support, such as Figure 3 As shown, the specific structure of the angle adjustment mechanism 200 is further disclosed. The angle adjustment mechanism 200 at least includes a hollow column 210 slidably connected to the back plate of the bed body 100. A plurality of limit holes are arrayed on the hollow column 210. A movable rod 220 is slidably connected inside the hollow column 210. A fixed plate 221 is fixedly connected to the side of the movable rod 220 away from the hollow column 210. When medical staff need to observe the patient's leg condition, the movable rod 220 is manually rotated to drive the movable rod 220 to rotate inside the hollow column 210. The rotation of the hollow column 210 drives the fixed plate 221 to rotate, which is convenient for medical staff to check the original obstruction of the fixed plate 221 without disassembling the device, thereby improving the convenience of the device.

[0024] At different stages of fracture, the patient's leg swelling varies. In order to avoid excessive pressure on the patient, such as Figure 3As shown, the specific structure of the spacing adjustment mechanism 300 is further disclosed. The spacing adjustment mechanism 300 includes a support rod 310 slidably connected to both sides of the fixing plate 221. A No. 1 return spring 320 is fixedly connected to the two support rods 310. A fixing ring 321 is fixedly connected to the side of the No. 1 return spring 320 away from the support rod 310. The No. 1 return spring 320 is provided to drive the fixing ring 321 to better fit the patient's leg. The support rod 310 moves in the fixing plate 221 and cooperates with the No. 1 return spring 320 to drive the fixing ring 321 to move, so that the spacing value between the two fixing rings 321 can be adjusted. When the leg swelling is severe in the early stage of fracture, the spacing between the two fixing rings 321 can be appropriately widened to avoid excessive compression; and after the swelling subsides in the later stage of rehabilitation, the spacing between the two fixing rings 321 can be narrowed to enhance the fixing effect, thereby improving the patient's comfort during traction.

[0025] Considering that after the angle of the movable rod 220 is adjusted, it needs to be fixed, such as Figure 3-Figure 6 as well as Figure 8-Figure 9 As shown, the specific structure of the locking mechanism 400 is further disclosed. The locking mechanism 400 at least includes a limiting rod 410 slidably connected to the two circular holes of the movable rod 220. When unlocked, there is a distance between the limiting rod 410 and the inner wall of the hollow column 210. During the rotation of the movable rod 220, no excessive friction is generated between the limiting rod 410 and the hollow column 210, which not only avoids the wear of the limiting rod 410, but also makes it easier to rotate the movable rod 220. Before locking, the circular hole opened on the movable rod 220 and the adjacent limiting hole on the hollow column 210 must be aligned. By squeezing the limiting rod 410, the limiting rod 410 is driven to pass through the circular hole opened on the movable rod 220, and is engaged with the adjacent limiting hole on the hollow column 210. After the limiting rod 410 is engaged with the limiting hole on the hollow column 210, the portion of the limiting rod 410 extending to the outside of the hollow column 210 has a longer The length of the movable rod 220 makes the movable rod 220 and the hollow column 210 shake relative to each other. At this time, since the length from the limit rod 410 to the outside of the hollow column 210 is long enough, even if the hollow column 210 shakes, the hollow column 210 will not fall off the limit rod 410, thereby ensuring the reliability of the limit rod 410 after limiting the hollow column 210, and fixing the hollow column 210 and the movable rod 220 to avoid shaking or displacement between the hollow column 210 and the movable rod 220 when the device supports the patient, thereby providing stable and reliable support for the patient. The outer walls of the two limit rods 410 are fixedly connected with a No. 2 return spring 411, and the other side of the No. 2 return spring 411 is fixedly connected to the inner wall of the movable rod 220. A No. 2 return spring 411 is set, and when the limit rod 410 is not squeezed, the limit rod 410 can be driven to reset and move under the force of restoring the deformation of the limit rod 410.

[0026] In order to squeeze the limiting rod 410, thereby driving the limiting rod 410 to move, as shown in FIG. Figure 3-Figure 5 As shown, the inner wall of the movable rod 220 is slidably connected with a support rod 420, and the side of the support rod 420 close to the limit rod 410 is fixedly connected to a limit block 421, and the side of the support rod 420 away from the limit block 421 is fixedly connected to an inclined block 423. When the support rod 420 moves, the limit block 421 is driven to move, so that the limit block 421 squeezes the limit rod 410, driving the limit rod 410 to move.

[0027] Considering the need to drive the support rod 420 to move, Figure 3 and Figure 7 as well as Figure 8-Figure 9 As shown, a sliding rod 430 is fixedly connected to the bottom of one of the fixing rings 321, and the sliding rod 430 is arranged to penetrate the support rod 310, and a support plate 431 is fixedly connected to one side of the sliding rod 430 located in the cavity of the support rod 310, and a mounting plate 432 is slidably connected in the support plate 431, and a connecting rod 433 is fixedly connected to the side of the mounting plate 432 away from the support plate 431, and the connecting rod 433 is arranged directly above the inclined block 423, and the fixing ring 321 is in contact with the patient's leg, and the weight of the patient's leg squeezes the fixing ring 321, driving the sliding rod 430 to move, thereby driving the support plate 431 to slide inside the support rod 310, and then driving the mounting plate 432 to move, and the movement of the mounting plate 432 drives the connecting rod 433 to move, and the connecting rod 433 moves downward to squeeze the support rod 420, driving the support rod 420 to move.

[0028] It is necessary to ensure the stability of the support rod 420 when it moves, such as Figure 3 As shown, the inner wall of the movable rod 220 is fixedly connected to the limit ring 222, and the support rod 420 is slidably connected to the limit ring 222. The limit ring 222 is set. When the support rod 420 slides, the limit ring 222 can provide guidance and stability to the support rod 420, so that the movement of the support rod 420 is more stable. The side of the limit block 421 close to the limit ring 222 is fixedly connected with a No. 3 return spring 422, and the other side of the No. 3 return spring 422 is fixedly connected to the limit ring 222. When the inclined block 423 is not squeezed, the force of the No. 3 return spring 422 to restore the deformation can drive the support rod 420 and the inclined block 423 to reset and move, so as to prepare for the next clamping.

[0029] In order to drive the two support rods 310 to move synchronously, Figure 3 and Figure 7As shown, the outer wall of the movable rod 220 is slidably connected to a movable ring 230, and two rotating rods 231 are rotatably connected to the movable ring 230, and the two rotating rods 231 are rotatably connected to the bottom of the adjacent support rod 310 on the side away from the movable ring 230. The movement of the movable ring 230 is manually controlled to make the movable ring 230 slide on the outer wall of the movable rod 220, driving the rotating rod 231 to move. Under the length limit of the rotating rod 231, when the rotating rod 231 moves, the support rod 310 can be pulled to move.

[0030] Considering the need to ensure the stability of the moving ring 230 after adjustment, Figure 7 As shown, a plurality of positioning holes are provided on the outer wall of the movable rod 220, and the movable ring 230 is fixed to the hollow column 210 by bolts to ensure the stability of the movable ring 230 after adjustment.

[0031] Considering that the distance between the fixing ring 321 and the patient's legs needs to be adjusted in different traction heights, such as Figure 3 As shown, a positioning block 110 is fixedly connected to the back plate of the bed body 100, and the hollow column 210 is slidably connected to the positioning block 110. A plurality of through holes are provided on the positioning block 110. The hollow column 210 is fixed to the positioning block 110 by screws. By removing the screws, the hollow column 210 is manually moved to drive the hollow column 210 to slide inside the positioning block 110, thereby driving the movable rod 220, the support rod 310 and the fixing ring 321 to move. When moved to the appropriate position, the hollow column 210 is fixed by installing the screws.

[0032] Working principle: when the patient's legs need to be pulled, the patient's legs are first passed through the two fixing rings 321 in sequence, and then the patient is pulled. Then, the distance between the movable rod 220 and the patient can be adjusted according to the patient's height and body shape. The movable rod 220 is manually pulled to drive the movable rod 220 to slide inside the hollow column 210, thereby driving the fixing plate 221 to move, and then driving the support rod 310 to move. The movement of the support rod 310 drives the fixing ring 321 to move, so as to adjust the fixing ring 321 to a suitable supporting position according to the different body shapes and heights of the patients. Moreover, when the medical staff needs to observe the patient's leg condition, the movable rod 220 is manually rotated to drive the fixing plate 221 and the support rod 310 to rotate, thereby driving the fixing ring 321 to rotate, so that the medical staff can check the patient's legs, thereby improving the convenience of the device. And by manually removing the bolts, and then manually sliding the moving ring 230, the moving ring 230 is driven to slide on the outer wall of the movable rod 220, thereby driving the rotating rod 231 to move. Under the length limit of the rotating rod 231, when the rotating rod 231 moves, the support rod 310 can be pulled to move, so that the spacing value between the two fixing rings 321 can be adjusted. When the leg swelling is severe in the early stage of fracture, the spacing between the two fixing rings 321 can be appropriately widened to avoid excessive compression; and after the swelling subsides in the later stage of rehabilitation, the spacing between the two fixing rings 321 can be narrowed to enhance the fixing effect, thereby improving the comfort of the patient during traction; After adjusting the distance between the two fixing rings 321, the height of the hollow column 210 inside the positioning block 110 is manually adjusted so that the fixing ring 321 abuts against the patient's leg. The weight of the patient's leg squeezes the fixing ring 321, thereby driving the sliding rod 430 to move, and then driving the support plate 431 to slide inside the support rod 310. The movement of the support plate 431 drives the installation plate 432 to move, thereby driving the connecting rod 433 to move. The connecting rod 433 moves downward to squeeze the support rod 420, driving The support rod 420 slides, thereby driving the limit block 421 to move, so that the limit block 421 squeezes the limit rod 410, driving the limit rod 410 to move, so that the limit rod 410 passes through the round hole of the movable rod 220, and is engaged with the adjacent limit hole on the hollow column 210, thereby fixing the hollow column 210 and the movable rod 220, avoiding shaking or displacement between the hollow column 210 and the movable rod 220 when supporting the patient, and providing stable and reliable support for the patient.
