Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a limb suspension bracket. Background Technology

[0002] In orthopedic clinical treatment, limb suspension is a commonly used nursing procedure, primarily used for limb fixation and reduction assistance in patients with fractures and joint dislocations, as well as postoperative rehabilitation training. Its purpose is to reduce the weight-bearing load on the limb through proper suspension, maintain the limb's normal physiological position, promote fracture healing, and prevent complications such as joint stiffness and muscle atrophy due to disuse. Simultaneously, limb suspension devices can also assist in rehabilitation programs such as muscle strengthening exercises and joint range of motion training, providing support for the patient's postoperative functional recovery. Currently, the types of limb suspension devices commonly used in clinical practice are relatively limited, and most have the following shortcomings: First, the fixing methods are cumbersome and have poor adaptability, making it difficult to securely fix them to bed rails of different sizes, and they are prone to loosening after fixing, affecting the stability of the suspension; second, the adjustment flexibility is insufficient, and most can only achieve height adjustment in one direction, unable to make multi-dimensional adjustments according to the patient's limb position and suspension angle requirements, making it difficult to accurately adapt to the limb shape and treatment needs of different patients; third, there is a lack of effective safety protection structures during the suspension process, which can easily lead to chain detachment, limb slippage, component collision, etc., posing safety hazards.

[0003] With the continuous development of medical device technology, limb suspension devices are developing towards flexibility, safety, and multi-functionality. There is an urgent need for a limb suspension brace that is compact in structure, easy to adjust, highly adaptable, safe, and has auxiliary rehabilitation and cushioning protection functions, as well as clearly defined medical use boundaries, in order to solve the above-mentioned problems of existing technologies, improve the quality of clinical nursing and patient rehabilitation experience, and at the same time avoid the risks of unauthorized use.

Detailed Implementation

[0021] 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.

[0022] This invention discloses a limb suspension bracket, according to the attached... Figures 1-11 As shown, the device includes a positioning disc 1, a cantilever arm 2, and a hanging rod 3. The positioning disc 1 is used to clamp onto the bed rail, and a vertical rod 16 is inserted into the inner side of the positioning disc 1. An adjusting sleeve 22 is fitted onto the cantilever arm 2, allowing it to slide and be adjusted. The adjusting sleeve 22 is fitted onto the outer side of the vertical rod 16, allowing it to slide and be adjusted. The hanging rod 3 is fitted onto the outer side of the cantilever arm 2, allowing it to slide and be adjusted. The hanging rod 3 is arc-shaped, and multiple sets of adjusting collars 32 are evenly arranged on the inner arc side of the hanging rod 3 to facilitate suspension of the limbs from different angles. The positioning plate 1 provides basic fixation between the support and the bed railing, while the vertical rod 16 provides vertical support for the cantilever arm 2 and the hanging rod 3. The adjusting sleeve 22 slides bidirectionally on the vertical rod 16 and the cantilever arm 2, allowing the cantilever arm 2 to adjust its vertical height and horizontal position. The hanging rod 3 can slide on the cantilever arm 2 to adjust its lateral position. The multiple sets of adjusting collars 32 on the arc-shaped hanging rod 3 allow for selection of suspension points according to needs, enabling limb suspension at different angles. The sliding cooperation of each component constitutes the basic structure for the multi-dimensional adjustment of the support. The design of the arc-shaped hanging rod 3 and the multiple sets of adjusting collars 32 breaks the limitation of single-angle suspension, adapting to different limb shapes and different suspension treatment needs. The multi-component sliding adjustment method allows the support to flexibly adapt to different sizes of beds, improving the clinical adaptability of the equipment.

[0023] According to the appendix Figures 2-4As shown, the positioning disk 1 further includes a sleeve hole 11, which is fitted onto the outside of the vertical rod 16 and slidably connected to it. A clamping block 12 is fixedly connected to the front of the positioning disk 1. Two sets of clamping blocks 12 are provided. A sliding guide rod 121 is fixedly connected to the inner side of each clamping block 12. A bidirectional threaded rod 13 is inserted into the inner side of each clamping block 12. The top of the bidirectional threaded rod 13 passes through one of the upper clamping blocks 12 and is fixedly connected to a butterfly handle 131. The sleeve hole 11 provides a vertical sliding channel for the vertical rod 16, enabling initial height adjustment. Rotating the butterfly handle 131 drives the bidirectional threaded rod 13 to rotate. Because the clamping block 12 limits the threaded rod, its rotation causes the sliding component on its outer side to move along the sliding guide rod 121. The sliding guide rod 121 guides the movement of the component, preventing deviation, and ultimately achieving the clamping action on the bed rail. The sliding connection between the sleeve hole 11 and the vertical rod 16 provides a stable channel for adjusting the height of the vertical rod 16, ensuring the verticality of the vertical rod 16 during the adjustment process and improving the overall stability of the bracket.

[0024] According to the appendix Figures 2-4 As shown, further, a slider 14 is sleeved on the outside of the sliding guide rod 121. The slider 14 is provided with two sets of oppositely distributed sliders. A U-shaped groove 141 is opened on the front side of the slider 14. The openings of the U-shaped groove 141 are opposite to each other. The slider 14 is sleeved on the outside of the bidirectional threaded rod 13 and is threadedly connected to the bidirectional threaded rod 13. The bidirectional threaded rod 13 is used to drive the slider 14 to clamp the bed rail. A clamping bolt 15 is inserted into the rear side of the positioning plate 1. The clamping bolt 15 corresponds to the sleeve hole 11. The clamping bolt 15 passes through the positioning plate 1 to the inside of the sleeve hole 11 and abuts against the vertical rod 16. When the bidirectional threaded rod 13 rotates, it drives two sets of sliders 14 to move closer to or further away from each other along the sliding guide rod 12 through thread transmission. The opening of the U-shaped groove 141 can fit against the two sides of the bed rail, realizing the clamping and fixing of rails of different widths. After the vertical rod 16 is adjusted to the target height in the sleeve hole 11, the clamping bolt 15 is tightened. The end of the bolt abuts against the surface of the vertical rod 16, and the position of the vertical rod is locked by friction to prevent it from sliding.

[0025] According to the appendix Figure 5 As shown, the upper half of the vertical rod 16 is further provided with a rack 161. The rack 161 meshes with the toothed ring 2262 of the rotating part 226 on the subsequent adjusting sleeve 22. When the adjusting sleeve 22 slides vertically on the vertical rod 16, the toothed ring 2262 moves along the rack 161, forming a meshing transmission. At the same time, the toothed structure of the rack 161 can limit the toothed ring 2262, preventing the adjusting sleeve 22 from sliding freely on the vertical rod 16.

[0026] According to the appendix Figures 6-9As shown, the cantilever arm 2 is further configured as a racetrack shape. A fixing block 21 is sleeved on the outer side of the cantilever arm 2. The fixing block 21 is located in the middle of the cantilever arm 2 to strengthen the structural strength of the cantilever arm 2. An adjusting sleeve 22 is inserted into the outer side of the rear half of the cantilever arm 2. Sliding sleeves 221 are provided on both sides of the adjusting sleeve 22. The sliding sleeves 221 are sleeved on the outer side of the cantilever arm 2. A fixing bolt 222 is inserted into the outer side of the sliding sleeve 221. The fixing bolt 222 passes through the sliding sleeve 221 and abuts against the cantilever arm 2. A pin 223 is inserted into the inner side of the adjusting sleeve 22. A partition 224 is fixedly connected to the inner side of the adjusting sleeve 22. Compared to the straight rod structure, the racetrack-shaped cantilever arm 2 has stronger resistance to bending and deformation. The intermediate fixed sleeve block 21 further strengthens the structural strength of the middle part of the cantilever arm, preventing deformation of the cantilever arm 2 due to long-term suspension stress. The adjusting sleeve 22 is connected to the cantilever arm 2 through the sliding sleeves 221 on both sides. The sliding sleeves 221 can slide horizontally along the cantilever arm 2 to realize the horizontal position adjustment of the adjusting sleeve 22. Tightening the fixing bolts 222 can lock the relative position of the sliding sleeve 22 and the cantilever arm 2 through friction. The pin 223 provides fixed support for the subsequent rotating parts. The partition 224 divides the internal space of the adjusting sleeve 22, providing independent installation positions for each component and preventing mutual interference between components.

[0027] According to the appendix Figures 6-9 As shown, specifically disclosed, a first shaft 225 is inserted into the inner side of the adjusting sleeve 22, and a rotating member 226 is sleeved on the outer side of the first shaft 225. A through hole 2261 is opened at the bottom end of the rotating member 226, and the through hole 2261 is sleeved on the outer side of the pin 223. A toothed ring 2262 is provided on the outer side of the top end of the rotating member 226, and the toothed ring 2262 is meshed with the rack 161. A second shaft 227 is inserted into the inner side of the adjusting sleeve 22, and a spring clip 228 is sleeved on the outer side of the second shaft 227. The spring clip 228 is located between the partition plate 224 and the rotating member 226. The first shaft provides rotational support for the rotating component, which can rotate around the first shaft. A pin is sleeved in the through hole at its bottom end, and the pin limits the rotating component to prevent axial movement. When the adjusting sleeve slides on the vertical rod, the toothed ring 2262 at the top of the rotating component 226 meshes with the rack 161 of the vertical rod 16, providing a limiting effect. The spring clip 228 always provides elastic pressure to the rotating component 226, providing rotational force for the rotating component. When the adjusting sleeve 22 needs to be adjusted in height, the elastic force of the spring clip 228 can separate the toothed ring 2262 from the rack 161, making it convenient to adjust the height of the adjusting sleeve 22.

[0028] According to the appendix Figures 10-12As shown, specifically disclosed, a sliding sleeve 31 is fixedly connected to the middle part of the hanging rod 3 on the outer arc side. The sliding sleeve 31 is sleeved on the outer side of the front half of the lifting arm 2. A sliding sleeve hole 311 is opened on the inner side of the sliding sleeve 31, and the sliding sleeve hole 311 is slidably connected to the lifting arm 2. The sliding sleeve hole 311 is sleeved on the outer side of the lifting arm 2. A positioning bolt 312 is inserted into the outer side of the sliding sleeve 31, and the positioning bolt 312 passes through the sliding sleeve 31 to the inner side of the sliding sleeve hole 311 and abuts against the lifting arm 2. The sliding sleeve 31 forms a sliding fit with the lifting arm 2 through the sliding sleeve hole 311. The hanging rod 3 can slide horizontally along the lifting arm 2 with the sliding sleeve 31, realizing the adjustment of the lateral position of the hanging rod 3 to adapt to the lateral suspension needs of different patients' limbs. After adjusting to the target position, the positioning bolt 312 is tightened. The end of the bolt abuts against the surface of the lifting arm 2, and the relative position of the sliding sleeve 31 and the lifting arm 2 is locked by friction to prevent the hanging rod 3 from sliding.

[0029] According to the appendix Figures 10-12 As shown, a suspension chain 33 is fitted onto the adjusting collar 32, and a protective sleeve 34 is provided below the hanging rod 3. The protective sleeve 34 is used to attach the limb. A Velcro strap 35 is fixedly connected to the outside of the protective sleeve 34, and a hanging ring 351 is fixedly connected to the outside of the Velcro strap 35. The hanging ring 351 is fitted onto the other end of the suspension chain 33. According to the required limb suspension angle, one end of the suspension chain 33 is fitted onto the corresponding adjusting collar 32, and the other end is fitted onto the hanging ring 351 of the protective sleeve 34 to form a suspension connection. The patient's limb is placed in the protective sleeve 34, and the limb is quickly fixed inside the protective sleeve 34 by the fastening of the Velcro strap 35, preventing the limb from slipping out of the protective sleeve 34 during suspension. The protective sleeve 34 provides support and protection for the limb, and the suspension chain 33 transmits the suspension force to achieve limb suspension.

[0030] According to the appendix Figures 10-12 As shown, it is particularly important to emphasize that the suspension chain 33 adopts a stainless steel chain structure. The suspension chain 33 is equipped with a length adjustment buckle 331, which is used to adjust the overall length of the suspension chain 33. An anti-detachment buckle 332 is provided at the connection point between the suspension ring 351 and the suspension chain 33. The anti-detachment buckle 332 is used to prevent the suspension ring 351 from falling off the suspension chain 33, improving suspension safety. The stainless steel suspension chain 33 provides reliable tensile support for limb suspension. The length adjustment buckle 331 can change the effective suspension length of the suspension chain 33 through a buckle structure, realizing fine-tuning of the limb suspension height to adapt to the different limb suspension height needs of patients. The anti-detachment buckle 333 is an elastic buckle structure; when the suspension ring 351 is fitted and fastened to the anti-detachment buckle 333, the connection position between the suspension ring 351 and the suspension chain 33 is locked, preventing the suspension ring 351 from falling off the suspension chain 33.

[0031] According to the appendix Figures 10-12As shown, it is particularly important to emphasize that the inner side of the protective sleeve 34 is equipped with a breathable cotton padding layer. The surface of the breathable cotton padding layer has anti-slip textures. The breathable cotton padding layer is used to improve the comfort of limb suspension and prevent the limb from sliding inside the protective sleeve 34. The breathable cotton padding layer is in direct contact with the patient's limb. Its breathable material allows air circulation between the limb skin and the outside environment, reducing the accumulation of sweat. The anti-slip textures increase the friction between the cotton padding layer and the limb skin, preventing the limb from sliding inside the protective sleeve due to body movement or slight swaying of the support. At the same time, the cotton padding layer is made of flexible material, which can cushion the pressure of the protective sleeve on the limb and distribute local stress.

[0032] Working principle: In use, first align the two sets of sliders 14 of the positioning plate 1 with the bed railing, rotate the butterfly handle 131 to drive the bidirectional threaded rod 13 to rotate, causing the two sets of sliders 14 to slide relative to each other, so that the U-shaped groove 141 fits tightly against the bed railing, achieving a stable fixation of the positioning plate 1; then, according to the patient's limb suspension height requirements, adjust the height of the vertical rod 16 in the sleeve hole 11, and after adjustment, tighten the clamping bolt 15 to fix the vertical rod 16; next, adjust the horizontal position of the adjusting sleeve 22 on the cantilever arm 2 and the vertical position on the vertical rod 16. During the adjustment process, the toothed ring 2262 of the rotating part 226 moves along the rack 161 of the vertical rod 16, and the spring clip 228 limits the rotating part 226. Adjust to the appropriate position. After positioning, tighten the fixing bolt 222 to secure the adjusting sleeve 22. Then, adjust the position of the hanging rod 3 on the cantilever arm 2, tighten the positioning bolt 312 to secure the hanging rod 3, and according to the required suspension angle, attach the suspension chain 33 to the corresponding adjusting ring 32. Adjust the length of the suspension chain 33 using the length adjusting buckle 331. If the patient needs to perform joint range of motion training or muscle strength training, the auxiliary hanging rings 343 at both ends of the protective sleeve 34 can be attached to the appropriate adjusting rings 32 to achieve auxiliary fixation and cushioning protection of the limb. Finally, place the patient's limb inside the protective sleeve 34, secure the limb with the Velcro strap 35, ensure that the hanging ring 351 and the suspension chain 33 are firmly connected, and that the anti-slip buckle 332 is fastened to complete the limb suspension operation.
