Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a foldable ASO gangrene care support stent. Background Technology

[0002] Nursing support frames are designed primarily to meet the specific needs of medical care, rehabilitation therapy, and daily life, providing support, fixation, and protection for body parts to promote rehabilitation, reduce discomfort, improve self-care ability, and enhance safety. The core function of existing nursing support frames is lower limb rehabilitation training support (such as skeletal traction and postural fixation). They utilize a triangular / trapezoidal structure to elevate and adjust the angle of the affected limb, and are suitable for post-orthopedic immobilization or rehabilitation exercises.

[0003] Patent CN 215385443 U discloses a lower limb care and rehabilitation support. By setting a horizontal brace, a first hole, a second hole, and a locking post, the height and width of the support frame can be adjusted according to the patient's height and weight. By setting bolts, the support frame can be adjusted into a triangular structure, which is beneficial to lower limb blood circulation, reducing swelling and providing comfort. By setting pins, it is easy to fold, making the support frame easy to store and carry. By setting bolts, the support frame can be adjusted into a trapezoidal structure, so that the affected limb is in a bent position, which is convenient for bone traction.

[0004] Patients with ASO (Arteriosclerosis Obliterans) gangrene are those whose limbs suffer from persistent ischemia due to arteriosclerosis obliterans, eventually developing into dry or wet gangrene. Nursing care for ASO gangrene patients often requires simultaneously maintaining limb elevation and wound exposure, as well as frequent dressing changes. When using the aforementioned lower limb rehabilitation braces, due to their combination of horizontal, vertical, inclined, and fixed braces, adjustments to height, width, and angle are achieved through multiple components such as pins, bolts, threaded sleeves, and spring clips. The adjustment process is cumbersome (requiring multiple disassembly and reassembly of components), making it difficult to quickly switch functional states. Therefore, they are unsuitable for the positional adjustment needs of ASO gangrene patients during frequent dressing changes. Summary of the Invention

Detailed Implementation

[0061] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0062] Example 1

[0063] A foldable ASO gangrene care support bracket includes a rotating support structure 1, a cross brace 2, and a support pad 3.

[0064] Specifically, the foldable ASO gangrene care support bracket includes two parallel rotating support structures 1. Each rotating support structure 1 includes a rotating joint 11 and two angled support rods 12. The two angled support rods 12 are connected by the rotating joint 11, allowing for angle adjustment. A cross brace 2 and a support pad 3 are positioned between the two rotating support structures 1, serving to connect, support, and synchronize the parallel support rods 12 between the two rotating support structures 1.

[0065] In this embodiment, by adjusting the included angle between the support rods 12 of the rotating support structure 1, which are set at an angle, different usage conditions can be accommodated. When the included angle is greater than 60°, the side of each rotating support structure 1 away from the rotating joint 11 is in contact with the bed surface, forming a triangular structure between the two support rods 12 and the bed surface, which can be used to support the bed blanket. When the included angle is less than 60°, one of the support rods 12 of each rotating support structure 1 is in full contact with the bed surface, while the other support rod 12 is tilted upwards, which can be used to elevate the affected limb.

[0066] This embodiment features a simple, easily adjustable foldable ASO gangrene care support frame that integrates two functions.

[0067] Example 2

[0068] A foldable ASO gangrene care support stent, such as Figure 3 As shown, each support link 12 has a telescopic adjustment rod 13 at the end away from the rotating joint 11.

[0069] Specifically, in each rotating support structure 1, a plurality of holes 131 are spaced apart along the axial direction on the telescopic adjustment rod 13 corresponding to one of the support rods 12. The support rod 12 is provided with threaded holes 121. The support rod 12 and the telescopic adjustment rod 13 are detachably connected through the threaded holes 121, the fixing bolts 4 and the holes 131.

[0070] Specifically, such as Figure 4As shown, the fixing bolt 4 includes a handle, a threaded part 41, and a rod part 42 arranged in sequence. After adjusting the relative position between the telescopic adjustment rod 13 and the support connecting rod 12 as needed, rotating the handle causes the threaded part 41 to be threaded into the threaded hole 121 and the rod part 42 to gradually extend into the corresponding hole 131 to achieve axial limiting of the telescopic adjustment rod 13 and lock the relative position between the telescopic adjustment rod 13 and the support connecting rod 12.

[0071] In this embodiment, by adjusting the included angle between the support rods 12 of the rotating support structure 1, which are set at an angle, different usage conditions can be accommodated. When the included angle is greater than 60°, such as Figure 1 As shown, the telescopic adjustment rods 13 corresponding to the two support rods 12 of each rotating support structure 1 are in contact with the bed surface, forming a triangular structure between the rotating support structure 1 and the bed surface, which can be used to support the bed blanket. Figure 2 As shown, when the included angle is below 60°, one of the support rods 12 and its corresponding telescopic adjustment rod 13 of each rotating support structure 1 are in overall contact with the bed surface, while the other support rod 12 and its corresponding telescopic adjustment rod 13 are tilted upwards, which can be used to elevate the affected limb.

[0072] The rest is the same as in Example 1.

[0073] In this embodiment, a telescopic adjustment rod 13 is provided at the end of the support link 12, which can quickly achieve fine-tuning of the height.

[0074] Example 3

[0075] A foldable ASO gangrene care support bracket includes a rotating joint 11 comprising a bearing, a limiting groove, and a locking bolt. The two support rods 12 of each rotating support structure 1 are connected by the bearing and their angle is adjustable. A limiting groove is provided on the bearing, and the locking bolt passes through the limiting groove to lock the bearing, thus locking the angle. The rest is the same as in Embodiment 2.

[0076] Example 4

[0077] A foldable ASO gangrene care support bracket has a rotating joint 11 including a rotating connector 111. The two support rods 12 of each rotating support structure 1 are connected by the rotating connector 111 to achieve angle adjustment.

[0078] Specifically, such as Figures 5-6 As shown, one of the rotary support structures 1's rotary joints 11 also includes a gear set 112, and the rotary connector 111 includes a rod body and threaded structures and locking handles disposed at both ends of the rod body. Figure 7As shown, the gear set 112 includes two coaxial gears that are capable of meshing with each other, located on the opposing sides of the two support rods 12. Each gear is fixedly connected to its corresponding support rod 12. The rotating connector 111 of the rotating support structure 1 passes through the gears, with one end threadedly connected to the inner support rod 12 and the other end connected to the locking handle on the outer side of the outer support rod 12. When it is necessary to adjust the angle between the two support rods 12, the locking handle is rotated in the opposite direction, causing a portion of the threaded structure of the rotating connector 111 to disengage from the threaded hole of the inner support rod 12. The two gears separate and no longer mesh, allowing the angle between the two support rods 12 to be adjusted. After the angle is adjusted, the locking handle is rotated in the forward direction, causing the threaded structure of the rotating connector 111 to continue screwing into the threaded hole of the inner support rod 12. The two gears approach each other and mesh, thus locking the angle between the two support rods 12 through gear meshing.

[0079] The rest is the same as in Example 2.

[0080] Example 5

[0081] A foldable ASO gangrene care support bracket includes a rotating joint 11 of another rotating support structure 1, the rotating connector 111 of which includes a rod. One end of the rod is fixed to the inner support rod 12, and the other end passes through the outer support rod 12. Furthermore, an adjustment allowance is provided between the two support rods 12 of the rotating support structure 1 to prevent compression deformation during angle adjustment and locking of the rotating support structure 1 described in Embodiment 4.

[0082] Specifically, such as Figures 8-9 As shown, when the two gears separate, the outer support link 12 moves to the right as a whole, and the left outer support link 12 contacts the end of the inner support link 12. Figures 10-11 As shown, when the two gears mesh, the outer support link 12 moves to the left as a whole, and a gap is left between the ends of the outer support link 12 and the inner support link 12 as an adjustment margin.

[0083] The rest is the same as in Example 4.

[0084] Example 6

[0085] A foldable ASO gangrene care support bracket has a cross brace 2 and a support pad 3 between the inner support rods 12, and a cross brace 2 and a support pad 3 between the outer support rods 12. The cross brace 2 is provided between the inner support rods 12 near the rotating joint 11.

[0086] As a preferred technical solution, in this embodiment, such as Figure 12 As shown, the rotating joint 11 is marked with an angle scale.

[0087] The rest is the same as in Example 5.

[0088] Example 7

[0089] A foldable triangular ASO gangrene care support bracket employs a minimalist architecture of a rotating joint and a telescopic linkage. The rotating joint utilizes a composite structure of "damping bearing + limit slot + locking bolt" to achieve continuous angle adjustment, precise locking, and mechanical load-bearing capacity.

[0090] Two foldable telescopic rods are connected by a rotating joint. In the horizontal position, the joint angle is more than 60° (when the support cover is unfolded), and in the tilted position, it rotates to 30°-60° (forming a 30°-60° elevation angle) without disassembling any parts. The end of the rod is equipped with a telescopic adjustment rod (with built-in spring lock), which can complete the height fine adjustment within 10 seconds (15-25cm in the horizontal position, and a maximum of 30cm in the tilted position).

[0091] This embodiment adopts a dual-function integrated design, combining a support frame and a raised frame into one:

[0092] (1) Horizontal support state: The support is unfolded into an isosceles triangle, with the top horizontal bar 15-25cm away from the bed surface, forming a "support blanket space". The support blanket is away from the affected limb. The memory foam buffer layer (2-3cm thick) is used to support the blanket, avoiding direct pressure of the blanket on the ASO gangrene wound, reducing pain and infection risk.

[0093] (2) Tilt and Elevate Position: Rotate the joint to a tilt angle of 30°-60° and raise the affected limb by 30cm (in accordance with the 30°-45° elevation angle required by the ASO nursing guidelines) to promote venous return and provide nurses with operating space to bend over and change dressings.

[0094] This embodiment of the support frame represents a breakthrough from "general-purpose rehabilitation support" to "customized support for specialized nursing scenarios." It not only meets the need to "avoid compressing the wound with blankets" but also addresses the specific nursing scenario of ASO gangrene patients, who "need to maintain both limb elevation and wound exposure simultaneously." Furthermore, through structural design, this embodiment of the support frame achieves an innovation from "complex adjustment of multiple components" to "dynamic reconstruction of a single joint," resulting in a simple structure and convenient operation.

[0095] The support frame in this embodiment is less than 5cm thick when fully folded, allowing it to be placed flat under a standard medical bed (bed height is typically ≥10cm). The overall weight is less than 1.5kg (using aviation aluminum alloy connecting rods and engineering plastic joints), making it easy for nurses to carry with one hand. It is suitable for use in various scenarios, including bedside, dressing room, and during transport. From its folded state to its fully unfolded state, only three steps are required (unlock the telescopic rod → rotate the joint to the target angle → lock the height), improving efficiency by 70% compared to the existing technology's "removing bolts + adjusting the frame + re-fixing" process. It is particularly suitable for the rapid positioning support needs of ASO patients requiring frequent dressing changes.

[0096] Example 8

[0097] A foldable triangular ASO gangrene care support frame, based on Example 7, further incorporates a pressure-ulcer-preventing cushioning design. The support surface layer that contacts the affected limb has a built-in memory foam cushioning pad, which disperses pressure points and avoids the compression of bony prominences such as the fibular head, medial and lateral malleoli by traditional rigid supports, thus preventing pressure injuries. Specifically, the support surface that contacts the affected limb employs a three-layer structure:

[0098] (1) Bottom layer: aviation aluminum alloy frame (2mm thick), directly connected to the connecting rod, bearing the function of mechanical transmission, and the surface is machined with threaded holes for fixing the end of the connecting rod.

[0099] (2) Middle layer: memory foam cushioning pad (2-3cm thick), pasted on the top of the aluminum alloy frame, covering only the area in contact between the frame and the affected limb, and not extending to the connecting rod folding joint or telescopic part.

[0100] (3) Outer layer: antibacterial and breathable fabric, wrapped around the cushioning pad and sewn to the edge of the skeleton, with no direct connection to the connecting rod.

[0101] The support surface in this embodiment has easy-to-clean and disinfect characteristics. The finishing layer adopts seamless one-piece molding technology, which avoids the gaps in traditional splicing structures that trap dirt. With its smooth surface, it can be directly wiped with chlorine-containing disinfectant (500-1000mg / L) or 75% ethanol to quickly complete disinfection and meet infection control requirements.

[0102] As a preferred technical solution, this embodiment can be equipped with key auxiliary markings: 30°, 45°, and 60° scale lines are marked at the joint, and the recommended angle range (30°-45°) is indicated in green. The safe adjustment range is distinguished by color, reducing operational errors.

[0103] As a preferred technical solution, this embodiment can have elastic band fixing buckles pre-reserved on the surface for connecting the bed rails or the patient's limbs to form a three-point fixation system (such as the ends of two connecting rods + limb fixation points), similar to the tripod principle, to further enhance the anti-tipping ability, especially suitable for scenarios where the patient is restless or turning over.

[0104] As a preferred technical solution, this embodiment can set fluorescent marking lines at the edge of the decorative layer to facilitate quick positioning of the support edge during nighttime nursing operations and avoid accidental contact with the wound.

[0105] The rest is the same as in Example 7.

[0106] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
