Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical rehabilitation devices, and particularly relates to a lower limb brace for knee support. Background Technique
[0002] Diabetic patients suffer from foot infections, ulcers, and / or deep tissue damage caused by distal nerve abnormalities and varying degrees of vascular lesions in the lower limbs. Treating diabetic foot infections requires careful wound management, good nutrition, the use of appropriate antibacterial drugs, good blood glucose control, and maintaining fluid and electrolyte balance.
[0003] When patients with mild or moderate infections cannot control their blood glucose well at home, cannot obtain or comply with proper wound care or decompression, have a need for antibacterial treatment but are not suitable for parenteral antibacterial treatment in the outpatient clinic, or need to undergo diagnostic tests or surgical consultations as soon as possible, hospitalization may be required.
[0004] Diabetic foot wound decompression is the key to wound care. There are already various devices available for reducing foot pressure, including plaster braces or other specialized footwear. The choice of device should be based on the wound location, the severity of the infection, and the presence or absence of peripheral arterial disease.
[0005] The fixing device of a lower limb brace without foot weight bearing described in the patent document with the publication number CN117481890A includes a calf support component and a knee joint support component. The calf support component is adapted to be detachably wrapped around the calf surface, the knee joint support component is fixedly connected to one end of the calf support component close to the knee joint, the knee joint support component is adapted to be detachably wrapped around the knee joint surface, and the inner side of the knee joint support component has an arc-shaped lifting surface for supporting the lower part of the knee joint.
[0006] The inner side surface of the knee joint support component is in an arc shape adapted to the knee joint, so as to wrap and fix the knee joint. The arc-shaped lifting surface therein is used to lift and support the lower part of the knee joint upward. The bony structures around the knee joint are supported through the knee joint support component. Among them, the arc-shaped lifting surface corresponding to the lower part of the knee joint is in a flared shape to achieve matching support with the lower part of the knee joint, which can well prevent the slipping and displacement of the brace, and further ensure the realization of the foot's non-weight-bearing function;
[0007] At the same time, the support device includes a connecting part and a foot support part. The connecting part is fixedly connected to the calf support component. One end of the foot support part forms a plane adapted to support the ground, and the other end is connected to the connecting part through an adjusting member. The adjusting member is used to adjust the connection position of the foot support part and the connecting part to adjust the overall length of the support device. When the patient stands or walks, etc., the foot support part can be used to support the ground.
[0008] However, through research, it is found that the above-mentioned lower limb brace has certain drawbacks during use:
[0009] Existing lower limb braces without foot weight-bearing fix the brace through the knee support component cooperating with the calf support component, so that the support device connected to the calf support component supports on the ground for the patient to stand or walk. However, the support device mainly forms a support at the heel part of the patient. When the patient walks, due to the small contact area, the standing stability is low and the walking support effect is poor, there are certain safety hazards. Utility Model Content

[0031] Embodiment 1:
[0032] A lower limb brace for knee support, as Figure 1 - Figure 2 shown, includes a brace main body 1, a shoe upper 6 arranged at the bottom of the brace main body 1, and a support structure arranged between the bottom of the brace main body 1 and the top of the shoe upper 6. The brace main body 1 includes a fixing sleeve 102, and a lifting sleeve 101 is integrally formed at the top of the fixing sleeve 102;
[0033] Among them, the lifting sleeve 101 is made of silica gel material. When the brace main body 1 is sleeved on the patient's calf, the lifting sleeve 101 can support at the bottom of the patient's knee joint (in this state, the inner surface of the lifting sleeve 101 also fits around the knee joint, and the bony structures around the knee joint are used for weight-bearing when the patient stands and walks with the aid of this lower limb brace), so as to avoid skin abrasion and ulceration around the knee joint due to the soft characteristics of the silica gel material lifting sleeve 101, thereby protecting the patient's skin;
[0034] Secondly, in order to fix the brace main body 1 on the patient's calf, as Figure 1 shown, multiple straps 2 are processed on one side of the lifting sleeve 101. By making the multiple straps 2 located on the side of the opening of the shoe upper 6, when the fixing sleeve 102 on the brace main body 1 is tied to the patient's calf through the multiple straps 2, the brace main body 1 can be fixed on the patient's calf (referring to the prior art here), so that the lifting sleeve 101 on the brace main body 1 supports at the bottom of the patient's knee joint.
[0035] A lower limb brace for knee support of the present utility model makes the lifting sleeve 101 on the brace main body 1 made of silica gel material. When the brace main body 1 is sleeved on the patient's calf and the fixing sleeve 102 is fixed on the calf, the lifting sleeve 101 can support at the knee joint when the patient stands or walks, and weight-bearing is carried out by means of the bony structures around the knee joint, avoiding skin ulceration due to abrasion around the knee joint.
[0036] Embodiment 2:
[0037] On the basis of Embodiment 1, as Figure 1 , Figure 3 and Figure 4 shown, this embodiment is the specific structure of the shoe upper 6 of the lower limb brace. The sole 9 is integrally formed at the bottom of the shoe upper 6;
[0038] Among them, the bottom surface of the sole 9 is arc-shaped. When the patient is walking, the situation of the bottom of the shoe upper 6 and the sole 9 contacting the ground is as Figure 4 shown, which is beneficial for the affected limb to walk close to the normal walking gait when walking;
[0039] Secondly, when the patient wears this lower limb brace, the diseased foot of the patient extends into the inner side of the shoe upper 6 from the inner side of the support structure, and the sole is kept in a state of hanging above the inner wall of the bottom of the shoe upper 6, which can avoid the direct pressure on the diseased foot of the patient due to its own gravity;
[0040] Furthermore, in order to increase the friction between the arc surface of the sole 9 and the ground when the patient wears the lower limb brace, anti-slip patterns are processed on the bottom surface of the sole 9, which can limit the slippage of the shoe upper 6 when it replaces the sole to support on the ground, thereby improving safety.
[0041] A lower limb brace with knee support of the present utility model ensures that there is always a contact area between the sole 9 and the ground when the affected limb is walking by setting a sole 9 with an arc surface at the bottom of the shoe upper 6. When the patient wears the brace main body 1 and extends his diseased foot into the inner side of the shoe upper 6 and is in a suspended state, the arc surface of the sole 9 contacts the ground, avoiding the affected limb from bearing weight when walking and making the affected limb walk close to the normal walking gait.
[0042] Embodiment 3:
[0043] Based on Embodiment 1 and Embodiment 2, as Figure 1 、 Figure 3 and Figure 4 shown, this embodiment is the support structure of the lower limb brace. The support structure includes two adjusting vertical plates 3. A plurality of adjusting notches 5 are processed inside one ends of the two adjusting vertical plates 3. Threaded rods 8 and round rods 7 are processed on the outer walls of both sides of one end of the shoe upper 6;
[0044] Among them, by arranging the threaded rod 8 and the round rod 7 vertically and symmetrically arranging the two adjusting vertical plates 3 on both sides of the brace main body 1 and the shoe upper 6, when the round rod 7 and the threaded rod 8 are inserted into two adjacent adjusting notches 5 on the adjusting vertical plate 3, one end of the adjusting vertical plate 3 can be sleeved outside the round rod 7 and the threaded rod 8, and the other ends of the two adjusting vertical plates 3 are fixedly processed with the brace main body 1. The distance between one end of the brace main body 1 and the shoe upper 6 can be adjusted by adjusting the connection of the round rod 7 and the threaded rod 8 in two adjusting notches 5 at different heights, so as to adapt to the legs of different patients;
[0045] At the same time, in order to facilitate the fixation of the shoe upper 6 that has completed the distance adjustment work with the brace main body 1, as Figure 1 and Figure 3As shown, one end of the threaded rod 8 is threadedly connected with a limit nut 4. By adjusting the threaded connection between the limit nut 4 and the threaded rod 8, the limit nut 4 presses the adjusting vertical plate 3 against the outer wall of the shoe upper 6, and the shoe upper 6 can be fixed to the support structure.
[0046] In the lower limb brace with knee support of the present utility model, by adjusting the threaded connection between the limit nut 4 and the threaded rod 8, the limit nut 4 presses the adjusting vertical plate 3 against the outer wall of the shoe upper 6. After the adjusting vertical plate 3 is connected to the round rod 7 and the threaded rod 8 through two adjusting notches 5 at different positions, the distance between the shoe upper 6 and the brace main body 1 can be adjusted, so as to facilitate adapting to the different lengths of the affected limbs of different patients, thereby ensuring that the foot of the affected limb is always suspended inside the shoe upper 6.
[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
