Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a limb positioning brace that is convenient to wear. Background Technique

[0002] A good limb position is a position or posture in which the limb is placed to maintain its good function. It is a temporary position designed from the perspective of treatment and nursing. And the placement of good limb position is the most basic treatment for stroke patients in the early stage, which can play a good role in inhibiting the spasm pattern, preventing shoulder joint subluxation, and early inducing isolated movement. Therefore, it is very important to take the correct position. At present, the placement of good limb position on the bed is mainly supine position, semi-sitting position, lateral position, healthy side lying position and affected side lying position. If the placement of good limb position is reasonable in the early stage, many complications can be avoided.

[0003] The Chinese Patent Network published a device for placing good limb position for hemiplegic patients, with the publication number CN219184394U, including a leg fixing plate, a base foot plate, a movable swing plate, an expansion airbag, a massage hole and a telescopic top airbag. The base foot plate is fixedly installed at the lower part of the leg fixing plate. The movable swing plate is swingably arranged above the base foot plate. An expansion airbag is arranged between the movable swing plate and the base foot plate. A massage hole is penetrated through the surface of the movable swing plate. A telescopic top airbag is arranged inside the massage hole. The telescopic top airbag is communicated with the expansion airbag. The device for placing good limb position of the utility model can not only position the good limb position of hemiplegic patients, avoid the problem of foot drop and varus of patients, but also take into account comfort and assist foot joint activities, and avoid foot stiffness and discomfort caused by long-term fixation of patients' feet.

[0004] The above device can position the placement of good limb position of patients, but in the process of its use, due to its inability to adjust according to the size of the patient's feet, the practical use has great limitations. Therefore, a limb positioning brace that is convenient to wear is proposed. Content of the Utility Model

[0030] In this embodiment, by setting the adjustment mechanism 2, when bundling the feet and positioning the toes, it can better fit the actual foot size of the patient. By adjusting the limit of the foot fixing plate 21 by the limiting rod 212, the device can be applied to patients with different foot sizes, which is more practical. And during use, it can be worn by simply bundling with straps, which is very convenient.

[0031] Embodiment 2

[0032] AsFigures 1 - 5 As shown, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that the fixing mechanism 3 includes two fixing baffles 32 and a rotating wheel 38. Two second T-shaped grooves are respectively formed on the front surface of the support plate 31. Two groups of T-shaped sliders 34 are respectively and slidably arranged on the inner walls of the two second T-shaped grooves. The front surfaces of the two groups of T-shaped sliders 34 are respectively fixedly connected to the back surfaces of the two fixing baffles 32. Two double-axis threaded rods 35 are respectively rotatably arranged on the left and right end faces of the inner walls of the two second T-shaped grooves through two groups of bearing seats I. Two groups of threaded holes are respectively formed on the left side surfaces of the two groups of T-shaped sliders 34. The surfaces of the two double-axis threaded rods 35 are respectively threadedly connected to the inner wall surfaces of the two groups of threaded holes. A second square groove is formed in the support plate 31. A worm 37 is rotatably arranged on the bottom surface of the inner wall of the second square groove through a bearing seat II. Two worm wheels 36 are respectively fixedly sleeved on the surfaces of the two double-axis threaded rods 35. The worm 37 is respectively meshed with the two worm wheels 36. The upper end of the worm 37 penetrates through the top surface of the inner wall of the second square groove and extends above the support plate 31. The bottom surface of the rotating wheel 38 is fixedly connected to the top end of the worm 37. Two groups of leg straps 33 are respectively fixedly arranged on the front surfaces of the two fixing baffles. The front surface of the support plate 31 is respectively slidably connected to the back surfaces of the two fixing baffles 32.

[0033] In this embodiment, by providing the fixing mechanism 3, when the legs are tied, the device can better fit the patient's legs, and the fixing effect is better and not easy to loosen. Rotating the rotating wheel 38 can adjust the distance between the two fixing baffles 32, so that the device can be suitable for different patients when tying the legs.

[0034] During use, first place the patient's legs between the two fixing baffles 32, rotate the rotating wheel 38 to synchronously rotate the worm 37, thereby driving the two worm wheels 36 to rotate, and further causing the two double-axis threaded rods 35 to rotate. When the double-axis threaded rods 35 rotate, they will drive the two groups of T-shaped sliders 34 to move, and the distance between the two T-shaped sliders 34 can be adjusted, that is, the two fixing baffles 32 can be adjusted to make the two fixing baffles 32 fit the patient's legs more closely. Then use the leg straps 33 to further tie and fix the patient's legs. Fit the patient's feet to the foot fixing plate 21, and adjust the foot fixing plate 21 according to the size of the patient's feet. Lifting the lifting rod 27 will cause the connecting rod 211, the circular slider 210 and the limiting rod 212 to move upward. At this time, the spring 29 is in a compressed state, and the limiting rod 212 disengages from the limiting hole 28 and no longer limits the foot fixing plate. Pulling the pull rod 26 can make the foot fixing plate 21 slide on the bottom plate 1, so that the toe positioning sleeve 24 fixedly arranged on the foot fixing plate 21 moves to a position where it fits the patient's toes. Then release the lifting rod 27, and the spring 29 will bounce the limiting rod 212 back into the limiting hole 28, so that the limiting rod 212 limits and fixes the foot fixing plate 21. Then put the toe positioning sleeve 24 on the patient's toes, and tie and fix the patient's feet with the foot strap 23, so that the feet and toes are positioned to avoid curling.

[0035] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any simple changes, equivalent substitutions or modifications made on the basis of the present utility model to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present utility model.
