Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical assistive device technology, and in particular to an improved boot for preventing foot drop. Background Technology
[0002] In cases of intertrochanteric fractures of the femur, femoral head and neck fractures, or fractures complicated by peroneal nerve injury, as well as after artificial hip joint or artificial femoral head replacement surgery, anti-rotation shoes are required to immobilize the affected limb to prevent complications such as foot drop, internal rotation, external rotation, and malunion.
[0003] The most commonly used anti-rotation shoes are T-shaped shoes. T-shaped shoes are made by nailing a wooden board to the outside of the flat heel of a regular low-cut shoe. The wooden board is perpendicular to the sole and forms a "T" shape. Because of the fixed structure and high hardness of the material, T-shaped shoes are prone to causing pressure sores on the patient's skin, causing discomfort. Moreover, the wooden board makes it very inconvenient for patients to turn over or get out of bed, which brings new problems such as pressure injury and deep vein thrombosis to the clinic. Utility Model Content

[0042] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0043] Reference Figure 1-5 The modified anti-foot drop boot shown includes:
[0044] The shaping board 100 is made of rigid material that matches the foot structure, making it resistant to deformation. It effectively supports the sole of the foot, maintains the foot's functional position, and prevents foot drop.
[0045] The perforated part 200 is opened on the shaping plate 100 and corresponds to the patient's heel area, providing necessary breathability and pressure relief, effectively avoiding the occurrence of instrument-induced pressure injury to the heel;
[0046] There are two outward expansion sections 300, located on both sides of the shaping plate 100 and corresponding to the bony prominences of the patient's foot. This provides more space for the bony prominences of the foot, effectively disperses pressure, prevents friction damage, and effectively avoids the occurrence of mechanical pressure injuries to the bony prominences of the foot.
[0047] The inner lining pad 400 is installed inside the shaping plate 100. The inner lining pad 400 improves comfort and reduces pressure on specific areas of the foot.
[0048] Multiple adjustable straps 500 are provided and mounted on the shaping plate 100. They are easy to adjust and can be used for different patients.
[0049] The soft pad 600 is set on the adjustable strap 500 to prevent the hard plastic plate from directly contacting the skin, further improving wearing comfort and reducing discomfort caused by prolonged use.
[0050] The working principle of this embodiment is as follows:
[0051] When wearing the modified boot, place it on the patient's foot, aligning the bony prominence of the foot with the outward expansion portion 300, and place the foot at the hollowed-out portion 200. Then, use the adjustable straps 500 to bind the modified boot, thus completing the wearing process.
[0052] Among them, the hollow part 200 provides the necessary breathability and pressure relief, effectively avoiding the occurrence of instrument-induced pressure injury to the heel, and the expanded part 300 effectively disperses pressure and prevents friction damage, effectively avoiding the occurrence of instrument-induced pressure injury to the bony prominence of the foot.
[0053] The 400-inch inner lining enhances comfort and reduces pressure on specific areas of the foot.
[0054] In some embodiments of this utility model, reference is made to Figure 3 As shown, the inner lining pad 400 has multiple irregularly arranged first ventilation holes 410, distributed in a staggered manner to ensure smooth air circulation. The inner surface of the inner lining pad 400 is sewn with breathable canvas 420. This canvas uses high-density weaving technology, has good breathability and softness, and can effectively wick away sweat to keep you dry and comfortable.
[0055] Among them, the first ventilation hole 410 helps to wick away sweat, keep feet dry, prevent bacterial growth, reduce odor, disperse material tension, increase the flexibility of the improved boot, and reduce the feeling of restriction. The design of the first ventilation hole 410 is more conducive to maintaining and regulating the temperature and humidity of the feet, wicking away moisture and preventing dampness, reducing overheating in cold environments and promoting heat dissipation in hot environments. It also has an anti-slip effect, increases friction, and effectively prevents the feet from sliding inside the boot. At the same time, the structural design of the first ventilation hole 410 can distribute pressure points, reduce pressure on specific areas of the feet, and improve comfort.
[0056] In some embodiments of this utility model, reference is made to Figure 1 As shown, the inner lining pad 400 is larger than the shaping plate 100, and its edge extends to the outer side of the shaping plate 100, so it can be fully covered, thus providing more comprehensive protection and effectively avoiding damage caused by possible collisions or friction between the foot and the outside world. It can better wrap the patient's foot, providing more comprehensive protection and a comfortable fit.
[0057] In some embodiments of this utility model, reference is made to Figure 2 As shown, the outer edge of the shaping plate 100 is wrapped with a first elastic rubber 110, which can buffer the impact of external forces on the shaping plate to a certain extent, and at the same time prevent the edge of the shaping plate from causing damage to the patient's leg or surrounding objects. The inner wall of the hollow part 200 is wrapped with a second elastic rubber 210, which effectively prevents the heel from rubbing against the inner wall of the hollow part and causing discomfort.
[0058] In some embodiments of this utility model, reference is made to Figure 1 As shown, the shaping plate 100 and the inner lining pad 400 adopt a semi-enclosed structure with the toes exposed at the ends, which is both comfortable and easy to observe the condition of the toes. It can effectively support and fix the patient's feet, prevent foot drop, and ensure the patient's flexibility during use, without hindering the patient from performing some simple leg activities.
[0059] In some embodiments of this utility model, reference is made to Figure 2 and Figure 4 As shown, the adjustable strap 500 includes:
[0060] Wearable component 510;
[0061] The suture section 520 is sewn onto the outside of the molding plate 100 to ensure a secure connection between the two and prevent them from easily coming apart.
[0062] The strap 530 is integrally formed with the suture site 520 and passes through the wearing part 510 and the padding 600 when worn, ensuring that the position of each part is stable during the user's wearing process, so as to play the best protective and auxiliary role. It is easy to adjust and can be used for different patients.
[0063] The Velcro 540 has two sections and is sewn onto the outside of the strap 530, which glues the two sections of the strap 530 together with the wearable part 510 as the center. The tightness of the strap can be easily adjusted by the Velcro to meet the needs of different patients.
[0064] When wearing the garment, the strap 530 is passed through the wearing part 510 and folded and then fastened together by two Velcro straps 540 to complete the wearing process.
[0065] In some embodiments of this utility model, reference is made to Figure 2 and Figure 4 As shown, the wearable component 510 includes:
[0066] The receiving part 511 is fixed to the outside of the plastic plate 100 by a buckle to ensure that it is stable and does not wobble;
[0067] The mouth-shaped frame 512 is rotatably mounted on the receiving part 511 and can be passed through by the strap 530 to achieve multi-angle adjustment.
[0068] To facilitate secure wearing, the strap 530 is designed to pass smoothly through the lip frame 512, allowing for easy adjustment of tightness according to individual needs.
[0069] In some embodiments of this utility model, reference is made to Figure 5 As shown, the center of the pad 600 has a channel 610 through which the strap 530 passes. The edges are finely polished to prevent wear and tear on the strap when it is inserted and removed. The position of the pad 600 can be adjusted as needed. The pad 600 has multiple irregularly arranged second ventilation holes 620. The ventilation holes 620 are of different sizes and are designed according to ergonomic and aerodynamic principles to greatly improve air circulation and provide a comfortable and dry environment for the user's feet.
[0070] The working method of this utility model:
[0071] When wearing the modified anti-foot drop boot, the patient first places their foot into the semi-enclosed space formed by the shaping plate (100) and the inner lining pad (400), ensuring that the heel is located in the hollow part (200) and the bony prominence of the foot corresponds to the outward expansion part (300). Then, the strap (530) is passed through the mouth-shaped frame (512) on the wearing part (510) and the channel (610) of the pad (600) in turn. According to their own comfort needs, the patient adjusts the tightness of the strap (530) through the Velcro (540) so that the modified boot fits tightly but does not cause excessive pressure on the foot.
[0072] During use, medical staff or patients should regularly check the breathable canvas (420) and padding (600) of the inner lining (400) for stains or damage, and clean or replace them promptly if necessary. At the same time, observe the patient's foot skin condition to ensure that the first elastic rubber (110) and the second elastic rubber (210) do not cause friction damage to the patient's skin. If the patient experiences discomfort or finds the modified boot's fixation effect unsatisfactory during use, the tightness of the straps (530) should be adjusted promptly, or the correct installation of each component should be checked.
[0073] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
