Description

Technical Field

[0001] This utility model relates to the technical field of diabetic foot protection devices, specifically to an adjustable angle diabetic foot protection device. Background Technology

[0002] Diabetic foot is a common and serious complication of diabetes. Patients are prone to foot ulcers, infections, and other symptoms, requiring special protection for their feet.

[0003] Existing diabetic foot protectors are usually a fixed, one-piece structure, which cannot meet the needs of patients for ankle movement and fixation in different situations.

[0004] For example, when diabetic foot is mild (mild ulcers), appropriate ankle movement can be beneficial. Slow flexion, extension, and rotation movements can promote blood circulation in the ankle, help maintain joint flexibility and muscle strength, and help prevent muscle atrophy and joint stiffness. They can also help reduce local edema and, to some extent, alleviate the further deterioration of diabetic foot ulcers.

[0005] When diabetic foot is severe (severe ulcers, infection, or significant foot pain, swelling, gangrene, etc.), excessive ankle movement may aggravate local damage, affect wound healing, or even lead to the spread of infection. In this case, it is necessary to limit ankle movement, focusing on rest and immobilization, and avoid weight-bearing and excessive activity to prevent further damage to the foot.

[0006] Existing protective sleeves are insufficient to meet both needs, restricting patients' activities and hindering the treatment and rehabilitation of diabetic foot. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable angle diabetic foot protection device that can switch between two states of ankle fixation and unfixation, thereby solving the technical problems existing in the prior art.

[0008] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: An adjustable-angle diabetic foot protection device includes: a foot support plate, with upright plates arranged around the foot support plate to form a foot groove for fixing the foot, and a foot strap provided on the upright plates; a leg support, one end of which is rotatably connected to the foot support plate, the leg support and the foot support plate forming an integral structure for fixing the lower leg and foot, and the leg support is provided with a leg strap; the connection between the foot support plate and the leg support corresponds to the ankle, and the rotation direction of the foot support plate relative to the leg support is consistent with the direction of flexion and extension movement of the ankle; and a limiting device, disposed at the connection between the foot support plate and the leg support, for limiting the rotation between the foot support plate and the leg support, and capable of manually releasing the applied restriction.

[0009] Furthermore, the foot support plate is symmetrically provided with two sets of first connecting members at the position where it connects to the leg bracket, and the leg bracket is symmetrically provided with two sets of second connecting members at the position where it connects to the foot support plate. The two sets of first connecting members are respectively connected to the two sets of second connecting members via a rotating shaft. The second connecting members are located outside the first connecting members, and the limiting device is provided on the second connecting members.

[0010] Furthermore, the first connector has a plurality of first limiting holes evenly spaced around the rotating shaft, and the second connector has at least one second limiting hole. The distance between the first limiting hole and the rotating shaft is the same as the distance between the second limiting hole and the rotating shaft, so that the first limiting hole and the second limiting hole are connected during the relative rotation of the foot support plate relative to the leg bracket. The limiting device includes a limiting plate, and the end of the rotating shaft near the second connector extends outward to form a limiting shaft. The limiting plate has a through hole at its center, through which the limiting shaft passes, and the limiting plate can move along the limiting shaft. The limiting plate has a limiting post perpendicularly arranged on its side facing the second connector. The limiting post can pass through the second limiting hole and the first limiting hole in sequence during the movement of the limiting plate toward the second connector.

[0011] Furthermore, a spring is sleeved between the limiting shaft and the limiting plate and the second connecting member. The spring is used to apply an elastic force away from the second connecting member to the limiting plate when the limiting device releases the applied restriction, so that the limiting post is at least disengaged from the first limiting hole.

[0012] Furthermore, the end of the limiting shaft is a threaded part, and a force-applying component is threadedly connected to the threaded part. By rotating the force-applying component, an external force that counteracts the elastic force is applied as the limiting plate moves toward the second connecting member, and this external force is removed as the limiting plate moves away from the second connecting member.

[0013] Furthermore, one end of the instep strap is fixedly connected to the foot support plate, and the other end of the instep strap is detachably connected to the foot support plate.

[0014] Furthermore, one end of the leg strap is fixedly connected to the leg support, and the other end of the instep strap is detachably connected to the leg support.

[0015] Furthermore, the inner sides of the instep strap and the leg strap are covered with a soft, breathable, and elastic material.

[0016] Compared with the prior art, this utility model has the following advantages: The adjustable-angle diabetic foot protection device provided by this utility model protects the foot and lower leg through a foot support plate and a leg bracket, while allowing flexion and extension movements at the ankle. At the same time, the limiting device restricts the rotation between the foot support plate and the leg bracket, thereby fixing the lower leg and foot to prevent the patient from over-moving the ankle and helping the ankle wound to heal. Moreover, the limiting device can be manually released from the rotation restriction between the foot support plate and the leg bracket when needed, so that the ankle can resume flexion and extension movements.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 The present invention provides a specific embodiment of an adjustable angle diabetic foot protection device, including a foot support plate 1 and a leg support 2.

[0022] The foot support plate 1 is a plate-shaped structure that conforms to the shape of the foot. Multiple foot straps 13 are provided on both sides of the foot support plate 1 to fix the foot support plate 1 to the patient's foot.

[0023] One end of the leg support 2 is rotatably connected to the foot support plate 1. The leg support 2 is provided with a leg strap 21 for fixing the leg support 2 to the patient's lower leg, so that the leg support 2 and the foot support plate 1 form an integrated structure for fixing the lower leg and foot. The foot support plate 1 is rotatably connected to the end of the leg support 2. The connection between the foot support plate 1 and the leg support 2 corresponds to the patient's ankle. The rotation direction of the foot support plate 1 relative to the leg support 2 is consistent with the direction of the ankle's flexion and extension movements. This allows the patient to freely flex and extend their ankle when wearing the protective device, making it easy to move their ankle.

[0024] A limiting device 5 is provided at the connection between the foot support plate 1 and the leg support 2 to restrict the rotation between the foot support plate 1 and the leg support 2, so as to fix the patient's foot as a whole and prevent the patient from pulling on the ulcer when moving the ankle, thus affecting the wound healing; and the restriction can be manually released after the ulcer improves, so that the patient can resume flexion and extension movements of the ankle.

[0025] In this embodiment, the following example is provided for the foot support plate 1: like Figure 1 As shown, the foot support plate 1 has a vertical plate 11 on its periphery to form a foot groove 14 for fixing the foot, and the plate 11 also serves a protective function; the foot support plate 1 has a toe cap 12 structure at the position corresponding to the toes to protect the patient's toes.

[0026] In this embodiment, the following example is provided for the rotating structure between the foot support plate 1 and the leg support 2: like Figure 1 As shown, the foot support plate 1 is symmetrically provided with two sets of first connecting members 3 at the position where it connects with the leg support 2, and the leg support 2 is symmetrically provided with two sets of second connecting members 4 at the position where it connects with the foot support plate 1. The two sets of first connecting members 3 are connected to the two sets of second connecting members 4 respectively via a rotating shaft 341 to realize the rotational connection between the foot support plate 1 and the leg support 2.

[0027] Preferably, the rotating shaft 341 is vertically mounted on the first connecting member 3 and integrally formed with the first connecting member 3 to simplify the structure and facilitate processing and installation. The limiting device 5 is preferably disposed on the second connecting member 4.

[0028] This embodiment provides the following example for the limiting device 5: like Figure 2 and Figure 3 As shown, the first connector 3 has a plurality of first limiting holes 31 evenly distributed around the rotating shaft 341, and the second connector 4 has at least one second limiting hole. The distance between the first limiting hole 31 and the rotating shaft 341 is the same as the distance between the second limiting hole and the rotating shaft 341.

[0029] During the relative rotation of the foot support plate 1 with respect to the leg bracket 2, the first limiting hole 31 and the second limiting hole are connected. The limiting device 5 passes through the first limiting hole 31 and the second limiting hole at the same time to achieve relative fixation of the first connecting piece 3 and the second connecting piece 4.

[0030] The limiting device 5 includes a limiting plate 51, a rotating shaft 341 extending outward from one end near the second connecting member 4 to form a limiting shaft 53, a through hole at the center of the limiting plate 51, the limiting shaft 53 passing through the through hole of the limiting plate 51, and the limiting plate 51 being able to move along the limiting shaft 53; a limiting post 52 is provided perpendicularly on the side of the limiting plate 51 facing the second connecting member, and the limiting post 52 can pass through the second limiting hole and the first limiting hole 31 in sequence during the process of the limiting plate 51 moving towards the second connecting member 4.

[0031] Specifically, when it is necessary to fix the foot support plate 1 and the leg bracket 2, the ankle is first flexed and extended to rotate the foot support plate 1 relative to the leg bracket 2 and adjust it to a suitable position so that the first limiting hole 31 and the second limiting hole are connected; then the limiting plate 51 is pressed so that the limiting post 52 passes through the second limiting hole and the first limiting hole 31 in sequence, thereby achieving relative fixation of the first connecting piece 3 and the second connecting piece 4.

[0032] Preferably, two second limiting holes are symmetrically provided on the second connecting member 4 to improve the stability of the limiting shaft 53.

[0033] Furthermore, a spring 54 is sleeved between the limiting plate 51 and the second connecting member 4 on the limiting shaft 53. The spring 54 is used to apply a spring force away from the second connecting member 4 to the limiting plate 51 when the limiting device 5 releases the applied restriction, so that the limiting post 52 is at least disengaged from the first limiting hole 31.

[0034] Furthermore, the end of the limiting shaft 53 is a threaded part, and a force-applying member 55 is threadedly connected to the threaded part. By rotating the force-applying member 55, an external force that counteracts the elastic force is applied during the process of the limiting plate 51 moving toward the second connecting member 4, and this external force is removed during the process of the limiting plate 51 moving away from the second connecting member 4.

[0035] Specifically, after the limiting plate 51 is pressed and fixed, the force-applying component 55 is rotated so that the force-applying component 55 abuts against the limiting plate 51, thereby restricting the limiting plate 51 and keeping it in a pressed and fixed state, thus fixing the foot support plate 1 and the leg bracket 2 relative to each other.

[0036] When the ankle needs to be moved, the force-applying component 55 is rotated in the opposite direction. The force-applying component 55 no longer restricts the limiting plate 51. Under the action of the spring 54, the limiting plate 51 is released away from the second connecting component 4, and the limiting post 52 is disengaged from the first limiting hole 31, so that the foot support plate 1 and the leg bracket 2 return to the rotating state.

[0037] To facilitate wearing this device, the following embodiments are also provided in this implementation: like Figure 1 As shown, one end of the instep strap 13 is fixedly connected to the foot support plate 1, and the other end of the instep strap 13 is detachably connected to the foot support plate 1; one end of the leg strap 21 is fixedly connected to the leg bracket 2, and the other end of the leg strap 21 is detachably connected to the leg bracket 2.

[0038] The detachable connection between the instep strap 13 and the foot support plate 1, and the detachable connection between the leg strap 21 and the leg bracket 2, are preferably achieved through buckles.

[0039] To better protect against diabetic foot, this implementation method also provides the following examples: like Figure 1 As shown, the inner sides of the foot support plate 1, the upright plate 11, the toe cap 12, and the instep strap 13 are all covered with a soft, breathable, and elastic material; the inner sides of the leg support 2 and the leg strap 21 are also covered with a soft, breathable, and elastic material. The preferred material for the covering is medical-grade silicone.

[0040] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
