Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a support brace for diabetic foot. Background Technology

[0002] Diabetic foot is one of the most serious and disabling chronic complications of diabetes. It is caused by long-term hyperglycemia, leading to peripheral neuropathy and peripheral vascular disease in the lower extremities. Under the combined effects of local pressure, friction, and infection, it results in skin ulcers, deep tissue damage, and even gangrene in the foot. In severe cases, amputation is required, significantly reducing the patient's quality of life and increasing the social medical burden. The core pathological features of diabetic foot are: peripheral neuropathy causes a significant reduction or even loss of pain, pressure, and temperature sensation in the foot, making it impossible for patients to perceive abnormal pressure and minor injuries; peripheral vascular disease leads to insufficient blood supply to the foot, and a significant decrease in tissue repair and anti-infection capabilities. On this basis, the concentrated, continuous pressure or shear force on the sole of the foot caused by walking and standing can easily cause skin breakdown and rapidly develop into refractory ulcers. These ulcers are difficult to heal and are prone to recurrence. Clinical and biomechanical studies have confirmed that abnormal local pressure is a key mechanical factor that induces and aggravates diabetic foot ulcers. Conventional footwear and ordinary insoles cannot effectively distribute pressure and relieve pressure on the affected area. On the contrary, they can easily aggravate tissue damage due to uneven force and excessive local pressure.

[0003] To reduce the risk of foot compression, protect ulcer wounds, and allow patients to walk safely, there is an urgent need for specialized diabetic foot support and decompression devices. Through reasonable mechanical support and pressure redistribution, these devices can reduce the compression and friction on fragile foot tissues during walking, improve the walking safety and comfort of diabetic foot patients, and reduce the incidence of ulcers and the risk of amputation. Existing support and decompression products still have shortcomings in terms of adaptability and dynamic pressure regulation. They often simply distribute pressure to the ankle or knee, which is difficult to meet the comprehensive needs of reliable support, all-area decompression, and conformity to walking habits. Therefore, developing an auxiliary walking support device with a reasonable structure, stable support, effective decompression, and adaptability to the pathological characteristics of diabetic foot has important clinical value and practical necessity. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a special support brace for diabetic foot, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a special support brace for diabetic foot, including a control groove, an adjusting block, a support telescopic rod, an ankle groove and a pressure mechanism. The control groove is symmetrically arranged and includes a sliding groove. The adjusting block is linearly arrayed in the sliding groove. The bottom end of the support telescopic rod is rotatably disposed in the adjusting block. The ankle groove is disposed at the top end of the support telescopic rod. The pressure mechanism is disposed outside the sliding groove.

[0006] Furthermore, the control slot is provided with a pedal on the opposite side of the other control slot, and a strap is provided at the front end and rear end of the control slot respectively. The strap is connected to the control slot, and the patient can place the control slot on both sides of a single shoe, step on it with the pedal, and secure it with the strap.

[0007] Furthermore, the adjusting block includes a slider with a spherical groove inside. A pre-drilled opening is provided through the top wall of the spherical groove. An adjusting mechanism is provided between the sliders. The adjusting mechanism includes a threaded sleeve and a screw. The screw is located inside the threaded sleeve, and the threaded sleeve and screw are threadedly engaged. The threaded sleeve is rotatably mounted on one side of the slider, and the screw is mounted on the other side of the slider. The threaded sleeve communicates with the spherical groove inside the connected slider. The screw is hollow and communicates with the spherical groove inside the connected slider. An adjusting plate is provided on the outer wall of the threaded sleeve. Rotating the adjusting plate allows the threaded sleeve to rotate, thereby adjusting the position of the slider.

[0008] The control slot is equipped with a connecting pipe, which communicates with the spherical groove in the nearest slider.

[0009] Furthermore, the support telescopic rod includes a sleeve and a sliding rod. The bottom end of the sleeve is inserted into a spherical groove. The portion of the sleeve located in the spherical groove is symmetrically provided with arc-shaped plates. The arc-shaped plates are in contact with the inner wall of the spherical groove. An air hole is also provided at the bottom end of the sleeve. The sliding rod is slidably disposed on the inner side of the sleeve.

[0010] Furthermore, the end of the sliding rod is provided with a ball head, and the side wall of the ankle groove is provided with a slot. The ball head is locked in the slot. The ankle groove is provided with a second strap, which connects the two ankle grooves. The patient can flexibly adjust the position of the ankle groove by the flexible sliding of the slider and the double-end hinge of the support telescopic rod, so that the ankle groove fits against the two sides of the ankle and is tightly fixed by the second strap.

[0011] Furthermore, the pressure mechanism provides air pressure to the spherical groove and the supporting telescopic rod. An air pipe is provided between the pressure mechanism and the connecting pipe. The main structure of the pressure mechanism is a common air pump on the market, which will not be described in detail here. The pressure mechanism can be fixed to the leg or placed in a pocket or backpack according to actual needs.

[0012] The beneficial effects of the present invention using the above structure are as follows: The diabetic foot support brace provided by this solution allows for flexible installation and removal from the patient's shoe through a strap connection structure. Simultaneously, the adjustable adjustment block, combined with the telescopic support rods and the double-end hinged structure, allows the ankle groove to be flexibly adjusted according to the patient's foot shape, conforming to the protruding parts on both sides of the ankle. Furthermore, the pressure mechanism can adjust the support strength according to the patient's weight or needs, flexibly adjusting the foot pressure distribution. Compared to traditional ankle and knee support structures that only provide maximum support when standing still, this invention achieves multi-directional support through multiple telescopic support rods. It can provide stable longitudinal support by adapting to changes in the foot's contact angle with the ground caused by the forward and backward movement of the ankle during actual walking, effectively improving the support effect.

The bottom end of the support telescopic rod 3 is rotatably disposed in the adjusting block 2. The ankle groove 4 is disposed at the top end of the support telescopic rod 3. The pressure mechanism 5 is disposed on the outside of the sliding groove 101.

[0020] A pedal 103 is provided on the opposite side of the control slot 1 and another control slot 1. A strap 102 is provided at the front end and the rear end of the control slot 1 respectively. The strap 102 is connected to the control slot 1. The patient can place the control slot 1 on both sides of a single shoe, step on it with the pedal 103 and tighten it with the strap 102.

[0021] The adjusting block 2 includes a slider 201, with a spherical groove 202 inside the slider 201. A pre-reserved opening 203 is provided through the top wall of the spherical groove 202. An adjusting mechanism 6 is provided between the sliders 201. The adjusting mechanism 6 includes a threaded sleeve 601 and a screw 603. The screw 603 is located inside the threaded sleeve 601, and the threaded sleeve 601 and the screw 603 are threadedly engaged. The threaded sleeve 601 is rotatably mounted on one side of the slider 201, and the screw 603 is mounted on the other side of the slider 201. The threaded sleeve 601 communicates with the spherical groove 202 inside the connected slider 201. The screw 603 is hollow and communicates with the spherical groove 202 inside the connected slider 201. An adjusting plate 602 is provided on the outer wall of the threaded sleeve 601. Rotating the adjusting plate 602 can rotate the threaded sleeve 601, thereby adjusting the position of the slider 201.

[0022] The control slot 1 is provided with a connecting pipe 104, which communicates with the spherical groove 202 in the nearest slider 201 and is fixedly connected to the slider 201.

[0023] The support telescopic rod 3 includes a sleeve 301 and a sliding rod 302. The bottom end of the sleeve 301 is inserted into the spherical groove 202. The part of the sleeve 301 located in the spherical groove 202 is symmetrically provided with an arc plate 304. The arc plate 304 is in contact with the inner wall of the spherical groove 202. An air hole 305 is also opened at the bottom end of the sleeve 301. The sliding rod 302 is slidably disposed on the inner side of the sleeve 301.

[0024] The end of the slide bar 302 is provided with a ball head 303, and the side wall of the ankle groove 4 is provided with a slot 401. The ball head 303 is locked in the slot 401. The ankle groove 4 is provided with a second strap 402, which connects the left and right ankle grooves 4. The patient can flexibly adjust the position of the ankle groove 4 by sliding the slider 201 and hinged at both ends of the support telescopic rod 3, so that the ankle groove 4 fits against the sides of the ankle and is fixed by the second strap 402.

[0025] The pressure mechanism 5 provides air pressure to the spherical groove 202 and the support telescopic rod 3. An air pipe 501 is provided between the pressure mechanism 5 and the connecting pipe 104. The main structure of the pressure mechanism 5 is a common air pump on the market, which will not be described in detail here. The pressure mechanism 5 can be fixed to the leg or placed in a pocket or backpack as needed.

[0026] In practical use, firstly, the pressure mechanism 5 is depressurized. Then, according to the actual condition of the patient's foot, the control groove 1 is placed on both sides of the shoe. The patient steps on the pedal 103 to hold the control groove 1 in place and secures it to the shoe with the first strap 102. The position of the adjusting block 2 is adjusted by rotating the adjusting plate 602 according to the ankle position. Then, the ankle groove 4 is moved to the ankle and fits against it. The control groove 1 and the ankle groove 4 are then secured by the first strap 102 and the second strap 402. Subsequently, the pressure mechanism 5 is pressurized. The pressure is transmitted to the support telescopic rod 3 through the air tube 501, the connecting pipe 104, and the adjusting block 2. The ankle groove 4 provides support for the patient's ankle. The pressure of the pressure mechanism 5 can be adjusted according to the patient's weight or needs, thereby adjusting the support strength and flexibly adjusting the foot pressure distribution. Compared with traditional ankle and knee support structures that can only provide maximum support when standing still, multiple support telescopic rods 3 achieve multi-directional support. When the patient walks, whether the foot rotates forward or backward, there is always a support telescopic rod 3 in a state that is close to perpendicular to the ground, providing longitudinal support for the ankle. It can provide stable support as the foot's contact angle with the ground changes due to the forward and backward movement of the ankle during actual walking.
