Abstract
Description
Technical Field
[0001] This utility model relates to the field of diabetes care technology, and in particular to a foot decompression structure for diabetic foot. Background Technology
[0002] Diabetic foot refers to a disease state in diabetic patients where ulcers and gangrene occur due to decreased lower limb protective function caused by neuropathy, and insufficient arterial perfusion caused by macrovascular and microvascular lesions leading to microcirculatory disorders. Diabetic foot is a serious complication of diabetes and one of the important causes of disability and even death in diabetic patients. It not only causes pain to patients but also adds a huge economic burden to them. Diabetic patients' feet need to be protected with decompression structures.
[0003] However, in actual use, when patients walk, the soles of their feet become in close contact with the insoles, and prolonged wear can lead to bacterial growth. This hinders the breathability and pressure relief of the feet, affects the structural protection, and can easily aggravate foot ulcers and bacterial growth, thus affecting subsequent recovery.

[0017] In a preferred embodiment, the buffer block is a breathable foam block, and the buffer block is a regular pentagon with anti-slip texture on its surface.
[0018] The cushioning blocks provide protection for the soles of the feet during use, and also facilitate the installation and removal of the cushioning blocks, thus reducing pressure and protecting ulcerated areas on the soles of the feet.
[0019] In a preferred embodiment, an arc-shaped support strip is fixedly installed on the insole at the arch of the foot, and the surface of the arc-shaped support strip is provided with anti-slip texture.
[0020] The curved support bar provides convenient support for the arch of the foot during use, thereby improving foot comfort.
[0021] In a preferred embodiment, a pressure-reducing block is fixedly installed on the upper surface of the insole at the heel position, and a retaining strip made of silicone is fixedly installed on the inner side of the protective edge.
[0022] The pressure-reducing blocks provide support for the heel during use, thereby improving the comfort of the pressure-reducing structure.
[0023] As can be seen from the above, the foot decompression structure for diabetic foot provided by this utility model has the following technical effects.

A return spring 407 is fixedly installed on the inner bottom wall of the groove. A pressure plate 408 is fixedly installed on the top of the return spring 407. The air component 4, during use, allows the patient's foot to press against the pressure plate 408 at the bottom of the insole 500 while walking, thereby allowing the air in the airbag 400 to be released into the cavity of the shoe, preventing bacterial growth, facilitating ventilation and pressure relief for the foot, and aiding in subsequent recovery. A cushioning ring 402 is fixedly installed on the top of the pressure plate 408. The upper surface of the cushioning ring 402 has anti-slip textures, and the cushioning ring 402 is made of silicone. The cushioning ring 402 facilitates the cushioning and compression of the pressure plate 408 during use, thereby reducing pressure on the sole of the foot. The pressure plate 408 is located above the airbag 400.
[0035] The pressure-reducing component 5 includes an insole 500 placed on a pressure plate 408. A slot is provided on the top of the insole 500, and a cushioning block 501 is engaged inside the slot. The pressure-reducing component 5 reduces pressure on the soles of the feet during use, thus preventing foot injuries during walking and improving the protective performance of the pressure-reducing structure. The cushioning block 501 is made of breathable foam and is a regular pentagon with anti-slip textures on its surface. The cushioning block 501 protects the soles of the feet during use and is also easy to install and remove. For pressure relief protection in areas of sole ulceration, an arc-shaped support strip 502 is fixedly installed on the insole 500 at the arch position. The surface of the arc-shaped support strip 502 has anti-slip texture. The arc-shaped support strip 502 provides convenient support for the arch position during use, thereby improving foot comfort. A pressure relief block 503 is fixedly installed on the upper surface of the insole 500 at the heel position. A retaining strip 8 made of silicone is fixedly installed on the inner side of the protective edge 2. The pressure relief block 503 provides support for the heel during use, thereby improving the comfort of the pressure relief structure.
[0036] Reference Figure 1 and Figure 2In a preferred embodiment, a protective strip 6 is fixedly installed on the upper surface of the protective edge 2. The protective strip 6 is made of silicone. The protective strip 6 is designed to protect the instep during use, making it easier to put on the shoes and preventing them from falling off. An anti-slip block 7 is fixedly installed on the bottom of the sole 1. The lower surface of the anti-slip block 7 has anti-slip textures and is made of rubber. The anti-slip block 7 is designed to prevent slipping during use.
[0037] Working principle: When in use, the foot is put into the pressure-reducing shoe. Then, as the patient walks, the foot is squeezed against the pressure plate 408 at the bottom of the insole 500, which allows the gas in the airbag 400 to be released into the cavity of the shoe, facilitating ventilation and pressure reduction of the foot. When there are ulcerated areas on the sole of the foot and it is necessary to reduce pressure on these areas, the corresponding cushioning block 501 can be removed from the insole 500 to avoid squeezing the injured and ulcerated areas during walking.
