Description

Technical Field

[0001] The utility model relates to a diabetic foot negative pressure closed decompression brace, belonging to the field of medical care. Background Art

[0002] Diabetic foot is caused by multiple factors such as vascular disease, pressure injury and infection, resulting in ischemic necrosis of the skin, infection and ulceration. It does not heal for a long time and requires long-term dressing changes. For some patients, the soles of the feet are compressed due to gravity, or the sides of the feet are compressed due to wearing shoes that are too tight, resulting in lesions corresponding to the pressure points of the feet. Reducing the pressure on the lesions is the fundamental treatment and prevention measure. Different patients have different pressure points on the skin and different lesion sites. The diabetic foot looks bloated after being bandaged with dressings. If there is no suitable foot decompression brace, patients either walk barefoot or in huge slippers, or wear ordinary shoes, which causes the lesions to continue to be compressed and not heal, seriously affecting their quality of life.

[0003] At present, the decompression methods for diabetic foot in clinical practice are generally designed to reduce pressure by increasing the contact area of ​​the sole of the foot, but they cannot fundamentally reduce the overall pressure. They mainly include decompression plaster, decompression brace, decompression shoes, etc. Among them, decompression plaster can be adjusted according to the lesion site and dressing size, but it is troublesome to maintain. Although decompression brace and decompression shoes are easy to wear, they are single in model and incompatible with dressings, and cannot be suitable for all patients. At the same time, these decompression products cannot promptly and effectively treat wound exudate, are easily contaminated, and affect long-term use. Utility Model Content

[0014] The utility model integrates the plantar decompression mechanism and the negative pressure drainage mechanism into a set of negative pressure closed decompression brace, which simultaneously performs the three functions of wound repair, plantar decompression and walking. It allows diabetic foot patients to be discharged from the hospital with their wounds, greatly shortening the hospitalization period, allowing patients to receive treatment at home, achieving exercise rehabilitation and wound repair at the same time, and greatly improving the quality of life with the disease.

[0015] The utility model adopts the design of two hinges, so that the leg decompression bracket and the foot decompression shoe can be movably connected, thereby meeting the basic walking function of the device, and at the same time, the gravity is transmitted to the foot decompression shoe through the leg decompression bracket and finally to the ground.

[0016] The utility model can timely remove the exudate produced by the wound surface through the design of the negative pressure drainage mechanism, thereby promoting the healing of the wound without causing pollution.

[0017] The utility model covers the foot of the diabetic patient with the dressing inside the sealing film by putting the sealing film on the foot of the diabetic patient. In this way, while the dressing can treat the foot of the diabetic patient, the exudate generated by the foot of the diabetic patient can be gathered inside the sealing film without causing pollution. At the same time, the exudate generated can be collected and processed by the negative pressure drainage mechanism.

[0018] The utility model adopts the decomposable structure design of the leg decompression bracket, so that the leg decompression bracket can be quickly matched with the leg and is convenient to disassemble and install.

[0019] The utility model, through the design of the hinge, can facilitate the movement of the foot decompression shoe and the leg decompression bracket, and can also transfer the weight of the leg decompression bracket to the foot decompression shoe, and then transfer it to the ground through the foot decompression shoe, thereby reducing the pressure on the foot of the diabetic patient.
