[0002] Diabetic foot is one of the common complications of diabetic patients, mainly due to neuropathy and vascular disease caused by long-term high blood sugar. Symptoms of diabetic foot include paresthesia, pain, ulcers, infection, etc., which may lead to amputation in severe cases. Treatments for diabetic foot include controlling blood sugar, maintaining foot hygiene, regularly checking foot conditions, wearing appropriate shoes and socks, and performing regular foot massages. The key to preventing diabetic foot is to maintain good blood sugar control, regularly check foot conditions, and perform regular foot care. The diabetic foot protection device is a device specially designed for the prevention and management of diabetic foot, which aims to reduce the risk of foot injuries, infections and ulcers and improve the quality of life of patients.
