Description

Technical Field

[0001] The present invention relates to the field of intelligent medical technology, and more specifically, to a method, system and device for diabetic wound image analysis and intelligent rehabilitation. Background Art

[0002] Wound healing is a complex biological process, in which multiple factors such as inflammatory cells, repair cells, extracellular matrix and cytokines participate in, coordinate and regulate each other. The skin of diabetic patients is easily damaged, and the damage often recurs, persists and does not heal, forming stubborn and difficult-to-heal ulcers. This is mainly because the tissue cells of diabetic patients are in a high-sugar environment for a long time, which makes local skin tissue cells and proteins glycosylated, causing vascular endothelial dysfunction and impaired response; macrophage dysfunction, prolonged and unbalanced inflammatory response; lack or damage of growth factors, reduction of gelatin tissue, disorder of epidermal barrier function, and reduction of granulation tissue, which make the wound difficult to repair.
