★Two-stage model: Mild lesions (Stages 1–3) or severe lesions (Stages 4–5). This model is rigorously designed based on authentic diabetic foot pathology data, accurately depicting mild symptoms (dry skin/callus formation) and severe ulcer progression (tissue necrosis/exposed bone), ensuring precision in medical education. ★Side-by-Side Pathology Comparison: The mild model displays early warning signs, while the severe model reveals late-stage complications. This comparative learning approach helps students grasp disease mechanisms. ★Diabetic Foot Model: Realistically replicates human foot anatomy. Pressing simulates the firmness and resistance of actual edema areas; touching wounds provides an immersive tactile experience with rough scabs and uneven tissue damage. ★Material: Crafted from food-grade silicone, odorless and hypoallergenic. Effectively simulates diabetic foot ulcers, infections, and necrotic tissue at varying stages, enabling students to intuitively grasp pathological characteristics. ★Applications: Suitable for medical schools, hospitals, emergency training centers, and patient education. Empowers healthcare professionals and patients to master diagnostic and nursing techniques across diabetic foot progression stages, meeting clinical teaching and patient demonstration needs.
