Pathological anatomical model of mouth, nasal cavity, pharynx, and larynx Key benefits Accurate visualization of pathological changes: Shows detailed pathological anatomy of the mouth, nasal cavity, pharynx, and larynx so users can identify and compare common diseaserelated changes. fidelity, realistic presentation: Nasal cavity and related structures are remodeled from real human anatomy for clear, lifelike representation that supports teaching and explanation. Clear labeling for explanation: Includes a digital /labeling to make structures easy to identify and explain during demonstrations. Durable and safe materials: Pharynx component is made of PVC — corrosionresistant, lightweight, and of peculiar odors, providing a safe, healthy synthetic material for repeated handling. Longlasting, easy to observe: Advanced, colorfast finishing makes anatomical features distinct and resistant to fading, extending usable life. Function and performance Purpose: Demonstrates pathological anatomy and structural relationships of the upper respiratory and upper digestive tract (mouth, nasal cavity, pharynx, larynx) for education and clinical explanation. Fidelity: Realhuman remodeling provides visual accuracy for anatomy and pathology comparisons. Durability: Corrosionresistant PVC and colorfast surface ensure stable appearance and low maintenance over longterm use. Usability: Clear visual contrast and digital /labels allow quick identification and straightforward explanation to students, patients, or colleagues. Material and care Material: Pharynx and related removable components constructed from PVC synthetic material. Properties: Lightweight, corrosionresistant, odorless in normal use. Care: Wipe with a soft cloth and mild disinfectant; avoid strong solvents or prolonged exposure to direct sunlight to preserve color. Typical applications (use scenarios) Medical and nursing education: Use in classroom demonstrations, labs, and practical exams to teach pathological changes and upper airway anatomy. ENT clinics and patient consultations: Explain diagnoses and treatment options to patients by showing reallife anatomical changes and locations of pathology. Training and continuing education: Support handson training for clinicians and allied health professionals in identifying and discussing common pathologies of the nasal cavity, pharynx, and larynx. What makes this model stand out Combines realistic human remodeling with clear digital labeling for effective teaching and communication. Constructed from safe, corrosionresistant PVC with colorfast finishes for reliable, longterm use. Designed specifically to illustrate pathological changes across mouth, nasal cavity, pharynx, and larynx for practical clinical and educational value.
