Interactive Lung Breathing Simulator Teaching Model Key Benefits Demonstrates how the lungs and diaphragm work together to move air and simulate breathing, making respiratory mechanics easy to visualize. Transparent components and detachable lung lobes reveal internal structure and movement, supporting handson learning and clear explanations. Compact and durable construction allows repeated classroom use and simple transport between demonstrations. What the Model Shows The simulator consists of two elastic sacs that represent the lungs, a rubber membrane that acts as the diaphragm, and a Y shaped transparent trachea that divides airflow to both lungs. Pulling the elastic base or rubber membrane changes internal pressure and shows the lungs expanding and contracting, illustrating the basic principle of inhalation and exhalation. Detachable lung lobes and a thickened outer cover provide realistic appearance and permit detailed examination of lung anatomy. Construction and Materials Components: transparent container, elastic base, rubber stopper with Y shaped transparent trachea, and lung lobe models. Materials: polypropylene and rubber for durability and flexible movement. Size: 10 x 21 cm (3.94 x 8.27 inch). Package includes: 1 Lung Teaching Model Toy. Why this Model Stands Out Clear, transparent design makes internal motion visible without disassembly, helping teachers and students connect concept to observation. Removable lung lobes and robust rubber parts allow repeated handling during lessons while maintaining structural detail. Simple operation requires no tools or power, enabling quick setup and straightforward demonstrations. Typical Use Scenarios Classroom demonstration: Teachers use the model to show students how changes in diaphragm position affect lung volume and airflow during a live lesson. Laboratory or training session: Small groups can examine the detachable lobes and practice explaining gas movement between the lungs and the external environment. Home schooling or study: Students use the compact model for handson review of respiratory anatomy and basic breathing mechanics. How to Use Place the lung sacs inside the transparent container and secure the rubber stopper with the Y shaped trachea. Pull the bottom elastic section or press the rubber membrane to simulate diaphragm movement and observe lungs inflate and deflate. Remove lung lobes for closer inspection and to demonstrate detailed structural features. This lung teaching model provides a clear, durable, and easy to use tool for visualizing breathing mechanics and supporting interactive lessons on respiratory structure and function.
