Dynamic structure demonstration Specially developed dynamic demonstration structures visualize the breathing process through practical handling. This model design enhances practicality and interactive learning in educational contexts, helping users understand the core principles of three-dimensional lung function. Reliability and durability The construction uses uniform material density and precision casting technology to ensure durability and stability. The structural design prevents deformation and functional degradation with long-term use, providing reliable, sustainable value for users. Cognitive enhancement A goal-oriented training program is implemented. The model features a unique mechanism that balances logical problem-solving ability with physical reaction rates, supporting cognitive development alongside hands-on learning. Practical learning aid The lung model includes movable parts that enable experimental learning. It is accompanied by teaching materials to acquire basic knowledge in medicine and physiology while manually reproducing breathing movements. Use scenarios - Classroom demonstrations in anatomy or physiology courses to visualize and explore the breathing process with hands-on interaction. - Medical or nursing training laboratories to practice respiration mechanics, perform related experiments, and reinforce understanding of lung function. - Self-guided study or science outreach settings where learners engage with interactive physiology to deepen practical knowledge of respiratory dynamics.
