Human Lung Model with Visible Inflation and Manual Diaphragm Control for Classroom Teaching

Human Lung Model with Visible Inflation and Manual Diaphragm Control for Classroom Teaching Description

Product overview This educational respiratory model demonstrates the relationship between changes in thoracic cavity volume and diaphragm movement. It provides a clear, hands on way for students to observe how diaphragm motion affects lung inflation and deflation. Key benefits Makes respiratory mechanics visible and intuitive by linking diaphragm movement to lung volume change. Simple manual operation allows repeated demonstrations and student interaction. Clear construction enables unobstructed observation of lung behavior during inflation and deflation. Main components and materials Transparent plastic container that forms the simulated thoracic cavity. Elastic rubber bottom that acts as a movable diaphragm. Rubber plug fitted with an inverted Y shaped trachea made of transparent plastic to connect two lung lobes. Two lung lobe models that inflate and deflate through the trachea. How it works Inflate: Before use, remove the rubber bottom, gently blow air through the inverted Y shaped trachea to slightly fill the lung lobes, then the rubber bottom so the container is closed while the lobes remain open to outside air. Simulate diaphragm contraction: Pull down the center of the elastic rubber bottom. This increases the internal volume of the container and the lung lobes visibly expand. Simulate diaphragm relaxation and positive pressure: Release the rubber bottom and the lungs to the slightly inflated starting state. Push the rubber bottom upward to reduce cavity volume and the lung lobes contract. Features and performance Visual transparency: Clear container and trachea allow direct observation of lung behavior and airflow path. Durable, elastic diaphragm: The rubber bottom provides repeated, reliable movement to model diaphragm action. Easy setup and reset: Manual controls let instructors and students perform multiple demonstrations in quick succession. Suitable uses and scenarios Classroom demonstration: Use during lectures on respiratory physiology to show cause and effect between diaphragm motion and lung volume. Laboratory practicals: Include as a hands on station for small group exercises where students operate the model themselves. Exam preparation and review: Use as a study aid to reinforce understanding of ventilation mechanics and basic respiratory concepts. Notes on compatibility and handling Intended for educational and demonstration use in classroom and laboratory settings. No external equipment required beyond simple manual operation and minimal handling to inflate the lung lobes. Handle the rubber components gently to prolong service life and ensure repeated, consistent operation.
