EISCO Lung Function Demonstration Model, 13-Inch – Lung & Diaphragm Air Flow Visualization

Discover a tangible way to explore respiratory mechanics with the EISCO Lung Function Demonstration Model. At 13 inches, this lightweight teaching tool uses two flexible sacs as lungs, a rubber diaphragm to simulate muscle movement, and a clear plastic chest cavity to reveal air flow patterns. Its simple, durable design supports hands-on learning in classrooms, labs, and home study without complex equipment.

What you will observe

The transparent enclosure lets students watch air move as the lungs inflate and deflate. By gently pulling the bottom rubber section, you can illustrate diaphragm contraction and relaxation, linking muscle action to changes in chest volume. This direct, visual approach complements a wide range of biology and physiology topics without overwhelming setup requirements.

• Two soft sacs mimic lung tissue and demonstrate fill/empty cycles clearly.
• A flexible rubber diaphragm shows how muscle movement relates to air flow.
• The clear housing reveals airflow dynamics within a simple chest cavity model.

How to use

Use the model for instructor demonstrations or student-driven exploration. The steps are straightforward and repeatable for groups of varying sizes.

• Grip the base and gently pull the bottom rubber section to simulate diaphragmatic movement—inhale as the sacs expand.
• Release to show exhalation as the sacs compress and air exits the model.
• Vary the pace to illustrate different breathing rates and observe the corresponding changes in lung expansion.

Durability and versatility

Constructed from high-quality rubber and plastic, the model is built for repeated classroom demonstrations. Its simple setup makes it suitable for a wide range of ages, from elementary learners to university students, and it adapts well to different room layouts and lab activities.

Real-world learning scenarios

Ideal for science fairs, lab sessions, tutoring, and outreach events, this model provides a concrete reference for respiratory concepts and anatomy fundamentals.

• Elementary to university audiences with approachable, hands-on visuals.
• Supports demonstrations in biology, anatomy, and physiology curricula.
• Fits standard classroom spaces for quick, repeatable lessons.

With its approachable design and tangible visuals, the EISCO Lung Function Demonstration Model invites learners to observe and discuss breathing concepts in a practical, low-pressure setting.
