A model for demonstrating human lung function

MACHINE TRANSLATION (not authorised yet)

A educational model demonstrating the mechanism of human lung respiration. The educational aid consists of a transparent lamp shade with two balloons hanging inside it fixed on an inverted Y-shaped connector. The diffuser is attached to a base with a built-in membrane with a handle. By pulling out and filling the membrane and releasing it, we demonstrate and explain the mechanism of inhalation and exhalation and the expansion of the chest and lungs during the inflow of air into the lungs.
