A simulation model for simulating lung inflation in the human body

Abstract

This invention discloses a simulation model for inflating and supplementing the lungs, relating to the field of lung simulation model technology. The invention includes a simulated human trachea, the surface of which is covered with lung lobe-shaped foamed tissue, the surface of which is covered with visceral pleura. Opening ventilation points are located at the branch ends of the simulated trachea, and through-holes with a diameter of six millimeters are uniformly distributed on the inner wall of the simulated trachea. The branch ends of the trachea are open ventilation points, and the six-millimeter-diameter through-holes on the sidewalls of the trachea allow airflow to enter and exit through different through-holes during ventilation, simulating the stepwise expansion effect of lung lobe ventilation and the gradual collapse effect during exhaust. The space between the trachea and the pleura is filled with biomaterial foamed tissue. The extensibility of this foamed structure is similar to the elasticity of lung tissue, and the volume changes during model expansion and collapse are consistent with surgical results, thereby achieving the training purpose.
