A lung simulation system has been granted a patent (Publication Number: US11842654B2) that includes a lung simulator and an airway resistance device. The airway resistance device comprises a body with an airtight internal chamber, an inlet, and an outlet. The device also includes a variable occlusion mechanism that can selectively vary the width, length, and number of laminar flow channels to adjust the simulated airway resistance. The occlusion mechanism includes various configurations such as a plug, a bullet-shaped plug, or a displaceable sidewall, each connected to a control mechanism for adjustment. Additionally, the system includes a sensor system to measure lung inflation and deflation, with a controller providing dynamic control to the airway resistance device based on the measured state.

Furthermore, the patent also covers a method for simulating lungs using the described airway resistance device connected to a lung simulator. The method involves adjusting the control mechanism of the occlusion mechanism to achieve the desired airway resistance for the simulation. A source of respiration airflow is then applied to the lung simulator through the airway resistance device, causing a pressure drop proportional to the airflow. The method allows for simulating different levels of airway resistance by adjusting the control mechanism during the simulation, providing a realistic and dynamic lung simulation experience for various applications in the medical and research fields.
