Abstract
A physical lung model (PLM) for training and teaching comprising a lung compartment which is delimited by an enlargeable and reducible piston for enlarging and reducing the volume of the lung compartment, a lid sealing a first end of the piston, a support body carrying the piston in that a second end of the piston is sealingly attached to the support body; and an airway leading from the lung compartment to an airway opening.A mechanical stop is attached to the piston and partitions the piston into a first enlargeable and reducible section and a second enlargeable and reducible section, the mechanical stop describing a path of movement during the enlargement of the lung compartment. A lever, is installed for blocking the movement of the stop at a predefined point on the path of movement during enlargement of the lung compartment and restricting the enlargement of the lung compartment.
