A new glass-bottle model of lung simulator has been established

aiming to test the ventilator. It was proved that the compliance of lung simulator was related to the volume and the inside temperature of the glass- bottle theoretically. The feasibility of the model was proved by some related experiments . The research shows that under the condition of constant temperature

the compliance of the lung simulator is related to the volume of the glass-bottle

the temperature inside the glass-bottle could be kept constant under a certain frequency if some copper wool was put into the glass-bottle

and the lung simulator could be used to accurately test the performance of the ventilator.
