Abstract:
A self-regulating, simulated lung for use in real time in simulated medical procedures comprises at least one bellows capable of receiving and expelling gas, a means for actuating the bellows depending upon a time- and event-based script, a computer model or a combination thereof, at least one mass flow controller capable of directing the gas into the bellows, and a volumetric pump for continuously expelling a constant flow rate of gas from the bellows. The means for actuating the bellows comprises a double acting piston connected to the bellows and having a first constant pressure and a second variable pressure acting on respective sides of the piston, whereby non-linear compliances may be simulated.
