Device for simulating variable lung compliance, comprising a structure having two main components () between which an artificial lung () is situated, the main components () being adapted to be moved away from each other by the lung () when the lung is inflated and are adapted to move towards one another to force air out of the lung () in an exhalation phase; and a biasing means () acting to provide a force that acts to move the two main parts () towards one another. The biasing means comprises at least one spring (), which is selectively attachable to impose the force, upon actuation by a spring holding mechanism ().

Device for simulating variable lung compliance

Medical patient simulator comprising a torso () that contains an artificial lung (), a chest skin () and means () for pulling the chest skin () downward in an area corresponding with an area where such retractions occur on a human being. The simulator also provides for changes in the compliance of the lung (). The lung () is situated between two plates (), the spacing of which can be adjusted. The torso () has one actuator () on each side of the back to simulate muscular activity. It includes a system for control of pneumatic functions by measuring a representative pressure for each actuator and stopping the filling when a pre-set pressure is reached. It also includes a head with one or more air cushions in a fontanelle area on the head, which may be filled with air to simulate an increased pressure in the brain.
