Abstract:
1. A device for simulating variable lung compliance comprising: a structure having two main components between which an artificial lung is situated; the two main components being adapted to be moved away from each other by the artificial lung when the artificial lung is inflated and adapted to move towards one another to force air out of the artificial lung in an exhalation phase; a biasing member selectively attachable between the two main components to provide a force that acts to move the two main components towards one another; a holding mechanism comprising a gripper actuatable by an actuator to move the gripper between a gripping position attaching the biasing member to the two main components and a release position disconnecting the biasing member from the two main components; and wherein the gripper comprises a hook with an inclined face facing a spring and an undercut adjacent to the inclined face, and the inclined face is adapted to abut a loop on the biasing member and guide the loop into the undercut so that the loop is caught in the undercut.
