Claim 0:
1. A device for treating chest wall injuries, the device comprising:
a frame adapted to be placed external to a chest and fully covering an area of injury to create a localized airtight compartment;
one or more sensors adapted to sense ventilation or chest wall motion in real time,
a pump configured to vary a pressure within the localized airtight compartment,
a controller adapted to interface between a measurement of patient ventilation and the pump, wherein the controller is adapted to control variation of the pressure within the localized airtight compartment external to the chest in real-time so as to provide a dynamic counterforce to the changes in intrathoracic pressure that occur during each ventilatory cycle, the dynamic counterforce minimizing paradoxical motion of chest wall injuries by dynamically counteracting the changes in intrathoracic pressure.
