Patent ID: 7096866

Claim:
An inexsufflator for cough simulation to remove broncho-pulmonary secretions of a patient comprising: a patient interface unit configured to permit fluid flow therethrough at a flow rate of at least 160 liters/minute; a source of negative fluid pressure configured to generate the flow rate of at least 160 liters/minute; and a valve in communication with the patient interface unit, a port of the source of negative fluid pressure, and a port of a ventilator, said valve configured to selectively connect said patient interface unit with one of said port of said ventilator and said port of said source of negative fluid pressure and to selectively seal fluid flow between said patient interface unit and one of said port of the ventilator and said port of said source of negative fluid pressure, wherein actuation of the valve from a first position to a second position at or near lung capacity of the patient initiates exsufflation of the lung to simulate a cough.
