Abstract:
Apparatus for administering intermittent percussive ventilation to a patient having an airway, comprising an intrapulmonary percussive ventilation device for providing sources of gases under continuous flow and cyclic flow and a unitary breathing head assembly, the assembly comprising an elongate main body having proximal and distal extremities and having a flow passage extending from the proximal extremity to the distal extremity, the main body having an airway port adapted to be placed in communication with the airway of the patient and in communication with the flow passage of the main body, an expiratory port carried by the main body proximally of the airway port, a valve seat formed in the main body and circumscribing the flow passage in the main body, an injector body slidably mounted in the flow passage of the main body and having proximal and distal extremities, the injector body having its distal extremity movable into and out of engagement with the valve seat, the injector body having a passageway extending therethrough from the proximal extremity to the distal extremity, a diaphragm carried by the main body coupled to the injector body having a retracting memory for retaining the injector body in a retracted position with respect to the valve seat, the main body having a depending portion forming a plenum chamber in communication with the flow passage in the main body, a nebulizer having a nebulizer bowl providing a nebulizing chamber therein, cooperative mating means for removably securing the nebulizer body to the depending portion of the main body and establishing communication between the nebulizing chamber and the plenum chamber in the depending portion of the main body, and tubing coupling the intrapulmonary percussive ventilation device to the nebulizer and to the main body for supplying a continuous flow of gas to the nebulizer and a pulsatile flow gas to the main body.
