APPARATUS FOR ADMINISTERING INTERMITTENT PERCUSSIVE VENTILATION AND UNITARY BREATHING HEAD ASSEMBLY FOR USE THEREIN

摘要

A unitary breathing head device for administering intermittent percussive ventilation to a patient having an airway and for use with an IPV device (16) having a source of continuous gas flow and having a source of pulsed gases comprising a combination injector and exhalation valve assembly (12) comprising a main body (26) having an airway port for communication with the airway of the patient and having proximal (27) and distal extremities (28) and a flow passage (29) extending from the proximal extremity to the distal extremity. The main body has a depending portion forming a plenum chamber (82) in communication with the flow passage in the main body. A nebulizer (13) is removably secured to the depending portion of the main body and has a nebulizer chamber in communication with the plenum chamber. The depending portion of the main body and the nebulizer form a handle adapted to be gripped by the hand of the patient holding the breathing head assembly.
