<p>A respiratory therapy device including a housing and an interrupter valve assembly. The housing includes a patient inlet, an exhaust outlet, a chamber, and a supply inlet. The interrupter valve assembly is associated with the housing and includes a control port fluidly connecting the patient inlet and the first chamber, and a valve body adapted to selectively obstruct fluid flow through the control port. In a passive mode, positive fluid flow to the supply inlet does not occur, and the interrupter valve assembly interacts with exhaled air create an oscillatory PEP effect. In an active mode, fluid flow to the supply inlet occurs and the interrupter valve assembly operates to create a CHFO effect. The respiratory device can serve as a passive oscillatory PEP device, and when connected to a positive pressure source, as an active device.</p> |
