RESPIRATORY THERAPY DEVICE AND METHOD
First Claim
1. A device for providing respiratory therapy to a patient during at least a portion of a patient breathing cycle including an inspiratory phase and an expiratory phase, the device comprising:
- a housing including a patient inlet, an exhaust outlet, first and second chambers fluidly disposed between the patient inlet and the exhaust outlet, and a first pressurized fluid supply inlet;
an interrupter valve assembly associated with the housing and including 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; and
a control assembly associated with the housing and including a passage connecting the first chamber and the second chamber, the control assembly adapted to selectively open and close the passage.

Abstract
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.

22. A method of providing respiratory therapy to a patient during at least a portion of a patient breathing cycle including an inspiratory phase and an expiratory phase, the method comprising:
-
providing a respiratory therapy device including; a housing including a patient inlet, an exhaust outlet, first and second chambers fluidly disposed between the patient inlet and the exhaust outlet and a pressurized fluid supply inlet, and an interrupter valve assembly for selectively interrupting fluid flow to or from the patient inlet, and a control assembly associated with the housing and including a passage connecting the first chamber and the second chamber; and selectively operating the control assembly to open the passage in a passive mode of operation and close the passage in an active mode of operation. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
