Oscillating positive expiratory pressure device
First Claim
1. A respiratory treatment device, comprising:
- a housing enclosing at least one chamber;
a chamber inlet configured to receive exhaled air into the at least one chamber;
a mouthpiece in communication with the chamber inlet;
a first aperture formed in the mouthpiece;
a first regulator moveable relative to the first aperture to selectively block a cross-sectional area of the first aperture, wherein the first regulator is moveable relative to the first aperture in a first direction to selectively decrease the cross-sectional area of the first aperture, and movable in a second direction to selectively increase the cross-sectional area of the first aperture;
a flow path defined between the mouthpiece and the first aperture, wherein the flow path does not pass through the chamber inlet; and
,a second aperture formed in the at least one chamber;
a second regulator moveable relative to the second aperture to selectively block a cross-sectional area of the second aperture, wherein the second regulator is moveable relative to the second aperture in a first direction to selectively decrease the cross-sectional area of the second aperture, and movable in a second direction to selectively increase the cross-sectional area of the second aperture;
wherein the mouthpiece is in fluid communication through the first aperture with air surrounding the device.

Abstract
A respiratory treatment device comprising at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, at least one chamber outlet configured to permit exhaled air to exit the at least one chamber, and an exhalation flow path defined between the chamber inlet and the at least one chamber outlet. A restrictor member positioned in the exhalation flow path is moveable between a closed position, where a flow of exhaled air along the exhalation flow path is restricted, and an open position, where the flow of exhaled air along the exhalation flow path is less restricted. A vane in fluid communication with the exhalation flow path is operatively connected to the restrictor member and is configured to reciprocate between a first position and a second position in response to the flow of exhaled air along the exhalation flow path.

10. A respiratory treatment device, comprising:
-
a housing enclosing a chamber; a patient port for transmitting air exhaled from the patient into the chamber and air inhaled by the patient; a chamber outlet configured to permit exhaled air to exit the chamber; an exhalation flow path defined between the patient port and the chamber outlet; a restrictor member positioned in the chamber along the exhalation flow path, the restrictor member moveable in response to the flow of air along the exhalation flow path between a closed position, where the flow of air along the exhalation flow path is restricted, and an open position, where the flow of air along the exhalation flow path is less restricted; and
,a first aperture positioned along the exhalation flow path prior to the restrictor member; a first regulator moveable relative to the aperture to selectively block a cross-sectional area of the aperture, wherein the regulator translates relative to the aperture in a first direction to selectively decrease the cross-sectional area of the aperture, and translates in a second direction to selectively increase the cross-sectional area of the aperture; a second aperture formed in the chamber; a second regulator moveable relative to the second aperture to selectively block a cross-sectional area of the second aperture, wherein the second regulator is moveable relative to the second aperture in a first direction to selectively decrease the cross-sectional area of the second aperture, and movable in a second direction to selectively increase the cross-sectional area of the second aperture; wherein the patient port is in fluid communication through the first aperture with air surrounding the device. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of performing respiratory treatment, the method comprising:
-
passing a flow of exhaled air along an exhalation flow path defined between a patient port and an outlet of an oscillating positive expiratory pressure device; moving a restrictor member in response to the flow of exhaled air between a closed position, where the flow of exhaled air along the exhalation flow path is restricted, and an open position, where the flow of exhaled air along the exhalation flow path is less restricted; and
,selectively moving a first regulator relative to a first aperture positioned along the exhalation flow path prior to the restrictor member, wherein the first regulator moves relative to the first aperture in a first direction to selectively decrease a cross-sectional area of the first aperture, and moves in a second direction to selectively increase the cross-sectional area of the first aperture; selectively moving a second regulator relative to a second aperture positioned along the exhalation flow path after the restrictor member, wherein the second regulator moves relative to the second aperture in a first direction to selectively decrease a cross-sectional area of the second aperture, and moves in a second direction to selectively increase the cross-sectional area of the second aperture. - View Dependent Claims (18, 19, 20, 21)
