Oscillating positive expiratory pressure device
First Claim
1. A respiratory treatment device comprising:
- an inlet configured to receive exhaled air into the device;
an outlet configured to permit exhaled air to exit the device;
an exhalation flow path defined between the inlet and the outlet;
an oscillation member moveable along a central axis of the oscillation member 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 air along the exhalation flow path is less restricted; and
,a plurality of magnets positioned to bias the oscillation member to the closed position;
wherein the oscillation member is moveable from the closed position in response to a threshold pressure applied to the oscillation member.

Abstract
An oscillating positive expiratory pressure apparatus having a housing defining a chamber, a chamber inlet, a chamber outlet, a deformable restrictor member positioned in an exhalation flow path between the chamber inlet and the chamber outlet, and an oscillation member disposed within the chamber. The deformable restrictor member and the oscillation member are moveable between an engaged position, where the oscillation member is in contact with the deformable restrictor member and an disengaged position, where the oscillation member is not in contact with the deformable restrictor member. The deformable restrictor member and the oscillation member move from the engaged position to the disengaged position in response to a first exhalation pressure at the chamber inlet, and move from the disengaged position to an engaged position in response to a second exhalation pressure at the chamber inlet.

12. A respiratory treatment device comprising:
-
an inlet configured to receive exhaled air into the device; an outlet configured to permit exhaled air to exit the device; an oscillation member reciprocally moveable along a glide surface between a closed position, where the flow of exhaled air between the inlet and the outlet is restricted, and an open position where the flow of exhaled air between the inlet and the outlet is less restricted; a first magnet positioned on the oscillation member; and
,a second magnet positioned relative to the first magnet; wherein a magnetic force of the first magnet and the second magnet biases the oscillation member to the closed position. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of performing respiratory treatment, the method comprising:
-
passing a flow of exhaled air between an inlet and an outlet of a respiratory treatment device; biasing an oscillation member using a plurality of magnets to a closed position, where the flow of air between the inlet and the outlet is restricted, wherein a first magnet of the plurality of magnets is positioned on the oscillation member, and a second magnet of the plurality of magnets is positioned relative to the first magnet; and
,moving reciprocally the oscillation member from the closed position to an open position, where the flow of air between the inlet and the outlet is less restricted, when a force from the flow of exhaled air applied to the oscillation member exceeds a magnetic force of the plurality of magnets. - View Dependent Claims (20)
