Abstract

An oscillating positive expiratory pressure device comprising a housing enclosing at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, and a chamber outlet configured to permit exhaled air to exit the at least one chamber. A channel is positioned in an exhalation flow path between the chamber inlet and the chamber outlet, with the channel being moveably connected to a chamber of the at least one chamber. An air flow regulator is moveable with respect to the channel between a first position, where the flow of air through the channel is restricted and a second position, where the flow of air through the channel is less restricted, the air flow regulator being configured to repeatedly move between the first position and the second position in response to a flow of exhaled air.

First claim

1 .- 20 . (canceled)

21 . A respiratory treatment device comprising:
a housing enclosing a chamber; a chamber inlet configured to receive air into the chamber; a chamber outlet configured to permit air to exit the chamber; a channel positioned in a flow path between the chamber inlet and the chamber outlet, wherein the channel comprises a cone cut by an oblique plane; and, an air flow regulator moveable with respect to the channel between a first position where the flow of air through the channel is restricted, and a second position where the flow of air through the channel is less restricted.

22 . The respiratory treatment device of claim 21 , wherein an orientation of the channel relative to the housing is selectively adjustable by a user.

23 . The respiratory treatment device of claim 21 , wherein an orientation of the channel relative to the air flow regulator is selectively adjustable by a user.

24 . The respiratory treatment device of claim 21 , wherein the channel is rotatable about an axis of the cone.

25 . The respiratory treatment device of claim 21 , wherein the air flow regulator comprises a spherical shape.

26 . The respiratory treatment device of claim 21 , wherein a weight of the air flow regulator offers a resistance to the flow of air through the channel.

27 . The respiratory treatment device of claim 21 , wherein the air flow regulator is configured to repeatedly move between the first position and the second position in response to a flow of air along the flow path.

28 . A respiratory treatment device comprising:
a housing enclosing a chamber; a chamber inlet configured to receive air into the chamber; a chamber outlet configured to permit air to exit the chamber; a channel positioned in a flow path between the chamber inlet and the chamber outlet, wherein the channel comprises an oblique truncated cone; and, an air flow regulator moveable with respect to the channel between a first position where the flow of air through the channel is restricted, and a second position where the flow of air through the channel is less restricted.

29 . The respiratory treatment device of claim 28 , wherein an orientation of the channel relative to the housing is selectively adjustable by a user.

30 . The respiratory treatment device of claim 28 , wherein an orientation of the channel relative to the air flow regulator is selectively adjustable by a user.

31 . The respiratory treatment device of claim 28 , wherein the channel is rotatable about an axis of the cone.

32 . The respiratory treatment device of claim 28 , wherein the air flow regulator comprises a spherical shape.

33 . The respiratory treatment device of claim 28 , wherein a weight of the air flow regulator offers a resistance to the flow of air through the channel.

34 . The respiratory treatment device of claim 28 , wherein the air flow regulator is configured to repeatedly move between the first position and the second position in response to a flow of air along the flow path.

35 . A method of performing respiratory therapy, the method comprising:
rotating an orientation of a channel, comprising a cone cut by an oblique plane, relative to a housing of a respiratory treatment device having an inlet configured to receive air into the housing and an outlet configured to permit air to exit the housing; receiving a flow of air into the housing; directing the flow of air through the channel; moving an air flow regulator with respect to the channel repeatedly between a first position where the flow of air through the channel is restricted, and a second position where the flow of air through the channel is less restricted.

36 . The method of claim 35 , wherein the orientation of the channel relative to the housing is selectively adjustable independent of an orientation of the housing.

37 . The method of claim 35 , wherein the orientation of the channel relative to the air flow regulator is selectively adjustable independent of an orientation of the housing.

38 . The method of claim 35 , wherein the air flow regulator moves repeatedly between the first position and the second position in response to the flow of air through the channel.

39 . The method of claim 35 , wherein a weight of the air flow regulator offers a resistance to the flow of air through the channel.

40 . The method of claim 39 , wherein selective adjustment of the orientation of the channel relative to the housing adjusts the resistance to the flow of air through the channel.
