Oscillating positive expiratory pressure device
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.
1. 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, the channel comprising a truncated cone within the channel, wherein the truncated cone is defined by a base and a plane at an oblique angle relative to the base; and,
an air flow regulator moveable with respect to the channel in response to a flow of air along the flow path 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.
2. The respiratory treatment device of claim 1 , wherein an orientation of the channel relative to the housing is selectively adjustable by a user.
3. The respiratory treatment device of claim 1 , wherein an orientation of the channel relative to the air flow regulator is selectively adjustable by a user.
4. The respiratory treatment device of claim 1 , wherein the channel is rotatable about a central axis of the channel.
5. The respiratory treatment device of claim 1 , wherein the air flow regulator comprises a spherical shape.
6. The respiratory treatment device of claim 1 , wherein a weight of the air flow regulator offers a resistance to the flow of air through the channel.
7. The respiratory treatment device of claim 1 , wherein the air flow regulator is configured to repeatedly move between the first position and the second position in response to the flow of air along the flow path.
8. 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, the channel comprising a truncated cone within the channel, wherein the truncated cone is defined by a base and a central axis at an oblique angle relative to the base; and,
an air flow regulator moveable with respect to the channel in response to a flow of air along the flow path 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.
9. The respiratory treatment device of claim 8 , wherein an orientation of the channel relative to the housing is selectively adjustable by a user.
10. The respiratory treatment device of claim 8 , wherein an orientation of the channel relative to the air flow regulator is selectively adjustable by a user.
11. The respiratory treatment device of claim 8 , wherein the channel is rotatable about a central axis of the channel.
12. The respiratory treatment device of claim 8 , wherein the air flow regulator comprises a spherical shape.
13. The respiratory treatment device of claim 8 , wherein a weight of the air flow regulator offers a resistance to the flow of air through the channel.
14. The respiratory treatment device of claim 8 , wherein the air flow regulator is configured to repeatedly move between the first position and the second position in response to the flow of air along the flow path.
15. A method of performing respiratory therapy, the method comprising:
rotating an orientation of a channel comprising a truncated cone within the channel 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; and,
moving an air flow regulator with respect to the channel in response to the flow of air 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;
wherein the truncated cone is defined by a base and a plane at an oblique angle relative to the base.
16. The method of claim 15 , wherein selective adjustment of the orientation of the channel relative to the housing adjusts the resistance to the flow of air through the channel.
17. The respiratory treatment device of claim 1 , wherein the truncated cone is further defined by a central axis at a right angle relative to the base.
18. The respiratory treatment device of claim 1 , wherein the truncated cone is further defined by a central axis at an oblique angle relative to the base.
