Abstract
An adjustable airflow diffuser for selectively diffusing a flow of treatment gas includes a first member adapted to be disposed in the flow and a second member movably coupled to the first member and also adapted to be disposed in the flow. The second member is selectively moveable from: (i) a first position with respect to the first member in which the first member and the second member form a first turbulating arrangement, and (ii) a second position with respect to the first member in which the first member and the second member form a second turbulating arrangement.
Claims15
An adjustable airflow diffuser for selectively diffusing a flow (F) of treatment gas being provided to a patient interface device from a pressure generating device, the diffuser comprising:
- a first member adapted to be disposed in the flow;
- and
- a second member movably coupled to the first member, the second member adapted to be disposed in the flow, wherein the second member is selectively moveable from (i) a first position with respect to the first member in which the first member and the second member form a first turbulating arrangement, and (ii) a second position with respect to the first member in which the first member and the second member form a second turbulating arrangement.
A delivery conduit for communicating a flow (F) of breathing gas from a pressure generating device to an interface device, the delivery conduit comprising:
- a first end adapted to receive the flow of breathing gas from the pressure generating device;
- a second end adapted to communicate the flow to the interface device;
- a first member positioned to be disposed in the flow between the first end and the second end;
- and
- a second member movably coupled to the first member, the second member positioned to be disposed in the flow between the first end and the second end, the second member being selectively moveable from (i) a first position with respect to the first member in which the first member and the second member form a first turbulating arrangement, and (ii) a second position with respect to the first member in which the first member and the second member form a second turbulating arrangement.
A method of diffusing a flow of breathing gas being provided to a patient interface device from a pressure generating device, the method comprising:
- providing a first member in the flow of breathing gas;
- providing a second member in the flow of breathing gas;
- and
- enhancing diffusion of the flow of breathing gas by adjusting the relative position of the first member and the second member from:
- (i) a first position in which the first member and the second member form a first turbulating arrangement, to (ii) a second position in which the first member and the second member form a second turbulating arrangement.
