A restrictor member positioned in the flow path is moveable between a closed position, where a flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted. A vane in fluid communication with the 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 air along the flow path. ## Claims ### Claim 1 A respiratory treatment device comprising: a housing enclosing at least one chamber; a chamber inlet configured to receive air into the at least one chamber; at least one chamber outlet configured to permit air to exit the at least one chamber; a flow path defined between the chamber inlet and the at least one chamber outlet; an orifice positioned in the at least one chamber along the flow path such that the flow path passes through the orifice, and, a vane positioned adjacent the orifice, the vane being configured to rotate in response to the flow of air through the orifice; wherein a peripheral portion of the vane is angled relative to a central portion of the vane to direct substantially all the flow of air through the orifice to a side of the vane when the central portion of the vane is substantially aligned with the orifice. ### Claim 2 (depends on 1) The respiratory treatment device of claim 1, wherein the central portion of the vane is substantially planar. ### Claim 3 (depends on 1) The respiratory treatment device of claim 1, further comprising a restrictor member operatively connected to the vane, the restrictor member being configured to rotate between a closed position, where the flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted. ### Claim 4 (depends on 3) The respiratory treatment device of claim 3, wherein the restrictor member and the vane are operatively connected by a shaft. ### Claim 5 (depends on 4) The respiratory treatment device of claim 4, wherein the restrictor member has a center of mass offset from an axis of rotation of the shaft. ### Claim 6 (depends on 5) The respiratory treatment device of claim 5, wherein a force of gravity biases the restrictor member and the vane toward a position where the central portion of the vane is not aligned with the orifice. ### Claim 7 A respiratory treatment device comprising: a housing enclosing at least one chamber; a chamber inlet configured to receive air into the at least one chamber; at least one chamber outlet configured to permit air to exit the at least one chamber; a flow path defined between the chamber inlet and the at least one chamber outlet; an orifice positioned in the at least one chamber along the flow path such that the flow path passes through the orifice, and, a vane positioned adjacent the orifice, the vane being configured to rotate in response to the flow of air through the orifice; wherein a peripheral portion of the vane is configured to flex relative to a central portion of the vane in response to the flow of air through the orifice. ### Claim 8 (depends on 7) The respiratory treatment device of claim 7, wherein the vane is substantially planar. ### Claim 9 (depends on 7) The respiratory treatment device of claim 7, wherein a flexibility of the peripheral portion of the vane is greater than a flexibility of the central portion of the vane. ### Claim 10 (depends on 7) The respiratory treatment device of claim 7, wherein the peripheral portion of the vane and the central portion of the vane are separated by at least one hinge point. ### Claim 11 (depends on 10) The respiratory treatment device of claim 10, wherein the at least one hinge point comprises a channel. ### Claim 12 (depends on 7) The respiratory treatment device of claim 7, further comprising a restrictor member operatively connected to the vane, the restrictor member being configured to rotate between a closed position, where the flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted. ### Claim 13 A respiratory treatment device comprising: a housing enclosing at least one chamber; a chamber inlet configured to receive air into the at least one chamber; at least one chamber outlet configured to permit air to exit the at least one chamber; a flow path defined between the chamber inlet and the at least one chamber outlet; an orifice positioned in the at least one chamber along the flow path such that the flow path passes through the orifice, and, a vane positioned adjacent the orifice, the vane being configured to rotate in response to the flow of air through the orifice; wherein the vane is biased toward a position where a central portion of the vane is not aligned with the orifice. ### Claim 14 (depends on 13) The respiratory treatment device of claim 13, wherein the vane is substantially planar. ### Claim 15 (depends on 13) The respiratory treatment device of claim 13, wherein the vane is biased by an elastic band. ### Claim 16 (depends on 15) The respiratory tournament device of claim 15, where an end of the elastic band is attached to a side of the vane opposite the side of the vane adjacent the orifice. ### Claim 17 (depends on 13) The respiratory treatment device of claim 13, further comprising a restrictor member operatively connected to the vane, the restrictor member being configured to rotate between a closed position, where the flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted. ### Claim 18 (depends on 17) The respiratory treatment device of claim 17, wherein the restrictor member and the vane are operatively connected by a shaft. ### Claim 19 (depends on 18) The respiratory treatment device of claim 18, wherein the restrictor member has a center of mass offset from an axis of rotation of the shaft. ### Claim 20 (depends on 19) The respiratory treatment device of claim 19, wherein a force of gravity biases the restrictor member and the vane toward the position where the central portion of the vane is not aligned with the orifice.
