  • Publication number: 20250281714
    Abstract: A respiratory treatment device comprising at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, at least one chamber outlet configured to permit exhaled air to exit the at least one chamber, and an exhalation flow path defined between the chamber inlet and the at least one chamber outlet. A restrictor member positioned in the exhalation flow path is moveable between a closed position, where a flow of exhaled air along the exhalation flow path is restricted, and an open position, where the flow of exhaled air along the exhalation flow path is less restricted. A vane in fluid communication with the exhalation 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 exhaled air along the exhalation flow path.

  • Publication number: 20250135132
    Abstract: A respiratory treatment device includes a housing enclosing a chamber, a chamber inlet configured to receive a flow of air into the chamber, a first chamber outlet configured to permit the flow of air to exit the chamber, and a second chamber outlet configured to permit the flow of air to exit the chamber. A vane mounted within the chamber is configured to rotate between a first position where the flow of air is directed to exit the chamber through the first chamber outlet, and a second position where the flow of air is directed to exit the chamber through the second chamber outlet. A blocking member disposed on the vane is moveable relative to the chamber inlet between a closed position where the flow of air through the chamber inlet is restricted, and an open position where the flow of air through the chamber inlet is less restricted.

  • Publication number: 20200306468
    Abstract: An oscillating positive respiratory pressure apparatus and a method of performing oscillating positive respiratory pressure therapy. The apparatus includes a housing having an interior chamber, a chamber inlet, a chamber outlet, an exhalation flow path defined between the inlet and the outlet, and a restrictor member rotatably mounted within the interior chamber. The restrictor member has an axis of rotation that is substantially perpendicular to the flow path at the inlet, and includes at least one blocking segment. Rotation of the restrictor member moves the at least one blocking segment between an open position and a closed position. Respiratory pressure at the chamber inlet oscillates between a minimum when the at least one blocking segment is in the open position and a maximum when the at least one blocking segment is in the closed position. By exhaling into the apparatus, oscillating positive expiratory pressure therapy is administered.
