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.

Abstract: A respiratory treatment device having an inlet configured to receive exhaled air into the device and an outlet configured to permit exhaled air to exit the device. A blocking member is moveable between a closed position where the flow of air through the device is restricted, and an open position where the flow of air through the device is less restricted. A biasing member is configured to bias the blocking member toward the closed position, wherein a level of bias decreases as the blocking member moves from the closed position to the open position.

Abstract: Ventilator circuit aerosol delivery systems used to administer medication to a patient are disclosed. In one implementation, a metered dose inhaler (“MDI”) ventilator assembly may include a housing that defines an interior space, an inhalation port that defines an inhalation passageway in communication with the interior space, an exhalation port that defines an exhalation passageway in communication with the interior space, a patient port that defines a patient passageway in communication with the interior space, and a MDI receptacle positioned on the housing and in communication with the interior space. The MDI receptacle is operative to receive a MDI container and dispense an aerosolized medication within the MDI container into the interior space so that during inhalation, an inhalation flow including the aerosolized medication may flow through the inhalation port, the interior space, and the patient port.

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.
