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.

Abstract: A valved holding chamber has an input end and an output end, which includes an inhalation valve and a user interface. The inhalation valve defines a first inhalation flow path between the input end and the user interface. A flow channel includes an inlet in flow communication with the holding chamber and an outlet in flow communication with the user interface downstream of the inhalation valve, wherein the flow channel bypasses the inhalation valve and defines a second inhalation flow path between the input end and the user interface. A flow indicator is positioned in the flow channel. A second flow channel, with a second flow indicator dispose therein, may define a third inhalation flow path between the input end and the user interface separate from the first and second inhalation flow paths. The inhalation valve, first flow indicator and second flow indicator may have different flow resistances.

Abstract: A system and method for use in matching a source to a dynamic impedance electrical load is described. The system may include a processor that controls a signal generator to sweep across a frequency spectrum to locate a resonant frequency of the dynamic impedance load. The determination of resonant frequency may be made based on sensing the power consumption of the amplifier supplying the load and locating the frequency at which the power consumption is minimized. Periodically tracking and adjustment of the frequency to maintain a minimum power consumption may be automatically performed. The load may be a SAW atomizer.
