A breathing circuit apparatus used with a nebulizer device that generates an aerosol is adapted for use by a user for inhaling the aerosol through the user's nose and/or mouth and thereafter exhaling exhalation gas through the breathing circuit apparatus. The breathing circuit apparatus includes a container, an inlet valve, an outlet valve and a user connection port. The container defines an interior chamber therein and is coupled to the nebulizer device. The inlet valve is connected to the container and includes an air inlet port for one-way air flow of ambient air into the interior chamber. The inlet valve moves between a closed condition to prevent the ambient air from entering into the interior chamber and an opened condition to permit the ambient air to enter into the interior chamber. The outlet valve is connected to the container and includes a gas exhalation port for one-way gas flow of the exhalation gas. The outlet valve moves between a closed state to prevent exhalation gas from exiting the interior chamber and an opened state to permit exhalation gas to exit from the interior chamber. The user connection port is in fluid communication with the interior chamber and the user's nose and/or mouth when the user inhales and exhales. As the user inhales the aerosol from the interior chamber, the inlet valve is opened and the outlet valve is closed. As the user exhales, the inlet valve is closed and the outlet valve is opened to allow the exhalation gas to exit the interior chamber and discharge into the exterior ambient air. |
