  • Publication number: 20200390988
    Abstract: A spacer device for an inhaler. The device may include a hollow tube. The device may also include a piston member configured to be inserted into the hollow tube such that a space between a first end of the hollow tube and the piston member may define a chamber for holding a mist released from the inhaler. The piston may be slidable along the hollow tube towards the first end of the hollow tube as the mist is aspirated from the chamber. The hollow tube and the piston member may cooperate to provide a visual indication of the progress of the aspiration of the mist from the chamber.
