摘要：
A spacer device for an inhaler, comprising a hollow tube and 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 defines a chamber for holding a mist released from the inhaler. The piston member is 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 cooperate to provide a visual indication of the progress of the aspiration of the mist from the chamber. The hollow tube may comprise at least a transparent or translucent portion. The piston member may contain a skirting around its perimeter.
