ABSTRACT:
A spacer for use with a powdered medicament inhaler. The spacer comprises a slender curved body, which defines a chamber, an inlet communicating with the chamber and an outlet communicating with the chamber. The inlet and outlet are adapted to provide a rotational flow path in use for an airstream passing from the inlet through the chamber to the outlet. This selectively extracts particles of powdered medicament entrained in the airstream.
