Abstract

A dose indicating device constructed for use with an inhalator is disclosed. The inhalator contains multiple doses of a medicament and has an operational portion that includes a dosing unit defining an inhalation channel, and a maneuvering element. The maneuvering element loads a dose of the medicament to the dosing unit and provides the dose in a position in the inhalation channel for inhalation. The dose indicating device includes: a body constructed to be mounted on the maneuvering element of the inhalator; a first element constructed to be mounted on and around an outer wall surface of the maneuvering element; a second element rotatably mounted on and around the outer surface of the first element for rotation relative to the first element; corresponding portions provided on the first and second elements constructed to engage when the inhalator is activated for inhalation in a manner to limit relative movement between the first and second elements; and an indicator constructed to detect movement of the maneuvering element and indicate to a user of the inhalator that a dose has been fed to the inhalation channel when the inhalator is activated for inhalation.
