A medicament dispensing device comprises a housing (400) for receiving a medicament delivery system (25), e.g., an aerosol can, actuable to deliver discrete doses of medicament. An actuation device has a spring loaded sleeve (420) for engaging the aerosol can at its base end, when the actuation device is released on inhalation at a mouthpiece (405) of the housing. A dose counter comprises a rotary dose indicating ring (101) surrounding the sleeve (420) to be indexed incrementally by a resilient indexing member provided on the sleeve, on each actuation of the aerosol can (25) to discharge a dose of medicament. |
