Abstract
A dispenserhas a source of medicamentwith a canand a metered dose valve. The outlet stemof the valve is fitted to a junction blockin a bodyof the dispenser to which a breath actuated dose release mechanismis connected for release of the medicament through a nozzle. The can has an acoustic transducerattached to its side wall, in intimate acoustic contact. An electronic package, comprising a detection circuit and a driver for a LCD displayare also mounted on the can wall, the transducer being connected to the circuit. The detection circuit is arranged to decrement a count shown on the LCD by one for every detection of noise of dispensing/metering of a dose from the can. The detection circuit is programmed to compare the spectrum of the noise with a known dose-dispensing spectrum and to decrement the counter according to the comparison.
