ABSTRACT:
An apparatus for measuring the amount of medication in a sealed metered dose inhaler dispenser comprises a housing in which a mounting platform is located. An aperture in the housing allows the dispenser to be placed on the platform. Displacement of the platform is correlated with the weight of the dispenser and contents. The weight is displayed as an indication of the amount of medication in the dispenser from full to empty. The platform means may rest on a compression spring, the deflection of the spring being correlated with the applied weight. Tabs associated with the platform align with indicia on the exterior of the housing to indicate the degree of dispenser fill.
