Abstract

An assistive device for a metered dose inhaler decreases the force required to operate the inhaler. The assistive device has a body with a passage for receiving a replaceable conventional metered dose inhaler assembly that has a canister and a transverse mouthpiece with an axis of the canister aligning approximately with that of the passage. At least two symmetrically arranged levers extend in a direction away from the body and parallel to an axis thereof. A proximal end of each lever is attached to the body such that the free opposite ends of the levers may be moved towards and away from each other. An inwardly directed cam surface on each of the levers engages a closed end of a canister in use to move the canister longitudinally to cause a dose of medicament to be dispensed from the canister. An optional dose counter may form part of the device.
