ABSTRACT:
A collapsible, articulated actuator for the aerosol delivery of a medicament comprised comprises an elliptical expansion chamber hingedly and slideably attached to an aerosol cannister-receiving portion in a manner which permits the cannister-receiving portion to be telescoped into the expansion chamber for storage. In use, the cannister-receiving portion is pulled out of the expansion chamber and rotated until it locks into position at an angle ranging between about 102.degree. and 110.degree. with the expansion chamber. The angle between the two portions of the actuator, the volume of the expansion chamber, and the degree of elliptical eccentricity of the expansion chamber are optimized for maximum delivery of an aerosolized medicament to the deep lungs of a patient.
