ABSTRACT:
A metered dosage inhaler device having a first member for receiving and dispensing inhalation medication which is hollow, and has an aerosol medication container insertion end and having a nozzle end for spraying medication into a mouth of a user, wherein the nozzle end has a defined length and has an orifice with a defined cross-sectional area outlet surfaces, inner surfaces and a defined outer perimeter at its termination. There is a second member, the second member which is a spacer fitted on the nozzle and adapted to move outwardly and inwardly relatively to the nozzle, the spacer being hollow and being located about either outer surfaces or within the inner surfaces of the nozzle, the spacer having a total length about equal to or less than the nozzle so as to preserve significant compactness when the spacer is moved inwardly relative to the nozzle. The spacer includes a plurality of movable segments such as telescopic ring segments. The first member has a tube with a reciprocal sleeve for holding a medication container and cooperates to permit full insertion of the segments into the first member.
