Abstract

Abstract An inhalation device of the type adapted to receive and locate an aerosol container designed to administer a multiplicity of metered doses, said aerosol container having a composition under pressure therein and having metering valve means including a valve stem and associated metering means, the valve stem having an axial discharge tube extending therethrough for discharge of a metered dose upon actuation of said metering valve means by depression of said valve stem, said inhalation device comprising a body having a skirt adapted to receive and locate said aerosol container in a first end thereof and a head-piece connected to a second end of said skirt, a mouth-piece extending from said head-piece and in communication therewith, and an audible signal generating means, said head-piece having actuating means for said metering valve means and a discharge passageway leading to a discharge orifice directed towards said mouth-piece, said actuating means being engageable with the valve stem upon location of the container within the skirt and operable to actuate the metering valve means whereby a metered dose is discharged through the valve stem discharge tube and the discharge passageway and discharge orifice into the mouth-piece, wherein said audible signal generating means is located in said air-passageway within the body upstream of said discharge orifice and surrounds the actuating means for the metering valve means, and is actuatable upon inhalation through said mouth-piece when said inhalation device is in engagement with said container.

Claim 2
Dependent Claim 282 words
An inhalation device of the type adapted to receive and locate an aerosol container designed to administer a multiplicity of metered doses, said aerosol container having a composition under pressure therein and having metering valve means including a valve stem and associated metering means, the valve stem having an axial discharge tube extending therethrough for discharge of a metered dose upon actuation of said metering valve means by depression of said valve stem, said inhalation device comprising a body having a skirt adapted to receive and locate said aerosol container in a first end thereof and a head-piece connected to a second end of said skirt, a mouth-piece extending from said head-piece and in communication therewith, and an audible signal generating means, said head-piece having actuating means for said metering valve means and a discharge passageway leading to a discharge orifice directed towards said mouth-piece, said actuating means being engageable with the valve stem upon locating of the container within the skirt and operable to actuate the metering valve means whereby a metered dose is discharged through the valve stem discharge tube and the discharge passageway and discharge orifice into the mouth-piece, an air-passageway extending through at least part of said body from a location at least upstream of said actuating means to said mouth-piece and providing a path for air to flow from the ambient into the mouth-piece upon inhalation through the mouth piece, wherein said audible signal generating means is located in said air-passageway within the body upstream of said discharge orifice and surrounds the actuating means for the metering valve means, and is actuatable upon inhalation through said mouth-piece when said inhalation device is in engagement with said container.
Claim 3
Dependent Claim 64 words
A device as claimed in claim 1 wherein said actuating means for said metering valve means comprises a valve stem boss adapted to receive the valve stem within a discharge passageway therein, said discharge passageway having means for limiting entry therein of said valve stem and a discharge orifice communicating with said discharge passageway and adapted to discharge said metered dose through said mouth-piece.
Claim 4
Dependent Claim 30 words
A device as claimed in claim 2 wherein said means generating an audible signal is located upstream of said boss between the space reserved for the container and said boss.
Claim 5
Dependent Claim 29 words
A device as claimed in claim 3 wherein said means generating an audible signal abuts against the valve stem boss, preferably against the end surface thereof facing the container.
Claim 6
Dependent Claim 32 words
A device as claimed in claim 4 wherein said means generating an audible signal is apertured to receive the end surface thereof and has a rim to limit penetration of said boss.
Claim 7
Dependent Claim 31 words
A device as claimed in claim 1 wherein said means generating an audible signal is responsive to an air-flow in one direction only past said means and out through said mouth-piece.
Claim 8
Dependent Claim 24 words
A device as claimed in claim 1 wherein the soundgenerating part of said means generating an audible signal is a vibratory reed or tongue.
Claim 9
Dependent Claim 25 words
A device as claimed in claim 7 wherein said means generating an audible signal is a thin membrane having the vibratory reed or tongue therein.
