ABSTRACT:
A therapeutic inhalation device for receiving a dose of oronasal medication from a pressurized aerosol source and for delivering the same in dispersed and nonpressurized form to a breathing passage of a patient is comprised of top and bottom members and a collapsible sleeve attached at its opposite ends to the top and bottom members and defining therewith a spacer or breathing chamber that is extendable and contractible. The bottom member is cup-shaped and of a size to receive the sleeve and top member when the sleeve is collapsed and the top member is inserted into the bottom member, thereby to provide a device which, when not in use, is small and compact and conveniently stored and transported. The top member is provided with a guide member for positioning a medication containing aerosol canister for dispensing of its contents into the spacer chamber and an inhalation member communicating with the chamber for delivery of the medication to the patient in the form of a non-pressurized dilute dispersion. The guide and inhalation members are movable to retracted storage positions within the top member for convenience of storage and transportation.
