Abstract: An infant inhaler in which the aerosol medication is communicated into a flexible bag. Using a mask, during inhalation, the medicated air within the flexible bag is drawn into the infant's lungs; exhalation from the infant is exhausted into the atmosphere. By watching the deflation of the flexible bag, the care-giver is appraised of the progress of the medication's inhalation. The entire assembly is held with one hand allowing the infant to be cradled in the other arm. Refilling of the flexible bag with ambient air is accomplished by inverting the apparatus which causes the valves therein to open and allow ambient air into the flexible bag. Refilling the flexible bag with medication is done using a single hand by pressing the aerosol bottle against the apparatus.

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.
