An aerosol medication delivery system includes a holding chamber having an output end with a plurality of tabs extending from an exterior. A patient interface includes a housing having an annular attachment collar configured with a plurality of openings receiving the plurality of tabs. The housing has a plurality of engagement members formed on an interior of the housing and an interior wall defining a sealing surface. A retaining ring is engaged by the engagement members and is coupled to an interior of the housing. A one-way inhalation valve includes a non-moveable annular valve seat engaged by the retaining ring and the sealing surface of the interior wall. A one-way exhalation valve is formed separately from the one-way inhalation valve, and is coupled to the patient interface.

Medication delivery apparatus and system and methods for the use and assembly thereof

A delivery system includes a holding chamber with first, second and third openings, and independently moveable first, second and third flow control members. A delivery system includes a holding chamber and a flow control member including a flap pivotable from an at rest position in a direction toward an outlet of a user interface and away from an output end of the holding chamber in response to a pressure being applied thereto.

Visual indicator for an aerosol medication delivery apparatus and system

A flow indicating system that includes a conduit that contains a substance, wherein the conduit defines a path along which the substance primarily flows and a viewing port attached to the conduit and the viewing port prevents substantially non-ambient atmosphere gases and substances from escaping therefrom and allows visualization of an internal space defined by the viewing port. A flow indicator that is positioned within the conduit so as to be viewed via the viewing port and is positioned so as to not to substantially interfere with a flow of the substance along the path.
