1. A medication delivery system comprising:
- a chamber housing comprising an exit port;
a patient interface releasably coupled to the chamber housing and comprising a mouthpiece defining an inhalation conduit and defining an opening positioned above the inhalation conduit;
a flow control member comprising a flap having a free end and an anchor portion formed along an end of the flap opposite the free end, wherein the flow control member is slideable from a non-engaged position, wherein the anchor portion is disengaged from the mouthpiece, to an engaged position, wherein the anchor portion is engaged with the mouthpiece and wherein the flap covers the opening, wherein the patient interface and flow control member define a self-contained unit when the flow control member is in the engaged position, wherein the self-contained unit is moveable between a disengaged position such that the self-contained unit is decoupled from the chamber housing, to an engaged position such that the self-contained unit is coupled to the chamber housing.
