Abstract:
An inhalation device comprising:a collapsible storage container having a container interior and a container opening; a patient connection; a main conduit fluidly coupling the container interior to the patient connection; an aerosol entry port at a first position along the main conduit; a generally L-shaped flow diverter positioned within the main conduit at the first position, the flow diverter dividing a portion of the main conduit into an aerosol channel and an exit channel, the aerosol channel having an at least substantially closed end towards the patient connection and an open end towards the container interior, the aerosol channel shaped so that aerosol flow through the entry port is directed along the aerosol channel in a laminar flow regime into the container interior; and a flow-resistant ambient port opening into the main conduit.
