A medication delivery apparatus comprising:
- an antistatic holding chamber that has an input end and an output end spaced apart along a longitudinal axis;
- a patient interface component connected to said output end and comprising an interior surface defining a flow passage;
- and
- a valve disposed adjacent said output end, said valve comprising a flexible material and moveable between an open position and a closed position, wherein said valve has a central opening when in said open position, said central opening having a flow path along said longitudinal axis, so as to facilitate a flow from the antistatic holding chamber to a patient,
- wherein the valve comprises a first valve element and a second valve element wherein the second valve element is shaped like a hinged flap, and the valve is configured to block a flow of exhaled air upstream in the direction of the antistatic holding chamber, and the valve configured to permit the exhaled air to be exhausted through a sidewall of a housing.
