An apparatus for aerosol medicament delivery, comprising:
- a holding chamber having an interior, a first end and a second end, the first end being adapted to accept a source of aerosol medicament, the interior having a surface reducing attraction between particles of the medicament and the interior of the holding chamber;
- an adapter member connected to the holding chamber;
- a delivery member connected to the adapter member;
- a valve disposed at least partially within the delivery member, the valve comprising a base and a non-planar first valve element, the first valve element defining a split, the split being configured to:
- open upon inhalation by a subject, permitting the delivery of aerosol from the holding chamber to the subject;
- and
- close upon exhalation by a subject, preventing exhaled air from entering the interior of the holding chamber.
