Abstract
A first and second housing joined together and rotatable with respect to each other, each housing having a conduit integral with an exterior wall, the conduits each having passageways leading to an internal portion of the respective housings. An internal edge of each housing mounts a heat-moisture exchange material having a transverse opening axially aligned with the passageway of the closest conduit. The passageway in the respective conduits are offset permitting passage of air to and from the patient through the heat-moisture material. The housings are rotated with respect to each other to axially align the passageways in the two conduits to permit passage of aerosol medicine through the exchanger without passing through the heat-moisture material.
