ABSTRACT:
Aerosol inhalation apparatus for supplying an aerosol mist containing radioactive tagged particles and air to a person, includes a nebulizer for producing the aerosol mist; a filter having one end open to atmosphere; a first conduit connecting the opposite end of the filter and the nebulizer; a second conduit having one end fluidly connected to the first conduit; a mouthpiece connected to the opposite end of the second conduit; and a reusable container for containing the nebulizer, filter and first conduit; whereby, during inhalation, the aerosol mist travels to the second conduit from the nebulizer and the first conduit, and during exhale, exhaust air and aerosol mist travel to the filter from the second conduit through the first conduit such that the exhaust air is expelled to atmosphere and the aerosol mist becomes trapped. The nebulizer includes a housing for containing radioactive solution; an aerosol device in the housing for producing the aerosol mist, the aerosol device including a mixing chamber having a small outlet opening and being used to mix the radioactive tagged particles and air to form the aerosol mist, an oxygen supply tube for supplying oxygen to the chamber, a radioactive solution supply tube for supplying the radioactive solution from the housing to the chamber in response to the oxygen supply thereto, whereby the aerosol mist exits through the small outlet opening; and a diffuser positioned immediately above the small outlet opening for breaking up radioactive tagged particles of the aerosol mist into smaller particles.
