RADIOACTIVE AEROSOL INHALATION APPARATUS AND METHOD

摘要

A disposable aerosol inhalation device for use in producing properly sized radioactive tagged particles. A mouthpiece is attached to a wye connector containing a valving system for inhalation of the radioactive aerosol and exhalation to an entrapping filter. Conduits are respectively provided by flexible tubing to a nebulizer and to the filter. The optimum range of particle sizes is generated by producing an aerosol from the nebulizer having an internal baffle. For ease of handling and to minimize radiation exposures, an entry is provided to add radioactive solution directly into the baffled nebulizer. To further reduce radiation exposure, the baffled nebulizer and entrapping filter are housed in a leaded enclosure.
