[Hygienic problems during sputum provocation by aerosol (author's transl)]. 1976

R Grünewald

An apparatus assembly is described providing hygienic conditions to obtain sputum after aerosol inhalation. It is composed of an ultrasonic nebulizer and a half-opened exhausting hood. The patient's head is placed under the hood which inhibits the delivery of expectorated germs into the environmental space. A continuous air flow in the direction of coughing is leading the sputum particles (droplet nuclei) towards a filter system. After decontamination the air may be let off outwards or back into the room.
