ABSTRACT:
In order to render harmless the aerosol laden smoke stream which results from the operation of medical lasers in or on mammalian bodies, the stream is moved in a closed circuit maintained at negative pressure. The circuit includes a container of sterilizing fluid to retain and destroy the larger aerosol particles and downstream of that container a chamber having an oxygen enriched atmosphere which is heated to a temperature sufficient to incinerate the remaining aerosol particles which are too small to filter. The thus purified stream is then cooled and released to ambient.
