Abstract: Method and apparatus for drying or purging droplets or films of liquid from the interior surfaces of hollow articles having an access passageway leading to a chamber, such as air rebreathing or resuscitator bags used in medical procedures that includes supporting the bag so as to dispose the access passageway lowermost and generating and directing a gaseous stream, preferably pressurized air, up through a portion of the passageway and releasing same for expansion into the chamber by means of an upstanding tubular formation terminating in a nozzle in the upper region thereof and withdrawing the expanded airstream downwardly through the remaining portion of the access passageway, whereby adhering liquid is impelled to coalesce to descend under gravity as well as taken up by entrainment and evaporation into the downwardly discharging airstream.
