ABSTRACT:
A humidifier for air or gas flow to the lungs heats the flow and saturates it with water vapor. Heated water injected into a humidifying passage flows down multiple paths in the gas stream. Heating of the water is shown on a localized basis at sterilizing temperature while over-all temperature is kept lower using a heater combined with the pump of the injection line. All surfaces of the humidifier are shown exposed to the water; the gas outlet connection is shown communicating with a space between the water paths and the reservoir, and directed toward the reservoir; and the humidifying passage is shown as a tubular column holding a mass of tangled inert filaments.
