  • Patent number: 3962381
    Abstract: This invention relates to an apparatus for the humidification of a gas, and it comprises an outer container having an inner chamber and a top cover. Within the inner chamber is a helix-shaped gas bubble conveyer. Water is introduced into the container, which in turn, fills the chamber. Gas bubbles are introduced into the chamber, and as they traverse the helix pathway, they are saturated with the water. Means are provided for recirculating the water and maintaining it at any desired temperature.
