ABSTRACT:
A device for independently controlling the temperature and/or relative humidity in the gas utilized in connection with a life support system formed by a chamber bounded by a bottom wall, side walls, and a top wall, one of the walls of the chamber provided with a gas inlet and a gas outlet, gas spider means associated with the gas inlet and providing gas passageways for segregating portions of the gas introduced into the device through the gas inlet, gas proportioning valve means positioned in association with the gas spider means and in line with the gas inlet to permit independent variable proportioning of the gases to at least two downline gas passageways, at least a first gas passageway traversing the gas spider means and terminating at the gas outlet and a second gas passageway traversing the gas spider means and in fluid communication with the chamber, the gas outlet being in fluid communication with the chamber and with the first passageway in the gas spider means, the chamber being adapted to hold a quantity of a fluid for humidifying the gas traversing therethrough, such that gas introduced into the system through the gas inlet may be variably proportioned to direct a portion of the gas through the gas spider means to the gas outlet, that gas being dry in nature, and another portion of the gas directed to a second passageway for introduction into the chamber to humidify the same and exiting the humidified gas into a passageway to admix with the first gas portion thereby forming a gas mixture having a controlled relative humidity. It is further contemplated to incorporate heat means such that gases may similarly be heated as well as humidified to achieve a gas admixture readily adjustable with respect to temperature and relative humidity.
