805,133. Treatment chambers. HIGGS, G. W. Dec. 5, 1956 [Dec. 5, 1955], No. 34825/55. Class 81 (2). A treatment chamber includes a heating and humidifying unit comprising a water tank 44, a heater 42 externally of the water tank, a valvecontrolled outlet 46 from the top of the tank and an air inlet passage 45 extending from the bottom of the tank to a point above the water level in the tank. A sheet-metal or thermoplastic body 10 containing the heating and humidifying unit is supported by a trolley 11 and has a shaft 24 which supports a tray 28 for the patient. The body 10 is covered by a canopy 12 made of toughened glass or thermoplastic material, the canopy 12 having a sloping roof with a hinged movable part 15 and hand openings 17 controlled by flexible sleeves 18. The inclination of the tray 28 is adjustable, one end of a tray-supporting frame 27 being mounted on links 34, 35 threaded on a shaft 29 which is rotatable by a handle 67. Air entering the body 10 through a gauze filter 54 in a tubular opening 53 is heated and humidified, by passing upwardly through tubes 45 into the water tank 44, and enters the treatment chamber through the outlet 46 controlled by a butterfly valve 47. A thermostatically-controlled heater 42 is located in a chamber 41 adjacent the water tank. Heated air from the chamber 41 flows via duct to an opening 59 and is directed against the canopy wall to prevent misting. The canopy 12 has air openings 19, 20. Oxygen may be introduced into the treatment chamber through a connection 66. An independent battery-energized circuit including a thermostatic device is completed to light a lamp 47 if the temperature within the treatment chamber falls below a predetermined minimum. A humidity meter 23 and a thermometer are located on the canopy 12. According to the Provisional Specification, the heater is located beneath the water tank which has a domed top.
