Abstract

331,050. Wellesley, G., and Coxeter & Son, Ltd. May 15, 1929. Inhalers.-In an apparatus for administering anµsthetics, air, nitrous oxide, or other gas from an air pump or cylinders of compressed gas, connected to pipes 9, 10, 11, is passed through a sight feed device and into a. cylindrical casing 8, from which it may be passed through or over anµsthetics such as chloroform or ether, contained in bottles 5, 6 to an outlet nozzle 8<a>. The sightfeed device is formed by the supply tubes 9, 10, 11 having a vertical series of discharge openings 18 below the surface of the water contained in the bottle 4. The gas may be passed through tubes 12, 13 and 5, 6, or through bye-passes 14, 15 by means of sleeve valves. The amount of anµsthetic taken up is controlled by means of bells 26, 28 adjustable by rods 23, 25. Tube 11, and, if desired, tubes 9, 10 also, are provided with byepass valves 20, Fig. 3, opening directly into the cylinder 8.
