Abstract

191,169. Hall, L. B. Oct. 8, 1921. Inhalers. - Apparatus for use in administering anaesthetics comprises one or more gas bottles D fitted with automatic pressure regulators E, and connected through fine adjustment valves F, G to perforated tubes B, C immersed in water or other liquid in a glass vessel A, so that the rate of flow of the gases may be observed. The gases pass to an ether vessel O fitted with a valve comprising an outer drum H, Figs. 1 and 3, within which an inner drum J is rotatably mounted. The drum J may be turned so that the gases pass directly through the transverse tube N to the patient, or so that the full volume of gas passes to one of a series of chambers K, L, M, thence through tubes of varying length projecting from the drum J into the ether bottle and then through the outlet P to the patient. The ether bottle O may be recharged from a stock bottle R by allowing gas under pressure to pass from a valve Q to the stock bottle, thus forcing the ether through the tube S to a filling aperture T on the drum J.
