Abstract

636,854. Anµsthetic apparatus. MACDONALD, T. J. C. May 20, 1948, No. 13750. [Class 81 (ii)] An apparatus for administering anµsthetic vapour comprises a closed chamber 12, in the lower part of which the liquid anaesthetic 14 is contained, a skirt 18 depending from the lid to below the surface of the liquid, a central tube 19 extending from above the liquid surface to a venturi tube 21, and a one-way valve 27 in the outlet leading to the face mask. If desired, a cock or valve 26 of any desired type may be fitted in the central tube to control the ratio of anaesthetic to inhaled air.
