Abstract

415,048. Vaporizing anaesthetics. HAERTEL KOM.-GES., G., 24, Albrechtstrasse, Berlin. Feb. 10, 1933, No. 4119. Convention date, Feb. 10, 1932. [Class 81 (i).] Apparatus for preparing anµsthetics comprises a chamber 1 into which a liquid anaesthetic is introduced in drop form and vaporized, the vapour mixed with air or other gas being caused to flow in a devious path whilst being heated by means of a thermophore 7, preferably filled with sodium acetate, well above its boiling point. The liquid flows over a distributer 4 on to porous material 5 such as pumice and mixes with air supplied at 2, leaving through a pipe 6. The pipe has an orifice which can be brought into register with an orifice in a sleeve 8 movable on the pipe, so that atmospheric air may enter. One or more partitions 9 may be provided. When ether is employed the vapour is heated to about 55‹ C. The Specification as open to inspection under Sect. 91 comprises the use of electric, gas, or other form of heating for the vaporizer. This subject-matter does not appear in the Specification as accepted.
