Abstract

631,577. Anµsthetic apparatus. TALLEY, H. A. E. Dec. 22, 1947, Nos. 33783 and 33784. [Class 81(ii)] Anaesthetic apparatus comprises a rebreathing circuit for the patient, uni-directional valve means 12, 14, to prevent reverse flow of gases round the circuit, soda-lime absorption means 18 and a rebreathing bag 22 which can both be brought into the circuit or by-passed by a single rotary sleeve valve 16, together with further valve means 9 whereby fresh gases may be fed into the circuit with or without passing through ether in a bottle 8 and whereby the circuit may include passing over ether. The fresh gases are applied to the circuit through flow gauges 3, oxygen and nitrous oxide bye-pass control valves 5, 6, being provided. The soda-lime cartridge 18 is replaceable and the inflation of the re-breathing bag 22 is controlled by an adjustable arm 42.
