Abstract

704,167. Anaesthetic apparatus. HAMMERMANN, H. March 29, 1951 [March 30, 1950], No. 7269/51. Class 81(2) An anaesthetic inhaler has provision for holding an ampoule, containing liquid anµsthetic, and a screw device for crushing the ampoule when required. The orifice in the neck of the ampoule, when crushed. is of small size such that the contents will only run out when in contact with an absorbent underlay. A rigid nosepiece 3, provided with a cushioned edge, carries a tubular body member 1 inside which is a further tube 12 having a closed bottom 13 in which there is a recess into which the tip of an ampoule 31 projects. The body of the ampoule is accommodated in an openended tube 17 carried in a rotatable ported plug 2. Non-return valves 20, 23 are provided in the nosepiece and a screw 14, carrying a plate 41, extends into the body to crush the tip of the ampoule The liquid thereupon is absorbed by a renewable strip 30 of absorbent paper. The ports in the plug 2 are so arranged that, by rotating the plug, a continuous variation is obtainable between pure air passing down between tubs 12 and 1 and all air passing across the anµsthetic strip 30 along a path running from the top of the plug 2, around the ampoule, up between tubes 17 and 12 and down between tubes 12 and 1. In order to admit controlled amounts of fresh air, the valve 33 may be moved on its pivot 34 to obstruct the aperture 32 to a greater or less extent.
