Abstract

628,709. Anaesthetic apparatus. EDMONDSON, W., and JONES, W. Oct. 6, 1947, No. 26774. [Class 81 (ii)] An analgesia appliance comprises a container A fitted with concentric tubes E, J having holes E<SP>2</SP>, J<SP>1</SP> and surrounded by baffles F and a cylindrical wick H. The lower part of the container is filled with the liquid to be vaporised and this is soaked up into the wick. The lower end of the tube E is closed by a plug E<SP>1</SP> and, when the patient breathes in, a non-return valve T opens. and air passes through passages P<SP>2</SP>, P<SP>1</SP> down to the perforations in the tube J; it is deflected outwards into the space surrounded by the wick and then passes inwards to tube E and up to the face mask attached to the outlet R<SP>2</SP>. An expiratory valve U is fitted in the upper wall of the top chamber R. The plate P may be rotated about the central axis so that, by co-operation with apertures in the fixed plates O, D, the relative proportions of air passing directly to the face mask and through the anµsthetic container may be varied.
