Abstract 445,218. Anaesthetic apparatus. HUMAN, J. U., 14D, Upper Montagu Street, Bryanston Square, London.. Jan. 7, 1935, No. 524. [Class 81 (ii)] In apparatus for endotracheal administration of anaesthetics comprising a tube or airway insortable into the mouth and throat for admission of air at the same time as anaesthetic vapours administered through a flexible tube inserted through the airway means are provided permitting lateral removal of the anaesthetic tube from the airway whereby the latter may be removed from the throat without disturbing the anaesthetic tube. As shown the air-tube comprises a main straight portion and a curved terminal portion and is divided into two parts a, b, the division may be made in a diametral plane passing symmetrically through the curved portion, or, as shown, in a plane at right angles thereto, the parts of the curved portion then having curved edges or, as shown, straight edges a<4>, b<4>. The upper ends of the parts a, b, have flanges a2, b<2>, provided with lugs a<3>, b<3> one pair of which is extended to lie adjacent to the other pair, the lugs being then locked together by a pin c, attached to the tube by a chain or the like c<1>. The lower ends of the parts have interengaging pins d and holes d<1>. The tube may be made from an aluminium alloy, may be longer than usual for use with all patients, and may be furnished with flattened bite portions. at its upper end. Instead of a plane division the division lines of the tube may be sinuous or of zigzag form. The anaesthetic tube e may have an end obliquely cut or, as shown, of flattened conical form having lateral apertures.
