Abstract
221,121. Levi, J. Nov. 21, 1923. No Patent granted (Sealing fee not paid). Respiratory appliances.-Relates to an apparatus for supplying ether or like vapour by direct inhalation to the nostrils to produce local anµsthesia for dental operations. The appliance consists of a storage chamber a<1> for the anµsthetic, an air inlet a<3> to this chamber, and an outlet to an evaporating-chamber a containing cotton wool or the like. This latter chamber can be put in communication with extension tubes d, adapted for insertion into the nostrils, by means of a rotatable valve-plug c having ports c', c<2> which allow the patient to breathe through the appliance or direct from the atmosphere as required. A clip g is provided for attachment of the device to a head band worn by the patient, and a neck a<2> between the chambers enables a reclining position to be adopted by the patient without flooding the evaporating chamber.
